With the hardware costs becoming cheaper day by day and with industry giants focus, Cloud computing has exploded and reached leaps and bounds in the last 15 years. With the power of creating, using and destroying virtual machines in the cloud at the tip of mouse click, industries have started moving their core applications to the cloud. This has reduced the hassle for industries to maintain the hardware by themselves. Tech giants like Amazon, Microsoft and Google are head of the game and the fierce competition between them has led to astonishing innovation. With so many players in the cloud market, it is essential for cloud users to know how each of the services provided by these cloud service providers are performing against each other. In this paper we have evaluated the performance of famous OLTP benchmark TPC-C on these cloud providers. It is observed that Amazon's AWS has performed better than Microsoft Azure and Google Cloud Platform in terms of the number of transactions/orders per second, and I/O reads/writes. We have done the extended comparison with respect to transaction throughput, database throughput and Machine throughput. 

Transport Network companies (TNCs) have changed the way we travel in the last five years where a rider can book a ride using her smartphone. However, TNC doesn't provide any robust mechanism to validate the driver or the rider before the ride. This has led to many violent incidents ranging from assault, kidnap of the riders by fake ride-hailing drivers. The most recent one that shook the entire nation is the murder of a USC student when the rider got into the wrong car thinking that it is her Uber [1]. To address this problem, we have proposed a solution that adds an extra security layer in authenticating both rider and driver before initiating a ride. In this solution, both rider and driver will authenticate themselves using technologies like QR Code and fingerprint biometrics supported by modern smartphones before they take the ride.
