There are quite a few developments in the Enterprise IT space that have changed the way WAN networks are deployed. Gone are the days when MPLS or leased line circuits would suffice. Also, BFSI sector sees the high Opex of VSAT links as a big hurdle when scaling up. 

Enterprise IT applications have become more cloudified, SaaS driven leading to demands on the WAN networks to be as dynamic and resilient as possible.

Enter the Software Defined Wide Area Networks (SD-WAN) which are the ideal solution for the above-named requirements of Enterprises. Enterprise expects its WAN to enable high speed consumption of applications, irrespective of where those applications are and from where those applications are accessed. With the adoption of SaaS and Cloud growing at a rapid pace, Enterprise requires more internet bandwidth rather than bandwidth to its data centers. It requires high quality bandwidth at each location without the hassles of feasibility at those locations. It requires a SD-WAN that can mix the legacy world of MPLS that connected its locations to its data centers with internet at each location.

M2M has partnered with some of the leading SD-WAN technology providers to bring this solution to our customers. These include Customers in the Mining Industry where due to implementation of ERP across all end-points, the need for an SD-WAN was felt imperative, Banks with remote rural branches, Oil Marketing companies with many thousand retail outlets and so on.

The SD-WAN solution typically comprises of a Hub & Spoke model with edge SDWAN routers and central Hub with a Gateway at the Data-center. The orchestration and management is done by either a cloud-based server or On-Premise server depending upon the organization requirements.
