It stores cached copies of your website's static content, such as images, CSS files, and JavaScript files, in multiple locations around the world.

Enabling Cloud CDN for WordPress involves a few steps:

1. Sign up for a CDN service: There are several CDN providers available, such as Cloudflare, Amazon CloudFront, and Google Cloud CDN. Choose a provider and sign up for an account.
2. Set up your CDN service: Follow the provider's instructions to create a new CDN distribution or zone. This typically involves configuring settings like the origin server (your WordPress site's server), edge locations, and caching rules.
3. Configure CDN integration plugin: Install and activate a CDN integration plugin on your WordPress site. Popular plugins include W3 Total Cache, WP Rocket, and CDN Enabler. These plugins help synchronize your WordPress site with the CDN service and ensure proper caching and content delivery.
4. Update your WordPress site URLs: Some CDN integration plugins require you to update the URLs of your static content to use the CDN URL. This step ensures that your static files are delivered through the CDN network. The plugin usually provides an option to automatically update these URLs.
5. Test and verify CDN functionality: Once everything is set up, visit your website and verify that the static content is being delivered through the CDN. You can use browser developer tools or online tools like Pingdom or GTmetrix to check whether the CDN is working correctly.

Enabling Cloud CDN for WordPress can significantly improve the load time and performance of your site, especially for users located far from your server's location.

What is Cloud Identity and Access Management (IAM) and how to set it up for WordPress?

Cloud Identity and Access Management (IAM) is a service provided by cloud platforms like Google Cloud, Amazon Web Services (AWS), and Microsoft Azure that enables you to manage user access and control permissions to resources within the cloud environment.

To set up IAM for WordPress, you need to follow these general steps:

1. Choose a cloud provider: Decide which cloud platform you want to use. Some popular options include Google Cloud, AWS, and Azure. Each platform has its own IAM system.
2. Create a project or resource: Create a new project or resource on your chosen cloud platform. This project or resource will host your WordPress website.
