Controlling AC Powered Appliances With ESP32 and IBM Watson IoT

It is an upgrade to our previous article to control ESP32 Arduino LED from IBM Watson IoT. We already talked about Android Apps for Watson IoT for this purpose. We already have an article to use relay with Arduino. Our linked relay guide should be enough for anyone to understand how to use relay and AC connections. These relay modules will create mechanical clicking sound like switch. My relay … [Read more...]

Static Website with Jekyll, Object Storage and OpenWhisk Serverless

This article is mostly for providing the idea of how in the last 10 years we are progressing to host small websites on free to cheaper cloud storage. Many readers are Most of the peoples with some work over the internet are used with Jekyll and OctoPress. They are static site generator and also management tool. So far, we could host our static websites on various platforms including Object … [Read more...]

Does Serverless Computing Offer the Benefits of Microservices?

Often this kind of question arises in the mind of who are new to the world of cloud computing. We have discussed some basic around serverless including What Problems are Solved by Serverless, Relationship Between Serverless Computing and Microservices, What Is a Serverless Microservice and so on. Serverless is an excellent environment to build a microservices architecture due to optimal … [Read more...]

Control ESP32 Arduino LED from IBM Watson IoT

Anthony Elder published a guide on developerWorks Recipes on how to "Build your own Watson controlled kettle" for ESP8266. This article's code is shamelessly ripped-off from him for broader usage. This guide will show how to turn on and turn off a LED connected with ESP32 Arduino from IBM Watson IoT platform. That "remote control" over the internet will be shown by using a simple bash scripts - … [Read more...]

An air … [Read more...]

Fix : Hard Disk Full of MySQL Log Files, MySQL Failing to Start

Server hard disk full is quite common matter, especially on the cloud servers. Usual disk space allocated on common RAM size cloud server instance is 30-40GB. Bigger websites easily eat up 10GB space for the media files. System files including running applications take more than 10GB. And for WordPress, full hard disk will result showing up the infamous "Error Establishing a Database Connection" … [Read more...]

How Are Serverless Computing Platforms Different From PaaS?

How Are Serverless Computing Platforms Different From PaaS? Both backend architectures keep the backend management to zero is one big resemblance. With PaaS, we paying for the whole and but in Serverless Computing, we pay only function execution. Origin of Serverless is plain HTML webpages. PaaS and Serverless share lot of similarities in terms of operational abstraction and productivity. … [Read more...]
