ClusterHQ Introduces Flocker 0.1 For Docker

Industry veterans aim to make Dockerized application storage production-ready

ClusterHQ, The Data People for Docker, on Wednesday announced Flocker 0.1, a solution for running databases, key-value stores and queues inside Docker containers. An open-source volume manager, Flocker is a container management tool designed to solve the unique set of operational challenges that come from running data-backed services inside containers. Flocker version 0.1 allows developers to define their application as a set of connected Docker containers, deploy and then easily migrate them between hosts, even when in different data centers.

"Managing containers with persistent state is a significant problem today," said Gabriel Monroy, founder and CTO of Deis. "Containerized databases are not suitable for production workloads without solutions for data migration, cloning and failover. We are excited to see the ClusterHQ team tackling these problems head-on."

The proliferation of Linux containers is exploding, with analyst firm MarketsandMarkets forecasting that the global Platform-as-a-Service (PaaS) market will grow from $1.28 billion in 2013 to $6.94 billion in 2018, a CAGR of over 32 percent. As the primary unit of deployments for PaaS, Linux containers will make up a larger and larger part of that market.

Efficient Storage for Containers
Flocker is the result of more than five years of research, development and operational experience combining resilient distributed storage with containers. Two years ago the company launched HybridCluster, an advanced container management platform based on FreeBSD Jails for the web hosting industry. The company has large scale customer deployments of HybridCluster, which have proven the resilience and scalability of the platform. This experience running containers in production on FreeBSD has enabled the company to move extremely quickly to solve the data problem for Docker and Linux.

Flocker benefits include:

  • 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 management team, technical experts in storage, networking and containers, has proven experience driving open source adoption and marketing to developers. The combined team holds seven patents related to operating container-based applications at scale.

"ClusterHQ will do for containers what vCenter did for VMs," said Luke Marsden, CEO of ClusterHQ. "Containers and PaaS currently only capture the easy, data-free parts of an application. Flocker captures the entire app, enabling distributed data management, dynamic resource scheduling and high availability. Addressing these critical needs will unlock pent up demand for containers, driving the market to even greater heights."

Flocker is available today on Github under an Apache 2.0 license.

"We're a cybersecurity firm that specializes in engineering security solutions both at the software and hardware level. Security cannot be an after-the-fact afterthought, which is what it's become," stated Richard Blech, Chief Executive Officer at Secure Channels, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.
In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lead...
In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
Video experiences should be unique and exciting! But that doesn’t mean you need to patch all the pieces yourself. Users demand rich and engaging experiences and new ways to connect with you. But creating robust video applications at scale can be complicated, time-consuming and expensive. In his session at @ThingsExpo, Zohar Babin, Vice President of Platform, Ecosystem and Community at Kaltura, discussed how VPaaS enables you to move fast, creating scalable video experiences that reach your aud...
All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud. In his session at @DevOpsSummit at19th Cloud Expo, Valentin (Val) Bercovici, CTO of Soli...
"Once customers get a year into their IoT deployments, they start to realize that they may have been shortsighted in the ways they built out their deployment and the key thing I see a lot of people looking at is - how can I take equipment data, pull it back in an IoT solution and show it in a dashboard," stated Dave McCarthy, Director of Products at Bsquare Corporation, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.
What happens when the different parts of a vehicle become smarter than the vehicle itself? As we move toward the era of smart everything, hundreds of entities in a vehicle that communicate with each other, the vehicle and external systems create a need for identity orchestration so that all entities work as a conglomerate. Much like an orchestra without a conductor, without the ability to secure, control, and connect the link between a vehicle’s head unit, devices, and systems and to manage the ...
An IoT product’s log files speak volumes about what’s happening with your products in the field, pinpointing current and potential issues, and enabling you to predict failures and save millions of dollars in inventory.

The Internet of Things (IoT) promises to simplify and streamline our lives by automating routine tasks that distract us from our goals. This promise is based on the ubiquitous deployment of smart, connected devices that link everything from industrial control systems to automobiles to refrigerators. Unfortunately, comparatively few of the devices currently deployed have been developed with an eye toward security, and as the DDoS attacks of late October 2016 have demonstrated, this oversight can ...

In his session at 19th Cloud Expo, Claude Remillard, Principal Program Manager in Developer Division at Microsoft, contrasted how his team used config as code and immutable patterns for continuous delivery of microservices and apps to the cloud. He showed how the immutable patterns helps developers do away with most of the complexity of config as code-enabling scenarios such as rollback, zero downtime upgrades with far greater simplicity. He also demoed building immutable pipelines in the cloud ...
