ClusterHQ has launched Flocker 0.1, the container industry's first solution for reliably running databases, key-value stores and queues inside Docker containers. An open-source volume and container manager, Flocker is the only software that solves the significant operational challenges that come from running data-backed services inside containers. Flocker allows developers to define their application as a set of connected Docker containers, deploy and then easily migrate them along with their data between hosts, even when in different data centers.
The proliferation of Linux containers is exploding, with leading industry analyst firm MarketsandMarkets forecasting that the global PaaS market will grow over 32 percent per year from $1.28 billion in 2013 to nearly $7 billion in 2018. As a preferred unit of deployments for PaaS, Linux containers are expected to make up a large part of that market. Linux containers are also expected to be widely adopted in Global 2000 private clouds.
While the Linux container market is growing fast, its growth is held back by a lack of support for production- ready data services, the heart of most applications.
Efficient Storage for Containers
Flocker is the result of more than five years of research, development and operational experience combining resilient, distributed, commodity storage with containers. Two years ago, the company launched HybridCluster, an advanced container management platform based on FreeBSD Jails. Production customer deployments of HybridCluster have proven the resilience and scalability of ClusterHQ's advanced technology. This experience has enabled the company to move extremely quickly to solve the data problem for Docker and Linux.
Flocker adds the following benefits to the Docker platform:
- Ability to define an entire application, including its databases, as a set of connected containers
- Easy migration of databases, queues and key values stores along with rest of the application
- Support for deployment to and between any public, private or bare metal clouds
The ClusterHQ team are technical experts in storage, networking and containers who have successfully driven open source adoption in developer-led communities. The team holds seven patents related to operating container-based applications at scale.
Just as the virtual machine (VM) market required an enormous amount of capabilities to be developed around the hypervisor in order to fully mature, the Docker market needs the kind...
