Since its inception, the cloud has played a critical role in enhancing IT infrastructure and driving company growth. By moving to the cloud, businesses may become more responsive, improve operational efficiency, save administrative expenses, and enhance the customer experience.
Strategies for Cloud Migration
Public, private, and conventional on-premises cloud computing systems are all common in today’s IT infrastructures. In the IDG Cloud Computing Survey, 73 percent of top IT executives stated they had already embraced this mix of cloud technologies, with another 17 percent planned to do so shortly.
Businesses are putting money into the cloud, according to recent studies. So, according to the IDC data, in 2019 cloud migration consulting climbed by 26.9 percent.
All companies spent 84.6% of their budgets on public clouds, compared to 15.4% on private clouds. The retail and wholesale commerce, financial services, and manufacturing industries all used the most cloud services.
There are firms that utilize the IaaS cloud model to increase the capabilities of their current hardware and storage systems, while others use the cloud as an extra platform for non-critical services or as a development environment for their IT infrastructure to be moved to the public cloud.
Migration to the provider’s cloud helps to take the first step towards the digital transformation of the company, open up options for the execution of new IT projects that were before impracticable.
What is cloud migration?
The act of moving digital corporate processes to the cloud is referred to as cloud migration. It entails shifting data, applications, software, PCs or infrastructure to a provider’s cloud environment. There are two forms of migration:
- on-premises infrastructure to cloud platform;
- the shifting between various cloud platforms (from another provider).
This method needs quite a lot of planning, but is generally worth the effort, resulting in cost savings and better flexibility.
Techniques for moving to the cloud
Cloud application migration may be accomplished in a variety of ways, including moving existing apps “as is” or starting from scratch with a new one.
It’s possible to use a method called “lift-and-shift,” in which an organization moves its own native apps to the cloud rather than keeping them on the ground. A lift-and-shift may involve moving application executable files to a new location.
It may also involve making new virtual machine images, setting up security groups, setting up Elastic IPs, and setting up DNS and moving a database to another cloud database.
Refactoring. Assumes that the application has been made to work better in the cloud. In an organized manner, a component of an application’s code may be reused and recorded.
A new cloud-based application has been developed as a result of revising the original. This strategy is very essential for transferring older programs.
Despite the extensive upfront planning, refactoring is the most lucrative strategy in terms of long-term business outcomes and is more likely to deliver a return on investment in the long run.
Lift-and-shift and refactoring are both lower-level migration approaches; re-platforming is a middle-level strategy. Using dynamic scaling or creating a managed database are just two examples of how the system design might be improved.
Lift-and-shift may be faster, but the company will miss out on the advantages of cloud infrastructure if they choose this migration technique.
For example, implementing autoscaling for internal workloads might minimize the pressure on DevOps to manually add and scale down instances.
