The Definitive Guide to Successful Cloud Migration

Quick Guide to Cloud Migration:

Cloud migration is like moving into a new house. You’re not just moving your stuff; you’re setting up for a better way of living. For businesses, that means more room to grow, better security, and saving money in the long run. But, just like moving homes, it can be a bit of a headache if not done right. You might worry about losing things or how much it’s going to cost.

In simple terms, cloud migration is taking all the digital parts of your business, like files and software, and moving them to the cloud. That’s an online space where everything can be stored safely and used anywhere. This can help your business in big ways—like cutting down costs because you don’t need to buy expensive hardware, or making it easier to handle more customers without slowing down your services.

But, there are some bumps along the way. You need to make sure your important information is safe during the move. You might also have to deal with your services being down for a bit while everything gets set up in its new cloud home. Plus, figuring out the cost can be tricky. It’s a big change, so feeling unsure is normal.

Understanding Cloud Migration

Transitioning to the cloud is like moving from a smaller home where you manage everything yourself to a large, managed residence where many of the chores and maintenance are taken care of for you. This section will simplify the concepts of cloud computing and various types of system migrations, helping you grasp the essence and benefits of moving to the cloud.

Cloud Computing

At its core, cloud computing is about renting processing power and storage from a service provider instead of owning and maintaining physical servers. You use the internet to access software, databases, and other services hosted remotely. It’s cost-effective, scalable, and flexible, allowing businesses to adjust resources according to their needs.

System Migration

System migration involves moving data, applications, or entire IT processes from one environment to another. It’s crucial for keeping pace with technological advancements and ensuring systems remain efficient, secure, and capable of meeting business demands.

Datacenter Migration

Moving from on-premises servers to a cloud provider’s servers is known as datacenter migration. Organizations opt for this to reduce IT costs, enhance performance, and eliminate the need for physical maintenance of servers. It involves transferring vast amounts of data, which can be challenging but is made easier with high-capacity networks or physical data transfer solutions.

Hybrid Cloud

A hybrid cloud strategy involves maintaining some resources on-premises (in a private cloud) while moving others to the public cloud. This approach offers flexibility, allowing businesses to keep sensitive data in-house while leveraging the cloud’s scalability for less critical data. It’s a middle ground that lets organizations gradually transition to the cloud and comply with regulatory requirements.

Cloud to Cloud Migration

With the proliferation of cloud services, many organizations now find themselves managing resources across multiple clouds. Cloud to cloud migration involves moving data and applications from one cloud platform to another. It’s often driven by the desire to optimize costs, performance, or to leverage specific services that are available on another platform. Despite seeming complex, central management tools make it easier to oversee resources across different clouds.

Understanding these fundamental concepts of cloud migration is the first step towards leveraging the cloud’s full potential for your business. Each type of migration offers unique advantages and challenges, but the overarching goal is to make your IT infrastructure more flexible, scalable, and cost-effective.

With this foundation, we’ll next explore the different phases of cloud migration, ensuring you have a roadmap for a smooth transition to the cloud.

Phases of Cloud Migration

Phase 1: Prepare

Before you even think about moving your data or applications, the first step is all about getting ready. This is where you lay the foundation for a successful cloud migration.

Phase 2: Plan

With a clear understanding of where you’re starting from and where you want to go, it’s time to plan how you’ll get there.

Phase 3: Migrate

Now, it’s time to start moving. This phase is where the action happens.

Phase 4: Operate and Optimize

Congratulations, you’ve made it to the cloud! But the work isn’t over yet.

Cloud migration isn’t a one-and-done deal. It’s a continuous process of improvement and optimization. As you settle into your new cloud environment, keep looking for ways to make your infrastructure work better for your business.

With these phases in mind, you’re well on your way to a successful cloud migration. Now, let’s dive into the different types of cloud migration to understand the various approaches you can take.

Types of Cloud Migration

When planning a cloud migration, understanding the types of migration is crucial. Each type has its benefits and challenges, and choosing the right one depends on your organization’s needs.


Also known as “Lift and Shift,” this approach involves moving applications and data to the cloud with minimal or no changes. It’s often the first step for businesses starting their cloud journey because it’s straightforward and fast. AWS is a popular choice for rehosting, offering a vast array of tools and services to simplify the process. Rehosting can be a cost-effective way to quickly gain the benefits of the cloud without investing in significant application modifications.


This approach takes rehosting a step further by making some optimizations to leverage cloud capabilities without changing the core architecture of the application. It’s like renovating a house to make it more energy-efficient without altering the structure. Azure is known for its platform services that facilitate this process, allowing businesses to improve performance and scalability while still keeping the migration process relatively simple.


Moving to a Software-as-a-Service (SaaS) model, such as adopting Office 365 for business productivity tools, falls under repurchasing. It means moving away from on-premise or self-managed applications to third-party cloud services. This approach can significantly reduce the complexity of managing IT infrastructure and software, but it requires organizations to adapt to the functionalities and limitations of the SaaS platforms.


