Engineers are nice at making laborious issues attainable. Then repeatable. Then automatable. Then run on their very own. Software growth has repeated this cycle time and again. We construct a brand new functionality; we make it simpler to repeat with scripts, we let it run by itself with fastened features, after which we summary it into code the place we now not fear or give it some thought.

Today we construct workflows decoupled from the applied sciences themselves, with code that’s expressive and declarative, primarily based on finish targets and desired states.

But on the subject of the way in which we function and scale the underlying infrastructures that energy our software program, we glance extra like a Formula One pit crew — a high-performance staff of specialists that want to repeatedly triage, tune, regulate, and restore.

Infrastructure at our fingertips

The cloud has remodeled how we construct software program. With a single API name, you’ll be able to spin up extra compute sources than existed in all the final decade mixed. Developers went from desirous about bodily machines to dwelling in a world of community, compute, and storage as digital sources. These sources have led to a era of “cloudified” (serverless) providers and “containers” (self-contained runtime environments) for nearly each a part of the developer stack, lowering operational price, complexity, and engineering lead occasions.

And there’s a lot to love about this new world of containers and serverless. Powerful Open Source and business tasks resembling Git, Jenkins, Cloudflare, Terraform, Puppet/Chef/Ansible, and Kubernetes have dramatically improved how we deploy infrastructure, functions, and handle workflows. (Disclosure: My agency is an investor in Cloudflare.)

That’s till you have to begin stitching all of them collectively. At that time, you enter an unwieldy sprawl of static configurations, scripts, and recordsdata.

Configuration sprawl

If this all sounds overly advanced, that’s as a result of it’s. Before software program is even written, it may take hours to configure and deploy the underlying cluster or workflow. Workflows are constructed on the again of static scripts and configuration recordsdata, missing versioning or testability. Scale and efficiency require guide tuning. Configuration recordsdata and documentation exit of sync sooner than DevOps can sustain. Triaging errors and failures requires hours of guide tracing. Best practices and patterns are laborious to implement. With fixed operator intervention wanted to maintain all of it operating, the groups constructing and sustaining infrastructure are sometimes bigger than the groups constructing the providers or functions on prime of it.

This complexity is changing into magnified in a COVID-19 world as corporations cope with impacted working plans and distributed workforces. With restricted sources and rising demand load, unbundling the complexity and eliminating the guide and repetitive duties that plague DevOps and engineering groups has by no means been extra necessary.

We’ve been caught with instruments and configurations that fixate on the underlying applied sciences, not on workflows describing finish targets and desired states.

This presents us with a chance to construct a brand new era of instruments and workflows that can programmatically function infrastructure the identical means we use code to construct our software program.

Everything as code

The concept of “everything as code” (EaC) is rising throughout every layer of the stack. It entails writing infrastructure as software program, the place the whole lot is expressed with code.

With code, you’ll be able to describe the top outcome or the collection of steps to take. It’s declarative and expressive. EaC introduces a world the place our infrastructures, workflows, and providers begin to display the mature, programmatic, and resilient patterns we’re used to:

  • Version managed and immutable
  • Maintainable, testable, and collaborative
  • Modular, composable, and separate
  • Auto-scalable and resource-pool dynamically
  • Predictable and constant
  • Linters and static evaluation to implement consistency
  • Graceful self-healing and failovers
  • No want for fixed operator intervention
  • Secure and upgradable

EaC adjustments the main focus from guide, repetitive duties to workflows primarily based on finish targets and desired states. Bringing how we handle infrastructure nearer to the maturity of how we construct software program.

Companies like HashiCorp, Cloudflare, Confluent, Amazon, Puppet Labs, Astronomer, and extra, together with a thriving open supply neighborhood, are basically altering the whole lot from how we deploy and function servers, environments, containers, pipelines, and extra, as code.

EaC represents a serious shift and catch-up. The cloud unlocked new capabilities to construct software program sooner, cheaper, and higher. The velocity of recent capabilities grew sooner than we might think about. The sooner we adopted them, the extra the software program and instruments to function them have been buckling on the knees. Our legacy workflows can now not sustain with the pace of the cloud. Now is the time to catch up and construct a brand new wave of instruments, capturing the whole lot as code.
