What are the Primary Cloud Migration Techniques?

Cloud migration has gained popularity for its obvious traction and proven benefits in the marketplace. A successful migration technique should address organizational goals such as decreasing hosting costs and improved alignment between business objectives and IT solutions. It also allows businesses to move at the speed of the market, get closer to their customers, and focus their attention on innovation.

Cloud Migration Techniques

Many companies don’t want to be left behind, but they often don’t have well-structured plans to execute a successful cloud migration. Cloud migration is a complex process that must be well modified to address the needs of a company. We have identified the primary cloud migration techniques businesses use to accomplish their goals.

Rehost (Lift and Shift)

Primary Cloud Migration Techniques Rehost

This is a popular cloud migration technique known as “lift and shift.” It involves moving an existing on-premises IT infrastructure to the cloud with the architecture of the previous workload running on infrastructure as a service (IaaS).

This migration technique transfers the exact copy of the three layers: database, OS, and application layer. It enables a rapid, minimal disruption and cost-effective cloud migration. However, because of this same reason, an organization may not take full advantage of the cloud.

Lift-and-shift migration can cost more than other techniques in the long run due to the lack of vital features and optimization for APIs, affecting opportunity costs and excessive operating expenses on unoptimized workloads. Companies that succeed with cloud migration either go beyond rehosting techniques or find a practically identical platform regardless of the environment with rehosting as efficient as it is expedient.


Primary Cloud Migration Techniques Replatform

Replatforming involves further adjustment to lift and shift to improve the business landscape in the cloud. With this technique, organizations can leverage significant cloud benefits such as tuning applications, functionality, and better cloud compatibility as the company reshapes its sourcing environment, eventually helping avoid post-migration work. Replatforming includes configuring APIs, optimizing the operating system, middleware upgrades, and using platform-as-a-service (PaaS) solutions

As with rehosting migration techniques, re-platforming keeps core architecture intact. This is a good strategy for conventional organizations looking to build trust in the cloud environment while attaining benefits such as increased system performance. While it is a conservation migration technique, it can exploit the power of cloud computing services more than the regular lift and shift. However, this technique is hard to implement, as it requires maximum planning and the most upfront cost.


Refactoring cloud migration techniques requires making significant changes to a company’s application or workload. This cloud migration technique is driven by a great need to add new and valuable features, scale, or improve performance that would be challenging to accomplish in the existing environment. These additions might be difficult or impossible to implement with rehosting or re-platforming techniques, so refactoring offers cost benefits.

Since the refactoring technique consists of massive changes, it is more resource-consuming and expensive than rehosting and re-platforming migration techniques. However, because the workload can be adapted to fit the cloud, the benefits of refactoring can also be considerable.

Other Cloud Migration Possibilities

During the cloud migration process, it may become evident that the workload is not suited to the cloud or is no longer required. These findings are often characterized as forms of cloud migration, including replacing, retiring, or retaining. For instance, a legacy application might be replaced with SaaS equipment. Equally, on-premises applications can stay on-premises and connected to a hybrid-cloud computing environment.

The technology landscape continues to change, and more organizations will look to a cloud-based solution to support healthy operations and achieve their goals. Moving to the cloud has endless benefits over maintaining and replacing outdated hardware and data centers.

Cloud migration is a great solution, but organizations must weigh their options to determine the best course of action.
