Technology choices are made, and because of a variety of reasons--such as multi-year licensing cost, tightly coupled links to mission-critical systems, long-standing vendor relationships--you feel “locked into” those choices. In this InfoQ emag, we explore the topic of cloud lock-in from multiple angles and look for the best ways to approach it.
This eMag aims at providing an overview of an example set of tools that would constitute a typical toolchain. These are popular tools today, but you should look at them as illustrations of the kind of tasks and workflows you might need to perform in your organization as you move along a DevOps path.
This eMag examines topics such as how Twitter re-architected its code-base to improve stability and performance, the approaches Netflix uses to be hyper-resilient, and how Java is replacing C++ for low latency coding. We also look at some lower level tricks such as feedback controls for auto-scaling, and using memory and execution profiling to identify performance bottlenecks in Java.
