Today, we’re diving deep into DDG Search Store – an elegant FastAPI-based solution that lets you search DuckDuckGo, store results, and manage them through a Read more
The Backend for Frontend (BFF) pattern creates dedicated backend services tailored to specific frontend needs, avoiding bloated generic APIs. It improves performance by aggregating and optimizing data from microservices for clients like web or mobile apps. This approach draws from microservices evolution, popularized by Sam Newman around 2015. BFF Pattern Read more
The Circuit Breaker pattern acts as a safety mechanism in distributed systems, preventing cascading failures when external services become unresponsive. Inspired by electrical circuit breakers, it monitors call success rates and “trips” to an OPEN state when failures exceed thresholds, blocking further calls to protect the calling service. This solves Read more
Implementing the Saga pattern in Spring Boot microservices involves coordinating local transactions across services using events, with compensating actions for failures, as shown in a banking funds transfer scenario behind Kong Gateway. This approach ensures eventual consistency in distributed systems without two-phase commit. Banking Scenario: Funds Transfer Saga In a Read more
In the evolving landscape of microservices architecture, the API Gateway pattern stands as a cornerstone for managing complexity, enhancing security, and optimizing performance. This single-entry-point facade simplifies how clients—whether mobile apps, web frontends, or third-party integrations—interact with a sprawling ecosystem of backend microservices. By decoupling external consumers from internal service details, the API Gateway enables seamless Read more
In a microservices architecture, the database-per-service pattern means each microservice owns its own private database instead of sharing a single central DB. Other services can only access that data through the service’s API, never by querying its tables or collections directly. This pattern gives you: In this post, you will build a Read more
Creating efficient, scalable APIs is essential for modern applications. In this blog post, we’ll walk through building two separate CRUD APIs following the Command Query Responsibility Segregation (CQRS) pattern using Python’s FastAPI framework. We’ll use MongoDB as our document database to persist data. This tutorial includes detailed setup instructions, complete Read more
