Chapter 1

Simplified network design

With changing market conditions, business need to evolve and so does their technology stack that supports the business. Monolithic data center designs are complex, making it hard for the operators to respond quickly to growing business needs.

With a complex network design, operators run into issues like overly complex automation, errors in topology, difficulty troubleshooting and inefficient management. A complex network design ends up costing an organization money in the long run due to dedicated resources troubleshooting often and managing few switches at once.

Modern data centers built on web-scale principles of Layer 3 with Cumulus Linux and Cumulus Routing on the Host have dramatically simplified network designs and have unified infrastructures.

These case studies shows exactly how companies like Campaign Monitor and SWITCH simplified their network infrastructure by adopting a highly scalable layer 3 Clos architecture. They standardized on Linux OS that gave them the ability to bring layer 3 benefits all the down to the host with Cumulus Routing on the Host.

By having the ability to configure and manage their network switches just like servers, customers like NTT and Shapeways streamlined their network environment, resulting in more efficient networking and lower costs.
