Citrix

The free version is a boon for small businesses that want to have a hypervisor but not the headaches of using something that requires licensing. It is more than adequate to compete with the lesser versions of Hyper-V or VMware. Any small business that wants to lessen its hardware footprint could benefit from this product. If you are a medium or large business it is also a nice addition to the cupboard if you already use other Citrix products and are familiar with the Citrix support process. Shops that are fully committed to VMWare or MS Hyper-V should probably avoid this as it would just act to dilute your system and add unneeded complexity. Citrix Hypervisor is not most common Hardware Hypervisor on the market but it is more than competent for most Enterprise Deployments.

Red Hat

RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.

Pros

Citrix

  • Resource Monitoring is a good and I am able to monitor my entire infrastructure whether I'm using my iPhone remotely or while on any company-issued laptop to ensure our services run at peak efficiency.
  • CLI - the command line is not hard to use. It can take a little time to get used to the commands but once you have them down managing the environment from the GUI or CLI is pretty easy.
  • Backups are very easy to start and manage with XenCenter or XoA. Keeping business DR scenarios achievable.

Red Hat

  • RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
  • Red Hat distribution integration is seamless as it is integrated into the kernel.
  • OpenStack support enables more customized VM templates and network configuration control.

Cons

Citrix

  • Adding or presenting additional storage to the host can often be a task that is far more involved than competitive products.
  • The product can require reboots more frequently than competitors due to the DOM kernel getting "hung up".
  • Sometimes when a virtual machine is deleted it still leaves behind orphaned vdisks.
  • Recovering from the loss of a host can sometimes cause virtual machines to require lengthy command prompt scripting to fix so they can be powered back on from another host.

Red Hat

  • 1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
  • 2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
  • 3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
  • 4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
  • 5- Engineering team has to be more reactive when new feature is requested.

    With the knowledge and usage of solutions from VMware and Microsoft offering more compelling cloud integrated options it makes it more compelling in many environments which I consult. XenServer is a good product and fits the bill in many smaller environments but as clients look to the cloud or a hybrid cloud it can in some cases make it a bit more difficult.

    Usability

    Citrix

    XenServer is quite usable due to the simplicity the management and installation provide for an administrator. The console for management is very intuitive and can easily be installed on any Windows operating system. There is a relatively simple web console that can be implemented as well that enhances the usability to provide service to non-administrators.

    Reliability and Availability

    Citrix

    It's been a little problematic in the past at larger VDI deployments requiring a bit more care and feeding than other vendors. But the latest releases (6.5.x) have brought about huge improvements in the stability and availability.

    Performance

    Citrix

    When running like a top XenServer is a fantastic hypervisor. There is relatively low overhead on the Dom0 so workloads get the most of the resources.

    Anytime I had to request support from the Citrix Hypervisor website I had an instant answer and it was straight to the point. I also used the forums available to everyone and always had success from both the technical staff and from the community.

    In-Person Training

    Citrix

    Part of a training for certification to become a trainer for Citrix included an in-person training with a Master CCI. The XenServer training at this time was pretty simplified due to the product primarily being installed however you did have to work with it and mildly configure the system.

    Online Training

    Citrix

    Haven't given it a real go with any online training however there are some options out there. I have taught a course following Citrix material for XenDesktop which leverages XenServer and it is pre-built so not the best for XenServer specifically for installation but configuration is mildly touched on

    Citrix

    Ensure you review the HCL (hardware compatibility list) and reach out to the hardware vendors to ensure they support the platform and in case they have documentation that can be followed for the implementation. Also ensure the prerequisites are completed prior to implementation so that as few unexpected delays occur as you can control.

    Alternatives Considered

    Citrix

    VMware seems to be the standard and is more widely accepted. However, Citrix Hypervisor, is easily learned and cheaper. We have also used VirtualBox to offer up ideas for other free products. VirtualBox seems to be easier for end users who just want simple VMs and not necessarily entire environments. Citrix is good for environment virtualization.

    RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!

    Scalability

    Citrix

    The servers latest versions have made massive improvements to scalability. But from past experience there have been issues when running workloads for extended periods of time without reboot on the hosts. I would need to run similar workloads on the 6.5 release which has changed much of the bottlenecks or issues so I'd imagine its far more capable now, Perhaps able to stand near the best in the market.

    Return on Investment

    Citrix

    • Xenserver is easy to learn. We paid for support only for installation and deployment in the first three years, and now our team has the knowledge to solve most problems.
    • Low CAPEX if you have a team that uses open source software day by day.
    • But paid support is necessary to solve critical problems. The open source community is not enough. Actually, we have difficulty solving some bugs without paying for support.
    • Medium OPEX if you have a team that uses open source software day by day.

    • RHEV has provided a positive ROI as our customers are not experiencing as many outages during maintenances.
    • We have not experienced any catastrophic failures as a result of vsphere losing connection to the ntp.
    • There has been a level of stability in our environment that was not previously experienced with our previous vendor.
