Launch a new EC2 instance

Procedure

In Configure Instance, use the following information:

Field	Value
Number of Instances	`1`
Network	Choose `Talend VPC`.
Subnet	Choose `Public subnet eu-west-1a Talend ESB`. For the moment, we launch one instance in only one subnet.
Auto-assign Public IP	Select `Enable`. We will use the public IP to ssh into the instance for further configuration

Leave all other fields as default.

In Add Storage, use the following value then click Next: Add Tags:
- Size = 32 GiB
In Add Tags, add a name tag with Talend ESB - Template - eu-west-1-a for example, and any other relevant tag for you.
In Configure Security Group:
- Select Create a new Security Group.
- Security group name: Talend - ESB Security Group.
- Rules: Add the rules as per the screenshot below.
  - The SSH rule on port 22 allows ssh sessions on the instance for management purposes. AWS Best practices would recommend to only open this port to your IP or corporate directory range of IPs.
  - The Custom TCP Rule on port 8040 allows connections only from the Load Balancer. sg-f41e8992 is the security group name of the AWS Load Balancer we created previously. You may choose secure transmissions (HTTPs or TLS) for enhanced security. These are part of AWS Best Practices.
Click Review and Launch.
Review your Instance configuration then click Launch.
Select your existing key pair or create a new one. Then click Launch Instances.
