This paper presents our experiences in rolling out training and certification in a first level course on performance engineering across a large enterprise. We present data and lessons learned on the nominations(More)
Load Testing helps to capture performance at different load levels. It is naïve to assume that application performance at a certain load level may be in the same band that the load testing has pointed out. By introducing small spike for short duration we observed that applications either show resiliency, graceful degradation and recovery or total crash even(More)
Non-intrusive remote monitoring of data centre services should be such that it does not require (or minimal) modification of legacy code and standard practices. Also, allowing third party agent to sit on every server in a data centre is a risk from security perspective. Hence, use of standard such as SNMPv3 is advocated in this kind of environment. There(More)
