performance

More efficient than traditional methods , More savings , A more stable , More convenient advantages .

Two 、 The present and past life of cloud

2.1 What is cloud

The cloud concept refers to computers 、 mobile phone 、 TV and other electronic application products can provide cloud services through the Internet 、 Cloud space 、 Cloud search 、 Cloud browsing 、 Cloud community 、 A series of resource sharing applications such as Cloud Applications .

Cloud services are based on “ Cloud computing ” technology , Realize the interconnection between various terminal devices . mobile phone 、 TV is just a simple display and operation terminal , They no longer need to have strong processing power . Like the online antivirus we often use 、 Network hard disk 、 Online music and so on belong to cloud services .

So what's in here 3 A concept ：

cloud : Popular understanding is remote computer , And it's a group a pile , These remote computers work together to build a platform , Providing services to users
Calculation ： This is a very conceptual term , It can be regarded as the computational power of calculating and analyzing business data , But in the popular sense , Computing refers to the various requirements for building business systems
platform ： Will cloud （ Remote hardware resources ） And calculation （ Remote software resources ） Put together , It forms a platform , Provide various services to users .

We can think of it this way : Cloud platform Namely A platform on the cloud , Provide users with a variety of long-range service

2.2 The basic principle of cloud

By distributing computing across a large number of distributed computers , Not on a local computer or remote server , The operation of enterprise data center will be more similar to that of Internet . This enables the enterprise to switch resources to the required applications , Access computers and storage systems as required .

2.3 What is Cloud Computing

What is Cloud Computing ？ Cloud computing as a new resource , It has strong practicality and delivery mode , Gradually recognized by academia and industry , It is a kind of Distributed Computing , A group of loosely coupled computers form a super virtual computer , It is often used to perform some large tasks , Through the network “ cloud ” Will be huge data , The handler is divided into countless small programs , These resources are shared by all cloud computing users , And can be easily accessed through the network , Process and analyze these applets , Get the result and return it to the user , Cloud computing at this stage through continuous progress , It is not just a separate calculation , It is the result of the mixed evolution and leap of various computer technologies .

2.4 Cloud native Computing Foundation

Mention cloud , It must be said that the cloud native Computing Foundation （Cloud Native ComputingFoundation, CNCF）,CNCF Founded on 2015 year 12 month 11 Japan ,CNCF At the beginning of its establishment, there were only more than a dozen founding members , Including Google 、IBM、Red Hat、VMware…… After several years of development , at present CNCF There has been more than 300 Members , Covering well-known at home and abroad IT manufacturer , Including Microsoft 、 Amazon 、 Apple 、 Alibaba 、 HUAWEI, etc. .

2.5 Classification of cloud platforms

There are major cloud platforms 2 Categories: , Namely :

Private cloud platform

Private cloud platform , Private cloud for short , As the name suggests, it is a private cloud platform , Generally, enterprises build their own , Provide it for internal use . Such as , Various business departments Or each project team as a customer , Buy resources from the platform , Or apply for resources to use , Expenses are generally settled within the enterprise . It is a way to improve Utilization of resources , meanwhile , Based on various services provided on the cloud platform , It also facilitates the internal development of the enterprise . But for the enterprise itself , Its hardware resources are self-organized .( Such as Build your own computer room Self purchase server, etc )

Public cloud platform

Public cloud platform is a cloud platform provided to the public . anybody Or any enterprise You can go to... In the public cloud platform Buy apply Corresponding resources . For providers of public cloud platforms , Its own hardware resources are self-organized ( Such as self built computer room , Self purchase server , Building data centers )

2.6 The role of cloud primordial

For the application development team , Cloud native technology can improve the efficiency of application development , Improve the quality of application delivery . For example, through containers , The technology development team can more easily obtain the environment and resources needed for development , The developed applications can be more easily deployed and managed by the operation and maintenance team .

