Product development & Testing:- Today, businesses demand global vision, an in-depth understanding of customers and suppliers, demonstrated thought leadership and a consultative partnership approach to offer the highest possible returns on IT investment. We help businesses achieve these ends. Working closely with our customers as transformation partners, we deliver and implement innovative software solutions across a number of technology platforms. Overview Growing complexity of today’s applications, combined increase in competitive pressure, sky rocketing costs of application failure and downtime have catapulted the need for testing to new heights. While the pressure to deliver high-quality application continues to mount, shrinking development & deployments, geographically distributed organizations, limited resources and high turnover rates for skilled employees; make application testing the ultimate challenge. Shift to Independent Testing Business Units too are realizing the importance of Independent Testing from a number of business perspectives. Especially in multi-vendor and offshore scenarios, working on large, complex assignments across locations and time zones, increased demand for regulatory compliances mean that it is inefficient in both time and cost to employ anything other than Independent Testing. The reasons for this shift to Independent Testing can be easily gauged from the 4 important attributes governing any business unit: 1 Time & Cost Perspective • Increased Development Costs • Time to Market - Cycle Time Reduction • Cost of Fixing Delivered Defects 2 Management Perspective • Inadequate Testing • Inadequate Infrastructure • Internationalization Localization • Increased Interfaces 3 Complexity Perspective • Large scale Complex Assignments • Multi Locations - Geographies • Time Zones 4 Management Perspective • Testing Standards & Processes • Relevant Resource Skills • Tools Knowledge By employing Independent Testing Practice experts like Rootsan, businesses now have the comfort on knowing that their systems are being tested by impartial experts in the highly specialized field of software testing, using relevant resources, tools, standards and processes. Test Business Consulting Test Business Consulting is continually becoming of increasing importance to IT Industry, and to keep in pace with this paradigm shift offers 'Rootsan Test Business Consulting' as an unique offering. Due to changes in the international market, and the evolution of business, software is becoming more prominent in many companies, resulting in them shifting to become ‘software companies’. For example a car in 1980 contained 100, 000 lines of code, today it has over one million. It is therefore of great importance to CXO’s of companies that the impacts of software failures are minimal. 'Rootsan Test Business Consulting' offers the following types of services: • Assessment and Recommendations on Test Process Maturity • Providing information on how critical the impact of a software failure is, and how much investment is needed to get the software ‘back in shape’. This is particularly important today as testing has moved from being a ‘good thing to do’, to a necessity. • Calculating the cost to a firm that a failure has, and balances it against the investment spent. It is a very rare case when the money spent is equal to the cost of quality gained. Therefore Consultants can also go further and advise a company on the best way for it to spend its money. For example, it is common that companies spend large amounts on tools, but then do not have the human capital to utilize them. 'Rootsan Test Business Consulting' can advise the client on how to spend their budget more effectively, in order to receive the maximum dividends. • Advising companies on how they are able to create their own independent testing organizations. Companies may wish to establish such an organization as it is hard for a software team to objectively test their own creation. 'Satyam Test Business Consulting' can clarify the governance, make sure the interactions of the two teams are clear, and generally ensure that both teams are working towards the same goals. System Integration Testing System Integration Testing is based on black box testing techniques and is dependent on the specifications presented by the customer. It is used to validate an application’s accuracy and completeness in a ‘real life’ stimulation scenario which occurs once the application has been fully integrated. Interaction with a Graphical User Interface occurs to analyze the results. Systems Integration Testing is widely used and most types of testing can be done under this way of testing. For example, functional, regression, load performance, stress, security, compatibility and user interface testing. Regression Testing Regression testing is used to uncover regression bugs which occur when software functionality stops working or fails to work in its planned format. Typically regression bugs occur due to the unintended consequences of program changes. Regression testing is useful in the following cases: • Time constraints for QA cycles • Large number of test cases, test scenarios where client has to ensure effective QA for critical business processes • Large number of changes due to enhancements or Bug Fixes • Manual testing requires a large number of testing resources and time Regression testing can be performed at three levels; business process levels, profile levels and/or interface levels. The key to success in automation testing is the clear definition of goals so that it is possible to identify what needs to be automated. Based on the complexity of the test case functional experts might be used in order to verify or test typical business processes. Correct SAP testing is beneficial as many projects fail to test their SAP implementation correctly. They therefore suffer staggering financial loses and substantial fixing costs. SAP testing can minimize these costs, leaving the project in a better financial state. Regression testing can also track the quality of its output which leads to a higher quality of overall output. Performance Testing The scope of Performance Testing broadly lies within two extremes. At one extreme a project can instigate a system-level test to assess the complete business system for performance quality. At the other extreme, individual pieces of code and modules created by developers can be performance tested. Performance testing will be carried out to: Validate architectures, • Validate