The document discusses the adoption of persistent and portable storage solutions for Docker containers and microservices, highlighting a survey indicating that 70% of IT professionals want to run stateful applications in containers. It emphasizes the challenges of data management, such as the ephemeral nature of container data and the need for dynamic storage provisioning and migration. The Hedvig distributed storage platform is presented as a solution, offering flexible volume configurations and the ability to scale storage up to petabytes.

Visit https://clusterhq.com/2015/06/17/container-survey/ to access study. 70%want to run a database or other stateful service in containers 65%plan to use containers in production in the next 12 months 66%say data management is critical to success and a gating factor
- 3. State of Docker and storage The nature of container architectures. . . • Data inside a container is ephemeral • Volumes not portable between hosts But what if I want to. . . • Run a stateful application? • Dynamically provision storage? • Move apps between hosts? • Retain data past the life of the container? 3
- 4. 4 Dynamic storage provisioning Instantly create persistent virtual volumes up to petabytes in size Automatic data migration Automate volume movement from source to target nodes Flexible volume configuration Set volume features to meet unique application needs +
- 5. Elastic Scale to petabytes of data 5 Simple Provision block, file, and object storage with enterprise features Flexible Connects to any compute, runs in any cloud
