Elastic Network Capacity (Erl, Naserpour)
How can network bandwidth be allocated to align with actual usage requirements?
Problem
Network bandwidth is often fixed, resulting in performance bottlenecks, runtime exceptions and failure when bandwidth capacity is reached.
Solution
A system is established to dynamically increase or decrease the amount of network ports or network bandwidth in response to actual bandwidth usage.
Application
Cloud consumer network traffic is isolated and each cloud consumer is allocated its own network ports which are retrieved from and returned to a network pool, as per usage requirements.
Mechanisms
Automated Scaling Listener, Cloud Usage Monitor, Container, Hypervisor, Logical Network Perimeter, Pay-Per-Use Monitor, Resource Replication, Virtual Server
