Site reliability engineering (SRE) is the practice of using software engineering principles and applying them to operation and infrastructure procedures and problems. The goal is to create highly reliable and scalable software systems.
Site reliability engineers are responsible for a combination of the following: System availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning.
A principle of SRE is working together to connect development, IT operations, and applications so developers can create and deliver predictable real-world performance and availability. Then determine if a new service or feature can be successfully implemented and launched using three metrics we’ll discuss.
Service Level Agreements (SLA), Service Level Objectives (SLOs) and Service Level Indicators (SLIs) combine to play a key part in defining and quantifying what it means for a service to be available and performing as expected through clearly defined numerical measurements that can be tracked and reported against.
The service reliability of a new project and the development of applications, or infrastructure means understanding the key metrics below,
Service Level Objectives (SLO) – A service-level objective is a key element of a service-level agreement between a service provider and a customer. SLOs are agreed upon as a means of measuring the performance of the Service Provider and are outlined as a way of avoiding disputes between the two parties based on misunderstanding.
Implementing SRE principles and practices for your organization will take a unique approach to strategize and create processes that best meet the goals and requirements of your organization. But understanding a few key concepts first before then taking a deep dive will help.
Availability – Availability in SRE is defined by whether a system is able to function and perform as designed when required. The availability measurements can be used as a reporting tool and help determine the likelihood of the system performing as intended when deployed.
The goal and benefit of understanding these concepts and metrics is to keep customers happy, meeting expectations, team alignment, and to balance reliability and innovation rate.
For a more comprehensive understanding, refer to Google’s SRE Book, (chapter: A Collection of Best Practices for Production Services).
Site Reliability Engineering principles help cross functional teams to communicate so development and operations can have a clear understanding of the goals and there is a balanced and high degree of performance and availability for the application and service.
