Frequently Asked Questions

Site Reliability Engineering (SRE) is an engineering discipline that applies software engineering principles to infrastructure and operations. SRE engineers define Service Level Objectives (SLOs), manage error budgets, respond to incidents, build observability into systems, and automate operational work. The goal is to make production systems reliable, scalable, and maintainable at scale. SRE was originated at Google and is now practiced at thousands of technology-driven organizations worldwide.

If you are new to SRE or transitioning from DevOps, start with the Certified Site Reliability Engineer (CSRE) — it covers SRE fundamentals including SLOs, observability, incident management, and automation. If you already work in an SRE or reliability role and want to go deeper, the Certified Site Reliability Professional (CSRP) is the right next step. For architects and senior engineers, start with the CSRA. For managers and team leads, start with the CSRM.

DevOps is a culture and philosophy focused on collaboration between development and operations teams, emphasizing CI/CD, automation, and faster software delivery. SRE is a specific implementation of that philosophy that applies software engineering to operations. Where DevOps is broad and cultural, SRE is specific and technical — it defines concrete practices like SLOs, error budgets, toil reduction, and reliability engineering. SRE engineers typically have deeper reliability, observability, and incident management skills than generalist DevOps engineers.

SRESchool certification programs are for DevOps Engineers, Cloud Engineers, Platform Engineers, Operations Engineers, Software Engineers expanding into reliability work, Engineering Managers building SRE teams, and Architects designing reliable systems. We have certifications for every experience level — from engineers just starting their SRE journey to senior architects and managers leading reliability programs at scale.

Yes. We design and deliver customized SRE training programs for engineering teams of all sizes. Corporate training includes a custom syllabus built around your team's stack and goals, private instructor-led delivery (virtual or on-site), hands-on labs, and a certification pathway. Teams of 5 to 500+ are welcome. Contact us to discuss your requirements.

Yes. All SRESchool training courses are available as instructor-led virtual sessions delivered online — accessible from anywhere in the world. We also offer on-site delivery for corporate clients who prefer in-person training.

Absolutely. The Certified Site Reliability Engineer (CSRE) is one of the most valuable certifications a DevOps Engineer can earn. It teaches SLOs, error budgets, observability, incident management, and reliability engineering — skills that are increasingly required in DevOps roles and are the foundation of moving into an SRE career. Many DevOps Engineers use SRE certification to demonstrate deeper reliability engineering knowledge to employers.

You can enroll by contacting us via the contact form on our website, by emailing contact@sreschool.com, or by calling us directly at +91 99057 40781 (India) or +1 (469) 756-6329 (USA). Our team will help you choose the right certification or course for your role and experience level, provide batch dates, and guide you through the enrollment process.

SRESchool offers four certification programs in a progressive path: Certified Site Reliability Engineer (CSRE) at Foundation level, Certified Site Reliability Professional (CSRP) at Intermediate level, Certified Site Reliability Architect (CSRA) at Advanced level, and Certified Site Reliability Manager (CSRM) at Leadership level. You can start at any level that matches your experience.

You do not need to complete them in strict order. You can start with the certification that matches your current role and experience level. However, we recommend starting with CSRE if you are new to SRE, as it provides the foundation for all higher-level programs.

Each SRESchool certification includes: completion of the associated 5-day training course, hands-on labs and practical exercises, a certification exam, and an official SRESchool certification upon passing. Contact us for specific details on exam format and passing criteria.

SRESchool certifications are industry-focused programs designed around global SRE practices. They validate your SRE competency and are recognized by organizations worldwide as demonstrating structured, practical SRE knowledge.

All SRESchool training courses are 5-day programs delivered as intensive instructor-led training. Each day covers a major SRE topic with theory, practical examples, and hands-on labs.

Our training courses are available as live virtual instructor-led sessions (accessible from anywhere in the world), and as on-site instructor-led sessions for corporate clients. Private batches are available for teams of 5 or more.

Yes. For corporate and enterprise clients, we customize the course content to match your team's technology stack, maturity level, and specific learning goals. Contact us to discuss your customization requirements.

For the Foundation (SRE Engineer) course, you need basic Linux and cloud computing familiarity — no SRE experience required. For Intermediate and Advanced courses, prior SRE experience or completion of the Foundation course is recommended. See individual course pages for specific prerequisites.
