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.

OCI Block Volume

To understand the service, let's begin by understanding what a block volume is. A block volume is a type of block device that is used as data storage. The OCI Block Volume service uses Internet Small Computer Systems Interface (iSCSI) to deliver features and performance. OCI Block Volume has been carefully designed for the security and durability of data and lets you create block volumes and attach them to your compute instance. The OCI Block Volume service delivers a simple, scalable block volume service that fulfills all your workload performance needs. You can treat this volume as your regular hard drive once you attach it to an instance. The Block Volume service utilizes industry-leading highest performance Non-Volatile Memory Express (NVMe) drives and is offered over the network using the standard iSCSI protocol.

The Block Volume service serves both the boot volume (for the operating system (OS) disk) and the block volume (applications data)...
