In this book, you will learn how to build a fault-tolerant, scalable, and secure stack on AWS. You will also incorporate ease of deployment. Fault tolerance is avoiding downtime, and avoiding data loss when something fails. Scalability is ensuring the same performance at higher loads by adding more capacity. At the same time, it is important to reduce capacity when load decreases, this to help lower costs. Security is protecting content and data from unauthorized access. Ease of deployment is the ability to easily and frequently update applications. You will implement a complete architecture using AWS compute services - Elastic Cloud Compute (EC2) and Elastic Beanstalk, AWS storage services - Elastic Block Store (EBS) and Simple Storage Service (S3), AWS database services - Relational Database Service (RDS), ElastiCache and DynamoDB, AWS network services - Virtual Private Cloud (VPC) and CloudFront and Identity and Access Management (IAM), a security service.
