Cloud computing in my eyes - PAAS (platform as a service)

As an academic researcher , The related major is geographic information , But computer science, in particular, has become related to us , But it is absolutely limited to those in the major , For a programmer like me, who is informal and formal , stay 2 Years ago, I only had a vague understanding of Cloud Computing , But as a person who specializes in technology , There is still a great lack of understanding of cloud computing or cloud native , My knowledge in this field is only a small part of doing something , Therefore, I can only explain the concept of the whole for you to understand ：

Cloud computing It refers to on-demand access through the Internet Calculation resources - application 、 The server （ Physical server and virtual server ）、 data storage 、 Development tools and network functions, etc , These resources are hosted by cloud Service provider （ or CSP） Managed remote data center . CSP Subscription fees will be charged monthly when providing these resources , Or charge according to the usage .

PaaS（ Platform as a service ） I only know something about this

PaaS Provide an on demand platform for software developers - Hardware 、 Complete software stack 、 Infrastructure , Even development tools , Used to run the 、 Develop and manage applications , It will not incur costs due to maintaining the platform internally , Bring problems such as complexity and inflexibility .

But with my professional knowledge and research, I continue to Google earth engine（GEE） and Microsoft planetary The gradual rise of two professional cloud computing platforms , I also gradually have some deeper understanding of my platform as a service , But the biggest help of this platform as a service is to provide free services to students and teachers in school , Compared with other domestic cloud platform services, they are also more widely used , This service can also be enjoyed by more people . I have written about the two platforms before , See the specific links .

Google Earth Engine（GEE）——GEE The most complete introduction （7000 Long writing ） The gospel of beginners ！_ This star bright blog -CSDN Blog _ Google gee Earth engine code editor code.earthengine.google.com The earth engine on (EE) The code editor is for the earth engine JavaScript API Web based IDE. The code editor function is designed to quickly and easily develop complex geospatial workflows . The code editor has the following elements （ Pictured 1 Shown ）：JavaScript The code editor is used to visualize the map display of geospatial datasets API Reference documents （ Document tab ） be based on Git Script manager （ Script tab ） Console output （ Console tab ） Task manager （ Task tab ） Handle long-running queries .https://blog.csdn.net/qq_31988139/article/details/119857470 Global real-time big data analysis platform Microsoft planetary computer （planetary computer）analytics lab +AI for earth!_ This star bright blog -CSDN Blog Microsoft is the world's best operating system , Now start to work on the cloud platform , And as an epic cloud platform monitoring , In the future, we can meet Google earth engine（GEE） Compete with , And in the near future , Cloud computing and AI The use of wisdom , It will play a very important role in the early warning of our global change monitoring , Now let's see ： Official promotional video ：https://innovation.microsoft.com/en-us/planetary-computer Microsoft's new planetary computer is providing the scientific community with a large amount of near real-time spatial data , And for in-depth 、 Protection related analysis provides tools ....https://blog.csdn.net/qq_31988139/article/details/118991271 As for domestic pie-engine The platform may be more of an imitation and transplantation , The feeling of using is limited , It doesn't feel very comfortable , And access to data is limited , therefore , The domestic commercial atmosphere is stronger .

PIE-engine Introduction to data sets in ： High score image , Fengyun data and shortcomings _ This star bright blog -CSDN Blog _ Cloud computing Data sets brief introduction PIE As the first cloud computing platform in China's geographic information , It's been open for a year , But now commercial services have begun , So different business operations are really for free GEE It's basically not comparable to , But there are many GEE Incomparable , Many domestic satellite data, such as high-score images ,PIE The data set links in are as follows ：PIE-Engine Remote sensing and geographic information cloud service platform (piesat.cn) High score image ：PIE-Engine Remote sensing and geographic information cloud service platform (piesat.cn)...https://blog.csdn.net/qq_31988139/article/details/121576104

The requirements for programming languages are basically universal JavaScript and python perhaps R Language ,python It is still the language of the above two platforms , But now for simplicity and visualization , I'm used to using GEE The online programming interface of the platform , This is a bit like the front-end and back-end operations are the same , Look at the code and results directly on the same interface , More direct and concise . As shown in the following figure .

As for the benefits of Cloud Computing , You know better than I do . To me, , stay Google On the earth engine , Processing data may take ten days and a half months on a computer with a very high local configuration , But on this platform, that is, things in minutes or even seconds , It is absolutely twice the result with half the effort , But open platforms and relatively customized services also need to write their own code .

The field of cloud computing is too broad , transcend 360 OK, today , Every walk is like a mountain , Cloud computing involves more and more fields , Cloud platform as a service is a kind of welfare for every individual , As long as you have an idea, it can be realized soon , So don't worry about the trouble caused by hardware equipment anymore .

I also hope that cloud computing can bring you more help .
