Architectural practices for greater scalability and innovation

Architectural practices for greater scalability and innovation

When dealing with application scalability, it is common to deal with topics such as microservices, cache, and NoSQL, among other buzzwords in the software engineering area.
However, particular needs are often overlooked, such as: ensuring that the organization's point of failure is not IT. But instead the human factor.

One of the biggest challenges in software engineering today is ensuring that the technology park grows and innovates while being stable and resilient. Delivering innovation with stability, despite sounding utopian, is possible through well-orchestrated work.

This talk will teach practices that lead to a well-documented, multiplier architecture.
