What is the main argument of the text?
Traditional virtual machines are still the best for web hosting.
Modern web servers should be deployed as lightweight containers managed by orchestration systems.
Bare-metal servers are the future of cloud-native computing.
Web servers no longer need to scale dynamically.
The web should return to monolithic server models.
According to the text, what is the key difference between containers and virtual machines (VMs)?
Containers require more boot time than VMs.
Containers run a separate operating system for each instance.
Containers share the host kernel, reducing overhead and improving efficiency.
Containers are larger and more complex than VMs.
Containers cannot run multiple applications at once.
Why are container orchestration systems like Kubernetes considered essential?
They help design websites faster.
They automate deployment, scaling, and recovery of web servers.
They replace all need for network engineers.
They make containers run slower but safer.
They eliminate all software updates.
What happens when a containerized web server instance fails?
The entire system must be rebooted manually.
The orchestration system automatically replaces it.
Users must report it to developers.
The failure is ignored until the next update.
The web application stops completely.
From the text, we can infer that containerization improves business operations because it _____
reduces operational speed
requires fewer servers to run applications
allows faster updates and lower costs
makes systems more complicated
prevents application development
