Kubernetes vs. VMware vSOM (discontinued)

K8s should be avoided - If your application works well without being converted into microservices-based architecture & fits correctly in a VM, needs less scaling, have a fixed traffic pattern then it is better to keep away from Kubernetes. Otherwise, the operational challenges & technical expertise will add a lot to the OPEX. Also, if you're the one who thinks that containers consume fewer resources as compared to VMs then this is not true. As soon as you convert your application to a microservice-based architecture, a lot of components will add up, shooting your resource consumption even higher than VMs so, please beware. Kubernetes is a good choice - When the application needs quick scaling, is already in microservice-based architecture, has no fixed traffic pattern, most of the employees already have desired skills.

Vsphere Operation Management is suitable for automating the process of bringing up an alternate data center in case of a disaster. It also is a great way for testing your readiness of disaster. You have the ability to bring up a server in a "bubble" for testing. This way you can show your admins how the failover process will work.

• Complex cluster management can be done with simple commands with strong authentication and authorization schemes
• Exhaustive documentation and open community smoothens the learning process
• As a user a few concepts like pod, deployment and service are sufficient to go a long way

• The best thing about VSOM is that it's built into VCenter so you only have one point of administration
• VSOM does a great job of making applications intuitive
• Re-IPing virtual machines are a must and VSOM does a great job of making this a simple process

• Local development, Kubernetes does tend to be a bit complicated and unnecessary in environments where all development is done locally.
• The need for add-ons, Helm is almost required when running Kubernetes. This brings a whole new tool to manage and learn before a developer can really start to use Kubernetes effectively.
• Finicy configmap schemes. Kubernetes configmaps often have environment breaking hangups. The fail safes surrounding configmaps are sadly lacking.

Incentivized

• The installation of VSOM is very tedious
• It uses an MS SQL database
• It should be able to adjust for hardware modifications in VCenter

The Kubernetes is going to be highly likely renewed as the technologies that will be placed on top of it are long term as of planning. There shouldn't be any last minute changes in the adoption and I do not anticipate sudden change of the core underlying technology. It is just that the slow process of technology adoption that makes it hard to switch to something else.

It is an eminently usable platform. However, its popularity is overshadowed by its complexity. To properly leverage the capabilities and possibilities of Kubernetes as a platform, you need to have excellent understanding of your use case, even better understanding of whether you even need Kubernetes, and if yes - be ready to invest in good engineering support for the platform itself

Most of the required features for any orchestration tool or framework, which is provided by Kubernetes. After understanding all modules and features of the K8S, it is the best fit for us as compared with others out there.

vSphere with Operations Management has a much better way of automating the re-IPing of servers so you can stand them up in a different environment or location. You do, however, need another way of replicating your servers to your DR site, VSOM will not do that. We used EMC Recover Point for replication.

• Because of microservices, Kubernetes makes it easy to find the cost of each application easily.
• Like every new technology, initially, it took more resources to educate ourselves but over a period of time, I believe it's going to be worth it.

Incentivized

• In the case of a disaster, the ROI would be substantial.
• The license for VSOM is pretty expensive initially.
• Support for VSOM is terrific.
