Scaling Up

In case of an increase in traffic load, CloudFormation and the Zend Server cluster will automatically add instances to the deployment, apply cluster configurations, and deploy applications:

1. The High CloudWatch alarm identifies an average high CPU usage for the Zend Server instances in the Elastic Group of over 90%.
2. A notification is sent to the operator email defined in the template, reporting the status, and the Scaling Policy is triggered to scale up the Elastic Group.
3. The Elastic Group scales up by starting a new Zend Server instance.
4. The new Zend Server instance receives cluster PHP and system configurations according to teh blueprint existing on the MySQL database.
5. All deployed applications in the cluster are deployed on the new Zend Server instance.
6. The new instance is added to the Elastic Load Balancer.

Scaling Down

If there is a decrease in traffic load, CloudFormation and the Zend Server cluster will automatically handle the scaling down of the deployment and ensure high availability with a graceful shutdown of instances:

1. The Low CloudWatch alarm identifies an average low CPU usage for the Zend Server instances in the Elastic Group of below 30%
2. A notification is sent to the operator email defined in the template, reporting the status, and the Scaling Policy is triggered to scale down the Elastic Group
3. A Zend Server instance in the Elastic Group is stopped

Note:

Instances can also be manually removed from the server deployment using the AWS Management Console, though this not recommended.

4. During shutdown of the Zend Server instance, it is removed from the cluster while migrating sessions in Session Clustering
5. The Zend Server instance is removed from the Elastic Load Balancer

Get acquainted with basic AWS concepts:

Term	Description
Amazon Machine Image (AMI)	A template that contains a software configuration (for example, an operating system, an application server, and applications). From an AMI, you launch instances, which are copies of the AMI running as virtual servers in the cloud. You can launch multiple instances of an AMI, as shown in the following figure.
Instance	Amazon EC2 Instances are virtual servers that can run applications that are created from an AMI and after selecting an appropriate instance type. Instance types comprise varying combinations of CPU, memory, storage, and networking capacity and give you the flexibility to choose the appropriate mix of resources for your applications. Each instance type includes one or more instance sizes, allowing you to scale your resources to the requirements of your target workload.
CloudFormation	AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion.
CloudFormation Template	A CloudFormation template includes pre-configured software instances for quick deployment on EC2. Once deployed, templates can be configured, removed, or re-deployed using the AWS Management Console, through the AWS CloudFormation command line tools or via the AWS CloudFormation APIs. You can deploy and update a template and its associated collection of resources (called a stack) via the AWS Management Console, CloudFormation command line tools or APIs.
AWS Management Console	The AWS Management Console provides a simple web interface for using Amazon Web Services. Log in using your AWS account name and password.
