5. GDG Granada About Scale • Approximate size of Google's search index? ◦ (2012) • How much video uploaded to YouTube every minute (in hours)? ◦ (2013) • Speaking of YouTube... monthly uniques? ◦ (2013) • How many (HTTP) "hits" does App Engine get across all apps every day? ◦ Stay tuned... • Google ever down? 500s?
6. GDG Granada About innovation

13. GDG Granada Google’s Golbal OpenFlow Network
14. Compute Engine Infrastructure as a Service (IaaS) Virtual Machines, Networks, Storage at Google
15. GDG Granada Compute Engine Debian, CentOS, RedHat, SuSe, FreeBSD, CoreOS Windows Server 2008 Your own custom server Internet Private Network CLI UI Code Persistent Disk Cloud Storage VM VM VM Project
16. GDG Granada Compute Engine Performance Source: Scalr/gigaom.com (May 2013) Real-world Performance Observation
17. GDG Granada Storage Cloud Storage • Fast, scalable, highly-available object store (US or EU) • Strong read-your-write consistency • Easy, flexible authentication & sharing (OAuth2, ACLs) • REST API, App Engine API, Web UI, command-line Cloud SQL • MySQL-compatible relational cloud database • App Engine API or externally via JDBC
18. GDG Granada BigQuery - Large scale query and analysis cloud service - Analysis of massive datasets - CSV or JSON file Directly or using GCS Optionally gzipped - Streaming API Up to 100,000 rows/sec
19. GDG Granada Analysing Large Amount of Data ...at high speed https://demobigquery.appspot.com/
20. Cloud DNS • High performance, reliable DNS service GDG Granada Google Cloud Platform: Services Prediction API • Machine Learning service in the cloud • Supervised learning • Train models, get "predictions" • "Magic?" Possibly Translate API • Translate text into other languages programmatically
21. GDG Granada IDE and Tools App Engine • App Engine SDK • Google Plugin for Eclipse Google Cloud Platform • Google Cloud SDK: gcloud, gsutil, gcutil ◦ Also App Engine • Cloud Web Console Build and test in the cloud (Github repos)
22. GDG Granada Programming Resources http://googlecloudplatform.github.io/
23. App Engine
24. GDG Granada Hardware failure? Traffic spikes? Scaling? Patches & upgrades? Network issues? License management? Building a traditional web application
25. Why does App Engine exist? GDG Granada
26. App Engine to the rescue!! GDG Granada Build and run your web apps on Google’s infrastructure
27. Features GDG Granada Scale Manage Build
28. App Engine GDG Granada • PaaS • Popular Languages and Frameworks* • Focus on writing your app • Multiple Storage • Powerful Built in Services • Familiar Development Tools • Deploy at Google Scale • Administration console • Free quota**
29. App Engine GDG Granada • AppEngine with managed VMs • Default domain: <id-app>.appspot.com • Custom domain* • Suppor for HTTPS & SSL* • Choose from US- or EU-based service*
30. GDG Granada Python, Java, Go, PHP not enough for you?
31. Specialized APIs/Services for the Sandbox Cloud Storage Images Mail Channel Task Queue Memcache Datastore URL Fetch User Service GDG Granada
32. GDG Granada Hardware failure, traffic spikes, scaling, software patches, upgrades handled by Google... and yes, we’ll operate it for you! How does it work?
33. GDG Granada Cloud Storage Cloud SQL Cloud Datastore Storage
34. GDG Granada Datastore • NOSQL database at Google scale • Very fast!! • Familiar native datastore for App Engine • GQL (Google Query Language) • Java and Python support only • Java have the use ORM Framework • GQL can’t execute JOINS at SELECT queries
35. GDG Granada Datastore
36. GDG Granada Datastore Entities • Has a Key and set Properties • The Key has a Kind, an identifier (int or String) and an Ancestor Path (Opt.) • The Properties are set type key-value • Can do Queries about the Entities
37. GDG Granada Datastore
38. GDG Granada Datastore Trick (or treat)!!
39. GDG Granada Datastore Trick (or treat)!!
40. GDG Granada Datastore Trick (or treat)!!
41. GDG Granada Datastore Trick (or treat)!!
42. GDG Granada Datastore Entity != Table • 2 entities from same Kind can’t have the same properties • A property can contain a value or multiple values • Diferent behaviour between a property with value null and a property didn’t inicializate • Indexes
43. GDG Granada Datastore
44. GDG Granada Add, Retrive, Modify & Delete
45. GDG Granada Relation between Entities
46. Remember dev!! GDG Granada • IaaS != PaaS • APIs: Pay-per-use!!! • Limited tools!!! • Doing the wrong things in GAE can be expensive
47. GDG Granada Administration Console
48. GDG Granada Development Cycle
49. Customers GDG Granada
50. Popular App Engine use cases • Mobile/Tablet ◦ App backends ◦ Cloud persistence • Social/Mobile Games ◦ Speed, scale ◦ API integrations ◦ Personals/dating • Consumer Web Apps ◦ Unpredictable traffic ◦ Scale • Apps in Academia ◦ Any course where students build web or mobile apps ◦ Research projects ◦ IT/Operational apps • Business Apps ◦ Enterprise ◦ Java runtime ◦ Web or Mobile
