Overview of a CDN for Magento 2

Magento CDN speeds your online store. It sends content from servers that are close to your customers.

CDN for Magento 2 reduces load times and smooths the shopping experience. It's a content delivery network. It keeps copies of your store's media files and static content on servers worldwide. It sends content from the nearest server to your visitor. This makes your site load faster.

• It lowers the load on your main hosting server.

• CDN can handle big traffic spikes to keep your store running without issues.

• It reduces server load by using strong caching for your site’s uptime.

• Many CDNs, such as Cloudflare, provide DDoS protection and bot mitigation.

• Check your CDN’s security offerings to meet Magento’s PCI compliance needs.

• It speeds up page loads through content delivery. This often includes image compression, depending on the provider.

Why Use a CDN with Magento 2?

A CDN works for Magento 2 stores with customers in many places. The site may load with delays if your main server is far from some users, such as a US store serving Australia. This can affect user experience and cause more visitors to leave.

Magento 2 sites often face sudden traffic spikes. A single server may struggle to manage these loads with efficiency. The server may overload, slow down, or stop working without a CDN. A content delivery network directs user requests to nearby proxy servers. This lowers the load on the main server.

A CDN speeds up content delivery. It balances the server load and keeps site performance steady. This happens no matter where customers are. It speeds up the site, creating a better user experience. It also maintains efficient operations during busy times.

How a CDN works with Magento 2

1. User Request Starts the Process

When customers visit your Magento store, their browser asks for the site's files. This includes:

• Images

• Styles

• Scripts

• The page itself.

Without a CDN, this request would travel to your main server. It might be far away, causing delays.

2. CDN Handles the Request

With a CDN set up, the CDN’s network catches the request. The CDN directs the request to the nearest server location, a Point of Presence (PoP). For the Sydney customer, that might be a server in Australia, not the distant main server. This cuts down the time it takes to get the files.

3. Checking the Cache

The server in Australia checks if the CDN has already saved the requested files. Magento 2 stores often contain many static files. These include product images and styles. Caching these files is very useful. If the files are there (a cache hit), the CDN sends them straight to the customer. This skips the main server and makes the site load much faster.

4. Getting Files from the Main Server

If the CDN does not have the files (a cache miss), it will ask your main Magento server for them. This can happen if the page changes or someone requests a new image for the first time. The main server then returns the files to the CDN, which stores them for next time.

5. Delivering Content

Once the CDN has the files, it sends them to the customer’s browser. This means the Sydney visitor receives images, scripts, and styles without delay. The CDN delivers content fast. Depending on the provider, it often compresses files and uses advanced web tech.

6. Keeping the Cache Updated

Do not forget to clear the CDN cache when you add new product images to your Magento store. You can do this by hand or establish automated rules. This helps remove old files and caches the new ones.

Providers like Fastly work with Magento’s Varnish. This helps with smooth updates. Customers always see the latest content.

7 Steps to Configure a CDN in Magento 2

Step 1: Log in to Your Magento Admin

  1. Base URL for Static View Files: This is where the CDN stores your CSS, JavaScript, and other static content.

  2. Base URL for User Media Files: Add the URL that points to the images and media uploaded by users.

Note: If you do not have a CDN link for one of these, leave it blank so you can use your store’s default URLs.

Step 5: Add Secure CDN Links

• Scroll down and expand the Base URLs (Secure) section.

• Add the same CDN links, but use the HTTPS versions:

Step 6: Save Your Settings
