The Advanced Developing on AWS course uses the real-world scenario of taking a legacy, on-premises monolithic application and refactoring it into a serverless microservices architecture. This three-day advanced course covers advanced development topics such as architecting for a cloud-native environment; deconstructing on-premises, legacy applications and repackaging them into cloud-based, cloud native architectures; and applying the tenets of the Twelve-Factor Application methodology.

• Course level: Advanced
• Duration: 3 days

Activities

This course includes presentations, group exercises, and hands-on labs.

Course objectives

In this course, you will:

• Analyze a monolithic application architecture to determine logical or programmatic break points where the application can be broken up across different AWS services
• Apply Twelve-Factor Application manifesto concepts and steps while migrating from a monolithic architecture
• Recommend the appropriate AWS services to develop a microservices based cloud-native application
• Use the AWS API, CLI, and SDKs to monitor and manage AWS services
• Migrate a monolithic application to a microservices application using the 6 Rs of migration
• Explain the SysOps and DevOps interdependencies necessary to deploy a microservices application in AWS

Intended Audience

This course is intended for experienced software developers who are already familiar with AWS services.

Prerequisites

We recommend that attendees of this course have:

• In-depth knowledge of at least one high-level programming language
• Working knowledge of core AWS services and public cloud implementation
• Completion of the Developing on AWS classroom training, and then a minimum of 6 months of application of those concepts in a real world environment
