And upgradable read write lock for go

UpgradableRWMutex is an enhanced version of the standard sync.RWMutex. It has the all methods sync.RWMutex with exact same semantics. It gives more methods to give upgradable-read feature.

The new semantics for upgradable-read are as follows:

• Multiple goroutines can get read-lock together with a single upgradable-read-lock.
• Only one goroutine can have a write-lock and no read-lock/upgradable-read-lock can be acquired in this state.

			ticker.Stop()
			return

S3

• By default all new buckets are private
• You can have bucket policies and ACLs (ACL can go down to individual objects)
• Read after write consistency for puts of new objects
• Eventual consistency for overwrite PUTs and DELETEs
• Storage classes
  • S3 standard (99.99 availability, 11 9s durability) can sustain loss of 2 facilities concurrently
  • S3-IA lower fee than S3 but you are charged a retrieval fee (99.9% availability)
  • S3 One Zone - IA lower cost option if you don't need multi AZ data resilience (99.5% availability)

• S3 Intelligent Tiering
