Evictor is an automated solution that helps Kubernetes clusters achieve higher node utilization and reduce costs by continuously compacting pods into fewer nodes, creating empty nodes that can be removed following the Node deletion policy. This process is also known as bin packing. Evictor works by identifying one node as a candidate for eviction, moving pods to other nodes through a mechanism called "bin-packing," and then deleting the empty node once it's no longer needed. By automating pod eviction and scheduling, teams can save time and costs associated with managing their Kubernetes clusters. Bin packing algorithms aim to find the best solution to pack a set of items into as fewest containers as possible, which in this context means nodes. The goal is to maximize node utilization and reduce cloud spend by running workloads on fewer virtual machines. By using automated solutions like Evictor, teams can achieve higher node utilization and lower cloud bills.
