Why Kubernetes Is So Popular in the Tech World

Galido

For a start, it provides easy optimization of infrastructural resources since it uses hardware more effectively. This tool automates deploying, scaling, and managing containerized applications on a cluster of servers (virtual or bare metal). Therefore, this allows users to save on hardware and data center costs.
