An enterprise workload platform, vSphere is used to improve the performance for a data center. It is used to boost operational efficiency, supercharge workload performance, and accelerate innovation.
vSphere simply is best-in-class for its features and functionality. It does guest OS management, thin provisioning, deployment, management, networking, vMotion, and automation better than all the rest. vSphere is always the first to implement new and advanced features and push …
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.
Well suited: development work as they provide a very nice free tier, datacenters in Latin America with very low ping, heavy loads for DB if you use Oracle DB Less appropriate: fast webservers as they use hard disks for several tiers, fast MySQL databases as the server is shared, auto-scaling functionality is not present.
vSphere is well suited for multiple VMWare hosts and can be very useful in larger enterprises where vMotion is used to load balance and failover running virtual machines. In smaller businesses with one or two hosts then the features can be overkill. The addition of virtual TPM support is a very nice addition to provide vm security in a more Microsoft supported methodology.
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.
More detail in recent tasks. Instead of just showing a task called "Reconfigure virtual machine" also have a link to more detailed information as to what was reconfigured, changed or removed.
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.
We are constantly looking for change that will benefit our company. We are not ones to stick with a product simply because it is what we know, but rather looking for what fits us best. We can't imagine another product on the market today doing a better job of handling our infrastructure than vSphere.
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
Very useful for environments where space and energy consumption are issues and management is not very keen on upfront spending on hardware every time whenever requirement comes from any dept for provisioning a machine for their occasional use, easily can be done in case of VMware vSphere in few clicks. Backup, security, monitoring and management everything is covered but at additional cost.
I rarely ever have to contact support and when I do need to resolve an issue, there is always an abundance of kb articles and research information available that can help quickly resolve the issue. Depending on the type of support contract you have, you may get support from some offshore group in another country and this could be a little challenging because of the language barrier.
Just make sure that when you implement, that the person implementing truly knows what they are doing and has a plan of action coming in. Since our initial implementation using a consulting service, I have implemented a few vSphere just from what I learned at the initial implementation and use over time, and the person implementing really needs to know what they are doing or you will miss out on features that may help you down the line
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 has a lot more feature sets than Hyper-V but at a much higher cost of entry versus MS Hyper-V. I have not been able to play with Hyper-V as much as I would have liked, but the setup and ongoing maintenance seems to be easier in vSphere than with Hyper-V
The contract terms are very clear and can be updated as per the project requirement. Customer support is also included in the contract which help us to troubleshoot critical issues very easily. Training included in contract will really help the client team to empower and hands-on on the latest updates and enhancements
As I said earlier, they're always ready to understand our issues and propose the best and most appropriate solution for issues all the time. The security patches solution is accordingly to the business needs. Another scenario is their Knowledge Base where they're many articles that help you in order to solve something which is wrong.
Having vSphere helped my business quickly recover from a ransomware attack which would have crippled us for weeks if we were not virtualized. I think the ROI on something like that is immeasurable.
vSphere has allowed my company to purchase bigger server hardware to host 3 or 4 virtual servers, which was at a cost much lower than buying 3 or 4 server hardware boxes, saving us thousands each time we need to upgrade hardware.
