Replicate Databases for High Availability

Overview

Did you know that unplanned database downtime costs businesses an average of $9,000 per minute? Configuring replication ensures your systems stay online, your data stays safe, and your users stay connected. This Short Course was created to help professionals in this field implement reliable database architectures that ensure continuous data availability and prevent system failures from impacting critical business operations. By completing this course, you will be able to configure database replication to maintain high availability and optimize performance through read replicas, building resilient systems that keep essential services running smoothly. By the end of this 3-hour long course, you will be able to: Configure database replication to ensure high availability for read replicas. This course is unique because it blends practical replication setup with real-world reliability strategies, helping you create fault-tolerant database environments that safeguard uptime and enhance scalability. To be successful in this project, you should have: Basic database administration knowledge Understanding of SQL concepts Familiarity with PostgreSQL or similar RDBMS Command-line interface experience

Syllabus

Module 1: Database Replication Fundamentals

Learners will understand the critical importance of database replication for high availability, explore fundamental concepts of streaming replication and physical replication slots, and gain foundational knowledge needed for implementing fault-tolerant database architectures.

Module 2: Implementation & Monitoring

Learners will implement complete streaming replica configuration, validate replication health through monitoring, and demonstrate mastery by configuring a production-ready high availability setup with sub-5-second lag performance.
