Does Container tech makes backups and RAID obsolete



  • Hi,

    Do containers and management platform for containers, makes all the hard work of making the server resilient obsolete like RAID and backups, however we will assume that the DB are hosted outside of this scope like on Amazon services.

    If you have a server running 500 containers, would it be easier for automation to spin up another 500 containers on new hardware (while dealing with whatever issues are caused by 500 containers being down) or easier to have RAID and simply swap a disk and continue on?

    FFS, No!

    Not even running something on Amazon services make it resilient, that's something you always have to do yourself!

    Doesn't really affect that at all. We've had containers since the early 1980s and all this stuff, like RAID, came AFTER that, not before. You need your systems to stay up and running exactly the same with or without containers.

    And why would DBs be out of scope?

    If you are trying to ask if stateless systems versus stateful need RAID and backups, containers doesn't change that either. Any situation where a container could skip those things, it could be skipped without a container. Basically... containerization has no bearing on the situation.

    Actually for "easier", the container spinups can be automated, but the drive swap requires a human. The real effort is in acquiring another server to spin them up on. One approach is ignoring that an entire replacement server is needed.

    Having a full server die and take all of its workloads with it has all the same impact with containers as with anything else. Containers are really just "really heavy threads", nothing more.
