GCP: GAE - Memcache best practices

Memcache is a distributed in-memory data cache in front of or in place of robust persistent storage for some tasks. GAE includes a memory cache service for this purpose. Best practices for using memcache: 1. Handling memcache API failures gracefully; Do not expose errors to the end users 2. Use batching capability of the API when possible 3. Distribute load across your memcache keyspace Use sharding and aggregating for improving performance efficiency. Use TTL (expiration policy) to make sure the memcache does not fill-up indefinitely Use getIdentifiable() and putIfUntouched() for managing the values that may get affected by concurrent updates Use batching (getMulti ("comments", "commented_by") ) to fetch related values together instead of one by one Use graceful error handling

RAID Levels: Redundant Array of Independent Disks

Standard RAID levels comprise of configurations that employ the techniques of * STRIPING * MIRRORING * PARITY  to create large reliable data stores using general purpose HDDs. Levels are standardized by SNIA (Storage Networking Industry Association) in Common RAID Disk Drive Format (DDF) RAID 0 >> STRIPING (No fail-over, No Redundancy, Total loss of information if disk fails, each disk size will be of smallest disk size in the set of the disks) RAID 1 and its variants >> MIRRORING (Copy of write will be in more than one disk, Redundancy, less performant) RAID 5 >> Distributed PARITY RAID 6 >> Dual PARITY Source:   Wikipedia
