Cloud-native platforms have set the criteria for development and deploying tool. They’ve enabled enterprises that didn’t exist twelve years in the past to achieve extremely aggressive markets. Cloud Foundry (CF), the open supply cloud utility platform, has been a driver in that luck, making it imaginable for enterprises to construct, take a look at, deploy and scale tool considerably sooner.
The perpetual problem of making sure cloud-native applied sciences are used successfully and securely is an ongoing struggle, and organizations will at all times stay a cautious eye on expanding profitability. This has observed the emergence of Kubernetes with the intention to briefly deploy and organize containerized apps in tool building and manufacturing and raised questions referring to CF’s long term.
The questions have grow to be extra pressing since VMware closed Pivotal Internet Products and services (PWS), its fully-managed CF, in January 2021. Was once this a sign that Kubernetes had “received”? Did this imply the “finish” of CF? Whilst PWS shoppers moved quickly to discover a alternative, shoppers operating their very own CF installations had been left unsure.

So is CF going to vanish? Now not precisely as a result of at its core, Cloud Foundry is an settlement between platform and developer, and this revel in remains to be in top call for. CF gives to bundle, time table, and run a developer’s programs in the event that they abide via the 12-factor app method. This system covers the whole lot from the codebase and dependencies to logs and admin processes. It guarantees that the appliance layer on most sensible of the platform can scale and thrive in a cloud setting. On the very least, it gives a unified utility structure that works the similar throughout more than one programming languages.
This settlement sees cloud-native programs run predictably and reliably with a standardized manner. Different advantages of the 12-factor manner are written in one of the most regulations:
- “A 12-factor utility crashes (or exits gracefully) if it can’t do its activity”
- “A 12-factor utility does now not depend at the implicit life of any machine gear.”
The attributes those regulations create are what make Kubernetes so common, reminiscent of concurrency, disposability, and modularity, however this isn’t sudden as Kubernetes could also be a cloud-native platform and is guided via the similar regulations as CF.
CF’s long term is in converting and in search of to profit from Kubernetes. As RedMonk analyst Stephen O’Grady commented ultimate yr, the longer term for Cloud Foundry is the way it “can give abstractions above and round Kubernetes to fortify the total developer and operator revel in.”
Spotting that CF is extra a freelance than a unique platform, there are a number of programs that exist nowadays in quite a lot of building phases that apply CF’s platform-developer settlement. The primary is “conventional” CF, the VM-based Cloud Foundry. That is deployed on VMs via BOSH, a digital device orchestrator for deploying, scaling, and keeping up apps on most sensible of VMs from many various cloud suppliers.
Subsequent is KubeCF, which containerizes BOSH releases for Kubernetes. This legitimate Cloud Foundry Basis challenge permits the intake of the similar BOSH releases that different CF groups use whilst supplying probably the most strong and trustworthy CF implementation for the preferred container orchestrator.
There’s any other legitimate CF challenge enthusiastic about Kubernetes referred to as cf-for-k8s. This challenge takes a Kubernetes-native manner involving an enormous trade to each implementation and structure. This challenge is at an previous beta level and taking a look to send Open Container Photographs as a substitute of BOSH releases. Moreover, as Kubernetes has a container runtime, CF’s Diego used to be got rid of, and gorouter has been changed with Istio and Envoy.
Because of the adjustments the cf-for-k8s challenge has made to CF parts, the code the CF challenge workforce has to care for has been a great deal lowered. We additionally be expecting that, because the artifacts that KubeCF is dependent upon forestall being launched, KubeCF will steadily undertake the production-viable parts of cf-for k8s over the years.
The general choice, evolved via Google, is extra of an outlier, despite the fact that it has the prospective to be disruptive. It’s referred to as kf and is a client-side reimplementation of the cf instrument for Kubernetes (see what they did there?). Google is treating this as a migration instrument, enabling a consumer to move from deploying supply code to a CF immediately to a GCP Kubernetes cluster on most sensible of GKE, nevertheless it already helps most of the maximum regularly used instructions and flags. This can be a proprietary manner enthusiastic about Google merchandise. Nonetheless, the speculation of deploying and managing programs on a Kubernetes cluster with a easy shell alias is prone to have an attraction past Google.
