  24. Summary 1 GAE is a fantastic service for complex, high availability and scalable service for demanding customers !   Super fast bootstrapping and template projects - developer can get up and running in a few hours. !   Run-time will support and lead developers into good habits, especially dealing with resources (files, requests etc). !   Small operations team can mange a large number of services - everything in one place. !   Auto-scaling is nice and important BUT less then the items above. 24
  25. Summary 2 Good understanding and strategy for using the datastore is fundamental for achieving a good service !   Hire or grow an internal datastore champion that can police/help projects. !   Invest in sharing best practices, internal tech talks/workshops to spread the knowledge. !   Denormalise, duplicate properties between entities to avoid an extra read, always use queries that run a list of results, never request single result on a loop. Rule of thumb is to do max 1 read per request. !   Memcache is your best friend, use it well. 25
