IoT and Cloud Computing
The Internet of Things (IoT) is a new way
to link sensors, controllers, machines, people and things together in a new way
by using communication technologies such as local area networks or the Internet
for sense, realizing the connection between people, people and things. Things
and things, to build an information-based, remote management and control, and
The three key technologies of the Internet
Sensing technology: Sensing technology is
the key technology of the Internet of Things and the key technology in computer
applications. Since the computer, it needs sensors to convert the analog signal
into a digital signal, and the computer can handle it.
RFID technology: RFID technology is a
fusion of wireless radio frequency technology and embedded technology, a
comprehensive technology in automatic identification. Logistics management has
a wide range of application prospects.
Embedded system technology: Embedded system
technology is a complex technology that integrates computer hardware and
software, sensor technology, integrated circuit technology, and electronic
Cloud is a metaphor for network and
Internet. It is a new type of computing method based on the Internet, with a
computing capacity of 10 trillion times per second. Through this approach,
shared hardware and software resources and information can be provided to
computers and other on-demand devices. The cloud can be divided into several types:
basic platform, management center, application center, and security center.
For smart home, all functions of the cloud
are based on the Internet and mobile Internet. A typical cloud provider will
provide common web-based business applications, logged in through other
software or web services, and stored on the server.
Smart home is a small Internet of things.
It has a huge hardware group, this hardware group collects huge data and
information, the stability and reliability of this information must be built on
the basis of good hardware, which requires a large enough capacity of storage
equipment, if there is no sufficient capacity of storage equipment, it will
cause information difficult to store, or even lead to a large number of
information data loss. Therefore, cloud computing is born, which centralizes
the vast data and realizes the automatic management of the smart home.
Cloud computing is a commercialized super
large-scale distributed computing technology, which means that users can
automatically divide the required huge computing process into countless smaller
sub-processes through the existing network, and then hand it over to a larger
system composed of multiple servers to search, calculate, and analyze, and then
transmit the processing results back to users.
Preliminary formation: Google Cloud has
more than 1 million servers. Amazon, Microsoft, IBM, Yahoo, etc., all have
hundreds of thousands of servers, so it can be seen that the “cloud”
has taken preliminary shape.
Non-physical: The “cloud” is not
a fixed, tangible entity, so users do not need to know or worry about the exact
location of the operation.
Very reliable: “Cloud” uses
measures such as multiple copies of data fault tolerance and sympathetic
interchangeability of computing nodes to ensure the reliability of the service.
Universally applicable: Cloud computing can
create versatile applications, and the same “cloud” can support
different operations at the same time.
Scalability: The size of the
“cloud” can be dynamically scaled to meet the needs of scale growth.
On-demand service: The cloud is a huge pool
of resources that users can purchase on-demand.
Low cost: The cloud has a low-cost
advantage, and its versatility and fault tolerance can reduce many expenses, so
enterprises do not have to bear high costs.
