Explore ownership models in cloud, from on-premise and private clouds to public, hybrid, and multi-cloud deployments, highlighting flexibility, pay-per-use, and scalable infrastructure.

Understand shared responsibility in public cloud, where providers handle availability and security features while tenants own data, applications, and recovery planning, including hybrid and multi-cloud strategies.

Explore high availability, disaster recovery, and scalability in on premise infrastructure, balancing non-functional requirements with data locality, regulatory compliance, and cloud provider implications.

High availability defines uptime targets for an application, including planned and unplanned downtime and redundancy to tolerate faults, with higher targets like 99.9% or multi-nine levels for critical apps.

Understand fault tolerance by identifying possible faults and deciding what to tolerate, then design redundancy with storage and application servers across racks, using active-active or active-passive setups.

Plan multi-site disaster recovery by deploying active-active or active-passive architectures, enabling replication of data across distant data centers to meet RTO and RPO goals while considering regulatory requirements and cost.

Plan high availability and scalability with fault tolerance and redundancy. Prepare for data center and hardware failures by testing recovery procedures across cloud environments.

Explore Oracle Cloud Infrastructure and Oracle Cloud applications, identify IaaS and PaaS components like storage, networking, compute, databases, native VMware, AI, analytics, and SaaS for the associate architect certification.
