Offers easy management and container connection with HTTPS, but the support needs to improve
I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

There are multiple areas where SUSE Rancher can improve. The most pressing issue that I found in SUSE Rancher is that it is a bit slow. Compared with Komodor, it is very slow. Maintenance is also very high, and we require regular maintenance. Non-experts in Kubernetes cannot handle this application. It is a bit less stable compared with other tools in the market. In most regions, there is scope for improvement. There is a lot of scope for improvement, and there are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability. It is a very good tool, so that is why I gave it a nine. However, it is not a great tool to get a ten. It is a bit costly compared with other tools in the market.
