As organizations navigate the complex world of cloud computing architecture and services, they often encounter two terms that are frequently used interchangeably: “multi-cloud” and “hybrid cloud”. While both concepts involve using multiple computing environments, there are distinct differences between the two.

Multi-cloud is the use of multiple cloud computing services from different providers, such as using both AWS and Azure. Hybrid cloud, on the other hand, is a combination of public cloud services and private on-premises infrastructure, allowing workloads to move between the two environments as needed.

Dgtl Infra explores the key differences between multi-cloud and hybrid cloud environments, including their unique characteristics, benefits, and challenges. We also examine the powerful combination of both approaches, known as hybrid multi-cloud, and provide real-world examples to illustrate its application. You will gain a comprehensive understanding of these cloud strategies and how they can be leveraged to optimize your organization’s IT infrastructure, enhance workload flexibility, and drive business growth.

Understanding Multi-Cloud and Hybrid Cloud

A multi-cloud architecture uses cloud services from multiple public cloud providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). This approach allows organizations to cherry-pick the best services and features from each provider, avoiding vendor lock-in and delivering optimal performance for specific workloads. For example, a company might use AWS for its extensive storage options like S3 (Simple Storage Service), Azure for its strong integration with Microsoft tools, and Google Cloud for its machine learning (ML) capabilities.

On the other hand, hybrid cloud architecture combines public cloud services with private cloud or on-premises infrastructure. In this model, organizations maintain control over sensitive data and mission-critical applications by keeping them in their private environment while leveraging the public cloud for less critical workloads or burst capacity. This approach enables businesses to comply with strict security and regulatory requirements (e.g., HIPAA in the U.S. healthcare industry) while still benefiting from the scalability and cost-efficiency of public cloud services.

Hybrid Multi-Cloud – Combining Both Environments

To add another layer of complexity, the terms “multi-cloud” and “hybrid cloud” are often combined to describe a “hybrid multi-cloud” architecture.

In a hybrid multi-cloud setup, an organization uses a mix of public cloud services from multiple providers (multi-cloud) in conjunction with their private cloud and/or on-premises infrastructure (hybrid cloud). This approach allows businesses to take advantage of the unique strengths and services offered by different public cloud providers while still maintaining control over sensitive data and mission-critical applications in their private environment.

Presently, nearly 60% of enterprises are adopting a hybrid multi-cloud architecture. This architecture employs a hybrid IT environment that integrates on-premises systems with external cloud/hosted resources, facilitating workload portability and interoperability between environments.

Example of Hybrid Multi-Cloud

An organization might choose to deploy a hybrid multi-cloud architecture by using a combination of Amazon Web Services (AWS) and Microsoft Azure public cloud services for different applications, while keeping sensitive customer data stored on their own private cloud infrastructure, managed either by the organization itself or by a third-party private cloud provider such as Hewlett Packard Enterprise (HPE).

Multi-CloudHybrid Cloud
InfrastructurePublic cloud services from multiple vendorsPublic and private cloud, may include on-premises resources
WorkloadsDistribute workloads across multiple public cloud platformsWorkloads can run on public cloud or private infrastructure
DataData distributed and managed separately across multiple public cloud platformsData can reside and be managed centrally across public and private environments
Vendor Lock-InReduces vendor lock-in by using multiple providersPotential lock-in if heavily reliant on a single public cloud
ComplexityComplex to manage and integrate services from multiple public cloudsVery complex; requires integration and management of different environments
Use CasesOrganizations seeking best-of-breed services from multiple providersOrganizations requiring scalability of public cloud and control of on-premises resources
SecurityRelies on security measures of each cloud providerAllows for more control over sensitive data and workloads
CostPay for services used from each cloud providerOptimizes costs by balancing public cloud and owned resources

1. Infrastructure and Architecture

  • Multi-Cloud: Involves using multiple public cloud providers, each with its own infrastructure and management tools. In a multi-cloud setup, supporting services like authentication, databases, and monitoring are hosted in the public cloud, either with the same provider offering compute, storage, and networking services, or with a different cloud provider
  • Hybrid Cloud: Integrates private, on-premises infrastructure – such as servers, storage, and networking – with public cloud services. This allows workloads to move between the two and supports additional functions like authentication, security, databases, and monitoring

2. Workload Distribution

  • Multi-Cloud: Workloads are distributed across different cloud providers based on specific requirements, such as cost, performance, or features
  • Hybrid Cloud: Workloads can run on either private or public cloud infrastructure, depending on factors like security, compliance, and scalability

3. Data Management

  • Multi-Cloud: Data may be stored and managed separately across different public cloud providers, requiring careful coordination and integration
  • Hybrid Cloud: Data can be seamlessly shared and moved between private and public cloud environments, often using unified management tools. Sensitive data can also be safely stored in a company-controlled private cloud

4. Vendor Lock-In

  • Multi-Cloud: Reduces vendor lock-in by allowing organizations to choose the best services from multiple public cloud providers and avoid dependence on a single vendor
  • Hybrid Cloud: Can still involve some degree of vendor lock-in, especially if the private and public cloud components are tightly integrated or if only a single public cloud provider is used

5. Complexity

  • Multi-Cloud: Complex to manage due to the need to coordinate and integrate services from multiple providers, each with its own tools and APIs
  • Hybrid Cloud: Very complex due to the need to integrate and manage a mix of on-premises infrastructure and public cloud services, which often use differing technologies and have varying security needs. However, hybrid cloud environments typically include unified management tools that help simplify this administration and orchestration

6. Use Cases

  • Multi-Cloud: Suitable for organizations seeking to optimize costs, avoid vendor lock-in, leverage the best services from different providers, and scale resources as needed in the public cloud
  • Hybrid Cloud: Ideal for businesses with legacy systems, strict compliance requirements, or the need to maintain control over certain workloads. However, flexibility and scalability are more limited by the private cloud component

7. Security

  • Multi-Cloud: Requires a comprehensive security strategy to manage and monitor multiple cloud environments, with consistent policies and controls across providers
  • Hybrid Cloud: Allows for more control over sensitive data and workloads by keeping them on-premises, while still leveraging the security features of public cloud providers for web-facing applications, data backup, and disaster recovery
