Introduction to Cloud Migration
The following article provides an outline for Cloud Migration Challenges. The process of transferring data and applications or different business elements onto a cloud computing environment is called cloud migration. There are many types of migrations onto a cloud environment an enterprise can do. One of the most common way to do it, is to move the enterprise’s data and applications form a local data center to a public cloud. However, one more type of cloud migration is done where the data and applications are transferred from one cloud to another cloud provider, this is called cloud to cloud migration.
Moreover, there is one more type of cloud migration which is called a cloud reverse migration or cloud exit or cloud repatriation in which the data and applications are moved out from a cloud and transferred onto a local data center. However, there are several challenges associated with cloud migration.
Various Cloud Migration Challenges
Successfully transferring data onto a cloud needs complete attention from the enterprise. If in case, the business is not fully prepared to cope up with the challenges associated with cloud migration then there could be problems arising after some time which may induce loss of money and data for the business. However, understanding these challenges and considering the trade off between the pros and cons of cloud migration would help the business in making their important decision. Moreover, understanding the challenges before starting to migrate the data onto a cloud would be very beneficial or the business in a long run.
Here, the major challenges associated with cloud migration is listed in detail and also the ways to overcome them are given.
1. Making a Strategy for Cloud Migration
Information technology professionals understand that any new technology can’t be just adopted without a concrete strategy. A strategy helps the business in understanding the pros and cons of a technology and how to deal with it in case of errors and miss happenings. Cloud computing is also not untouched with this perception. Making a strategy before migrating onto cloud is one of the most important part of cloud migration. This not only means, making strategy for choosing the best suited cloud provider for the organisation.
Moreover, the business needs to understand the cost associated with the process, the downtime of the project, training of the employees and the total time taken for the migration of data and applications. The last factor is one of the most important as migrating all of the data and applications can take a large amount of time which totally depends upon the size of business and the amount of data which is being transferred onto the cloud. Sometimes, cloud migration also takes months to get completed.
2. Dividing the Complete Process into Small Stages
The worst strategy a business can make while migrating the data and applications onto cloud is to transfer everything onto the cloud platform at once. As most of the businesses now a days are very much eager to migrate all of their data onto cloud but take the worst step by not strategizing which data should be moved first and what could be the flow of migration. As, with this strategy the company can get stuck in between the cloud migration and lead to a complete disaster.
The best way to do it, is to start migrating the redundant and non-essential data at the very first step as it would help in understanding the process of cloud migration without the risk of losing essential data. As there is a chance that the people who are completing the task of cloud migration may make an error which would lead to the loss of data, corrupted files or even not securing the data onto the cloud. Any business should not take this type of a risk with their sensitive and important data which is very much critical for their business, especially in the situation where the business needs to maintain their compliance.
3. Cost Analysis of Cloud Migration
Migrating data and applications onto a cloud platform can be very much costly, it can be of a higher degree if the business has not projected the total cost of data migration before hand. However, migration of data onto a cloud platform is very cost effective in a long term but the initial cost could be very high which entirely depends upon the size of business and amount of data to be migrated.
Only the cost of data migration should not be forecasted but the cost which would occur for training the employees about the new technology their employer is introducing should also be considered. Moreover, the cost associated with rewriting the data or even replacing the data for making the data which would be transferred onto the cloud, compatible with the architecture of the cloud.
4. Cloud Security
Security is the most important factor, a business should consider while migrating their data onto a cloud platform. This can save the business from long term losses. Considering security as the topmost priority is always the smartest approach for the business, especially in the times of adopting a new technology. Migrating the data onto a third party cloud platform means that the business trust a third party organisation with their sensitive data.
If the cloud platform is trustworthy and has demonstrated their trustworthiness in the market then nothing can the stop the business from flourishing, if in case the cloud platform cannot be trusted then the business can incur huge amount of losses. Moreover, the business should fully understand the security practices of the cloud provider. The business should have the knowledge about the location of data storage and how the cloud provider is encrypting the moving the data in and out and the regulations with which the provider is compliant.
On the basis of the above article, we have seen the major challenges associated with migrating data onto a cloud platform and how to overcome the challenges. The points discussed in the article would help the businesses in choosing the best practice or their cloud migration.
