A load balancer’s ability to be integrated into application delivery controllers (ADCs) for improved performance and application security is another advantage. Additionally, if a load balancer fails for any reason, it promptly switches the entire workload to a backup server. Let’s discuss some of its additional features and benefits.
What is Load Balancing?
Load Balancing is a process under which all the workload is distributed evenly among different systems, servers as well as computational resources. This technique basically helps distribute the traffic among several servers uniformly to improve the performance as well as the reliability of each application. This further lessens the load on each server and increases server efficiency, which speeds up performance and lowers latency.
The majority of Internet applications cannot run successfully without load balancing. Additionally, by sending client requests to computer nodes that are idle, it lessens the overloading of computational resources.
Load balancers are tools that act as a middleman between client devices and backend servers, allowing them to receive and direct client requests to various servers. Because it guarantees that the apps are active and available for users, businesses generally choose it for the load balancing strategy.
On a daily basis, hundreds and thousands of requests are received by businesses each minute. And if it is a peak season, you may notice a huge rise in traffic. This in turn affects the server performance. Hence, in order to reduce server pressure and maintain high quality media, most businesses started using load balancers.
These devices basically help in tracking every single incoming request and divert the traffic to respective servers depending on various factors. This way load balancing prevents overworking a single server.
Advantages of Using Apache Load Balancing
- Scalable and lessens troubleshooting.
- Lessened Bandwidth Usage.
- Offers quick and easy access to application insights.
- Multiple web server protection.
- Session Persistence.
- Enables port to port routing within a single instance.
- Saves time and quickly deploys with software load balancers.
- Enables the original server to reject suspicious packets before they arrive.
- Routes client requests while maximizing network efficiency.
- Permits request to be sent to the same server from a specific client.
- Improves user experience and focuses on reducing error responses
Apache Load Balancing: How to Use Apache for Load Balancing
- A root user or a user with sudo privileges.
To demonstrate in this article, we use the following domains.
Update System Packages
First, it is always a good idea to update and upgrade all system packages to the latest version. Update all of them by running the following command on all servers.
apt update -y
apt upgrade -y
Once all the packages are updated, restart all servers to apply the changes.
Install Apache Web Server
apt install apache2 -y
systemctl start apache2
systemctl enable apache2
Then verify the status of Apache service using the following command.
systemctl status apache2
You see the Apache status on the following screen.
Configure First Apache Backend Server
First, create a sample HTML file with the following command.
Add the following code.
Apache Web Server1
