AWS resources playground

Working with AWS resources can be a complex task, but this playground is designed to help you explore and understand various AWS services. Below, you’ll find a collection of resources, guides, and examples to get you started with AWS, specifically focusing on AWS certification. However, befrore diving into the resources, it’s important to note that there are concepts that are transversal to them, let’s start with regions.

Regions

AWS regions are geographical areas where AWS has data centers. Each region is isolated from others to ensure high availability and fault tolerance. When you deploy resources in AWS, you can choose the region that best suits your needs based on factors like latency, compliance, and cost.


Regions -> Availability zones -> Data centers -> edge location

There are services that are global, such as IAM, Route 53, and CloudFront, which means they are not tied to a specific region. However, there are services that are region-specific, such as EC2, S3, and RDS.

Previleges

AWS operates on a principle of least privilege, meaning that users and applications should only have the permissions they need to perform their tasks. This is achieved through Identity and Access Management (IAM), which allows you to create users, groups, and roles with specific permissions. By carefully managing these permissions, you can enhance security and reduce the risk of unauthorized access to your AWS resources.

AWS cloud practitioner notes - Security

The AWS security model is shared meaning, AWS is responsible for the security of the cloud, and you, the customer is responsible for the security in the cloud. AWS controls the servers, data centers and all the layers in this section.
