Retrospective ideas on KubeCon Europe 2022


I’m not going to lie. As I sit on a airplane flying away from Valencia, I confess to have been stunned by the dimensions of Kubecon Europe this 12 months. In my defence, I wasn’t alone the quantity of attendees appeared to take convention organisers and exhibitors abruptly, illustrated by the notable lack of water, (I used to be informed) t-shirts and (at varied factors) taxis.

Keynotes have been crammed to capability, and there was a real buzz from individuals which appeared to fall into two camps: the younger and funky, and the extra mature and soberly dressed.

My time at KubeCon Europe was largely spent in one-on-one conferences, analyst/press conferences and strolling the stands, so I can’t touch upon the engineering classes. Throughout the piece nonetheless, there was a real sense of Kubernetes now being in regards to the how, reasonably than the whether or not. For one motive or one other, firms have determined they wish to acquire the advantages of constructing and deploying distributed, container-based purposes.

Surprisingly sufficient, this wasn’t being seen as some magical sword that may slay the dragons of legacy programs and open the best way to digital transformation the kool-aid was as absent because the water. In the end, enterprises have accepted that, from an architectural standpoint and for purposes typically, the Kubernetes mannequin is nearly as good as any obtainable proper now, as a non-proprietary, well-supported open normal that they will get behind.

Virtualisation-based choices and platform stacks are too heavyweight; serverless architectures are extra relevant to particular use circumstances. So, if you wish to construct an utility and also you need it to be future-safe, the Kubernetes goal is the one to goal for.

Whether or not to undertake Kubernetes may be a achieved deal, however how you can undertake definitely shouldn’t be. The problem shouldn’t be with Kubernetes itself, however every part that should go round it to make ensuing purposes enterprise-ready.

For instance, they should function in compliance environments; knowledge must be managed, protected, and served into an atmosphere that doesn’t care an excessive amount of in regards to the state; integration instruments are required with exterior and legacy programs; improvement pipelines must be in place, strong and value-focused; IT Operations want a transparent view of what’s operating whereas a invoice of supplies, and the well being of particular person clusters; and catastrophe restoration is a should.

Kubernetes doesn’t do these items, opening the door to an ecosystem of resolution distributors and (usually CNCF-backed) open supply initiatives. I may drill into these areas Service Mesh, GitOps, orchestration, observability, and backup however the broader level is that they’re all evolving and coalescing across the want. As they enhance in functionality, obstacles to adoption cut back and the variety of potential use circumstances grows.

All of which places the trade at an fascinating juncture. It’s not that tooling isn’t prepared: organizations are already efficiently deploying purposes primarily based on Kubernetes. In lots of circumstances, nonetheless, they’re doing extra work than they want builders want insider information of goal environments, interfaces must be built-in reasonably than utilizing third-party APIs, higher-order administration tooling (similar to AIOps) needs to be custom-deployed reasonably than recognising the norms of Kubernetes operations.

Options do exist, however they are typically coming from comparatively new distributors which might be function reasonably than platform gamers, which means that end-user organisations have to decide on their companions correctly, then construct and preserve improvement and administration platforms themselves reasonably than utilizing pre-integrated instruments from a singe vendor.

None of this can be a drawback per se, nevertheless it does create overheads for adopters, even when they acquire earlier advantages from adopting the Kubernetes mannequin. The worth of first-mover benefit needs to be weighed towards that of investing effort and time within the present state of tooling: as a journey firm as soon as informed me, “we wish to be the world’s finest journey website, not the world’s finest platform engineers.”

So, Kubernetes could also be inevitable, however equally, it’s going to change into easier, enabling organisations to use the structure to an more and more broad set of eventualities. For organisations but to make the step in direction of Kubernetes, now should still be an excellent time to run a proof of idea although in some methods, that sip has sailed maybe focus the PoC on what it means for working practices and buildings, reasonably than figuring out whether or not the ideas work in any respect.

In the meantime and maybe most significantly, now’s an excellent second for organisations to search for what eventualities Kubernetes works finest “out of the field”, working with suppliers and reviewing architectural patterns to ship confirmed outcomes towards particular, high-value wants these are more likely to be by trade and by the area (I may dig into this, however did I point out that I’m sitting on a airplane? 😉 ).

KubeCon Europe abstract – Kubernetes may be a achieved deal, however that doesn’t imply it needs to be adopted wholesale earlier than a number of the peripheral element is ironed out.
