Description: The Elastic Load Balancer Security Group is a virtual firewall that controls the traffic allowed to and from the load balancer. This security group acts as a protective barrier, allowing administrators to define specific rules that determine what traffic can access the instances behind the load balancer. Key features include the ability to allow or deny traffic based on IP addresses, protocols, and ports, providing granular control over application security. Additionally, security groups are dynamic and can be modified in real-time, allowing organizations to quickly adapt to changing security needs. The relevance of these groups lies in their ability to protect applications from external attacks, ensuring that only legitimate traffic can reach the backend instances. This is especially critical in cloud environments, where scalability and security are fundamental to the performance and integrity of the services offered.
