Amazon Elastic Compute Cloud (EC2)

EC2 is really standing out when a team is committed to the AWS stack and wants to deploy production jobs on the long term. Reserved instances have competitive pricing and in general the reliability is guaranteed. Spot EC2 instances are also good, when a one-time backfill or feature generation workload needs to be performed.For users who want to use a managed service, for example a Hadoop platform, I would recommend going with Cloudera and similar companies to get the best support possible.

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 Elastic Compute Cloud (EC2)

  • EC2 has wide variety of machine configurations. If the intended solutions are memory heavy, CPU heavy, GPU heavy or IO heavy, EC2 will provide proper machine configurations as per the requirements.
  • EC2 has lot of Machine Images to setup OS and required softwares. It also allows you to create the image of your own disk. This facilitates user to stop the EC2 instance without loosing the work. It helps to reduce the bill. The image can be attached again to EC2 to start from the same place from where it was left.
  • Amazon allows different way to obtain instances like on-demand, spot and reserved. Depending upon the need, one can take wise decision to save cost and address the situation in the best possible way.

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 Elastic Compute Cloud (EC2)

  • The UI of AWS is quite hard to familiarize with, along with the infrastructure setup. It's a conglomeration of hundreds of acronyms specific to AWS that must be understood including their minutiae to effectively run a cloud deployment. While AWS' documentation is extensive, their beginner-focused guides could use work.
  • Instances become incredibly hard to manage after a critical mass, forcing companies to create their own management applications to fill the void that AWS leaves. Along with this, AWS' SDKs can be very poorly documented making this task exponentially more difficult.
  • If you lose your SSH key that is released with the creation of the instance, you lose complete access to the server. While I understand the reasoning behind this decision, MFA recovery would be a nice touch.

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.

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.

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.

AWS's support is good overall. Not outstanding, but better than average. We have had very little reason to engage with AWS support but in our limited experience, the staff has been knowledgeable, timely and helpful. The only negative is actually initiating a service request can be a bit of a pain.

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 Elastic Compute Cloud (EC2)

AWS EC2 is the mainstay of several AWS tools, with CodeBuild that includes AWS Cloud9, and CodePipeline, which allow us to work quickly, efficiently, for all the work team, regardless of whether it is remotely or locally, always keeping the progress saved in the cloud. With Lambda it can be compiled at any time in a fast way, with AWS WAF we protect the different connections, since it provides a high level of security, without having to configure too much, in general all the tools work perfectly with EC2, speeding up the development time of the different projects

VMware ESXi

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 Elastic Compute Cloud (EC2)

  • Instance procurement time has become negligible with EC2. Any developer can provision an instance very quickly and companies can move towards automation of CI/CD pipelines and auto provisioning of EC2s.
  • Companies do not have to spend money in managing infrastructures, data centers, staff to manage these, networking, connectivity etc. All this will be taken care by AWS and EC2 can be used to run your enterprise softwares and custom applications.
  • If not correctly monitored EC2 prices can run up very quickly. So proper monitoring has to be in place in your organization. Non-prod and dev EC2 servers should be brought down in evening and night.

VMware ESXi

  • 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.
