Load Balancers

Load Balancers are essential for scaling your applications, increasing availability, and ensuring reliability. They automatically distribute incoming traffic across a pool of backend Virtual Machines or Containers.

Why Use a Load Balancer?

• High Availability: If one of your servers goes down, the load balancer automatically reroutes traffic to the healthy instances, ensuring your application stays online.
• Scalability: Handle traffic spikes by easily adding more backend servers to the pool without changing your public IP address.
• Performance: Prevent any single server from becoming a bottleneck by distributing the workload evenly.

Creating a Load Balancer

1. Navigate to the Load Balancers section in the left sidebar.
2. Click "Create Load Balancer".
3. Choose Flavor: Choose the flavor of the load balancer.
4. Deploy: Once created, your Load Balancer will be assigned a public IP address.

Health Checks

To ensure traffic is only sent to healthy servers, the Load Balancer performs continuous health checks.

• You can configure the path (e.g., /health), protocol (HTTP/TCP), port, and frequency of these checks.
• If an instance fails a health check consecutively, the Load Balancer stops routing traffic to it until it recovers.
