In this issue, the editor will bring you about the use of serverless cloud functions. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

Serverless is a new hot spot in the industry. Serverless cloud functions allow users to go online and operate without worrying about the deployment and operation of the server, as long as they develop the core business logic, with distributed disaster recovery capability, and can automatically expand and scale according to the load, and charge according to the actual number of calls and duration.

The use of serverless cloud functions

Serverless cloud functions help users run code without purchasing and managing servers. Users only need to write the core code and set the conditions for the code to run in the language supported by the cloud platform, so that the code can run flexibly and securely on the cloud infrastructure, and can completely manage the underlying computing resources, including server CPU, memory, network, code deployment, auto scaling, load balancing and other services.

Compared with CVMs, cloud functions are more suitable for supporting micro-service architecture business scenarios. Take the multi-specification image compression service as an example, when a user uploads an image to COS, it automatically compresses the original image into a variety of sizes such as mobile phone, tablet, computer and so on.

For example, to implement the service using cloud function, users only need to create a function, define the trigger condition of the function as "image upload", edit it online or upload it after code writing using IDE, and the service will be built. When a user uploads an image, the defined function is automatically called to complete the multi-specification compression of the image. The cloud function platform automatically expands and shrinks the function instance according to the upload concurrency, and is finally billed according to the actual call consumption.

Benefits of serverless cloud functions

The use of serverless cloud functions will eliminate all operation and maintenance operations, and enterprises and developers can focus more on the development of core business, achieve rapid launch and iteration, and grasp the pace of business development.

Cloud function attempts to extract business algorithms and processes for users to implement, to open up various cloud services, and to achieve general features such as load balancing, automatic scaling, fault disaster recovery, security supervision and other general features. It really enables users to build personalized services like building blocks, reducing business launch time from sky-level to minute-level.
