Week 4 - Amazon VPC

Amazon Virtual Private Cloud (Amazon VPC) is a service from AWS that lets you create your own private network in the cloud. It works like a traditional data center but gives you the flexibility and scalability of the cloud. With a VPC, you can set up parts of your network called subnets, choose your own IP address ranges, and control how data moves in and out using route tables and gateways. For example, an internet gateway lets your resources connect to the internet, while a VPC endpoint lets you privately connect to AWS services without going through the internet.

Every AWS account comes with a default VPC so you can start quickly, but you can also create your own custom VPC with settings that meet your specific needs. You can connect your VPC to other networks, like other VPCs or even your company’s on-premises network, using features like VPC peering, VPNs, or transit gateways. AWS also offers tools like traffic mirroring to help you monitor network activity and VPC flow logs to track what’s happening with your network traffic.

The best part is using a VPC is free, though some features like using public IP addresses or NAT gateways, may have extra costs. Amazon VPC is a powerful way to build a secure, flexible, and customizable network in the cloud, giving you full control over how your resources connect and communicate.

Week 5 - Can the Cloud Keep Up

The Internet of Things (IoT) is exploding, connecting everything from smart home devices to industrial machines. This rapid growth creates huge amounts of data that need to be processed, stored, and managed efficiently. Many experts believe the cloud will play a key role in handling this flood of information. Cloud computing offers flexible resources and scalable infrastructure that can adjust to the growing number of IoT devices. However, there are challenges to overcome. For example, IoT devices often generate real-time data that needs quick processing, which can be difficult when relying on distant cloud servers. This has led to the rise of “edge computing,” where data is processed closer to the devices themselves to reduce delays. Security and privacy are also major concerns. As more devices connect to the cloud, protecting data from cyberattacks becomes critical. The cloud must evolve to offer stronger security measures to keep IoT data safe. In the future, a combination of clo...

Week 8 - Relational Database

A relational database is a system used to store and organize information in a structured way. Instead of keeping everything in one long file, it separates information into tables. These tables work a lot like spreadsheets, with columns that describe the type of data, such as a name or a date, and rows that contain the actual data. What makes relational databases special is that the tables can be connected, or related, to each other. For example, one table might hold customer information, while another stores their orders, and the database links those pieces together. This approach was first introduced in 1970 by E. F. Codd, a researcher at IBM. Before that, information was often kept in flat files, which made it hard to find specific details or make connections between different pieces of data. Codd’s idea completely changed how businesses manage large amounts of information. To interact with a relational database, people use a language called SQL, or Structured Query Language. It al...
