It was not that long ago when organizations had in-house servers humming along running applications and storing data. Today, the opportunity afforded by containers means that applications can now live on a cloud platform (either public or private), or one of several available cloud platforms.
But while applications and microservices housed in stateless containers are easy to move from place to place (indeed, that’s a big part of the appeal of containers), the data the applications are accessing are stateful and very, very difficult to relocate while still maintaining consistency, latency, and throughput. This is one of the challenges faced by the Red Hat Storage team, and addressed by Sage Weil in his recent presentation at Red Hat Summit: maintaining data availability with acceptable latency when working with applications in multi-cloud and hybrid cloud environments.

In Part 1 of Now + Next’s closer look at the future of container storage, we examined the beginnings of the storage solution with a look at how hardware trends will affect the way storage and containers will evolve together.
In this installment, Ceph Project Lead Sage Weil continues our conversation, moving “up” the stack to software platforms. Specifically, Sage discusses where container technology is now and where it is going.

The rise of container technology has created a new challenge for the storage industry. Within containers, applications, and computation resources are now incredibly mobile, while storage still has to remain persistent and accessible. Here’s how Red Hat is working to address the storage needs of container workloads.
In modern microservice-based architectures, each container is a transient object. It might live on one server for a while and then get moved over to another if directed by an orchestrator tool. While a container keeps its bundle of application software and dependencies during its lifecycle, it usually does not keep application data within the container. Nor should it. After all, in this model a container is designed to run only what is needed and when it is needed. When done, the container is allowed (in fact encouraged) to disappear. If an application’s data were held inside that same application container, too, then pfft!
That’s a challenge.
