Should you move your antivirus protection to the cloud?

This review compares three cloud-based antivirus services with a traditional antivirus product — as well as with one another. Find out if it’s a good idea to move your endpoint protection services to the cloud.

The products tested

The following cloud antivirus products were tested for this review:

  • McAfee Total Protection Service v5.0.0
  • Trend Micro TRVProtect v8 SP1
  • Panda Cloud Office Protection v5.04.01

These three products work only on Windows PCs since they each install software on the desktop.

To put these offerings into perspective, we compared them with Symantec Endpoint Protection Small Business Edition v12.0.1. In this traditional client/server antivirus product, a central server manages the various endpoint desktop clients. (While Symantec doesn’t have a comparable cloud-based antivirus service, its MessageLabs division has a cloud-based email protection.)

Note: Microsoft offers two free cloud-based antivirus services: Security Essentials and Intune. However, since both these products are designed for single PC installations, they weren’t reviewed for this article.

The testing process

We focused on how to prevent malware such as spam and viruses from being transmitted around your network, how to protect desktops from phishing and other attacks that can be launched from a browser window, and ways to beef up the supplied Windows firewall to detect and repel intrusions.

Our test PCs ran Windows XP with Service Pack 3 and Internet Explorer 8. On each, the C: drive was reimaged with Acronis True Image Workstation to return it to a virgin state without antivirus software installed. On one PC, we purposely installed Metasploit — a common hacking tool that contains all sorts of mischief — to see how each product’s scanner would react.

How cloud antivirus products work

Cloud antivirus services all work the same way — a small agent or client piece of software runs on each desktop and makes a connection to the central monitoring server in the cloud. As long as you have an Internet connection, updates to the virus signatures are automatic. In terms of protection and processing, most of the heavy lifting happens in the cloud, and as a result, the client needs little memory footprint. The central server’s console is where you keep track of infections, users and other reports, and it can be viewed from an ordinary Web browser.

Benefits for moving your endpoint protection to the cloud include the following:

  1. You don’t have to worry about users turning off protection software or forgetting to install the latest virus signatures.
  2. You can instantly see what is happening across your network and which PCs are protected.
  3. PC deployment is simplified because there is less software to install.
  4. In some cases, you can even initiate antivirus scans through the cloud service and, once again, not have to depend on individual user behavior.

Best Small Business Accounting Software

Freshbooks - cloud accounting for small business owners

The benefits of using accounting software for business are well known. When it comes to selecting the right product, though, the choices can be daunting, especially since switching from one accounting software package to another is not a trivial exercise in most cases. Examining your current and potential future needs can help you make the right decision.

If you are just starting a business as a sole proprietor/contractor or a very small business owner without employees, you can probably get by with a basic online invoicing/billing package like Sage One or FreshBooks that can handle invoicing, expense tracking, and produce basic reports to keep tabs on your business and satisfy your accountant and the taxman.

But if your business has employees, is incorporated or is likely to expand to such in future you will need a more robust (and expensive) accounting system such as QuickBooks or Sage 50 that is designed to perform double entry accounting, the basics of which includes:

  • Accounts receivable: moneys received and owing from customers
  • Accounts payable: moneys owing to vendors, suppliers, etc.
  • General ledger: the summary journal of financial transactions

Also typically included in the more expensive packages are features such as payroll, stock/inventory management, project management, financial forecasting, multi-user access, and a wider variety of reports and financial statements.

If your present needs are basic but you are contemplating future business growth make sure whatever accounting package you choose has a path to expand to your future requirements. In many cases, if the core product is missing a feature, you can fulfill your needs with third party add-ons to your existing software. There are hundreds of these available for most of the packages reviewed in this article, including payroll, customer relationship managment (CRM), analytics, and more (see QuickBooks add-ons).

This article contains the most popular small business accounting software packages for Canadian small businesses, ranging from basic to advanced in features (and cost). Some are online-based (cloud) only, some are available in desktop or online versions, and some are hybrids of both.

    Cloud service models

    There are three main types of cloud service:

    • Software as a Service (SaaS)
    • Platform as a Service (PaaS)
    • Infrastructure as a Service (IaaS)

    Software as a Service (SaaS) is by far the most common model and many people will have personal experience of using cloud-based applications from companies such as Google. Most of these SaaS applications are ‘commodity’ type services where there is little or no differentiation between users in different sectors eg email. PaaS and IaaS are more complex propositions whereby the institution can obtain ‘building blocks’ in order to store data or deploy applications in the cloud.

