4 Executive Summary Cloud Computing is now the latest technology that seems to have made an impact on businesses, They see huge benefits in the embrace of this Technology. The impact can be both short term and long range. The Advantages vary from Cost reductions in cost, Technology flexibility and location independence. But with the perceived advantages also tag along potential Risks like security, privacy, availability, performance and integrity. To Mitigate Risk and success implementation, effective testing will be a key to any Cloud Solution, this will ensure the solution is aligned to the Needs of Business. The purpose of this paper is to see the influence of a Cloud Computing solution on Testing and new found challenges that come with cloud technologies. Cloud computing is the latest trend that has caught onto the computing world, with new Technologies come misconceptions and the same is the case with Cloud Computing, often referred to as Grid Computing. Even though a Cloud solution may have similarities to Grid computing, Cloud Computing is a much more generalized term in where there will be no local computing or infrastructure that is owned, rather data centers operated by outsourced compute and storage vendors.

5 Table of Contents 1 CHALLENGES WHY ARE BUSINESSES MOVING TO THE CLOUD? SOFTWARE TESTING, A LOOK AHEAD ABOUT PRAKAT...10 Page 5 of 10

6 1 Challenges Minimal control on Environment When IT infrastructure is owned by a third party vendor, will the business have control on : Data Down time Technology upgrades External Factors that affect their Applications Security by creating too many layers and too many options in the environment. Privacy concerns Ensure sensitive information is not leaked on the cloud Data Integrity Using third party applications doesn t corrupt data. Availability Cloud Computing solutions depend on infrastructure, how to ensure Maximum uptime. Business impact confident the technology or tools are right to address specific Business functionality needs. Testing all the layers from the application to the cloud service provider to identify bottle necks along this path and tuning will be ever complex than before. Enterprises were deploying the applications on data centers for years. The challenge was to manage highly scalable applications and to see that these applications users have a good user experience in terms of speed and performance. This process was resource intensive. With the cloud infrastructure, enterprises deploy and run applications on third party infrastructure. Now if the application can be accessed via a Internet or mobile device, the cloud provider will test to ensure the server is available but application on its own needs to be tested to see the page load times etc. Also there are multiple layers that can cause a bottleneck, the cloud environment, the network, the client and all other elements between the user and the cloud. The other challenges in testing enterprise applications on the cloud arise from the Hardware, Software, Database Layer and Networking considerations, and iterative development methodologies Page 6 of 10

7 2 Why are businesses moving to the Cloud? Sample Cloud Workflow Scalable Current business models like Software as a Service (SaaS), Infrastructure as a Service(IaaS) etc, scaling up is easy and almost instant. Geographic independence With clients and a high speed connection, business can access and deploy their solutions in locations the business demands without having own infrastructure in that Geography. Reduced costs The whole reason for cloud or Virtualization becoming a hot topic is that it gives end Customers a flexible pay as you go model to reduce their overall spend and not horde too much infrastructure. Hardware Optimization With a huge stack of servers available, the system can utilize lesser used hardware in the stack which will optimize processing and output timelines. Flexible Since the IT infrastructure and Applications are not owned, business can easily reduce costs by Unsubscribing for the services or infrastructure unlike Owned infrastructure. Page 7 of 10

8 3 Software Testing, a Look ahead. Software testing is going to get commoditized and it s going to need a larger pool of testers to be available globally. The reason being that more and more applications are becoming consumer focused. Given that, you need different kinds of skillsets evolving in the software testing space. happen in the infrastructure and environments for testing. Third, people s skillsets will change dimension. We will see more depth evolving in domain technology and infrastructure as we go. So down the line you will see certain kinds of testers being focused on domain testing, a certain set of testers focused on solving infrastructure problems around testing, and a certain set of people will focus on building more robust and more innovative tools and solutions around testing. A lot of the current tools are going to become obsolete because people want more sleek, quick to use, simple to use and economical solutions. A lot of old tools that have been there for years will slowly start dying and newer things will be evolving. As has been mentioned, more and more disruption will happen in the way service delivery will happen. Second, more changes will Prakat Tips Applications which are designed and developed for the cloud most effectively leverage the properties of the cloud Transitioning an existing enterprise application to the cloud has it s challenges An ISV taking their on premise application to a cloud based model introduces many more challenges Page 8 of 10

happen in the infrastructure and environments for testing. Third, people s skillsets will change dimension. We will see more depth evolving in domain technology and infrastructure as we go.

9 Conclusion Summing up, to test effectively tester in the cloud world, the tester needs to have a combination skill of excellent testing skills, the ability to use the basic tools when testing, very good understanding of the underlying technology and other software products which goes into enabling the application on the cloud. So that is the piece on how you test applications on the cloud. References: Page 9 of 10
