Guide to ELB-Integrated AWS Services
What is ELB-Integrated AWS Services?
ELB or Elastic Load Balancing is an AWS service that automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. It plays a crucial role in making web-based applications scalable and highly available. Integration of ELB with other AWS services amplifies its benefits and functionality.
Why is it important?
This implementation is critical as it helps in scaling your applications and providing a seamless experience to the end-user by ensuring zero downtime, even under heavy traffic. It also ties up with the concept of automatic scaling which is a core principle in the AWS environment.
How does it work?
ELB accepts incoming traffic from clients and routes requests to its registered targets within the VPC (Virtual Private Cloud) based on the routing algorithm. When integrated with other AWS services, ELB monitors the health of registered targets and routes traffic only to the healthy ones. In case of any detected unhealthy targets, Auto Scaling feature of AWS can be used to launch more instances to handle the load.
Exam Tips: Answering Questions on ELB-Integrated AWS Services
Understanding concept is important but being able to practically apply your knowledge is crucial for exams:
1. Understand the ELB types: AWS offers three types of load balancers - Classic Load Balancer, Network Load Balancer, and Application Load Balancer. Knowing their unique features will assist in choosing the best for a given scenario.
2. Remember Interactions with other AWS services: An effective solution design depends on how well ELB works with other AWS services. Be familiar with these dependencies.
3. Know the routing algorithm: ELB uses a round-robin algorithm for Classic Load Balancer and uses a flow hash algorithm for the Application and Network Load Balancers.
4. Keep Security in mind: ELB can be integrated with AWS WAF, Amazon CloudFront and it can use SSL/TLS for secure connection.
Studying and understanding these points will equip you with enough knowledge to correctly answer exam questions on the topic of ELB-Integrated AWS Services.

ELB-Integrated AWS Services practice test
Elastic Load Balancing is highly integrated with various AWS services, offering several benefits for better performance and security of your applications. Some popular integrated services include: 1. Amazon Route 53: It allows you to map domain names to your load balancers, easily directing customers to your applications. 2. AWS Certificate Manager (ACM): You can use ACM with your ELB to deploy SSL/TLS certificates for secure and encrypted connections. 3. AWS Web Application Firewall (WAF): It integrates with your ELB to help protect your applications against common web attacks. 4. AWS Auto Scaling: It works cohesively with ELB to automatically scale the number of instances based on the traffic load, ensuring consistent performance under fluctuating workloads. By leveraging these integrated services, you can achieve better performance, security, and scalability for your applications.
