Well it has really been a wonderful journey writing this book! You started off with learning the basics of Cloud Computing and slowly, but gradually, covered so much. From compute (EC2) to networks (VPC) to storage (S3), identity and access management (IAM), databases (RDS), DNS (Route53), and content delivery services (CloudFront).

Although this book may seem a lot to read and grasp, trust me, this is all just a drop in the ocean. AWS is a rapidly expanding and highly innovative public cloud that, if used correctly, can bring your business and organization a lot of benefits such as scalability, flexibility, and cost savings. The principle, however, remains the same— plan out your way before you start, make sure you have designed for failure, and continuously monitor and automate your infrastructure. Remember these and you should be just fine!