    Software as a Service (SaaS)

    Typically pronounced ‘sass’: A model of software deployment whereby a provider licenses an application to customers for use as a service on demand. The applications are accessible from various client devices through a thin client interface such as a web browser (eg web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, and application capabilities or maintain applications. There may be some limited user-specific configurable settings. SaaS breaks the link between machines and solutions, theoretically enabling customers to license only what they need. Because many people use the same basic service there is a rich source of ideas for improvements and additional features.

    SaaS has its origins in payroll bureaux and HR applications were amongst the first to market. The classic example of SaaS is the e-recruitment service Salesforce which accounts for a significant proportion of the market. This is not mere coincidence: recruitment is a business function where only a small subset of the data requires transfer to your core HR system. Other recent successes, which have had an impact on the education sector, include Google mail. Business functions which require a high degree of integration with other institutional systems may present more interoperability issues.

    Another feature which emphasises the end user, commodity nature of these applications (as opposed to previous applications for the corporate market) is that upgrades are rolled out to all users at the same time. The fact that you lose control of new releases to users means an end to the traditional cycle of testing and planned roll-out. The evidence from many social applications suggests that, on the whole, users will probably just get on with this and cope with the changes but the implications for IT support do need to be considered.

    A final point is that SaaS and cloud are not necessarily one and the same thing. This resource includes a section on risks of cloud computing that covers issues such as security and data protection. In the light of these issues it is worth noting that a number of trusted SaaS vendors do not actually use cloud hosting. NIST, (Badger et al 2011 ) the US National Institute of Standards and Technology offers an excellent summary of the architecture and basic operation of SaaS in a cloud computing environment that is of considerable use to anyone trying to understand the operational mechanisms and/or evaluate whether a SaaS cloud offering can satisfy particular reliability, compliance, or security requirements.

    Platform as a Service (PaaS)

    In this model the consumer creates or deploys applications onto the cloud infrastructure using programming languages and tools supported by the cloud provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage. They will have control over the deployed applications and possibly application hosting environment configurations.

    Infrastructure as a Service (IaaS)

    In this service model the institution outsources all of its infrastructure including servers, storage, associated networking, etc to an external provider. This model is sometimes referred to as Hardware as a Service. The service provider owns the equipment and is responsible for housing, running and maintaining it. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components, for example, the hosting of firewalls.

    Microsoft Azure vs. Amazon Web Services: Cloud Comparison

    Azure and AWS Compared

    Is your enterprise considering moving to cloud-based Infrastructure as a Service? Amazon and Azure are the two primary players, but which one is right for the needs of your business?

    It’s been 10 years since the introduction of Amazon Web Services (AWS). In that time a lot has changed about AWS and about the competitive landscape around it. One of those competitors, Microsoft Azure, has been operating since 2010. That’s not as long as AWS of course, but six years is still quite a while, and Microsoft has a history of making significant improvements to any product it really puts it’s mind to and starts iterating on.

    Both services have had enough time to create flexible, stable, and profitable products. At a high level, you will be comparing AWS, a known stable and reliable choice with a wide array of compelling offerings, against Microsoft Azure, a cloud offering by the authors of many of the closed source tools you are probably already using Visual Studio, SQL Server, and indeed Windows itself. With those two choices in mind, you can bet the decision won’t be easy.

    The Basics

    Amazon groups its Infrastructure as a Service offerings into the four categories of Compute, Storage and Content Delivery, Database, and Networking. All of those resources are used subject to Amazon’s security and identity services, which include Amazon hosted Active Directory, AWS Identity Management, AWS Certificate manager for managing SSL/TLS certificates, and even hardware-based key storage and management through AWS CloudHSM. You can monitor your infrastructure resource usage through management tools like Amazon CloudWatch, AWS Cloudtrail for tracking user activity and API usage, and AWS Config for tracking resource inventory and changes.

    Azure is going to be able to cover all of those broad categories, which it will call Compute, Data Management (which includes database) and Performance, and Networking. It will secure these services using a combination Azure Active Directory, Active Directory Federation Services, Multi-Factor Auth, and a sophisticated Role Based Access control model that it uses to extend a modern security architecture into the cloud where Group Policy doesn’t always make sense. Azure also has a number of services and integrations for in-depth monitoring and alerting on infrastructure performance metrics and logs.

