HISTORY & ORIGIN


History & Origin ! Amazon: cloud pioneer ! Original offerings ! EC2 Elastic Compute Cloud ! S3 Simple Storage Service ! Many other offerings ! E.g. databases, Map / Reduce … ! Foundation for many other services


Other Amazon Services ! Elastic Load Balancer

! Auto Scaling starts new EC2 instances

! EBS: Elastic Block Storage virtual hard disks


Elastic Beanstalk in a Nutshell

Programming Model ! OpenJDK + Tomcat

! Standard Java Programming Model

! Also supported: Python, PHP, Ruby, Node.js (Linux), .NET (Windows Server 2008R2)


Scaling / High Availability ! Servers automatically started ! Auto Scaling

! Failed servers will be restarted ! Servers can run in several data

centers


TOOLS


Web Console ! Web UI

! Wizard to create new application ! + environment to run the application

on

Code Changes Took the Spring application Converted to MySQL <bean class="java.net.URI" id="dbUrl"> <constructor-arg value="#{systemEnvironment['JDBC_CONNECTION_STRING']}" /></bean><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="url" value="#{ 'jdbc:mysql://' + @dbUrl.getHost() + " ':' + @dbUrl.getPort() + @dbUrl.getPath() }" /> <property name="username" value="#{ @dbUrl.getUserInfo().split(':')[0] }" /> <property name="password" value="#{ @dbUrl.getUserInfo().split(':')[1] }" /></bean>


Some tricks... ! Easy to create a new environment

! E.g. for testing, staging

! URLs can be swapped


Some tricks... ! Deploy new version on new

environment

! Switch URLs with production

! Zero downtime


More tools ! All web console action also possible

using SOAP Web Services

! Command Line tools


Eclipse Plug In ! Manage all AWS resources (EC2,

S3…)

! Manage Elastic Beanstalk server just like local servers


Eclipse Plug In


FLEXIBILITY


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


Configuration Files ! Part of the deployable artifact ! Declaratively install packages &

libraries ! Configure software components ! Run commands ! Set environment variables ! Create users & groups


PLATFORM AND OTHER SERVICES


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


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


Amazon Elastic Beanstalk: Highlights

! Proven foundation ! Standard Java stack (Tomcat +

OpenJDK) ! World wide availability (incl.

Europe) ! Lots of additional services
