PaaS Anywhere Deploying an OpenShift PaaS into your Cloud Provider of Choice

These liaisons work to adopt a hybrid skill set such that they can understand and represent the needs, struggles, and capabilities of the respective teams they represent. The teams enable each other to complete requisite work through automated self-service portals, rather than manually implemented change tickets. Since OpenShift is built on top of Kubernetes, it adds extra features and functionality that may prove useful when choosing between solutions. Enterprise-level support will certainly be valuable for most large organizations. However, the added cost of running OpenShift may prove the deciding factor for many. OpenShift is a cloud-based Kubernetes container platform that’s considered both containerization software and aplatform-as-a-service .

Origin is augmented by application lifecycle management functionality and DevOps tooling. Origin updates as often as open source developers contribute via Git. Here you get the new feature the quickest but at the cost of stability. Red Hat Openshift is an enterprise offering, an open-source platform for deploying and managing containers i.e., Kubernetes.

OpenShift deployment and Ansible are helping engineers deploy faster than ever. They both empower DevOps engineers not only to automate the deployment of Kubernetes clusters in on-premises, hybrid, and multi cloud environments, but also all the other services in their end-to-end environments. Using Ansible, Cloud Volumes ONTAP automation can simplify OpenShift deployment.

  • Red Hat solutions give you security, community, and decades of experience with flexibility to grow and expand as your ideas do.
  • Autonomous development and delivery teams can make use of the platform to deliver business functionality at a higher pace, with reduced coordination.
  • Operators can leverage placement and policy to orchestrate environments that meet their best practices.
  • Managing storage is a distinct problem from managing compute resources.
  • Openshift platform requires a fully functional DNS server in the environment.

Just as the application catalog is key to OpenShift’s identity as a PaaS, the ability to deploy multiple Kubernetes clusters is primary to KaaS. That doesn’t mean the catalog can’t be useful, but most large enterprises end up turning off most of these services and re-populating it with their approved, validated, and tested set of services. For artifact repositories, OpenShift comes with its own, fairly sophisticated system, which is an augmented implementation of Docker Registry. It gets installed automatically via the same Ansible playbook as the rest of OpenShift, and is designed to interact with a single instance / K8s cluster. This option is best when development is centralized to a single (OpenShift-based) Kubernetes cluster.

Chapter 1. The OpenShift Container Platform

To run your application in a CaaS, you need to provide the application image you have built, which contains your application and any operating system libraries and programs you require. Although an application image contains a copy of these operating system libraries and programs, it is only your application process that is run. These together made it possible to create application images that could be easily moved between different systems, to then be run in a container, with higher confidence that they would work out of the box. In 2013 a company called dotCloud, a PaaS provider, announced in a lightning talk at PyCon US a tool called Docker. This tool was an outgrowth of the proprietary technology that dotCloud used to help run applications in containers; it provided a wrapper for making it easier to launch applications in containers using LXC. Under these traditional definitions for cloud service computing models, OpenShift would be classified a PaaS.

RHOO is based on OpenShift, which is Red Hat’s private PaaS cloud, but this is more than just a PaaS. Red Hat is providing an enterprise-ready container platform based on integrated Docker containers, which run on Red Hat Enterprise Linux and are managed by Kubernetes. Red Hat OpenShift is a multifaceted, open source container application development platform from Red Hat Inc. for the development, deployment and management of applications. Whether you’re building new applications or modernizing existing ones, OpenShift supports the most demanding workloads including AI/ML, edge, and more. Automate deployment and life-cycle management with our vast ecosystem of technology partners. Benefits of using a PaaS environment include offloading the responsibilities of maintaining servers, keeping infrastructure software updated, and having to set up a custom platform upon which to build your app.

It’s the platform software to deploy and manage OpenShift on your own infrastructure of choice. It integrates with Red Hat Enterprise Linux 6 and is tested via Red Hat’s QA process in order to offer a stable, supportable product with may be important for enterprises. Ultimately, the choice between PaaS and KaaS is going to depend on where you want to draw the line between devs and ops in your organization.

There are some great blogposts on the JWorks blog explaining more about them. A KaaS instance is many K8s instances running across many locations, but centrally controlled. An advantages of paas instance is a single instance of K8s running in a single location. KaaS and OpenShift achieve multi-tenancy in two different ways, and much of that difference has to do with the inherent logic and resulting architecture behind the two solutions. Readers who want to understand and learn OpenShift should have a basic knowledge of Docker and Kubernetes. Readers also need to have some understanding of system administration, infrastructure, and network protocol communication.

Mirantis KaaS doesn’t specify a CI/CD engine, and is designed to integrate with whatever the customer is already using. The Mirantis KaaS beta does not implement its own registry, but assumes that a user already has a registry in mind. If not, KaaS offers the option to co-deploy a Harbor registry with the Kubernetes cluster. Note that in KaaS, this registry is not typically tied to a single cluster, so you can use a single instance of Harbor to store artifacts from across multiple, geo-distributed K8s clusters.

Kubernetes offers more flexibility as an open-source framework and can be installed on almost any platform — like Microsoft Azure and AWS — as well as any Linux distribution, including Ubuntu and Debian. OpenShift, on the other hand, requires Red Hat’s proprietary Red Hat Enterprise Linux Atomic Host , Fedora, or CentOS. This narrows options for many businesses, especially if they’re not already using these platforms. If you wish to work through the example in the book yourself, you can use the playground environments on the OpenShift Interactive Learning Portal. The playgrounds don’t follow a set tutorial, and you are free to try anything you want.
