Many companies are considering taking to the cloud. However, before they can make this move, they need to determine what is the correct cloud service model to follow: (1) software as a service (SaaS), (2) platform as a service (PaaS), or (3) infrastructure as a service (IaaS). This book will guide corporations through some key design considerations.  It discusses the pros and cons of each cloud service model and highlights major design considerations in areas such as security, data storage, monitoring, APIs, and more.  It arms the reader with enough information to choose the right cloud service provider.  In addition, this book clearly defines what services the cloud providers offer for each service model and what cloud services IT must provide.
