Geert Vandevelde - PeerSpot reviewer
ICT Diensthoofd - Head of ICT at Azwest
Consolidating user access boosts productivity by simplifying navigation
The most helpful features of Citrix XenServer are that you can consolidate everything onto one web page. For our use case, this is probably the easiest solution because there are many different software applications running in our environment. The benefits from using Citrix include increased productivity, as users don't have to search for what they need to open. They can see everything in one place instead of having numerous links in Chrome or on their home page. They simply go to our Citrix page and see everything they need. We can also specify access permissions per user, so they only get the software they require. If users have lists or reports they need to create, we can add the icons on Citrix, and they can open them directly. Everything is in the same place, so they don't have to search for anything anymore. This is the biggest productivity increase.
Gourab Das - PeerSpot reviewer
Senior Manager at a financial services firm with 1,001-5,000 employees
Virtualization has transformed our data center and delivers consistent uptime with seamless maintenance
The most valuable feature VMware ESXi offers me is the user interface and the ease of handling operations without downtime, which is the biggest advantage, particularly with capabilities for live patching, and VCF 9 in patching areas; the bundled licensing provided simplifies management as I can utilize resources based on my needs without worrying too much about individual licenses. The zero-downtime patching is the feature that makes the biggest difference in my day-to-day operations, as well as managing hosts with an n+1 configuration, using a buffer host to streamline maintenance within a cluster of hosts. The vMotion feature is another important aspect, as we opt for auto vMotion to optimize resources within the cluster, enabling the underlying VMs to be moved seamlessly from one host to another based on utilization without impacting applications. VMware ESXi has positively impacted our organization significantly in terms of operations and cost optimization, as we optimized our environment under a per-core license agreement, achieving around 30 to 40% cost-effectiveness and maintaining almost 99.99% uptime across our environment, where VMware ESXi is run on about 85% of our setup. Improvements in operations were made possible through visibility provided by VMware ESXi into hardware enhancements, such as virtual storage platforms with vSAN, which we incorporated into our environment supported by VMware ESXi 9 to enable effective live patching without impacting operations, and we regularly utilize RV tool reports to track actual utilization and optimize resources, reducing our footprint from 100 VMs on 100 hosts to 47 hosts, yielding substantial financial benefits thanks to the support from our VMware ESXi TAM.
