Introduction to AWS Accounts and Global Infrastructure

Cloud computing is the on-demand delivery of IT services, enabling customers to provision IT resources such as infrastructure, platform, and software components to host and manage their applications. Cloud computing offers several advantages over traditional on-premises solutions, such as access to cutting-edge technologies, elasticity and scalability, and reduced management overhead. One of the biggest advantages of moving to the cloud is the ability to trade fixed costs for variable costs – this is because customers need not purchase any infrastructure hardware and instead rent capacity on the provider’s underlying infrastructure using a pay-as-go model.

Amazon Web Services (AWS) is the largest provider of cloud computing services today, followed by Microsoft and Google as per the Gartner 2023 Magic Quadrant for Strategic Cloud Platform Services. AWS offers over 200 services designed to help businesses of all sizes build, design, and deploy scalable, secure, and cost-effective solutions in the cloud. Furthermore, AWS offers access to its global data centers, enabling businesses to deploy their applications closer to their customers without the need to procure and provision infrastructure in those locations. Even small start-ups can access a global customer base and fulfill compliance and regulatory requirements.

This book will teach you all the skills necessary to pass the AWS Certified Developer Associate certification and excel at typical job roles such as cloud developer, junior DevOps engineer, cloud engineer, and many more. It covers AWS architecture design patterns following industry standard best practices and helps you build proficiency in developing, deploying, and debugging cloud-based applications on AWS. This book has also been designed to help you develop real-world practical skills from the ground up. This is achieved by incorporating a scenario throughout the chapters such that, as you learn new technologies and concepts, you also develop the skills to put that knowledge to practical use using the project exercises provided.

We will start by introducing the AWS Global Infrastructure, which represents the vast collection of data center facilities located across multiple countries throughout the world, which you can access to design, build, and deploy cloud resources. You will also learn about the various tools used to help effectively manage your AWS accounts. Furthermore, you will also complete a series of exercises that will help you to apply the principles related to having a multi-account AWS architecture in real-world use cases.
