OpsWorks in Action

1. A Static Application

2. Add a DB layer

3. ELB + Auto Scaling

1. Static Application : Architecture

1. Static Application Setup

a) Create a Stack

b) Add Server Layer

c) Add an Instance to the Server Layer

d) Create App

e) Deploy App

1.a) Static Application Setup : Create a Stack

1.b) Static Application Setup : Add a Server Layer

Layer Type

ELB

Each type of layer has different options ( related to application version).

1.c) Static Application Setup : Add an Instance to the Server Layer

Instance States

Requested - OpsWorks has called the Amazon EC2 service to create the EC2 instance.

Pending - AWS OpsWorks is waiting for the EC2 instance to start.

Booting - The EC2 instance is booting.

Running_setup - The AWS OpsWorks agent is running the layer's Setup recipes, which handle tasks such as configuring and installing packages, and the Deploy recipes, which deploy any apps to the instance.

Online - The instance is ready for use.

1.d) Static Application Setup : Create App

1.e) Static Application Setup : Deploy App

lDeploy multiple apps

lA new server in same layer would have all existing apps deployed

lA new app needs to be deployed on all servers.

2) Adding a Data Store : Architecture

2) Adding a Data Store : Adding a layer and instance.

a) Adding a layer and instance.

b) Application/DB Configuration

c) Deploy

2.a) Adding a Data Store : Adding a layer and instance.
