High productivity platforms based on 4GL and Visual tools serve the non-technical business users for building simple, long tail applications. They also have disadvantages such as proprietary development environments and platform lock-in.
On the other hand, ground-up development the traditional way, using developers who write code, is not only time consuming but also risky as there is no unified platform, architecture and engineering structure that can be enforced across the organization. The design challenges of Cloud, SaaS and Multi-tenancy, increases this risk multi-fold.
Techcello is a third alternative that gives developers and architects the freedom, flexibility and control of custom development, without the costs and risks associated with ground-up development.
