Amazon Web Services (AWS) is one of the most popular and efficient cloud platforms for administering and deploying your applications to make them resilient and robust. AWS for System Administrators will help you to learn several advanced cloud administration concepts for deploying, managing, and operating highly available systems on AWS.

As you make your way through the chapters, you’ll get to grips with VPC, EC2, load balancer, Auto Scaling, RDS database, and data management. The book will also show you how to initiate AWS automated backups and store and keep track of log files. Later, you’ll work with AWS APIs and understand how to use them along with CloudFormation, Python Boto3 Script, and Terraform to automate infrastructure. By the end of this AWS book, you’ll be ready to build your two-tier startup with all the necessary infrastructure, monitoring, and logging components in place.

AWS RDS is a portfolio of managed relational database services that AWS offers to its customers. AWS provides a range of options, from commercial databases (for example, Oracle and Microsoft SQL Server) created by other vendors to the most popular open source database types (MySQL, MariaDB, and PostgreSQL). AWS also owns a cloud-native engine (Amazon Aurora), which is MySQL- and PostgreSQL-compatible. Using AWS RDS, you can manage these databases from one centralized console, the AWS CLI, or via API calls. Using this managed service has other advantages, such as the fact that all the administrative tasks including setting up the database, backups, and patching are already automated. There are a variety of use cases for AWS RDS:

  • Mobile and web application: It provides high availability and scalability for enterprise applications.
  • E-commerce applications: It provides the security and PCI compliance needed for e-commerce websites...
