ClusterHQ and VMware Collaborate to Enable Integration Between Containers and VMware vSphere-Based Storage

New VMware vSphere Storage Driver for Flocker Delivers New Options for DevOps Teams to Use Containers With VMware Virtual SAN and VMware vSphere Virtual Volumes

SAN FRANCISCO – August 31, 2015 – ClusterHQ, The Container Data People, today announced an integration between ClusterHQ’s Flocker container data management software and VMware vSphere®. VMware collaborated with ClusterHQ to develop a pluggable storage driver for vSphere, providing portable and persistent shared storage for organizations using Docker containers in conjunction with VMware. Users will now have direct access to VMware vSphere-based storage – including VMware Virtual SAN™ and VMware vSphere Virtual Volumes™ – at the container level, allowing developer and operations (DevOps) teams to more easily run stateful container-based applications on VMware vSphere.

Despite the ability of containers to run directly on bare metal servers, a recent survey by of developer, operations and security professionals reveals that the vast majority of containers (73%) are still run inside virtual machines. Additionally, VMware is the most popular virtualization option by far, used by almost double the number of survey respondents as the closest competitor. The survey also revealed that security is the number one barrier to container adoption, followed closely by data management.

“Today, containers do a great job easing application portability, but there are many additional operational requirements that can be improved by combining containers with VMware’s software-defined data center infrastructure solutions,” said Skip Bacon, vice president, storage and availability, VMware. “By collaborating with ClusterHQ to make a VMware vSphere driver available for Flocker, we’re making it even easier for organizations deploying containerized applications to take advantage of the persistent storage options offered by VMware vSphere, including VMware Virtual SAN and vSphere Virtual Volumes.”

ClusterHQ’s Flocker enables stateful Docker containers to be easily migrated between virtual servers, which is important when developing applications that include stateful services like databases, queues and key-value stores. Flocker makes it simple and practical for entire applications, including their data, to be containerized and achieve true portability between development, staging and production. With the combination of Docker, VMware and Flocker, developers can adopt container technologies that speed their development and deployment processes while the operations team can continue using VMware infrastructure. This combined approach benefits both developers and operations teams, as both are able to use their platform of choice.

“Enterprise adoption of containers is accelerating, which means that it is more important than ever to enable stateful services to run in containers, without which, the benefits of containerization would be greatly diminished,” said Mark Davis, CEO, ClusterHQ. “By teaming with VMware, we open the door wider for enterprises to easily and seamlessly join the container movement, without having to replace existing infrastructure.”

About ClusterHQ

ClusterHQ makes data as portable, flexible and agile as the containers powering modern computing. The company’s suite of products– FlockerHub, Fli and Flocker–give developers and operations teams the control needed to manage the data powering microservices. At the center of the ClusterHQ platform is FlockerHub, which is like GitHub® for data. With it, teams can store and share any Docker data volume with access-controlled users or machines. Fli, a Git-like command line interface, snapshots, branches, pushes and pulls data volumes to FlockerHub. Used together, DevOps teams can seamlessly move data between laptops, test environments, data centers and clouds all with version and access controls. In addition to FlockerHub and Fli, customers worldwide use Flocker, the leading open source volume orchestrator designed make stateful containers portable in production. Flocker works with over 15 cloud and enterprise storage systems, including four of the five global leaders: EMC, HPE, Dell and NetApp. ClusterHQ provides unparalleled data management across entire containerized application lifecycles. We are the Container Data People™.
