From QA to Dev'QA'Ops
This document discusses the importance of testing infrastructure as code. It provides examples of organizations with and without infrastructure as code (IAC) to show the benefits of IAC. These benefits include faster deployment times, increased agility, higher quality, and less downtime. The document outlines different aspects of infrastructure that should be tested, including servers, services, networks, databases, deployments, hybrid environments, access control, and monitoring. It presents an ideal test pyramid with more unit and integration tests than acceptance tests. The goal is to shift infrastructure testing left to catch errors earlier. Overall, the document argues that testing infrastructure as code leads to more reliable deployments and better organizational performance.

- 6. IN A NUTSHELL… 6 ➢ Faster time to market ➢ Increased organizational agility ➢ Higher quality
- 7. WHY DO WE NEED TO TEST OUR INFRASTRUCTURE? ➢ High confidence in changes ➢ Quick and immediate feedback ➢ Shorter release cycle for applications ➢ Maintain sanity of the infrastructure 7

- 9. WHAT DO WE NEED TO TEST?? 9
- 10. CASE STUDY REQUIREMENTS ➢ Customer is able to visit the site and browse the products available. ➢ The website should be available 24*7 and should be able to sustain high traffic. ➢ Products should not be accessible before the launch date. ➢ We want to launch new features on a regular basis. ➢ The administrators should have detailed knowledge of the health of the system and issues should be resolvable quickly. 10
