What is this ‘fanout’? Fanout is a common design pattern used in cloud applications, to take advantage of parallel processing. Parallel processing — example Let us see how OTT providers like Youtube, Netflix, and Amazon Prime use this pattern to save time in solving their important time-consuming tasks of video transcoding, optimized for different devices […]

TL;DR: Serverless removes the architecture responsibilities like hardware provisioning, scaling, and maintenance in cloud-based application development. Serverless Architecture Serverless (also called Serverless computing) is a way of software development, where the software application is built and run without having to manage servers (hardware). This is more attractive for application developers as it provides a complete abstraction […]

What is Virtualization? Virtualization is the means by which we create a virtual counterpart of an actual item, by software or hardware & software. The virtualized item could be another hardware, operating system (OS), storage device or network. As defined above we have,Hardware virtualization for virtualizing any hardware device.

Industry standard DRMs (like Widevine, Playready, Fairplay) protects content in all possible ways. Transferred over the internet (content is always encrypted, licensing key exchange is through HTTPS key exchange mechanism) Played back on devices (hardware level protection) In this blog we will see how the content is encrypted and encryption key are transferred and used […]

Compiling driver: As discussed earlier a Linux loadable kernel module (LKM) is different from other binary executables. Hence, it cannot be compiled the way we compile normal C files. Compiling a Linux module is a separate process. We use the help of kernel Makefile for compilation. The makefile we will have contents as given below. When you […]
