Excellent Code Quality is Also an Issue

Reading Time: 2 minutes We all know the importance of good clean code. Meaningful names, ubiquitous language, one level of abstraction per function, SRP, OCP etc etc. It is not debatable that good code would lead to better reuse, maintenance, enhancements etc etc. Have you ever encountered the scenario where the code was too good and that was an issue?

If these events are routed through an intelligent system that can find the correlation between the events and then take proactive action Continue Reading

Comparing Event Processing and Rule Engines

Reading Time: 3 minutes Recently, there has been a lot of talk about CEP and the benefits that it can bring to the industry. CEP is the analysis of event data in real-time to generate immediate insight and enable instant response to changing conditions.

The Continue Reading

What Does 99.99% Availability Mean?

Reading Time: 2 minutes Availability is defined by uptime. I.e. the time between failures. It is dependent upon Downtime and Recovery Time Downtime is the amount of time that the system is unavailable due to either failures or scheduled maintenance. Recovery time is the average time it takes to recover from failures. This includes time for detection, isolation and resolution. Hence to have high availability, you must have low Continue Reading
