Free certificates you can't use on EC2 virtual machines are basically worthless, at least for me.

Stop internalising your 1990s architecture limitations! You shouldn't need to pay for a Layer 7 load balancer for an application that doesn't need it. A 1-core web server VM can easily put out 1-2 Gbps of HTTPS traffic. You don't need SSL offload. A crypto accelerator card is not required. You don't need an appliance to do HTTPS. You can have end-to-end HTTPS without additional infrastructure. Both Windows and Linux can do TLS out-of-the-box. You don't need a vendor to give you special permission to have security. There is no need to pay GoDaddy or DigiCert for a certificate.

The vendors are pulling the wool over your eyes, convincing you that your out-of-date thinking is good and proper, and then charging you for the privilege of having the bare minimum security that should be free as standard.
