Whether it’s as simple as ensuring solid connectivity with a SaaS provider or designing a robust, secure, hybrid, and multi-cloud architecture, the enterprise wide area network is all about connecting us to our resources, wherever they are. So what does this mean for today’s enterprise network engineer?

Why is Cisco ACI replacing traditional networks? Companies are increasingly moving from traditional networks to SDN-based networks. spine-leaf topologies provide excessive-bandwidth, low-latency, non-blocking server-to-server connectivity.

Occasionally, customers report issues such as high latency or not achieving their subscribed bandwidth. To address these concerns, we certify the last-mile connection using iPerf3 for traffic and bandwidth analysis. We temporarily add the customers public IP to our firewall to enable communication between the client and server.

It could change your entire approach to network security, and help save your sanity. Gone are the days when it was simple and effective to connect remote sites with a perimeter firewall, or backhaul traffic to a datacenter to keep companies secure and functional. Firewall as a Service (FWaaS) is the future of network security.

The Dutch engineering company had built a global wide area network (WAN) out of MPLS and Internet services connecting 17 locations 14 in Europe and 3 in the Asia Pacific with about 800 mobile and field employees. Cloud applications were starved for bandwidth as they were backhauled across a 10 Mbits/s connection to the datacenter.

With a hybrid WAN, two different types of network services connect locations. Usually, one network service is MPLS while the other is typically an Internet connection. Offloading traffic from MPLS allows for reductions in monthly bandwidth costs and to turn up new installations faster by leveraging indigenous Internet access link.

No surprise, I suppose, as MPLS costs can be more than 5x the cost of Internet bandwidth. With such high disparity in bandwidth costs, backhauling Internet traffic makes little sense.