application scalabilities • Measure response times under load/stress • Diagnose an application, server and network • Identify Performance bottlenecks Performance test consulting, Load Testing, Stress Testing, Volume Testing, Scalability Testing and Application Profiling all fall under the umbrella of Performance testing. Performance testing brings with it the following value through the assistance to technology and network teams: • Study system tuning across the application, database, and operating system at optimum level • Establish performance viability of an architectural configuration • Accurately plan system capacity or size a particular server and network • Ensuring the system availability adequate in production Test Factory The Test Factory is a comprehensive Testing and Quality Management solution which offers a new approach to managing today’s testing services. Its logical framework is comprised of an infrastructure, resources and competencies. It is governed by a process driven methodology which provides integrated and comprehensive SLA driven and/or QA certification and is used for the automation of business processes. It occurs through the IT life cycle which covers the validation of pre-IT business needs to post-IT change management. The test factory framework enables the deliverance of unreliable applications which can have serious consequences for both businesses as well as to the Service Provider. Delivering applications on time, within budget and deploying reliable and dependable applications can be achieved by systematically following a combination of quality processes, as well as using the correct expertise. Features of the model include web portal operation and management, workflow automation, powerful metrics and reporting capabilities. The Test factory uses two types of Information flows. The first is from the customer down to Rootsan Consultants, and the second moves upwards from Layer 1 to Layer 4. This second type of information flow is used for the implementation and operation of the framework. The Test factory framework lends itself perfectly to the entire scope of the IT group of an enterprise. However there are a number of cases where it is especially useful: • End-to-End testing/IT Solution - The Test factory framework can be used at all stages of the IT lifecycle. This means that problem areas can be more effectively pinpointed and observed. • Manage Heterogeneous IT Environment – The Test factory provides process framework and automation transparent to different IT environments which is the most significant aspect of the Test Processes layer of the Test Factory Methodology Model. • Migration/Merging of multiple IT environments – The Test factory setup is especially useful in merging of applications to a standard environment. It enables the integration of new acquisitions by validating of the IT interoperability of disparate systems. There are many benefits in using the Test Factory. It is consistently collating and storing reusable components. This greatly eases resource management and the sharing of the resources and tools available to Test Factory between different projects. The continuous collection and analysis of metrics undertaken by the Test Factory also provide useful insights which lead to more efficient work practices. These include improved estimates of work efforts, more accurately set expectations, and continuous performance improvements. Further benefits of the framework include the following; • Reduced project management overheads • Management level reports on key quality and performance metrics • Enforced discipline through managed workflow • Help in Capacity planning through load testing and network performance prediction • Managed distributed test team members • Increased team productivity and efficiency through repeatable processes with reusable assets. Continuous Integration Testing Continuous Integrated Testing (CIT) is a new approach used to cost-effectively increase the number of testing cycles and application quality. At the same time it is also used to decrease the amount of time it takes to find problems and reduce the costs it takes to fix them. Features of integrated testing include reviewing source codes, automatic error detection, analyzing memory, analyzing code performance and locating untested code. The benefits of CIT include faster development, greater reliability and reduced developments and support costs. CIT helps developers in constructing reliable code and maximizing their productivity while at the same time improving the application’s quality and performance. CIT allows the developer to spend more time on development and less time in problem solving. These improvements all lead to a higher level of customer satisfaction. Functional Domain Testing Domain & Compliance testing is used in the following areas; • Online Business Management systems • Enterprise solutions • Regulatory compliance • Application management • Data warehousing & Mining • Packaged applications • Re-engineering or Conversion There are many advantages in using Domain & Compliance testing. They include more effective Knowledge transfer, improved testing results and a reduction in Cycle times.

Post migration also ensures seamless, defect-free migration Localization & Internationalization Testing The scope of localization and internationalization testing span from Verification to Validation. Internationalization testing enables a product to be used without language or culture barriers and localization testing is used to translate and enable the product for a specific local. Localization testing should include basic functionality tests such as setup, upgrade, and uninstall tests, application and hardware compatibility tests and the localized version of the operating system. Rootsan has met I18N and L10N standards through the use of the following; • Product Architects • Language Support Center Unit • Usability Experience management Group (UXM) • I18N "Off the shelf" I18N Product experts • Testing Professional (Rootsan) • Local native foreign nationals of the respective countries Rootsan uses the following types of I18N test methodology for internationalization testing; • Sufficiency testing -International character encoding methods • Functionality Testing • Linguistic Testing • Test international coding standards during development process • Rootsan also uses the following for Localization (L10N) test services; • Post localization • Readiness testing for local markets • Script-based