Which key aspect does ZTunnel 2.0 use for faster transport capabilities?

ZTunnel 2.0 leverages the DTLS (Datagram Transport Layer Security) protocol for faster transport capabilities. DTLS is designed to provide end-to-end communications privacy for applications that are sensitive to delays, which is crucial in a cloud environment where speed and performance are key considerations. By utilizing a connectionless transport, DTLS reduces the overhead associated with establishing and maintaining connections, thus allowing for quicker data transmission compared to traditional TCP connections.

In contrast to SSL encryption, which focuses primarily on securing data in transit rather than optimizing transport speed, the DTLS protocol ensures data integrity and security while also enhancing responsiveness. Additionally, HTTP headers and traditional TCP connections do not offer the same advantages in terms of speed and efficiency that DTLS brings to the table. Hence, the use of DTLS is a critical factor in ensuring that ZTunnel 2.0 can meet the demanding performance needs of modern cloud applications.
