Firecracker vs. VMware vSphere

While deploying workloads in lightweight microVMs presents a couple of perks, Firecracker may not be the best software to handle this. Startup times are slow and scalability is quite limited because of the jailer and virtualization barriers. We have had security breaches on isolated EC2 instances while using Firecracker. It however has a silver lining by improving how serverless functions in container ecosystems are run with their VMMs.

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.

Incentivized

• It makes it easy to secure virtual machines as they are segmented into microvms with a minimal attack surface area

Incentivized

• vMotion that provides seamless movement of Virtual Machines between physical hosts and datastores.
• Ease of Manage: vCenter provides very good management experience to the users.
• It provides hassle free upgrade of versions, which requires good planning.
• Easy to manage datastore, networks, CPU and memory resources.
• It also allows to convert the physical machine and bring it to vSphere Environment with minimum effort.

Incentivized

• Excludes devices unnecessarily
• Has a slow startup time the basis being to improve security which is quite irrelevant.
• It has limited functionalities on monitoring VMs despite being an open source.

Incentivized

• Allow enable EVC without requiring host shutdown
• 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.
• Allow searching tasks or events

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 a highly documented suite. If you are unsure of how to do something, a simple search will yield hundreds of results showing you how to do it. Support is also available if you need to talk to an expert.

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

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.

• Low memory overhead on each microVM
• We can run workloads from different customers on the same machine.

• 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.
