OpenShift alternatives

1

OpenShift

The OpenShift platform was released by Red Hat – the maker of the professional Linux distribution “Red Hat Enterprise Linux” (RHEL). The OpenShift alternative “Rancher” has now been taken over by the traditional Linux provider SUSE. “Canonical Kubernetes”, is another OpenShift alternative from an established Linux provider. Read on to find out more about these and other alternatives to OpenShift.

Canonical

The biggest advantages of Canonical Kubernetes are flexibility and low cost of deployment. “Charmed Kubernetes” is an exciting operator-based approach to build infrastructures. “Charms” is a collection to seamlessly integrate and manage Kubernetes, container and VM-based applications across hybrid cloud environments. Canonical Kubernetes uses Ubuntu as operating system.

Mirantis Kubernetes Engine

The Mirantis Kubernetes Engine occupies an interesting niche. For example, in addition to Linux, it also supports Windows to run on nodes. Interestingly, Linux and Windows nodes can be mixed seamlessly, and the same applies to nodes with Kubernetes or Docker Swarm. The product is aimed at larger businesses. Thus, it unfortunately lacks a vibrant community of developers and the free trial version requires registration.

VMware Tanzu

The advantages of VMware Tanzu are primarily its integrated tools. The “VMware Tanzu Application Catalog” contains a well-maintained catalog of open source components and applications while “Harbor” is a dedicated container registry to secured different build artifacts by means of role-based access controls. The container images stored in Harbor are checked for security holes and vulnerabilities and marked as secure. The focus when using VMware Tanzu is clearly on the deployment of vSphere infrastructure. Support for other cloud platforms is less sophisticated.

Giant Swarm

The platform manages and optimizes the entire lifecycle of containerized applications and is quickly deployable. Unlike OpenShift, a Giant Swarm installation can be set up within a day. Since an unmodified Kubernetes distribution is used, it is relatively easy to move parts of the infrastructure between cloud environments. This reduces the risk of vendor lock-in. On the negative side, it is noticeable that there is no uniform pricing model. Instead, the price is tailored according to the client’s needs.

Portainer

The main advantage of Portainer is the flexibility of the software. In addition to Kubernetes, Docker Swarm and Docker can be used to manage clusters and containers. Portainer is based on open-source software and is offered in a freely available community version as well as a paid version with enterprise support. The software can be installed in cloud environments, on edge devices, or within a client’s existing computing infrastructure. Since Portainer is relatively new, the documentation leaves much to be desired.
