Expanding System Lifespan
Explore how to identify and prevent common threats to distributed system longevity like memory leaks and data growth. Learn why typical testing environments often miss these issues and discover strategies for effective longevity testing, including running long-term load tests and using development or production environments to catch elusive bugs. This lesson helps you enhance system stability and maintain uptime over extended periods.
We'll cover the following...
System longevity
The major dangers to any system’s longevity are memory leaks and data growth. Both kinds of sludge can stop a system in production and both are rarely caught during testing.
Testing makes problems visible so we can fix them. Following Murphy’s Law, whatever we do not test against will happen. Therefore, if we do not test for crashes right after midnight or out-of-memory errors in the application’s forty-ninth hour of ...
