Heathrow Airport

!   BAA will update status file for each airport once every 5 minutes using FTP

!   The Ingestion Daemon get all the flights and the related information

!   Updated flights information is send to the Status Service

!   For each flight received from the ingestion Daemon, If the flight already exists it will merge the existing status with the new status, if it is a new status it will added

!   The status service request all arrival and departure flights for a specific airport from FlightStats during the next 14 hours (one single request that can be slow and contain a lot of data)

!   For each of the received statues (from BAA) the service try to find the same flight in the response from FlightStats. If it is found the service will, first update the status with the information from FlightStats and then If the status from FlightStats indicate that the flight have coflights this information will be added to the status.

!   Updated status are stored to be usedfor the next 5 min

How to calculate GAE cost?

1.  Type of service 2.  System Design 3.  Supporting Services 4.  Usage

23

Summary 1

!   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.

GAE is a fantastic service for complex, high availability and scalable service for demanding customers

24

Summary 2

!   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.

Good understanding and strategy for using the datastore is fundamental for achieving a good service
