Docker features and specs

• Portability
  Docker containers are designed to run consistently across different environments such as development, testing, and production, ensuring that software behaves the same regardless of where it's deployed.
• Efficiency
  Docker containers share the host OS kernel and use fewer resources compared to traditional virtual machines, which allows for faster startups and reduced overhead.
• Isolation
  Containers encapsulate the application and its dependencies in a separate environment, which minimizes conflicts between different applications' dependencies.
• Scalability
  Docker makes it easier to scale applications quickly and manage resource allocation dynamically, which is particularly useful for microservices architectures.
• Continuous Integration and Deployment
  Docker facilitates CI/CD processes by making it easier to automate the deployment pipeline, resulting in faster code releases and more frequent updates.
• Community and Ecosystem
  A vast community and a rich ecosystem of tools and pre-built images in Docker Hub, enabling you to quickly find and reuse code and solutions.

Possible disadvantages of Docker

• Complexity
  While Docker can simplify certain aspects of deployment, it adds a layer of complexity to the infrastructure that might require specialized knowledge and training.
• Security
  Containers share the host OS kernel, which can pose security risks if an attacker gains access to the kernel. Proper isolation and security measures must be implemented.
• Persistent Data
  Managing persistent data in Docker can be challenging, as containers are ephemeral and the default storage solutions are not always suitable for all applications.
• Monitoring and Debugging
  Traditional monitoring and debugging tools might not work well with containerized applications, requiring specialized tools and approaches which can complicate troubleshooting.
• Performance Overhead
  Although lighter than virtual machines, Docker containers can still introduce performance overheads, especially when multiple containers are running simultaneously.
• Compatibility
  Not all software and systems are fully compatible with Docker, which can limit its use in certain legacy applications and complex environments.

Jekyll features and specs

• Speed and Performance
  Jekyll generates static websites, which means they load faster compared to dynamic websites. No database queries are required, reducing server overhead and improving performance.
• Security
  Static sites have a smaller attack surface compared to dynamic sites because they don't rely on databases or server-side code. This means fewer vectors for potential compromises.
• Simplicity
  Jekyll setups are relatively straightforward, especially if you are comfortable writing in Markdown and HTML. This can make it easier to manage and maintain your website.
• Integration with GitHub Pages
  Jekyll is designed to work seamlessly with GitHub Pages, allowing you to host your website for free with automatic deployment directly from your GitHub repository.
• Customizability
  Jekyll allows for extensive customization through its support for plugins, themes, and templates. This can be helpful to create a unique look and functionality for your website.

Possible disadvantages of Jekyll

• Learning Curve
  While Jekyll is simpler than some other static site generators, it does require some familiarity with the command line, version control (Git), and YAML configuration.
• Build Time
  For large websites, the build times can become lengthy, which can slow down the development process, especially if you are making frequent updates.
• Lack of Real-time Content Updates
  Since Jekyll generates static sites, real-time content updates (e.g., comments, dynamic forms) aren't natively supported and require third-party services or additional tooling.
• Dependence on Ruby
  Jekyll is built with Ruby, so you will need to have Ruby installed and occasionally deal with Ruby-specific issues. This might be a drawback for developers who are not familiar with the Ruby ecosystem.
• Limited Built-in Functionality
  While Jekyll is very flexible, it doesn’t have built-in support for many features out of the box, which might require you to manually implement or rely on plugins.
