A web-application company recently released some new marketing promotions without notifying the IT staff. The systems administrator has since been noticing twice the normal traffic consumption every t

A firewall controls network access and security policies but does not increase compute or container capacity to handle higher traffic volume.

Switches are layer-2 network devices that forward frames between hosts and have no role in scaling application resources to meet increased demand.

Ballooning is a hypervisor memory-reclamation technique used in virtual machines to redistribute memory between guests, not a mechanism for scaling containerized applications under traffic load.

Autoscaling automatically provisions and deprovisions container instances in response to real-time traffic metrics, ensuring the environment can handle doubled traffic loads every two hours without manual intervention. It directly addresses the root cause - insufficient capacity during traffic surges - by elastically scaling resources up or down based on predefined thresholds.
