VMware public cloud

VMware public cloud – is nothing but a VMware hosted cloud for enterprises that can extend the enterprise’s own private cloud. VMware calls it a “hybrid cloud”.  It’s not like AWS or Rackspace.

So if companies are running out of data center capacity and want additional capacity they can resort to VMware provided “vCHS – VMware Cloud Hybrid Service”. The linkage between private and VMware cloud is done by the Hybrid cloud connector.

Network World – Perhaps the biggest selling point for VMware’s newly announced hybrid cloud strategy — and the reason it could be a game changer in the infrastructure as a service (IaaS) market — is because of the common platform VMware customers will now have between their private cloud internal systems and this new VMware-operated public cloud.

XOR Encryption

if A ^ B = C, then C ^ B = A and C ^ A = B.

This is one of the salient features of XOR that allows us to reverse engineer one of the inputs given one input and the output.

A (plaintext ) ^ B (key) = C (Ciphertext)

In encryption lingo, given the key (B) and the ciphertext (C), it is possible to get the plaintext (A)
