What Is Cloud Migration? Its Benefits, Strategy, Challenges & Approach

admin | January 8th, 2021 | Cloud, Migration

Cloud migration is the method of migrating your data — like emails, databases, applications, and IT processes — to a cloud platform from an on-premises environment or from one cloud to another. A cloud migration generally relates to migration tool and data from old, legacy infrastructure, on-premises to cloud suite.

There are different types of cloud migration an organization can perform. Most often cloud migration is considered as the process to transfer complete platforms from the on-premises data Center to a public or private cloud.

And another cloud migration model cloud is when migrating complete data from one cloud vendor to another — also known as cloud-to-cloud migration.

There is another kind which is reverse cloud migration, where data need to be migrated off from the cloud, i.e., migrating data from the cloud to the local data center (on-premise). However, this one is quite less referred to as cloud migration, rather they been referred to as cloud backup for on-premises.

Cloud Migration Guide: What it is, Why it’s Needed & How to do it?

A Brief Introduction to Cloud

The word “Cloud” in technology is often shorthand for ‘cloud computing’ – it refers to a group of computer applications running on the internet. This group of applications can be accessed on-demand or self-service.

With the cloud, data can be easily stored and accessible from anyplace, anytime in just a matter of time. Moreover, unlike on-premises, or local storage, storage facility can be increased or decreased in a few clicks.

In the above image, first we have enterprise infrastructure. This is typically where a lot of our compute workloads are bare metal, enterprise core systems, mainframe, on-premises data center. The middle one we have a private cloud over here, also on-premises, but cloud capabilities in full effect. And then we have public cloud, this is off-premises cloud capabilities.

Now, many of our enterprises are still struggling to get workloads off their enterprise infrastructure and on to the cloud. So, when we migrate enterprise workloads to private or public, we call that “migration”. And this is all about understanding enterprise workloads and their characteristics in terms of whether they should land on-premises cloud, or off-premises public cloud.

What are the Benefits of Cloud Migration?

At a basic level, the main goal or benefit of any cloud migration is for migrating their complete email suite data in the most powerful IT environment possible. It can be varied based on cost, performance, security, user-friendly application. For example, most of the organization switch to cloud from an on-premises environment for greater elasticity, efficiency, achieving the max results with the least expenditure, self-service provisioning, flexibility, and redundancy.

For ease of understanding, here, we will only focus on the target as the public cloud, though other cloud deployment models will also be having these benefits too. However, the general query of cloud migration comes from users that want to switch to the public cloud. Following are the 7 benefits of cloud migration:

  • Scalability and Business Elasticity
  • Cost Saving and Effectiveness
  • Flexibility and Agility
  • Reliability and Performance
  • Security and Compliance
  • Lesser Maintenance and Downtime

Best Cloud Migration Strategy

Migrating data to the cloud requires good planning and strategies. It includes choosing the right cloud platform, employee training, and successful data migration.

Though, there are many public cloud vendors are there the most demanding are of course Google and Microsoft cloud. They provide the best applications for their users and easy maintain. Moreover, most users already worked on their free email client, i.e., Gmail and MS Outlook for desktop. So, choosing among these two are the most recommended choices from experts.

Now, before proceeding with choosing the right migration technique, you should provide proper training to your employees. It helps them to easily continue the work once the new cloud suite is deployed completely.

Finally, the right data migration technique needs to be equipped for successful cloud migration. As not all migration technique provides 100% data migration. Choosing the right technique will help you to effortlessly migrate data to the cloud without any data loss.

Challenge Faced During Cloud Migration

Anticipating and analyzing issues during cloud migration is very crucial. Following are some of the challenges faced during cloud migration:

Cost Management — Apart from the cost of purchasing the cloud suite, the cost of data migration is also needed to be considered. There are many cloud migration tools and service providing companies out there, but only some of them provide 100% success. Moreover, some of the tools and services provides a limitation on the data that can be migrated using a license that cab increases the overall cost of the migration.

Complexity — If you are migrating from a different cloud suite, then you should know that no vendor provides an easy way out of their service. This makes migration quite complex. It restricts cloud migration tools and services providing companies to migrate complete data from the current suite to the new cloud platform.

Reskilling Employees – The most generally faced during cloud migration is reskilling of employees. Proper training needs to be provided to employees so that they can efficiently work on the new platform once deployed.

Downtime During Migration – Another common challenge during cloud migration is downtime. Most of the cloud migration tool and service providing companies requires no usage of accounts during the migration. Although it disrupts the working environment, it is necessary for errorless data migration.
