I have a big confusion on cloud computing that, how is it managed in terms of h/w allocation, shared storage, fail-over, usage etc so all my doubts are listed below.
1. I have created 2 HyperV servers in a clusture with all VMs stored in shared storage (microsoft iSCSI). If any 1 of my HyperV server goes down, VMs are shifted to other HyperV server. I have also configured 4th server as HyperV replica (Kept in another building)
so if my shared storage, both HyperV or whole clusture goes down i can still start my VMs on HyperV replica. So my question is, is this a private cloud?
2. If above is not a cloud, then What is a private cloud?
3. What is the role of SCVVM in private cloud setup?
4. What is the role ofAzure Pack in private cloud setup?
5. SOMEONE told me that my setup (1) is not a cloud. Its just a HyperV cluster and I should create a cloud because cloud has the capabilities to merge computing, storage and RAM capacity of all members of the cloud, like that if 1 want to run a VM with 16 GB of RAM, then cloud can give 8GB RAM from 1 HyperV server and another 8GB RAM from 2nd HyperV server and if my 1st HyperV server goes down, cloud will shift that lost 8GB RAM to 3rd HyperV server but my VM will get 16GB of RAM in any situation. Same is for disk. I dont need any shared storage to create a cloud, If 1 storage server goes down, then my VMs will start running from another server because cloud keeps data InSync to all the member servers. Same is the perception for processor so, IS THIS THE PRIVATE CLOUD ??
All que/doubts i talked above is for Operating system virtualization.
Can someone please clear it. I searched for all doubts but didn't got Insight. May be, because of less understanding on this topic.
Thanks, Rishi Pandit.
