Containerization
/kənˌteɪ.nə.raɪˈzeɪ.ʃən/
noun — “packing your apps so they behave anywhere, like Tupperware for code.”
Containerization is the practice of encapsulating an application, along with its dependencies, configuration, and runtime environment, into a lightweight, portable container. Unlike traditional virtual machines, containers share the host operating system kernel but maintain isolation between processes, libraries, and configuration, ensuring consistency across development, testing, and production.
Virtual IP
/viːˈaɪˈpiː/
noun — "Very Important Packet, because some traffic deserves the red carpet."
VIP, Virtual IP, is a network concept where a single IP address represents multiple physical devices or servers. It allows load balancing, high availability, and failover configurations by routing traffic to the best available resource without clients needing to know the underlying infrastructure.
Graal Virtual Machine
/ɡreɪl viː ɛm/
noun … “Polyglot JVM for high-performance execution.”
Kernel-based Virtual Machine
/ˌkeɪ viː ˈɛm/
noun … “Linux-based virtualization for running multiple OS instances.”
Hypervisor
/ˈhaɪpərˌvaɪzər/
noun … “Manages virtual machines on a physical host.”
Docker
/ˈdɒkər/
n. “Ship it with the world it expects.”
Docker is a platform for building, packaging, and running software inside containers — lightweight, isolated environments that bundle an application together with everything it needs to run. Code, runtime, libraries, system tools, and configuration all travel as a single unit. If it runs in one place, it runs the same way everywhere else. That promise is the point.
