16. AWS Cloud9
• Cloud-based integrated development environment (IDE)
• Let’s you write, run, and debug your code with just a
browser
• Share your environment with your team to pair program in
real time
• Direct terminal access to AWS
• Provides great serverless experience: enables local
testing and preconfigures the development environment
with all SDKs, libraries, and plugins

17. AWS Cloud9 Demo

18. AWS CDK
• Open-source framework to define cloud infrastructure in
TypeScript/JS/Python/Java/C#
• Provides library of higher-level resource types (“construct”
classes) that haveAWS best practices built in by default,
packaged as npm modules
• Provisions resources with CloudFormation
• Supports all CloudFormation resource types

21. AWS Elastic Beanstalk
• Preconfigured infrastructure:
• Single-instance (dev, low cost)
• Load-balanced, Auto Scaling (production)
• Web and worker tiers
• Elastic Beanstalk provisions necessary
infrastructure resources, such as the
load balancer, Auto Scaling group,
security groups, database (optional), etc.
• Provides a unique domain name for your
application
(e.g., yourapp.elasticbeanstalk.com)

24. Amazon CodeGuru
• CodeGuru leverages machine learning models and best practices informed by
years of experience and data from Amazon.com and AWS to find wide ranging
issues in source code such as use of un-sanitized inputs, inappropriate handling
of sensitive data, thread safety issues, and deviation from AWS best practices.
• CodeGuru includes:
 Automated code reviews with intelligent recommendations that even junior
staff can follow
 Code reviews seamlessly integrate with pull request workflow or performed
anytime on-demand
 Detection and optimization of the most expensive line of code
 Immediate identification of application inefficiencies running in a production
