Despite having world class reliability systems, some incidents do occur making varying levels of impact to our business. One of the many steps involved in the aftermath of the incident is measuring its impact.
Accurate measurement of financial impact due to an incident is an important part of incident management and is needed in real-time for many reasons including regulatory requirements.
However, it's not easy to calculate the impact given the dynamics of the complex distributed system. As SRE is deep-rooted in automation, we have built an Incident Impact Calculation Framework that accurately measures the incident impact using various Statistical and ML Models. It runs in seconds, is completely automated and fits well with our other incident management tools.
Building a real-time, reliable, and robust impact assessment framework is not as straightforward as it seems. Join us in this session to know more about impact assessment, its design, and challenges.
