Practical Oracle Cloud Infrastructure refers to the hands-on approach to understanding and utilizing Oracle’s Cloud Infrastructure (OCI) services. Oracle Cloud Infrastructure is a set of cloud services that enable you to build and manage a wide range of applications, from simple websites to complex, mission-critical applications. It offers services like Compute, Storage, Networking, Databases, Analytics, and various other resources that you can use to deploy, manage, and scale your applications.

A “practical” approach usually involves:

1. Learning the Basics: Understanding the fundamental concepts such as virtual cloud networks, compute instances, and object storage.

2. Hands-On Labs: Actual implementation or lab work where you try to build or configure resources on OCI.

3. Real-world Scenarios: Simulating or actually building architectures that solve real-world problems, often based on case studies or business requirements.

4. Cost Management: Learning how to estimate and manage costs effectively in a cloud environment.

5. Security: Implementing security best practices like Identity and Access Management (IAM), firewall settings, etc.

6. Automation and DevOps: Using tools and services like Terraform or Oracle’s own Resource Manager for infrastructure as code, and understanding CI/CD implementations in OCI.

7. Monitoring and Management: Learning how to monitor resources, interpret logs, and perform routine management tasks.

Books, online courses, tutorials, and workshops focused on “Practical Oracle Cloud Infrastructure” will typically cover these aspects to provide a well-rounded skill set for managing applications and services on OCI.
