Question
Alex, a cloud security engineer working in Eyecloud Inc. is tasked with isolating applications from the underlying infrastructure and stimulating communication via well-defined channels. For this purpose, he used an open-source technology that helped him in developing, packaging, and running applications; further, the technology provides PaaS through OS-level visualization, delivers containerized software packages, and promotes fast software delivery. What is the cloud technology employed by Alex in the above scenario?

Why each option
This question identifies the containerization platform that isolates applications from infrastructure using OS-level virtualization and enables fast software delivery. Docker is the open-source technology that matches all the described characteristics including PaaS delivery and containerized packaging.
A virtual machine abstracts an entire operating system using hypervisor-based hardware virtualization, which is heavier than OS-level containerization and does not natively provide the packaging and fast-delivery features described.
Serverless computing abstracts infrastructure entirely and executes functions on demand, but it does not involve developing, packaging, or running containerized software images.
Docker is an open-source platform that uses OS-level virtualization to package applications and their dependencies into portable containers, isolating them from the underlying infrastructure. It enables developers to build, ship, and run applications consistently across environments through well-defined channels such as container images and registries. Docker underpins PaaS offerings and promotes rapid, repeatable software delivery by standardizing the runtime environment.
Zero trust network is a security model that enforces strict access verification for all users and devices, and is not a technology for containerizing or packaging application workloads.
