Apache

As explained in Amazon Web Services in Action, Third Edition: An in-depth guide to AWS

Apache is an open-source web server software project that serves web content and handles HTTP requests.

Apache is an open-source web server that serves web pages and handles HTTP requests. In a WordPress deployment, it runs on Linux virtual machines alongside PHP and WordPress. section 2.0 section 2.1

A highly available setup installs Apache on at least two EC2 instances. An Application Load Balancer distributes requests between healthy instances and stops routing traffic to a failed one. section 2.1

The surrounding infrastructure assigns each component a distinct role:

• Apache serves the WordPress application from the web servers. section 2.0
• The Application Load Balancer distributes HTTP and HTTPS traffic across the Apache servers. section 2.1
• EFS provides shared storage for application files and user uploads accessible by each server. section 2.1
• Security groups restrict incoming and outgoing traffic, including HTTP access to the load balancer. section 2.1

Figure 2.1 The company’s blogging infrastructure consists of two load-balanced web servers running WordPress, a network filesystem, and a MySQL database server.

Shows Apache-based WordPress servers behind a load balancer, with shared storage and a MySQL database. section 2.1

Examples

Uses two Apache web servers running WordPress behind an Application Load Balancer with shared EFS storage.

What it assumes

Uses WordPress, PHP, MySQL, and web-server concepts while identifying their roles in the application stack.

What you can do after

Operate Apache as a WordPress web server on EC2 and place it behind a health-checked load balancer.

How it connects
