Welcome2:04
Explore the 12 factor app principles to build scalable, maintainable cloud-native applications. Learn to organize code, manage dependencies, deploy across cloud environments, and monitor with effective logs.
Preface3:16
Introduction to 12 Factor App Methodology4:21
Explore the 12 factor app methodology and its principles for modern microservice based cloud native web applications across languages, emphasizing declarative setup, automation, portability, and continuous deployment.

Background3:59
Explore how cloud native design, elastic scalability, statelessness, and treating everything as a service guide building scalable, automation-ready applications, and learn the origins and purpose of the 12 factors.
Why 12 Factor App?1:52
The 12 factor app methodology helps you release code quickly, scale efficiently, and maintain it. It uses declarative setup automation and cloud deployment with no servers.
Business Benefits1:54
Discover how the 12-factor methodology enables robust, scalable web apps through continuous deployment, delivering elasticity, modularity, and secure environment-based credentials for business benefits.
Who should use 12 Factor App?1:43
Identify software developers building saas, cloud apps, distributed software, and microservices as users of the 12 factor app methodology. Guide robust, automated cloud architecture and timely feature releases.

Codebase3:05
Explain the code base as the single repository tied to an app in version control, ensuring one code base per app across all deploys, from local development to production.
Dependencies3:25
Config4:22
Backing Services4:07
Treat databases, storage, queues, and APIs as attached resources, enabling seamless swapping between local and third-party services (like MySQL to RDS or SMTP to Postmark) without code changes.
Build Release Run2:50
Explore the build, release, and run stages and their strict separation. Learn to assign unique release IDs, maintain an append-only ledger, and roll back safely across environments.
Processes3:15
Explore the 12 factor processes principle, highlighting stateless, share-nothing apps that rely on backing services for data and reject sticky sessions for scalable, portable, resilient deployments.
Port Binding2:44
Bind the application to a specific port to export HTTP as a service, providing a defined entry point for requests, enabling modular, scalable, self-contained 12 factor apps.
Concurrency2:58
Explore concurrency by structuring apps as independent processes: web, worker, and background, scale out with process formation, and balance workloads through horizontal scaling and functions as a service.
Disposability2:43
Dev Prod Parity3:36
Shrink the time, personnel, and tools gaps to achieve dev prod parity. Keep development and production backing services the same to support continuous deployment.
Logs2:45
Admin Process2:50

What lies beyond 12 Factor App2:22
FAQs2:28
Explore common FAQs about the 12 factor app methodology, including why to separate configuration from code, and how the model ensures fast startup, graceful shutdown, and robustness for cloud-native SaaS.
Next Steps4:19
Explore essential 12 factor app resources, including 12factor.net and Heroku’s guide, plus cloud-first microservices demos on Google Cloud and Open Liberty–Quarkus examples for practical learning.
Thankyou2:02
Explore the 12 factor app principles to design and deploy scalable modern web apps. Apply configuration management, dev to prod transitions, and robust logging for reliable operations.

Description

Understanding how to design systems to run in the cloud has never been more important than it is today. Cloud computing is rapidly transitioning from a niche technology embraced by startups and tech-forward companies to the foundation upon which enterprise systems build their future. In order to compete in today’s market‐place, organizations large and small are embracing cloud architectures and practices.

Here, Developers are often left with many questions about the disciplines and practices they should adopt to build applications designed to take advantage of everything the cloud offers. This course around the Twelve-Factor App answers those questions and more.

The Twelve-Factor Application is one of these phrases that is gaining traction and is being passed around during planning meetings, discussions over coffee, and architecture review sessions. The problem with shared context and common language like buzz‐words is that not everyone has the same understanding. Twelve Factor to one person might mean something entirely different to someone else, and many viewers of this course might not have any exposure to the 12 factors.

So The goal of this course is to provide detail on what exactly TwelveFactor applications are so that hopefully everyone who has takes the course shares the same understanding of the factors. Additionally, this course aims to take you beyond the 12 factors, expanding on the original guidelines to accommodate modern thinking on building applications that don’t just function in the cloud, but thrive.

See you inside !
