What Are the Drawbacks of Serverless Computing?

Serverless computing or FaaS provides a platform which allows the developers to execute code upon call of events. The serverless platform separates infrastructure services from the applications running on top of the platform. Automatic scaling functionality of FaaS not reduces the compute cost but and operational management overheads. In the serverless solution, we pay for the managed servers, … [Read more...]

How Are Big Data and Machine Learning Related?

Machine learning (ML) in short algorithms which can learn from data without relying on rules-based programming. Big data is the type of data that may be supplied into the analytical system so that a Machine learning (ML) model could learn to improve the accuracy of its predictions. Big Data and Machine Learning have a weak relation. We can only apply Machine Learning on Big Data or Big Data can … [Read more...]

Two Way Communication in IoT (Cloud to Device and Device to Cloud)

Commonly, we send data from the devices like ESP32 Arduino, Smartphone, Raspberry Pi, Smart Watch to the IoT platform. IoT platform can be self hosted or on the cloud. Example of actual such one way communication can be our example simple project, such as ESP32 Arduino sending temperature, humidity data to IBM Watson IoT platform. We already know the theory around machine to machine communication, … [Read more...]
