>Apache Mesos is a system predominatly used by large companies, to more efficiently utilize servers in their data centers.

I love Apache Mesos as much as the next person, but this isn't true. It's predominantly used by Mesos devs. It's one of the up and coming hot technologies, but it hardly has enough users to say it's predominantly used by anyone more than enthusiasts and devs.

It's powering huge infrastructures as we speak; Twitter, Airbnb, and many others: http://mesos.apache.org/documentation/latest/powered-by-meso...

Last time I checked very few of them relied critically on Mesos (Twitter, some parts of Netflix, and Airbnb did IIRC). Most are just test deployments or non-critical applications. (e.g. I know Ebay and Paypal are also OpenStack users because they try all the new things).

Other than those, none of those are really huge companies. I have nothing against Mesos, but I hate overhyping something when it's still clearly in an early adopter phase. The side effect of overhyping is that the tooling isn't mature/simple enough for less ambitious people so they get a bad association with the project because they tried it too early after someone implied that it was mainstream already.
