After an AMI is launched, the resulting running system is called anÂ instance. By default, you can run up to 20 instances .Instances remain running unless they fail or you stop or terminate them. When this happens, the data on the instance (the “instance store” or “ephemeral store”) is no longer available. Also, by default AWS delete all Amazon EBS volumes that were attached at the time the instance launched. Any volumes you attached after instance launch continue to exist until you explicitly delete them.
Its is very easy to mange your AWS EC2 Instance as the controlÂ panelÂ gives all the options to start, stop or reboot the server.
AsÂ shownÂ in the screenshot , you right click on the server (Instance) and select the desired option to start, stop or reboot the Instance.
