| 3 | 📘How To Code in Node.js
✍️ Authors: David Landup, Marcus Sanatan
🗓 Year: 2020
📄 Pages: 418
🧠 Node.js is a popular open-source runtime environment that can execute JavaScript outside of the browser. The Node runtime is commonly used for back-end web development, leveraging its asynchronous capabilities to create networking applications and web servers. Node is also a popular choice for building command line tools.
In this book, you will go through exercises to learn the basics of how to code in Node.js, gaining skills that apply equally to back-end and full stack development in the process.

| 14 | ▎Common DevOps Terms
1. CI/CD Pipeline: A set of automated processes that builds, tests, and deploys code changes from a repository to production.
2. Infrastructure as Code (IaC): Managing and provisioning infrastructure (servers, networks, databases) through machine-readable definition files (code) rather than physical hardware configuration.
3. Configuration Management: The process of maintaining consistency and control over software application configurations and their environments. Tools include Ansible, Chef, Puppet.
4. Containerization: Packaging an application and its dependencies into a self-contained unit (container) that can run reliably across different environments. Docker is the most common tool.
5. Container Orchestration: Automating the deployment, scaling, and management of containerized applications. Kubernetes is the industry standard.
6. Cloud Computing: On-demand delivery of IT resources over the internet with pay-as-you-go pricing. Major providers: AWS, Azure, GCP.
7. Virtual Machine (VM): An emulation of a computer system, allowing you to run an operating system and applications on top of another operating system.
8. API Gateway: A server that acts as a single entry point for all client requests to backend microservices, simplifying client interactions and providing security, monitoring, and traffic management.
9. Service Mesh: A dedicated infrastructure layer for making service-to-service communication safe, fast, and reliable, often used in microservices architectures. Examples: Istio, Linkerd.
10. Monitoring: The process of collecting, analyzing, and acting on data about system performance and health. Tools include Prometheus, Grafana, ELK Stack.
11. Logging: The process of recording events that occur within an application or system, crucial for debugging and auditing.
12. Alerting: The system that notifies the operations team when a critical event or threshold breach is detected in the monitoring system.
13. Scalability: The ability of a system to handle an increasing amount of work by adding resources. Horizontal (adding more servers) vs. Vertical (adding more power to existing servers).
14. Availability: The percentage of time a system is operational and accessible. Often measured in "nines" (e.g., 99.99% uptime).
15. Fault Tolerance: The ability of a system to continue operating, perhaps at a reduced level, rather than failing completely when some part of the system fails.
16. Disaster Recovery (DR): A plan and set of procedures to recover and protect a business IT infrastructure in the event of a disaster.
17. GitOps: An operational framework that codifies infrastructure and application configuration management in Git repositories, using Git as the single source of truth.
18. Testing (Unit, Integration, End-to-End): Different levels of automated testing to ensure code quality and functionality before deployment.
19. Release Engineering: The practice of managing and automating the software release process to ensure it is efficient, reliable, and repeatable.
20. Observability: The ability to understand the internal state of a system by examining its outputs (logs, metrics, traces). More comprehensive than just monitoring. | 396 |

9. Session Management: The technique used to manage user sessions in web applications, allowing users to stay logged in and maintain state across multiple requests.
10. Microservices: An architectural style that structures an application as a collection of small, loosely coupled services, each responsible for a specific business function.
11. Monolithic Architecture: A traditional software architecture where all components of an application are combined into a single, unified codebase.
12. CRUD (Create, Read, Update, Delete): The four basic operations of persistent storage, representing the fundamental functions of a database.
