Kubernetes Grows Up – The View from KubeCon EU 2019

Our little Kubernetes is growing up.

By “growing up” I mean it is almost in a state that a mainstream company can consider it fit for production. While there are several factors that act as a drag against mainstream reception, a lack of completeness has been a major force against Kubernetes broader acceptance. Completeness, in this context, means that all the parts of an enterprise platform are available off the shelf and won’t require a major engineering effort on the part of conventional IT departments.

The good news from KubeCon+CloudNativeCon EU 2019 in Barcelona, Spain (May 20 – 23 2019) is that the Kubernetes and related communities are zeroing in on that ever so important target. There are a number of markers pointing toward mainstream acceptance. Projects are filling out the infrastructure – gaining completeness – and the community is growing.

Project Updates

While Kubernetes may be at the core, there are many supporting projects that are striving to add capabilities to the ecosystem that will result in a more complete platform for microservices. Some of the projects featured in the project updates show the drive for completeness. For example, OpenEBS and Rook are two projects striving to make container storage more enterprise friendly. Updates to both projects were announced at the conference. Storage, like networking, is an area that must be tackled before mainstream IT can seriously consider container microservices platforms based on Kubernetes.

Managing microservices performance and failure is a big part of the ability to deploy containers at scale. For this reason, the announcement that two projects that provide application tracing capabilities, OpenTracing and OpenCensus, were merging into OpenTelemetry is especially important. Ultimately, developers need a unified approach to gathering data for managing container-based applications at scale. Removing duplication of effort and competing agendas will speed up the realization of that vision.

Also announced at KubeCon+CloudNativeCon EU 2019 were updates to Helm and Harbor, two projects that tackle thorny issues of packaging and distributing containers to Kubernetes. These are necessary parts of the process of deploying Kubernetes applications. Securely managing container lifecycles through packaging and repositories is a key component of DevOps support for new container architectures. Forward momentum in these projects is forward movement toward the mainstream.

There were other project updates, including updates to Kubernetes itself and Crio-io. Clearly, the community is filling in the blank spots in container architectures, making Kubernetes a more viable application platform for everyone.

The Community is Growing

Another gauge pointing toward mainstream acceptance is the growth in the community. The bigger the community, the more hands to do the work and the better the chances of achieving feature critical mass. This year in Barcelona, KubeCon+CloudNativeCon EU saw 7700 attendees, nearly twice last year in Copenhagen. In the core Kubernetes project, there are 164K commits and 1.2M comments in Github. This speaks to broad involvement in making Kubernetes better. Completeness requires lots of work and that is more achievable when there are more people involved.

Unfortunately, as Cheryl Hung, Director of Ecosystems at CNCF says, only 3% of contributors are women. The alarming lack of diversity in the IT industry shows up even in Kubernetes despite the high-profile women involved in the conference such as Janet Kuo of Google. Diversity brings more and different ideas to a project and it would be great to see the participation of women grow.

Service Mesh Was the Talk of the Town

The number of conversations I had about service mesh was astounding. It’s true that I had released a pair of papers on it, one just before KubeCon+CloudNativeCon EU 2019. That may have explained why people want to talk to me about it but not the general buzz. There was service mesh talk in the halls, at lunch, in sessions, and from the mainstage. It’s pretty much what everyone wanted to know about. That’s not surprising since a service mesh is going to be a vital part of large scale-out microservices applications. What was surprising was that even attendees who were new to Kubernetes were keen to know more. This was a very good omen.

It certainly helped that there was a big service mesh related announcement from the mainstage on Tuesday. Microsoft, in conjunction with a host of companies, announced the Service Mesh Interface. It’s a common API for different vendor and project service mesh components. Think of it as a lingua franca of service mesh. There were shout-outs to Linkerd and Solo.io. The latter especially had much to do with creating SMI. The fast maturation of the service mesh segment of the Kubernetes market is another stepping stone toward the completeness necessary for mainstream adoption.

Already Way Too Many Distros

There were a lot of Kubernetes distributions a KubeCon+CloudNativeCon EU 2019. A lot. Really.  A lot. While this is a testimony the growth in Kubernetes as a platform, it’s confusing to IT professionals making choices. Some are managed cloud services; others are distributions for on-premises or when you want to install your own on a cloud instance. Here’s some of the Kubernetes distros I saw on the expo floor.  I’m sure I missed a few:

Microsoft Azure Google Digital Ocean Alibaba
Canonical (Ubuntu) Oracle IBM Red Hat
VMWare SUSE Rancher Pivotal
Mirantis Platform9

 

From what I hear this is a sample, not a comprehensive, list. The dark side of this enormous choice is confusion. Choosing is hard when you get beyond a handful of options. Still, only five years into the evolution of Kubernetes, it’s a good sign to see this much commercial support for it.

The Kubernetes and Cloud Native architecture is like a teenager. It’s growing rapidly but not quite done. As the industry fills in the blanks and as communities better networking, storage, and deployment capabilities, it will go mainstream and become applicable to companies of all sizes and types. Soon. Not yet but very soon.

Docker Enterprise 3.0 is the Docker We’ve Been Waiting For

For the past few years, one of the big questions in the software industry has been what direction Docker would take. Much of their unique intellectual property, such as Docker images, had been open sourced and many of their products have underperformed. Docker Swarm is an excellent example of a product that was too little too late. While loved by Docker customers I spoke with, Docker Swarm simply couldn’t surf the swell that is the

Google Goes Corporate at Google Next

There’s no doubt that Google exists to make money. They make money by getting companies to buy their services. When it comes to selling ads on search engines, Google is number one. When it comes to their cloud business, Google is… well, number three.

