A multi-cloud strategy uses services from more than one cloud vendor. It helps improve resilience, avoid vendor lock-in, and optimize performance by picking the best tools from each provider.
For complete preparation, combine this set with full subject-wise practice for Cloud Basics. You can also explore other subjects and sets from the links below.
Tools like Terraform, Anthos, and Azure Arc provide unified management. They allow consistent policy enforcement, deployment, and monitoring across environments.
A hospital might keep patient data on-prem for compliance but use public cloud for analytics. This mix ensures both security and flexibility without moving sensitive data outside control.
Common issues include incompatible APIs, data transfer costs, and re-architecting apps. Testing and phased migration help reduce downtime and risk during transitions.
AWS Storage Gateway connects on-prem applications with cloud storage. It provides hybrid data access for backups, archives, or file sharing.
Implement unified IAM policies, encrypt data at rest and in transit, and use secure VPN or private links. Continuous monitoring and centralized logging keep visibility across all environments.
Hybrid cloud combines on-premise infrastructure with public or private cloud services. It allows secure data sharing and flexible scaling between both environments.
Vendor lock-in happens when applications rely heavily on one provider’s tools and APIs. Switching providers becomes expensive and complex due to compatibility issues.
Global load balancers manage incoming requests across multiple cloud regions or vendors. This improves fault tolerance and reduces latency for global applications.
Asynchronous replication copies data between environments without blocking operations. It ensures near-real-time synchronization between cloud and on-prem systems.
AWS Direct Connect and Azure ExpressRoute create dedicated private links. They offer better security and lower latency compared to public internet connections.
Google Anthos allows consistent Kubernetes cluster management across on-prem and cloud providers. It standardizes policies and deployment pipelines across environments.
VM Import/Export allows transferring existing VMs to and from AWS. Similar tools exist in Azure (Migrate) and GCP (Migrate for Compute Engine).
A multi-cloud setup avoids vendor lock-in and improves redundancy. It also lets organizations pick specialized services from each provider for performance or cost advantages.
