- You will build the skill to recommend a suitable cloud deployment model based on security, compliance, and performance needs.
- You will build the skill to explain foundational architectural decisions using concepts like scalability, elasticity, and fault tolerance.
💡 Top Tips to Prepare
- Focus on memorizing the shared responsibility model for IaaS, PaaS, and SaaS as it is a key differentiator.
- Create real-world scenarios to distinguish between scalability (scaling up/out) and elasticity (automated scaling).
- Thoroughly understand the financial shift from a CapEx model to an OpEx model and its benefits for business agility.
- Utilize Oracle's official free training materials to solidify your understanding of core terms like HA, DR, and fault tolerance.
📖 About this Domain
This domain covers the financial and operational frameworks of Oracle Cloud Infrastructure. It focuses on OCI pricing models, cost management tools, and available support plans. Understanding these components is critical for effective tenancy management and governance.
🎓 What You Will Learn
- Differentiate OCI pricing models like Pay As You Go (PAYG) and Universal Credits, including rate cards and cost analysis.
- Utilize OCI cost management tools such as Budgets, Cost Analysis, and Usage Reports for cloud spend governance.
- Define and interpret OCI Service Level Agreements (SLAs), including service credit policies and availability metrics.
- Describe OCI support plans, their scope, response times, and the process for creating a service request (SR).
🛠️ Skills You Will Build
- Perform cost estimation using the OCI Cost Estimator and analyze usage reports for expenditure forecasting.
- Implement cost controls by configuring Budgets and setting up alerts to prevent cost overruns in a tenancy.
- Evaluate OCI SLAs to align architectural designs with specific business availability and performance requirements.
- Engage Oracle Support efficiently by creating and managing service requests based on your subscribed support plan.
