The cloud has found a home for many uses, with lower costs and ease of administration as the main selling points. Yet there are still untapped possibilities for the cloud, including one overlooked area where the cloud can shine: testing. At Nexidia, we develop a large scale phonetic analytics framework, performing computational intensive operations across a cluster of servers, utilizing a MapReduce like strategy. This cluster can be as small as a single node, or as large as the needs demand. Testing large scale deployments in house has proven a real challenge; even with an unlimited budget, we cannot possibly anticipate all our future hardware requirements. The cloud has proven to be an excellent answer to this problem. With AWS (Amazon Web Services), we have developed a full automated testing harness in the cloud. This tool utilizes several of the AWS offerings:
Costs are kept in check, as the server instances are terminated as soon as the test case is complete. Testing in the cloud allows us to explore corner cases, find bottlenecks in the application framework and helps us form recommendations and best practices for our clients. Along the way, we have learnt many lessons about the cloud, AWS, and testing in general. This presentation aims to educate and inform anyone looking to the cloud for testing possibilities.
