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.

Discussing OCI database choices

Earlier, you learned that OCI databases predominately come in three different options. These database systems are protected by two- or three-way mirroring. In two-way mirroring, all the data gets mirrored, which means there are two copies of the same data. In three-way mirroring, you get additional protection from a bad disk sector in one disk and the failure of another disk. The database systems can be brought up as standalone or in a RAC cluster that is entirely configured and managed by the database service. In addition to RAC, Exadata systems are also available.

Because the systems are fully managed, they are Maximum Availability Architecture (MAA)-compliant.

Dynamic central processing unit (CPU) and storage scaling features are available, as well as the ability to upsize Exadata deployments across shapes. CPU core usage can be changed hourly to right-size the database system.

For security, there are several features and capabilities. These...
