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 have a VueJS front-end application running on S3 being served as a static website.
I have a NodeJS (behind an nginx reverse proxy, plus a few other services) backend application running on an EC2 instance that the VueJS app talks to (over http currently).
I have a domain successfully pointed at the VueJS app (S3 bucket) with the configured SSL certificates using Route53 / CloudFront / ACM.
However, now the VueJS app will not communicate with the EC2 instance backend as it is still using HTTP which is now not allowed.
So what is the best way to configure this? I can't run certbot on the ec2 instance and generate an SSL certificate for my domain as there are certificates already being used for the S3 bucket.
Should I just create a self-signed certificate?
Can I create another certificate for a subdomain perhaps (api.example.com say) and set up DNS record for that to point to my EC2 instance IP address?
How is this usually done, what is best practice?
So a self-sign cert wont work, it wont pass validation as there is no known CA behind it ( Certificate authority) I mean you can install it but the browser is going to complain..
Im not sure I understand why you cant use certbot.. s3 / ec2 are two seperate services so I'm a bit confused here?
You can use letencrypt to generate a cert for the server and have it installed as well but if you have clusters you may be better served by installing it on the actual ALB, however this does not ensure end-to-end if the cert is not installed on all backend systems, (that would require installing the cert on all systems in the cluster) You requirements will dictate this really.
If you are unable to generate a cert with letsencrypt you can get an SSL from ssls.com and just installed the PEM or CRT on the server / load balancer too though.
Usually you create some subdomain like you said for your api and create a certificate for that subdomain. On AWS in particular, you can use an elastic load balancer and use ACM /Route53 with that for ease of certificate management, but that does carry costs of the load balancer.
Alternative is to just put an API gateway in front of your EC2 instance as a reverse proxy, which will carry some costs, but maybe not as much depending on traffic volume.
I am new on terms of every aspect of SSL certificate.
I have a architecture, where Route53 routes traffic to Load balance.
We are moving to production and we have to implement SSL certification to handle https traffic.
Where should i position the certificate in the architecture?
While searching i sow AWS Certificate Manager.
I am wondering how is it different ?
And when i buy a certificate can i use a single certificate with different account?
(Example: can i have same certificate set up for Staging and multiple production environment)
You can use the ACM to generate certifications for you.
It's totally free, if it's a public certificate, and will automatically renew when it expires.
But some security teams will require you to upload a more advanced certificate than ACM generates for you, in this case, you can buy the certificate and upload it in the ACM service. Keep in mind that it won't renew automatically and when it expires you will have to upload a new certificate.
Where should I position the certificate in the architecture?
It depends on your security requirements, but it's totally fine to create an HTTPS commutation between Client and Load Balancer, and an HTTP communication between Load Balancer and Server. In this case, you will only need a public certificate generated by ACM.
If your security requirements need to create a secure communication end-to-end (e.g. HTTPS communication between LoadBalancer and Server), you will need to install the same private certificate in all servers and upload your private certificate in ACM.
While searching I sow AWS Certificate Manager. I am wondering how is it different ?
The only difference is that you don't need no buy a certificate if you only use in Load Balancers / API Gateway, etc but if you want to download the certificate to install in your on-premise Load Balancer or in the servers, you will have to pay $400 for each certificate.
And when I buy a certificate can I use a single certificate with a different account? (Example: can I have the same certificate set up for Staging and multiple production environments)
Yes, you can. But keep in mind that you will need to create a wildcard certificate to support multiple DNS names.
The preferred service to use is AWS ACM.
You can either upload your own certificate (i.e. purchase it then upload) or have AWS generate and manage it for you.
If you let ACM manage and generate it will regenerate ahead of its expiry and handle the rotation on each attached resource.
It is important to note that an ACM certificate can only be bound to the following resources for HTTP traffic:
ELB
CloudFront
API Gateway
Once it is connected to these you can use SSL offloading (the TLS connection is terminated at the resource rather than the instance) to connecting to the backend resources over plain HTTP.
You should be aware that if you want to serve traffic directly from an EC2 you will not be able to use ACM public CA and instead would limited to one of the following:
Buy certificate and deploy to all servers
Use a service like certbot on each server
In addition you can use certificates that are hosted in IAM but this is considered legacy with less features than ACM.
I am trying to use an amazon SSL certificate for my app. Currently, I have dockerized application hosting on the AWS server with envoy front-proxy. I am using lets-encrypt SSL certificates for a trusted domain certificate. Now I want to switch it with amazon's SSL certificates.
I am exploring this but I didn't get any clear idea. This blog show how to enable traffic encryption between services in AWS App Mesh using AWS Certificate Manager. but they have not mentioned how to do it with enovy proxy.
For envoy, we have to provide cert and key files. But as per this question, we are not able to download these files from amazon. Is it possible to use the Amazon certificate with envoy front-proxy? If yes then can you please give me the idea/example of how to do it?
Thanks in advance..
Only AWS Services can use AWS SSL Certificates. If you want to use an AWS SSL Certificate for TLS/HTTP traffic you would use an Application Load Balancer to handle the certificate and send it to your Envoy proxy hosted on an EC2 box. Ideally you would keep the network traffic encrypted which would require you to use a LetsEncrypt certificate between the Application Load Balancer and EC2.
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.
