When you need many ESP32 for projects then you'll save money by avoiding full development board. Import tax is quite higher in many countries, yet the bare ESP32 module cost only $3. Bare minimum ESP32 module is more than System on Chip. ESP32 module, unfortunately, does not have built-in USB–TTL/ UART hardware. That costs $1.5 per piece and you do not need to connect USB–TTL/ UART hardware … [Read more...]

What is Interoperability in Cloud Computing?
Interoperability in cloud computing is a state where the cloud services can understand each other's APIs, configuration, authorization. Interoperability means enabling the cloud ecosystem so that multiple cloud platforms can exchange information. Interoperability in cloud computing gives the ability to the customers to use the same or similar management tools, re-use server images and other … [Read more...]
Develop WEB Applications with ESP32 and IBM Watson IoT
Here is How to Develop Web Applications with ESP32 and IBM Watson IoT. Often, using an HTML page with JavaScript is practical than developing an Android App. Because, web applications can be hosted on own cloud server or cloud storage service - thus it becomes device independent. Securing access to such web application usually, need minimal configuration for the Apache2 server. Cloud storages … [Read more...]
Is Serverless Architecture is the Future?
Despite Serverless has problems and challenges at present, in many use cases, Serverless actually used at the backend. Lack of standards, tooling and vendor lock-in are problems and risks for those who are not the cloud service providers. Rather the mass consumers. However, the cloud service providers of IBM, Microsoft, HP sized use serverless for delivering their services. We simply do not know … [Read more...]
