Each service owns a specific business capability, runs in its own process, and communicates over lightweight protocols such as HTTP\/REST, gRPC, or asynchronous messaging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike a monolith \u2014 where all features live in one codebase and deploy as a single unit \u2014 microservices let teams ship, scale, and fail independently. Netflix, Amazon, and Uber popularized this style to handle massive scale and rapid feature delivery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Characteristics<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Single responsibility<\/strong> \u2014 each service does one thing well (orders, payments, inventory).<\/li>\n<li><strong>Independent deployment<\/strong> \u2014 deploy one service without redeploying the entire system.<\/li>\n<li><strong>Decentralized data<\/strong> \u2014 database-per-service; no shared tables across boundaries.<\/li>\n<li><strong>Polyglot persistence<\/strong> \u2014 choose the best database per service (PostgreSQL, MongoDB, Redis).<\/li>\n<li><strong>Resilience by design<\/strong> \u2014 failures are isolated; circuit breakers prevent cascading outages.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Microservices vs Monolith<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Start with a monolith when your team is small, domain is unclear, or speed of initial delivery matters most. Split into microservices when you hit scaling bottlenecks, need independent team ownership, or require different scaling profiles for read-heavy vs write-heavy components.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Core Building Blocks (2026)<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>API Gateway<\/strong> \u2014 single entry point for clients (Kong, Envoy, AWS API Gateway).<\/li>\n<li><strong>Service discovery<\/strong> \u2014 Kubernetes DNS, Consul, or Eureka.<\/li>\n<li><strong>Message broker<\/strong> \u2014 Apache Kafka for event-driven communication.<\/li>\n<li><strong>Container orchestration<\/strong> \u2014 Kubernetes for deployment, scaling, and health checks.<\/li>\n<li><strong>Observability<\/strong> \u2014 OpenTelemetry traces, Prometheus metrics, structured logging.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Example: E-Commerce System<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An online store might split into: <em>Product Catalog<\/em>, <em>Order Service<\/em>, <em>Payment Service<\/em>, <em>Inventory Service<\/em>, and <em>Notification Service<\/em>. When a customer places an order, the Order Service publishes an <code>OrderCreated<\/code> event. Payment and Inventory services react asynchronously \u2014 no direct database coupling.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Challenges to Planar<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Distributed transactions \u2014 use Saga pattern instead of two-phase commit.<\/li>\n<li>Eventual consistency \u2014 reads may lag behind writes; design UX accordingly.<\/li>\n<li>Operational complexity \u2014 more services means more monitoring and deployment pipelines.<\/li>\n<li>Network latency \u2014 prefer async events over chatty synchronous calls.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What to Learn Next<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Continue with <a href=\"\/microservices\/02-monolith-vs-microservices\/\">Monolith vs Microservices<\/a>, then explore <a href=\"\/microservices\/cqrs-pattern-microservices-kafka-2026\/\">CQRS with Kafka<\/a> and <a href=\"\/microservices\/deploy-microservices-kubernetes-production-checklist\/\">Kubernetes deployment<\/a>.<\/p>\n\n\n<h3 class=\"wp-block-heading\">Microservices Tutorial Series<\/h3>\n\n\n<ul class=\"wp-block-list\"><li><a href=\"\/microservices\/01-microservices-introduction\/\">1.
