Training details

Description

As one of the SRE discipline founders puts it, Site Reliability Engineering is "what happens when you ask software engineers to manage IT infrastructure and operations". SRE involves applying proven software development techniques to operational tasks such as monitoring, deployment, and incident management.

An SRE approach aims to optimize both teams and the technical systems they operate. The goal is to enhance system evolution without compromising on reliability and availability requirements. This involves continuous health monitoring of systems, maximizing task automation, and ongoing team learning.

Through a mix of theoretical modules, revisiting the foundations of SRE, and practical work to apply concepts, this training offers participants a deeper understanding of the techniques, methods, and tools essential for implementing an SRE approach in their environment.

Objectives

• Learn the principles and practices of Site Reliability Engineering
• Identify different roles in an SRE team
• Learn to set performance and reliability goals, and define means to achieve them
• Monitor the reliability of your platform
• Facilitate dialogue with development/product teams through the management of a shared "error budget"
• Effectively handle incidents, turning them into improvement and learning opportunities

Target Audience

Anyone operationally involved or in a management position of a production IT system, including:

• Ops and System Administrators
• Information System Managers (COO, CTO, etc.)
• Developers
• Consultants
• Integrators
• Operators

Prerequisites

Understanding and knowledge of common DevOps terminology and concepts.

Pedagogical method

Training includes theoretical contributions, discussions on participants' contexts, practical experience feedback from trainers, supplemented with practical work and simulations.

• Proportion of presentations: 70%
• Proportion of practical cases: 20%
• Proportion of experience sharing: 10%

Evaluation and follow-up mode

Skill acquisition is evaluated throughout the session via workshops and practical applications. A post-training satisfaction survey is systematically conducted, and a training certificate is issued to participants, detailing the training objectives, nature, program, duration, and formalized learnings.
