Network Access to the vSphere Web Service

Your client application can use the vSphere Web Services API to communicate with vSphere servers over HTTPS (HTTP over an encrypted Secure Sockets Layer connection) at port 443. HTTPS is the default protocol.

You can configure the server to support HTTP. Use HTTP access only for test or development environments, not for production. For information about how to configure the server to support HTTP access, see the vSphere Web Services SDK Developer’s Setup Guide.
