Likelihood to Recommend I think nowadays, Amazon EC2 is best-suited for most app development and deployment use cases, especially if your resource requirements are not fixed over a long period of time. The flexibility provided by the on-demand pricing and rescaling option makes Amazon EC2 a great service, especially if your tech stack already runs on AWS. On the other hand, I think Amazon EC2 is not the best option if your tech infrastructure runs on another public cloud.
Read full review 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.
Read full review Pros A great variety of choices in Amazon Machine Image (AMI) types. Users can select a more basic type to run generic workloads, but also have the choice to pick an AMI pre-installed with specific services in the AWS Marketplace. The range of instance types can support the usage from a student's exploration (inexpensive general-purpose nano instances) to an enterprise's most intense workloads (memory or storage-optimized instances with terabytes of memory and ultra-fast network connection). The pricing options, from regular instances, reserved instances to spot instances allow users to get the job done and make smart choices about how much they want to pay and when they want to pay. Read full review 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. Read full review Cons This service is a bit difficult to consume. New users need a big learning curve to use this service effectively. UI for EC2 service is a little complex and at many places, it misses detailed explanation. Sometimes it takes too long to create images of EC2 instances. This keeps your EC2 up for that extra time. When instances are heavy, it penalizes a lot of money. Read full review 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. Read full review Usability Amazon Elastic Compute Cloud (EC2) allows various ways of gaining incidents, such as slow growth, money, and the reserved ones, mostly depend entirely on the necessity, because it makes highly intelligent choices possible at these times, which enable considerable cost savings whilst addressing the situation as best I like.
Read full review Support Rating 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.
Read full review Alternatives Considered Azure VM and
Google Compute Engine are alternatives to EC2. AWS EC2 is most matures and advanced of the 3. All these provide easy-to-deploy and automatically configured third-party applications, including single virtual machine or multiple virtual machine solutions.
Read full review 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!
Read full review Return on Investment AWS has had a very positive return on investment for every client we have that uses it. They are saving money in the long run. AWS includes the underlying operating system licenses with their EC2 instances so no longer do we have to navigate through Microsoft licensing headache. EC2 allows us to easily create a golden image of servers and store them as AMIs. This makes spinning up new servers that need a particular set of software in the future extremely easy and cost-effective. Read full review 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. Read full review ScreenShots
