The pattern provides guidance for using AWS Certificate Manager (ACM) to migrate existing Secure Sockets Layer (SSL) certificates from websites that are hosted on on-premises servers or Amazon Elastic Compute Cloud (Amazon EC2) instances on Microsoft Internet Information Services (IIS). The SSL certificates can then be used with Elastic Load Balancing on AWS.

SSL protects your data, affirms your identity, provides better search engine rankings, helps meet Payment Card Industry Data Security Standard (PCI DSS) requirements, and improves customer trust. Developers and IT teams that manage these workloads want their web applications and infrastructure, including the IIS server and Windows Server, to remain compliant with their baseline policies.
