SRE serves as the perfect blend of skills to tighten the relationship between IT and developers – leading to shorter feedback loops, better collaboration and more reliable software. SRE teams will help add automation and context to alerts – leading to better real-time collaborative response from on-call responders. Additionally, site reliability engineers can update runbooks, tools and documentation to help prepare on-call teams for future incidents. 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 (MTTA) and Mean Time to Resolve (MTTR).

What should a Site Reliability Engineer know

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. Site reliability engineering (SRE) involves the participation of site reliability engineers in a software team. The SRE team sets the key metrics for SRE and creates an error budget determined by the system’s level of risk tolerance.

Site Reliability Engineer Responsibilities

A postmortem brings together all relevant parties for analysis of the incident. The goal is to analyze what occurred during the incident and find the root cause. The participants also determine how the incident can be prevented or fixed in the future.

SRE also relies on a foundation designed for a cloud-native development style. Linux® containers support a unified environment for development, delivery, integration, and automation. SRE relies on automating routine operational tasks and standardization across an application’s lifecycle. Faster application development life cycles, improved service quality and reliability, and reduced IT time per application developed are benefits that can be achieved by both DevOps and SRE practices. DevOps is an approach to culture, automation, and platform design intended to deliver increased business value and responsiveness through rapid, high-quality service delivery.

Documentation of processes and knowledge

Conducting post-mortem reviews involves the creation of a well-written post-mortem document, along with the key highlights. The document will include time and dates, stakeholders’ names, impact on users and revenues, root causes, lessons learned, and action points. Incident response tools ensure a clear escalation pathway for detected software issues.

Software systems are not rigid – they constantly evolve to meet traffic and business needs and must be configured appropriately at regular intervals. This component of the SRE job role involves configuration management for software products, datasets, and the production systems that execute services. In this context, site reliability engineers can also develop homegrown tools that aid in configuration design and management. Site reliability engineering (SRE) is the practice of using software tools to automate IT infrastructure tasks such as system management and application monitoring.

Without clearly defined roles for our SREs, we could have SREs that step on each other’s toes as they try different solutions without up-front coordination and communication. Well, for managing incidents, SREs need to employ additional professional skills to make sure everything goes smoothly. In summary, the less toil there is, the more time and resources are dedicated to making sure your software ecosystem runs reliably and the faster you can deliver business value.

  • Many factors may interrupt service availability at any given time, from a spike in demand due to sudden market trends or physical accidents.
  • However, SRE differs from DevOps because it relies on site reliability engineers within the development team who also have an operations background to remove communication and workflow problems.
  • The amount you make as an SRE will vary significantly based on the company you work for.
  • The views expressed on this blog are those of the author and do not necessarily reflect the views of New Relic.
  • Because of the nature of the SRE role, understanding development and coding can go a long way.

They may spend more time on improving or validating system and business-related metrics. And perhaps most importantly, the SRE will drive changes to team processes and culture. In addition to supporting development teams during on call, SREs also provide consulting and troubleshooting. 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.

Low-code Composable Experiences Speed Up Implementations

Today, most enterprises leverage cloud-based product environments, whether it is remotely hosted private servers, the public cloud, or hybrid infrastructure. Site reliability engineers must have expert-level cloud management skills to orchestrate the available computing resources for maximum uptime. They should also be conversant with databases running on SQL and NoSQL pipelines to support sophisticated applications that utilize a real-time flow of data streams. While most of this effort counts as toil and will eventually be automated, site reliability engineers must have a working knowledge of IT infrastructure. They should be able to use various IT monitoring tools available today including security information and event management (SIEM), network analysis tools, AIOps, etc.

According to him, people often confuse site reliability engineering as an additional layer in the hierarchy focused solely on monitoring and application/environment uptime. Site reliability engineers employ their engineering skills to automate and reduce the manual intervention necessary for administration tasks. When a high-priority page triggers, the engineer will investigate and diagnose the issue. The SRE might also pull in additional engineers or software developers if necessary. SREs provide monitoring services for systems so that teams can begin to track their SLOs and SLIs.

The SRE role ensures a site has the necessary functions to provide users with the requested services. In today’s automated world, that includes building self-service tools that provide greater availability, performance, and efficiency for users. As we continue to go online for more and more tasks in our daily lives, it’s increasingly important to keep these technologies up and running. Site reliability engineers are development-focused and solve problems with operations, scale and reliability. Site reliability engineering teams also focus on safety, health, uptime, and the ability to remedy unforeseen problems. Site reliability engineers will also have to add automation for improved collaborative response in real-time, besides updating documentation, runbook tools, and modules to ready teams for incidents.

He is also the founder of, which offers multiple services in technical training, project consulting, content development, etc. Post-incident reviews (PIRs) are another important responsibility of an SRE. A PIR is conducted after every significant incident in order to identify what went wrong and how to prevent similar incidents from happening in the future. PIRs typically involve representatives from all teams involved in the incident as well as any customers who were affected. The goal of a PIR is to identify systemic issues so that they can be fixed before they cause another outage. Part of being an effective site reliability engineer team is being available 24/7 to handle production issues as they arise.
