What is Load Balancer?
After have a good understanding of Router and Floating IP, you may want to build a more complex system with many VMs, clusters, databases,... to serve your business. Now, you may hear about a new term: Load Balancer. So, what is Load Balancer and what does it do in Vietnix Cloud?
What is Load Balancer?
A Load Balancer in Vietnix Cloud is a virtual network device that distributes incoming network traffic across multiple instances (VMs) to ensure high availability and reliability of your applications. It helps to balance the load on your servers, preventing any single server from becoming overwhelmed with too much traffic.
What does it do in Vietnix Cloud?
When a load balancer is set up, it acts as a single point of contact for clients trying to access your application. The load balancer receives incoming requests and distributes them to the available instances based on predefined rules and algorithms (e.g., round-robin, least connections, etc.). This ensures that no single instance is overloaded with traffic, which can lead to performance degradation or downtime.
In Vietnix Cloud, the Load Balancer also provides features such as health checks to monitor the status of your instances. If an instance becomes unhealthy or unresponsive, the load balancer will automatically stop sending traffic to that instance and redirect it to healthy instances, ensuring continuous availability of your application.
Overall, the Load Balancer in Vietnix Cloud is a crucial component for building scalable and resilient applications, as it helps to distribute traffic efficiently and maintain high availability for your services.
Summary
In summary, a Load Balancer in Vietnix Cloud is a virtual network device that distributes incoming traffic across multiple instances to ensure high availability and reliability of your applications. It acts as a single point of contact for clients, distributes requests based on predefined rules, and provides health checks to monitor the status of your instances. By using a Load Balancer, you can build scalable and resilient applications that can handle varying levels of traffic without performance degradation or downtime.
