Which one should I use?
That depends—do you need a small instance of something that can be moved easily (containers), or do you need a semi-permanent allocation of custom IT resources?
The small, lightweight nature of containers allows them to be moved easily across bare metal systems as well as public, private, hybrid, and multicloud environments. They’re also the ideal environment to deploy today’s cloud-native apps, which are collections of microservices designed to provide a consistent development and automated[1] management[2] experience across public[3], private[4], hybrid[5], and multicloud[6] environments. Cloud-native apps help speed up how new apps are built, how existing ones are optimized, how they’re all connected. The caveat is that containers have to be compatible with the underlying OS. Compared to VMs, containers are best used to:
