How did Red Bus, India's largest bus ticketing company, thrust its way to become 15 times larger than its nearest competitor?

What gave the RedBus CTO the peace of mind as he boarded financial apps on the cloud amid data security concerns?

To date, RedBus has already sold two million plus bus tickets, and has more than 100 bus operators using the software to manage their operations. At present, RedBus has 700 inter-city bus operators, out of the total 1,200 inter-city bus operators in India. 

The story opened on a day in October 2005, when online bus ticketing was still non-existent. One of the RedBus founders failed to get a bus ticket to return home for Diwali -- the most important Hindu festival for family get-together.

While the rest is history, the RedBus founder decided to build a common bus ticketing platform which would build on "a common server where all bus operators could offer tickets on a first-come-first-served basis," so bus tickets would be as easily purchasable as air or train tickets.

After using one of the traditional data centers for over a year, however, RedBus quickly ran into the problem of scaling. "The procurement of new servers, upgrading existing servers and most of the developer's time went into circumventing scaling issues which were not adding values to our core business. That's when we decided to try out the cloud," said Charan Padmaraju, co-founder and CTO, who currently heads an IT team of 20.

"We wanted the developers to focus on developing and enhancing the application that would improve our offerings to customers and not spend unproductive time on IT infrastructure," Padmaraju added, "having run pilot tests and proof of concept, we learned and gained experience on how to operate in the cloud which helped us to build our cloud strategy in 2008."

In the early phase of RedBus operation, the company had fixed number of servers with limited capability which failed to scale at all.

"We also didn't have much option in choosing computing resources, configuration and the types of operating systems we want. Moreover, procuring a new server or upgrading an existing server took more than two weeks! For examples, once we wanted to open a port on one of our servers and it took two days," said Padmaraju.

"On another occasion, the memory size wasn't enough to service the workload, the process to upgrade took more than a month and our business took a hit -- this is when we decided that we had enough of this infrastructure constraint and moved our entire infrastructure to AWS [Amazon Web Services]," he added.

Before AWS, RedBus was unable to service its customers in a quick turnaround time frame. "After moving to AWS, our traffic has increased more than 50%! We are now able to launch multiple products for bus operators on SaaS model. This is possible only in a cloud platform due to its elasticity and scalability." According to Padmaraju, RedBus have also been able to fully tap its analytics requirement with AWS."
