Meeting customer demands had always been every organisation important mission in business. Nowadays, due to the never ending invention of various technologies, IoT devices in particular, as well as the introduction to Internet of Behaviour (IoB), the mission has become more crucial than ever. Ergo, organisations have to adopt approaches that enable them to succeed the mission. In software development, the answers are DevOps and Site reliability engineering (SRE). Why do companies need DevOps and SRE ?
DevOps approach is a work culture that promotes better collaboration between development and operation teams. When a company embraces DevOps, it gains the ability to deliver services with high quality at high velocity. However, rapid delivery of service may bring inevitable issues like missing out certain vulnerabilities and bugs detection which lead to less reliable service. In order to improve reliability, Google team introduced SRE, an approach that utilises software engineering to automate IT operations tasks such as incident and emergency responses and product system management.
Basically, SRE is considered as the application of DevOps. Like DevOps, SRE bridge the gap between the development and operation teams. What differs SRE with DevOps is that it depends on site reliability engineers to improve communication and workflow problems within the teams. SRE teams consist of software engineers or expertise in IT operations and software development skills while DevOps teams consist of developers and operations engineer that are skillful in both development and operations process. While the SRE teams share the same responsibilities such as code deployment, system maintenance, automation as well as change management, the DevOps teams are divided into a more specific tasks.
Importantly, despite the differences, together, the SRE and DevOps teams offer a far better product release. The SRE teams strengthen the DevOps teams through system performance and monitoring during the development of the new applications by the DevOps teams. As a results, a company obtain the ability to deliver reliable applications and services with shorter time to market.
