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.

Deploying microservices on OKE

Before we deep dive into Oracle's managed Kubernetes offering, let's provide a short introduction to Kubernetes itself. Learning about Kubernetes is a huge topic. This chapter will not cover all the aspects of Kubernetes; it will only focus on the key concepts and how OCI's managed Kubernetes service works.

Getting started with Kubernetes

Kubernetes is an open source project that's maintained by a community of developers and was created to solve container orchestration problems. By its very nature, Kubernetes is highly available and forms a single cluster unit. Kubernetes allows you to deploy and run your application in the form of disjoined/distributed software services, without pinning it to run on a specific computer.

You can manage your cluster through a web UI or through a CLI (kubectl). A Kubernetes cluster has two types of resources, as follows:

  • A master node, which is responsible for managing the state of the...
