AWS Certificate Manager (ACM) simplifies the process of managing SSL/TLS certificates for our AWS-based websites and applications. It provides free SSL/TLS certificates that are automatically provisioned and renewed for use with AWS services. With ACM, we can easily provision, manage, and deploy SSL/TLS certificates for use with AWS services and resources, such as Elastic Load Balancers (ELB), Amazon CloudFront distributions, and Amazon API Gateway APIs. Alternatively, we can also import third-party certificates into the ACM management system.
