Ansible Keepalived HAproxy | The Trifecta

Did you know that we can use Ansible, Keepalived, and HAProxy together to create a highly available and load-balanced infrastructure for web applications?

If we have a web application that needs high availability and load balancing, these three tools can come together for an optimal solution:

• Ansible can automate the installation and configuration of Keepalived and HAProxy on a set of servers.

  

  Here, we have to define Ansible playbooks. Furthermore, it connects to the servers via SSH and executes the tasks defined in the playbooks for consistency across all servers.
• Next, we have to install and configure Keepalived on each server. It monitors the health of the servers with VRRP. Additionally, it keeps track of the master and backup servers. If the master server becomes unresponsive, Keepalived automatically transfers the virtual IP address to a backup server.
• Then, we must install and configure Haproxy on each server as well. It receives incoming network traffic destined for the web application. Furthermore, HAProxy regularly checks the health of the backend servers and directs traffic only to the healthy servers, ensuring efficient resource utilization and high availability.

By combining tAnsible, Keepalived, and HAProxy we can achieve a highly available and load-balanced infrastructure. If a server fails, Keepalived automatically transfers the virtual IP address to a working server, and HAProxy evenly distributes the incoming traffic to the healthy backend servers. This improves fault tolerance, allows for scalability, and ensures that our web application remains accessible and performs optimally.
