Refactor
Application refactoring focuses on restructuring the existing code base without changing its external behavior. One of the key benefits for the customer is it greatly improves Non-functional requirements and attributes of the application. In Agile programming, this becomes very useful. We can make the code base simple and clearer to the developer community without impacting the Business user, thereby extending the life of the application and its maintenance. In addition, UI enhancements can be implemented on top of existing core-functionalities.
Replatform
In the age of Cloud computing, one of the immediate benefits of the Cloud offering is to move a part or an entire application to the Cloud.
Upstream and Downstream services are evaluated and if needed, broken into microservices, before changing the application platform from on-premise to the Cloud. Our team evaluates existing applications using modern analysis tools and provides options for Replatform.
Rehost
Lift and shift is a strategy for moving an application or operation from one environment to another – without redesigning the app. In the lift-and-shift approach, applications, workloads, database and tasks can be moved from on-premise Legacy Mainframes to Distributed environment, either in the cloud or on-premise. This approach delivers a quick and easy migration solution as it can be migrated with minimal business disruption. Large enterprises looking for quick migration without disturbing the existing application workflow generally choose the rehost approach. Once they migrate using the rehost approach, it is easy to re-architect and optimize the application as they are already done with the difficult part. Granthium provides specialized expert services for rehosting.
Retain
This approach to modernization primarily focuses on what aspects of an application and its related services need to be retained. As a result, we extract the business logic of the legacy application, redevelop the application, and retain the essential services required by the Business. This helps to weed out the unnecessary hundreds and sometimes million lines of code that would have grown organically over the years. Six Sigma and Lean principles play an important role in this space. This can be time consuming, cost intensive, but, in the long run it benefits the company to cope with changing demands of the industry.
Retire
One of the main observable facts in majority of the organizations is the technical waste incurred by applications and services that should have been retired long time ago but they continue to exist, consuming valuable resources and costing tons of money. Our team evaluates such conditions, breaking down the ecosystem to bring clarity to the business and helping to retire them without major impact to the organization. We provide resources and services to effectively retire the applications and services at the shortest time period.
Even if there is no new replacement at the moment for the retired application, a repository of the process and features is maintained that can help to make the right decision to fill the void in future with a replacement application and services.
Replace
Technology is constantly changing, so too are the needs of an organization. In many instances, it makes a stronger business case to retire and replace the existing application with a better functioning application that meets the current needs. In a distributed environment, this might be comparatively easier, since there are many new applications that are available off-the-shelf, either through specific vendors or through the community – for instance AWS EC2 Market-place AMIs and Community AMIs that can further be customized. In the Legacy world, there is a growing need for such services.
