Apache Mesos vs. GoDaddy Container-as-a-Service (ElasticHosts, Springs.io), discontinued

There's really no reason to ever use Mesos. We switched over to Kubernetes and it's been a breath of fresh air - better CD support, easy CLI for browsing logs, no mysterious dangling redeploys. If you're looking for a tool to manage a fleet of Docker containers on VMs, Kubernetes beats Mesos by a wide margin.

Incentivized

Unlike other providers, Springs doesn’t use a pre-built container solution, instead opting for their own software built from the ground up.

• Mesos may have many frameworks. If you have Mesos installed on your servers, you may use it for many kinds of tasks. Today we're running only web applications but the idea is to install a different framework for big data soon.
• There is a good community growing around it.

Incentivized

• Container hosting, cloud virtualization
• Elastic capacity scaling and pay-per-use billing
• Linux kernel containerization technologies for container isolation and control

Incentivized

• Unreliable deployments that would fail for no good reason. Sometimes our Docker container would be "restarting" forever because Mesos thought it didn't have enough resources to start the container.
• Impossibly slow UI. Built in React under the hood with a lot of bloatware backed in, so loading the Mesos UI on a slow internet connection was painful.
• No real logging solution - it would stream "console.log()" output to the UI, but searching for logs wasn't really possible without downloading a huge file.
• No built-in support for redeploying containers from a CI. We had to create a service whose whole job was to expose an HTTP endpoint that restarted a container, and then made Circle CI ping the endpoint whenever we wanted to redeploy.

Incentivized

• Provide more options at lower costs
• It would be nice to see that expanded out to more distributions. What would be potentially even better though is templates. Some hosts can deploy ready-to-run WordPress/Drupal sites, LAMP instances, ownCloud instances, etc. at the drop of a hat. If Springs could replicate this with their container hosting they’d immediately appeal to a much, much wider audience;

No real support channel, the Mesos GitHub issues list was the only one we found and it wasn't particularly helpful.

Incentivized

Kubernetes is really great and their community is growing really fast (Google influence). We evaluated it in the beginning and it would fit for our web applications workload. We decided to proceed with Mesos because it has more potential. You may use a different framework for different kinds of tasks on Mesos. There is a Kubernetes framework for Mesos, by the way.

Springs is drastically cheaper than running 4 OVH servers, and a little cheaper than running nano instances on AWS.

• It's optimizing our resources.
• It's improving our process. This argument is not just for Mesos, but we needed a tool like this to start changing and it works like a charm.
• It's open source.

Incentivized

• In the beginning I wasn’t sure what I should set it to for my web server, so I left it. After a while the Average usage area begins showing how much resource the container is demanding and from that more adequate limits can be set.
