Amazon provides services to maintain (docker i.e) container services working on EC2 instances.
To my knowledge on a simple server, if you have 5 containers running the identical OSs as base, for instance docker doesnt invade separate resources for the OS itself 5 times. Despite 5 separate containers, identical reources are kept in memory once.
So if I use AWS EC2 container service, do I still have the same advantage? In one way, it seems like AWS infrastructure should already have identical base OSs under some other users. In one way they may not give you this advantage: each docker pretends like that is the only container running on a separate machine.
Any ideas?
