Elastic Load Balancer (ELB) in Amazon Web Services (AWS) does support SSL termination and offloading. With SSL termination, the ELB handles the computationally intensive process of decrypting SSL/TLS-encrypted traffic, relieving the backend servers from this task. This process, known as SSL offloading, helps to increase the efficiency of your backend servers and reduces their CPU utilization, thereby enhancing the overall performance of your applications. You can easily manage and deploy SSL/TLS certificates via AWS Certificate Manager and associate them with your ELB. It's also worth noting that Application Load Balancers and Classic Load Balancers support SSL termination and offloading.
