What is a Certificate Chain? Certificate chain (or Chain of Trust) is made up of a list of certificates that start from a server’s certificate and terminate with the root certificate. If your server’s certificate is to be trusted, its signature has to be traceable back to its root CA

What is a certificate chain?
In order to associate the identity and the public key, a chain of certificates is used. The certificate chain is also called the certification path or chain of trust. What are Certificate Chains? The issuer of each certificate (except the last one) matches the subject of the next certificate in the list.
How do I enable SSL/TLS on AWS?
Once the certificate is created, AWS Certificate Manager takes care of deploying certificates to help you enable SSL/TLS for your website or application.

When a browser downloads your website's SSL certificate upon arriving at your homepage, it begins chaining that certificate back to its root. It will begin by following the chain to the intermediate that has been installed, from there it continues to tracing backwards until it arrives at a trusted root certificate.
How do SSL certificates work?
An SSL certificate is a file installed on a website's origin server. It's simply a data file containing the public key and the identity of the website owner, along with other information. Without an SSL certificate, a website's traffic can't be encrypted with TLS.
Is SSL same as TLS?
Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL.
