Without Kubernetes, during a heavy traffic spike like Black Friday, servers can crash, resulting in site downtime, lost sales, and a negative user experience.
Kubernetes addresses these issues by providing auto-scaling, load balancing, high availability, automatic recovery, and rolling updates without downtime.
With Kubernetes, frontend, backend, and database replicas can be automatically scaled up based on incoming load, traffic can be evenly distributed to prevent overload, and crashed containers can be automatically restarted.
Kubernetes also ensures app availability during updates, monitors containers' health, and replaces failed containers to maintain system stability.
