Overall Satisfaction with VMware ESXi
VMWare ESXi is the backbone for my entire company's North/Latin American environment. It addresses central administration issues as well as an overall ease of implementation as well as shared resources. Also, it helps supplement huge costs for physical hardware that would be required for the 4000 + servers we use to perform the company's daily functions.
- Provides central administration and has amazing stability. You can manage entire data centers from one VCenter interface rather than physically having to manage hardware.
- Allows for shared resources and shared management throughout. Several beefy hardware servers can act as hosts where many smaller servers (vm's) can share its resources.
- Cuts down costs associated with physical hardware needs.
- The VSphere Web Client. Due to it being a web based client, there are still bugs with browsers as well as issues with response times and slowness when manipulating and completing tasks.
- vCenter HA. This is supposed to be an added feature for the next release of ESXi. However, up to this point, it has not been a plausible option and could really be used in large environments with multiple vCenter environments.
- Support. There have been multiple cases where there were bugs that VMware support did not have fixes.
- Positive return on licensing investment and use of features as compared to cost of operations and physical hardware needs.
- Positive return on productivity with ease of management when issues arise with OS and application related problems.
To me, VMware ESXi is the ONLY solution. No others have held up as of yet.
VMware is just about well suited for all environments that have more than a handful of physical servers. However, it all depends on budget as the licensing can be pricey depending on the needs of the company and the features included with each type of license.
