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.

Authorization

You can define what privileges you need in policies and associate them with principals. OCI authorization works on the least privilege-first approach, so you are not allowed to perform any actions.

You can specify one or more policy statements in a human-readable format. These policy statements allow you to gain access to OCI resources and outline what you can do with them.

Let's take a look at a few human-readable policy statements:

Allow group <group_name> to <verb> <resource-type> in tenancy 
Allow group <group_name> to <verb> <resource-type> in compartment <compartment_name> [where <conditions>]

You can either attach these policies to a compartment or at the tenancy level.
