<h3 id="go-helps-enterprises-automate-and-scale">Go helps enterprises automate and scale</h3>
<p>Development Operations (DevOps) teams help engineering organizations automate tasks and improve their continuous
integration and continuous delivery and deployment (CI/CD) process. DevOps can topple developmental silos and implement
tooling and automation to enhance software development, deployment, and support.</p>
<p>Site Reliability Engineering (SRE) was born at Google to make the company’s “large-scale sites more reliable, efficient,
and scalable,”<a href="https://opensource.com/article/18/10/what-site-reliability-engineer" rel="noreferrer" target="_blank"> writes Silvia Fressard</a>, an
independent DevOps consultant. “And the practices they developed responded so well to Google’s needs that other big tech
companies, such as Amazon and Netflix, also adopted them.” SRE requires a mix of development and operations skills, and
“<a href="https://stackify.com/site-reliability-engineering/" rel="noreferrer" target="_blank">empowers software developers</a> to own the ongoing daily operation
of their applications in production.”</p>
<p>Go serves both siblings, DevOps and SRE, from its fast build times and lean syntax to its security and reliability support. Go&rsquo;s concurrency and networking features also make it ideal for tools that manage cloud deployment—readily supporting automation while
scaling for speed and code maintainability as development infrastructure grows over time.</p>
<p>DevOps/SRE teams write software ranging from small scripts, to command-line interfaces (CLI), to complex automation and services, and Go’s feature set has benefits for every situation.</p>
<h2 id="key-benefits" class="sectionHeading">Key Benefits</h2>
<h3 id="easily-build-small-scripts-with-gos-robust-standard-library-and-static-typing">Easily build small scripts with Go’s robust standard library and static typing</h3>
<p>Go’s fast build and startup times. Go’s extensive standard library—including packages for
common needs like HTTP, file I/O, time, regular expressions, exec, and JSON/CSV formats—lets DevOps/SREs get right into their business logic. Plus, Go’s static type system and explicit error handling make even small scripts more robust.</p>
<h3 id="quickly-deploy-clis-with-gos-fast-build-times">Quickly deploy CLIs with Go’s fast build times</h3>
<p>Every site reliability engineer has written “one-time use” scripts that turned into CLIs used by dozens of other engineers every day. And small deployment automation scripts turn into rollout management services. With Go, DevOps/SREs are in a great position to be successful when software scope inevitably creeps. Starting with Go puts you in a great position to be successful when that happens.</p>
<h3 id="scale-and-maintain-larger-applications-with-gos-low-memory-footprint-and-doc-generator">Scale and maintain larger applications with Go’s low memory footprint and doc generator</h3>
<p>Go’s garbage collector means DevOps/SRE teams don’t have to worry about memory management. And Go’s automatic documentation generator (godoc) makes code self-documenting–lowering maintenance overhead and establishing best practices from the get-go.</p>
