Retrospective ideas on KubeCon Europe 2022


I’m not going to lie. As I sit on a aircraft flying away from Valencia, I confess to have been greatly surprised by the size of Kubecon Europe this 12 months. In my defence, I wasn’t alone the amount of attendees appeared to take convention organisers and exhibitors unexpectedly, illustrated by the notable lack of water, (I used to be advised) 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 periods. Throughout the piece nevertheless, there was a real sense of Kubernetes now being concerning the how, reasonably than the whether or not. For one motive or one other, corporations 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 way in which to digital transformation the kool-aid was as absent because the water. Finally, enterprises have accepted that, from an architectural standpoint and for purposes on the whole, the Kubernetes mannequin is pretty much as good as any obtainable proper now, as a non-proprietary, well-supported open commonplace that they will get behind.

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

Whether or not to undertake Kubernetes could be a carried out deal, however undertake definitely will not be. The problem will not be with Kubernetes itself, however every little thing that should go round it to make ensuing purposes enterprise-ready.

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

Kubernetes doesn’t do this stuff, opening the door to an ecosystem of resolution distributors and (typically CNCF-backed) open supply tasks. 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, limitations to adoption cut back and the variety of potential use instances grows.

All of which places the business 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 instances, nevertheless, they’re doing extra work than they want builders want insider information of goal environments, interfaces have to be built-in reasonably than utilizing third-party APIs, higher-order administration tooling (similar to AIOps) must 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 characteristic reasonably than platform gamers, that means that end-user organisations have to decide on their companions correctly, then construct and keep improvement and administration platforms themselves reasonably than utilizing pre-integrated instruments from a singe vendor.

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

So, Kubernetes could also be inevitable, however equally, it is going to develop into less complicated, enabling organisations to use the structure to an more and more broad set of eventualities. For organisations but to make the step in the 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 greatest “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 business and by the area (I may dig into this, however did I point out that I’m sitting on a aircraft? 😉 ).

KubeCon Europe abstract – Kubernetes could be a carried out deal, however that doesn’t imply it must be adopted wholesale earlier than among the peripheral element is ironed out.
