What is Cloud Migration? | Benefits, Process & Types
Published: 2024-03-22 22:58:30

With enterprises rapidly adopting cloud solutions, migrating to the cloud has become a strategic priority. But for many companies, tiny and midsized businesses, the process of cloud migration remains shrouded in some mystery. This article clears the fog by explaining what cloud migration entails, its manifold benefits, the step-by-step migration process, and different types of cloud migrations.

## What is Cloud Migration?

Cloud migration refers to moving an organization's data, applications, or other business elements from on-premises computers or legacy infrastructure to a cloud-based environment. Rather than managing their physical servers, companies can leverage the infrastructure of public cloud providers like AWS, Azure, and Google Cloud Platform to host their workloads. This shift allows businesses to trade upfront capital expenditure for flexible pay-as-you-go operating expenditure models. To transfer all this correctly, businesses turn to [cloud migration services](https://modlogix.com/services/cloud-migration/) or outsource this task.

## Benefits of Migrating to the Cloud

Migrating to the cloud powered by cloud computing technologies brings several valuable advantages:

1. Improved collaboration. Cloud fosters real-time, location-independent collaboration.
2. Enhanced security. Leverage advanced cloud security versus managing yourself.
3. Operational efficiency. Cloud automation liberates IT teams from maintenance duties.
4. Insights from data. Cloud analytics spot impactful insights within data.
5. Reduced costs. Significant savings were realized from escaping expensive private data center models.
6. Flexibility. Scale cloud capacity up and down to align with evolving needs.

## Types of Cloud Migration Strategies

Companies can choose between several forms of cloud migration with different mechanisms for shifting data:

1. Database migration – moving databases or storage to cloud-based equivalents.
2. Disaster recovery migration – replicating on-premises apps and data to cloud.
3. Lift and shift migration – physically transferring existing infrastructure to the cloud.
4. Application migration/modernization – re-architecting apps to leverage cloud-native services.

## The Process of Cloud Migration

Migrating an entire organizational IT infrastructure to the cloud is an intricate process best tackled through a systematic approach:

###  Ascertain the Purpose of Your Cloud Migration
To choose the best platform that offers all the cloud features you want, you must first clearly define your cloud migration strategy's goals and objectives. To demonstrate that the cloud strategy is giving your business the advantages it wants, you need also to decide the cloud migration KPIs you will be tracking.

### Establish a Budget
Although moving to the cloud might save you money, depending on how much and how sensitively you need to migrate your data, the process of migrating it to the cloud can often be just as expensive as the cloud storage itself. As such, it's critical to include the cost of the migration process itself when creating your budget and to consider this when choosing a cloud partner.

### Select the Destination(s) for Your Cloud Transfer
When selecting a partner, you should take into account more than just the cost of the cloud; you should also take price, security, growth potential, and other aspects into account. You must contemplate whether a public, hybrid, or private cloud solution would be more advantageous for your organization.

### Redesign your Program's Architecture
It may sometimes be necessary to modify your on-premises apps to enable them to function with the cloud infrastructure. This might include containerizing the application, modularizing the code so that portions can remain on-site, virtualizing the application by running it on a virtual machine (VM) or refracting the code to make use of certain cloud capabilities. 

###  Take into Account Using Technologies for Data Transfer
When it comes to carrying out a successful migration procedure, you are not alone: [AWS Migration Hub](https://www.applytosupply.digitalmarketplace.service.gov.uk/g-cloud/services/941508099303265) is just one example of the native products from many cloud providers that may assist you in importing your on-premises apps into the cloud. If the native tools don't work well for you, you may alternatively utilize a third-party solution like Cloudsfer, AWS Database Migration Service, Azure Migrate, or Google Cloud Migrate to Virtual Machines.

### Decide on a Transfer Strategy
You must also plan the actual transfer of your data from your present hardware or cloud provider to your new cloud environment to have a successful cloud migration procedure. There are trade-offs between public internet, private/dedicated networks, and physical transfers; these alternatives are limited in terms of speed, duration, cost, and security. 

### Create a Strategy for Cloud Migration
After completing the above-mentioned choices, you are prepared to create a strategy for your cloud migration project that specifies the data that will be moved and in what sequence. It's critical. 

Notify your present clients of the impending move and any potential service interruptions as soon as the dates are set.

### Begin with a Little Migration
You never migrate all of your data at once when moving to the cloud. Instead, move a tiny amount of non-essential data or an app to the cloud, test it, and make sure everything moves correctly. If there are any issues, fix them and run the test once again. Don't go on with a larger-scale migration procedure until all the bugs are ironed out.

### Finish the Data Transfer
It's time to move all of your on-premises applications onto the cloud once you've verified that your application migration procedure is effective and error-free. After the migration is finished, double-check everything to make sure everything is transferred securely. Savor the benefits of using your new cloud solution and all of its features.

## Bottom Line

Migrating business functions to the cloud marks a landmark leap no longer confined to early adopters. With cloud transformation becoming inevitable across industries, companies must continue self-education efforts to dispel lingering mysteries about implementation hurdles.
