More suited I will say deploying your Web-server, Running some cloud applications, Deploying your micro-services, Managed database. Less suited is really hard to say but there can be some scenario where you can use free services like Google spreadsheet scripting for smaller data management and small workflows. Workflow automation is something you need multiple vendors to talk to each other at that time its preferred to go for something else.

VMware ESXi

ESXi excels at providing stable, highly-available resources for most applications. The vast majority of workloads can be virtualized without a penalty. Hardware accelerated assistance is exposed and effective, and the options are plentiful. Adding memory or compute resources is dead simple. Pooling of resources and defining resource priority is top notch. A key to succeeding with ESXi is to give it more than it needs - more memory, more CPU, more network bandwidth. ESXi will manage those resources effectively so long as you give it room to work.
However, with high-transaction databases and some latency-sensitive applications, ESXi may not be the best solution. I've encountered long snapshot times that have disrupted SQL operations when I/O is frozen to create the snapshot. VMware has documented this and actually recommends avoiding snapshot technology in these situations. While not a common scenario this can result in unexpected production issues without thorough, careful planning. ESXi is also not suitable for devices or environments where outboard hardware (USB and other devices) are required. Lastly, the floppy drive has been dead for years. Why is it still present in the default hardware for a virtual machine in the year 2020? Does anyone actually have a need for floppy emulation?

Pros

Amazon Web Services

  • What I like in it, is its simple notification service which provides a mobile messaging feature to enable push messaging to my mobile devices as well.
  • It helps in sending out notifications to all my teammates with full integrity.
  • Responsive Support.
  • Offers a variety of features that help to manage my workload.

VMware ESXi

  • ESXi makes management of hosted machines easy. Everything is in one place. If you have a vCenter (which costs extra) to manage all your ESXi hosts, then everything is truly in one place and there is no need to hop around from management tool to management tool. Al the virtual machines' hardware settings, OS information, storage volume information, backup information, even a remote console just like a KVM ... all of it is in one place.
  • ESXi balances workloads well when using vCenter. Behind the scenes, the vCenter allows an ESXi host to "talk to" other ESXi hosts and when one VM has resources usage that gets past a certain threshold, it can move virtual machines around to balance workloads, even while the machines are running and service users. It's completely invisible to the users, who don't experience latency or any kind of interruptions when their VM is being moved.

Cons

Amazon Web Services

  • If there is one thing I think AWS needs improvement on, it is the administration dashboard. It can be a nightmare to use especially when trying to access billing. This could be made better, honestly, as there should be a simplified way to access simple admin features.
  • While AWS was fairly easy to integrate into our solutions, it is not as easy to use without some IT knowledge. The dashboards are complicated and designed for someone who is computer savvy. If you are just want to keep track of billing, for example, you may need to take a course or spend a few hours with someone being walked through the admin console.
  • AWS does tend to be slow at times. If you do not have a fast internet connection, it can take time to access services that are hosted on AWS. This is not always the case but we have had clients complain about this if they are trying to access a service from multiple points (IP addresses). The only real fix we found was to make our files cache to another server and only keep current data accessible to clients.

VMware ESXi

  • I would love for some of the features only available within the upper tiers of ESXi licensing to be available for Standard licensing purchases. There is a vast difference between free, standard, enterprise plus licensing.
  • The learning curve might be an issue for some users, but can be overcome with the vast amount of resources available. You might have to train to find all of the resources as well.

We are almost entirely satisfied with the service. In order to move off it, we'd have to build for ourselves many of the services that AWS provides and the cost would be prohibitive. Although there are cost savings and security benefits to returning to the colo facility, we could never afford to do it, and we'd hate to give up the innovation and constant cycle of new features that AWS gives us.

Me, not likely as my current company doesn't use it nor do I use it at home. However, I don't see my previous company ever switching away from it.

We find it quite easy to use. The only challenge is at the outset figuring out exactly what you need, given the large number of available services and options which could take a bit of time to get familiarised with and to decide on.

The interface is fairly intuitive for most things, and the areas that are a little less obvious usually have fantastic documentation in the online knowledgebase. In 3-4 years of managing our ESXi hosts, I think that I have only opened 4-5 support cases for things that I could not figure out myself or find answers to on the website.

Performance

Amazon Web Services

AWS does not provide the raw performance that you can get by building your own custom infrastructure. However, it is often the case that the benefits of specialized, high-performance hardware do not necessarily outweigh the significant extra cost and risk. Performance as perceived by the user is very different from raw throughput.

Amazon Web Services boasts a really quick and helpful support with multiple communication options as well. For instance, on my personal account I incurred a minor charge due to mismanagement of a service. Upon contacting support, they quickly explained the issue to me and upon request waived the bill as a first time error.

We have had a bit of trouble with support over the last couple versions of ESX. To be fair, some of the issues coincided with a change from detached storage to VSAN. We have had some system level problems (the good news is that we really don't need much normal support) that they have struggled to fix and that support has been slow to respond to and or be proactive to any degree in these issues. Like many companies that I've seen grow so large, this seems to be just what happens.

Alternatives Considered

Amazon Web Services

Amazon Web Services is well suited when we have a huge amount of data to store, process, manipulate and get meaningful information out of. It is also suitable when we need very fast data retrieval from the database. They provide a superior product at a fair price which allows us to further our goals and push the limits of what we are capable of as a team / company.

We have adopted Nutanix Acropolis as a replacement for our NetApp and a long term replacement for VMWare. VMWare will be interoperable with Nutanix in the near future as a datastore to allow us to slowly migrate to Acropolis or continue to utilize VMWare. VMWare is definitely more full featured than Acropolis however there are some things that are not necessary in VMWare(such as VSan) that are completely built in to Nutanix by design. The Nutanix web interface however is much more responsive.

Return on Investment

Amazon Web Services

  • AWS has lowered our employee cost, because you don't have to hire Network/Server Admins to manage infrastructure.
  • Increased productivity by incorporating Continuous Integration with AWS and our development life cycle.
  • Increased customer confidence by being able to provide HIPAA level security in our development and production environments

  • While using VMware ESXI for our virtual infrastructure hosts, we have had a little downtime, and the VMware ESXI system has caused none of the downtimes.
  • The VMware ESXi hosts have also been able to recover well when there have been unexpected power failures to the kit. This has been very valuable as in the past, we have lost servers when this has happened.
