Many organizations are considering or have already begun migrating their workloads to the cloud. Studies show that a majority (80%) of organizations across the globe have adopted the cloud and are operating a hybrid model to cater to the recent technological ecosystem changes in 2022.
In 2019, there were 3% companies that had no plans for cloud migration, but that changed with COVID-19. Now, because of the countless benefits and the general flexibility that comes with the cloud almost every organization has a dedicated plan for migrating to the cloud.
Here is a graph to show the different cloud migration strategies organizations are looking to adopt across the globe and how it has changed from 2017 to 2022.
The cloud offers many benefits, such as increased agility, scalability, and cost savings. But migrating to the cloud can also be a complex process. This article will provide an overview of the key considerations for migrating to the cloud, including planning, execution, and post-migration.
The Fundamentals of Migrating to the Cloud – An Overview
When planning a cloud migration, it is important to first assess your current workloads and determine which are a good fit for the cloud. Not all workloads are suitable for migration, so it is important to carefully consider each one.
Once you have identified which workloads can be migrated, you will need to determine the most efficient way to migrate them. This will involve assessing your current infrastructure and determining how it can be adapted for use in the cloud.
You will also need to consider the data that needs to be migrated and how it can be securely transferred.
Executing a cloud migration can be a complex process, so it is important to have a well-defined plan in place. This plan should detail the steps that need to be taken, as well as who will be responsible for each step.
It is also important to have a backup plan in place in case of any unexpected issues. Once the migration is underway, it is important to monitor its progress and make sure that everything is going according to plan. After the migration is complete, there are a few things that need to be done to ensure a successful transition to the cloud. Three very important steps include:
- Updating your applications and systems for use in the cloud. This may require changes to your code or configuration.
- Ensuring that your data is secure in the cloud and that you have appropriate access control measures in place.
- Monitoring your cloud environment on an ongoing basis to ensure that it is running smoothly.
What Does it Mean to Migrate to the Cloud?
Cloud migration is the process of moving data, applications, and other business elements from an on-premises environment to a cloud computing platform. The major benefits of cloud migration include improved scalability, reduced costs, increased agility, and better disaster recovery.
In order to ensure a successful cloud migration, it is important to carefully plan and execute the migration process. This includes identifying which workloads and data should be migrated, assessing the risks involved, and selecting the right cloud platform. It is also important to have a good understanding of the differences between on-premises and cloud computing in order to make the most of the cloud platform.
There are two common approaches for cloud migration.
- The most common approach is to lift and shift, which involves simply moving the existing on-premises workloads and data to the cloud platform. This can be a quick and easy way to migrate, but it may not take full advantage of the cloud platform’s capabilities.
- The second approach is to refactor the workloads and data for the cloud. This involves redesigning the workloads and data to be more suitable for a cloud environment. This can take more time and effort, but it can improve performance and reduce costs.
The concept of cloud migration began with the advent of virtualization. Virtualization allows multiple virtual machines (VMs) to be run on a single physical server. This enables organizations to consolidate their servers and reduce their overall IT infrastructure costs.
Cloud migration takes virtualization one step further by moving VMs off of physical servers and into the cloud. The cloud is a network of remote servers that are accessed over the internet. Cloud providers offer various services, such as storage, networking, and computing power, which can be rented on a pay-as-you-go basis.
Benefits of Cloud Migration
There are many benefits to migrating workloads to the cloud. The main benefit is that it can help organizations to reduce their IT infrastructure costs, allows for better collaboration, and ensures better security.
Research suggests that the top driver for organizations shifting to a cloud-based IT infrastructure in the US is the security, data protection, and compliance benefits that the cloud offers , followed by data modernization and cost reduction.
Here is an overview of the benefits of cloud migration that managers seek.
Let’s take a closer look at these benefits.
Reduced IT Infrastructure Costs
One of the biggest benefits of migrating to the cloud is that it can reduce your IT infrastructure costs. Cloud providers typically charge on a pay-as-you-go basis, which can be much cheaper than buying and maintaining your own physical servers.
Furthermore, the cloud enables organizations to quickly provision new resources and scale their operations up or down as needed. This can save you money by avoiding the need to overprovision for peak demand.
The cloud enables organizations to quickly provision new resources and scale their operations up or down as needed. This can be a big advantage in today’s fast-paced business environment. This means that the cloud enables organizations to be more flexible in how they use their resources, risks, and opportunities.
For example, you can easily provision new resources for a project and then release them when the project is finished. This can save you time and money by avoiding the need to purchase and maintain extra capacity.
Improved Disaster Recovery
In the event of a disaster, you can quickly spin up new resources in the cloud and keep your business running. The cloud helps here by enabling your organization to quickly provision new resources in the event of a disaster.
This can help you avoid downtime and keep your business running smoothly. It is important to note that the cloud makes it easy to replicate data and applications across multiple locations and therefore create better, more reliable backups.
This can protect your data from being lost or corrupted if one location is damaged or destroyed.

Key Cloud Migration Strategies
There are four primary cloud migration strategies that you can adopt, based on the infrastructure you are looking for. These include:
Public Cloud Migration
Public cloud migration is the process of moving data and applications from on-premises to a public cloud provider, such as AWS, Azure, or Google Cloud. This strategy can offer a number of benefits, including increased flexibility and scalability.
The public cloud offers a number of advantages over on-premises systems, such as;
- Public clouds are designed to be highly scalable. This means that you can easily add or remove resources as your needs change.
- More cost-effective than on-premises systems. This is because you only pay for the resources you use.
- Increased flexibility. This means that you can easily change your IT resources as your needs change.
Private Cloud Migration
Private cloud migration is the process of moving data and applications from on-premises to a private cloud. You should consider this strategy if you are looking for increased security and compliance without worrying about the costs.
The private cloud offers a number of advantages, such as:
- More secure than public clouds. This is because private clouds offer increased control over who has access to your data and applications.
- Improved compliance. This is because private clouds can be configured to meet specific regulatory requirements.
- Better privacy and access control features.
Hybrid Cloud Migration
Hybrid cloud migration is the process of moving data and applications from on-premises to a hybrid cloud environment, i.e., the cloud plus on-premise solution. This strategy can offer a number of benefits, including increased flexibility and scalability.
- Hybrid clouds are designed to be highly scalable, allowing you to easily add or remove resources as your needs change.
- Hybrid clouds are typically more cost-effective than on-premises systems or complete cloud solutions.
- They offer more control to you and better protection against uncertainties.
Multicloud migration is the process of moving data and applications from one cloud environment to another completely on its part. The most prominent benefit therein is the portability you get and access to more features across different cloud hosts.
- Multiclouds are designed to be highly scalable and versatile, thanks to the numerous clouds you use and their base features.
- There is a risk of overlapping costs or features if you do not choose the new cloud properly and hence introduce inefficiencies. However, chosen correctly, the decision can be a very cost-effective one.
- Multicloud migration strategy blends the features, applications, and services of two or more clouds into a single solution.
Migrating to the cloud can offer a number of benefits, including increased flexibility, scalability, and cost-effectiveness. However, it’s important to choose the right migration strategy for your business. As the world evolved, the cloud is now the new way of doing business.
Organizations need to adapt to the transformed ecosystem and cloud migration is the perfect technique to do so.
