With the extension of your current infrastructure to the Azure services, you need to think about the topic of connectivity. Azure provides and supports three types of connection, two server, and one client-focused option. A server connection is always between your current network infrastructure and Azure virtual networks. The three connection types are as follows:
Site-to-Site VPN (server-focused)
Express Route (server-focused)
Point-to-Site (client-focused)

Configuration of a few clients that need to access the virtual network
Administrative remote access
Combinations of S2S connections with small groups of single clients (small branches)
