Value of cloud migration
Have you recognized your reason for migration to cloud in the list above? Let’s now talk about the potential value you can get when migrating to the cloud.
Here are 5 most valuable benefits:
With access to the cloud, business owners improve collaboration within their companies. The same goes for collaboration between employees and customers. You as a sales representative, for example, can instantly reply to a customer with the required information attached right off any device.
The manager won’t need to get to the office to answer the request. The customer, in turn, would be glad to receive the reply as soon as possible. That works well especially for businesses where quick replies to customer requests are must-have — insurance, banking, fintech, healthcare, to name a few.
“Pay for what you use” is the main pricing principle of cloud services. Typically, cloud service plans include the price of the web server hardware, support, maintenance, etc. In such a way, you can decrease operational costs significantly. To make sure that it’s true, you first will need to analyze and calculate the total cost of ownership (TCO) for cloud computing technology if adopted by your business.
Cloud migration can give a rise to integration capabilities, which, in its turn, will ensure real-time data exchange. By getting real-time data, you can improve decision-making and forecasting in your business.
Fast-growing SMBs and enterprises find it a true pain when they can’t scale up with the desired pace. This is a real challenge when it comes to a growing number of customers, products and services, data that should be stored and analyzed according to certain regulations. Cloud allows for painless scale-up or scale-down with your existing IT infrastructure.
Most cloud service providers comply with security regulations introduced in PCI-DSS, HIPAA, ISO27001, AICPA/SOC certificates. Besides, they provide much more security features than traditional data centers. So, you can rest assured that your business data is safe.

What are the cloud migration types?
Three types of cloud migration include: full, partial, parallel. Let’s have a look at what each of these means.
- The full migration is referred to the on-premise to cloud migration type. Traditionally, it’s the process of moving existing physical IT infrastructure (applications, data, setting) to the cloud. The end result of this migration is the same infrastructure that is known and clear to your employees, but in the cloud. Small and middle-sized companies usually choose full migration as their IT systems are not as large as those that belong to enterprises. The execution typically takes a few days and faces minimal risks. The disadvantage of this type is that not all cloud capabilities are available.
- Patrial migration is transferring just a part of the IT systems and data to the cloud. That is a good way to test the cloud service and understand if you really want to move your infrastructure fully. Usually, large companies use this approach.
- Parallel migration means that you can use your existing system while migrating to the cloud. The peculiarity of this migration way is that you will need to maintain both systems simultaneously.
