I created an SSL certificate last night for use with an API (Tomcat, Spring Boot) on AWS Elastic Beanstalk using instructions provided by Amazon Certificate Manager.
When creating the cert, I entered the URL of my static site that calls the API, which is hosted by GoDaddy. ACM sent an email to my URL which I opened and approve and I now see the cert as issued, by Amazon, in my certs. I am also able to select it when I configure HTTPS for my EB load balancer. I am not able to export this cert though as it isn't private.
My question is, how is domain name used? I think I'm a little confused about how to use SSL on both my API and my static site AS WELL as the small bit of static content I'll host out of Tomcat.
Thanks.
ACM certs can only be used with AWS services - Cloudfront (if the cert is issued in us-east-1) and regionally on the classic load balancer and application load balancer.
You cannot export the cert for use in other products, so if you wanted to have Tomcat handle SSL you would need to get either a commercial cert or use something like Let's Encrypt.
If you have multiple host names you want to protect, you have different options.
You can get one cert per hostname if they are running on completely separate infrastructure; you can also have multiple host names in a single cert - even if there are multiple domains; and finally you can get a wildcard cert.

If I create a new AWS Application Load Balancer (ALB) using HTTP, then AWS will create a load balancer with a randomly assigned domain name. Why can't AWS do the same thing when I create a new ALB using HTTPS? Instead, when creating a new ALB using HTTPS, AWS requires me to provide a custom domain name and custom certs.
The reason is that for valid public SSL certificate you require your own domain that you control. You can't register the certificate for the default domain provided by AWS for ALB because this is not your domain.
Having SSL certs is a lot of work, including managing its registration and renewals. I guess AWS does not want to do that, though they provide SSL for CloudFront AWS-provided default domains.
great question...
With many other aws tools like Amplify you will get a working https address on random aws domain, without the need to upload a certificate to a custom domain.
here They force me to use a certificate, which forces me to use aa custom domain and not the random autogenerated aws https address.
As per the docs - https://docs.aws.amazon.com/elasticloadbalancing/latest/application/create-https-listener.html
To use an HTTPS listener, you must deploy at least one SSL/TLS server
certificate on your load balancer. The load balancer uses a server
certificate to terminate the front-end connection and then decrypt
requests from clients before sending them to the targets.
The load balancer requires X.509 certificates (SSL/TLS server
certificates). Certificates are a digital form of identification
issued by a certificate authority (CA). A certificate contains
identification information, a validity period, a public key, a serial
number, and the digital signature of the issuer.
When you create a certificate for use with your load balancer, you must specify a domain name.
You could use Amazon's ACM to provision your certs. You will only be charged for the application as mentioned in the docs below - https://docs.aws.amazon.com/acm/latest/userguide/acm-billing.html
I've deployed my Django app on AWS Elastic Beanstalk Linux instance. I've used Route 53 to point it to a custom domain from GoDaddy.
Now I want to use SSL for my website.
I don't want to use Load Balancers for SSL since I'm using only 1 instance and it's costly to pay $18/month.
So what I did is using Let's Encrypt SSL by adding 00_apache_ssl.config file in my .ebextensions folder.
I've followed this tutorial to use the SSL. My SSL is working perfectly for Elastic Beanstalk URL. But the problem is it's not working for my custom domain.
My EB Url is showing secure connection while it's custom domain is showing Insecure connection.
What I'm lacking of? Do I need to do some changes in Route 53 Record sets as well?
Thank you.
Edit 1: My custom domain is showing the Let's encrypt certificate as Invalid Certificate.
According to your tutorial, you have got an SSL certificate for your elasticbeanstalk domain, not your custom domain.
If you want to access your website via your custom domain with https (for e.g https://my-cust-doamin.com), you have to get a certificate for your domain.
You can obtain SSL certificate from any provider who sells SSL certificates.
Note: You can also get a wildcard certificate(*.my-cust-domain.com), which could be used with any of your sub domains.

I have an ELB instance installed on my AWS account (http://editoradbosco.us-east-2.elasticbeanstalk.com), and it is working normally. My domain is installed on Hostgator (https://centrodombosco.org), and on this, I have a CNAME that points to my AWS endpoint (http://editora.centrodombosco.org).
However, I need to use an HTTPS (SSL) protocol. How can I proceed? I have an SSL contracted on Hostgator for this subdomain, but Hostgator has informed me that I need to make adjustments to AWS so that it works, but I do not know how to proceed.
How can I make this work?
I tried to create an SSL by Certificate Manager on AWS, appointing the CNAMES on my DNS Panel on Hostgator. But it fails. I guess its not possible to use AWS Certificates outside AWS Domains.
There are two ways you can do this.
Since you already have an SSL from Host Gator, you can import that certificate to AWS Certificate Manager (instructions here). Once you import a certificate it is immediately considered validated and you can immediately proceed to configure your EB environments Load Balancer to terminate HTTPS as described here.
Alternatively, if you’d like to use Amazon Certificate Manager but for some reason the DNS validation isn’t working, or its not possible for you to validate ownership of the domain using the DNS method, Amazon Certificate Manager also offers you the option to use email to validate your ownership of the domain, as described here. Once your ownership of the domain is validated you can then proceed to configure your EB environments Load Balancer to terminate HTTPS as described here.
