Whats An SRE? Site Reliability Engineer Roles and Responsibilities

It’s harder to develop quality SRE-style results with this implementation. Acloud-nativedevelopment approach—specifically, building applications asmicroservicesand deploying them incontainers—can simplify application development, deployment and scalability. But cloud-native development also creates an increasingly distributed environment that complicates administration, operations and management. An SRE team can support the rapid pace of innovation enabled by a cloud-native approach and ensure or improve system reliability, without putting additional operations pressure on DevOps teams. Site reliability engineering is the application of software engineering skills and principles to monitoring and maintaining system reliability. The practice involves incident response, as well as working proactively on tools to support system maintenance and improvements.

  • “Site reliability engineers ensure systems stay reliable, resilient, and available,” he adds.
  • “It’s more of a culture … that everybody has to 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.
  • Having such engineers in your organization will help reduce your operational costs while improving the reliability of your systems.
  • With this in mind, SRE teams measure, and test, and explore their systems.

This could be trying to reach 99.999% availability, or just 90% availability. It all depends on the demands of the business and the customer of what’s required. Jacob Hall is an experienced Site Reliability Engineer and well versed in open-source tools and commercial products.

On the contrary, it’s a highly creative, stimulating, and technically challenging role. SRE eventually became a full-fledged IT domain, aimed at developing automated solutions for operational aspects such as on-call monitoring, performance and capacity planning, and disaster response. It complements beautifully other core DevOps practices, such as continuous delivery and infrastructure automation. Both SRE and DevOps work to bridge the gap between development and operations teams to deliver services faster. The close collaboration of both teams with development, operations, and support teams leads to better products, faster shipment, fewer incidents, and happier developers and customers.

SRE teams are responsible for how code is deployed, configured, and monitored, as well as the availability, latency, change management, emergency response, and capacity management of services in production. Because an SRE engineer’s main focus is on automation, this means that he/she enhances performance, efficiency and monitoring of software development processes. At smaller companies, it is even possible that the two operate interchangeably. However, as the number of developers increases, the lines between SRE and platform teams become a little less blurry. Both disciplines, DevOps and SRE, aim to enhance the release cycle by helping dev and ops see each other’s side of the process throughout the application lifecycle. They also advocate automation and monitoring, reducing the time from when a developer commits a change to when it’s deployed to production.

In addition to supporting development teams during on call, SREs also provide consulting and troubleshooting. A communication role for relaying the right message to customers and management. Once you have the data or symptoms available, you’ll have to manage the incident properly. You’ll need someone to take point on facilitating and coordinating the actions of all involved. This balances on-call duties with more in-depth engineering and automation activities, reducing burn out improving focus when it’s needed. When you put software developers in a position where they repeat the same functions day in and day out, they’ll be driven to automate.

With the ever-growing importance of technology in our world, it’s no wonder that careers in this field are on the rise. SREs, serve as a bridge between IT and developers, which can lead to improved collaboration between these two groups. This improved collaboration can lead to shorter feedback loops and more reliable software. While the roles of site reliability engineer and DevOps engineer may, at first glance, appear to be quite similar, there are actually a few key ways in which they differ.

This is because you will often need to relay important information about system alerts or outages to other members of your team. Let’s take a look at the most important site reliability engineer skills that you need to have in order to fulfill this role. As we discussed, SREs spend time on both technical and process-oriented responsibilities. For example, a newer company may need SRE support in getting general outages under control. In this post, we’ve discussed various activities that site reliability engineers participate in.

What does a Site Reliability Engineer do

While DevOps is more concerned with automating IT operations, SRE teams focus more on the planning and design aspects. While SREs work to increase reliability and availability of production systems to meet customer demands, it’s impossible to achieve 100% uptime. The goal of SREs is to work towards the highest attainment of reliability and availability possible to satisfy the customer.

Why You Don’t Have To Work “In Tech” To Have a Technical Career

SREs are a crucial part of modern technology organizations, as they are responsible for ensuring the availability and performance of systems and services. With their technical expertise and focus on reliability, SREs play a key role in helping organizations deliver high-quality systems and services to their customers. A Site Reliability Engineer, or SRE, is an engineering discipline that focuses on the availability, performance, and reliability of systems and services. SREs are responsible for ensuring that an organization’s systems and services are able to meet the demands of its users, and for implementing best practices and processes to prevent and mitigate outages and other issues. The tools and software solutions that site reliability engineers can vary greatly from organization to organization.

Second, it’s a role that is in high demand and will only become more so as the world increasingly depends on technology. Third, it’s a challenging and interesting field that offers opportunities for continued learning and growth. So, there you have it- a complete guide on what is a site reliability engineer and related aspects.

How Can SREs Achieve Success?

As such, the SRE team needs to have a good understanding of both the codebase and the infrastructure in order to effectively debug production issues. SREs have been compared to operations groups, system admins, and more. But the comparison falls short in encompassing their role in today’s modern software environment. And though they may have a background in system administration, they also bring software development skills to the role. Everything the organization does in the value stream process should answer the question “how do we ensure this runs in production reliably? They can become mentors and ensure that resiliency is a top priority for both developers and operations.

What does a Site Reliability Engineer do

In this scenario, the SRE will assess current issues and determine which can be improved with automation or engineering effort. Site reliability engineers have a lot of different responsibilities because there are a lot of ways to look at and solve reliability problems. And these responsibilities may vary based on the company size, domain, team size, and other factors.

Their goal of ensuring consistent product quality marries well with the SRE goals and their experience helps them fit in to SRE teams quickly. They are often among the most astute chaos experiment designers and help teams find ways to be even more intentional about finding and fixing problems before anyone else does. Site reliability engineering is a set of principles and practices that incorporates aspects of software engineering and applies them to IT infrastructure and operations.

Build tools and automation that eliminate repetitive tasks and prevent incident occurrence. Develop, coach, mentor individuals and teams and ensure high performance in a fast-paced environment. Provide training and education to engineering as a whole on infrastructure and internal tooling. API caching Site Reliability Engineer can increase the performance and response time of an application, but only if it’s done right. Site reliability engineering and DevOps share a close relationship — but it’s not always clear what, exactly, that relationship is. Walk through the basics of SRE, and its place in DevOps methodologies.

What does a Site Reliability Engineer do

An SLO is an internal metric, and an SLA is the customer-facing metric, many times codified in the customer contract. The purpose of an SLO is to serve as a warning that the system behavior is getting close to the SLA and requires immediate attention to restore healthy operations. A Site Reliability Engineer can use a root cause analysis solution that identifies when a malfunction inside one of these databases causes a problem in the checkout process. The RCA system will send out an alert so admins can quickly address the problem and get the checkout process working again. An SRE can save the company many thousands of dollars this way — even over the course of a few hours. Reactive site engineering is all about fixing these and other kinds of problems that can pop up at any given time.

Essentially DevOps is focused more on delivering value to the customer from the Development team.

To effectively manage company services, you will need to have a deep understanding of various operating systems such as Linux, Windows, and macOS. Many companies today use distributed systems in order to achieve high availability and scalability. As an SRE, you will need to have a deep understanding of how distributed systems work in order to be able to troubleshoot and optimize them. In order to release code changes safely and efficiently, you will need to be well-versed in continuous integration and continuous delivery pipelines. As an SRE, you will need to be proficient in at least one coding language. This is because you will often be required to write code in order to automate tasks or build tools.
