1 Productized Services: Cloud Performance Testing Presented By Rupesh Garg, Wipro Technologies. 1

2 All About Cloud What is Performance Testing Cloud Testing Approach Cloud Service Providers Any Questions 2

3 Productized Services - Definition 3

4 Benefits of Productized services Allow the market to self-service their final deliverables by means of standardized packages with key parameters and KPIs, which dramatically shortens sales cycles and reduces cost of sales. Help in ensuring repeatability and consistency, and also reduce the amount of customer intervention in the process, which in turn improves profitability. Allow service providers to achieve efficiencies as deliverables are pre-defined, and enable them to offer differentiated and top-up services at a premium, thereby increasing profitability. 4

5 All About Cloud

6 Cloud? Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. 6

7 Cloud? Hybrid Clouds Deployment Models Private Cloud Community Cloud Public Cloud Service Models Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS) Essential Characteristics On Demand Self-Service Broad Network Access Rapid Elasticity Resource Pooling Measured Service Common Characteristics Massive Scale Homogeneity Virtualization Low Cost Software Resilient Computing Geographic Distribution Service Orientation Advanced Security 7

20 Why use the cloud for load testing? The cloud brings substantial benefits to load testing, whether the testing is carried out by a large corporation with an in-house performance center or by a start-up. o More flexibility: multiple generators, multiple internal resources etc. o More savings: you only pay for the power you use, when you really need it. o More realistic: you can test more realistic scenarios with load being input from different parts of the globe. 20 o No limits: you can progressively test heavier and heavier loads (the power available 2012 WIPRO is almost LTD limitless) INTERNAL to find the real limits of

21 Using the Cloud for Load Testing Ability to correlate the load with end-user response times and the impact on the systems We can borrow particular environment as per needs rather than going through the licensing and setup worries. Ability to control the distribution of the load Ability to use the same systems and configuration for subsequent testing With the help of Virtualization, it enables us to test multiple configurations, which was not possible few years back. Perfect coordination of the load injectors Know and understand the origination of the load (IP, geography) 21

34 SOASTA, Inc. provides services to test websites and web applications. [2][3] It is the leading provider of cloud-based testing services, and created the industry's first browser-based website testing product. Website tests include load testing, performance testing, functional testing and user interface testing. SOASTA provides cloud website testing with their product CloudTest, which simulates thousands of users visiting a website simultaneously using the Amazon Elastic Compute Cloud (EC2) service. SOASTA allows customers to use predefined tests or create customized tests to automatically test their web. "There was no way we could ever have simulated 500,000 users against our site in an internal test lab," said Christopher Roe, CTO, Qtrax. "By cloud testing we were able to identify connection issues immediately and fix the site prior to production. 34

40 Limitations with Cloud Computing "The cloud [test environment] doesn't reflect production environments -- applications run on specific [physical] servers, specific virtualization technology, specific networking and bandwidth, and that is hard to replicate, Forrester Research Inc. "Then there's the issue of cloud providers not supporting the technology that you use at all, like a specific HP blade server. Integration, in particular, is causing a lot of headaches 40
