You might be wondering, what exactly is load balancing?

Think of it as a traffic cop for your website. Just like a traffic cop directs cars during peak hours to avoid congestion, load balancing does the same for your WordPress site.

When your site starts getting more visitors, it means more work for your backend servers, especially during peak traffic times. Load balancing distributes network traffic across multiple servers. This way, no single server gets overwhelmed.

Load balancer sits in front of your web server and distribute incoming website traffic across all available servers. This distribution means that all the heavy lifting doesn’t fall on just one server.

It’s like giving your website a bunch of helpers so it can serve more people at the same time without slowing down or crashing.

Now, for those who run wordpress sites, implementing load balancing might sound like a tech nightmare. But, here’s the good news – it’s not as complicated as it sounds. read further to understand how.

• Hardware-based Load Balancing: Hardware load balancers employ dedicated hardware devices to distribute traffic among a set of backend servers. These devices are built specifically for the task, offering robust and reliable traffic distribution.

• Software-based Load Balancing: This method utilizes software that’s installed on a server, turning it into a traffic director. It’s a more flexible and cost-effective solution, perfect for adjusting to the changing demands of your website traffic.

How to Load Balance WordPress

Hey there! Ready to give your wordpress sites the power to handle loads of visitors without breaking a sweat?

You’re in the right spot.

Let’s walk through the steps together, making sure your site can welcome everyone with open arms, no matter how crowded it gets.

Method #1 – Server Side Load Balancing

Here’s how you get started:

Set Up Your Servers: Deploy multiple web servers to host your WordPress site. Each separate server should have identical configurations.

They should all have the same content, themes, and plugins to provide a consistent experience for your users. Ensure that each server has PHP, MySQL (or another database server), and WordPress installed.

Database Configuration: Kick things off by setting up a single, powerful database server or a robust database cluster. This is where all your site’s data lives. Adjust the `wp-config.php` file on each of your web servers to point them to this database powerhouse, ensuring they all sing from the same song sheet.

Unified File Storage: Have you ever visited a friend and noticed how all their books, photos, and music are neatly organized in one place?

That’s the vibe we’re going for with your WordPress files, themes, and media uploads. Store them in a shared file system or network-attached storage (NAS) so every server can access the same content, making your site consistent and reliable for every visitor.

Picking the Perfect Load Balancer: It’s time to choose your perfect load balancer.

Are you going with a sturdy hardware load balancer, or a versatile software option like Nginx or HAProxy, or maybe a cloud-based hero like AWS Elastic Load Balancer or Azure Load Balancer?

If you have CPanel, there’s bad news you can’t load the balance backend server or WordPress instances as it’s still under progress as you can see here.

But if You are on AWS, then you can use an Elastic load balancer, Elastic Load Balancing offers a variety of load balancers to choose from, including Application Load Balancers, Network Load Balancers, Gateway Load Balancers, and Classic Load Balancers. Pick the one that fits your requirements best. For further details, refer to the Product comparisons section.

Tuning the Load Balancer: This is where the magic happens. Configure your chosen load balancer, which distributes network traffic across your backend servers.

Sessions Persistence: If your site likes to remember user sessions, set up sticky sessions in your load balancer. This makes sure users keep talking to the same server, ensuring a smooth and friendly experience.

SSL Termination(if you’re using HTTPS): Secure sites are happy sites. If you’re using HTTPS, set up SSL termination at the load balancer, where the SSL decryption party happens before traffic hits your servers in plain HTTP.

Directing Domain Traffic: Point your domain’s DNS records to the load balancer’s IP address. This is like telling the Internet where your site’s new digital home is.

Testing 1, 2, 3: Before you go live, run thorough tests to make sure traffic flows smoothly and all servers are playing nicely with each other.

Method #2 – Load Balance Using Cloudflare

You don’t have to act like a technical geek for this method; all it takes is to toggle a button. Interesting, isn’t it?

First, configure your domain with cloudflare and proxies your domain in Cloudflare DNS to make it work.
