Load balancing in cloud computing refers to distributing workloads across multiple computing resources to improve performance, minimize downtime, and ensure resource utilization.
Energy efficiency in cloud computing is concerned with reducing the energy consumption of these resources to minimize the environmental impact and reduce operational costs. Energy efficient load balancing techniques in cloud computing discuss methods and algorithms used to distribute workloads and resources to minimize energy consumption while maintaining performance and availability.
Load balancing is a critical component of cloud computing, as it helps to ensure that resources are utilized effectively and efficiently, avoiding resource contention and optimizing performance. However, traditional load-balancing algorithms can consume a significant amount of energy and negatively impact the overall energy efficiency of cloud computing environments.
