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.

VCN flow logs

VCN flow logs keep detailed records of every flow that passes through your VCN and present this data for analysis in the OCI Logging service. The data includes information about the source and destination of the traffic, along with the quantity of traffic and the permit or deny action taken, based on your network security rules. You can use this information for network monitoring, troubleshooting, and compliance. Through integration with the logging service, you can view, search, and retrieve log files.

Customers can use the service connector to create the object storage bucket and archive the data, as well as use the Oracle Streaming service to deliver the data to a third-party log analysis tool of their choice.

At a high level, the following steps show how flow logs will collect data:

  1. Flow logs will send data every minute to OCI Logging for VNICs.
  2. OCI Logging will index flow the log data every 10 mins and serve it to the customers.
  3. Data sent to...
