The Oracle Cloud Infrastructure Architect Professional course on Udacity provides a comprehensive overview of Oracle Cloud services and technologies. Students will start by signing up for a free tier account and learning how to navigate the OCI Console. They will then dive into designing and implementing real-world network architectures, focusing on scalability and resilience. The course also covers cloud-native, microservices, and serverless architecture, as well as infrastructure-as-code using Terraform. Students will explore deploying and managing Oracle Database Cloud Service and Autonomous Database, as well as designing for hybrid cloud architecture and migrating on-premises workloads to OCI. Security and compliance are also addressed, with lessons on OCI WAF, certificates, vulnerability scanning, and Oracle Data Safe. Real-world architectures such as hub-spoke, HPC, and security architecture are explored. The course concludes with preparation for the OCI Architect Professional Certification, including practice exam questions. Students will also be provided with guidance on what to explore next in their cloud journey.
