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:

I have one load balancer on the GCP.
my project uses multi-domain and it is possible that add domains on after.
when I create a certificate with the google-managed certificate, I can't edit the certificate and add a domain.
I know I can remove the certificate and create a new certificate.
but not good because domains will not be certified for a while.
Do I have to get a certificate from somewhere else?
Is it possible to get a certificate that I can add to that domain later without changing the public key and private key?
What is your suggestion?
Google Cloud HTTP(S) Load Balancers support multiple certificates. If you need to add another domain, create/add a new certificate.
Using Google-managed SSL certificates
I try to configure https on ALB with default amazon subdomain: some-unique-path.elb.amazonaws.com
The problem is that I can't find how to generate the ssl certificate for this domain: Amazon Certificate Manager does not allow to generate certificates for amazonaws subdomains.
Is there any way to make it without buying custom domain and configuring it for ALB?
To use ACM you must have domain which you control. From docs:
Before the Amazon certificate authority (CA) can issue a certificate for your site, AWS Certificate Manager (ACM) must verify that you own or control all of the domain names that you specified in your request.
There are some free domain providers which you could maybe use, but you have to have domain under your control. You can't use some-unique-path.elb.amazonaws.com, because this is AWS-owned domain and you have no rights to it.
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 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 brought a domain (not in AWS) and parked it on AWS. I also got a certificate in AWS Certificate manager, for a domain I use for a shopify store.
On the shopify admin, I see that SSL isn't available for the purchased domain.
Is there a way to connect the domain with the certificate if the server is actually on shopify ?
ACM certificates are only for use with CloudFront and Elastic Load Balancers. You could possibly setup a CloudFront distribution in front of your Shopify domain in order to use the certificate that way, but it's probably more trouble and expense than it is worth.
You might look at moving your DNS hosting to CloudFlare and using their free SSL service.
The SSL certificate generated from ACM are only for use into AWS service who you cannot move move that certificate to a Shophify server. Please refer this.
