Multicloud migration
A clear trend has emerged: organizations are shifting to multicloud strategies to enhance their IT infrastructure. Multicloud migration, the distribution of digital assets across multiple cloud environments from different providers, offers unprecedented flexibility, scalability, and resilience. Cloud-to-cloud migration also plays a crucial role, enabling smooth transitions between providers.
This approach allows businesses to harness the unique strengths of each cloud provider, optimizing performance and cost while mitigating the risks of relying on a single vendor. While multicloud migration presents integration complexities, its strategic implementation is vital for maintaining a competitive edge, ensuring robust data protection, and complying with diverse regulations. This marks a significant shift in how businesses manage IT resources in the global market.
What is multicloud?
Multicloud architecture is a strategic approach to IT management that involves using multiple cloud computing and storage services from various providers within a single, diverse environment. This approach leverages the strengths of different cloud services to create a more robust, flexible, and scalable IT infrastructure. It allows businesses to integrate a wide range of cloud resources, optimizing their systems for specific tasks by tailoring resources to the performance requirements and workload characteristics of each application.
This deployment model offers several benefits, including:
- Enhanced performance and reliability: Distributing workloads across multiple cloud environments reduces dependency on a single provider, minimizing downtime risk.
- Cost efficiency: Choosing from a variety of cloud services enables businesses to take advantage of competitive pricing and avoid vendor lock-in, allowing them to switch platforms as their needs evolve.
- Strategic flexibility: Multicloud solutions provide greater control over IT capabilities, aligning them more closely with business objectives.
Types of cloud platforms
Cloud platforms can be classified into various types based on deployment models and service offerings:
4 main types of cloud computing
The cloud computing landscape includes four main types, each designed to meet different business needs and security requirements, helping organizations optimize their IT strategies.
- Private cloud
This cloud environment is exclusively used by a single organization and offers the highest level of security and control. A private cloud is either hosted on-premises or by a third-party provider but remains within a private network. This isolation from public networks enhances security, making private clouds ideal for businesses with sensitive data or strict regulatory requirements.
- Public cloud
Public clouds are operated by third-party providers like Google Cloud, Amazon Web Services (AWS), and Microsoft Azure. Resources such as servers and storage are delivered to clients over the internet. The public cloud model offers scalability, elasticity, and a pay-as-you-go pricing structure. It is a cost-effective and easily deployable solution, as the cloud provider owns and manages the hardware, software, and infrastructure. This is well-suited for companies seeking to avoid the capital expenditures of maintaining physical servers.
- Hybrid cloud
A hybrid cloud environment combines private and public clouds, and can also include traditional on-premises infrastructure, allowing data and applications to move between these environments as needed. This flexibility provides businesses with more deployment options and data management strategies. Hybrid clouds help optimize existing infrastructure, enhance security, and ensure compliance. They are particularly useful for balancing workloads, managing data throughout its lifecycle, and meeting legal and regulatory data storage requirements while maintaining the security and control of a private cloud and the agility of a public cloud.
- Multicloud
Multicloud involves using multiple cloud services from different providers. It may include a combination of private and hybrid cloud infrastructures. Unlike hybrid cloud, which emphasizes integration and orchestration between cloud types, multicloud focuses on orchestration between different cloud types without necessarily integrating them. This approach offers several advantages, including vendor agnosticism, improved performance, and enhanced redundancy and disaster recovery capabilities. Organizations can choose the best cloud services for specific tasks and operational requirements from a wider range of providers.
Multicloud vs. hybrid cloud
While both multicloud and hybrid cloud architectures involve using multiple cloud services, the key difference lies in their underlying structure.
Multicloud refers to the use of multiple cloud services from various providers, which may or may not be integrated with each other. This approach allows organizations to leverage the strengths of different providers and tailor their cloud solutions to specific needs.
In contrast, hybrid cloud combines a private cloud with one or more public cloud services within a unified environment. This allows businesses to maintain sensitive data or workloads in their private cloud while leveraging the scalability and cost-effectiveness of public clouds for other applications.
