Elemento Cloud introduces the C4 protocol, a groundbreaking framework designed to revolutionize the cloud computing landscape. Drawing inspiration from the success of the S3 protocol for cloud storage, C4 combines the strengths of TCP and UDP to facilitate seamless resource allocation and management across distributed systems. This whitepaper delves deeper into the C4 protocol, focusing on its support for diverse computing resources, including CPU architectures, GPUs, accelerators, and specialized memory configurations, while also highlighting its vision for interoperability, seamless integration across cloud providers and private servers, and making cloud computing a universally accessible commodity.

## Introduction

### Background

C4's pledge representation encompasses memory configurations, allowing clients to specify persistent and error-correcting memory options. This includes support for technologies such as non-volatile dual in-line memory modules (NVDIMM), error-correcting code (ECC) RAM, and other specialized memory architectures. By offering tailored memory configurations, C4 ensures compatibility and seamless integration with diverse computing environments, enabling enhanced performance, reliability, and data integrity for cloud-based applications and services.

## Protocol Components

### TCP+UDP API
