Linux Containers LXD vs. SUSE Rancher

Linux Containers LXD works very well when you, as a software developer using Linux, need to spin up a development environment to build and work on a specific piece of software. For example, you need to build some software that is tested and developed target Ubuntu 18.04. You're able to quickly create a container for Ubuntu 18.04 and log into it to run commands and build your software. This is easier to do than setting a virtual machine - e.g - via Virtual Box, but is a lot clunkier than doing it via Docker containers which give you a much more flexible configuration of the environment and are easier to start, stop, connect and share with other developers.

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.

• GIT repositories.
• Authentication servers.
• Application instances.

Incentivized

• Public and private cloud infrastructure providers based on K8s CAPI
• REST API that can be used to integrate company services with Rancher
• GUI that is easy to learn and use in daily operations
• Builtin GitOps automation solution based on Fleet project
• It is fully open source

• Ease of use.
• Copying containers from one machine to another.
• Creation of containers with config files similar to Docker.

Incentivized

• 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.

Overall it deserves an 8 out of 10. The platform is very easy to use as long as the UI is stable. We have had a few buggy versions in the past. However the CLI is excellent and the platform is simple to manage and maintain. It is easy to deploy and offer for company wide use which increases utilization and ROI.

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.

Linux Containers LXD feels like a more primitive version of docker, docker-compose and similar projects from the docker ecosystem. The Dockerfile and docker-compose.yml methods of specifying a container setup, as well as the network and file configurations afforded by Docker make working with containers much easier and more reproducible than with Linux Containers LXD.

We started using SUSE Rancher in the early days and spent a large amount of time getting to know and love it. This was before the days of some of the likes of Amazon Web Services who may now provide a cheaper but less feature-rich alternative to SUSE Rancher, however we have yet to explore this.

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.
