Web2 Infrastructure

Definition ∞ Web2 infrastructure refers to the centralized technological foundations that support the current generation of internet applications and services. This includes traditional cloud computing platforms, centralized databases, and server architectures managed by single entities. These systems contrast with decentralized Web3 models by relying on intermediaries for data storage, processing, and application delivery. It forms the backbone of most internet services today.
Context ∞ News in the crypto and blockchain space often contrasts Web2 infrastructure with the emerging Web3 paradigm, highlighting the limitations of centralization regarding data ownership, privacy, and censorship resistance. Discussions frequently address efforts to migrate applications from Web2 to Web3 or to integrate decentralized solutions with existing Web2 systems. Understanding Web2 infrastructure provides a baseline for appreciating the innovations and challenges presented by blockchain-based alternatives.
