Architecting Secure, Scalable Web Services with REST and HTTP Principles

            <p>Modern products live or die by the quality of their web services. This course dives into architecting secure, scalable web services grounded in REST and the HTTP fundamentals you actually use day to day. You’ll learn how to think in resources and representations, design APIs that are easy to evolve, and apply HTTP correctly—methods, status codes, headers, content negotiation, and caching—so your services stay fast and predictable under real-world load. The goal is simple: help you design services that are secure by default, scale without drama, and remain maintainable long after version 1 ships.</p>

<p>We’ll start with the big picture—what a web service is, how it differs from websites and APIs, and why REST remains a practical default. From there, you’ll model resources cleanly, choose smart versioning strategies, and craft requests that scale with solid pagination, filtering, and error patterns like problem+json. You’ll harden your services with modern auth (OAuth 2.1, OIDC, tokens, scopes), secure headers, input validation, rate limiting, and safe logging practices. Performance gets real attention: HTTP caching, CDNs, compression, payload shaping, and avoiding N+1s—plus SLOs and p95/p99 thinking. For reliability, you’ll implement timeouts, retries with backoff and jitter, circuit breakers, bulkheads, load shedding, and idempotency keys.</p>

<p>As your system grows, you’ll learn when to split services, how to manage data ownership without distributed transaction nightmares, and when to pick sync REST, webhooks, or async messaging. We’ll cover event-driven patterns (pub/sub, queues, outbox), schema evolution, and building integration contracts that won’t break consumers. On the build-and-ship side, you’ll apply hexagonal architecture, keep code clean with validation and error middleware, model data with the right indexes and migrations, and wire in observability with structured logs, metrics, traces, and correlation IDs. Finally, you’ll move from local to prod with fewer surprises using OpenAPI and JSON Schema, layered testing (unit, contract, integration, chaos), progressive delivery (canary, blue/green), and solid operations practices—dashboards, alerting, runbooks, and incident response.</p>

<p>Short quizzes help you check your fundamentals on REST/HTTP, security, and resilience. By the end, you’ll have a practical toolkit for designing web services that are straightforward to build, safe to expose, and resilient at scale—without over-engineering. If you’re ready to level up your API craft and ship with confidence, this course has your back.</p>
