A free, open source book to learn how to deliver cloud-native applications at high velocity.

Software developers lose focus and time by waiting for code changes to propagate through slow CI/CD pipelines. That goes unnoticed because everyone assumes it’s inevitable.

This whitepaper explains in detail:

- Why fast CI/CD is vital for your team
- A reality check to determine if your current process is fast enough
- What makes a productive CI/CD pipeline
- Real-world results & ROI with Semaphore

CI/CD enables the best tech companies to improve their products many times per day. Here’s what you need to know to do the same.

Continuous integration enables iterative software development, reduces risks from defects and makes developers highly productive.

Do you want your engineering team to deliver bug-free code at high velocity? A fast and reliable CI/CD pipeline is crucial for doing that sustainably over time.

Tired of fragile code? This free hands-on book will teach you how to build better Ruby on Rails apps with confidence. Learn practical behavior-driven development (BDD) from the makers of Semaphore.

In Rails Testing Handbook, you’ll learn about:

* How to get in the BDD mindset and apply it in practice;
* Setting up RSpec, Cucumber, database cleaner and others;
* Developing features from scratch in red - green - refactor cycles;
* Writing integration tests as Cucumber… Show more

Microservices solve productivity and production performance problems that typically arise with monoliths — and do that best when they are implemented to work asynchronously. The thing is, as Rails developers, we are used to thinking in terms of synchronous REST APIs. To scale up, we need to rewire our brains.

Behavior-driven development (BDD) is about minimizing the feedback loop. It is a logical step forward in the evolution of the practice of software development. This article explains the concept and its origins.