    Licensing

    For some customers, the simplicity of licensing is a big part of the attraction of moving to the cloud. You are automatically charged for licenses you use based on usage. On the other hand, big companies probably already have lots of expensive licenses for the application servers they want to run on Windows like SQL Server or BizTalk and others. You’ll be glad to know that moving to the cloud isn’t automatically going to mean that those are wasted investments.

    Microsoft offer license mobility for qualifying application servers, so it’s important to find out ahead of time if your application is going be eligible for license mobility, and to keep in mind that Windows Server itself is not. Consider for instance running an on-premises Windows Server with SQL Server. If you spin up a VM in the cloud running the same stack, you will be paying for two Windows Server licenses since that license is charged by usage and it is not eligible for mobility. The SQL Server license, however, is eligible, and you can use the license you already paid for to run your SQL Server instance in the cloud.

    To learn more about License Mobility, you can read about it with Azure here and with AWS here .

    The Hybrid Cloud

    If you have the luxury of developing new apps, or even an entirely new startup from scratch, you probably don’t have to worry about a bunch of legacy infrastructure and users that you have to accommodate during your transition to the cloud. You can just do everything in the cloud from the start, and that’s really great.

    For most enterprises, though, the move to the cloud is a transition, and many of them simply have no plans to run everything entirely in the cloud. There are lots of reasons why that might be, but for them, their cloud journey is likely to end with some things running in the cloud, but others still running on servers in their own data centers fully under their own control.

    Microsoft has seen this pattern and responded with strong support for hybrid cloud configurations. With a hybrid cloud you can run cloud applications and deploy infrastructure assets and applications using a cloud model, but you can choose to use your on-premises compute resources when appropriate and use the cloud when needed. Crucially, a hybrid cloud allows you to transition between the two seamlessly.

    With platforms like Azure StorSimple, Hybrid SQL Server, Azure Stack and others, Microsoft clearly has the advantage in the Hybrid Cloud space. Amazon knows they need to make headway here (Fortune quotes Amazon CIO acknowledging work to be done), but they’re still playing catch up. Amazon does offer a few hybrid solutions like Storage Gateway, DynamoDB Local, and OpsWorks, but for now, the Microsoft has the upper hand.

    Government in the Cloud

    Private companies aren’t the only ones looking to save money. If you are an IT leader in government thinking about moving to the cloud, you should know that despite the heavy regulatory environment you operate in, it can be done. Both Amazon and Microsoft have dedicated Government areas of their respective clouds, cordoned off from the rest of their workloads, to ensure that your strict compliance needs can be met.

    Both government clouds tout their compliance with ITAR, DISA, HIPAA, CJIS, FIPS, etc. etc. and both are physically accessible only by screened U.S. persons. You can find case studies of their usage here for Amazon and here for Azure .

    Right now Amazon’s Gov cloud offering may have a slight edge just because it’s been operating longer and has more government clients that know how to deal with them. In this business, people that know how to shuffle the proper paperwork to get a request approved is no small matter, and Amazon has that relationship with more agencies than Azure right now.

    That being said, Azure does have the proper certifications, and some agencies have made the jump with them, so it can definitely be done. So if you find the rest of Azure’s offerings compelling, by all means, go for it.

    Microsoft Shops

    Microsoft has always had a focus on Enterprise customers, and as the people who write Windows and most of the other platforms these clients are using, it makes sense that their Azure integration story is good.

    Microsoft is also ensuring that Visual Studio and TFS integration are excellent and that Active Directory integrates well. You can use the same Active Directory accounts you have now to sign in to the Azure cloud offerings like Office 365 or your Azure SQL instances, seamlessly.

    For Microsoft shops, the cloud offered by the vendor of your platforms of choice, and the integrations it offers, can be a compelling argument.

    Open Source

    For Open Source shops, until recently the thought of using Azure as your cloud vendor was either impossible or at least a little odd. Microsoft hasn’t always had a great, or even a good, relationship with the open source community, but recently you might have noticed that relationship is changing.

    That bad relationship allowed Amazon AWS to open up a significant lead over Azure in the Open Source cloud hosting space. AWS has been Linux-friendly from the start and didn’t come from a history that was suspicious of open source. So if you’re an open source user, you’re probably going to be pretty comfortable with AWS and with all of the open source tools integrations it offers.

