Load balancing

Citrix Cloud What is load balancing? A load balancer is a device that distributes network or application traffic across a cluster of servers. Load balancing improves responsiveness and increases availability of applications.

Load balancing

Creating a Load Balancer Load Balancing Concepts All of the containers that are launched in a single task definition are always placed on the same container instance. For Classic Load Balancers, you may choose to put multiple containers in the same task definition behind the same load balancer by defining multiple host ports in the service definition and adding those listener ports to the load balancer.

Load balancing

For example, if a task definition consists of Elasticsearch using port on the container Load balancing, with Logstash and Kibana using port on the container instance, the same load balancer can route traffic to Elasticsearch and Kibana through two listeners.

Important We do not recommend connecting multiple services to the same Classic Load Balancer. Because entire container instances are registered and deregistered with Classic Load Balancers and not host and port combinationsthis configuration can cause issues if a task from one service stops, causing the entire container instance to be deregistered from the Classic Load Balancer while another task from a different service on the same container instance is still using it.

If you want to connect multiple services to a single load balancer for example, to save costswe recommend using an Application Load Balancer. There is a limit of one load balancer or target group per service. Services with tasks that use the awsvpc network mode for example, those with the Fargate launch type only support Application Load Balancers and Network Load Balancers.

Classic Load Balancers are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance. This is because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.

Container health checks are not supported for tasks that are part of a service that is configured to use a Classic Load Balancer. Your load balancer subnet configuration must include all Availability Zones that your container instances reside in.

After you create a service, the target group ARN or load balancer name, container name, and container port specified in the service definition are immutable. You cannot add, remove, or change the load balancer configuration of an existing service.

If you update the task definition for the service, the container name and container port that were specified when the service was created must remain in the task definition. This process continues until your service reaches the number of desired running tasks.

Note. If you are using a hardware load balancer, the load balancer deployed for connections with the internal network must be configured to load balance only the traffic to servers running the Access Edge service and the A/V Edge service.

Introduction. Load balancing across multiple application instances is a commonly used technique for optimizing resource utilization, maximizing throughput, reducing latency, and ensuring fault-tolerant configurations.

Classic Load Balancer provides basic load balancing across multiple Amazon EC2 instances and operates at both the request level and connection level.

Classic Load Balancer is intended for applications that were built within the EC2-Classic network. Learn more >> Benefits. With built-in load balancing for cloud services and virtual machines, you can create highly available and scalable applications in minutes with Azure Load Balancer.
