SRE Foundation

SRE Foundation

About

The Site Reliability Engineering Foundation course will help you to learn the principles & practices that allows an organization to reliably and economically scale critical services. SRE is a process of operations which emphasize to accumulate software engineering and automation solutions to ensure that continuously delivered applications are running efficiently and reliably. Our course highlights the progression of SRE in the modern software engineering process and its future direction and prepares learners with the methods, practices, and tools to engage the workforce across the organization involved in reliability and stability evidenced through the use of real-life scenarios and case studies.

Prerequisite:

  • 6 months of working knowledge in cloud or DevOps
  • Linux fundamentals
