Exploring Different Types Of Cloud Migration Strategy


Cloud migration is an increasingly important topic for businesses of all sizes. As cloud technology becomes more powerful, cost-efficient, and widely accepted as the best choice for IT infrastructure, organizations are turning to cloud migrations as a way to improve their operations. But what are the different types of cloud migration strategies? In this blog post, we’ll explore the various approaches to cloud migration and the characteristics of each. We’ll also discuss the challenges that come with migrating applications and workloads to the cloud and what organizations should consider when making their decision. By the end of this post, you should have a better understanding of the different types of cloud migrations available and be able to make an informed decision. Let’s get started! 


Defined Cloud Migration Strategy 

An organization’s high-level plan for moving its current on-premises and/or co-located application workloads and the data they generate into the cloud is known as a cloud migration strategy. The majority of plans contain a strategy for moving to a public cloud provider, such as Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, or another. Not all workloads are appropriate for migration, even if the majority of workloads will benefit from cloud migrations. 


Prioritizing workloads for migration and choosing the best migration technique for each one are essential components of a successful enterprise cloud migration strategy. The strategy will also be tested in a pilot and adjusted based on the outcomes of the pilot. To lead teams through the procedure and enable roll-back if necessary, a cloud migration strategy document should also be prepared. 


The ideal outcome is a smooth migration of the applications from the current on-premises infrastructure to the required cloud architecture without interfering with application availability or regular business activities.


Why Should We Apply A Cloud Migration Strategy? 

A cloud migration strategy can provide immense insight for transitioning from on-premises to the cloud. It enables organizations to identify which application workloads should be continued, rewritten, or replaced – and also evaluates suitable target clouds for each one. As such, enterprises stand to benefit immensely by combining various approaches included in a comprehensive enterprise cloud migration plan into their operations – reducing costs while minimizing disruption at the same time.

Types Of Cloud Migration Strategy – The 6 R’s 

Generally, there are 6 most common cloud migration strategies


1/ Re-host (lift-and-shift) 

Re-host is a fundamental tactic that entails moving the content you now host on-premises to the cloud. You transfer a precise duplicate of your current environment to a cloud environment of the same kind. Usually, this tactic does not necessitate major architectural alterations or reconfigurations. When hosted in the cloud, everything that functioned in the on-premise environment should continue to function in the same way.


2/ Re-platform 

Re-platform is a cutting-edge approach to cloud migration that takes lift & shift further. It gives developers the opportunity to optimize applications, so they perform faster and better in their new environment – while ensuring total integration with the cloud’s architecture. With re-architecture comes an added level of complexity: programming expertise is essential for successful transition. 


3/ Repurchase 

Repurchase provides an opportunity to shift your work environment into the cloud. Yet, while this allows you to replace legacy applications with SaaS solutions, it presents a challenge: team members must be retrained and become familiarized on the new platform – not something easily done. Apart from that, moving licenses from local servers to cloud-based servers is an alternative course of action for the repurchase strategy. 


4/ Retain 

At this time, if a full-fledged migration to the cloud does not fit your company’s needs, there is always the option of opting for hybrid solutions; preserving part of your infrastructure onsite while allowing certain components to be hosted in the cloud environments. This can certainly accommodate you when revisiting an eventual move into the cloud at a later stage. 


5/ Retire 

If you don’t see any value in a certain application or service for your customers, there’s no need to keep it around. It might be wise to simply turn it off instead of wasting time and resources migrating it into the cloud. 


6/ Re-factor 

To keep up with future technology developments, businesses could also consider re-factoring existing applications. By investing the time and resources needed to redesign their applications for a cloud environment, they can secure compatibility with rising innovations while improving accessibility in anticipation of potential growth. 


Challenges Of A Cloud Migration Strategy 

Organizations on their path to the public cloud need an intentional strategy that considers workloads, infrastructure and operations. Without careful consideration of these components, migrations may lead to failure or delays; working with development teams is often necessary for a successful transition. 

When making the transition to cloud infrastructure, it’s also important to plan for how legacy servers and applications will be managed. Certain applications might lend themselves well towards migration – but others may not fit so easily into a new environment. Careful consideration should also go into what happens when hardware has reached its end-of-life, as this can have an impact on data center space optimization plans. 


In general, there are 3 critical factors that an organization has to pay attention to when implementing a cloud migration strategy: 

+ Security: Security remains a top priority in migrating to the cloud. Companies need to ensure that their applications and data remain safe, while meeting any compliance requirements they may have. 

+ Governance and Compliance: By region and sector, regulations change significantly. The storage of an organization’s data in the cloud can be physically safe, but the cloud client is still responsible for making sure that legal requirements for data privacy and retention are met. 

+ Cost Management: Keep the cloud clean and organized – de-provision unused accounts, workloads, and data to reduce wasted resources from applications being duplicated needlessly. This helps avoid costly cloud sprawl by staying ahead of resource consumption. 



In conclusion, cloud migration is a complex process that requires careful planning and execution. Companies must carefully consider their workloads, infrastructure, and operations in order to ensure a smooth transition. With the right strategy and an understanding of security, governance and compliance requirements, as well as cost management considerations, organizations can leverage the power of the cloud with confidence.
