They are lightweight and make better use of the available resources.
Having these images makes it trivial to start up clusters of machines, all running the same application.As they contain just the files needed to run our app, and we control exactly which versions are installed, creating new running containers from an image is trivial and results are consistent: no more "this works on my machine.".Fully managed containerized apps add to the former "hardware" benefits the "software" benefits of ease of deployment, configuration management, replicability, etc.Ĭontainerized applications are a perfect solution for multiple problems: When we start using computing nodes in the cloud, these can range from full-blown virtual machines (that emulate hardware and include a full guest operating system) to containers, lightweight computing nodes that share the kernel of the host machine and just add a filesystem with the OS and the applications needed.

And especially: no need to shut down our servers and get them off the rack to upgrade RAM.
Although we'll always have some workloads running on premises, the benefits of a managed solution are obvious: less downtime due to power outages or dropped Internet connections, instant scalability - both vertical (adding more resources to a computing node) and horizontal (distributing a workload among multiple nodes) - no need to pay big air conditioning bills to maintain our servers cool, etc. Each day, more and more workloads are moved to the cloud.
