Summary
Uploading a SSL certificate in AWS is required when setting up a HTTPS load balancer or a cloudfront bucket with HTTPS support. The certificate format required by AWS is likely to differ a little bit from what an SSL provider will give you. This article explains how to convert your SSL certificate into to the format expected by AWS

1 - What you need
SSL Providers (like GoDaddy) usually provide three things when generating a SSL certificate:
...
- Private Key in pem format
- Public Key Certificate in pem format
- Certificate chain in pem format: this is the bundle provided by your provider
...
2 - Installing the certificate on the ELB

openssl rsa -in somedomain.key -outform PEM -out somedomain.key.pem |
...
That's pretty much it! 
Now upload the content of each file as directed:
- Upload content of somedomain.key.pem to Private Key
- Upload content of somedomain.crt to Public Key Certificate
- Upload content of provider_bundle.crt to Certificate Chain
Example below while setting up a AWS Load Balancer:
3. Import the certificate in AWS Certificate Manager
Open the ACM console at https://console.aws.amazon.com/acm/home.
Either import a new certificate or select the one to renew and choose "Reimport"
When reimporting a renewed certificate all associated resources (ELB, ...) are automatically updated.
