Introduction to Site Reliability Engineering (SRE) – A beginners Guide
What Is Site Reliability Engineering
The ever evolving world of technology never fails to impress. But amidst all the technological advancements, the need to have a sense of reliability in terms of digital services is paramount.
This is where Site Reliability Engineering (SRE) steps in. Let us explore what is site reliability engineering is and its need in the modern web scenario.
As businesses have started depending majorly on their online presence, there has been an ever-increasing need to enhance the efficacy of operations so that the quality of performance can be kept in check.
What Is SRE
SRE is the systematic approach through which software can be made more reliable. This not only enhances the quality of deliverables but also puts together a plausible system to handle any kind of anomalies or discrepancies.
What Are The Key Principles Of SRE
The following set of principles guide site reliability engineering to create a dynamic and robust network of software systems.
● Service Level Objectives (SLOs)
SLOs are clear and crisp performance targets that are set for the software. They measure the quality of the service being rendered. Learn more about SLO vs SLI here
● Automation
This is a very important principle of SRE. With greater automation, any chance of human error can be curtailed.
● Incident Management
When we talk about a site reliability engineer, there has to be a proper mechanism in check that can identify the probable root of any problem and accordingly take corrective actions.
● A Budget For Errors
An error budget signifies the scope for error or time-lapse that a service provider can incur without hampering the stipulated nature and timeframe of the deliverables.
● A Pragmatic Approach For Fixing Problems
SREs focus on creating a productive approach for dealing with problems where the idea is to address and alleviate the root cause instead of going to and fro on the problem itself.
● Scalability
Site reliability engineering aims to ensure that the site can handle an unexpected spike in web traffic without hampering the quality of deliverables.
● It Is A Dynamic Process
SRE teams undertake regular efforts to ensure that the reliability and efficacy of the software system can be greatly enhanced. To facilitate this, data is regularly analysed and studied.
Conclusion
Site reliability engineering is rooted in an approach to solve problems. SRE team’s work in synergy with developmental teams and other departments across the organisation, so that an environment of shared responsibility can be fostered. We live in a world, where we are deeply dependent upon technology and therefore, reliability becomes a high benchmark for a seamless flow of operations. SRE combines engineering excellence with a smooth flow of digital operations.
