Multi Cloud

What is Multi Cloud?

Multi cloud is a cloud computing model where an organization distributes assets over at least two clouds from different public cloud or private cloud providers. Multi cloud involves strategically using several cloud solutions from multiple suppliers. This method diversifies cloud infrastructure, reducing risk and vendor lock-in. It lets organizations choose the finest services and pricing models from several providers to maximize performance and efficiency. Multi cloud deployments reduce the effect of provider outages and interruptions. It also allows workload deployment across cloud environments to meet requirements and regulatory compliance.

What is the difference between multi cloud and hybrid cloud?

There are variations between multi cloud and hybrid cloud service deployment and management:

Multi cloud:  Multi cloud refers to using multiple cloud computing and storage services within a single network architecture. Workloads are distributed among public clouds, private clouds, or both under this technique. Each cloud service provider has different features, prices, and geographies. Organizations use multi cloud to prevent vendor lock-in, increase redundancy, maximize performance, and use services from different providers. 

Hybrid cloud: This computing environment allows data and programs to be exchanged between public and private clouds. A hybrid cloud system utilizes a combination of private and public cloud architectures to host resources and workloads. The hybrid cloud architecture offers flexibility, scalability, and security by keeping sensitive data and important apps on-premises and using the public cloud for other workloads.

In conclusion, hybrid cloud integrates public and private cloud environments to build a cohesive architecture, whereas multi cloud uses numerous cloud services from different providers.

What are the pros and cons of using a multi cloud strategy?

There are pros and cons to using a multi cloud strategy. The following are some advantages and disadvantages:


  • Reduced Vendor Lock-in: Multiple cloud providers allow enterprises to negotiate better prices and conditions.

Key Components of a Successful Multi Cloud Strategy

Cloud Agnostic Architecture: 

  • Concept: Cloud-agnostic architecture designs apps and infrastructure independent of cloud providers. It offers flexible workload deployment and migration between cloud environments. 
  • Importance: Decoupling apps from cloud services decreases vendor lock-in, improves portability, and facilitates cloud migration. 
  • Examples: Kubernetes, Docker, Terraform, and Ansible abstract infrastructure and automate deployment across different clouds, enabling cloud-agnostic development. 


Governance and Compliance: 

  • Need: Strong governance policies manage resources, costs, security, and compliance across different cloud environments. 
  • Challenges: Multi cloud businesses face regional and industry-specific compliance obligations. 
  • Best Practices: Centralized governance structures, explicit policies, frequent audits, and automation for enforcement. 


Optimizing Costs: 

  • Impact: Workload placement, data transfer fees, and cloud provider pricing structures might affect multi cloud expenses positively or adversely. 
  • Strategies: Cost-saving techniques include using reserved instances or committed usage discounts, optimizing resource use, and distributing workloads according to performance needs. 


Privacy and Security: 

  • Considerations: Multi cloud security involves uniform security measures, encryption, access management, and identity management across all cloud platforms. 
  • Encryption: Protecting sensitive data at rest and in transit by encryption. 
  • Access Controls: Granular and role-based access control (RBAC) restrict resource access to approved users. 
  • Data Protection: Multi cloud backup, replication, and disaster recovery protect data against loss or corruption. 


Addressing five important components can help organizations achieve their business goals with a durable, cost-effective, and secure multi cloud strategy.
