AWS Elastic Load Balancing (ELB) vs Eureka: What are the differences?

Developers describe AWS Elastic Load Balancing (ELB) as "Automatically distribute your incoming application traffic across multiple Amazon EC2 instances". With Elastic Load Balancing, you can add and remove EC2 instances as your needs change without disrupting the overall flow of information. If one EC2 instance fails, Elastic Load Balancing automatically reroutes the traffic to the remaining running EC2 instances. If the failed EC2 instance is restored, Elastic Load Balancing restores the traffic to that instance. Elastic Load Balancing offers clients a single point of contact, and it can also serve as the first line of defense against attacks on your network. You can offload the work of encryption and decryption to Elastic Load Balancing, so your servers can focus on their main task. On the other hand, Eureka is detailed as "AWS Service registry for resilient mid-tier load balancing and failover". Eureka is a REST (Representational State Transfer) based service that is primarily used in the AWS cloud for locating services for the purpose of load balancing and failover of middle-tier servers.

AWS Elastic Load Balancing (ELB) can be classified as a tool in the "Load Balancer / Reverse Proxy" category, while Eureka is grouped under "Open Source Service Discovery".
