Although containers aren’t new (been built into Linux for 10+ years and been available in FreeBSD, AIX and Solaris), containers seem to be all the rage, and for good reason. The agility containers can bring to an IT team alone make them appealing, but add in the security benefits that the self-contained nature of containers brings, they seem like a no brainer. But even with numerous benefits, there is also a lot of confusion about what they really are and what is the best-fit scenario. So, we thought we’d break it down…

Containers can run all sorts of applications, but because they are so different from VMs, a lot of the older software that many enterprises are still running won’t translate to this model. However, VMs can be used to move older applications into a cloud service. So even though containers have their benefits, VMs still do too. It really boils down to… it depends…
