ROI

Sentiment score
7.8
Citrix XenServer offers cost savings and enhanced efficiency through virtualization, justifying the investment despite higher initial costs.
Sentiment score
5.7
VMware ESXi saves time and money initially but may result in higher long-term costs despite improved efficiency.
My clients generally maintain their Citrix infrastructure without shifting, suggesting stability and reliable operation as Citrix XenServer is fully established.
 

Customer Service

Sentiment score
4.8
Citrix XenServer's customer service varies in effectiveness, with challenges in response times and support access, especially for complex issues.
Sentiment score
7.8
VMware ESXi support is responsive and effective, but some users note delays post-Broadcom acquisition, affecting satisfaction.
With valid licenses, we can access hotfixes, service packs, knowledge base, self-help tools, diagnostics, downloads, live chat, and phone support.
They do not provide adequate support for midsize businesses.
There appear to be very few engineers at Citrix who understand the problems.
I rate the technical support from VMware as nine or ten out of ten.
In the last three or four years, we did not require any support from VMware engineers, indicating its high reliability.
Customer service and support are good; they are reachable, and at times remote support suffices.
 

Scalability Issues

Sentiment score
7.9
Citrix XenServer offers effective scalability and integration, appreciated for its ease, cost-effectiveness, and support for enterprise growth.
Sentiment score
7.9
VMware ESXi offers scalable solutions, efficiently managing virtual environments with excellent vertical scalability, despite some licensing challenges.
Familiarity with Linux can enhance its performance and usability.
The solution is scalable, allowing us to scale up or down regardless of infrastructure size.
vCenter Server can manage up to 1,000 ESXi servers within a single UI interface, allowing extensive deployment and management capabilities.
My customers are highly satisfied with its scalability.
 

Stability Issues

Sentiment score
7.7
Citrix XenServer is reliable for SMBs, supports high uptimes, but may occasionally face minor issues, especially with backups.
Sentiment score
8.5
VMware ESXi is praised for stability and reliability, with most users rating it highly despite occasional performance issues.
ESXi is stable, and our business operations depend on it year after year.
 

Room For Improvement

Citrix XenServer needs better backup, integration, management, stability, compatibility, affordability, technical support, community engagement, and marketing.
VMware ESXi requires simpler licensing, improved usability, cost reduction, enhanced support, better scalability, and features like remote access.
Although the product is technically competitive, it is not widely known or used due to poor marketing.
Citrix needs to improve the hypervisor, specifically in security and performance.
We can implement high availability and live migration with pools, along with security and backup to enable role-based access control for safer management.
Providing a mobile application for remote access to ESXi servers would be beneficial.
It's not cost-effective for small users and creates a gap for alternatives, while favoring larger clients.
The cost of VMware ESXi is very high, especially after the acquisition by Broadcom, which led to price increases.
 

Setup Cost

Citrix XenServer is a cost-effective alternative to VMware, though pricing can be complex and varies with needs.
VMware ESXi is often seen as expensive, with high initial and annual costs and a confusing licensing model.
It is cheaper compared to its competitors.
Organizations save substantial money because competing solutions, such as VMware, cost double or triple.
The pricing and licensing policy of Citrix XenServer is not transparent and quite confusing.
The product is very cost-effective, though not fixed, as pricing tends to fluctuate over time.
The solution is moderately priced, not exactly cheap yet not overly expensive either.
The pricing is expensive, with the cost for customers ranging from $10,000 to $20,000 yearly.
 

Valuable Features

Citrix XenServer offers virtualization, ease of use, scalability, and strong support, ideal for small to medium businesses.
VMware ESXi is highly regarded for its reliability, user-friendliness, resource optimization, and efficient management of virtual machines.
The most valuable feature is transferring and sharing applications that allow users to move files between devices, including smartphones, tablets, and computers without needing USB cables, internet connections, or data usage.
It provides secure access to applications and resources, which is crucial for us and our clients.
It is user-friendly and easy to deploy, making it an attractive option.
Its capability to move virtual machines to physical machines is very efficient for our live environment.
As a level one or bare metal hypervisor, its unmatched scalability depends on underlying hardware, capable of managing large numbers of physical servers with one management platform.
The most important features are having a lot of code and CPU threads to ensure the system doesn't lag.

VivekKumar10 - PeerSpot reviewer
Cost efficiency enables significant savings but improvement in support and backup integration is needed for enhanced reliability
In the past, we utilized the live migration feature in Citrix XenServer, but not in this project. This is a new, fresh deployment, so there is no live migration. The support of heterogeneous resource pool in Citrix XenServer depends on the deployment and customer requirements. If a customer requires heterogeneous deployment, we accommodate that. Generally, Citrix XenServer goes in straightforward vanilla deployment because it is majorly used for Citrix farms. Very few customers use it for other products or applications. Intelligent performance optimization is available in this product, but very few customers use it, and those who do aren't using it extensively. I cannot comment extensively on this feature at present.
Syed Ali Waqas - PeerSpot reviewer
Efficiently manages development environments with robust network integration
I recommend new users download and evaluate the free version from VMware's website. Once satisfied, they should purchase the professional version for a smooth and secure IT infrastructure. The professional version is cost-effective, allowing one to create multiple servers on a single server. I'd rate the solution ten out of ten.
