Completely unreliable and doesn't fit with modern workflows
Pros
- Mesos let us orchestrate containers on our own hardware using our own DNS. We switched from Docker Cloud, which caused several major outages for us.
Cons
- 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.
Return on Investment
- Developers needed to spend hours waiting to verify that their supposedly automated CD deploys actually went through.
- Lots of late night and early morning calls that Mesos deploys are hanging again.
- 10-20 hours spent building a custom service just to integrate Mesos with a CD provider.

Mesos, a great way to optimize your servers' resources
Pros
- 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.
Cons
- The community is good but they are not focusing on web apps deployment. I would like to see the community around Marathon growing.
- I would like to have a better support for rkt as a Mesos executor
Return on Investment
- 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.