I’m guessing that irks them a bit especially since they sit behind a company whose main business is selling whatever stuff people want to sell and a company that made its name in the first wave of PCs. Basically, a department store and a dinosaur are beating them at what should be their game.

Coming Attractions: Groundbreaking Service Mesh Research

In early January, I started researching the service mesh market. To oversimplify, a service mesh is a way of providing for the kind of network services necessary for enterprise applications deployed using a microservices architecture. Since most microservices architectures are being deployed within containers and, most often, managed and orchestrated using Kubernetes, service mesh technology will have a major impact on the adoption of these markets.

As I began writing the original paper, I quickly realized that an explanation of service mesh technology was necessary to understand the dynamic of the service mesh market. Creating a primer on service mesh and a market guide turned out to be too much for one paper. It was unbearably long. Subsequently, the paper was split into two papers, a Technical Guide and a Market Guide.

The Technical Guide is a quick primer on service mesh technology and how it is used to enhance microservices architectures, especially within the context of containers and Kubernetes. The Market Guide outlines the structure of the market for service mesh products and open source projects, discusses many of the major players, and talks to the current Istio versus Linkerd controversy. The latter is actually a non-issue that has taken on more importance than it should given the nascence of the market.

The Technical Guide will be released next week, just prior to Cloud Foundry Summit. Even though service mesh companies seem to be focused on Kubernetes, anytime there is a microservices architecture, there will be a service mesh. This is true for microservices implemented using Cloud Foundry containers.

The Market Guide will be published roughly a month later, before Red Hat Summit and KubeCon+CloudNative Summit Europe, which I will be attending. Most of the vendors discussed in the Market Guide will be in attendance at one or the other conference. Read the report before going so that you know who to talk to if you are attending these conferences.

A service mesh is a necessary part of emerging microservices architectures. These papers will hopefully get you started on your journey to deploying one.

Note: Vendors interested in leveraging this research for commercial usage are invited to contact Lisa Lincoln (lisa@amalgaminghts.com).

The View from KubeCon+CloudNativeCon – Containers and Kubernetes Become Enterprise Ready

In case there was any doubt about the direction containers and Kubernetes are going, KubeCon+CloudNativeCon 2018 in Seattle should have dispelled them. The path is clear – technology is maturing and keeps adding more features that make it conducive to mission-critical, enterprise applications. From the very first day, the talk was about service meshes and network functions, logging and traceability, and storage and serverless compute. These are couplets that define the next generation of management, visibility, and core capabilities of a modern distributed application. On top of that is emerging security projects such as SPIFFE & SPIRE, TUF, Falco, and Notary. Management, visibility, growth in core functionality, and security. All of these are critical to making container platforms enterprise ready.

“The future of containers and Kubernetes as the base of the new stack was on display at KubeCon+CloudNativeCon and it’s a bright one.

Tom Petrocelli, Research Fellow, Amalgam Insights”

If the scope of KubeCon+CloudNativeCon and the Cloud Native Computing Foundation (CNCF) is any indication, the ecosystem is also growing. This year there were 8000 people at the conference – a sellout. The CNCF has grown to 300+ vendor members there are 46,000 contributors to its projects. That’s a lot of growth compared to just a few years ago. This many people don’t flock to sinking projects.

Containers Continue on Track for 2019: 3 Key Trends For the Maturing Container Ecosystem

Tom Petrocelli, Amalgam Insights Research Fellow

The past few years have been exciting ones for containers. All types of tools are available and a defined deployment pipeline has begun to emerge. Kubernetes and Docker have come to dominate the core technology. That, in turn, has brought the type of stability that allows for wide-scale deployments. The container ecosystem has exploded with lots of new software components that help maintain, manage, and operate container networks. Capabilities such as logging, load balancing, networking, and security that were previously the domain of system-wide software and appliances are now being brought into the individual application as components in the container cluster.

Open Source has played a big part in this process. The Cloud Native Computing Foundation, or CNCF, has projects for all things container. More are added every day. That is in addition to the many other open source projects that support container architectures. The ecosystem just keeps growing.

Where do we go from here, at least through 2019?

Hanging out with the Cool Oracle Kids

When I wrote my last article on open source at Oracle, I got some feedback. Much of it was along the lines are “Have you hit your head on something hard recently?” or “You must be living in an alternate dimension.” While the obvious answer to both is “perhaps…” it has become increasingly obvious that…

Oracle Delivers a FOSS Surprise

An unfortunate side effect of being an industry analyst is that it is easy to become jaded. There is a tendency to fall back into stereotypes about technology and companies. Add to this nearly 35 years in computer technology and it would surprise no one to hear an analyst say, “Been there, done that, got…

Google Grants $9 Million in Google Cloud Platform Credits to Kubernetes Project

Tom Petrocelli, Amalgam Insights Research Fellow
Kubernetes has, in the span of a few short years, become the de facto orchestration software for containers. As few as two years ago there were more than a half-dozen orchestration tools vying for the top spot and now there is only Kubernetes. Even the Linux Foundation’s other orchestrator project, CloudFoundry Diego, is starting to give way to Kubernetes. Part of the success of Kubernetes can be attributed to the support of Google. Kubernetes emerged out of Google and they have continued to bolster the project even as it fell under the auspices of the Linux Foundation’s CNCF.

On August 29, 2018, Google announced that it is giving $9M in Google Cloud Platform (GCP) credit to the CNCF Kubernetes project. This is being hailed by both Google and the CNCF as an announcement of major support. $9M is a lot of money, even if it is credits. However, let’s unpack this announcement a bit more and see what it really means.
