A COMPREHENSIVE STUDY AND OVERVIEW OF CLOUD COMPUTING ARCHITECTURE

We often heard about cloud computing technology, benefits and related challenges specially related privacy and security, but not all really aware about how exactly cloud technology works and how security is still a big concern. Security is a big concern doesn’t mean there is no security exists in cloud computing, it’s all about to understand the gaps in existing implementations. One of the best approaches to understand the functionality of cloud computing and security gaps is, first understand the basic and high level architecture of cloud computing, and then how some of the leading cloud providers implemented the security functionalities. In this paper I am going to explain basic and high level architecture of cloud computing, and then overview of some of the leading cloud service providers cloud architecture like Amazon AWS and MS Azure