    PowerShell and .NET Core are open sourced and taking pull requests on GitHub. SQL Server runs on Linux and Hyper-V will be running Docker. The trend continues in Azure where you can now run Red Hat Enterprise Linux and Apache Hadoop clusters. Azure and Microsoft, in general, are really trying to embrace open source in one of the biggest strategy shifts we’ve seen out of Redmond in a long time.

    Amazon probably still has the upper hand here since it’s history with open source is long, and because Azure really does work so much more seamlessly if you are using Microsoft development tools than without them. But if you want to run open source in the cloud, don’t dismiss Azure without taking a look first to see if it will suit your needs because that gap is closing fast, and soon may be too close to call.

    Costs

    Any cloud platform vendor is going to argue that you can save money moving to the cloud. Unfortunately, making meaningful predictions of the actual cost of any actual workload can be fiendishly complex, and some of the considerations have as much to do with user behavior (shutting down VMs when not in use) as the actual workloads you want to run. Trying to make cost generalizations to help you estimate costs would probably be meaningless at best. Both Amazon and Azure have come up with provided cost calculators, which you can find at the links above.

    5 Private Cloud Providers Compared

    5 Private Cloud Providers Compared

    By Brian Kirsch April 7, 2015 12:37 PM

    Choosing the right private cloud solution is not an easy task. Here s how private cloud options from Microsoft, VMware, OpenStack, CloudStack and Platform9 compare in terms of management, compatibility, complexity and security.

    Last week, we took a closer look at the business and management considerations involved in building a private cloud. This week, we examine five private cloud vendors and what they have to offer in terms of management and administration, compatibility with your existing infrastructure investments, complexity in deployment and maintenance, and security.

    Private cloud software has to work with the virtualization layer that is providing the resources, enabling a management interface for the self-service aspect along with a management interface for the IT administrator. All of this has to be accomplished at a reasonable price and with adequate support if you plan on making your private cloud a part of your core business strategy. With all software investments today, and especially when it comes to virtualization and cloud software, the additional question of going with open source also has to be taken into consideration with the pros and cons that come with it. Thus below, you’ll notice a mix of proprietary as well as open source private cloud options and what each has to offer.

    Microsoft Private Cloud

    While Microsoft was a bit late to the virtualization and cloud arena, the software giant has spent considerable resources catching up and leveraging experience to avoid some of the mistakes other vendors in this space have made. Microsoft’s private cloud software is part of the System Center 2012 R2 offering. System Center incorporates several products under one umbrella including Virtual Machine Manager, Data Protection Manager, Endpoint protection and Operations Manager.

    • Microsoft’s System Center will support and centrally manage Windows 2012 Hyper-V hosts along with third party hypervisors from Citrix and VMware; KVM is a notable exception that is not included at this time. While the hypervisors are agnostic, the current lack of active third party network providers, including Cisco, is worth noting and may be limiting to some customers.
    • Microsoft’s private cloud offering focuses on the application life cycle combined with automation and monitoring in one package. This, coupled with a straightforward ability to create self-service portals based on mature IIS features, helps with the installation process. Leveraging the .NET framework does allow for additional extensions and troubleshooting.
    • Security can be leveraged off of existing Active Directory resources without the complexity of setting up single sign on (SSO). However this can open up additional security risks based on existing Windows Server vulnerabilities.
    • While the pieces in the package may not go feature for feature when compared to other offerings, the single SKU does make licensing and purchasing easier.

    VMware vCloud Suite Private Cloud

    VMware is one of the oldest players in the virtualization market and has an established record of performance and reliability. VMware’s products have the ability to scale to some of the most demanding workloads. VMware has incorporated several products into its private cloud offering allowing customers to choose ala cart what features they would like to use. VMware’s vCloud Suite comes in three different versions (Standard, Advanced and Enterprise) with each incorporating additional products and features.

