I googled and reviewed all info on the letsencrypt’s site, and still can’t get a clear answer about certificate creation / renewal limits. Please try me to understand. Here is my use-case:
My company, let’s name it “xxx”, is a SaaS product which is provides kind of VPN services to its customers. Without going into much details, we are:
- Create for each customer a dedicated DNS record with a dedicated subdomain (e.g. a.xxx.com, b.xxx.com, c.xxx.com)
- Since TLS termination performed by a customer, we supposed to provide our customers a certificate, which they supposed to install on their side. Since each customer not allowed to see traffic of another, we have to generate a dedicated certificate per subdomain (we can’t use SAN certificates).
The process of DNS record creation and certificate generation supposed to be fully automatic, without any human intervention.
Now, as I understand, you are limiting to 50 certificates generations per week. Since each subdomain must receive its own dedicated certificate, is that means I limited to max 50 new customers per week?
What about renewals? How they are counted? Assuming I using all “50 per week” limit for generating new certificates - is that means I will be not able to renew any of existing certificates?
Is there a way to make some commercial agreement to remove \ extend these limits? We talking about potential need of generating and renewing dozens of certificates per day.
