I ask this because there are many resources out there for Lets Encrypt to auto renew and deploy (via Lambda) to ELBs. Doesn't AWS' Certificate Manager do the same thing?

Q: What can I do with AWS Certificate Manager?
...
ACM manages certificate renewals and certificate deployment for you.
However the AWS docs don't talk about this at all.
So if I understand this correctly...
I request a cert
Verify the cert in my email
Manually deploy the cert
ACM will every year renew my cert and deploy my cert back to all the resources I deployed it to previously
Is this correct? Is there documentation that talks about this explicitly?
Any direction on this would be helpful.
If you are using AWS SSL Certificates from Certificate Manager, renewal is automatically handled and changing the certificate from your application load balancer or CloudFront is not required.
Check this documentation for more details.

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 am very new to this and struggling to understand AWS.
I had a single domain foo.mydomain.com. This was registered in Route53. And there was a certificate in AWS Certificate Manager that mapped to it.
Now I have two domains foo.mydomain.com & bar.mydomain.com. I have registered the latter in Route53. And I have requrested and received a new certificate from AWS Certificate Manager. This one maps to both domains (via the "additional names" property).
How can I simply disable the old certificate and enable the new certificate?
I want the values for In use? above to be swapped.
You need to go to the services where you are utilizing these certificates (Load Balancers, CloudFront distributions or API Gateways) and change the certificate they are using there.
AWS Certificate Manager manages the SSL/TLS certificates. In general certificates are configured and consumed on the services like ALB (application load balancer), API Gateway, Virtual Machine, Cloudfront etc. If you would like to update the certificate, modify the configuration on one of the above services as applicable in your case. While changing configuration you have to choose the right certificate from ACM. Once update is successful you will see the status in ACM.
Here is an AWS documentation explains how to install/Update SSL Certificates:
https://docs.aws.amazon.com/elasticloadbalancing/latest/application/listener-update-certificates.html
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.
Can I use a certificate from AWS Certificate Manager to use it with API Gateway and my Custom Domain Name?
How do I get the certificate body, private key and chain out of the certificate from the AWS Certificate Manager?
As you saw in the forum post, it's not possible now. ACM integration is something we want to do and it's on our backlog, but I don't have an ETA for you at the moment.
ACM is now integrated with API Gateway!