Testing • Exploratory Testing As well as L10N functional verification testing; • User Interface – Verification & Validation - L10N • Multi - Platform Multi- operating system pre-deployment verification • Translation verification testing (TVT) Rootsan currently has capabilities in over 15 non-Indian languages. These include German, French, Japanese, Korean, Mandarin, Cantonese, Vietnamese, Spanish and Italian. Localization testing is highly beneficial to use, and is in fact is used in many areas. For example, UI, culture/locale-specific, language-specific and Region specific areas. It can also be used for basic functionality tests to setup and upgrade tests run and to plan application and hardware compatibility tests. The latter can be done according to the product's target region. Verification of linguistic accuracy and resource attributes, the checking of typographical errors and that printed documents and online help messages are consistent with each other can also be done, ensuring a more competent system overall. Test Center for Enterprise Applications Enterprise Application Testing is a challenging field in a high change environment. Enterprise application software perform business functions such as accounting, production scheduling and customer information tracking and bank account maintenance. Testing must keep up with the changes taking place in these fields and accommodate the individual customization in each one. Rootsan is committed to developing the following; • High competency • Re-usable assets; in order to reduce the Time-to-Market for the implementation of Enterprise Applications • Evolve best practices; to consistently provide high quality test services for Enterprise Applications • To become a preferred test service provider and partner the ISVs for testing the new releases and products • To become a leader in testing enterprise applications. It is essential that ERP implementations run smoothly without disruption. This is because they are complex; supporting multiple geographies, multiple business entities and diverse user populations. They are also among the largest investments that companies make because they are expensive and resource intensive to implement. Testing can ensure the smooth running of the system. Security Testing Security Testing can be divided into two sub sections; Network Security Testing and Web Application Security Testing. Web Application Security Testing is used to expose known vulnerabilities used by hackers in the internet. This test is done just before the application is launched. Potential security breaches can also be investigated. The following concepts need to be covered by Security Testing; confidentiality, integrity, authentication, authorization, availability and non-repudiation. Rootsan focuses on Web Application Security Testing. Applications are scanned for security vulnerabilities and manual reviews of the application security access controls are conducted. All traffic is directed to a web server such as http or https, neither of which are blocked by firewalls as they are legitimate traffic. As web servers are subject to frequent attacks due to their lack of firewalls, Web Application Security Testing helps to act against potential hackers accessing important information. Virtualization Management Virtualization is a technology, it creates abstraction layer on hardware and how they looks logically , changing your IT operations and infrastructure for good reasons. Lower management costs, reduced energy usage and centralized management are just a few of the many benefits of a virtual infrastructure. From desktop to server, Rootsan provides heterogeneous Virtualization Management solutions so you can realize the benefits of a virtual environment. From physical-to-virtual conversion through monitoring and management to backup and recovery, Rootsan automates and controls IT processes in your virtual environment to lower costs and simplify ongoing management. Virtual Desktop Management Virtual desktops provide centralized application access and management to reduce complexity, security concerns and costs. The Desktop Virtualization Group of Software (formerly Provision Networks), offers a customer-proven, sixth generation virtual desktop management suite called virtualization software. (Formerly Virtual Access Suite) to help you realize the benefits of a virtual desktop environment. Virtual Desktop infrastructure future proofs your application delivery and desktop deployments by being hypervisor agnostic while also providing support for multiple deployment options such as Terminal Servers, Blade PCs and VDI. This powerful flexibility transforms your physical desktops into virtual services and provides you options for whatever your future might bring. Rootsan supports Adeos, Mac-on-Linux, Parallels Desktop for Mac, Parallels Workstation, VMware Workstation, VMware Server types of virtualization software’s. What is virtualization and why use it Virtualization is a method of running multiple independent virtual operating systems on a single physical computer. It is a way of maximizing physical resources to maximize the investment in hardware. Since Moore's law has accurately predicted the exponential growth of computing power and hardware requirements for the most part have not changed to accomplish the same computing tasks, it is now feasible to turn a very inexpensive 1U dual-socket dual-core commodity server into eight or even 16 virtual servers that run 16 virtual operating systems. Virtualization technology is a way of achieving higher server density. However, it does not actually increase total computing power; it decreases it slightly because of overhead. But since a modern $3, 000 2-socket 4-core server is more powerful than a $30, 000 8-socket 8-core server was four years ago, we can exploit this newly found hardware power by increasing the number of logical operating systems it hosts. This slashes the majority of hardware acquisition and maintenance costs that can result in significant savings for any company or organization. When to use virtualization Virtualization is the perfect solution for applications that are meant for small- to medium-scale usage. Virtualization should not be used for high-performance applications where one or more servers need to be clustered together to meet performance requirements of a single application because the added overhead and complexity would only reduce performance. We're essentially taking a 12 GHz server (four cores times three