What is Cloud Migration? Benefits of Moving to the Cloud

Cloud Computing is one of the most implemented methods for developing and delivering enterprise applications currently. It is also the most opted solution for the ever-expanding needs of SMEs and large scale enterprises alike.

As businesses grow and their process technologies improve, there is a growing trend towards companies migrating to the cloud. This process of moving services and applications to the cloud is the basic definition of Cloud Migration. The enthusiasm that companies have towards cloud migration is evident in the massive amounts of money and resources they dedicate to improve their operations.

In this article, we will introduce Cloud Migration processes and different ways of adapting to your organizational structure.


What is Cloud Computing?


Before tackling the question of “What is Cloud Migration?” let’s define Cloud Computing.

Cloud Computing is an enhanced IT service model that provides services over the Internet. Scalable and virtual resources like servers, data storage, networking, and software are just some examples of these services. Cloud computing can also mean running workloads in a provider’s powerful data centers and on servers for a price.

Cloud Computing is considered one of the cutting edge technologies of the 21st century. Its innovative ability to provide relatively inexpensive and convenient networking and processing resources has fueled wide-ranging adaptation in the computing world.

The Cloud Migration process is an inevitable outcome of Cloud Computing. It has revolutionized the business world by facilitating easy access to data and software through any IoT (internet-connected) device. Moreover, it facilitates parts of the SDLC (Software Development Life Cycle), such as development and testing, without any consideration for physical infrastructure.


What is Cloud Migration?


Cloud Migration is simply the adoption of cloud computing. It is the process of transferring data, application code, and other technology-related business processes from an on-premise or legacy infrastructure to the cloud environment.

Cloud Migration is a phenomenal transformation in the business information system domain as it provides adequate services for the growing needs of businesses. However, moving data to the cloud requires preparation and planning in deciding on an approach.

The other use-case for Cloud Migration is cloud to cloud transfer.



Types of Cloud Migration


The process of Cloud Migration creates a great deal of concern in the business and corporate world who have to prepare for many contingencies that come along with it. The type and degree of migration may differ from one organization to another. While certain organizations may opt for a complete migration, others may do so in part with still others remain on-premises. Some process-heavy organizations may require more than one cloud service.

In addition to the degree of adoption, other parameters categorize Cloud Migration. These are some of the more commonly seen use-cases.


Lift and Shift


This process involves moving software from on-premise resources to the cloud without any changes in the application or a process used before. It is the fastest type of cloud migration available and involves fewer work disruptions since it involves only infrastructure, information, and security teams. Furthermore, it is more cost-effective compared to other methods available.

The only downside to this method is that it does not maximize the advantages of the performance and the versatility of the cloud as it involves only moving the application to a new location. Therefore it’s more suitable for companies with regular peak schedules and who follow market trends. Consider it as a first step in the adoption of the Cloud Migration process.


The Shift to SaaS


This method involves outsourcing one or more preferred applications to a specialized cloud service provider. Through this model, businesses can off-load less business-critical processes and be more focused on their core applications. This setup will lead to them becoming more streamlined and competitive.

While this method provides the ability to personalize your application, it sometimes can cause problems in the support model provided by the SaaS (Software-as-a-service) platform. It’s risky enough that you could lose some competitive edge in your industry. This method is more suitable for non-customer facing applications and routine functionalities such as email and payroll.


Legacy Application Refactoring


Cloud migration processes allow companies to replicate their legacy applications completely into the cloud platform by refactoring them. In this way, you can allow legacy applications to function and concurrently build new applications to replace the old ones on the cloud.

Refactoring lets you prioritize business processes by moving less critical ones to the cloud, first. This method is cost-effective, improves response time, and helps in prioritizing updates for better interactions.


Re-platforming


Re-platforming is a cloud migration process that involves replacing the application code to make it cloud-native. This process is the most resource-intensive type of migration of all, as it requires a lot of planning.

Completely rewriting business processes can also be quite costly. Nonetheless, this is the migration method that allows for total flexibility and brings you all the benefits of the cloud to its fullest extent.
