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.

Understanding the use cases of ORM

Oracle provides a managed service of Terraform called ORM, which manages infrastructure using HashiCorp Terraform. It uses templates to define configurations, and you can reuse those templates as needed. It's a free service and you need to pay only for infrastructure, not for service. ORM is deeply integrated with OCI services, such as identity, security, metering, monitoring, and tagging.

Oracle built this ORM service on unmodified open source software, meaning there is no lock-in and you get simple migrations from or to any private and third-party clouds. Here, you can see a high-level diagram of the ORM stack. This workflow depicts how you can use ORM to deploy a web application to different environments on OCI:

Here are the benefits of using ORM:

  • As with Terraform, you can use ORM to unlock infrastructure automation capabilities that can help you to standardize your...
