Be it power supplies, servers, routers, load balancers, proxies, or any other physical and virtual network components, the horizontal scaling that redundancy provides is the ultimate safety net in the presence of failure or atypical traffic demands.

Rather than collecting only flow data from routers, or only eBPF information from containers, the fact that application traffic traverses so many devices means we need much more data to get an accurate view of what’s happening. Some of these devices an enterprise network engineer owns and manages, and a lot of it they don’t.

Redundant Provider Edge (PE) MPLS-enabled routers, switches, and other appliances were needed in each point-of-presence (PoP). Locations connecting to the UberNet, for example, are directed to the closest available PoP by DNS. With limited competition, providers had little incentive to reduce their fees.

Failover between lines with MPLS is based on DNS or route convergence, which takes too long to sustain a session. Bottom Line Conventional enterprise wide area networks are a hodge podges of routers, load balancers, firewalls, next generation firewalls (NGFW), anti-virus and more.

The Mirai botnet that launched the DDOS attack DYNs DNS, for example, used home routers, cameras and other IOT devices. Its not just that our users increasingly work from the home. Its also that homes house new, more powerful devices that are being used to launch attacks against us.

As an example of what can happen, the Mirai malware set loose in late 2016 created a botnet of IoT devices that included ordinary consumer devices such as security cameras, routers, and other home use IoT devices purposely designed to take websites and entire networks offline. The scale of the initial Mirai-based attack was eye-opening.

Bad hardware (the switch or router port). Firewall configured to drop packets (all ICMP is dropped). Overwhelmed router. Congestion in the form of high-connection utilization or an overworked router in the path is another common source of trouble. The cloud is made up of thousands of routers. UDP vs. TCP.

For e.g., if accessing file system over WebDAV or FTP has performance issues, and it will take 4 hours to fix, then for those 4 hours, you can just kill FTP/WebDAV at kong/firewall and ask customers to use web UI or other mechanisms to work. Which firewall product do you use? Which DNS service do you use? Palo Alto networks.
