AWS Certified Cloud Practitioner (CLF-C01)- Elastic Load Balancers (ELB)

The video tutorial provides an in-depth look at the Elastic Load Balancer service on AWS, covering its types: Classic, Application, and Network Load Balancers. It explains how these load balancers manage incoming traffic, ensure high availability, and distribute traffic across healthy instances. The tutorial highlights the features and use cases of each load balancer type, including path-based and host-based routing for Application Load Balancers and static IP support for Network Load Balancers. Monitoring and logging capabilities are also discussed, emphasizing the importance of using AWS tools like CloudWatch and CloudTrail.
