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 File Storage Service

The OCI FSS is an enterprise-grade network filesystem, and at the same time, it is durable, scalable, and secure as well. As it's a network file storage service, it utilizes the same VCN backbone to serve, so you can use any instance type, be it bare-metal or VM, or even containers as well. If you implement VCN peering or a FastConnect or Internet Protocol Security (IPsec) VPN, then you can even access the filesystem from outside of the host VCN.

It's so massively scalable that you can even connect thousands of compute instances to the filesystem. It uses the Network File System version 3.0 (NFS v3.0) protocol, and for the locking mechanism, it uses Network Lock Manager (NLM). For the best reliability, OCI uses five-way replication of the filesystem and stores it in different fault domains. For data protection, it uses snapshots; you can have 10,000 snapshots per filesystem. For security, it employs 128-bit data-at-rest encryption for all filesystems...