    • VMware vCloud Suite does support other hypervisors, including Hyper-V and KVM, however extensive single pane of glass management is not advertised, as the favored hypervisor is ESXi.
    • The Advanced edition of vCloud Suites adds vRealize Business for vSphere and Enterprise version includes vCenter Site Recovery Manager on top of the vRealize Business Suite. vRealize Business offers cost, usage and metering ability while vCenter Site Recovery Manager is policy-based disaster recovery.
    • The vCloud Suite is packaged and requires license upgrades together as a single entity, however it is a collection of separate products, which can lead to confusion with support, and installation when compared to other offerings.
    • Frequent product name changes lead to confusion on what the products do, which ones are needed, upgradable or even owned in some cases.
    • vCloud has the ability to integrate with VMware’s software defined networking offering NSX, however this is an additional licensing fee with all versions of vCloud.
    • Established enterprise class security at the hypervisor and network layers for easy user integration with Active Directory single sign on and its complexities are required.
    • Support for VMware Virtual SAN and OpenStack allow for flexibility in both storage and third party cloud integration tools.

    OpenStack Private Cloud

    OpenStack is one of the most popular open source cloud operating options today. It has the ability to manage compute, storage and networking and deploy them is an easy to use, but somewhat feature limited dashboard. Unlike VMware and Microsoft, OpenStack does not have its own hypervisor.

    • OpenStack can be used with VMware’s ESXi, Microsoft’s Hyper-V, or Citrix Xen, however it is most often used with KVM, which is also open source. With more vendors including OpenStack APIs this will encourage more adoption.
    • OpenStack supports a wide range of software and hardware due to its open source nature. This allows for flexible architecture that can support both legacy and new hardware platforms.
    • While the capital cost of the software is free (since it’s open source) the soft cost in training your IT staff will have to be accounted for.
    • Similar to other open source offerings, a community support model is in place over paid maintenance, this may require trained staff for immediate support needs.
    • With so many community developers and quality feedback from users the complexity of installation and operation is simpler than might be expected. OpenStack is directly focused on the cloud platform and does not have additional pieces which reduces complexity.

    Platform9 OpenStack Private Cloud

    Platform9 is a private cloud provider based on OpenStack that does not reside onsite. Platform9 uses an OpenStack as a service model to allow organizations to manage their private clouds from an external cloud. While this might seem a bit unusual for a private cloud solution, the key point to remember is that your data still resides inside your data center, it’s simply the management piece that is external to your company.

    • Platform9 currently supports the KVM hypervisor with VMware ESXi in beta testing. Currently there are no plans for Hyper-V or Citrix Xen listed.
    • Being a hosted solution there is no software to install or upgrade. Platform9 handles all patches and upgrades to the OpenStack core.
    • Simplified user portal, image management and infrastructure discovery allow for reduced administrative overhead while leveraging the scalability and reliability of OpenStack.
    • Policy based deployments with infrastructure monitoring brings many of the popular public cloud features into the private cloud space without limited complexity.
    • No capital costs to get started; the solution is priced as a monthly service fee.

    Apache CloudStack Private Cloud

    Another contender in the open source private cloud space is Apache’s CloudStack. The CloudStack solution supports a wide range of hypervisors from VMware, Microsoft, Citrix and KVM. CloudStack is offered as a complete solution minus the hypervisor, allowing companies to have a robust management interface, usage metering and image deployment. Storage tiering and Active Directory are also included with limited software defined networking.

    • Unlike OpenStack, which focuses on the core cloud aspect, CloudStack is looking to provide everything under the single open source umbrella.
    • CloudStack is an economical approach to the private cloud with many popular features included. One concern is the quality of those features, along with the support that exists with open source software.
    • It includes a Java-based management agent, which may cause some concerns regarding performance, security and version splintering.

    Install OpenStack Juno on CentOS 7 / RHEL 7


    OpenStack is a free and open source cloud computing platform developed as a joint project of Rackspace Hosting and NASA. Users primarily deploy it as an Infrastructure as a Service (IaaS) solution. OpenStack cloud consists of many well know technologies like: Linux KVM, LVM, iSCSI, MariaDB (MySQL), RabbitMQ or Python Django.

    OpenStack architecture overview:

    1. Horizon: web browser user interface (dashboard) based on Python Django for creating and managing instances (virtual machines)
    2. Keystone: authentication and authorization framework
    3. Neutron: network connectivity as a service
    4. Cinder: persistent block storage for instances based on LVM
    5. Nova: instances management system based on Linux KVM
    6. Glance: registry for instance images
    7. Swift: file storage for cloud
    8. Ceilometer: metering engine for collecting billable data and analysis.
    9. Heat: orchestration service for template-based instance deployment

    In this tutorial we will install OpenStack Juno release from RDO repository on two nodes (controller node compute node) based on CentOS 7 / RHEL 7.

