Overview
Go helps enterprises automate and scale
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.
Site Reliability Engineering (SRE) was born at Google to make the company’s “large-scale sites more reliable, efficient,
and scalable,”
writes Silvia Fressard
, 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
“
empowers software developers
to own the ongoing daily operation
of their applications in production.”
Go serves both siblings, DevOps and SRE, from its fast build times and lean syntax to its security and reliability support. Go’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.
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.
Key Benefits
Easily build small scripts with Go’s robust standard library and static typing
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.
Quickly deploy CLIs with Go’s fast build times
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.
Scale and maintain larger applications with Go’s low memory footprint and doc generator
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.
