Site Reliability Engineering, used by software service providers, allows organizations to adopt new responsibilities and guarantees to provide the best reliable service. Traditionally, providers were more concerned about delivering a reliable service. The company is learning that delivering a reliable service and proving reliability are two different but significant things. Is it SREs responsibility? Why and how are they ensuring reliability? Explore the topic of reliability and SRE in this blog.
SRE is a set of processes that allows members to adopt new responsibilities quickly. It ensures reliable delivery. Traditionally, operators were responsible for ensuring the reliability of the software and infrastructure. Operators needed to handle infrastructure, configuration, processes related to the application, and product completion. It lowered the effectiveness of the operation.
SRE has changed the traditional rules of making the application reliable. It has removed the bottlenecks, burdens, and glass ceilings. SRE is focused on making the whole process and steps, from architecture to design, reliable. The growing demand for site reliability engineering has proven that SRE is the pillar of software engineering. Building software architecture, enhancing user experience, automated testing, etc., are the inseparable parts of SRE.
SRE and the Reliability of the Software
In DevOps, software development and software operations are combined approaches. Here, operators are responsible for the reliability. According to SRE, challenges of reliability are not operators’ tasks but engineers’ tasks. Here engineers use different types of tools to get the desired outcome. Thus reliability engineers work with the DevOps team in various stages, including:
· Make reliable architecture and design.
· Ensure reliable deployment.
· Test all the code and functionality.
· Monitoring deployment process.
· Build a continuous feedback loop.
The above stages are all parts of the software development lifecycle. Delivering a reliable application to customers drives the reliability of the architecture and development process. As a part of SDLC, SRE can operate within the main principles. The principles contain, single source of truth (software version control repositories), fail fast (testing before releasing to the production), total transparency, metrics, etc.
SRE focuses on a collaborative effort. SRE believes in working hand in hand with other teams to make the software a reliable service.
