“You have to architect for it by building systems that are resilient by design.” This architectural approach recently helped Dynatrace to withstand an AWS outage in Germany. Automatic delivery, resiliency, and auto-remediation helped to ensure critical systems weren’t affected. Traditionally, a major goal of operations teams is to improve uptime. This single-dimensional approach looks for the coveted “five nines” of uptime, or 99.999%, which translates to just over five minutes of downtime per year. 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.

Who is a Site Reliability Engineer

They also monitor critical applications and services to minimize downtime and ensure their availability. They will need to have knowledge of various automation tools as they are usually responsible for building and integrating software tools to enhance an organizational system’s reliability and scalability. The main purpose of SRE is developing software systems and automated solutions for operational aspects. Thus, SRE does the work traditionally done by operations but instead using engineers with software expertise to solve complex problems.

Site reliability engineering

SLIs count failures per request, by calculating request latency, throughput of requests per second, or failures per request per time. SLOs are derived from threshold and percentage, and represent the success of SLIs over a certain amount of time. Toil management as the implementation of the first principle outlined above. Systems design with a bias toward reduction Site Reliability Engineer of risks to availability, latency, and efficiency. If you want to take full advantage of the agility and responsiveness of DevOps, IT security must play a role in the full life cycle of your apps. Infrastructure optimization, including right-size cloud resources and adding or removing resources like central processing unit and random access memory as needed.

Who is a Site Reliability Engineer

For this portion of the job, SREs can use a product like Scalyr to monitor and alert on any potential issues. This allows real-time system monitoring as well as analysis of long-term reliability trends. In fact, you can get started today with a free trial of Scalyr that can give you the visibility you need to monitor all your systems. Not only does reducing toil make the processes repeatable and automated, but it also increases the amount of time SREs have to build new tools and investigate infrastructure changes that further improve site reliability. New services and applications combined with evolving enterprise demands mean there’s always work for SRE teams, and there’s always room for improvement.


According to SRE best practices from Google, site reliability engineers can only spend a maximum of 50% of their time on operations—and they should be monitored to ensure they don’t go over. 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. As with system monitoring, on-call support also provides metrics that can be used to drive improvement. With on-call support, site reliability engineers work to reduce metrics like Mean Time To Acknowledge and Mean Time to Resolve . As you may suspect, SRE roles require actionable metrics that drive our systems to improve aspects of system reliability.

An incident commander who maintains a high-level view of everything occurring. When an outage occurs, for example, there could be dozens of ways to diagnose and attempt to resolve the issue. And your first step involves using the monitoring and metrics you have to diagnose the issue.

A site reliability engineer, or SRE, is a role that that encompasses aspects of both software engineering and operations/infrastructure. It also encompasses a strategy and set of practices and principles across service offerings and is closely tied to DevOps and operations. The term site reliability engineering first came into existence at Google in 2003 when a site reliability team was created. Since then, the concept of site reliability engineering has evolved and made its way into the broader software development industry and is now its own role within organizations.

You are experienced in CI/CD and know how to develop and operate continuously deployed applications in production. However, other companies that are further along in the journey may have eliminated company-wide outages. They may spend more time on improving or validating system and business-related metrics. In addition to supporting development teams during on call, SREs also provide consulting and troubleshooting. The engineers who execute processes or modifications to the infrastructure or systems.

The report uncovers the challenges SREs must overcome, and what the future of SRE looks like. Are you looking to transition your career from another role and become a site reliability engineer? Many organizations want to simplify or scale down their data centers — but they won’t disappear. Google Cloud lets you use startup scripts when booting VMs to improve security and reliability. In here I’ve played different development, operations and coordination roles and also obtained a PhD degree in computer science.

  • It can be very frustrating and demanding sometimes, and pieces can sometimes go missing, but once you have finished it, there is a great deal of pride and accomplishment.
  • SRE teams will help add automation and context to alerts – leading to better real-time collaborative response from on-call responders.
  • For example, a site reliability engineer may be involved with help desk tickets, on-call incidents, manual tasks, etc.
  • They also help provide realistic objectives for the future and might advise on proper SLAs for customers.
  • SLIs count failures per request, by calculating request latency, throughput of requests per second, or failures per request per time.
  • Standardization and automation are at the heart of what an SRE does, especially as systems migrate to the cloud.
