On the other hand, the operations team has to ensure seamless service delivery. Hence, the operations team uses SRE practices to closely monitor every update and promptly respond to any issues that arise due to changes. SREs build software that captures bugs and issues to improve system reliability. They then troubleshoot issues and escalations in development, operations, and production environments to ensure that infrastructure deployed during production is efficient and reliable.

The rest of the their time should be spent on development tasks like creating new features, scaling the system, and implementing automation. The concept of site reliability engineering comes from the Google engineering team and is credited to Ben Treynor Sloss. There are different SLIs, and which ones a site reliability engineer measures will vary by company.

Requirements and skills

SRE teams are in charge of proactively building and implementing services to make IT and support better at their jobs. This can be anything from adjustments to monitoring and alerting to code changes in production. A site reliability engineer can be tasked with building a homegrown tool from scratch to help with weaknesses in software delivery or incident management.

It means you need to communicate requirements and best practices in a way that doesn’t seem like a burden to service owners,” Anika Mukherji, a site reliability engineer at Pinterest, told Built In in 2020. They help software developers detect latency issues and improve software performance. Cloud-native applications are composed of microservices, packaged and deployed in containers, and designed to run in any cloud environment. A site reliability engineer is a software developer with IT operations experience— someone who knows how to code, and who also understands how to ‘keep the lights on’ in a large-scale IT environment. The concept of SRE is credited to Ben Treynor Sloss, VP of engineering at Google, who famously wrote that “SRE is what happens when you ask a software engineer to design an operations team.” Because an SRE team touches so many different parts of the engineering and IT organization, they can be a great source of knowledge and can be helpful for routing issues to the right people and teams.

What is a site reliability engineer and why you should consider this career path

Metrics are quantifiable values that reflect an application’s performance or system health. SRE teams use metrics to determine if the software consumes excessive resources or behaves abnormally.

Explore how applying AI and automation to IT operations can help SREs ensure resiliency and robustness of enterprise applications and free valuable time and talent to support innovation. Then, site reliability engineers are often tasked with action items for building or optimizing some part of the SDLC or incident lifecycle to bolster the reliability of their service.

• DevOps provides the philosophical foundation of what must be done to maintain software quality amidst the increasingly shortened development timeline.
• The goal of SRE is to enable higher change rates while maintaining resiliency and that coveted 99.999% uptime.
• To facilitate this, most SRE teams have an on-call rotation where each member takes turns being available during off hours.
• To learn more about the SRE interview process in FAANG companies, various rounds, and the interview questions you’ll have to solve, check out our blog on Google SRE Interview Process.
• Instead of striving for a perfect solution, they monitor software performance in terms of service-level agreements (SLAs), service-level indicators (SLIs), and service-level objectives (SLOs).
• They proactively ensure that the Quality Assurance parameters of each team are satisfactorily met to avoid unreliable systems going into production.

“Some of what works for Google doesn’t or can’t work for other companies.” A designated site reliability engineer may not make sense, for instance, at a 20-person startup, he explained. Site reliability engineering originated internally at Google in 2003 before finding a foothold in the broader development world. Service-level indicators (SLIs) are the actual measurements of the metric an SLO defines. In real-life situations, you might get values that match or differ from the SLO.

The benefits of Site Reliability Engineering

More importantly, site reliability teams provide documented procedures to customer support to help them effectively deal with complaints. A site reliability engineer is an IT expert who uses automation tools to monitor and observe software reliability in the production environment. They are also experienced in finding problems in software and writing codes to fix them. They are typically former system administrators or operation engineers with good coding skills.

Reliability engineers are dynamic professionals that play a variety of roles in ensuring systems, processes and products function properly and with maximum efficiency. Site reliability engineers oversee the functioning of a process or system and ensure that all functions are performing properly and as expected. They often collaborate with a variety of teams, such as operations and development. Monitoring is essential for keeping track of the health of company services and products. As an SRE, you should be familiar with various monitoring tools such as Prometheus, Solarwinds, Pingdom, Zabbix, and Zoho.

A day in the life: What does a site reliability engineer do?

They split their time between operations/on-call duties and developing systems and software that help increase site reliability and performance. Google puts a lot of emphasis on SREs not spending more than 50% of their time on operations and considers any violation of this rule a sign of system ill-health. Ortigoza started out with a degree in mechatronics engineering, for which he worked on industrial automation, he said, with some low-level coding and low-level electrical engineering thrown into the mix. His career started in the automotive industry, testing embedded systems, a role that laid the foundation for a future SRE position. “I was using most of my time to improve processes and create tools to make the everyday work easier,” he said.

Abhresh is specialized as a corporate trainer, He has a decade of experience in technical training blended with virtual webinars and instructor-led session created courses, tutorials, and articles for organizations. He is also the founder of Nikasio.com, which offers multiple services in technical training, project consulting, content development, etc. SREs are responsible for keeping systems up and running smoothly, and they https://wizardsdev.com/en/vacancy/sre-site-reliability-engineer/ need to have a deep understanding of how system components work together. They also need to be able to code, so they can automate tasks and create tools to help with their job. Part of being an effective site reliability engineer team is being available 24/7 to handle production issues as they arise. To facilitate this, most SRE teams have an on-call rotation where each member takes turns being available during off hours.

To ace that job interview, aspiring SREs should prepare to discuss everything from programming languages to network troubleshooting at varying levels of detail. Like most DevOps practitioners, Ortigoza points out that DevOps isn’t a job role, or something that a person performs. “It’s more of a culture … that everybody has to [do] their part, everybody has to contribute. And the most important thing of this culture is ownership … everybody is responsible for whatever thing we were doing,” he said. Our courses, Skill Paths, and Career Paths are a great place to start your SRE journey. You’ll gain the knowledge required to keep businesses up and running and build an impressive portfolio of your work.

According to him, people often confuse site reliability engineering as an additional layer in the hierarchy focused solely on monitoring and application/environment uptime. So, there you have it- a complete guide on what is a site reliability engineer and related aspects. If you are looking for a position in this field, it’s important to remember that being able to work well under pressure and make decisions quickly is just as important as having the technical skills required for the job. A career as a Site Reliability Engineer can be extremely rewarding, both financially and professionally. According to PayScale, the average site reliability engineering salary in the United States is $117,768 per year.
