AWS Shield vs ExpeditedSSL: What are the differences?

Developers describe AWS Shield as "Managed DDoS Protection". AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards web applications running on AWS. AWS Shield provides always-on detection and automatic inline mitigations that minimize application downtime and latency, so there is no need to engage AWS Support to benefit from DDoS protection. On the other hand, ExpeditedSSL is detailed as "The Fastest, easiest way to add SSL to your Heroku + AWS Apps". Stop pouring through MAN pages and outdated blog posts that don't take into account new requirements.
