<p>With the new platform, Pearson will increase stability and performance, and to bring products to market more quickly. The company says its engineers will also get a productivity boost because they won’t spend time managing infrastructure. Jackson estimates 15 to 20 percent in productivity savings.</p>
<p>Beyond that, Pearson says the platform will encourage innovation because of the ease with which new applications can be developed, and because applications will be deployed far more quickly than in the past.

To solve the problem, Wikimedia Tool Labs migrated parts of its infrastructure to Kubernetes, in preparation for eventually moving its entire system. Yuvi said Kubernetes greatly simplifies maintenance. The goal is to allow developers creating bots and other tools to use whatever development methods they want, but make it easier for the Wikimedia Tool Labs to maintain the required infrastructure for hosting and sharing them.

In the future, with a more complete migration to Kubernetes, Wikimedia Tool Labs expects to make it even easier to host and maintain the bots and tools that help run wikis across the world. The tool labs already host approximately 1,300 tools and bots from 800 volunteers, with many more being submitted every day. Twenty percent of the tool labs’ web tools that account for more than 60 percent of web traffic now run on Kubernetes. The tool labs has a 25-node cluster that keeps up with each new Kubernetes release. Many existing web tools are migrating to Kubernetes.

Our goal is to make sure that people all over the world can share knowledge as easily as possible. Kubernetes helps with that, by making it easier for wikis everywhere to have the tools they need to thrive, says Yuvi.

Network is achieved using L3 routing. Because third-party networking plugins (e.g. flannel, calico, etc) don’t natively work on Windows Server, existing technology that is built into the Windows and Linux operating systems is relied on. In this L3 networking approach, a /16 subnet is chosen for the cluster nodes, and a /24 subnet is assigned to each worker node. All pods on a given worker node will be connected to the /24 subnet. This allows pods on the same node to communicate with each other. In order to enable networking between pods running on different nodes, routing features that are built into Windows Server 2016 and Linux are used.

### Linux
The above networking approach is already supported on Linux using a bridge interface, which essentially creates a private network local to the node. Similar to the Windows side, routes to all other pod CIDRs must be created in order to send packets via the public NIC.

### Windows
Each Window Server node should have the following configuration:

1. Two NICs (virtual networking adapters) are required on each Windows Server node - The two Windows container networking modes of interest (transparent and L2 bridge) use an external Hyper-V virtual switch. This means that one of the NICs is entirely allocated to the bridge, creating the need for the second NIC.
2. Transparent container network created - This is a manual configuration step and is shown in **_Route Setup_** section below
3. RRAS (Routing) Windows feature enabled - Allows routing between NICs on the box, and also captures packets that have the destination IP of a POD running on the node. To enable, open Server Manager. Click on Roles”, “Add Roles. Click Next. Select Network Policy and Access Services. Click on Routing and Remote Access Service and the underlying checkboxes
4. Routes defined pointing to the other pod CIDRs via the public NIC - These routes are added to the built-in routing table as shown in **_Route Setup_** section below

When we create a Deployment on Kubernetes, that Deployment creates Pods with containers inside them (as opposed to creating containers directly). Each Pod is tied to the Node where it is scheduled, and remains there until termination (according to restart policy) or deletion. In case of a Node failure, identical Pods are scheduled on other available Nodes in the cluster.</p>
