Leveraging AWS infrastructure services for scalability

In this section, we will shift our focus to strategies you can use to leverage the AWS cloud infrastructure to scale your applications.

Using AWS CloudFront to distribute content

Try to offload as much content as possible to the AWS CloudFront CDN service for distribution to Amazon edge locations. CloudFront can be used to deliver your entire site including static, dynamic, streaming, and interactive content. It can also work with a non-AWS origin server that stores your original content.
