Cloud migration involves moving data, applications, and computing resources from your data center to cloud providers. It’s like moving to a place with lower costs, more capabilities, frequent tech updates, and endless scalability. This shift aims to reduce the need to hire experts to manage hardware and software. However, the process can be challenging and risky if not planned well. This guide helps you understand the essentials of cloud migration planning and prepares you for a successful move to a better digital setup.
What is Cloud Migration?
Cloud migration refers to moving digital assets, such as data, applications, and workloads, from an on-premises environment to a cloud computing environment. This transition typically involves transferring data and applications to a cloud service provider’s infrastructure, where they can be stored, managed, and accessed remotely over the internet. It requires extensive planning and preparation but often pays off with cost savings and more flexibility.
Usually, “cloud migration” means moving from old-school systems to the cloud, but it can also mean switching between different cloud services.
Why Migrate to the Cloud?
Are you thinking about moving to the cloud? It’s a big deal for businesses! Imagine adjusting to busy times quickly, saving money on hardware, and keeping your data safe. Plus, your team can work together efficiently from anywhere. Let’s discuss and see how it can make a real difference for you!
Migrating to the cloud offers significant advantages, such as cost reduction and infrastructure optimization. Organizations can reduce costs related to owning, operating, maintaining, and updating equipment in on-premises data centers by transitioning from a capital expenditure model to an operational expenditure model.
Moreover, cloud migration enhances company performance and uptime, facilitating workload modernization and eliminating costly licensing fees from outdated applications. It also strengthens data security, enhances governance, and ensures compliance with global regulatory standards.
What Are the Types of Cloud Migration?
The three primary types of cloud migration include:
- Complete data center conversion
- Transfer of support for business process software
- Optimization of web/mobile applications
Complete data center conversion represents the most intricate and time-intensive form of cloud migration. In this model, businesses, NGOs, or government agencies aim to shift all their data center hardware to a public cloud provider. This encompasses software supporting various functions such as customer orders, shipping, logistics, manufacturing, and industrial production.
Complete data center conversion involves migrating internal and external business processes from an on-premises or private cloud to a public cloud architecture. The complexity involved often prompts companies to adopt hybrid and multi-cloud strategies for daily operations
Some enterprises migrate only a portion of their IT resources, software, or databases to a public cloud provider while maintaining private cloud infrastructure and complex networking to support internal activities. Many corporate security policies prohibit mission-critical data from being hosted by third parties off-premises.
Likewise, numerous businesses find remote desktop hardware essential for daily operations. Hybrid or multi-cloud approaches involve outsourcing public-facing web services to cloud providers to enhance efficiency and reduce costs while retaining internal services like legacy databases and CRMs locally managed by corporate IT departments.
The most straightforward type of cloud migration involves moving a limited set of web or mobile applications to a public cloud architecture for hosting and DevOps management. Public cloud providers offer numerous platform tools for programmers, web developers, and system administrators, improving the efficiency of the software development lifecycle.
Enterprise software development teams must adopt continuous integration and continuous delivery (CI/CD) practices, testing code across multiple programmers through sandboxes and version control. All major public cloud providers offer software tools facilitating the transfer of databases and software application resources to remote hardware.

The Cloud Migration Process
The cloud migration process typically involves several essential steps for a seamless shift from on-premises infrastructure to cloud-based services. Here are the fundamental steps:
Assessment and Planning: Assess the existing IT infrastructure, applications, and data to identify which elements suit migration to the cloud. Identify dependencies, performance requirements, and potential risks.
Selecting the Ideal Cloud Provider: Choose a cloud service provider (CSP) that aligns with your unique requirements, such as AWS, Azure, Google Cloud, or other options. Evaluate pricing, available services, compliance needs, and support availability.
Designing the Cloud Architecture: Create a blueprint detailing how applications, data, and services will be migrated. Define network configurations, security policies, and data management strategies.
Data Migration: Transfer existing data to the cloud, ensuring minimal downtime and data integrity. Use tools and methodologies aligned with your migration strategies, which we’ll explore further in this article.
Application Migration: Transition applications to the cloud, considering compatibility, performance needs, and dependencies. Adapt applications as necessary for cloud environments.
Testing and Validation: Ensure thorough testing is conducted to verify the seamless functionality of migrated applications and data within the cloud environment. Validate performance, security, and functionality against predefined metrics.
What Cloud Migration Strategies Should Enterprises Adopt?
There are seven cloud migration strategies: rehosting, redeployment, repackaging, refactoring, repurchasing, retiring, and retaining. Initially termed the ‘5 Rs’ by Gartner, this framework expanded to the ‘7 Rs’. Organizations migrating to the cloud should evaluate these strategies to determine the most suitable approach. Below is a concise overview of each strategy:
Refactor/Re-architect: Transform an application by redesigning its architecture to leverage cloud-native features, enhancing agility, performance, and scalability. This often involves migrating the operating system and database.
Replatform (Lift and Reshape): Migrate an application to the cloud while optimizing it to utilize cloud capabilities effectively
Repurchase (Drop and Shop): Transition to another product, typically adopting a Software-as-a-Service (SaaS) model instead of traditional licensing.
Rehost (Lift and Shift): Move an application to the cloud without modifying its architecture, primarily to achieve cloud benefits like scalability and reduced infrastructure management.
Relocate: Shift infrastructure to the cloud using technologies like VMware Cloud without requiring new hardware or significant changes to existing applications.
Retain: Maintain applications in their current environment, potentially deferring migration due to significant refactoring needs or because they serve their purpose adequately.
Retire: Discontinue or remove applications no longer needed in their current environment.
Which Cloud Deployment Style is Optimal for Companies to Select?
Companies’ optimal cloud deployment style depends on various factors, such as their specific needs, existing infrastructure, and strategic goals. Here are some standard cloud deployment models and their suitability:
- Public Cloud: Ideal for scalability, cost-efficiency, and accessibility. It’s suitable for applications with variable workloads that benefit from offloading IT management.
- Private Cloud: Offers enhanced security, control, and customization. It’s preferred for sensitive data, compliance requirements, and applications needing dedicated resources.
- Hybrid Cloud: Integrates features from both public and private clouds, offering flexibility and workload optimization. It suits businesses with varying workload demands, regulatory requirements, or legacy systems.
- Multi-Cloud: Involves using services from multiple cloud providers to avoid vendor lock-in, optimize performance, and leverage specialized services. It’s beneficial for redundancy, disaster recovery, and accessing best-of-breed solutions.
