Site Reliability Engineering

Group Training + View more dates & times


The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems?

In this course, you will learn how and why the DevOps commitment to the entire lifecycle can enable the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization.

Who Should Take This Course


This course is suitable for DevOps, Admins, Developers, and Managers.


Students should have an IT background as a prerequisite for this course.


3-4 Days

Technical Requirements

Students will need a reasonably modern laptop with unrestricted connection to the Internet and Chrome browser. Laptops with overly restrictive VPNs or firewalls may not work properly. Cloud based lab environment will be provided to students, no local installations needed.