As a side note, you may wish to consider using Route53 to handle DNS for your domain. Route53 is tightly integrated with AWS services such as ACM and, as is the case with ACM, services requiring custom DNS entries will often offer to make the correct DNS entries directly in to your Route53 hosted zone on your behalf.
I am not into SSL at all, so bear with me please. I have no idea how to start to actually solve my problem.
Current situation:
1x Webserver with Webspace for a Website and it includes a Domain Administration, also to order SSL Certificates etc.
1x Different Webserver at Amazon Web Services with a PHP-based Software on it with Login etc.
A Subdomain that I created in the Domain Administration is pointing via DNS to the IP of the AWS.
What I need:
I want an https Connection (SSL) for the Subdomain that is pointing to the AWS so that the connection/login is secure.
My question is what I have to do on the side where I have the Domain Administration and after that what I have to do on the side of the AWS.
Thank you so much!
You have several options in hand,
If you already have a SSL certificate purchased, you can include it inside the webserver (e.g; configure apache for SSL).
If you plan to use free SSL certificates from Amazon, you can use one of the following options after creating a SSL certificate in AWS Certificate Manager.
Create a AWS CloudFront Distribution and attach the SSL certificate there while configuring an origin to forward traffic to the specific web server. However, you need to create the SSL certificate in North Virginia region and there won't be any upfront costs for CloudFront). CloudFront acts as a proxy and you can explicitly instruct to cache the static content reducing the load for web server and improving the performance.
The other option is to create a Application Load Balancer (ALB) and attach the SSL certificate there ( Create the SSL certificate in the same region) while forwarding traffic to the web server. However, this will add a monthly reoccurring costs for the ALB.
All you need to do is, on AWS ACM (AWS Certificate Manager) procure a certificate for your subdomain and use AWS ELB to use the certificate and point to the AWS webserver.
After this use the ELB IP in the DNS settings.
There are other options too like procuring the subdomain certificate and installing it on the webserver on AWS.
My iOS software platform runs on AWS Elastic Beanstalk and has a URL we'll call "something.elasticbeanstalk.com". I have a website we'll call "website.com" I purchased and operate the DNS records for through Namecheap. I need to make the URL my iOS client apps use to connect to the server HTTPS since Apple is requiring this soon due to App Transport Security.
WHAT I THINK I'M SUPPOSED TO DO
What I think I'm supposed to do is, create an SSL certificate for "website.com" and apply that SSL certificate to the AWS EB load balancer. Then I need to create a subdomain for "website.com" that redirects traffic to "something.elasticbeanstalk.com". Client apps connect to the subdomain of "website.com" which is now HTTPS and redirects to "something.elsastic.beanstalk.com". Is that correct?
WHAT I'VE DONE SO FAR
So far, I created a SSL certificate for "website.com" using AWS Certificate Manager. For this I had to verify my email address associated with "website.com". I then applied that SSL certificate to my environment's load balancer int the AWS Management Console. After that, I went into Namecheap and followed this guide in the 'Domain Name & AWS 53 Management' section to do it.
I read in this article that I needed to create an alias and/or set up Nameservers in AWS Route53. I tried doing that but don't know what I'm doing and it seems to conflict with the Medium article I linked above that I followed telling me to change the CNAME record for the URL and the Redirect URL record for "website.com".
QUESTION
What do I do from here?
SITUATION
-I have a Parse Server on Elastic Beanstalk with URL “something.elasticbeanstalk.com”
-I have a domain with Namecheap called “website.com”
WHAT I NEEDED
I needed to make my client app connect to an HTTPS address since Apple is requiring it shortly with App Transport Security. Since I couldn’t get an SSL certificate using AWS certificate manager for “something.elasticbeanstalk.com”, I created one for “website.com”. I then needed to have my client app connect to the HTTPS “website.com” which would forward it over to “something.elasticbeanstalk.com”. This satisfied the HTTPS requirements of Apple.
HOW TO DO IT
Make an SSL certificate for “website.com” using AWS Certificate Manager. You will need to confirm the domain via a confirmation email to the administrator for it.
Apple the SSL certificate for “website.com” to the AWS EB Load Balancer. Go to your AWS EB Console, click "configuration", click "Load Balancing" under the "Network Tier" category. Now under the first category which is "Load Balancer", select the SSL record you made and apply it in the "SSL certificate ID" section.
Set a CNAME record for “website.com” with a host of whatever subdomain of “website.com” you want. I chose “data” as my host value and subdomain (so my subdomain is “data.website.com”). Set the value of the CNAME record to “something.elasticbeanstalk.com”. Wait for it to propagate. It’s usually pretty fast but not always.
(I’m unsure if this particular step is proper but it worked for me) Set the serverURL of Parse-Server to “https://something.elasticbeanstalk.com” and the publicServerURL to “https://data.something.com”
In the Parse “initializeWithConfiguration” method in your client app that enables the app to connect to the server, change the server URL to “https://data.something.com/parse”. NOTE: include the “/parse” which is the MOUNT PATH of the parse-server. This value MAY BE DIFFERENT for you depending on how you set it but I set it to “/parse” since that’s what I saw in the Parse-Server docs.
NOTES
-I deleted all Route53 records since they are irrelevant here since “something.com” DNS services are controlled by Namecheap.
-A Redirect URL record in Namecheap is unnecessary
