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.

Creating similar instances using instance configuration and instance pools

If you want to create a template configuration that will be used to create multiple OCI instances, then instance configuration is your friend. It is a template for configuration that we can use to create similar OCI instances. You can specify configuration for which OS image to choose, different shapes and their resource allocation, different block volume sizes, and so on.

These templates can be created using an existing OCI instance or using the OCI CLI. When you launch an instance using this instance configuration, OCI creates the resources that are defined within that template config.

You can see a logical representation of this in the following diagram:

OCI uses this instance configuration to create and manage identical instances in a logical group. This is known as an instance pool. The main use case for an instance pool is...
