Software-defined networking (SDN) can be applied for cloud-managed networks that use dynamic configuration to improve performance and monitoring. It offers greater centralization than traditional networks, allowing administrators to achieve the flexibility and ease of troubleshooting they need for cloud network monitoring with increasingly complex architecture. SDN accomplishes this by...

In my daily work with customers, Partners and Carriers from different countries in Central and South America, I’ve found that companies are indeed implementing this type of technology, with the suite of features oriented to ensuring their networks are operational. After this initial infatuation and starting implementation, what...