For the business side , The benefit of cloud native is the submitted requirements , Can be responded to and implemented faster . Because cloud native technology can effectively shorten the application delivery cycle , Make requirements code faster , Code becomes an online application faster , Finally, serving the users , Realize the value of

2.7 Cloud native development

After several years of development , The concept of cloud Nativity has been recognized by the community 、 Widely recognized by enterprises and the market . From the current popular cloud native technology , Cloud native has been used in many industries and fields , There are many cases of landing , Including high technology 、 Finance 、 manufacture 、 retail 、 education 、 The government , Even military and so on .

2.8 Three services of the cloud

IaaS

Infrastructure as a Service: Infrastructure as a service , It means that IT Infrastructure is provided as a service

VPS：virtual private server

network bandwidth

VPC：virtual private cloud（ A small private cloud within a large public cloud , It's a private intranet on the cloud ）

PaaS

Platform as a Service : Platform as a service . It refers to providing the platform as a service . So the cloud platform we want to learn , It's a kind of PaaS service . Others are like

Tencent map development platform

Applet development platform

Distributed file storage platform

Distributed cache service platform

etc.

SaaS

Software as a Service: Software as a service , It refers to the provision of software as a service .

Portal site

Mobile application

Interactive application

Website content management

etc.

3.3 The difference between cloud database and traditional database

project	Traditional software usage	Cloud Computing
How to get software	Invest in the construction of computer room , Build a hardware platform , Buy software and install it locally	Directly purchase the software services of cloud computing manufacturers
Usage mode	Local installation , Local use	The software runs on the servers of cloud computing manufacturers , Users can use software services through the network wherever there is a network connection
Payment method	A large initial investment cost needs to be paid at one time , Including the construction of computer room 、 configure hardware 、 Buy all kinds of software ( operating system 、 Antivirus software 、 Business software, etc )	Zero cost investment can immediately obtain the required IT resources , Just pay for the resources you use , Use more, pay more , Use less and pay less , Extremely cheap
Maintenance cost	You need to hire professional technicians at your own expense to maintain	Zero cost , Cloud computing vendors are responsible for all maintenance work
get IT Speed of resources	It takes a long time to build the computer room 、 Purchase, install and commission equipment and systems	Ready to use , Available immediately after purchase
How to share	Build your own , Provide for oneself	After cloud computing manufacturers build cloud computing service platforms, they provide services for many users at the same time
Maintenance speed	There is a virus 、 When the system crashes , You need to hire yourself IT Personnel maintenance , Many ordinary enterprises IT Limited technical capacity of personnel , Encounter some problems and even need to find foreign aid , Usually it can't be solved immediately	In case of any system problems , Cloud computing manufacturers will give timely response with their professional team , Ensure the normal use of cloud services
Resource utilization	Low utilization , Invested a lot of money to build IT System , Often only for the enterprise's own use , When businesses don't need so much IT Resource time , There will be a waste of resources	High utilization rate , It can provide services for a large number of users every day ; When there are idle resources , The cloud computing management system will automatically shut down and exit redundant resources ; When additional resources are needed , It will automatically start and add relevant resources
The cost of enterprise relocation	When the enterprise moves , The original computer room facilities will be invalidated , It is necessary to re invest in a new place and build a computer room at a high cost	No matter where the enterprise moves , You can get cloud computing services immediately at zero cost through the network , Because resources are in the cloud , Not on the client side , The relocation of enterprises will not affect IT Distribution of resources
Resource scalability	Built by the enterprise itself IT The service capacity of infrastructure is usually capped , When the business volume of the enterprise increases suddenly , The existing IT Infrastructure cannot meet demand immediately , It takes time and money to buy and install new equipment : When the business peak is over , The extra equipment will be idle , Waste of resources	Metacomputing manufacturers can provide enterprises with almost unlimited IT resources （ Resources such as storage and Computing ）, Enterprises can get as much as they want ; When the enterprise does not use , Just unsubscribe from excess resources , There is almost no problem of idle resources .
