Docker vs Webpack: What are the differences?
Introduction
This Markdown code provides a comparison between Docker and Webpack, highlighting the key differences between the two technologies.
- Containerization vs. Module Bundling: The primary difference between Docker and Webpack lies in their core functionalities. Docker is a containerization platform that allows applications to run in isolated environments called containers, while Webpack is a module bundler primarily used for JavaScript applications.
- Application Deployment vs. Development: Docker focuses on application deployment, providing a consistent and reproducible environment for running applications. On the other hand, Webpack is primarily used in the development phase to bundle JavaScript modules and optimize assets for efficient delivery to the browser.
- Isolation vs. Optimization: Docker containers provide application isolation by packaging the entire environment, including the operating system and dependencies, into a single unit. In contrast, Webpack optimizes files by analyzing dependencies and creating an optimized build for efficient serving to the client, without providing application isolation.
- Scalability and Portability: Docker enables easy scaling by allowing multiple containers to be run across different hosts, making it suitable for distributed systems. Webpack, on the other hand, is not specifically designed for scaling and is mainly used within the context of a single application or project.
- Runtime Overhead: Docker containers carry additional runtime overhead due to the need to run a separate operating system and manage isolation. This can result in heavier resource usage compared to using Webpack, which performs optimizations at the build stage and does not introduce additional runtime overhead.
- Use Cases: Docker is commonly used for deploying complex applications with multiple services, enabling smooth collaboration between development and operations teams. Webpack, on the other hand, is popular for bundling JavaScript modules and assets for web development projects, optimizing performance and improving development workflows.
In summary, Docker and Webpack serve different purposes in the software development lifecycle, with Docker focusing on application deployment and isolation through containerization, while Webpack is primarily used for bundling JavaScript modules and optimizing assets during development.
I could define the next points why we have to migrate:
- Decrease build time of our application. (It was the main cause).
- Also
jspm install
takes much more time thannpm install
. - Many config files for SystemJS and JSPM. For Webpack you can use just one main config file, and you can use some separate config files for specific builds using inheritance and merge them.
We mostly use rollup to publish package onto NPM. For most all other use cases, we use the Meteor build tool (probably 99% of the time) for publishing packages. If you're using Node on FHIR you probably won't need to know rollup, unless you are somehow working on helping us publish front end user interface components using FHIR. That being said, we have been migrating away from Atmosphere package manager towards NPM. As we continue to migrate away, we may publish other NPM packages using rollup.
lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.
