Description: A group instance in the context of Elastic Load Balancer (ELB) refers to a collection of virtual machines or servers that are part of a specific set of resources used to efficiently distribute workload. These instances are fundamental to ensuring high availability and scalability of cloud applications. By being organized into groups, instances can be managed collectively, allowing system administrators to make configurations and adjustments more easily. Each instance within a group can receive network traffic evenly, helping to prevent overload on a single server and improving overall system performance. Additionally, group instances can be configured to automatically scale based on demand, meaning that instances can be added or removed as needed, optimizing resource usage and reducing costs. In summary, group instances are key components in load balancing architecture, enabling organizations to efficiently handle traffic and maintain service continuity.
