Do I need a private key?

What is a private key? All TLS certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients.

How does a private key get generated?

A sender encrypts data with the receiver’s public key; only the holder of the private key can decrypt this data. Computer cryptography uses integers for keys. In some cases keys are randomly generated using a random number generator (RNG) or pseudorandom number generator (PRNG).

How do I get a certificate from load balancer?

Associate an ACM SSL certificate with a Classic Load Balancer

1. Open the Amazon EC2 console.
2. In the navigation pane, choose Load Balancers.
3. Choose the Listeners tab, and then choose Edit.
4. For Load Balancer Protocol, choose HTTPS.
5. For SSL Certificate, choose Change.
6. Select Choose a certificate from ACM.

Can a server behind a load balancer use the same private key?

YES, you can use the same certificate and associated private key on all of your servers, if they are behind a load balancer or load balancing reverse proxy and if they are all serving content for the same domain.

What kind of certificate do I need for load balancer?

If you load balance on the HTTPS layer (L7), then you’d commonly install the certificate on the load balancer alone, and use plain un-encrypted HTTP over the local network between the load balancer and the webservers (for best performance on the web servers).

How to check the IP address of a load balancer?

To ensure that the load balancer can scale properly, verify that each subnet for the load balancer has a CIDR block with at least a /27 bitmask (for example, 10.0.0.0/27) and has at least 8 free IP addresses. Your load balancer uses these IP addresses to establish connections with the backend instances; for more information, see VPCs and Subnets.

How to attach Amazon EC2 instances to load balancer?

Then, associate the public subnets with your load balancer. Before you begin, note the Availability Zone of each Amazon EC2 Linux or Amazon EC2 Windows instance that you’re attaching to your load balancer. Create a public subnet in each Availability Zone that your backend instances are located.
