Preface

With enterprises looking at more agile ways of delivering applications, cloud computing has become the standard way of delivering enterprise applications. Cloud computing, especially the public cloud, is a convenient way to access on-demand infrastructure, platforms, and software, at web scale. This is more convenient for enterprise companies because of their cost modeling as well. With the surge in cloud computing adoption, enterprise companies are cutting down on their capital investment, streamlining service desk operations, scaling up their business, and pushing the security and flexibility to a much higher level so that they can help their customers in different ways and achieve much higher business growth in this ever-changing global market.

When an enterprise deploys its application on a public cloud, predominantly, the public cloud provider owns the whole infrastructure, that is, the hardware, the software that manages the public cloud, and other supporting infrastructure. Enterprise companies access these exclusively over the internet.

Within cloud computing, Infrastructure as a Service (IaaS) is the building block of cloud-based IT. IaaS replaces the traditional IT infrastructure that is hosted in customers' on-premises environments. Traditionally, you will find that customers have physical servers that run both traditional operating systems and hypervisor, storage, and network infrastructures.

Oracle Cloud Infrastructure (OCI) is a set of complementary cloud services that enables you to build and run a wide range of applications and services in a highly available hosted environment. OCI offers high-performance compute capabilities (as physical hardware instances) and storage capacity in a flexible overlay virtual network that is securely accessible from your on-premises network.

In this book, you will find step-by-step explanations of key OCI concepts along with practical examples that demonstrate the key use cases of OCI's IaaS model. It follows a hands-on approach where each OCI service is followed by the steps you'd follow to implement it in your infrastructure. By the end of this book, you will have a solid understanding of OCI implementation and use cases.
