Abstract:
The idea of zero downtime deployments has now become imperative as organizations that are into modern software development insist on continuity of service delivery and high availability. Site Reliability Engineering (SRE) gives approaches for dealing with such deployments successfully so clients interact with an uninterrupted service. Generally, this journal article discusses the main concepts worth emphasizing in the SRE process and explains how to apply them to establish zero downtime deployments in present-day business conditions. In the Lyft SRE case, blue-green deployments, canary release, feature toggling, and rolling updates help SRE teams keep the system available for users but deliver new features regularly. It provides a discussion of several issues, especially during zero downtime deployments, including handling databases and the state of the applications. Moreover, we explore how setup and deployment automation tools such as Kubernetes, Jenkins, and Continuous Integration/Continuous Deployment (CI/CD) pipelines are used to automate setup and deployment processes. To fill this gap, the article carries out a literature study of the various zero downtime strategies on system reliability, performance and user experience and examines real-life case studies. Several approaches are suggested to achieve highly flexible deployment, namely, monitoring, testing, and rollback procedures. Lastly, the recent trend of zero downtime deployment concepts is discussed in the context of future enhancement of deployment technologies to fulfill emerging requirements for real-time solutions.
