Es increíble ver a los aficionados y jugadores colombianos cantar el himno nacional con tanto amor y orgullo por su país y su cultura. Ojalá nuestros atletas profesionales mostraran ese mismo orgullo y respeto por su propio país.

Use the command netsh wlan show wlanreport to generate a "super fancy" wireless report about your connection. Just copy the file path provided, paste it into your browser, and explore a detailed breakdown of your wireless situation
@yourclouddude Love your content. Am studying for AWS CCP but fairly newby to tech. Can you recommend some top or favorite networking learning sites or favorites?
@elonmusk we may need your help in Bradenton, FL. Send @Starlink so the people of this corner of Manatee can survive this hell 😂. Im reading a book. Coincidentally its the chapter on Networking. The irony.
AWS feels confusing until you understand these 10 concepts clearly ☁️
Most beginners don’t struggle with AWS because it is “hard.”
They struggle because they learn services randomly.
Start with these concepts first 👇
1. Region
A Region is where your AWS resources live.
Example:
US East, Europe, Mumbai, Singapore.
Pick a region based on:
→ users
→ latency
→ compliance
→ cost
2. Availability Zone
An Availability Zone is a separate data center inside a Region.
If one AZ fails, another can keep your app running.
This is the base of high availability.
3. VPC
VPC is your private network in AWS.
Think of it like your own isolated cloud space.
Inside a VPC, you control:
→ IP ranges
→ subnets
→ routing
→ internet access
→ security rules
4. Subnet
A subnet is a smaller section inside your VPC.
There are usually two types:
→ Public subnet
→ Private subnet
Public subnet faces the internet.
Private subnet is protected from direct internet access.
5. Internet Gateway
An Internet Gateway lets resources in a public subnet connect to the internet.
Without it, your VPC stays isolated.
6. Security Group
A Security Group is like a firewall for your server.
It controls what traffic is allowed in and out.
Example:
Allow HTTP traffic on port 80.
Allow SSH only from your IP.
7. IAM
IAM controls access in AWS.
It answers:
→ Who can access AWS?
→ What can they do?
→ Which resource can they use?
Bad IAM = big security risk.
8. EC2
EC2 is a virtual server.
You use it when you need full control over the operating system, runtime, and server setup.
It is useful for:
→ apps
→ backend servers
→ testing
→ custom environments
9. S3
S3 is object storage.
Use it to store:
→ images
→ videos
→ backups
→ logs
→ static website files
It is not a traditional folder system.
It stores objects inside buckets.
10. Lambda
Lambda lets you run code without managing servers.
You write the function.
AWS runs it when triggered.
Great for:
→ automation
→ APIs
→ file processing
→ event-driven tasks
Simple AWS mental model:
IAM controls access.
VPC controls networking.
EC2 runs servers.
S3 stores files.
Lambda runs code.
CloudWatch monitors everything.
Don’t try to memorize AWS.
Understand what each service is responsible for.
That is when AWS finally starts making sense.

AWS in Plain English: Amazon S3 🪣☁️
The most used AWS service (for a reason).
What problem S3 solves
Apps need a safe place to store files:
images, videos, backups, logs, data.
Servers aren’t great at this.
What Amazon S3 is
A global object storage service where you store files as objects.
Think:
➡️ unlimited storage
➡️ highly durable
➡️ accessible from anywhere
How it works (simple flow)
Upload file → S3 stores it → app/users access it via URL
What you can store
• Images & videos
• PDFs & documents
• App backups
• Logs & data files
• Static website files
Real-world use cases
• Host a static website
• Store user uploads
• Backup databases
• Share files securely
• Data lake for analytics
Why companies love S3
• 99.999999999% durability
• Cheap compared to servers
• Scales automatically
• Fine-grained access control
Key concepts to know
• Buckets = containers
• Objects = files
• Storage classes = cost control
• Permissions = IAM + bucket policy
When NOT to use S3
• As a database
• For ultra-low latency processing
• For files needing frequent edits
💡 One-line takeaway
S3 is for storing anything, reliably and cheaply.
Networking fundamentals that can actually help you get hired in tech:
① Network → connects devices so they can communicate
② IP Address → unique address of a device on a network
③ IPv4 → common IP format like 192.168.1.1
④ IPv6 → newer IP format for more address space
⑤ MAC Address → hardware address of a network device
⑥ Router → connects different networks together
⑦ Switch → connects devices inside the same network
⑧ Modem → connects your network to the internet
⑨ LAN → local network inside home/office
⑩ WAN → network spread across large areas
⑪ DNS → converts domain names into IP addresses
⑫ DHCP → automatically assigns IP addresses
⑬ TCP → reliable communication protocol
⑭ UDP → faster but less reliable protocol
⑮ HTTP → protocol for web communication
⑯ HTTPS → secure version of HTTP
⑰ Port → entry point for network services
⑱ Firewall → controls allowed and blocked traffic
⑲ Subnet → smaller section of a network
⑳ CIDR → defines IP range size
㉑ Gateway → path from one network to another
㉒ NAT → lets private IPs access the internet
㉓ VPN → secure private connection over the internet
㉔ Ping → tests if a device is reachable
㉕ Traceroute → shows the path traffic takes
If you want to work in cloud, cybersecurity, DevOps, or IT…
Don’t skip networking.
Most tech systems fail, scale, connect, and secure themselves through networks.
Networking becomes easier when you stop memorizing terms
and start understanding how devices talk to each other.
25 Networking fundamentals you should know
① Network → devices connected together
② IP Address → device identity on a network
③ MAC Address → hardware identity
④ Router → moves traffic between networks
⑤ Switch → connects devices inside a network
⑥ DNS → converts domain names to IPs
⑦ DHCP → assigns IP addresses automatically
⑧ Subnet → smaller part of a network
⑨ Gateway → exit point to another network
⑩ Firewall → allows or blocks traffic
⑪ Port → entry point for an app/service
⑫ TCP → reliable data delivery
⑬ UDP → faster, less reliable delivery
⑭ HTTP → web communication
⑮ HTTPS → secure web communication
⑯ NAT → private IP to public IP translation
⑰ VPN → secure private connection
⑱ LAN → local network
⑲ WAN → wide area network
⑳ Bandwidth → maximum data capacity
㉑ Latency → delay in communication
㉒ Packet → small unit of data
㉓ Packet Loss → missing data during transfer
㉔ Load Balancer → distributes traffic
㉕ CDN → delivers content faster globally
Networking gets easier when you stop memorizing terms
and start understanding how data moves.