Refactoring, or re-architecting, involves significant changes to an application’s architecture to fully embrace cloud-native features, such as scalability, elasticity, and performance. This method is often used for critical applications that require optimization for the cloud to meet specific business requirements. Technologies like Kubernetes support this approach by providing a platform for managing containerized applications in a highly automated and scalable way. While refactoring can be the most time-consuming and complex migration type, it offers the highest level of cloud optimization.


Decommissioning or retiring involves identifying IT assets that are no longer useful and can be turned off during the migration process. This step helps in cost savings and simplifies the IT portfolio by removing outdated and redundant applications.


Sometimes, it makes sense to keep some applications or systems where they are, either because they are too complex to migrate, not suitable for the cloud, or because of regulatory and compliance reasons. Retaining is about choosing to leave certain systems in the existing environment while still moving other parts to the cloud. It’s a strategic decision to ensure that each system is in the most appropriate environment.

By understanding these types of cloud migration, organizations can better plan their journey to the cloud, ensuring they choose the most suitable approach for each of their systems and applications. The key is to balance the benefits of the cloud with the unique needs and constraints of your business.

Next, we’ll explore the various strategies you can adopt to ensure a smooth transition to the cloud.

Cloud Migration Strategies

When planning your journey to the cloud, it’s vital to adopt a strategy that aligns with your business goals and IT infrastructure. Among the most recognized frameworks in cloud migration are the Gartner “5 Rs”, which have expanded into what some now refer to as the “7 Rs”. Additionally, cloud service providers like AWS and Azure offer specific programs designed to facilitate and optimize the migration process. Let’s break down these strategies and programs to help you navigate your cloud migration journey more effectively.

Gartner “5 Rs” Expanded to “7 Rs”

Gartner’s framework provides a comprehensive approach to evaluating and selecting the best migration strategy for your applications and workloads. Here’s a quick rundown:

  1. Rehost (Lift and Shift): This strategy involves moving applications to the cloud without making changes. It’s quick and cost-effective, making it ideal for businesses looking to migrate swiftly.

  2. Replatform (Lift, Tinker and Shift): Here, you make minimal adjustments to take advantage of cloud-native features without overhauling the entire application.

  3. Refactor/Re-architect: This more complex approach involves reimagining how an application is architected and developed, typically using cloud-native technologies, to achieve scalability and flexibility.

  4. Repurchase (Drop and Shop): Moving to a different product, often a SaaS platform, can sometimes be more efficient than moving the existing application as-is.

  5. Retain (Revisit): Some applications may not be ready or suitable for cloud migration, in which case they can be retained in the current environment, with plans to revisit the decision later.

  6. Retire: Identifying applications that are no longer useful and can be turned off will simplify the infrastructure and reduce costs.

  7. Relocate (Hypervisor-Level Lift and Shift): For VMware workloads, this means moving to a cloud environment without significant changes, facilitated by services like VMware Cloud on AWS.

Each of these strategies offers different benefits and challenges, and the right choice depends on your specific needs, resources, and timeline.

IaaS, such as AWS and Azure, provides you with the raw computing hardware – servers, networking technology, storage, and data center space – over the internet. It’s like renting a plot of land where you can build whatever you want, but you don’t own the land. You get the flexibility of managing your infrastructure without the cost and hassle of physical hardware. Yet, you maintain control over your operating systems, storage, and deployed applications.

PaaS (Platform as a Service)

Moving up the complexity scale, we have PaaS, represented by giants like Google Cloud and Oracle Cloud. PaaS provides you not just with the infrastructure but also with the software and development tools you need to build applications. It’s akin to renting a fully-equipped office space; you just need to bring your business idea and get to work. PaaS is ideal for developers who want to create applications without worrying about underlying infrastructure, allowing them to focus on the creative side of app development.

SaaS (Software as a Service)

At the top of the managed service model pyramid is SaaS, with familiar names like Salesforce and Slack. SaaS delivers fully functional, ready-to-use software directly to the user over the internet. It’s similar to subscribing to a service rather than owning it. With SaaS, you don’t worry about installation, maintenance, or updates; that’s all handled by the service provider. It’s perfect for businesses that want to hit the ground running with minimum fuss and maximum efficiency.

Which Model is Right for You?

Choosing between IaaS, PaaS, and SaaS depends on your organization’s needs, expertise, and the level of control you wish to maintain over your IT infrastructure.

Cloud migration isn’t just about moving to the cloud; it’s about transforming how your business operates. Each service model offers different benefits and levels of flexibility to help you achieve your goals. Whether you’re looking to offload the heavy lifting of infrastructure management, streamline app development, or simply adopt turnkey software solutions, there’s a cloud service model tailored for your needs.
