Amazon Elastic Beanstalk is a PaaS offering from Amazon that allows users to deploy and manage applications in the cloud. It automatically handles tasks like capacity provisioning, load balancing, scaling and application health monitoring. The document discusses the history and services behind Elastic Beanstalk like EC2 and S3. It also provides an overview of how Elastic Beanstalk works, the programming models supported, tools available and a demo of deploying a sample news application using Elastic Beanstalk.

28. Some tricks...
! Easy to create a new environment
! E.g. for testing, staging
! URLs can be swapped
Eberhard Wolff - @ewolff

29. Some tricks...
! Deploy new version on new
environment
! Switch URLs with production
! Zero downtime
Eberhard Wolff - @ewolff

30. More tools
! All web console action also possible
using SOAP Web Services
! Command Line tools
Eberhard Wolff - @ewolff

31. Eclipse Plug In
! Manage all AWS resources (EC2,
S3…)
! Manage Elastic Beanstalk server just
like local servers

33. FLEXIBILITY
Eberhard Wolff - @ewolff

34. Flexibility
! Tuning possible
! E.g. JVM parameters
! Load balancer configuration
! Can even use your own system images
! i.e. can add software, fine tune …
! Can log into running servers
! Session handling can be tuned
! Use EC2 if Elastic Beanstalk not flexible
enough
Eberhard Wolff - @ewolff

35. Configuration Files
! Part of the deployable artifact
! Declaratively install packages &
libraries
! Configure software components
! Run commands
! Set environment variables
! Create users & groups
Eberhard Wolff - @ewolff

36. PLATFORM AND OTHER
SERVICES
Eberhard Wolff - @ewolff

37. Platform
! Amazon Web Services
! Proven foundation
! Used for many other cloud plattforms
! …and by many users
! Includes monitoring
! No additional charges to EC2 / S3
! Free tier (750 h/month for one year)
available
Eberhard Wolff - @ewolff

38. Other Services
! Amazon Relational Database Service
! Oracle, MySQL, MS SQL Server
! Diverse NoSQL solutions
(e.g. DynamoDB, SimpleDB)
! Lots of AWS services (Map/Reduce,
Caches, Search etc)
! Other services provided by 3rd parties
Eberhard Wolff - @ewolff

39. Amazon Elastic Beanstalk:
Highlights
! Proven foundation
