Multi-cloud architectures, therefore, are becoming the norm rather than the exception. Such architectures are designs that utilize multiple cloud services, either from the same or different providers, to achieve a set of specified goals.

This section will delve into some prevalent multi-cloud architecture designs and explain their nuances.

Cloudification

At the heart of any cloud strategy lies the process of "Cloudification." It refers to the transformation of applications and workloads, making them cloud-ready or optimized for cloud environments.

Cloudification is not just about lifting and shifting applications to the cloud. It's about understanding the unique characteristics of cloud environments and optimizing applications to take full advantage of those characteristics. This design principle ensures efficient resource utilization, scalability, and high performance in cloud environments.

Multi-cloud Relocation

Multi-cloud relocation is a dynamic process wherein applications, workloads, or data move across multiple cloud providers. This movement is based on various factors like cost-effectiveness, performance, and changing business requirements.

By embracing this multi-cloud design architecture, organizations can remain agile, harnessing the best from each cloud provider based on real-time conditions and needs.

Multi-cloud Refactor

To get the most out of multi-cloud environments, sometimes applications need tweaking. Multi-cloud refactor involves adapting or redesigning these applications to align better with the capabilities of different cloud providers.

This might involve changing certain application functionalities or incorporating new features to ensure that applications run seamlessly, regardless of the cloud provider.

Multi-cloud Rebinding

In the ever-evolving cloud ecosystem, there might arise a need to switch applications or workloads from one cloud provider to another. Multi-cloud rebinding addresses this by allowing a dynamic switch based on triggers like cost, performance, or even regulatory considerations.

Such a design ensures that businesses are always operating optimally, capitalizing on the strengths of various cloud providers as situations demand.

Multi-Cloud Rebinding with Cloud Brokerage

Enter the cloud brokers – the entities that make rebinding smooth. They act as the middlemen, facilitating the switch between cloud providers. By integrating cloud brokerage services, organizations can ensure that the transition between different cloud providers is seamless, efficient, and optimized for their specific needs.

This setup is particularly beneficial for organizations that frequently shift between providers, ensuring that transitions are hassle-free and efficient.

Multi-application Modernization

In a multi-cloud environment, older applications might not harness the cloud's full potential. Multi-application modernization focuses on transforming these legacy applications, making them cloud-native.

This involves employing modern development practices and technologies, ensuring that these applications are scalable, resilient, and fully optimized for multi-cloud environments.

Incorporating these multi-cloud architecture designs can significantly bolster an organization's cloud strategy, ensuring flexibility, performance optimization, and cost efficiency. As cloud technologies continue to evolve, staying abreast of these designs will be crucial for any organization's cloud success.

The process of setting up and deploying multi-cloud architectures can differ significantly, depending on your specific use case and needs. Let’s discuss some of the most common patterns.

Distributed Deployment Patterns

This subcategory can be broken down into the following patterns:

• Tiered Hybrid Pattern: It’s a pattern where your application’s tiers are spread out among multiple clouds. For instance, you may host your app’s backend on one cloud and the database — on another.
• Partitioned Multi-Cloud Pattern: In this pattern, your app’s functional components are hosted across diverse cloud environments.
• Cloud Analytics Pattern: This pattern involves executing analytics tasks on a separate cloud while the main application’s processes stay unchanged.
• Edge Hybrid: It combines edge computing assets with cloud resources, letting you improve performance by handling data closer to its source.

Redundant Deployment Patterns

This one comprises three pattern types:

• Hybrid Environment: This pattern is all about striking the right balance between on-premises infrastructure and the cloud.
• Business Continuity Hybrid and Multi-Cloud: This pattern is a solution for disaster recovery scenarios and involves deploying critical applications across multiple clouds.
• Cloud Bursting: In this case, applications seamlessly expand into additional cloud resources during peak periods.

Multi-cloud and hybrid cloud are often used interchangeably. Of course, they’ve got similarities, but also some features that set them apart.
