In today's digital landscape, where agility, scalability, and efficiency are key benchmarks, multi-cloud migration has emerged as a beacon of innovation for businesses seeking to optimize their IT infrastructure. What exactly does it entail, and how does it differ from other cloud migration strategies?

In this comprehensive guide, we'll explore the intricacies of multi-cloud transformation, review the strategies to achieve it, and provide real-world examples to illuminate its potential.


What Is a Multi-Cloud Approach for Multi-Cloud Migration?

At its core, a multi-cloud approach refers to using multiple cloud service providers to meet diverse business needs. Rather than relying solely on a single provider, organizations leverage a combination of public, private, or hybrid clouds to achieve greater flexibility, resilience, and cost-effectiveness.

By migrating their data and processes to multiple clouds, businesses can distribute workloads strategically across different platforms based on specific requirements such as performance, compliance, or geographic location.

What Are the Benefits of Migrating to a Multi-Cloud Infrastructure?

In a recent Deloitte survey, 88% of respondents stated that cloud technology was the foundation of their digital strategy. Before diving into multi-cloud deployment strategies, it helps to understand the many benefits of undertaking this type of migration.

High ROI

In a rapidly changing IT landscape, predicting the perfect cloud platform for your business can be challenging due to differences in infrastructure, functionality, and pricing. By employing various vendors for integration and support, a multi-cloud migration maximizes returns on cloud investment, leveraging a diverse range of computing and business functions.

Enhanced Security

Public cloud platforms lack transparency and control over databases, while private clouds offer robust security at a higher cost. With a multi-cloud setup, businesses can keep sensitive data in private clouds while running regular applications cost-effectively through public clouds, striking a balance between security and affordability.

Low Latency

Latency, or delays in accessing data, is common in cloud services due to data traveling between distant servers. In a multi-cloud setup, data centers closest to end-users minimize latency, providing a unified experience across geographies and ensuring prompt data access.

Optimal Disaster Recovery

Multi-cloud infrastructure distributes data across multiple platforms, facilitating collaborative handling of security breaches and compliance issues. With primary and secondary servers geographically separated, the risk of system-wide disruptions due to disasters or cyberattacks is significantly reduced, ensuring optimal disaster recovery.

Greater Autonomy

Adopting a multi-cloud migration approach minimizes vendor lock-in, providing flexibility to choose or switch cloud providers based on changing business needs. This modular setup offers a backup plan in case of vendor issues, ensuring continuity without compromising the entire cloud environment.

Advanced Scalability and Security

Multi-cloud platforms offer scalability options as businesses grow, allowing seamless transition between cloud providers without affecting applications. With multiple cloud infrastructures, there's no single point of failure, ensuring uninterrupted service even in the event of infrastructure or network failures.

Cost Optimization

A multi-cloud strategy enables businesses to choose affordable cloud providers while satisfying business needs. By deploying both private and public clouds, cost optimization is achieved through proper planning and knowledge, ensuring long-term savings.

Efficient Data Management

In a multi-cloud strategy, each data parcel is suitably located, optimizing data management while minimizing overhead expenses. Tailored architectural requirements for safe storage maintain data sovereignty, and the processing capacity of hardware and software assets is enhanced through balanced data load distribution.

What Are the 5 Primary Multi-Cloud Migration Strategies?

When embarking on the journey of cloud migration, businesses should adopt strategies tailored to their unique objectives and constraints. Here are five commonly employed cloud migration strategies.

1. Lift and Shift

Lift and shift, also called rehosting, is a simple cloud migration strategy that involves transferring applications or workloads from on-premises infrastructure to the cloud with minimal modifications. Essentially, it's like picking up your existing setup and moving it as is to the cloud. This approach offers a quick and straightforward migration path, ideal for organizations looking to expedite their transition to the cloud without overhauling their existing systems.

While lift and shift makes for a fast multi-cloud migration process, it can deny businesses many advantages of the cloud. Since applications are migrated without significant modifications, they may not fully leverage the scalability, elasticity, and agility offered by cloud environments. Additionally, while this strategy may provide immediate cost savings by eliminating on-premises hardware and maintenance costs, it could come at the cost of suboptimal performance and inefficient resource utilization in the long run.

2. Replatforming

Replatforming, also known as lift, tinker, and shift or lift and reshape, balances speed and optimization by making adjustments to applications or workloads so that they are optimized for the target cloud environment. Unlike lift and shift, which involves minimal changes, replatforming means fine-tuning applications to take advantage of cloud-specific features and capabilities.

This approach allows businesses to optimize their applications for performance, scalability, and cost-efficiency within the cloud environment. For example, organizations may refactor their databases to use cloud-native storage solutions or rearchitect their applications to leverage auto-scaling and load-balancing features. Replatforming enables organizations to achieve significant benefits without the complexity of a complete overhaul by optimizing applications for the cloud while minimizing the need for extensive redesign.

3. Refactoring

Refactoring is the most comprehensive multi-cloud migration strategy, requiring organizations to redesign or rearchitect their applications to fully leverage cloud-native capabilities. Unlike lift and shift or replatforming, which focus on migrating existing systems with little change, refactoring involves fundamentally transforming applications to embrace cloud-native architectures and services.

While refactoring offers the potential for significant performance and cost optimizations, it requires substantial time, resources, and expertise. Organizations must carefully assess their applications, identify dependencies, and re-engineer them to leverage cloud-native technologies such as serverless computing, microservices, and containerization. While the upfront investment and effort involved in refactoring may be considerable, the long-term benefits in terms of scalability, agility, and cost savings can be substantial.

4. Relocating

This strategy focuses on moving virtualized workloads from on-premises data centers to the cloud seamlessly. Unlike other migration strategies that may involve significant modifications or rearchitecting of applications, this approach allows organizations to migrate their existing virtualized environments as is, minimizing disruption and simplifying the migration process.

The relocating strategy allows businesses to migrate their virtualized workloads to the cloud without investing in new hardware infrastructure. This multi-cloud migration approach eliminates the need for upfront capital expenditures and allows organizations to leverage their existing virtualized environments in the cloud. Since there are no significant rewrites or refactoring, this option minimizes the risk of compatibility issues and reduces the time and resources required for migration.

5. Repurchasing

Repurchasing, sometimes referred to as "drop and shop," involves replacing existing software or applications with cloud-based alternatives. This strategy entails migrating from on-premises software licenses or proprietary systems to cloud-based software as a service solutions or open-source alternatives.

While repurchasing may require upfront investment in new software licenses or subscription fees, it can lead to long-term cost savings, enhanced functionality, and improved scalability. Cloud-based SaaS solutions often offer subscription-based pricing models, eliminating the need for upfront capital expenditures and reducing ongoing maintenance costs.

Additionally, SaaS applications are typically updated and maintained by the provider, ensuring organizations have access to the latest features and security patches without the need for manual intervention. By embracing repurchasing, organizations can modernize their software stack, improve operational efficiency, and position themselves for future growth and innovation in the cloud era.
