A retail company is migrating their e-commerce application to IBM Cloud. They need to ensure the application can automatically scale during peak shopping seasons while minimizing costs during off-peak periods. The application consists of web servers, application servers, and a database tier. Which cloud service model and deployment strategy would best meet these requirements?

An organization is designing a multi-tier application on IBM Cloud that requires different security zones for public-facing web servers, internal application logic, and backend databases. Network traffic between tiers must be controlled and monitored. Which IBM Cloud networking approach should be implemented?

A development team is using IBM Cloud Kubernetes Service and needs to implement a CI/CD pipeline that automatically deploys containerized applications to development, staging, and production clusters. The solution must support automated testing and rollback capabilities. Which combination of IBM Cloud services would best support this requirement?

A financial services company must comply with regulations requiring data residency in specific geographic regions and encrypted data both at rest and in transit. They are planning to use IBM Cloud Object Storage for archival data. What configuration approach should they implement?
