With the explosion of application traffic and the multiplication of data centre workloads during the last decade, east-west traffic greatly increased and ended up impacting the traditional north-south based architectures. This raised the need to review the entire data centre architecture while keeping the goal of meeting performance, security, and monitoring requirements.
From a performance and security perspective, rather than shunting the traffic to centralised security and management blocks within the data centre (which might cause performance issues) or accepting uncontrolled zones, the forwarding and security intelligence can be distributed throughout the data centre.
Innovations like DPDK already…
