Running an Elastic LAMP Stack on AWS

This article demonstrates a streamlined approach to deploying and managing a highly scalable LAMP stack on AWS using Zend Server. Forget complex configurations; this method leverages a pre-built AWS CloudFormation template for rapid deployment.

Note: "Elastic" here refers to scalability, not Elasticsearch.

The CloudFormation template automates the setup of a complete LAMP stack: Zend Server's optimized PHP environment (including Z-Ray), a MySQL database (RDS), an elastic load balancer, an auto-scaling group of Zend Server instances, and robust security configurations. This solution is ideal for both migrating existing applications and establishing new cloud-based production environments.

Key Advantages:

• Simplified Deployment: A pre-configured CloudFormation template eliminates manual infrastructure setup.
• Elastic Scalability: The auto-scaling group dynamically adjusts the number of Zend Server instances based on demand.
• Centralized Management: Manage Zend Server, PHP, and the MySQL database through intuitive consoles.
• Easy Application Deployment: Deploy applications easily using the provided WordPress sample application and the Deploy Application wizard.
• Robust Monitoring: Zend Server's advanced monitoring tools provide real-time insights and alerts.

Core Concepts:

Zend Server provides a comprehensive platform for PHP application development, deployment, and monitoring. AWS CloudFormation streamlines infrastructure provisioning, automating the creation and management of resources like EC2 instances, load balancers, and auto-scaling groups.

Prerequisites: An active AWS account and approximately 30 minutes.

Step 1: Launching the Stack

1. Access the AWS Marketplace and search for "Zend Server."
2. Select the "PHP 5.6 – Zend Server Professional Edition (Ubuntu)" AMI (or a suitable alternative). Note that only Professional and Enterprise editions support clustering.
3. Choose the "Zend Server Cluster" delivery method.
4. Utilize the CloudFormation Designer to review the template. While customization is possible, proceed with caution.
5. Click "Create Stack" to launch the deployment wizard.
6. Provide a stack name, configure network settings (VPC and subnets), and specify access credentials (EC2 key pair, Zend Server UI password, database credentials, and optional email notifications).
7. Select instance types for Zend Server nodes and the database (defaults are sufficient for moderate loads). Define the minimum and maximum sizes for the auto-scaling group.
8. Review the stack configuration and acknowledge the creation of a new IAM profile.
9. Click "Create" to initiate the deployment. Monitor the stack's progress in the CloudFormation console.

Step 2: Managing the Stack

Manage the Zend Server nodes via the EC2 console. The load balancer is also managed through the EC2 console. The MySQL database is managed via the RDS console. Access Zend Server using the URL from the CloudFormation Outputs tab and the password you set during deployment. Configure PHP extensions and directives through the Zend Server UI.

Step 3: Deploying an Application

Deploy the sample WordPress application using the Zend Server UI's Deploy Application wizard. Provide the necessary application details and database credentials.

Step 4: Monitoring the Stack

Utilize Zend Server's monitoring features to analyze logs and track application performance. Set alerts for critical events.

Conclusion:

Zend Server on AWS offers a significantly simplified approach to managing elastic LAMP stacks, eliminating the complexities often associated with cloud-based PHP deployments. The automated deployment and robust monitoring capabilities make it a compelling solution for production environments.
