A nice cheat sheet of different monitoring infrastructure in cloud services.

This cheat sheet offers a concise yet comprehensive comparison of key monitoring elements across the three major cloud providers and open-source / 3rd party tools.

Let's delve into the essential monitoring aspects covered:
- Data Collection: Gather information from diverse sources to enhance decision-making.
- Data Storage: Safely store and manage data for future analysis and reference.
- Data Analysis: Extract valuable insights from data to drive informed actions.
- Alerting: Receive real-time notifications about critical events or anomalies.
- Visualization: Present data in a visually comprehensible format for better understanding.
- Reporting and Compliance: Generate reports and ensure adherence to regulatory standards.
- Automation: Streamline processes and tasks through automated workflows.
- Integration: Seamlessly connect and exchange data between different systems or tools.
- Feedback Loops: Continuously refine strategies based on feedback and performance analysis.

Over to you: How do you prioritize and leverage these essential monitoring aspects in your domain to achieve better outcomes and efficiency?

1. 𝑲𝒆𝒓𝒏𝒆𝒍: The core that directly controls hardware like processors, graphics cards, and network adapters.

2. 𝑺𝒉𝒆𝒍𝒍: Acts as a bridge between users & the kernel, featuring popular options like Bash, Zsh, and Fish.

3. 𝑼𝒕𝒊𝒍𝒊𝒕𝒊𝒆𝒔: Powerful tools like grep, ls, and systemctl that manage system operations.

4. 𝑨𝒑𝒑𝒍𝒊𝒄𝒂𝒕𝒊𝒐𝒏𝒔: User-facing programs like web browsers, media players, and office suites.

A simple, layered design making Linux powerful and flexible! 🐧

From Application to Physical Layer, learn how these models structure data flow, communication, and networking! 🚀

OSI layers: Physical, Data Link, Network, Transport, Session, Presentation, Application.
TCP/IP maps to: Network Access, Internet, Transport, Application.

🔍 Key protocols:
- HTTP, FTP, DNS (OSI)
- TCP, IP (TCP/IP)

Both models ensure data transmission & communication! 📡💻
