Four Reasons Why SD-WAN Makes Sense
Virtualization has revolutionized the data center, and now the next
step is revolutionizing the network. Central to the networking
revolution is software-defined networking (SDN), which allows network
administrators to virtualize their networking hardware and bring added
agility and cost savings. Although all networking of all types can benefit from SDN, one area
ripe for adoption is the wide area network (WAN). SD-Wan, as
software-defined WAN is called, can enable businesses to harness
virtualization and reap the benefits not only of improved agility and
cost, but also other benefits. Companies such as CloudGenix are pushing forward with SD-WAN technology and giving businesses an easy adoption path.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things.
