Featured Reviews

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.
Youssef-Hmani - PeerSpot reviewer
IT Infrastruture Consultant at Devoteam Management Consulting
Proactive monitoring has improved infrastructure visibility and simplifies long term management
I remember when I was working as a consultant and implemented Site Recovery Manager from VMware. It was working fine and is a very good solution. Although I used it five or six years in the past, it is very beneficial for customers as a function to build disaster recovery.
