> As someone hoping to build a world-wide footprint Does adding an extra 100ms to the response time cost you that much business wise? As for colos, it depends on scale. If you have 30k servers world wide, it pays to have someone manage the contracts for you. If not it pays to go for the painful arseholes like vodaphone, or whoever bought Cable & wireless's stuff. as for security, it gets very difficult. You need to make sure that each machine is actually running _what_ you told it, and know if someone has inserted a hypervisor shim between you and your bare metal. none of that is off the shelf. Which is why people pay the big boys, so that they can prove chain of custody and have very big locks on the cages. K8s gives you scheduling and a datastore. For a large globally distributed system its going to scale like treacle.
