<p>A multinational company that's the largest telecommunications equipment manufacturer in the world, Huawei has more than 180,000 employees. In order to support its fast business development around the globe, <ahref="http://www.huawei.com/">Huawei</a> has eight data centers for its internal I.T. department, which have been running 800+ applications in 100K+ VMs to serve these 180,000 users. With the rapid increase of new applications, the cost and efficiency of management and deployment of VM-based apps all became critical challenges for business agility. "It's very much a distributed system so we found that managing all of the tasks in a more consistent way is always a challenge," says Peixin Hou, the company's Chief Software Architect and Community Director for Open Source. "We wanted to move into a more agile and decent practice."</p>

<p>"By the end of 2016, Huawei's internal I.T. department managed more than 4,000 nodes with tens of thousands containers using a Kubernetes-based Platform as a Service (PaaS) solution," says Hou. "The global deployment cycles decreased from a week to minutes, and the efficiency of application delivery has been improved 10 fold." For the bottom line, he says, "We also see significant operating expense spending cut, in some circumstances 20-30 percent, which we think is very helpful for our business." Given the results Huawei has had internally – and the demand it is seeing externally – the company has also built the technologies into <ahref="http://developer.huawei.com/ict/en/site-paas">FusionStage™</a>, the PaaS solution it offers its customers.</p>

<p>Huawei's Kubernetes journey began with one developer. Over two years ago, one of the engineers employed by the networking and telecommunications giant became interested in <ahref="http://kubernetes.io/">Kubernetes</a>, the technology for managing application containers across clusters of hosts, and started contributing to its open source community. As the technology developed and the community grew, he kept telling his managers about it.</p>

<p>And as fate would have it, at the same time, Huawei was looking for a better orchestration system for its internal enterprise I.T. department, which supports every business flow processing. "We have more than 180,000 employees worldwide, and a complicated internal procedure, so probably every week this department needs to develop some new applications," says Peixin Hou, Huawei's Chief Software Architect and Community Director for Open Source. "Very often our I.T. departments need to launch tens of thousands of containers, with tasks running across thousands of nodes across the world. It's very much a distributed system, so we found that managing all of the tasks in a more consistent way is always a challenge."</p>

<p>Pleased with those initial results, and seeing a demand for cloud native technologies from its customers, Huawei doubled down on Kubernetes. In the spring of 2016, the company became not only a user but also a vendor.</p>

<p>"We built the Kubernetes technologies into our solutions," says Hou, referring to Huawei's <ahref="http://developer.huawei.com/ict/en/site-paas">FusionStage™</a> PaaS offering. "Our customers, from very big telecommunications operators to banks, love the idea of cloud native. They like Kubernetes technology. But they need to spend a lot of time to decompose their applications to turn them into microservice architecture, and as a solution provider, we help them. We've started to work with some Chinese banks, and we see a lot of interest from our customers like <ahref="http://www.chinamobileltd.com/">China Mobile</a> and <ahref="https://www.telekom.com/en">Deutsche Telekom</a>."</p>

Luckily because Huawei has a lot of employees, we can demonstrate the scale of cloud we can build using this technology. We provide customer wisdom." While Huawei has its own private cloud, many of its customers run cross-cloud applications using Huawei's solutions. It's a big selling point that most of the public cloud providers now support Kubernetes. "This makes the cross-cloud transition much easier than with other solutions," says Hou.</p>

"In the next 10 years, maybe 80 percent of the workload can be distributed, can be run on the cloud native environments. There's still 20 percent that's not, but it's fine. If we can make 80 percent of our workload really be cloud native, to have agility, it's a much better world at the end of the day."

<p>In the nearer future, Hou is looking forward to new features that are being developed around Kubernetes, not least of all the ones that Huawei is contributing to. Huawei engineers have worked on the federation feature (which puts multiple Kubernetes clusters in a single framework to be managed seamlessly), scheduling, container networking and storage, and a just-announced technology called <ahref="http://containerops.org/">Container Ops</a>, which is a DevOps pipeline engine. "This will put every DevOps job into a container," he explains. "And then this container mechanism is running using Kubernetes, but is also used to test Kubernetes. With that mechanism, we can make the containerized DevOps jobs be created, shared and managed much more easily than before."</p>

<p>Still, Hou sees this technology as only halfway to its full potential. First and foremost, he'd like to expand the scale it can orchestrate, which is important for supersized companies like Huawei – as well as some of its customers.</p>
