Oracle Cloud Infrastructure for Solutions Architects

By: Prasenjit Sarkar

Overview of this book

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. This book is a fast-paced practical guide that will help you develop the capabilities to leverage OCI services and effectively manage your cloud infrastructure. Oracle Cloud Infrastructure for Solutions Architects begins by helping you get to grips with the fundamentals of Oracle Cloud Infrastructure, and moves on to cover the building blocks of the layers of Infrastructure as a Service (IaaS), such as Identity and Access Management (IAM), compute, storage, network, and database. As you advance, you’ll delve into the development aspects of OCI, where you’ll learn to build cloud-native applications and perform operations on OCI resources as well as use the CLI, API, and SDK. Finally, you’ll explore the capabilities of building an Oracle hybrid cloud infrastructure. By the end of this book, you’ll have learned how to leverage the OCI and gained a solid understanding of the persona of an architect as well as a developer’s perspective.

Introducing the different OCI compute instance types

OCI is the only public cloud that supports bare metal and VMs using the same set of APIs, hardware, firmware, software stack, and networking infrastructure. You can see the two models in the following diagram:

Bare metal instances are instances where customers get the full server. This is also referred to as a single-tenant model. The advantage here is that there is no performance overhead, no shared agents, and no noisy neighbors. For performance and isolation requirements, this is the best instance type. You can see an example of this in the following diagram:

On the other spectrum is virtual machines (VMs), where the underlying host is virtualized to provide smaller VMs. This is also referred to as a multi-tenant model. The advantage here is flexibility in regard to what instance...
