In mid 2014 we looked at the challenges enterprises are facing in the context of digitization, where traditional enterprises experience that more and more competitors from the IT sector are pushing into the core of their markets. A big part of Fujitsu’s customers are such traditional businesses, so we considered how we could help them and came up with three basic principles:

• Decouple applications from infrastructure - Focus on where the value for the customer is: the application.
• Decompose applications - Build applications from smaller, loosely coupled parts. Enable reconfiguration of those parts depending on the needs of the business. Also encourage innovation by low-cost experiments.
• Automate everything - Fight the increasing complexity of the first two points by introducing a high degree of automation.

We found that Linux containers themselves cover the first point and touch the second. But at this time there was little support for creating distributed applications and running them managed automatically. We found Kubernetes as the missing piece. Not a free lunch

The general approach of Kubernetes in managing containerized workload is convincing, but as we looked at it with the eyes of customers, we realized that it’s not a free lunch. Many  customers are medium-sized companies whose core business is often bound to strict data protection regulations. The top three requirements we identified are:

• On-premise deployments (with the option for hybrid scenarios)
• Efficient operations as part of a (much) bigger IT infrastructure
• Enterprise-grade support, potentially on global scale

We created Cloud Load Control with these requirements in mind. It is basically a distribution of Kubernetes targeted for on-premise use, primarily focusing on operational aspects of container infrastructure. We are committed to work with the community, and contribute all relevant changes and extensions upstream to the Kubernetes project. On-premise deployments

• Proven setup process, lowers risk of problems while setting up the cluster
• Reduction of provisioning time to minutes
• Repeatable process, relevant especially for large, multi-tenant environments

Cloud Load Control delivers these benefits for a range of platforms, starting from selected OpenStack distributions in the first versions of Cloud Load Control, and successively adding more platforms depending on customer demand.  We are especially excited about the option to remove the virtualization layer and support Kubernetes bare-metal on Fujitsu servers in the long run. By removing a layer of complexity, the total cost to run the system would be decreased and the missing hypervisor would increase performance.

Right now we are in the process of contributing a generic provider to set up Kubernetes on OpenStack. As a next step in driving multi-platform support, Docker-based deployment of Kubernetes seems to be crucial. We plan to contribute to this feature to ensure it is going to be Beta in Kubernetes 1.3. Efficient operations

Reducing operation costs is the target of any organization providing IT infrastructure. This can be achieved by increasing the efficiency of operations and helping operators to get their job done. Considering large-scale container infrastructures, we found it is important to differentiate between two types of operations:

• Platform-oriented, relates to the overall infrastructure, often including various systems, one of which might be Kubernetes.
• Application-oriented, focusses rather on a single, or a small set of applications deployed on Kubernetes.

Kubernetes is already great for the application-oriented part. Cloud Load Control was created to help platform-oriented operators to efficiently manage Kubernetes as part of the overall infrastructure and make it easy to execute Kubernetes tasks relevant to them.

The first version of Cloud Load Control provides a user interface integrated in the OpenStack Horizon dashboard which enables the Platform ops to create and manage their Kubernetes clusters.

Clusters are treated as first-class citizens of OpenStack. Their creation is as simple as the creation of a virtual machine. Operators do not need to learn a new system or method of provisioning, and the self-service approach enables large organizations to rapidly provide the Kubernetes infrastructure to their tenants.

As a Japanese company, quality and customer focus have the highest priority in every product and service we ship. This is where the actual value of Cloud Cloud Control comes from: it provides a specific version of the open source software which has been intensively tested and hardened to ensure stable operations on a particular set of platforms.

Acknowledging that container technology and Kubernetes is new territory for a lot of enterprises, expert assistance is the key for setting up and running a production-grade container infrastructure. Cloud Load Control comes with a support service leveraging Fujitsu’s proven support structure. This enables support also for customers operating Kubernetes in different regions of the world, like Europe and Japan, as part of the same offering. Conclusion

2014 seems to be light years away, we believe the decision for Kubernetes was the right one. It is built from the ground-up to enable the creation of container-based, distributed applications, and best supports this use case.

With Cloud Load Control, we’re excited to enable enterprises to run Kubernetes in production environments and to help their operators to efficiently use it, so DevOps teams can build awesome applications on top of it.
