Overview

• Tutorial covers basics of using Resin Java Application Server on
EC2 and EC2 like environments
• Setting up Resin
• Doing a cloud deploy
• Setting up Resin Pro license
• Deploying to EC2 box
• Eclipse to create a simple war ﬁle and then deploy it to Amazon
EC2


Resin works well with EC2 and IaaS

• Many Steps in tutorial same for other IaaS solutions
• Eucalyptus, CloudStack with CloudBridge, RightScale myCloud
or even OpenNebula this guide should help you along as they all
support the Amazon EC2 REST APIs.
• Any IaaS cloud computing environment (private or public, on
premises or hosted) very similar steps
• Xen Server, Xen Cloud or VMWare vSphere etc. should be
similar
• Servers not only as a Resin on EC2 environment tutorial but
just a general Resin deployment tutorial


Development boxes

• Local dev box is Ubuntu (could be Linux, Windows, Mac OSX,
but choose Ubuntu)
• Remote EC2 box is Amazon Linux
• Amazon Linux like CentOS
• CentOS like RedHat
• In a way it is a good Resin Linux tutorial that covers Debian
like, and Red Hat like instances
• (Resin runs on Solaris, Linux, Windows, Berkeley and Mac OSX).


Familiar with Amazon EC2?

• If not, start here: http://docs.amazonwebservices.com/AWSEC2/
latest/GettingStartedGuide/Welcome.html (then come back)
• Learn how to start/stop instances, etc.


Amazon WS Console to launch instance


Start up new instance then install Resin

• Fire up an Amazon Instance using Amazon Linux (basically
CentOS 5.4)


Make sure Resin is running


Install Resin on local dev box (Ubuntu)

• Add Caucho's Debian repository to system's repositories
• edit /etc/apt/sources.list
• Add this line


Test Resin setup on local dev box


Use Eclipse to create test war ﬁle


Create a simple servlet


Export war ﬁle


Deploy and test locally


Create an Elastic IP for your AMI

• Amazon EC2 instances are assigned two IP addresses
• 1 public, and 1 private
• The public address is mapped via Network Address Translation
(NAT)
• Every time you start or restart an instance, it gets new public
and private addresses
• This makes it hard to conﬁgure a static cluster topology



• Amazon EC2 provides a service called Elastic IP addresses
• Elastic IP addresses are static IP addresses.
• Elastic IP addresses are associated with your account, not a
speciﬁc instances.
• You can associate an Elastic IP address with an instance.
• It is good to associate your instance with an IP address so you
can direct your calls to that instance when deploying an
application
• Also you need to know some address to conﬁgure the Triad
• (Resin only communicates with private addresses, but uses
public addresses and a secure handshake to exchange private
addresses)


Elastic IP address

• It has to be reassign every time the server starts up
• It has to be assigned to an AMI instance in order to be used


Password and User name

• You can’t execute commands remotely without a username and
password
• To do a remote deploy on Amazon EC2 from your dev box, you
need a user name and password


Create password for your Amazon Cloud


Put user-data with credentials in AMI


Create ec2.xml ﬁle and install it in


Make sure right ports are open


Deploy from command line

• From development box, deploy test hello.war
