The VSM is the Edge Controller of Abloomy’s Smart-Edge architecture. It can be either an on-premises appliance or deployed on commercial off-the-shelf servers in the data centers of customers or public cloud providers. Under the control of the CSP or ACS, the VSM is the execution node of Abloomy’s cloud service. With programmability, the VSM can be orchestrated with cloud-managed functions hosted by the ACS or CSP, based on the policies of the customer’s cloud account. It can execute these functions at the edge closest to the customer, in infinitely large-scale distributed deployment scenarios, to guarantee low latency, security, and data privacy—the fundamental requirements for any IoT application. With these cloud-managed functions, the VSM not only provides all the functions of a traditional WiFi controller such as network management and optimization, NAC and other wireless security functions but also provides portal, authentication and WiFi marketing functions. With SD-WAN, firewall, NAT, VPN and routing functionalities, it also functions as a network gateway to construct a performance-assured network infrastructure that connects employees, branches, HQ, DCs, and the cloud, all while ensuring high security, deep visibility, and 100% centralized programmability. The VSM is plug-and-play and makes the network seamlessly scalable. Once configured, the VSM can work independently even after losing connection with the ACS and CSP, and has N+N redundancy, creating an extremely reliable shared computing resource pool.
