The following are some of the common AWS services that are used in building Serverless applications on the AWS:

• AWS Lambda lets you write code without configuring any server.
• Amazon API Gateway lets you create REST APIs without coding.
• Amazon Simple Storage Service (S3) is an object store that helps you store and retrieve data. S3 can also be used for hosting single-page applications (SPA) such as an angular or react application.
• Amazon DynamoDB is a scalable NoSQL database.
• Amazon CloudFront is a Content Delivery Network (CDN) service.
• Amazon CloudWatch is a service to monitor your applications and respond to changes.
• AWS CloudFormation templates written in JSON or YAML can be used to provision and model our infrastructure. 
• AWS Identity and Access Management (IAM) provides access control for AWS resources.
• Amazon Cognito helps you build access control for your application with features such as user sign-up, sign-in, and more.
• Other services can be used alongside these services for advanced use cases, such as natural language processing (for example, Alexa Skills kit, and Lex), Analytics (Amazon Kinesis Streams), Machine Learning (Amazon Machine Learning), and so on. 

Apart from using the AWS management console from a browser, we can also interact with AWS services from AWS CLI (command line) and AWS SDK (programmatic access). Except for the first few recipes, we will mostly focus on using Amazon CloudWatch with AWS CLI for modeling and provisioning our infrastructure.
