The Cloud is a great solution for startups that have no legacy infrastructure, for them it is as simple as subscribing to number of necessary cloud services, writing an app, provisioning some cloud space and their business
Up to 70% of current enterprise applications would benefit from moving to the cloud. This of course differs from company to company, depending on the age of the business, the architecture of currently used applications and technical demands of industry it operates within.
Before any type of cloud migration it is imperative that enterprise applications are identified and categorized, this will enable analysis of costs and efforts needed to move them to the cloud. Before moving critical operations to the cloud, companies should try with less significant applications and from there build a business case for other good candidates.
1. Compatibility
The process of migrating application to the cloud will be far smoother if the cloud service provider can offer the same operating systems and middleware environments that the company is already using. This compatibility ensures that those applications can be moved to the cloud without significant rewrites, thus saving time, money and frustration.
2. Security
The security is one of the main aspects of anything related to IT and when moving any application from relative safety or on premise environment to a third-party provider, security must be considered. The level of security that will be applied to a cloud based application in essence depends on the sensitivity of the data. Security measures such as access controls, authentication and encryption are a necessity for applications that deal with highly sensitive information. Keep in mind that regardless of the “location” of the application compliancy requirements still stand.
3. Migrate gradually
There is no doubt that cloud has appeal but moving majority of applications to the cloud may bring more regrets than benefits. A gradual approach, migrating one at a time may be slower but much more beneficial in the long run. Ideally the initial application moved to the cloud would be the non-critical one, that doesn’t deal with highly sensitive data.
4. Not everything is for cloud
Although migrating applications to the cloud can offer many benefits, it’s not necessarily the right choice for every business application. Moving a complex legacy application might end up taking more work and investment than it is worth. But when considering new applications cloud should be considered. Weigh the pros and cons of the cloud against developing or deploying application in-house.
5. Responsibilities remain in the cloud
Among many benefits of the cloud, one is the managing and maintaining of the application which is handed to the cloud service provider, however this does not mean that the company is without responsibility. This is particularly important if the company is considering a hybrid approach where an application that you are running in the cloud communicates with the ones you are running in-house. Company requires a manager to stay on top of integration....
