Which Legacy Apps Should You Move To The Cloud?

move legacy apps to the cloud

A growing number of companies are transitioning to cloud computing, which provides many key advantages. If you are moving apps to the cloud, knowing which legacy apps should and should not be moved is extremely important. Below are some tips that will help you make the most prudent choice.

Consider Federal Regulations

Data transmission and usage may be subject to legal restrictions. For instance, many governments have laws which place restrictions on consumer data being transferred outside the country, which means that they will have to remain in data centers that are localized. Knowing which apps are restricted is extremely important when performing cloud migrations.

What Is The Availability?

How often will you use the app and what latency requirements does it have? Any app which is needed seasonally or sporadically will work well on a cloud that is public, along with those that have transmission requirements which are medium or low. Any system which is life critical, such as those involving healthcare, should not be moved without considering the risk implications.

Flexibility And Performance

How integrated is the application? The cloud is a superior option for standalone applications or those which only perform batch integrations. You also have to consider the transfer rates of the database as any applications which have low transfer rates or CPU requirements are optimal for cloud migration. By contrast, high end applications may be too complex to transfer. Apps which are integrated are viable as long as they are compliant to industry standards.

Security Considerations

Data privacy is a growing concern for many businesses and as such, applications that don’t contain data which is highly sensitive can be used in the public clouds. Applications that do should remain in secure data centers or can be placed in hybrid clouds. No matter which option you choose, always think about the latest security features and performing critical updates regularly.

Storing The Data

Your data should be securely stored and you should also have recovery and backup plans set in place so your business can continue operating and or quickly recover during an emergency. Some apps are, to a large extent, decoupled from data which is processed through them, or they may have considerable requirements for data storage. These apps are excellent candidates for the cloud and can typically be migrated without a great deal of effort.

In Retrospect

Enterprises today must decide where to best focus their time, resources and energy so that they can foment growth and innovation. Updating applications and transferring them to the cloud is a great step in the right direction, as it encourages scalability and cost reduction while maximizing performance. However, there are risks involved with transition, and these risks must be managed. The best way to do this is to look before you make the plunge. Always understand the factors which make an app good for cloud migration, and which app will be better left in the data center.
