This is my personal view and understanding of ODA, can anyone please clarify or confirm if this is correct.
Currently, CSP enterprises are divided into walled garden boundaries such as BSS, OSS and Networks. ODA FF allows CSPs to transform and migrate to functional blocks so that Verticalized Enterprise can be created per business/product line. For eg. Fixed Line Broadband services, Voice Services, Data Services, Information Services, Media/TV Services, Mobile Services, etc. where the CSPs can create "ODA in a Box
" for each of those service/product lines so that independent evolution and Agile delivery can be done easily. Earlier, Networks used to be the major barrier but now due to virtualization and containerization in Networks makes it quite possible to create verticalized Enterprise blocks (end-to-end) per product/service.
While having that distributed ODAs per product/service line, enterprise level monetization & business alignment can be achieved using the Mesh and Orchestrated Integration Architectures & Platforms and also by having the unified plane for security, regulation, policies, reusability, sustainability , etc. This will allow CSPs to replicate the "ODA in a Box
" to get the benefit of reusability, agility, dynamic and ondemand platforms so that new products/services can be introduced to the market quickly and easily especially when the CSPs are transforming into Digital Enterprises for Cross-Industry play beyond he connectivity.
I like this ODA concept where it is giving an open standard and framework for the enterprises to adopt. The functions can be implemented onprem or cloud or edge. You can have an enterprise where a certain new product/service line (eg. 5G related) has ODA implemented as a green field while the existing implementation will continue until the transformation is planned. A major advantage with it is that enterprises can pick and chose certain functions to start the transformation from the existing implementation for less risky and less complicated migrations in phases with specific outcomes.#OpenDigitalArchitecture
