Does each server behind a load balancer need their own SSL certificate? 5 Answers. If you have 5 web servers behind a load balancer () do you need SSL certificates for all the servers, It depends. If you do your load balancing on the TCP or IP layer (OSI layer 4/3, a.k.a L4, L3), then yes, all HTTP servers will need to have the SSL certificate installed.

How does SSL work with a load balancer? An SSL load balancer is a load balancer that also performs encryption and decryption of data transported via HTTPS, which uses the Secure Sockets Layer (SSL) protocol (or its successor, the Transport Layer Security [TLS] protocol) to secure HTTP data as it crosses the network.

Do I need an SSL certificate for each domain? Depending on your specific business needs, you can use both a SAN certificate or a multi domain wildcard SSL to secure multiple domains.

Note: The ALB and NLB limit excluding default certificates is 25. This limit can be increased.

Does each server behind a load balancer need their own SSL certificate? – Additional Questions

Do load balancers need SSL certificates?

If you use HTTPS/SSL listeners for your Classic Load Balancer, you must install an SSL certificate.

You must replace the certificate before its validity period ends.

Does SSL protect against man in the middle?

Is SSL certificate valid for subdomains?

Yes, if you have only 2-3 subdomains, you can get a multi-domain SSL certificate. Here, you need to treat your subdomains as separate SAN.

Can I move SSL certificate to another server?

Because SSL certificates are tied to specific domain names, you cannot simply transfer an SSL certificate you registered with one domain name to a server for a different domain name. Even if you keep the same server but change domain names, the certificate will still not work.

How do I install an SSL certificate on two servers?

Can you SSL without domain name?

Every website needs an SSL certificate these days to remain accessible via Chrome or Firefox. But can you get SSL without a domain name? Yes, you can! Instead of securing a domain, you can encrypt a public IP address.

Are SSL certificates tied to IP address?

SSL certificates are tied to a single IP address in so far as that you can only have one certificate bound to a given IP address. The certificates themselves are expected to match the Common Name (CN) which is typically the hostname entered into DNS and configured for the service (IMAP, HTTPS, SMTP, etc).

Who assigns SSL certificate?

SSL Certificates need to be issued from a trusted Certificate Authority (CA). Browsers, operating systems, and mobile devices maintain lists of trusted CA root certificates. The Root Certificate must be present on the end user’s machine in order for the Certificate to be trusted.
