                                                            Lab 11:Load Balancer




What is Load Balancer ? Why we use it?

It Automatically distribute incoming traffic across mutiple targets such as EC2 instances containers,IP addresses,and lambda functions.It can handle have varying load of your applications traffic in a single availability zone or Cross multiple availability zones.

There are Three types of load Balancers are there:
1.Classic load balancer--------------->It provides basic loading balancing across multiple EC2 instances and operates at both the request level and connection level.It is intended for applications that were built within the EC2 -classic network.

2.Application Load Balancer----------------->it provides advanced request routing targeted at delivery of modern application architecture,including ,microservices and container-based applications.

3.Networking load Balancer ------------------>It is capable of hadling millions of request per second while
maintaining ultra-low latencies.It is optimized to handle sudden and volatile traffic patterns while using a single static ip address per availability Zone.

Some key words:

High availability
Target groups
Health check
