IT reliability contributes immensely to business reliability. IT reliability is being achieved through resilient and elastic IT systems (both software and hardware). With the quicker adoption of microservices architecture, the realization of resilient and elastic software systems is being made easy. Microservices are being touted as the best-in-class application building block, and hence there are enabling patterns for microservices development, deployment, integration, and operations.

In the next chapter, we will focus on DevOps under Site Reliability Engineering (SRE), since as automation and DevOps play a big role in the SRE journey.
