In this section, you'll explore AWS messaging services and cloud monitoring fundamentals. You'll begin by learning about Amazon Simple Queue Service (Amazon SQS) and how message queues help decouple application components and support reliable communication. As you progress, you'll explore Amazon Simple Notification Service (Amazon SNS) and understand how it enables message delivery and notifications to multiple subscribers. You'll also gain hands-on experience using SQS and SNS to understand their core features and configuration. The section further introduces Amazon CloudWatch and its role in monitoring AWS resources, collecting metrics, and providing visibility into application and infrastructure performance. By the end of this section, you'll have a solid understanding of AWS messaging and monitoring services, enabling you to support reliable application communication and monitor cloud resources effectively.

In this section, you'll explore AWS observability, auditing, and infrastructure automation. You'll begin by gaining hands-on experience with Amazon CloudWatch and learning how to monitor AWS resources and examine operational metrics. As you progress, you'll explore AWS CloudTrail and understand how it records account activity and API events to support auditing, security investigations, and compliance requirements. You'll also gain practical experience working with CloudTrail. The section further introduces AWS CloudFormation and infrastructure as code, helping you understand how templates can be used to define and provision AWS resources consistently. You'll also create a CloudFormation stack through a hands-on demonstration. By the end of this section, you'll have a solid understanding of monitoring, auditing, and infrastructure automation, enabling you to observe AWS environments and manage resources more consistently.

In this section, you'll explore AWS infrastructure management, database services, and API integration. You'll begin by learning how to update and clean up AWS CloudFormation stacks to manage infrastructure changes and remove resources when they are no longer needed. As you progress, you'll explore Amazon Relational Database Service (Amazon RDS) and Amazon DynamoDB, understanding their key features and use cases. You'll also gain hands-on experience launching and working with an RDS database and creating a DynamoDB table. The section further introduces AWS API Gateway and its role in creating, publishing, and managing APIs that connect applications with backend services. These topics will help you understand how AWS infrastructure, databases, and application interfaces work together. By the end of this section, you'll have a solid understanding of CloudFormation management, AWS database services, and API Gateway, enabling you to manage cloud resources and support data-driven applications more effectively.
