In recent years Cloud Computing has gained an enormous amount of popularity in the IT sector. In order to adapt to the new normal to thrive, and to continue to remain functional, organizations are deploying migration of applications from on-premises to cloud servers. From being easy in deploying, rapid scalability, and cost-effectiveness, there are many reasons why companies are migrating from on-premises to cloud servers.

There is no denying that cloud services provide the utmost level of security and an ample amount of space for storing data, along with easy access to everyone no matter where they are accessing. While migration of applications from on-premises to cloud servers is trending mostly in the IT sector, have you ever wondered what the pros and cons of migrating to cloud servers are?

“The connectivity of the cloud and the prevalence of tablets and smartphones have eroded the traditional online/offline divide. Within a short time we will most probably stop thinking of it as “online.” We will simply be connected, all the time, everywhere, and the online world will be notable only by its absence when that connection breaks.” – David Amerland, author and digital strategist

This article will give you an overview of what are the pros and cons of migration of applications from on-premises to cloud.

Pros of Cloud Migration

Migrating to the cloud can solve many problems an organization faces. Let’s take a look at a few such scenarios.

  • If an application is experiencing upsurge traffic, and it’s downgrading the scalability of the resources on the organization’s on-premise server, migrating to the cloud server will solve this problem in a jiffy, as it has rapid scalability ability. 
  • Clients of a certain organization want to expand their geographical territory, and as per the organization, setting up a multi-region on-premise infrastructure along with maintenance, and human resources could be a challenge to meet in a short period. While moving to cloud services can solve this challenge, as it can be accessed by anyone from anywhere in the world.
  • Meeting the growing need for storage is expensive for on-premises data storage servers. Cloud servers not only cater to the growing need for storage but also it is less expensive compared to the on-premise storage infrastructure.

Cons of Cloud Migration

As we know, everything comes with some negative attributes along with the positive qualities, and this makes one of a kind. The same goes for Cloud technologies and services. Take a look at these few risks that migration to a cloud server possesses.

  • If an application stores and retrieves very crucial data, it would become difficult to maintain it in the cloud. As a result, a company will have restricted options to choose from because of the compliance requirements.
  • If any technology used by an organization is marketed under and protected by a registered trade name, the organization cannot deploy it legally on the cloud.
  • Every application has its particular design and architecture that might not be compatible with distributed cloud architectures. Thus, it might need modification before moving to the cloud, which will require resources and extra time.
  • Vendor lock-in or cloud platform lock-in is one of the concerns that many organizations have faced and reported. In this, once a company is locked in with any one vendor or cloud platform, it’s difficult for them to switch to another cloud platform or use multiple cloud platforms at the same time.

All that has been said, even with a few setbacks, cloud technology is the bright future the world is moving towards. The Cloud Computing domain holds an enormous amount of opportunities for every cloud technology enthusiast, one just needs to upskill themselves to grab these opportunities.