3 main types of cloud computing services
Cloud computing services have transformed how businesses deploy and manage technology. At a high level, these services can be categorized into three main types, each serving distinct roles within the IT ecosystem and catering to different business needs:
- Software as a Service (SaaS)
SaaS embodies the principle of distribution, where software is hosted in the cloud and delivered as a service, accessible online. This often refers to web-based applications that customers can access via subscription from any internet-connected device using a web browser. The software vendor is responsible for hosting and maintaining the application's servers, databases, and code. Users benefit from not needing to invest in extensive hardware, installation, maintenance, or updates. Examples of SaaS include learning management systems (LMS), customer relationship management (CRM) systems, and various digital tools.
- Infrastructure as a Service (IaaS)
IaaS is the most fundamental cloud service model, offering virtualized physical computing resources over the internet. It provides highly scalable and automated compute resources, including virtual servers and storage capacity. IaaS is often used by organizations seeking to avoid the capital expense and complexity of managing their own physical servers and data center infrastructure. Each resource is offered as a separate service component, and users rent only what they need for the duration required. IaaS provides flexibility in automated deployments of servers, processing power, storage, and networking, enabling rapid scaling up or down as needed.
- Platform as a Service (PaaS)
PaaS provides application developers with an environment for developing and customizing applications. Cloud providers offer networks, servers, storage, and other services necessary for hosting, developing, testing, and running applications over the internet. Developers can utilize these resources without building or managing the underlying infrastructure. This allows businesses to focus on growth and innovation, rather than infrastructure management. PaaS supports the entire lifecycle of web applications, from building and testing to deploying, administering, and updating.
What is a multicloud migration?
Multicloud migration is the strategic process of moving digital assets from local on-premises infrastructure to multiple cloud environments, each consisting of more than one cloud platform. This approach aims to leverage the unique benefits of various cloud providers, such as improved scalability, performance, and fault tolerance. By avoiding over-reliance on a single cloud, organizations can optimize operations for efficiency and performance.
This shift requires a detailed plan addressing compatibility, complexity management, and alignment with business objectives. A successful multicloud migration involves:
- Assessment and selection: Evaluating the existing IT landscape and selecting the right cloud services to meet specific organizational needs.
- Phased migration: Implementing the migration in stages, addressing technical and security considerations at each phase.
- Data security: Ensuring data is secure both in transit and at rest across various platforms.
- Application optimization: Fine-tuning or re-engineering applications to leverage the capabilities of the chosen cloud services.
- Regulatory compliance: Ensuring compliance with data sovereignty and other regulations, especially in global operations.
A well-executed multicloud migration enhances operational flexibility and positions enterprises to capitalize on cloud innovation and cost management.

Organizations embrace multicloud strategies for a variety of compelling reasons:
- Risk mitigation: A primary driver for adopting multicloud is to mitigate the risks associated with IT infrastructure failure. By distributing data, applications, and services across multiple cloud platforms, organizations ensure that a failure or downtime in one cloud does not disrupt the entire operation. This diversification, both geographically and across vendors, significantly reduces the risk of service outages and data loss, preserving business continuity and strengthening disaster recovery capabilities.
- Flexibility and scalability: Multicloud environments offer unparalleled flexibility and scalability, enabling organizations to adapt to varying workloads and demands. Each cloud provider excels in different areas, offering specialized features and technologies for specific tasks. For instance, one provider may be ideal for analytics services, while another may offer cost-effective data archiving. Businesses can leverage multicloud to match each workload with the most suitable technology and scale services up or down as needed without being locked into a single provider's ecosystem. This flexibility allows for tailoring services to the evolving needs of the business, a critical advantage in today's dynamic market.
- Cost-effectiveness: Multicloud strategies can lead to significant cost savings and operational efficiencies. Companies can select the most cost-effective services from various cloud providers across their operational areas. The increased competition among providers often results in better pricing models, such as pay-as-you-go, where businesses only pay for the services they actually use. Multicloud also helps avoid vendor lock-in, freeing companies from the obligation to subscribe to an entire suite of services from a single vendor. Instead, they can choose the best offerings from multiple sources, optimizing their IT spending.
