Difference between Hybrid cloud and multi-cloud

• Architecture: In a hybrid cloud environment, both private and public cloud services are combined, with the private cloud resource typically owned and managed by the users. This private aspect is often hosted in-house, on-premises data centers, or dedicated servers in third-party data centers and syncs with public cloud workloads to form a comprehensive business solution. 
  On the other hand, multi-cloud systems solely utilize public cloud services without the incorporation of private cloud resources.

• Data storage: Hybrid Cloud mixes private and public cloud storage, keeping sensitive data in the private cloud for control and security, and using the public cloud for non-sensitive data to save costs and improve scalability. Multicloud uses multiple public cloud services only, spreading data across providers for better storage efficiency and performance.

• Cost: A company using a hybrid cloud model may experience higher costs, especially when hosting the private cloud on-premises, which requires purchasing, managing, and maintaining the resource. 
  In contrast, multi-cloud solutions relying on public cloud resources are more cost-effective, as they eliminate the need for initial spending. Leveraging the purchasing power of public cloud vendors allows multi-cloud users to access cutting-edge technology at a more affordable price.

• Security: One significant advantage of the hybrid cloud is that companies can control physical access to their private cloud hardware, which is particularly valuable in heavily regulated industries. In contrast, multi-cloud solutions do not offer the same control over physical infrastructure access, although they usually implement robust security measures to protect it.

• Availability: Multi-cloud ensures high availability with reliable public cloud resources, allowing seamless switching between them in case of outages. A hybrid cloud may face downtime if the private resource requires maintenance without a backup resource available.

Hybrid Cloud vs Multi-cloud: Using Scenarios

To determine the most suitable cloud strategy for specific scenarios, it's essential to explore when to utilize Hybrid Cloud and when to opt for Multicloud.

When to use the hybrid cloud?

A business needs cloud flexibility, resources, and services. Still, due to choice or regulatory standards, certain data or workloads must be hosted locally within the organization's on-premises data centers or direct geopolitical control. For instance, while building cloud-native applications and hosting some applications in the public cloud, critical workloads must remain on-site to meet specific requirements.

When to use multi-cloud?

Companies can use services, resources, and cost models from different cloud providers, such as virtual machines and storage from one cloud provider, business applications from different SaaS providers, and AI/ML or language cloud services from others.
