So PVS and MCS are equivalent to VMware Composer..
How PVS differ from MCS  using the Analogy of VMware. I have done some reading about PVS and MCS , could not get real difference since I am much more familiar with VMware than Citrix...
Can someone describe the difference between PVS and MCS using the analogy of VMware ?

Correct.

Did you watch the videos ? The comparison is shown?

PVS is an old technology requiring different infrastructure, it's based on PXE boot (network) for provisioning. This technology has been around for many years, we've been using this sort of technology for use with thin clients, boot PROM networking boots from OS etc

MCS was created in 2010, and is similar to VMware's approach with Composer and the use of Linked Clones, it's integrated into the product, uses space saving technologies. e.g. space reclamation, and uses cache based technologies.

I was reading the blog in the above Link, and they put a diagram (the second one down the page):
http://i0.wp.com/www.barryschiffer.com/wp-content/uploads/2014/06/PVSvsMCS_2014.jpg

Per the Diagram,
PVS is required if:
- the Target computers are Physical
 -Citrix Version is previous to Xendesktop 7
- Storage Based Read Cache is not used (I have no idea what it means)
- Multiple Image Location is used (No idea what it means)

MCS Can be used:
- If Target computers are Virtual
- Xendesktop 7 or newer version is used
- Storage based read cache is used (No idea what it means)
- Multiple Image Location is not used (No idea what it means)

**I believe the article did not mention that PVS needs a dedicated Machine..

MCS technology is like cloning a device automatically within VMWare.
This use a Master image/snapshot from the hypervisor and create a linked clone for every new device.

PVS uses a master-image existing as VHD file at the PVS server and provide this image via LAN boot to the clientdevices.
This clients can be VM's (desktops or servers) and physical devices too. These devices don't need an own HDD (or vHDD) for booting.
because LAN Boot can collide with other LAN-PXE services (MS SCCM, Acronis, PXE) it is not a bad idea to use separated LAN for PXE traffic.

often i prefer PVS because it is more fast than MCS and the versioning of images and the rollback to a previous image is more simple.  
But creating the initial image and the first transfer to PVS server is more complicated.

... and at some little environments it is an advantage i don't need a storage with PVS

I guess the link above will apply to recent version of citrix:
Xenapp/Xendesktop 7.6

I opened up Citrix studio and saw the policy mention in the link above.
UPClient , I believe is installed by default when you install Citrix Xenapp/Xendesktop 7.6, so there is no need to configure it.

----Youtube video I posted above , I guess it is for older version of citrix
