Résumé
You'll start by reviewing key AWS prerequisite services such as EC2, Lambda, S3, DynamoDB, CloudWatch, and IAM. Simple Queue Service (SQS) and SNS Simple Notification Service (SNS) are then covered to show how applications interact with each other in a reliable and resilient fashion. Next, workflow building with (Simple Workflow Service (SWF) for orchestration of tasks is explained and in the final chapter learn the techniques for building a state using Step Functions, Simple Workflow Service along with Flow Framework.
The book illustrates all the concepts using numerous examples that work with SDK, CLI, and Console. Most of the code examples are in Java, followed by Python and JavaScript.
What You Will Learn
- Understand the important prerequisites of AWS, such as EC2, Lambda, S3, and DynamoDB
- Work with SQS, SNS, and SWS functions

AWS developers and software developers proficient in Java, Python and JavaScript.
No of pages 25
Sub -Topics1. Introduce all the prerequisites like DynamoDB, Lambda, IAM, S3
2. Guide through the creation of AWS free account and set up IAM roles
3. Create a static website using S3
4. Introduce DynamoDB through Lambda and API Gateway
Chapter 2: Simple Queue ServiceChapter Goal: This chapter teaches the reader how to use SQS to pass messages between two separate services. This covers both ends of publishing a message as well as polling for messages. The chapter also introduces FIFO Queues and how to use them. This takes the knowledge further by teaching how to use retries and DLQ in a production environment to build fault-tolerant applications.

Sub - Topics
1. Sending messages between distributed applications2. FIFO and Dead Letter Queues
3. Long Polling and Deduplication
4. Using Server-Side Encryption, Visibility, Timeouts, Delays
5. Lambda Triggers and Batch Actions
Chapter 3: Simple Notification Service
Chapter Goal: This chapter focuses on Simple Notification Service, another service to pass messages across different parts of an application. Along with introducing key concepts of SNS, this also lays a foundation on how to send messages from SNS to SQS, how to send SMS messages or Push Notifications. This chapter also explains various actions such as Creating Topic and Publish that can be performed through API.

Sub - Topics:1. Topic, Endpoint and Subscription configuration
2. Publishing messages to an SNS topic
3. Interoperability between SQS and SNS
4. API and CLI
Chapter 4: Simple Workflow Service
Chapter Goal: This chapter takes the coordination of services a little further by introducing another service named SWF. The reader will be able to understand how to build workflows and attach the services created like Lambda functions, applications running on EC2 etc., This chapter introduces both AWS SDKs as well as Flow Framework which is an enhanced SDK meant for developing distributed applications that use SWF.

4. Flow Framework
5. HTTP Service API
6. API and CLI
Chapter 5: Step Functions
Chapter Goal: This chapter starts off by quickly describing key concepts of AWS Step Functions and provides practical instructions for using the features of AWS Step Functions. It further delves into Amazon State Language and shows how to define your State Machine and processing of Inputs, Outputs, and Error Handling. This chapter is wrapped up by how the same can be achieved using SDKs and HTTP APIs and explaining several best practices of using Step Functions.
