Can Kubernetes assist resolve automation challenges?

I began my automation journey once I adopted Gentoo Linux as my main working system in 2002. Twenty years later, automation just isn’t but a completed deal. When I meet with prospects and companions, they share automation wins inside groups, however in addition they describe the challenges to reaching related success at an organizational degree.

Most IT organizations have the flexibility to provision a digital machine finish to finish, lowering what was a four-week lead time to only 5 minutes. That degree of automation is itself a posh workflow, requiring networking (IP tackle administration, DNS, proxy, networking zones, and so forth), identification entry administration, hypervisor, storage, backup, updating the working system, making use of the most recent configuration information, monitoring, safety and hardening, and compliance benchmarking. Wow!

It’s not straightforward to deal with the enterprise want for top velocity, scaling, and on-demand automation. For occasion, take into account the traditional webshop or an internet authorities service to file tax returns. The workload has well-defined peaks that should be absorbed.

A standard strategy for dealing with such a load is having an outsized server farm, prepared for use by a specialised crew of IT professionals, monitoring the seasonal inflow of consumers or residents. Everybody needs a just-in-time deployment of a whole stack. They need infrastructure working workloads inside the context of a hybrid cloud situation, utilizing the mannequin of “build-consume-trash” to optimize prices whereas benefiting from infinite elasticity.

In different phrases, all people needs the utopian “cloud experience.”

Can the cloud actually ship?

All just isn’t misplaced, thanks primarily to the best way Kubernetes has been designed. The exponential adoption of Kubernetes fuels innovation, displacing customary legacy practices for managing platforms and purposes. Kubernetes requires the usage of Everything-as-Code (EaC) to outline the specified state of all sources, from easy compute nodes to TLS certificates. Kubernetes compels the usage of three main design constructs:

  • An ordinary interface to cut back integration friction between inner and exterior elements
  • An API-first and API-only strategy to standardize the CRUD (Create, Read, Update, Delete) operations of all its elements
  • Use of YAML as a typical language to outline all desired states of those elements in a easy and readable means

These three key elements are basically the identical necessities for selecting an automation platform, not less than if you wish to ease adoption by cross-functional groups. This additionally blurs the separation of duties between groups, serving to to enhance collaboration throughout silos, which is an effective factor!

As a matter of reality, prospects and companions adopting Kubernetes are ramping as much as a state of hyper-automation. Kubernetes organically drives groups to undertake a number of DevOps foundations and practices—like EaC, version control with Git, peer opinions, documentation as code—and encourages cross-functional collaboration. These practices assist mature a crew’s automation expertise, and so they assist a crew get an excellent begin in GitOps and CI/CD pipelines coping with each software lifecycle and infrastructure.

Making automation a actuality

You learn that proper! The total stack for advanced methods like a webshop or authorities reporting could be outlined in clear, comprehensible, common phrases that may be executed on any on-prem or cloud supplier. An autoscaler with customized metrics could be outlined to set off a just-in-time deployment of your required stack to deal with the inflow of consumers or residents throughout seasonal peaks. When metrics are again to regular, and cloud compute sources haven’t got a purpose to exist anymore, you trash them and return to common operations, with a set of core belongings on-prem taking up the enterprise till the following surge.

The hen and the egg paradox

Considering Kubernetes and cloud-native patterns, automation is a should. But it raises an essential query: Can a company undertake Kubernetes earlier than addressing the automation technique?

It might sound that beginning with Kubernetes may encourage higher automation, however that is not a foregone conclusion. A instrument just isn’t a solution to the issue of expertise, practices, and tradition. However, a well-designed platform is usually a catalyst for studying, change, and cross-functional collaboration inside an IT group.

Get began with Kubernetes

Even for those who really feel you missed the automation practice, do not be afraid to start out with Kubernetes on a simple, uncomplicated stack. Embrace the simplicity of this improbable orchestrator and iterate with extra advanced wants as soon as you’ve got mastered the initial steps.
