clear neutral encyclopedic terms may 2023 learn how and when to remove this message site reliability engineering sre also known as service reliability engineering 1 is a discipline in the field of software engineering and it infrastructure support that monitors and improves the availability and performance of deployed software systems and large software services which are expected to deliver reliable response times across events such as new software deployments hardware failures and cybersecurity attacks 2 there is typically a focus on automation and an infrastructure as code methodology sre uses elements of software engineering it infrastructure web development and operations 3 to assist with reliability it is similar to devops as they both aim to improve the reliability and availability of deployed software systems history edit site reliability engineering originated at google with benjamin treynor sloss 4 5 who founded sre team in 2003 6 the concept expanded within the software development industry leading various companies to employ site reliability engineers 7 by march 2016 google had more than 1 000 site reliability engineers on staff 8 dedicated sre teams are common at larger web development companies 9 in middle sized and smaller companies devops teams sometimes perform sre as well 7 organizations that have adopted the concept include airbnb dropbox ibm 10 linkedin 11 netflix 8 and wikimedia 12 definition edit site reliability engineers sres are responsible for a combination of system availability latency performance efficiency change management monitoring emergency response and capacity planning 13 sres often have backgrounds in software engineering systems engineering and or system administration 14 the focuses of sre include automation system design and improvements to system resilience 14 sre is considered a specific implementation of devops 15 focusing specifically on building reliable systems whereas devops covers a broader scope of operations 16 17 18 despite having different focuses some companies have rebranded their operations teams to sre teams 7 principles and practices edit common definitions of the practices include but are not limited to 3 19 automation of repetitive tasks for cost effectiveness defining reliability goals to prevent endless effort design of systems with a goal to reduce risks to availability latency and efficiency observability the ability to ask arbitrary questions about a system without having to know ahead of time what to ask common definitions of the principles include but are not limited to toil management toil refers to manual repetitive automatable operational work 20 defining and measuring reliability goals slis slos and error budgets non abstract large scale systems design nalsd 21 with a focus on reliability designing for and implementing observability defining testing and running an incident management process capacity planning change and release management including ci cd chaos engineering deployment edit sre teams collaborate with other departments within organizations to guide the implementation of the mentioned principles below is an overview of common practices 22 kitchen sink edit kitchen sink 23 refers to the expansive and often unbounded scope of services and workflows that sre teams oversee unlike traditional roles with clearly defined boundaries sres are tasked with various responsibilities including system performance optimization incident management and automation this approach allows sres to address multiple challenges ensuring that systems run efficiently and evolve in response to changing demands and complexities infrastructure edit infrastructure sre teams focus on maintaining and improving the reliability of systems that support other teams workflows while they sometimes collaborate with platform engineering teams their primary responsibility is ensuring up time performance and efficiency platform teams on the other hand primarily develop the software and systems used across the organization while reliability is a goal for both platform teams prioritize creating and maintaining the tools and services used by internal stakeholders whereas infrastructure sre teams are tasked with ensuring those systems run smoothly and meet reliability standards tools edit sre teams utilize a variety of tools with the aim of measuring maintaining and enhancing system reliability these tools play a role in monitoring performance identifying issues and facilitating proactive maintenance for instance nagios core is commonly employed for system monitoring and alerting while prometheus software is frequently used for collecting and querying metrics in cloud native environments product or application edit sre teams dedicated to specific products or applications are common in large organizations 22 these teams are responsible for ensuring the reliability scalability and performance of key services in larger companies it s typical to have multiple sre teams each focusing on different products or applications ensuring that each area receives specialized attention to meet performance and availability targets embedded edit in an embedded model individual sres or small sre pairs are integrated within software engineering teams these sres collaborate with developers applying core sre principles such as automation monitoring and incident response directly to the software development lifecycle this approach aims to enhance reliability performance and collaboration between sres and developers consulting edit consulting sre teams specialize in advising organizations on the implementation of sre principles and practices typically composed of seasoned sres with a history across various implementations these teams provide insights and guidance for specific organizational needs when working directly with clients these sres are often referred to as customer reliability engineers 24 in large organizations that have adopted sre a hybrid model is common citation needed this model includes various implementations such as multiple product application sre teams dedicated to addressing the specific reliability needs of different products an infrastructure sre team may collaborate with a platform engineering group to achieve shared reliability goals for a unified platform that supports all products and applications industry edit since 2014 the usenix organization has hosted the annual srecon conference bringing together site reliability engineers from various industries this conference is a platform for professionals to share knowledge explore effective practices and discuss trends in site reliability engineering 25 see also edit chaos engineering cloud computing
