What the business case is really about
Lower vendor lock-in risk. Solid’s central idea is that data is kept separate from any one app, so a business is less exposed if an app is replaced or a vendor changes terms.
Lower change cost over time. If apps consume data through a common model rather than owning it, you can change one application without rewriting every dependent integration. That is the core business case Inrupt makes for Solid.
Better portability and continuity. Data remains useful across systems, which helps with mergers, app replacement, and internal platform changes.
Potentially simpler architecture for some use cases. Microservices and micro-server approaches can improve agility and scaling, but the evidence is mixed and workload-dependent rather than universally superior.
