Understanding Cloud Migration

When we talk about cloud migration, we’re essentially referring to the process where businesses move their digital assets — think applications, data, and IT processes — from their current on-premises hardware to the cloud. It can also mean moving from one cloud platform to another. This shift not only marks a significant change in how IT resources are managed but also offers a new realm of possibilities for businesses in terms of scalability, efficiency, and innovation.

Cloud Migration Definition

At its core, cloud migration is like relocating from a traditional house to a modern, fully-serviced apartment. Your old house (on-premises IT infrastructure) requires constant upkeep, from fixing the plumbing to managing the electricity. The new apartment (cloud environment), however, offers these services as part of your rent, taking the maintenance burden off your shoulders and providing more amenities (services and technologies) than you had before.

Types of Cloud Migration

There are several paths you can take when migrating to the cloud, each with its own set of strategies including:

  • Rehosting: Often referred to as “lift and shift,” this strategy involves moving your applications to the cloud with little to no modifications. It’s quick and cost-effective.
  • Replatforming: This involves making minor adjustments to your applications to optimize them for the cloud, without changing the core architecture.
  • Refactoring/Re-architecting: This is the most complex approach, where you redesign your application to be cloud-native, taking full advantage of cloud technologies and services.
  • Repurchasing: Moving to a different product, often a cloud-based version of an enterprise software.
  • Retiring: Identifying IT assets that are no longer useful and decommissioning them to save costs.
  • Retaining: Keeping certain elements of your IT infrastructure on-premises or in the original cloud environment.

Benefits of Migrating to the Cloud

The benefits of moving to the cloud are many, including:

  • Scalability: The cloud provides the ability to scale your IT resources up or down based on demand, ensuring you’re not paying for unused capacity.
  • Cost Efficiency: With the cloud, you often pay only for what you use, which can significantly reduce costs associated with managing and maintaining IT systems.
  • Security: Many cloud providers offer robust security features that can be more comprehensive than what a single organization can implement.
  • Performance: Cloud providers invest in the latest technologies to ensure high performance, which can be beneficial for businesses looking to optimize their operations.
  • Sustainability: By leveraging the cloud’s shared resources, businesses can reduce their carbon footprint and contribute to sustainability efforts.

In summary, cloud migration is a transformative process that offers a multitude of benefits but requires careful planning and execution. Understanding the types of cloud migration and the potential benefits can help businesses make informed decisions and navigate their journey to the cloud more effectively.

We’ll explore the preparatory steps businesses should take to ensure a smooth and successful migration to the cloud.

Preparing for Cloud Migration

Before diving into the cloud migration process, lay the groundwork. Preparation is key to a successful migration, ensuring that the transition is not only smooth but also aligns with your business goals and technical requirements. Let’s break down the preparation process into manageable steps.


First things first, you need to understand what you’re working with. This means taking a comprehensive inventory of your current IT infrastructure. Identify every application, workload, and piece of data that you currently manage. Understand how these elements interact with each other and the implications of moving them to the cloud.

Business Objectives

Why are you considering migrating to the cloud in the first place? Is it for scalability, cost efficiency, performance improvement, or maybe all of the above? Clearly define your business objectives. This will not only guide your migration strategy but also help you measure success post-migration.

Technical Requirements

Every business has unique technical needs. Maybe your applications require high computational power, or perhaps data security is your top priority. List down all technical requirements your cloud environment needs to fulfill. This will help you choose the right cloud service provider and migration strategy later on.

Cost Estimation

Let’s talk numbers. Migrating to the cloud can lead to significant cost savings in the long run, but it requires an initial investment. Use cloud cost calculators to estimate future costs and compare them with your current expenses. Consider both direct costs (like storage and compute resources) and indirect costs (such as team training and potential downtime during migration).


Not everything needs to move to the cloud at once. Prioritize your applications and workloads based on their importance to your business and their readiness for migration. Some might benefit from a quick “lift-and-shift” approach, while others may require significant refactoring. Start with less complex, non-critical systems to gain momentum and learn from the experience.

Preparation is more than just a preliminary step; it’s a foundation for your cloud migration journey. By thoroughly assessing your current state, defining clear business objectives, understanding technical needs, estimating costs, and prioritizing migration activities, you set yourself up for a successful transition to the cloud.

As you gear up for this exciting journey, keep in mind that cloud migration is not a destination but a path to transforming your business for the better.

Next, we’ll dive into the various cloud migration strategies and how to choose the right one for your needs.

Cloud Migration Strategies

When it comes to moving your business to the cloud, there isn’t a one-size-fits-all strategy. The right approach for your organization depends on your specific needs, goals, and existing infrastructure. Let’s break down the different cloud migration strategies available, so you can make an informed decision about which path is best for you.

Rehosting (Lift and Shift)

Imagine picking up a plant from a small pot and putting it into a bigger one. That’s rehosting. You take your existing applications and move them to the cloud with little to no changes. This method is fast and cost-effective, making it a popular first step for businesses new to cloud migration.

Relocating (Lift and Optimize)

Relocating is like rehosting, but once your applications are in the cloud, you start making small improvements. For example, you might switch to a cloud database service to enhance performance without redesigning your whole application. It’s a middle ground that offers some cloud benefits with minimal effort.

Refactoring (Re-architecting)

Refactoring is the most intensive approach. It involves reimagining how an application is built to fully take advantage of cloud features, like scalability and flexibility. This strategy is typically chosen for critical applications that need significant improvements in areas like performance or scalability.

Replatforming (Lift, Tinker, and Shift)

Replatforming means making a few more changes than relocating to take advantage of the cloud. It might involve using cloud-native services for certain application components. It’s about finding a balance between not changing much and changing enough to gain substantial benefits.

Repurchasing (Move to SaaS)

Repurchasing involves moving to a different product altogether, often a Software-as-a-Service (SaaS) solution. It’s like deciding to stop cooking at home and start dining out. You might switch from an on-premise CRM to a cloud-based service like Salesforce. This strategy can significantly reduce the complexity of managing IT infrastructure.


After evaluating your applications, you might find some that are no longer needed. Turning these off can save costs and simplify your IT landscape. Think of it as decluttering your home of things you no longer use.

Retaining (Do Nothing, For Now)

Sometimes, the best strategy is to wait. You might choose to keep certain applications as they are, either because they’re too complex to migrate now or because they don’t have a clear business case for moving to the cloud. It’s okay to revisit these decisions later.

Choosing the Right Cloud Provider

Once you’ve decided on a strategy, you’ll need to choose a cloud provider. The big players are AWS, Google Cloud, and Microsoft Azure. Each has its strengths and offers a range of services to support different migration strategies. Your choice might depend on specific features, pricing, or existing relationships.

  • AWS is known for its extensive service offerings and strong support for rehosting and replatforming strategies.
  • Google Cloud shines with its data analytics, machine learning capabilities, and strength in containerization, which is great for refactoring.
  • Microsoft Azure offers seamless integration with Microsoft products, making it an attractive option for businesses heavily invested in the Microsoft ecosystem.
