Eco4Cloud Workload Consolidation is a Virtual Infrastructure Optimization Solution designed to improve the economics of virtualized data centers with an intelligent software platform, which increases performances and decreases costs.
Eco4Cloud Workload Consolidation works on top of a virtualization platform, and uses the exposed API to connect to the platform and optimize the workload placement in a virtual farm in order to make it more…
DaaS is ideal in large-scale environments that require centralized, secure management. Remote workforces at large organizations. Highly regulated industries like finance. It allows for easy security and monitoring over one aspect instead of multiple remote machines. DaaS is not ideal for organizations with small budgets due to the pricing and organizations with lousy network connectivity. This would make the end-user experience terrible.
Eco4Cloud is well suited in VMware farms that have standard VM deployments, especially with small VMs, with nothing blocking vMotion and hardware fully compatible with IPMI 2.0 (minimum). It doesn't work well if many VMs are nodes in a Microsoft cluster because they would be unmovable and therefore their host would never be put in stand-by mode. If every host in the cluster has at least one guest VM that is a node of a Microsoft cluster, no host in the cluster will ever be put in stand-by mode.
It consolidates workloads in VMware clusters using an algorithm that seems to work better than VMware DRS. It keeps headroom for workload peaks and to withstand the number of host failures set for the cluster in vCenter.
If the workload is very variable, Eco4Cloud will not continuously turn a host on and off but it will settle to keep the host running. It sort of "rightsizes" the cluster keeping only the right number of hosts running. This is another main difference when comparing Eco4Cloud with VMware DRS/DPM which strictly follows the workload and sometimes isn't fast enough in turning on the hosts when the workload is ramping-up.
To do a good job Eco4Cloud needs to analyze the hosts and the VMs. Therefore, the troubleshooting component of Eco4Cloud can figure out if there are problems in the configuration of the hosts (e.g. vMotion settings). It can also determine if a VM is stuck and can't vMotion (e.g. using the physical CD-ROM) or if it's oversized or undersized.
Something Eco4Cloud has and others don't is a technology named Smart Ballooning. With Smart Ballooning Eco4Cloud recovers unused RAM from the VMs and gives it back to the host way before the host goes over the 94% RAM threshold. This allows us to reach higher levels of overbooking.
Getting the environment setup took me three months of off and on work, with 3 complete rebuilds of the environment. Utilizing the WebUI to access the environment had presented so many random issues that we had to require end users to use the Citrix Reciever App. As it was the only stable solution. Aside from that, it hasn't required much admin intervention since the stand-up was completed.
The performance of XenDesktop is the best in the industry because of the fine-tuned protocol and years of updating. Overall, I don't think there is a better performer on the market. The question is if the added complexity of running XenDesktop is really worth the performance gain. While the latest version of XenDesktop is the easiest to deploy so far, it is still more challenging than the competitors.
The support is great when you get an engineer that knows what they are doing but getting that individual sometimes takes a while. Overall, they are professional and polite and competent in their knowledge. Sometimes the cases are open for an extended period of time which becomes very frustrating when dealing with critical issues.
Take it slow and read the directions each step of the way. If you are not familiar with Citrix products, use a reseller or other experienced engineer to assist you in the setup of your environment
Citrix Virtual Apps & Desktops is platform agnostic (we can use any underlying hypervisor technology) and really flexible for any use case. Using a golden image and provisioning it (with Machine Creation Services or Provisioning Services) is powerful and really straightforward, compared to the complexity in Microsoft RDS of maintaining a coherent farm, or the limitation of VMware Horizon to run on VMware Products.
We compared the consolidation feature and we obtained exactly the same amount of servers in stand-by. The main difference was that Eco4Cloud turned off the unneeded hosts in 2 days while VMTurbo Operations Manager required one day per host. This behavior is caused by the different algorithms implemented by these two products. Compared to Eco4Cloud, VMware DRS/DPM was very aggressive (we tried it in vSphere 5.0). We haven't tested it with vSphere 6 yet.
XenApp has allowed us to continue support of legacy applications and all access of those applications to users across the globe with any device.
XenApp can also manage software licenses by restricting number of users, number of concurrent sessions, or combination of both to required specification.
While initial investment in XenApp can be costly, continuing support and upgrade are very cost effective and product stability is excellent.
While there are competing products from Microsoft and VMware, when it comes to remote application access, XenApp is the best of breed.