As extra innovation happens the place some great benefits of each CF and Kubernetes are leveraged, we stay extremely hopeful that CF on Kubernetes will imply that mid-market corporations, and now not simply massive enterprises, will have the benefit of the industry benefits and revel in that CF gives.
Whilst it’s obvious that CF is not likely to vanish, it’s crucial to grasp its persevered industry price as smartly.
CF gives a consumer revel in that operator’s love
From a developer and operator standpoint, the advantages are interesting. Cloud Foundry sits above the infrastructure (IaaS) layer, offering an abstraction of infrastructure services and products, and simplifying operations thru a unmarried platform. The best way CF deploys apps with its cf push revel in used to be famously described within the haiku: “Here’s my supply code. Run it at the cloud for me; I don’t care how.” It’s an revel in that operators don’t wish to lose, as they don’t have to fret about things like provider discovery or the place apps are deployed.
CF is open supply and will scale back licensing prices
When taking into account sooner tactics to marketplace, Open Supply CF (OCF) can considerably scale back IT prices. As open supply tool is loose to make use of, it reduces the prices related to pricey license charges for industrial per-app circumstances. For organizations the use of a “CF-as-a-Carrier” cloud-based choice, it is usually a possibility to ditch over the top infrastructure footprints and scrap seven-digit beef up contracts. OCF most often calls for a bigger operations workforce to permit for code contributions to OCF, however in the long run there are substantial charge financial savings to be made.
CF gives adaptability thru automation for greater organizations
CF additionally delivers the nimbleness of CI/CD and DevOps to a lot greater organizations. So whilst CF can transfer an app briefly into manufacturing, it enabled, as an example, a monetary provider to patch ZombieLoad assault in not up to seven days with a setup of a couple of hundred Diego cells serving as much as 40,000 apps. This challenge used to be additionally completed with out affecting the app groups or the operating programs.
CF’s opinionated design reduces complexity, however nonetheless lets in for personalization
CF gets rid of complexity and ache from the operator via being opinionated, however the assumptions and optimizations that it makes don’t save you it from being configurable and extendable. Its extensibility doesn’t permit for CF’s nature to switch, however it will probably permit for actual customization. As an example, we evolved a “BOSH Splitter” instrument that intended a buyer may just unfold their repairs duties, reminiscent of scheduling stemcell (VM symbol) rotations, throughout more than one days and small home windows as a substitute of a unmarried 2-day deployment.
CF has had a “multicloud-native” design from the outset and avoids dealer lock-in
Making an allowance for that now not many companies had been fascinated by multicloud when CF used to be designed as an open platform, CF can counter present dealer lock-in considerations rather well. As an open platform, CF abstracts compute assets to create a regular strategy to deploy services and products and programs throughout other cloud suppliers. For enterprises the use of CF and adopting hybrid and multicloud approaches, we all know that CF’s abstraction has allowed them to barter higher provider contracts.
CF establishes a basis for agile app migrations
Whilst CF is structured and opinionated, for corporations taking into account their cloud-native adventure, CF can allow high-quality app transformations as soon as the groundwork is finished. In our personal revel in, we’ve migrated over 1,132 non-production and manufacturing apps for an agricultural biotech endeavor with out slowing or requiring the dev workforce’s consideration. This challenge concerned solving all manifests and 271 Java pipelines and completed with out preventing workflow in any respect.
In a industry international that calls for speeded up trade, Cloud Foundry is incessantly evolving and responding to the calls for of the tool construct, take a look at, deploy, and scale cycle. This now not most effective method sooner go-to-market however keeping up the significance of the improvement comments cycle. It’s now not most effective predictability and reliability but in addition extensibility. It’s now not simply ease of use at scale; it’s cost-effective answers. Cloud Foundry used to be designed to summary complexity, so it must understand how to switch itself with out you noticing the trade.
