Container Is the New VM: The Paradigm Change for Cloud Computing

Explore the paradigm shift from virtual machines to containers in cloud computing through this informative conference talk. Discover how containers have become the new atomic unit for firewalls, load balancers, and auto-scaling, replacing traditional VMs. Learn about the challenges of adopting containers when cloud provider services are still VM-centric, and gain insights into configuring load balancers, managing firewalls, and implementing security measures in a containerized environment. Follow the speakers as they guide you through the necessary mindset changes for successfully migrating to containers, drawing from their experience with multiple companies. Understand the biggest hurdles cluster administrators face when transitioning to containers in the cloud, including load-balancing, firewall management, and secure autoscaling. By the end of this talk, gain the knowledge needed to confidently embrace containers as the new VM and navigate the evolving landscape of cloud-native computing.
