Amazon Elastic Compute Cloud (EC2) vs. Red Hat Virtualization (discontinued) vs. VMware ESXi

Suitable for companies that are looking for performance at a competitive price, flexibility to switch instance type even with RI, flexibility to add-on IOPS, option to lower running cost with the regular introduction of new instance type that comes with higher performance but at a lower cost.

RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.

If you're looking for the industry standard in server virtualization, I would recommend ESXi. After decades of expertise in the field, VMware continues to provide a strong product, production-ready, with an easy-to-learn interface that allows for quick management along with less costly upfront onboarding and training. Grab the free personal-use license and install in your homelab to start!

• Huge Diverse range of machine shapes are available which cater to our demand.
• Ability to combine the machines and integrate them with any other service in AWS (Ex: RDS, S3)
• Handling performance and scalability using auto-scaling, ELB configuration and high performance machine shapes.

• RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
• Red Hat distribution integration is seamless as it is integrated into the kernel.
• OpenStack support enables more customized VM templates and network configuration control.

Incentivized

• Resource management. The automatic load balancing works very well to ensure no host is taxed disproportionately compared to the others.
• Templates and cloning. It is very easy to set up a template and spin up new servers based on a specific setup. This makes server management very streamlined.
• VM management. The vSphere interface is very easy to use and navigate. Everything is responsive and it works when you need it to. The options are also robust while also being arranged in a straightforward manner.

• The choices on AMIs, instance types and additional configuration can be overwhelming for any non-DevOps person.
• The pricing information should be more clear (than only providing the hourly cost) when launching the instance. AWS DynamoDB gives an estimated monthly cost when creating tables, and I would love to see similar cost estimation showing on EC2 instances individually, as not all developers gets access to the actual bills.
• The term for reserving instances are at least 12 months. With instance types changing so fast and better instances coming out every other day, it's really hard to commit to an existing instance type for 1 or more years at a time.

• 1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
• 2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
• 3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
• 4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
• 5- Engineering team has to be more reactive when new feature is requested.

• VMware ESXi can improve on the UI that is installed on the bare metal machine. The menus can be hard to navigate when looking for simple configuration items.
• VMware ESXi can improve on the stability of their overall hypervisor. There have been a few times we had to reinstall due to corruption of VMware ESXi.
• I would like to see VMware ESXi do better at adding more standard free features in their consumer version of VMware ESXi. For example, having the ability to back up virtual machines is good practice and something that would be very nice if offered in their free version.

It is critical to our business, what started out as a way to do certain functions, it has now become core to ensuring our product is available to our customers and reducing our costs to operate and reduce our recovery time and provisioning servers. Their support is great and the costs to renew is reasonable.

You an start using EC2 instances immediately, is so easy and intuitive to start using them, EC2 has wizard to create the EC2 instances in the web browser or if you are code savvy you can create them with simple line in the CLI or using an SDK. Once you are comfortable using EC2, you can even automate the process.

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.

Without the need to patch the servers with bug fixes and enhancements we whave not experienced any downtime with VMware issues. Even the bug fixes and updates do not cause of downtime as we just migrate the servers to the opposite node and update the one and then move servers back. Very simple and painless.

We do not notice any difference between a physical and virtual server running the same workload. In fact we can scale quicker with the virtual server than we can with the physical.

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.

I can't say enough good about VMware's support team. To an individual they take ownership of the case, provide thorough answers, and follow up regularly. On one occasion, a problem we experienced with NSX Endpoint was escalated to development for a permanent resolution after a workaround was found. In my experience, most companies would have tried to find a way to close a case like that instead of taking it all the way. Most importantly, when production is down and every second counts, they VMware teams understand that urgency and treat your issue as if it were the only one they had to deal with. You can't ask for better.

Jsut read and follow anything your storage provider may require to allow the integration of VMware with storage operations, outside of that VMware jsut works.

Amazon EC2 is super flexible compared to the PaaS offerings like Heroku Platform and Google App Engine since with Amazon EC2, we have access to the terminal. In terms of pricing, it's basically just the same as Google Compute Engine. The deciding factor is Amazon EC2's native integration with other AWS services since they're all in the same cloud platform.

RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!

As long as you're using Nutanix AOS on Nutanix hardware and are paying their software support fees, AOS is a valid competitor to VMware and can save money due to not needing a license and having their server management system built into the base host management system. If you aren't using Nutanix hardware, however, VMWare is in most cases the best way to go. I cannot comment on HyperV, but most IT people I know either use it because they have to (most) or they like it better (not many).

it has been fair and easy to understand. I know VMware is looking at wanting to change from CPU to core pricing so we will see what that looks like when it happens.

We started out with a two-server cluster and adding a third or fourth is very straightforward and simple with no issues. You just need to be aware of the size of your Vcenter Server to handle the workload, but still the resources needed is very minimal

• It reduced the need for heavy on-premises instances. Also, it completely eliminates maintenance of the machine. Their SLA criteria are also matching business needs. Overall IAAS is the best option when information is not so crucial to post on the cloud.
• It makes both horizontal and vertical scaling really easy. This keeps your infrastructure up and running even while you are increasing the capacity or facing more traffic. This leads to having better customer satisfaction.
• If you do not choose your instance type suitable for your business, it may incur lots of extra costs.

Incentivized

• RHEV has provided a positive ROI as our customers are not experiencing as many outages during maintenances.
• We have not experienced any catastrophic failures as a result of vsphere losing connection to the ntp.
• There has been a level of stability in our environment that was not previously experienced with our previous vendor.

• VMWare ESXi licensing is affordable for our business - and the licensing model is simplistic. Not like that of Microsoft with having to keep track of server licenses and CAL licenses for users.
• VMWare ESXi also has hardware-monitoring built-in, so that further saves us money from having to be spent with another vendor.
• As much as I hate the saying "a single pane of glass" does fit for this product. You can manage your servers, monitor hardware status, create and export backup snapshots, manage virtual NICs, connect to various storage devices. We're very happy with this product.