    Environment used:
    public network (Floating IP network): 192.168.2.0/24
    internal network: no IP space, physical connection only (eth1)
    public controller IP: 192.168.2.4 (eth0)
    public compute IP: 192.168.2.5 (eth0)

    Controller node network interfaces configuration before OpenStack installation:

    Compute node network interfaces configuration before OpenStack installation:

    First of all, stop and disable NetworkManager on both nodes (controller and compute):

    Update your system on both nodes (controller and compute):

    Install RDO repository (controller node):

    Install packstack automated installer (controller node):

    Generate answer file for packstack automated installation (controller node):

    Edit answer file (/root/answers.txt) and modify below parameters (controller node):

    Here attached: answers.txt file used during our installation.

    Launch packstack automated installation (controller node):

    Installation will take about 1-1,5h, we will be prompted for root password for all nodes (in our case: controller and compute):

    After successful installation we should get the output similar to the below:

    Test your installation login to the Horizon (OpenStack Dashboard), type the following in your web browser:

    Let s go back to the console, create OVS (openvswitch) bridges and bind them to physical network interfaces on both nodes

    After OpenStack installation we have following network interfaces on controller node:

    and on compute node:

    Type following commands on controller node:

    Modify ifcfg-eth0 file on controller node to look like:

    Modify ifcfg-br-ex file on controller node to look like:

    Modify ifcfg-eth1 file on controller node to look like:

    Connect eth0 interface to br-ex bridge on controller node.
    Below command will trigger network restart, so you will lose network connection for a while! The connection should be brought up again, if you modified ifcfg-eth0 and ifcfg-br-ex files correctly.

    Now let s connect eth1 interface to br-eth1 bridge (this will restart network too) :

    Now your network interfaces configuration on controller node should look like below (public IP is now assigned to br-ex interface):

    Check OVS configuration on controller node. Now port eth0 should be assigned to br-ex and port eth1 should be assigned to br-eth1:

    Modify ifcfg-eth1 file on compute node to look like:

    Now on compute node connect eth1 interface to br-eth1 bridge (this will restart network) :

    Check OVS configuration on compute node. Now port eth1 should be assigned to br-eth1:

    Time to check our new OpenStack cloud status and functionality.
    After each OpenStack installation a file /root/keystonerc_admin is created on controller node. This file contains admin credentials and other authentication parameters needed to operate and maintain our cloud. It looks like below:

    Let s source this file to import OpenStack admin credentials into Linux system variables, to avoid being prompted for password each time we want to invoke OpenStack command:

    Check OpenStack status on controller node to ensure mandatory services are running:

    Verify hosts list on controller node:

    Verify services on cloud hosts (execute on controller node):

    Thx for prompt answer .

    Yes I m using Liberty release.

    As it is if I try to run an instance on the faulty compute node. I got following error in neutron logs :

    Failed to bind port e3167852-2ff6-4b33-8cad-a901b29d23d8 on host lptxopsvnode01

    AFAYK. could it be related to this bug ?

    On the controller/compute node. no problem to start an instance.

    What is scalability? Definition from #cloud #scalability

    scalability

    In information technology, scalability (frequently spelled scaleability ) seems to have two usages:

    1) It is the ability of a computer application or product (hardware or software) to continue to function well when it (or its context) is changed in size or volume in order to meet a user need. Typically, the rescaling is to a larger size or volume. The rescaling can be of the product itself (for example, a line of computer systems of different sizes in terms of storage, RAM, and so forth) or in the scalable object’s movement to a new context (for example, a new operating system).

    An example: John Young in his book Exploring IBM’s New-Age Mainframes describes the RS/6000 SP operating system as one that delivers scalability ( the ability to retain performance levels when adding additional processors ). Another example: In printing, scalable font s are font s that can be resized smaller or larger using software without losing quality.

    2) It is the ability not only to function well in the rescaled situation, but to actually take full advantage of it. For example, an application program would be scalable if it could be moved from a smaller to a larger operating system and take full advantage of the larger operating system in terms of performance (user response time and so forth) and the larger number of users that could be handled.

    It is usually easier to have scalability upward rather than downward since developers often must make full use of a system’s resources (for example, the amount of disk storage available) when an application is initially coded. Scaling a product downward may mean trying to achieve the same results in a more constrained environment.
