In manufacturing, an end-to-end service or solution involves one company, as a service to another, managing all aspects of design and production.

end-to-end connectivity

In e-commerce, end-to-end connects people who want to sell and buy. This practice eliminates the layers of middlemen who extract value from the trade and increase the final price.

In computer communication, end-to-end refers to end points, called end systems or hosts.

In computer security, end-to-end means that sensitive data is encrypted all the way from the device side application back to the enterprise. Rather than relying on transport-level security (such as Secure Sockets Layer, or SSL), end-to-end security puts the power of strong encryption in the user's hands, all through a simple interface. This resolves the so-called “air gap” where sensitive data was previously decrypted at the gateway during translation for wireless protocols into Internet protocols.

End-to-end monitoring is the process of attempting to remotely access a web server or other Internet device from across the Internet, just as a real end user would, to verify that the server is accessible and functioning properly at all times. This approach can be used instead of, or as a complement to, local monitoring software run by the web administrator.
