For my workload I've struggled to see the advantage containers would give me. Maybe someone here can convince me, rather than the current justification of 'docker all the things'.

We have servers, they handle a lot of traffic. It's the only thing running on the machines and takes over all the resources of the machine. It will need all the RAM, and all 16 vCPUs are at ~90%.

It's running on GCP. To rollout we have a jenkins job that builds a tag, creates a package (dpkg) and builds an image. There's another jenkins job that deploys the new image to all regions and starts the update process, autoscaling and all that.

Can containers help me here?
