Scaling Applications: Performance Optimization with Copilot

As applications grow, slow database queries and unoptimized code can degrade the user experience and increase infrastructure costs. This text-based course helps you master modern scalability and performance optimization techniques to keep your systems running smoothly under heavy loads. You will transition from writing basic code to architecting fast, highly scalable systems, leveraging AI-powered assistants to identify bottlenecks and refactor code. What you'll learn: - Understand foundational scalability concepts, including vertical versus horizontal scaling and system bottlenecks. - Implement caching strategies using both in-memory and distributed caching patterns to reduce server load. - Optimize database queries and indexing structures to ensure rapid data retrieval. - Apply Copilot prompts to automatically analyze, refactor, and improve application code performance. - Configure load balancing and basic microservices architecture principles for high availability. - Monitor system health using modern observability and performance metrics. Starting with essential performance definitions and basic architectural concepts, this course guides you through written explanations, conceptual diagrams described in text, and practical code refactoring scenarios. This course is designed for beginner to intermediate developers looking to scale their applications, with no prior system design experience required. Start reading today to build faster, more resilient applications that scale effortlessly.
