The Essential Guide to Cloud Migration
Benefits, costs, strategies, and more — everything you need to make the leap to the cloud
Staring down the barrel of a big cloud migration project? You’re not alone. According to Splunk and Harvard Business Review, 67% of senior executives said their companies have accelerated cloud adoption. And while essentially all organizations depend on cloud computing to some degree, most are feeling the pressure to move even more of their IT architecture onto the cloud.
As a result, it’s become essential for companies to have an in-depth understanding of the cloud migration process. From basic concepts to the finer points of each strategy, here’s what your organization needs to know to transition successfully.

What Is Cloud Migration?
Cloud migration is the process of transitioning part or all of an organization’s IT architecture from an on premises or previous cloud environment to a new cloud environment. Cloud migrations can cover every element of the tech stack, including data, workloads, applications, servers, and beyond. To ensure they can successfully navigate this complex process, many companies invest in risk mitigation tactics such as developing a cloud migration project plan, using cloud migration tools, and hiring experienced cloud migration consultants.
One of the most effective tactics is using automation to accelerate the cloud migration process. Some automation solutions, like DuploCloud, help organizations cut the time and money required to transition by as much as 80%.

What Are the Benefits of Cloud Migration?
There’s a reason why Garter forecasted global public-cloud spending to hit $500B by the end of 2022: Cloud-based IT has numerous advantages. These benefits include greater flexibility, lower costs, enhanced performance, automated compliance, and simplified resource management.
- Greater flexibility: Cloud IT architecture is significantly more scalable and agile than on premises assets, allowing IT teams to rapidly spin up or down resources according to an organization’s evolving needs.
- Lower costs: With cloud IT architecture, organizations only need to pay for the storage and applications they actually use — minimizing spending. On premises assets, on the other hand, are an ongoing expense unless decommissioned.
- Enhanced performance: Cloud IT architecture allows organizations to split storage and processing across multiple resources, improving speed and reducing downtime.

What Are the Costs Involved in the Cloud Migration Process?
As beneficial as many companies find transitioning to the cloud, the process does necessitate some new expenses. Here are a few of the costs any migration plan should account for:
- Refactoring: Replicating your tech stack in the cloud can be expensive, especially if your architecture is highly customized. To ensure you don’t get caught off guard, do an in-depth assessment of the complexity of your existing IT systems.
- Hosting: Each major cloud service provider (CSP) has a broad set of pricing options that vary depending on your needs, from storage requirements to data request volume. Doing an assessment — this time of your projected usage — will help you get a handle on your hosting expenses.

What Are the Best Cloud Migration Strategies?
Cloud migration strategies are an integral part of any cloud migration plan. These strategies help organizations determine how to approach the transition process across their on premises assets — piece by piece.
- Rehosting: Also known as “lift and shift,” rehosting entails directly transferring legacy, on-premises applications to the cloud. While this approach is quick and cost-effective, there are long-term drawbacks: The new cloud applications are not optimized for the new environment and won’t have any more features.
- Repackaging: This strategy also falls within the “lift-and-shift” category, but it adds a bit more to the process. Instead of essentially dropping an old application into the cloud as-is, repackaging involves doing some customization work to the code to enhance performance in the new environment. This approach takes longer than rehosting, but it also improves results over the long run.
