Advantages Of Network Load Balancer

Using a Network Load Balancer instead of a Classic Load Balancer has the following benefits:

• Capable of managing erratic workloads and expanding to millions of requests per second.
• Allow the load balancer to use static IP addresses. One Elastic IP address can also be assigned to each subnet when the load balancer is activated.
• Support for IP address-based target registration, including support for targets outside the load balancer’s virtual private cloud.
• Ability to route requests to several apps using a single EC2 server. Multiple ports can be used to register each instance or IP address with the same target group.
• 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 Amazon CloudWatch metrics are reported at the target group level, and health checks are specified at that level. By joining a target group to an auto-scaling group, you may dynamically scale each service according to demand.

Gateway Load Balancer (GLB)

With the help of gateway load balancers, you can install, grow, and control virtual appliances including intrusion detection and prevention systems, firewalls, and deep packet inspection machines. It divides traffic while growing your virtual appliances with demand, utilizing a transparent network gateway—a single point of entrance and departure for all traffic.

A Gateway Load Balancer functions at the network layer, the third tier of the Open Systems Interconnection (OSI) paradigm. The listener rule specifies the target group to which traffic is sent after it scans all ports for IP packets. With the use of 3-tuples (for non-TCP/UDP flows) or 5-tuples (for TCP/UDP flows), it keeps flows sticky to a particular target appliance.

Classic Load Balancer (CLB)

In AWS, a CLB is the most traditional kind of load balancer. It can manage transport layer and application-layer HTTP, HTTPS, and TCP traffic. Basic functions including cross-zone load balancing, sticky sessions, and health checks are supported. The more sophisticated capabilities of the other kinds of load balancers, such as web sockets, content-based routing, and HTTP header modification, are not supported by it. Simple load-balancing applications that don’t need the functionalities of other load-balancer types can be handled by a CLB. Incoming application traffic is split up across many EC2 instances in various Availability Zones by a load balancer. Your applications’ fault tolerance will rise as a result. Traffic is only sent to healthy instances when Elastic Load Balancing identifies unhealthy ones.

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.
