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.

Connection choices

You need to connect to OCI resources in order to access them. Without a connection in place, you cannot connect to your workloads. You can connect to your OCI resources to and from OCI using three different methods:

  • Connecting through the public internet
  • Connecting through a VPN
  • Connecting through FastConnect

Let's discuss them in the next section.

Connecting through the public internet

Accessing an OCI instance over the public internet is pretty straightforward, and doesn't require much effort. You would need to go through the following steps to get internet access to and from the OCI instance:

  1. Create a VCN and provide a CIDR range.
  2. Create an internet gateway.
  3. Create a route rule with traffic to the internet gateway (for all IP addresses, 0.0.0.0/0).
  4. Create security list rules to allow traffic.
  5. Make sure that each instance's firewall allows the traffic as well.
  6. Create a public subnet within...
