Likelihood to Recommend 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.
Read full review You are going to be able to find the most resources and examples using Docker whenever you are working with a container orchestration software like Kubernetes. There will always some entropy when you run in a container, a containerized application will never be as purely performant as an app running directly on the OS. However, in most scenarios this loss will be negligible to the time saved in deployment, monitoring, etc.
Read full review 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. Read full review Packaging of application to limit the space occupied Ease of running the application Provide multiple ways to handle the application issues and integration of different components like pipeline, ansible, terraform etc Read full review 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.

Read full review Reliability and Availability Haven't seen any outages, fatal/unrecoverable errors in my usage so far. Enough said.
Read full review Performance Docker Desktop. The CPU high usage is a known issue. Needs fixing. Otherwise, it is great overall. Would not use anything else still.
Read full review Support Rating No real support channel, the Mesos
GitHub issues list was the only one we found and it wasn't particularly helpful.
Read full review Alternatives Considered 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.
Read full review The reason why we are still using Docker right now is due to that is the best among its peers and suits our needs the best. However, the trend we foresee for the future might indicate Amazon lambda could potentially fit our needs to code enviornmentless in the near future.
Read full review Scalability It is the only tool in our toolset that has not [had] any issues so far. That is really a mark of reliability, and it's a testimony to how well the product is made, and a tool that does its job well is a tool well worth having. It is the base tool that I would say any organisation must have if they do scalable deployment.
Read full review 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.
