A micro-story of achieving business and technical results before microservice era @ Ydilo.

Ydilo provides Voice Recognition Application managed services for large enterprises: Vodafone, ING bank, Spanish Traffic Gov system, Movistar...

I worked from day 0 at Ydilo as core member team along with co-founders at this Startup as Operation and System Director. Then I joined back them later in 2006+ as part time CTO. At that time, Ydilo was already recognized worldwide as the best successful voice recognition hosted provider in Europe: largest voice call traffic and fully automated calls percentage (invited to present at NY VOX conference 2006, where we introduced Mobile 'future' customer care apps.). Granted pattents 

Given the state of the art in the 2000/10's decade, there were lot of technical challenges we resolved at all levels (architecture, operations, development, system hosting...) to provide a 100% software based 24x7 telco-grade service. To put this in context, Ydilo were competing with telco hardware level solutions.

Microservices & Cloud didn't exist at the time, but with a good architecture and implementation in place a lot of the same patterns were applied already: breaking components in small and independent small silos, multi-tenant/multi-version support of applications and content, in-house content (voice) production pipelines, micro-(voice)-apps dynamically added to multi-tenant (voice) portals, individual customer SLAs under same platform, on-demanand scalable architecture...

So, what would be in my opinion the main difference (from tech viewpoint) between this experience and a potential similar project developed nowadays? I would say: COST.
