Retrospective thoughts 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 taken aback by the scale of Kubecon Europe this year. In my defence, I was not by itself the quantity of attendees appeared to get conference organisers and exhibitors by surprise, illustrated by the noteworthy lack of drinking water, (I was informed) t-shirts and (at several points) taxis.

Keynotes were filled to ability, and there was a authentic buzz from participants which appeared to slide into two camps: the younger and cool, and the far more mature and soberly dressed.

My time was mostly invested in 1-on-a single meetings, analyst/press conferences and walking the stands, so I simply cannot comment on the engineering periods. Throughout the piece nevertheless, there was a legitimate sense of Kubernetes now currently being about the how, instead than the regardless of whether. For one cause or a different, businesses have made the decision they want to achieve the rewards of constructing and deploying distributed, container-centered purposes.

Surprisingly ample, this wasn’t getting observed as some magical sword that can slay the dragons of legacy devices and open the way to electronic transformation the kool-aid was as absent as the water. Ultimately, enterprises have accepted that, from an architectural standpoint and for purposes in typical, the Kubernetes design is as good as any accessible right now, as a non-proprietary, well-supported open up common that they can get powering.

Virtualisation-based options and platform stacks are also heavyweight serverless architectures are additional applicable to precise use conditions. So, if you want to build an software and you want it to be long term-safe and sound, the Kubernetes goal is the one particular to goal for.

Whether or not to adopt Kubernetes might be a completed offer, but how to adopt surely is not. The problem is not with Kubernetes itself, but every thing that desires to go all around it to make resulting programs business-prepared.

For instance, they need to have to operate in compliance environments information demands to be managed, safeguarded, and served into an surroundings that doesn’t care far too considerably about the condition integration equipment are required with external and legacy devices growth pipelines require to be in place, robust and benefit-focused IT Functions need to have a distinct view of what’s jogging whereas a bill of components, and the overall health of particular person clusters and catastrophe restoration is a have to.

Kubernetes doesn’t do these things, opening the doorway to an ecosystem of resolution suppliers and (usually CNCF-backed) open up source projects. I could drill into these locations Company Mesh, GitOps, orchestration, observability, and backup but the broader level is that they are all evolving and coalescing close to the need to have. As they raise in ability, barriers to adoption lessen and the range of probable use circumstances grows.

All of which places the business at an interesting juncture. It’s not that tooling is not prepared: corporations are now productively deploying applications primarily based on Kubernetes. In numerous circumstances, however, they are carrying out more get the job done than they need to have builders need to have insider awareness of focus on environments, interfaces require to be integrated rather than applying third-celebration APIs, higher-buy administration tooling (this kind of as AIOps) has to be custom made-deployed somewhat than recognising the norms of Kubernetes operations.

Solutions do exist, but they are likely to be coming from comparatively new vendors that are element alternatively than system gamers, which means that stop-consumer organisations have to opt for their companions wisely, then construct and maintain enhancement and administration platforms on their own alternatively than using pre-integrated applications from a singe seller.

None of this is a difficulty for every se, but it does generate overheads for adopters, even if they attain before gains from adopting the Kubernetes product. The benefit of very first-mover benefit has to be weighed versus that of investing time and effort and hard work in the current condition of tooling: as a travel enterprise at the time explained to me, “we want to be the world’s most effective travel web site, not the world’s most effective system engineers.”

So, Kubernetes may perhaps be inescapable, but similarly, it will turn into more simple, enabling organisations to implement the architecture to an more and more broad established of eventualities. For organisations nonetheless to make the phase toward Kubernetes, now might nonetheless be a fantastic time to operate a evidence of notion even though in some means, that sip has sailed probably focus the PoC on what it suggests for operating practices and buildings, somewhat than deciding irrespective of whether the concepts get the job done at all.

Meanwhile and probably most importantly, now is a incredibly good instant for organisations to glimpse for what situations Kubernetes performs best “out of the box”, performing with providers and examining architectural patterns to supply proven success towards particular, high-worth requirements these are probable to be by business and by the domain (I could dig into this, but did I mention that I’m sitting on a plane? 😉 ).

Kubernetes may be a carried out offer, but that doesn’t mean it ought to be adopted wholesale right before some of the peripheral depth is ironed out.
