The blog post discusses the Peer-to-Peer (P2P) computing architectural style, highlighting its decentralized nature, where nodes act both as clients and servers, facilitating direct communication and resource sharing without a central server. P2P has historical roots and gained public attention with file-sharing platforms like Napster, playing a significant role in network neutrality debates. While it enhances scalability, resilience, and fault tolerance, it also introduces complexities in network management, security, and observability due to its decentralized nature. P2P architecture is widely used in content distribution, VoIP, blockchain, and distributed machine learning. Despite its challenges, particularly in legal and ethical domains, P2P remains crucial for scalable distributed systems, especially in edge computing applications.
