Launch instance templates + tomcat 9

You can create a launch template that contains the configuration information to launch an instance. Launch templates enable you to store launch parameters so that you do not have to specify them every time you launch an instance. For example, a launch template can contain the AMI ID, instance type, and network settings that you typically use to launch instances. When you launch an instance using the Amazon EC2 console, an AWS SDK, or a command line tool, you can specify the launch template to use.

The following diagram shows a launch template with three versions.

Amazon Elastic File System (Amazon EFS)

Abstract

AWS Application Load Balancer

Elastic Load Balancing automatically distributes your incoming traffic across multiple targets, such as EC2 instances, containers, and IP addresses, in one or more Availability Zones. It monitors the health of its registered targets, and routes traffic only to the healthy targets. Elastic Load Balancing scales your load balancer as your incoming traffic changes over time. It can automatically scale to the vast majority of workloads.

Elastic Load Balancing supports the following load balancers: Application Load Balancers, Network Load Balancers, Gateway Load Balancers, and Classic Load Balancers.

Application Load Balancer components

The following diagram illustrates the basic components. Notice that each listener contains a default rule, and one listener contains another rule that routes requests to a different target group. One target is registered with two target groups.

README

Let Tomcat is download and installed under /opt/tomcat. Also, let tomcat be a non-provileged user under which the server will be running.

We assume that we keep server's binaries under /opt/tomcat and we will create a server instance named foo under /var/tomcat/ (carrying its own conf, logs, webapps, work, lib directories). See also https://dzone.com/articles/running-multiple-tomcat.

Create a template service unit file at /etc/systemd/system/tomcat@.service:
