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.

Chapter 3: Designing a Network on Oracle Cloud Infrastructure

Virtual Cloud Networks (VCNs) provide network connectivity to all of the OCI services with a fully customizable private network in the Oracle cloud. Customers can bring in their own IP segment and assign it to their VCN. They can create their own network topology using guided workflows to connect the virtual subnets with virtual routers and set up firewall rules. Optionally, the VCN can be configured to have internet access and/or VPN access. Customers can then launch bare metal or virtual machine instances in VCN subnets, and the instances will be assigned a private IP address from that same subnet. Optionally, the public IP address can also be assigned to an instance that will enable communication with the internet. Customers can also use security lists (groups of firewall rules) that can be associated with an instance. A VCN is regional and does not span multiple regions. A VCN can span across multiple Availability Domains...
