Learn the five skills you need to master in cloud computing application development

Before learning cloud computing application development , Let's first understand what cloud computing is .
Baidu Encyclopedia of Cloud Computing ： Cloud computing （cloud computing） It's a kind of distributed computing , It means through the Internet “ cloud ” It's a huge amount of data processing programs , then , Through the system composed of multiple servers, these small programs are processed and analyzed, and the results are returned to the user . The early days of Cloud Computing , In short , It's simple distributed computing , Solve task distribution , And merge the calculation results . thus , Cloud computing is also called grid computing . Through this technology , In a very short time （ Seconds ） Complete the processing of tens of thousands of data , So as to achieve strong network services .
At this stage, cloud service is not only a kind of distributed computing , It's distributed computing 、 Utility calculation 、 Load balancing 、 Parallel computing 、 Network storage 、 The result of the hybrid evolution and leap of computer technologies such as hot backup redundancy and virtualization .

Skill 1 ： Common programming languages

• Now commonly used popular programming languages Java、Perl、Python、C#、Go It covers the foundation of cloud computing application development , We need to master one or more languages to become a sharp weapon for our application of Cloud Computing , If there is no foundation , How to talk about cloud computing ？ The foundation is not solid , The earth trembled and the mountains swayed ！
• Mastering one language and then learning other languages can get started quickly , For example, you now master JAVA, So you're learning Python and **C#** It's very simple when , The grammatical structure is similar , It's all object-oriented programming .
• If you want to learn cloud computing application development , These languages are best learned , For better operation in the back .

I won't introduce each language in detail here , All friends learn by yourselves , Here is a brief talk about the skills needed to learn cloud computing application development .

Skill 2 ：Kubernetes

Baidu Encyclopedia ：

• abbreviation K8s, Yes, it is 8 Replace the middle of the name 8 Characters “ubernete” An abbreviation of . It's an open source , It is used to manage containerized applications on multiple hosts in the cloud platform ,Kubernetes The goal is to make the deployment of containerized applications simple and efficient （powerful）,Kubernetes Provides application deployment , planning , to update , A mechanism of maintenance .
• Kubernetes yes Google An open source container choreography engine , It supports automated deployment 、 Large scale scalability 、 Apply containerization Management . When you deploy an application in a production environment , It is usually necessary to deploy multiple instances of the application in order to load balance the application requests .
  stay Kubernetes in , We can create multiple containers , Each container runs an application instance , Then through the built-in load balancing strategy , Realize the management of this group of application instances 、 Find out 、 visit , And these details do not require the operation and maintenance personnel to carry out complex manual configuration and processing .

Skill 3 ：Docker

Baidu Encyclopedia ：
Docker Is an open source application container engine , Allows developers to package their applications and dependencies into a portable container , Then post to any popular Linux or Windows On the machine with the operating system , You can also implement virtualization , Containers are completely sandboxed using the sandbox mechanism , There will be no interface between them .

Skill 4 ： Network engineering

Since it is cloud computing, there is no shortage of Internet , We need to learn about network engineering , The following is the relevant knowledge of network engineering , Friends can inquire and learn according to their own needs .

• Basic knowledge of network operating system ;
• Design and development method of computer application system ;
• Basic knowledge of data communication ;
• Basic knowledge of system security and data security ;
• The basic technology of network security and the main security protocols and security systems ;
• Basic principles of computer network architecture and network protocol ;
• Standardization knowledge related to computer network ;
• LAN networking technology , Understand the basic technologies of man and WAN ;
• Computer network interconnection technology ;
• TCP/IP Networking method of protocol network and network application service technology ;
• Access network and access technology ;
• Basic principles and operation methods of network management ;
• Performance test and optimization technology of network system , And reliability design technology ;
• Basic principle and technology of network application ;
• New network technology and its development trend ;

Skill 5 ： data storage —— Relational databases are related to non relational databases

Relational database , A database that uses a relational model to organize data , It stores data in the form of rows and columns , To make it easy for users to understand , This series of rows and columns in a relational database is called a table , A set of tables makes up the database . A common relational database consists of Oracle,MySQL,SqlServer.
Non relational database Also known as NoSQL, Different from relational databases , They don't guarantee the ACID characteristic . common NoSQL Yes Redis, Voldemort, MogoDB.
Now many companies use Redis As a cache database server , Widely applied , I suggest you study hard Redis, It is very helpful for learning cloud computing later .