GHz) and chopping it up into 16 750 MHz servers. But if eight of those servers are in off-peak or idle mode, the remaining eight servers will have nearly 1.5 GHz available to them. While some in the virtualization industry like to tout high CPU utilization numbers as an indication of optimum hardware usage, this advice should not be taken to the extreme where application responsiveness gets excessive. A simple rule of thumb is to never let a server exceed 50% CPU utilization during peak loads; and more importantly, never let the application response times exceed a reasonable SLA (Service Level Agreement). Most modern servers being used for in-house server duties are utilized from 1 to 5% CPU. Running eight operating systems on a single physical server would elevate the peak CPU utilization to around 50%, but it would average much lower since the peaks and valleys of the virtual operating systems will tend to cancel each other out more or less. While CPU overhead in most of the virtualization solutions available today are minimal, I/O (Input/output) overhead for storage and networking throughput is another story. For servers with extremely high storage or hardware I/O requirements, it would be wise to run them on bare metal even if their CPU requirements can be met inside a Virtual environment. Both XenSource and Virtual Iron (which will soon be Xen Hypervisor based) promise to minimize I/O overhead, yet they're both in beta at this point, so there haven't been any major independent benchmarks to verify this. Physical to virtual server migration Any respectable virtualization solution will offer some kind of P2V (Physical to Virtual) migration tool. The P2V tool will take an existing physical server and make a virtual hard drive image of that server with the necessary modifications to the driver stack so that the server will boot up and run as a virtual server. The benefit of this is that you don't need to rebuild your servers and manually reconfigure them as a virtual server—you simply suck them in with the entire server configuration intact! So if you have a data center full of aging servers running on sub-GHz servers, these are the perfect candidates for P2V migration. You don't even need to worry about license acquisition costs because the licenses are already paid for. You could literally take a room with 128 sub-GHz legacy servers and put them into eight 1U dual-socket quad-core servers with dual-Gigabit Ethernet and two independent iSCSI storage arrays all connected via a Gigabit Ethernet switch. The annual hardware maintenance costs alone on the old server hardware would be enough to pay for all of the new hardware! Just imagine how clean your server room would look after such a migration. It would all fit inside of one rack and give you lots of room to grow. As an added bonus of virtualization, you get a disaster recovery plan because the virtualized images can be used to instantly recover all your servers. Ask yourself what would happen now if your legacy server died. Do you even remember how to rebuild and reconfigure all of your servers from scratch? (I'm guessing you're cringing right about now.) With virtualization, you can recover that Active Directory and Exchange Server in less than an hour by rebuilding the virtual server from the P2V image. Patch management for virtualized servers Patch management of virtualized servers isn't all that different with regular servers because each virtual operating system is its own independent virtual hard drive. You still need a patch management system that patches all of your servers, but there may be interesting developments in the future where you may be able to patch multiple operating systems at the same time if they share some common operating system or application binaries. Ideally, you would be able to assign a patch level to an individual or a group of similar servers. For now, you will need to patch virtual operating systems as you would any other system, but there will be some innovations in the virtualization sector that you won't be able to do with physical servers. Licensing and support considerations A big concern with virtualization is software licensing. The last thing anyone wants to do is pay for 16 copies of a license for 16 virtual sessions running on a single computer. Software licensing often dwarfs hardware costs, so it would be foolish to run a $20, 000 software license on a machine on a shared piece of hardware. In this situation, it's best to run that license on the fastest physical server possible without any virtualization layer adding overhead. For something like Windows Server 2003 Standard Edition, you would need to pay for each virtual session running on a physical box. The exception to this rule is if you have the Enterprise Edition of Windows Server 2003, which allows you to run four virtual copies of Windows Server 2003 on a single machine with only one license. This Microsoft licensing policy applies to any type of virtualization technology that is hosting the Windows Server 2003 guest operating systems. If you're running open source software, you don't have to worry about licensing because that's always free—what you do need to be concerned about is the support contracts. If you're considering virtualizing open source operating systems or open source software, make sure you calculate the support costs. If the support costs are substantial for each virtual instance of the software you're going to run, it's best to squeeze the most out of your software costs by putting it on its own dedicated server. It's important to remember that hardware is often dwarfed by software licensing and/or support costs. The trick is to find the right ratio of hardware to licensing/support costs. When calculating hardware costs, be sure to calculate the costs of hardware maintenance, power usage, cooling, and rack space. There are licensing and support considerations for the virtualization technology itself. The good news is that all the major virtualization players have some kind of free solution to get you started. Even one year ago, free virtualization was not possible when VMware was pretty much the only player in town, but there are now free solutions from VMware, Microsoft, Xen Source, and Virtual Iron. In the next virtualization article, we'll go more in-depth about the various virtualization players Mechanical Design: Rootsan is a world leader in engineering services, offering end-to-end product development and engineering solutions to global majors.
