Exploring Nginx features for my client Cloud requirement
June 19, 2020 02:50AM
Hi there,

I am exploring the features of Nginx features and doing a POC with all the possible use cases. If all goes well, probably there would be a huge investment on the Nginx to use it our cloud based architecture.

Currently exploring an option on TCP SSL termination on Nginx for a SSL connection from Java JDBC client. Facing issues, any guidance would be speed up my POC and complete it.

I'm using nginx on Windows 10 and using the opensource version.
