Cloud Foundry is not capitulating on its dream by embracing Kubernetes—it is fulfilling that dream.

Cloud Foundry could have its issues similar to another group, however arguably, its choice to embrace Kubernetes is not considered one of them, regardless of recommendations on the contrary. Actually, as Cloud Foundry Basis govt director Abby Kearns put it, “Our imaginative and prescient is to be the most effective cloud native platform for builders,” regardless of the underlying applied sciences.

The loss of life of a disco dancer
Sarcastically, whereas criticizing Pivotal for “hyper advertising” the Cloud Foundry platform, Rishidot analyst Krishnan Subramanian does a bit hyper advertising himself. On the eve of a well-attended Cloud Foundry occasion, Subramanian wrote a eulogy “on the ‘demise’ of Cloud Foundry.” I believed I had missed a significant announcement—that the undertaking had someway folded. I scoured the web, on the lookout for information of this “demise.”
To no avail.
Sure, I had buddies pinging me to inform me that Pivotal, the corporate behind Cloud Foundry (now housed in its personal basis), was struggling. I checked out its financials: Narrowing losses and elevated revenues. The inventory worth is not at its peak, but it surely has been transferring up constantly during the last six months. LinkedIn exhibits that the whole head depend has declined 14% over two years, and down three% during the last six months. Not setting the world on fireplace, maybe, however not useless, both. (And, as Start co-founder Brian Leroux has famous of Pivotal’s $5 billion market cap: “Hope I fail our a—— right into a $5 billion area of interest enterprise! lmao.”)
And that is Pivotal, not Cloud Foundry. So when did Cloud Foundry die?
Digging into Subramanian’s put up, it turns into clear that he is utilizing “demise” in a really specific method. Noting that Cloud Foundry’s authentic container format (Backyard, most just lately) and orchestration engine (Diego) had each been changed by trade requirements (Docker and Kubernetes), he concludes: “As soon as you’re taking the container runtime and container orchestration out of the equation, no matter stays from the unique Cloud Foundry platform has very restricted relevance.” Or, in his rendering, is useless.
Once I requested for clarification, he obliged: “There isn’t any magical expertise or effectivity supplied by Cloud Foundry which isn’t already accessible in Kubernetes ecosystem. This announcement solely helps current Cloud Foundry clients to make use of Kubernetes as an alternative of Diego. In any other case, Cloud Foundry as an idea is useless.”
Is it, although?
Effectively, it occurs lots round right here
With one caveat (which I am going to come again to), for a corporation like Pivotal (or Crimson Hat or…identify your enterprise vendor) it actually (actually) would not matter what the underlying applied sciences are. If Crimson Hat powered OpenShift with magical hamsters however clients obtained the size and ease-of-use they require, nobody (besides perhaps PETA) would thoughts. In like method, the truth that Cloud Foundry has been altering the applied sciences that energy its platform is immaterial to buyer success with that platform.

As Kearns put it to me, “For the final couple of days, I have been having conversations with customers at our summit, customers who’re operating tens of hundreds of purposes on Cloud Foundry, and plan to extend these numbers.” When Cloud Foundry started, it supplied performance that Kubernetes could not match. That has since modified, which is why Pivotal engineer Oleksandr Slynko may write in October 2017 that Kubernetes would by no means substitute Diego after which in Could 2018 he reversed his adamant assertion to say “Positive it will probably.” Pivotal, and Cloud Foundry, needed to evolve to embrace what the market had chosen.
That call, nevertheless, is pushed by clients. As Kearns famous, “Having a steady platform is of the utmost significance. Being proper on the expertise hype cycle will not be of the utmost significance.” As Kubernetes matured and solidified trade assist, it grew to become the apparent reply to Cloud Foundry’s container orchestration wants. Over time, Kearns went on, that may properly change, with Cloud Foundry dedicated to swapping out applied sciences to maintain with its core mission: “Our imaginative and prescient is to be the most effective cloud native platform for builders. You need to by no means financial institution on one particular, tiny expertise to be the tip sport. That is not the tip sport. The tip sport is to have a platform that enables clients to construct, run, and scale purposes.”
Or, as Pivotal vice chairman Richard Seroter mentioned, “Kubernetes is nice. That is why it’s going to be a part of Cloud Foundry, as are a dozen different nice open supply software program initiatives we have swapped in over time. However the worth of automating the trail to manufacturing in a SINGLE platform is effective by itself. And folks pay for packaging of that, versus DIY.”
Which brings us to the caveat I referenced above.
Should you suppose peace is a typical objective
There may be worth in embracing an trade development first, and serving to to form it, as Pivotal/Cloud Foundry competitor Crimson Hat/OpenShift has finished with Kubernetes. Again in 2015, Crimson Hat opted to skip becoming a member of the Cloud Foundry Basis, and as an alternative doubled down on Docker and, later, Kubernetes. Writing on the time, Crimson Hat’s Joe Fernandes highlighted the significance of this alternative:
With Linux containers on the core of many trendy cloud software platforms, we felt it could be a misplaced alternative to not embrace an rising container customary. Crimson Hat has at all times labored to drive upstream requirements within the Linux group, to assist keep away from expertise fragmentation, and with containers we see the necessity for the same strategy. Requirements for container codecs (together with packaging, APIs, index metadata) additionally allow us to collaborate with distributors like Google, Microsoft, IBM and others who’ve equally determined to assist Docker.
Related motivations underlined the choice to go along with Kubernetes:
Given Google’s deep experience in container expertise and managing what is probably going the most important containerized datacenter infrastructure in existence, we felt that standardizing on Kubernetes can be the proper alternative for OpenShift customers. As we speak Crimson Hat is contributing extensively to Kubernetes, and dealing with the group to deliver these capabilities to [Red Hat] clients…. And in contrast to Cloud Foundry Diego, we aren’t investing in an OpenShift-specific container orchestration answer, however one that’s being supported by quite a lot of distributors together with Microsoft, IBM, Mesosphere, CoreOS and extra.
Cloud Foundry ultimately reached the identical conclusion, however there may be worth for Crimson Hat in having such a deep footprint within the open supply communities round Docker and Kubernetes. Whereas Crimson Hat would not management both group, it has “purchased” itself affect with the code it has contributed. This places it in a stronger place to assist these still-emerging trade requirements.
So, is Cloud Foundry “useless?” Nope. Not even shut. However will it’s that rather more alive if it, sooner or later, helps to drive trade requirements like Kubernetes, as Crimson Hat has finished, relatively than come to the social gathering belatedly? Sure. Even so, full credit score must be given to Pivotal for reaching the proper conclusion in any respect: It is exhausting to vary expertise route after massive investments have been made. They’ve finished this greater than as soon as, and that is a credit score to its buyer focus.
