Kubernetes Review

Easy container management, affordable, and majority of installations straightforward

What is our primary use case?

We use the solution to modernize our IT landscape. We use infrastructure and platform surfaces for our data center. More recently we have added a container as a surface, which is this solution.

What is most valuable?

The easy deployment of containers is one of the main features I have found useful. In large scale developments, it is less hassle working with containers than virtual machines. It is easier to manage these containers instead of virtual machines, although there is a steep learning curve to graps the benefits of it.

What needs improvement?

This solution is not very easy to use. We are looking also for some tools surrounding this solution to manage the environment and to secure it better. These two are areas that have caused some issues. We want to integrate it with what you call continuous integration and delivery. 

It must be scalable, cost-effective, more agile when it comes to developing and managing the environment for DevOps. All these things go together, it must be cured to allow better manageability. That is what we all are doing in most large companies.

In a future release, the solution could become more like a core engine, in which tools like OpenShift are centered. You could see how all kinds of tools could help to better improve the management, security, or scalability of the product. Additionally, we will need more than the core in our organization, there needs to be more additional management tools moving forward.

For how long have I used the solution?

I have been using the solution for approximately one year.

What do I think about the scalability of the solution?

When it comes to my own environment, I have had no issues with scalability but it is not easy. This is just the development environment. Regarding my company, within my department, we are running a sandbox environment just for testing and that is going well. I am not sure how things will go if you go fully into production with this solution.

We will look for additional products to deal with the difficulties with scalability. There are several vendors that offer these products. Although this solution was made for scalability, it does not come out of the box this way.

We currently have approximately 30 users using the solution in my organization.

How was the initial setup?

I am not aware exactly how the on-premises installation went for the IT team at my organization. For my local environment where I am testing this solution myself, the installation has been very easy. This is mostly because it is a local environment. We also have a cloud environment, where we have a hybrid data center and this cloud environment installation was fairly easy too.

What about the implementation team?

The deployment was done by an internal team in my organization. 

Maintenance is required for all software versions. We need to manage different areas of the solution such as the cloud-native landscape tooling, registry, DevOps environment, and security toolings. There are three areas that need upgrades, versioning, scalability, and the toolset surrounding the solution. You can not run it on its own, you need additional tools. All of this maintenance is taken care of by our administration IT department.

What's my experience with pricing, setup cost, and licensing?

The solution is affordable.

What other advice do I have?

We plan on using the solution in the future. We are a large data center and we just need to have several options available. We need to have a traditional deployment of Infrastructure as a service, with virtual machines. We need also a platform as a service for very rapid and smaller applications and container management, container as a service which is this solution for all others. We expect that the virtual machines in the next 10 years will decrease and container-based services will increase.

I recommend the solution to others. It is a very good product and the strength can be that other vendors can create their security and management toolings around it allowing it to become a type of core engine. If those other vendors were not there, I think I would be more critical. Within my department, we were a bit late adopting the solution than other parts of the organization. We are still growing and experimenting, we have some clusters already in production. A lot of the product tools are open source which in some cases means the support is also not readily available. You have to adapt to it, but also be cautious when it comes to the support and the steep learning curve issues that you can expect.

I rate Kubernetes an eight out of ten.
