Ci/cd from hardware programming to software platform

Hardware programming

When we are designing single hardware , It mainly uses commands to control the status of hardware switches , Then let the hardware have specific capabilities , Such as Storage capacity / Operational capability / Visualization, etc . At this time, it is to complete the arrangement of instructions on a specific hardware development platform . How do developers confirm these instructions ？ Whether it's .net、java、golang, When they are doing cross platform adaptation , Will provide instruction adaptation to the corresponding platform . In recent years, Chuangxin projects , When migrating a software platform to a specific hardware platform , A large number of hardware instruction adaptation .

Hardware abstraction

After abstracting hardware instructions , Form a programmable microkernel , That is, the hardware instruction set of the operating system . After the instruction set forms a systematic specification , The microkernel abstracts the hardware instruction set , Let peripheral applications interact only with the kernel . If new hardware appears , The microkernel adaptation will be improved again , Finally, hardware access . When there is programmable API After the interface , Hardware and software will interact independently based on specific protocols , There is no longer a strong correlation .

Software programming

be based on OSI7 Layer model and tcp/ip Four layer model , Software programming mainly refers to socket Connection and programming based on specific application platform business .

Now popular web Programming is mainly based on specific middleware to provide the programming of the business implementation part , Like facing servlet The standard java web Development , be based on IIS Waiting .net web Realization , Or based on specific web Business implementation of middleware , Such as python/golang etc. web Development .

Based on the present IT Integrity of basic services , We will use a lot of basic Middleware in software programming , Provide support services for our business implementation , Such as data storage services ：【 database /FTP/ Object model, etc 】, Or basic data development platform , Specific middleware drivers socket The connection is encapsulated , We only focus on what specific middleware drivers provide api that will do .

But on the whole , Software editing is osi Wait for the model socket Business implementation after encapsulation .socket It provides software with cross machine interconnection capability .

Cloud hardware resources

socket Connection handles are limited in specific hardware . If software is dynamic to hardware resources , We need to build a hardware resource pool to cope with the application's support for resources . Hardware service capabilities are abstracted as resources , Uniformly register to the cloud management platform , The application adopts the declaration system for the use of application resources during deployment , Finally, the cloud management platform completes the automatic deployment and monitoring of applications , According to the application's declaration of resources, find the resources in the hardware resource library that meet the declaration and occupy , And automatically complete the application deployment .

Cloud management platform

Hardware resources are static , Whether to be online depends on the actual situation , It is dynamic in the time dimension . The hardware cloud management platform is a set of management software , Mainly by the resource registry / Application release scheduling center / Hardware resource agent service / Hardware resource virtualization （ Containerization ） And so on . Cloud management platform is a centralized application platform , The master platform manager registers all application resources / Dynamic monitoring / Recycling / Application deployment, etc . The cloud management platform releases the hands of the implementation team , Let automated tools do most of the work .

Business system cloud requirements

The business system needs to go through multiple processes from R & D to application 、 And it happens repeatedly . Such as ： Demand sorting / Code implementation / A functional test / Integration testing / Application packaging / Application publishing and deployment .

Under normal circumstances, multiple environments are required ： development environment / Test environment / Quasi production environment / Production environment .

So many environments , How to ensure consistency ？ Cloud deployment just solves these problems . Declarative acquisition of resource information , Make the running environment universal . Automated deployment of cloud environments , Make the deployment of application environment more flexible 、 intelligence . And realize ci/cd And other standard processes , Let the code detect / automated testing / Version return / Grayscale publishing has become a reality ...............................
