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 amount of attendees appeared to take convention organisers and exhibitors unexpectedly, illustrated by the notable lack of water, (I used to be instructed) t-shirts and (at varied factors) taxis.

Keynotes had been stuffed 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 concerning the how, quite than the whether or not. For one motive or one other, corporations have determined they need to acquire the advantages of constructing and deploying distributed, container-based purposes.

Unusually sufficient, this wasn’t being seen as some magical sword that may slay the dragons of legacy techniques and open the best way to digital transformation the kool-aid was as absent because the water. Finally, enterprises have accepted that, from an architectural standpoint and for purposes basically, 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 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 may be a achieved deal, however undertake definitely will not be. The problem will not be with Kubernetes itself, however the whole lot 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 surroundings that doesn’t care an excessive amount of concerning the state; integration instruments are required with exterior and legacy techniques; improvement pipelines should 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 these items, opening the door to an ecosystem of resolution distributors and (typically CNCF-backed) open supply tasks. I might 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 improve in functionality, limitations to adoption scale back and the variety of potential use circumstances 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 based mostly on Kubernetes. In lots of circumstances, nonetheless, they’re doing extra work than they want builders want insider information of goal environments, interfaces should be built-in quite than utilizing third-party APIs, higher-order administration tooling (equivalent to AIOps) needs to be custom-deployed quite than recognising the norms of Kubernetes operations.

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

None of this can be a downside per se, but it surely 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 instructed me, “we need to be the world’s finest journey web site, not the world’s finest platform engineers.”

So, Kubernetes could also be inevitable, however equally, it’s going to turn into less complicated, enabling organisations to use the structure to an more and more broad set of situations. For organisations but to make the step in the direction of Kubernetes, now should 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, quite than figuring out whether or not the ideas work in any respect.

In the meantime and maybe most significantly, now could be an excellent second for organisations to search for what situations 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 business and by the area (I might 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 ought to be adopted wholesale earlier than among the peripheral element is ironed out.
