CloudFoundry is a free, open source cloud computing platform supported by the non-profit CloudFoundry. It is not tied to any particular cloud service, but can be self-hosted or run on any cloud service preferred.

Developed by Rancher Labs and now from SUSE, Rancher is open-source software that enables organizations to deploy and manage Kubernetes at scale, on any infrastructure across the data center, cloud, branch offices, and the network edge. Rancher centrally manages Kubernetes clusters across the organization in order to ensure security and accelerate transformation. Rancher is also available hosted. Hosted Rancher is a fully managed Rancher control plane - presented as the fastest, most cost…
SUSE Rancher as a management tool becomes useful on a larger scale. Small deployments not so much. If someone also requires Kubernetes capacity or storage, Rancher is an excellent choice. Also, without Kubernetes' skills, it is unlikely that Rancher deployment is going to be a success. Then again if someone else is managing your Kubernetes capacity, setting up the software's capacity will yield greater control. Rancher is not a very integrated solution similar to others in the market.
Support for Orgs and Spaces that allow for managing users and deployables within a large organization.
Easy deployment, deploying code is as simple as executing single line from CLI, thanks to build-packs.
Solid and rich CLI, that allows for various operations on the instance.
Isolated Virtual Machines called Droplets, that provide clean run time environment for the code. This used to be a problem with Weblogic and other application servers, where multiple applications are run on the same cluster and they share resources.
SSH capability for the droplet (isolated VM's are called droplets), that allows for real time viewing of the App code while the application is running.
Support for multiple languages, thanks to build-packs.
Support for horizontal scaling, scaling an instance horizontally is a breeze.
Support for configuring environment variable using the service bindings.
Supports memory and disk space limit allocation for individual applications.
Supports API's as well as workers (processes without endpoints)
Supports blue-green deployment with minimal down time
Does not support stateful containers and that would be a nice to have.
Supports showing logs, but does not persist the logs anywhere. This makes relying on Cloud Foundry's logs very unreliable. The logs have to be persisted using other third party tools like Elk and Kibana.
No possibility to snapshot Projects. You can snapshot and restore the whole Kubernetes cluster, but not a Project or Namespace. For this, you have to use external tools.
You cannot detach the Rancher-created Kubernetes clusters from Rancher management.
The software is straightforward to use and easy enough to get started with. Then complex use cases require a lot of attention not because of SUSE Rancher but because of Kubernetes and cloud native in general.
The documentation is quite complete and there is a very active community that is willing to collaborate and answer questions for those who are just starting out.
While Docker shines in providing support for volumes and stateful instances, Cloud foundry shines in providing support for deploying stateless services. Heroku shines in integrating with Git and using commits to git as hooks to trigger deployments right from the command line. But it does not provide on-premise solution that Cloud foundry provides.
As we use only AWS EKS Clusters originally we were using the AWS Console and CLI but that is too limited in scope. Also, we were using AWS IAM roles to provide access to users but that was lots of extra work to have them integrated into SSO while on Rancher we have just connected our GitHub login with the Alfresco organization and that uses, in turn, Okta for SSO so provisioning for access is automatic for any developer who has been assigned to GitHub.
The investment for small environments is quite significant. There has to be a compelling case to enhance the areas where SUSE Rancher brings in value to make such a financial leap. There is also a free version to test the value propositions, which will help support the user's buying decisions. More clusters, more volume, more tasks and more complexity in the environment equals more value that Rancher can provide.
Positive impact, since it simplifies the deployment time by a huge margin. Without cloud foundry, deploying a code needs coordination with infrastructure teams, while with cloud foundry, its a simple one line command. This reduces the deployment time from at least few hours to few minutes. Faster deployments promote faster dev cycle iterations.
Code maintenance such as upgrading a Node or Java version is as simple as updating the build-pack. Without cloud foundry, using web logic, the specific version only supports a specific version of Java. So updating the version involves upgrading the version of web logic that needs to involve few teams. So without cloud foundry, it takes at least few days, with cloud foundry, its a matter of few mins.
Overall, happier Developers and thats harder to quantify.
