Advantages Of Using Application Load Balancer
There are several advantages to using an Application Load Balancer over a Classic Load Balancer.
- There is support for path conditions. Rules that route requests based on the URL in the request can be set up for your listener. By doing this, you may divide up your application into smaller services and use the content of the URL to determine which service should get requests.
- Provides support for host conditions. Rules that route requests depending on the host field in the HTTP header may be set up for your listener. This lets you use a single load balancer to redirect requests to many domains.
- Allow routing depending on request information, including source IP addresses, query parameters, HTTP header conditions, and methods.
- Ability to route requests to several apps using a single EC2 server. An instance or IP address can be registered on several ports with various target groups.
- Allow requests to be redirected from one URL to another.
- Allowing a customized HTTP response to be returned.
- Enables targets outside of the load balancer’s Amazon VPC to be registered by IP address.
- Allow Lambda functions to be registered as targets.
- Allow your load balancer to verify users of your apps using their social or business identities before rerouting queries.
- Support for containerized apps. When scheduling a job, Amazon Elastic Container Service (Amazon ECS) can choose an idle port and use it to register the task with a target group. You can use your clusters more effectively as a result.
- Support for tracking each service’s health separately, as many CloudWatch metrics are reported at the target group level, and health checks are specified at that level. By joining a target group to an AWS auto-scaling group, you may dynamically scale each service according to demand.
- Access logs are compressed files that include extra information.
- Increased load balancer performance.
Network Load Balancer (NLB)
At the transport layer (Layer 4), NLBs are made to manage TCP, UDP, and TLS traffic. It can process millions of requests per second at a high throughput and low latency. Long-lasting TCP connections, source IP preservation, elastic IP addresses, and static IP addresses are among the capabilities it also provides. Network-intensive applications like gaming, streaming, and voice-over IP (VoIP) may be load-balanced with an NLB.
What Are AWS Load Balancer Types ?
Managing and allocating incoming network traffic is a critical component in the dynamic realm of cloud computing that helps to guarantee high availability and dependability for online applications. Load balancers from Amazon Web Services (AWS) offer a reliable solution. It’s critical to comprehend load balancers if you’re new to using AWS. The practice of load balancing divides incoming traffic among several servers or applications to maximize scalability, availability, and performance. AWS provides many load balancer types to meet various circumstances and demands. We will explore the idea of AWS load balancers in this post, going over terms, detailed procedures, diagrams, and examples to help you understand the basics.
