PrasticeSummary 4. What is Google App-Engine (GAE)? Platform as a
Service (Paas)Allow you build web-app run on Google's
infrastructureMake your development easy, simple, and scaleYou are
in control with nice dashboardIt's not just a hosting service: App
Engine empowers you to designyour app in Googly way! 5. GAE
Environment Build applications with any of environmentExperimental
Experimental 6. GAE Environment : cont. Warning: The App Engine SDK
no longer supports Java 6. Applications that use Java 6 need to be
migrated to Java 7. Existing applications that use the Java 6
runtime are still supported, but this support will be removed in a
future release. The PHP runtime is available as an experimental
Preview feature. Please be aware that the APIs and service may
change before the service becomes Generally Available.

7. Why GAE ?Fast bootstrap Small opeartion Reliability Scalability
More .Help avoid commons isssues with file system, threading, and
timeout request.Interesting with new Technology ? 8. Why GAE :
Runtime ?Helps avoid common pitfalls : file system, time outs and
threading ! 9. Why GAE : Operation ?Easy to maintenance, Managing ,
Monitoring ! All in once place ! 10. Why GAE : Reliability ? 11.
Why GAE : BootStrapping ?Up and Running in hours ! 12. Why GAE :
Scalability ?small to BIG passion 13. Why GAE : Consolidation ?All
in one place ! 14. How to calculate GAE Cost ? - No cost setup and
installation - Cost free to get started with limited resources
(Mem,CPU, requests) - ONLY pay when consuming1 - type of service 2
- system design 3 - quality of usage 4 - supporting service 15. GAE
core services Data storage, retrieval, and search - Datastore -
Blobstore - Search - Memcache - Log Communications - Channel - Mail
- URL Fetch - XMPPApp configuration and management - App Identity -
Capabilities - SSL for Custom Domains - Remote - Multitenancy -
Traffic Splitting - UsersProcess management - Task Queue -
Scheduled Tasks Computation - Backends - Images Ref :

works? Tranditional App Server StructureWhat if you have: Hardware
failures, Traffic Spike, Growing Big Data, No initial fund to buy
all the hardware, No one to design, implement and operate this
complex thing... 17. How GAE App works? 18. GAE Best Prasticse
Design Non-relational data model by Datastore/Bigtable: -
Denormalization : optimize the read performance : 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 -Use pagination through larget dataset : Use cursorKey
rathen than offset and limit - Use Sharded counter : getCount(),...
Memcache is your friend, use it in effective way!For GAE Dev, it's
important to understand how things are working inside the App
Engine structureto get more benefits from these goals 19. Summary A
fantastic service for complex, high availability, scalable service
for demanding customers need -1 fast start-up projects: dev can
make the app in a few hours -2 easy deployment -3 run-time will
support and lead dev. into a good habits while development (esp.
dealing with resources - filesystem, request, thread) -4 small
operation team can manage a large number of service - All in one
place -5 Auto-scaling is nice and reliability as well 20. FAQ!
