Multicloud Fundamentals & OCI Multicloud Networking
Define multicloud, hybrid cloud, and distributed cloud in your own words and contrast them with single-cloud multi-region designs
Map the OCI regions and Azure interconnected regions and explain how region pairing affects latency and data residency
Diagram the physical path of a packet from an Azure VNet to an OCI VCN, labeling the interconnect, FastConnect, and ExpressRoute hops
List the shared responsibility split for compute, network, and identity across Oracle and Microsoft control planes
Your checkpoint
A one-page labeled network diagram plus a 300-word glossary of multicloud terms you can explain without notes
OCI Multicloud Networking
Provision an OCI VCN with public and private subnets, route tables, and a NAT gateway sized for a three-tier workload
Configure security lists and network security groups and justify each rule against a least-privilege model
Trace how CIDR ranges must be non-overlapping across the Azure VNet and OCI VCN and resolve one deliberate overlap
Compare FastConnect, ExpressRoute, and site-to-site VPN for cost, latency, and failover behavior
Your checkpoint
A working VCN design document with CIDR allocation table, route tables, and a written failover plan for loss of the primary interconnect
OCI Multicloud Networking & Identity and Access Management Across Clouds
Set up an OCI-Azure interconnection and validate bidirectional traffic with ping and traceroute between test instances
Configure DNS resolution across both clouds so a hostname in one resolves from the other
Create OCI IAM users, groups, and dynamic groups and attach policies scoped to a compartment
Federate an identity provider so a single user sign-in reaches both OCI and Azure resources
Your checkpoint
A connectivity test log showing successful cross-cloud ping, traceroute, and DNS resolution, plus a screenshot-free written policy matrix
Identity and Access Management Across Clouds
Design a role mapping table that translates Azure RBAC roles to OCI policies for a shared application team
Write OCI policies that grant least privilege for a specific workload and prove they deny an out-of-scope action
Explain how instance principals and dynamic groups remove stored credentials from cross-cloud automation
Audit an existing policy set and remove at least two over-broad statements
Your checkpoint
A completed role-mapping matrix covering five personas, with each OCI policy statement paired to its Azure RBAC equivalent and a denial test result
Multicloud Data and Application Architectures
Design a data architecture that keeps the system of record in one cloud and serves reads from the other, stating the consistency tradeoff
Choose between replication, change data capture, and API-based sync for a given latency and volume profile
Model the cost of cross-cloud egress for a workload moving 2 TB per month and identify the break-even point for a caching tier
Deploy a stateless application tier in one cloud backed by a managed database in the other and document the failure modes
Your checkpoint
A data flow architecture document with a consistency model, an egress cost estimate, and a table of failure modes with mitigations
Multicloud Data and Application Architectures & Operations, Security, and Governance in Multicloud
Implement a retry and circuit-breaker pattern for a cross-cloud API call and demonstrate behavior under induced latency
Define RTO and RPO targets for the workload and map each to a concrete replication or backup mechanism
Configure centralized logging so events from both clouds land in one queryable store
Set up budget alerts and cost tags that attribute spend to the correct cloud and team
Your checkpoint
A resilience test report showing measured recovery time against the stated RTO, plus a cost attribution dashboard definition
Operations, Security, and Governance in Multicloud
Write an encryption and key management plan covering data at rest and in transit across both clouds
Define a secrets management approach and rotate one credential end to end
Draft an incident response runbook for loss of the cross-cloud link, including escalation and communication steps
Map the workload against a compliance framework and list the controls that span both providers
Your checkpoint
A security and governance package containing the key management plan, the incident runbook, and a control mapping table
Multicloud Fundamentals & OCI Multicloud Networking & Identity and Access Management Across Clouds & Multicloud Data and Application Architectures & Operations, Security, and Governance in Multicloud
Re-answer missed practice questions from weeks 1 through 7 and write the reason each wrong answer was tempting
Build a one-page decision cheat sheet for interconnect choice, identity federation, and data placement
Walk through a full architecture scenario end to end within a 30-minute time box
Identify your two weakest domains by scored practice and schedule targeted review of each
Your checkpoint
A scored 60-question practice run with a written remediation list for every domain scoring below 80 percent
Milestones
Week 4: You can explain the Azure-to-OCI traffic path from memory and your connectivity log proves bidirectional traffic with working cross-cloud DNS
Week 6: Your cross-cloud workload survives an induced link failure within the stated RTO, and egress cost is estimated within 15 percent of a measured bill
Week 8: Practice exam score of 80 percent or higher overall with no domain below 70 percent
