What Is Edge Computing?
Edge computing is a distributed computing concept that integrates intelligence to edge devices, also called edge nodes, allowing data to be processed and analyzed in real time near the data accumulation source. In edge computing, data does not need to be uploaded directly to the cloud or to a centralized data processing system.

Difference between object storage, file storage and block storage
There are mainly three types of data storage, which are object storage, file storage and block storage. What are they and what are their differences?
-
What Is CDN?
CDN stands for Content Delivery Network. As the name suggests it is a network of distributed nodes (also known as Edge Location Servers) which helps deliver contents (webpages, video, image etc.) to the end-user based on the user’s location, content origin server and the Edge server location.
-
What Is Cloud Computing?
Cloud computing is the delivery of on-demand computing resources (including servers, databases, storage, platforms, infrastructure, applications, etc.) over the Internet. Cloud computing can be used on a pay-as-you-go basis, which means you pay just for what you need.

-
What Is Serverless Computing?
Serverless computing has been dominating the headlines, tech shows, and industry conferences. Even though the idea of ‘serverless’ has been around since 2006, it is a relatively new concept. A lot of people seem to believe that serverless is the natural evolution of computing model.
-
What Is Blockchain?
Most of us have come across all the buzz surrounding Bitcoin! Some of the predictions claim that fiat currencies and gold may be replaced altogether in order to store value or pay for transactions and that the value of the bitcoin may reach to astronomical heights due to its limited supply!
-
What Is VPN?
VPN is an abbreviation for Virtual Private Network. As the name suggests it is a virtual network created over the internet/public network between two or more physical networks (or devices) to create an extended private network.
-
What is the difference among Public Cloud, Private Cloud and Hybrid Cloud?
Public cloud is a cloud infrastructure provisioned for use by the general public, individuals or businesses. Essentially, third-party public cloud providers lease servers within a virtual environment, which is accessible over Internet.
-
What Are the Application Areas of Cloud Computing?
Cloud computing, big data, and artificial intelligence are the three most popular technology fields. In recent years, the Chinese government has attached great importance to the development of the cloud computing industry.
-
What Are the Differences Between Containers and VMs?
Virtual machines are multiple guest operating systems based on hardware, which are emulated by a hypervisor. Containers are an application level construct, and emulate multiple virtual environments which share a single kernel.
-
Five Application Scenarios of Blockchain Technology
The integrated application of blockchain technology plays an important role in new technological innovations and industrial changes. In the fourth industrial revolution with information technology as the main feature, how to take the lead and how to help the industry change in the process of blockchain digitization?
-
What Is Hybrid Cloud?
Before talking about hybrid cloud, let’s quickly recap on what public cloud and private cloud are. Public cloud is a shared infrastructure that allows you to scale up and scale down computing power as needed to reduce costs; private cloud is an isolated infrastructure behind an organization’s firewall, which gives you more control over physical resources but at a higher cost.
-
What is PaaS?
Platform as a service (PaaS) is a form of cloud computing that provides a platform allowing consumers to develop and deploy applications and services over Wide Area Network (WAN) or the Internet. The consumer does not manage or maintain the underlying platform software, middleware and cloud infrastructure.

What Is SaaS?
Software as a Service (SaaS) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted on cloud. Consumers do not need to manage the software architecture, software maintenance and the underlying infrastructure. End users access the SaaS application using a thin client like web browser.
-
What Is Private Cloud?
Different from public cloud, a private cloud is a model of cloud computing that provides a dedicated cloud environment to a single organization. Private cloud can be operated internally by an in-house IT team, behind that organization’s firewall, so an organization has more control of its compute resources.
-
What Is IaaS?
Infrastructure as a service (IaaS) is a form of cloud computing based on automation and orchestration technologies to on-demand provision and manage virtualized infrastructure resources such as server, storage and network over a wide area network (WAN) to the consumer.
-
What Is Virtualization?
In cloud computing, virtualization refers to hardware virtualization, which means to create virtual machines within an operating system (OS).
-
What Is Object Storage?
Object storage, also known as object-based storage, is a type of data storage in which each unit of data is stored as a discrete unit called an object. An object can be a discrete unit, anything like a pdf, audio, image or video file.
-
What Is Hypervisor?
A hypervisor is a software layer installed on the physical hardware, which allows splitting the physical machine into many virtual machines. This allows multiple operating systems to be run simultaneously on the same physical hardware.
-
What Is Containerization?
Containerization is a type of virtualization at the application level, which allows for multiple isolated user space instances on a single kernel. These instances are called containers.
