Microservices

Introduction In today’s interconnected digital landscape, APIs (Application Programming Interfaces) serve as the backbone of modern software development, enabling seamless communication between disparate systems. However, managing and securing APIs can be complex, especially in microservices architectures where numerous services interact with each other. What is an API Gateway? An API gateway is an architectural pattern that sits between clients and backend services, acting as a single entry point for all incoming API requests. It serves as a reverse proxy, routing requests to the appropriate services based on predefined rules and configurations. API gateways offer a centralized point of control for managing various aspects of API communication, including routing, authentication, authorization, rate limiting, logging, and monitoring. ...

Introduction In distributed systems, maintaining data consistency across multiple systems is a challenging task. One common problem that arises is the dual write problem, where updates to multiple data stores must be performed atomically to prevent data inconsistencies. In this blog post, we’ll explore how to tackle the dual write problem using the outbox pattern in conjunction with Apache Kafka. Understanding the Dual Write Problem The dual write problem occurs when data needs to be written to multiple systems, and ensuring consistency between them becomes crucial. For instance, imagine an e-commerce application where an order is placed and data must be simultaneously written to a database and a messaging system like Kafka for further processing. If one write succeeds but the other fails, data inconsistency arises. ...
