Citrix PVS on Azure TP (Technical Preview) Program has been extended till 31st of Oct. 2021, and we know that many citrix enthusiastic like us are spending lot of time in testing this one of the most beautiful product of the Citrix stack. Citrix Product team has released a very good document to kick start you in Azure but that is generally targeted to the users who are already experienced in PVS, if you are new to Citrix PVS technology, this document is going to help you greatly to understand what is the PVS service is and how it works in Azure.
Before we start let’s see few FAQ’s on provisioning services (PVS).
What is the provisioning services (PVS)?
It’s a citrix image provisioning technology. It’s used to provision images to multiple machines from a centrally managed image.
It has a world class streaming technology which allows computers to be provisioned and re-provisioned in a real time from a single shared-disk image.
Is PVS is part of Citrix Cloud?
No, PVS is a complete separate entity, it’s altogether a separate software, it requires separate resources, configurations, maintenance and setup.
What are the benefits of provisioning services?
- It simplifies the management of the enterprise images.
- PVS is demonstratively faster at deploying and rolling back image update compared to citrix MCS.
- It ensures a consistent and secure user experience. VDA’s provisioned using a PVS image, all boot from the same image, which ensure users are getting the same experience from any machine.
- Boot times of PVS streamed VM’s are around 40 secs in Azure.
- Rollback and revert fast: Here the versioning & roll back is instantaneous. Any issues that occur during the run time such as actions of a single user, or malicious attack on a operating system, all can easily be rolled backed by rebooting the machine which will then reboot from the centrally shared image and revert the user experience before that incident occurs.
Reduce storage footprint of your deployment in Azure, Storage requirement are reduced due to several factors as stated below:
- Single copy of Image.
- Target VM has cached disk that is around 25-35% size of the image depending on the workload.
- Better performance compared with On-Premises, because Azure networking is better/newer/faster then any typical on-prem network
PVS is better at streaming disk contents then storage
