Features of AWS Elastic Load Balancer
AWS Elastic Load Balancer offers several features that make it a popular choice for developers and enterprises, including:1. High availability and scalability: ELB automatically distributes incoming traffic to multiple targets, making your web applications more highly available and fault-tolerant. You can also scale your ELB up or down depending on traffic demands.
2. Multiple routing algorithms: ELB offers several routing algorithms, including Round Robin, Least Connections, and IP Hash, to distribute traffic across multiple targets based on various criteria.
3. Integration with other AWS services: ELB can integrate with other AWS services, including EC2, Auto Scaling, Route 53, and S3, to provide a comprehensive solution for your web application needs.
4. Security: ELB supports SSL/TLS encryption and provides a secure connection between clients and targets, helping protect your data from unauthorized access.
5. AWS Shield: AWS Shield provides protection against Distributed Denial of Service (DDoS) attacks for your ELB, making it a more secure and reliable service.
Types of AWS Elastic Load Balancer
AWS Elastic Load Balancer offers three types of load balancers to support different use cases:1. Application Load Balancer: This is best for HTTP and HTTPS traffic and supports content-based routing, allowing you to route traffic to different targets based on the content of the request.
2. Network Load Balancer: This is best for TCP traffic and supports high performance, ultra-low latency, and static IP addresses.
3. Classic Load Balancer: This is the original load balancer offered by AWS and supports both HTTP and TCP traffic.
Use Cases for AWS Elastic Load Balancer
AWS Elastic Load Balancer is useful in a variety of scenarios, including:1. Scaling web applications: ELB can distribute traffic to multiple EC2 instances, making it easier to handle increasing traffic demands and maintain performance.
2. Improving fault tolerance: ELB can automatically reroute traffic to healthy targets, making your web applications more fault-tolerant and highly available.
3. Reducing latency: ELB can distribute traffic to the closest and healthiest target, reducing latency and improving the user experience.
4. Simplifying architecture: ELB can simplify your web application architecture by eliminating the need for complex networking configurations and reducing the number of single points of failure.
