What is Data Defined Storage?
Data defined storage is an approach to focus on metadata of the content. It makes the content easily identifiable, manageable and well organized. Data-defined storage is the plan for a new type of modular architectures which unlock the value of data as a business asset. At the same time, it enables the customers to enhance understanding of that data and heighten their awareness of compliance and … [Read more...]
What is the Difference Between SOA and Microservices?
SOA and Microservices are difficult to compare in a fool-proof way. SOA and microservices can be the same, when all the services a SOA consists of are microservices. A service in microservices may be fine-grained with a single responsibility. While service in SOA may have multiple responsibilities. SOA is often towards the enterprise these days, using heavy-weight technologies and protocols … [Read more...]
What to Know to Buy a NFC USB Dongle For Android, PC, Mac
Near-field communication (NFC) is a set of protocols which enables two devices to establish communication by bringing them closer to each other. Most commonly known NFC devices are used in contactless payment systems on credit and debit cards (sometimes referred to as contactless cards). Apart from that usage, NFC can be used for sharing contacts, photos, videos or files exactly like Bluetooth but … [Read more...]
Communication Standards for Wearable Computing
The stationary use of information and communication technology is becoming less important. Nowadays, it is important that information be available at any time, any place, whether in a professional or private environment. Computers are becoming smaller and more compact, and since the invention of digital watches, the idea of wearing a mobile computer on the wrist is playing an increasingly … [Read more...]
What is a Virtual Private Network (VPN)?
This is a recap from our previously published articles to briefly describe Virtual Private Network (VPN) in easy langugage. Nowadays, VPN services for Windows are extremely popular. Many inexperienced users understand VPN as a magic key for accessing blocked web resources: they clicked the button, and the site opened. Yes, unblocking websites is one of the VPN functions, but not the most important … [Read more...]
Tips For Building Digital Switch With ESP32 Arduino
There are some design considerations to increase safety while building an ESP32 Arduino based physical switch controlled by IoT project. In our earlier guide (Controlling AC Powered Appliances With ESP32 and IBM Watson IoT), we have shown the basic of how to use a pushbutton and IoT control together. The case will be using both the pushbutton and IoT control independent. Our that guide is a … [Read more...]

Which is the Perfect PaaS Platform?
We already know that IaaS (Infrastructure as a Service) is a service model of cloud computing where the user outsources the resources used to support operations. Resources including storage, hardware, servers and networking parts. Cost is typically on a per-user basis. Unlike colocation services, in IaaS the service provider owns the equipment and responsible for running and maintaining it. The … [Read more...]
Is it Better to Store Data on the Cloud or on a Hard Drive?
With so much of work and personal lives revolving around computers, just about everyone has a surplus of data, and they all need somewhere to store it. But what’s the best option? There are few methods of storing digital data - either locally on the hard drive, optical drive, memory cards, tape drive or remotely with a third-party service. Both of the options have distinct advantages and … [Read more...]
Required Circuit For Bare Minimum ESP32 Module
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...]
