The blog post series explores six architectural styles in distributed systems, focusing on Edge computing, which moves computation and data storage closer to end users to enhance speed, availability, and data processing. Edge computing differs from traditional cloud models by decentralizing data centers, thereby reducing bandwidth and response times. It features a layered system, with data replicated across cloud data centers, edge data centers, and devices, though challenges include limited computational resources, data security issues, and complex debugging. Despite these weaknesses, the architecture offers significant advantages such as high availability and data privacy by keeping sensitive data local, making it ideal for real-time applications like IoT, autonomous vehicles, and immersive technologies. The post also highlights a shift in the perceived primary benefits of edge computing from speed to consistency, cost, ease of use, and compliance.
