How do we build a secure architecture on AWS?

In the world of cloud development and deployment, it's essential to not only think about functionality, but also security. Welcome to this exploration of designing a secure architecture on AWS! As we move forward, we'll discover how to ensure that your projects are not only efficient, but also secure and economically viable.

What is the principle of last privilege?

The key to a secure architecture on AWS lies in the principle of "last privilege". This approach consists of granting each resource or user only the minimum permissions necessary to do their job. In this way, we avoid the common mistakes of granting excessive permissions, such as with admin users.

• Reviewing permissions: Instead of starting with all permissions and restricting later, we start with minimal permissions and grant more only if necessary.
• Built-in protection: This approach not only minimizes the risk of unauthorized access, but also simplifies infrastructure management and monitoring.

How to manage costs on AWS?

One of the advantages of working with AWS is the ability to manage costs efficiently, but it is also essential to avoid billing surprises.

To make sure you keep costs in check, you can set up budget alerts:

1. Log in to AWS: Log in to the AWS console as the root user, who has full privileges.
2. Go to Billing and Cost Management: Although it contains valuable information on cost analysis, we will focus on the Budgets and Planning part.
3. Create a budget: Select "Create budget" and opt for the "zero spend budget" template to ensure you don't generate expenses.
4. Timely notifications: Specify an email to receive alerts if any expenses are incurred, allowing for quick actions such as turning off unnecessary instances.

This approach ensures that you will be able to work within the free trial and react to any unforeseen spending attempts.

How to create and manage access control lists?

Access Control Lists (ACLs) are vital tools for defining who or what can interact with elements of your AWS architecture. While they are not the security principle itself, they function as the mechanism for implementing it.

• Precise definition: Detail which users and resources have access to which parts of your infrastructure.
• Strategic use: Implement ACLs as part of your authorization scheme, ensuring that only the necessary elements have interaction and access as required.
• Constant monitoring: Keep regular track of these lists to adapt them as your needs or project scope change.

What to consider when designing the architecture in AWS?

With budget preparation and an understanding of permissions, you're ready to start building.

• Pre-planning: Before you head to AWS, define the key elements of your solution and the interactions between them.
• Archive consideration: Utilize RDS instances and other resources by keeping them within the free trial period.
• Architectural dynamism: Build an architecture that can grow or shrink based on demands and adjust to changes in application or traffic.

Each of these approaches not only ensures effective technical implementation, but also solid budget protection. So go ahead, assemble your architecture securely and efficiently on AWS. Your project will be robust and reliable, allowing you to grow with confidence - keep learning and building!
