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.

Storing application images on the OCI registry

The OCI registry is a highly available Docker v2 container registry service that provides either a private or public service for storing and sharing container images. It is a regional service, which means you have different endpoints for different regions. It is a fully managed service and Oracle doesn't charge you for it. You can use the Docker CLI to push and pull images from the registry, and you can also use Kubernetes to download the images and run them on a fully managed Kubernetes environment.

Developers need to store these container images on a registry to maintain their state. You can use free and open source registries as well, but there are issues with doing this, such as access rights. The OCI registry is fully integrated with OKE and runs on the same OCI backend infrastructure. The following diagram shows these two service's integration and the customer's responsibilities:
