Build OCI applications that are designed for production-not just applications that happen to run in the cloud.
Moving an application to Oracle Cloud Infrastructure is easy to describe as a deployment exercise. Building a system that remains secure, reliable, observable, scalable, and recoverable under real production conditions is a very different challenge.
The Practical Oracle Cloud Engineer takes a practical, production-focused approach to engineering applications on OCI. Instead of treating cloud services as isolated features, this book shows how networking, identity, configuration, data, background processing, deployment, monitoring, and recovery fit together as one production system.
Using realistic engineering scenarios and hands-on coding examples, the book explores the problems that often appear after the first successful deployment:
- Why adding more compute can make a database bottleneck worse
- Why making a resource public is rarely a good solution to a connectivity problem
- How excessive IAM permissions create security and operational risk
- Why credentials should not follow an application into production
- When an HTTP request should become asynchronous background work
- How queues and workers change the failure model of an application
- Why a successful deployment does not necessarily mean a healthy release
- How to design systems that can be diagnosed and recovered during an incident
You will learn how to approach OCI from an engineer's perspective: define boundaries, understand dependencies, control access, make state manageable, move the right work out of the request path, and make deployments predictable.
The book also includes practical reference appendices for network design, IAM reviews, secret management, database and background-processing readiness, deployment and recovery, incident response, and production-readiness assessment.
What You Will Learn- Design production-oriented application architectures on OCI
- Build network boundaries around real application communication
- Apply IAM without resorting to excessive permissions
- Separate configuration from secrets and application code
- Identify and address database scalability bottlenecks
- Build reliable asynchronous workflows with queues and workers
- Design retry and failure-handling strategies
- Create deployment and rollback practices that developers can trust
- Use observability to determine whether a deployment is actually healthy
- Prepare applications for operational failures rather than only the happy path
Whether you are an application developer, cloud engineer, DevOps practitioner, software architect, or engineer moving workloads to OCI, The Practical Oracle Cloud Engineer provides a practical framework for thinking about the systems you build after "it works" is no longer good enough.
