Kubernetes vs. StarWind HyperConverged Appliance (HCA)

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.

As a nonprofit, we needed a virtualization platform that was reliable, cost effective, and simple to administer. StarWind HyperConverged Appliance checked all the boxes for us. We went with their refurbished models to lower the cost, and they've been rock solid. We were able to simplify our environment and the platform has been so reliable that I really don't have to think about it. This has been great for me as the sole sysadmin. There are a lot of pieces to manage, and StarWind HyperConverged Appliance have allowed me to focus less on the platform and more on the VM's themselves and the other pieces of our network environment. I think as long as you get the "right size" of StarWind HyperConverged Appliance that this platform could work well for many organizations.

• 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

• It is extremely easy to set up, it comes with most options pre-configured for you. But the support group will walk through your entire setup and migration.
• It is monitored by StarWind 24x7. Instead of issues being reactive with the monitoring I'm hoping things will be more proactive.
• The performance has been outstanding. I think disk was our main limiting factor with our hold hardware.

• 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.

• Support team has slight accent but is not too difficult to understand.
• Emphasis on security can be improved. Things like default passwords were not changed initially until requested.
• Can't really think of much else...If I had to split hairs...on reboots sometimes it took a while to sync with the other node. Max was 30 minutes, but 99% of the time it's 3-4 minutes.

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.

The hardware appliance convinced me. It is also good to use as a product in the box.Experience of the speed and security of the storage and the data on the storage is important.Installation is relatively easy and support is supportive. You are not left alone.Therefore a clear recommendation

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

Overall, the appliance is versatile. It covers the adaptation to all current hypervisors and can be addressed via different protocols. This prepares you for a wide range of uses.Rack mounting is also well thought out. And last but not least, apart from the technical performance, it is also an eye-catcher.

Working with the
support team has been great. Connecting with somebody during and after business
hours has been smooth, and they have always been responsive and professional. I don't have to wait very long to hear back from them when either sending out an email with a question or inquiry or when calling after business hours when we had to shutdown and bring back up the servers due to hurricanes here in Florida.

Literally, while writing this review, I just received an email from starwind saying my VSAN version was out of date due to a recent update coming out and they offered to help me install it. Its just amazing how "on top of it" support is. They'll monitor downtime, reboots, version issues, even the bios firmware on the Dell servers... I can't imagine using any other vendor, they just do it all, and they do it well.

The old saying: Preparation is everything.It should be ensured in advance that the operating system is up-to-date and therefore suitable for the appliance.The recommended network adapters should also be used in the network and the firewall rules adjusted.If this is planned in advance and everything is prepared, then the installation can be carried out relatively quickly.The manuals and the StarWind website are also a very good help.

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.

Scale was a proprietary SAN software/hardware and outrageously high priced. The StarWind HyperConverged Appliance was just Dell servers with VMWare ESXi Hypervisor installed running two Windows Servers virtual machines where the StarWind SAN software is installed on. The only thing that was proprietary for StarWind was the StarWind SAN software

• 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.

• Our CIS software has some poorly optimized SQL logic. Our old Failover Cluster w/ a VNXe3200 SAN would take up to 7 seconds to pull a customer's records up. It now takes only 1-2 seconds. Our front office has been much more pleasant since their install.
• I would only rarely have to interact with our blade switches and VNXe SAN, so I wouldn't necessarily retain the knowledge of how to configure them. Each time I'd need to make a change, I'd have to refer back to my documentation. That's no longer an issue I have to deal with.
• The rack footprint for our cluster went from 14U to 4U, and we were able to achieve it with much less network cabling and with lowered power requirements.
