This will be the part one of cloud network technologies to share with you.
There are two main topologies to connect to the cloud.

  • Point to Site VPN
  • Site to Site VPN

Point to Site VPN

P2S represent a situation where you have hosted your infrastructure in Cloud and try to use the cloud services or try to access your company infrastructure hosted in the cloud from your device, say your laptop.

Explanatory by the name itself (point – to – site) one or more users connect to the cloud through a VPN. You may be working from home or any place you prefer. The connection is created as a tunnel (that is what VPN is) using a VPN client software. By far this is the hardest VPN to configure on azure with respect to the S2S connection. The connection will authenticate using a client certificate generated by a root certificate.

Site to Site VPN

This topology is the most widely used and easiest to configure. If you need an idea of Hybrid Cloud feel free to refer to this article on Hybrid Cloud.

S2S VPN is used on companies that fall into any of the following:

  • A company with Hybrid-cloud infrastructure

Those companies have an onsite DC and they have extended their infrastructure to the cloud.
