Beyblade, the beginning!!!When you challenge yourself to light up a new data center built in 2 months, things look crazy. As per the comment of my program manager Masthan, “that sounds like spinning our DC-1 Data Center (DC) like a Beyblade, the toy my kids often play at home.” In action, this s...
As we discussed in part 2 of this blog series, a robust metrics service is critical to achieve convergence of metrics and monitoring. Considering the requirements discussed, we were clear that the service had to reside in our data centers for reasons of cost and control. Once we arrived at the archi...
[This is the first post in a blog series on our production infrastructure for metrics collection and monitoring. In this post, we discuss why metrics are critical to our engineering function, and the need for a robust infrastructure supporting metrics collection and monitoring.]Terminology & Taxonom...
A Graphical User Interface (GUI) is a fundamental component in the software we engineer today. It provides an interactive and easy connect to the underlying program making the overall software more usable, e2e workflows more passable and flexible. However, at the quality layer, GUIs pose a number of...
At InMobi, we see events arriving in excess of 10 billion per day. Analysis, reporting and inferencing from these requests (and responses served) is key to serving the right ad, to the right person, at the right time. We have nearly 200 complex big data pipelines that run against various data source...
Several technology companies run their analytics pipeline jobs on hadoop. Though easy to start, managing a scalable pipeline presents multiple challenges across different dimensions. In this article, we focus on one set of those important challenges -- the one arising from the functional testing per...

In my last article I spoke about “Spotting the Right Mentor” as a core responsibility of a mentee. While this is very important to kick start the mentor-mentee relationship on the right note, there is a lot more that a mentee has to do to be efficient and make the engagement mutually enriching. ...
This is the first in a series of blogs that will detail the real-time stream processing at InMobi.IntroductionMany InMobi applications increasingly need to be able to process real-time data in a streaming fashion. The absence of a true streaming alternative has forced many of them to model themselve...
After having been really intrigued by the title of the song Happiness is a Warm Gun, I researched it a bit. The story goes that when he was shown the cover of a gun magazine that read ‘Happiness is a Warm Gun’, Lennon thought it was a fantastic, insane thing to say.“A warm gun means you just s...
At InMobi, we process terabytes of data to produce understandable reports. These reports are queried for and analysed by our customers. Most of our raw data contains a lot of business keys that need to be joined with another set of data, generally referred to as dimension data, to produce enhanced...
InMobi’s engineering principles center around driving innovation for automating and simplifying mundane work. But to uncomplicate engineering routines, one needs to address the unanticipated challenges that arise during the process. As a first of many to come, with this article we deep dive into ...
