I want to install certificate on Ec2 for domains and subdomains.
I'm running a website "www.example.in" on single EC2 instance which is in public subnet with public IP and also pointing some subdomains like "api.example.in", "dashboard.example.in" and "jenkins.example.in" to the same EC2 instance.
I thought to use ACM certificate to secure my website but ACM certificate can't be use directly on EC2 instance.
If i use third party tools like "let's encrypt". If I install certificate directly on EC2, will it block my subdomains or will impact on my website?
With ACM (Amazon certs)
https://aws.amazon.com/premiumsupport/knowledge-center/configure-acm-certificates-ec2/
Without ACM (bring your own cert)
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-amazon-linux-2.html
No, it will not block your website. "Let's encrypt" works just fine. I have worked with it.
Regarding your subdomains, you can create a wildcard certificate that can provide SSL for example.in and all subdomains (e.g. api.example.in, dashboard.example.in).
Let's Encrypt supports wildcard certs.

So my team just moved my website from another host to Amazon Lighsail (Wordpress) on the previous host it's already secure (HTTPS), my team also already upload my own cert using Certificate Manager but how to connect it to the Lightsail ?
PS : we already ask the support there, but they only give me the documentation how to use load balancer, ignoring that we already said our own cert
my own cert using Certificate Manager but how to connect it to the Lightsail ?
You can't use AWS ACM SSL certificates on instances. They can be only used on load balancers, CloudFront distribution and API Gateway. It does not matter that it is imported cert or not.
To use your own SSL cert, you have to setup your Lightsail instance yourself, without ACM. Usually it is done by using nginx as a reverse-proxy in front of your application and manually configuring it to use your SSL certificate. ACM is not involved in this process. Its fully manual setup on your behalf.
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.
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 parent domain is https & also with www. This certificate is purchased from comodo. I have two other sub-domains which I want to make https too.
Can I get a wildcard SSL from AWS (CouldFront) and use it for those sub domains?
Please let me know.
You cannot get a SSL certificate from AWS Cloud Front. You have to get that from AWS Amazon Certificate Manager (ACM). And yes you can get a wild card from AWS ACM and use that for your subdomains.
When I deploy apps on Google App Engine, they automatically get use of the appspot.com wildcard SSL cert allowing me to have https secure URLs.
Does AWS give you this option, or is installing your own SSL cert the only option?
Amazon only provides free SSL certs through the ACM service, which is currently restricted to CloudFront distributions and Elastic Load Balancers that you have configured with your own custom domain name.
There are other ways to obtain a free SSL cert if you own your own domain name, such as CloudFlare and Let's Encrypt.
