Abstract: At this year's "2017 Hangzhou Yunqi Conference", Alibaba Cloud's function computing has been upgraded again: function computing has opened up several important cloud product lines, and can directly connect to table storage, API gateway, and log services. Users can flexibly and conveniently combine various business scenarios with only simple configuration.
In the past ten years, cloud services have profoundly changed the way society acquires and uses computing power. Cloud services themselves have also evolved at an extremely fast rate, and new service forms have been emerging. Serverless computing is one of them. Alibaba Cloud Function Compute is an event-driven serverless computing service. Users only need to write and upload the code, and Function Compute will execute the code in a reliable and safe manner, and the system can be smoothly scaled as the traffic increases. Function Compute has built-in event sources for connecting multiple products. Function Compute can be triggered by events or directly invoked through HTTP requests. The invocation method is simple and convenient.
Alibaba Cloud's function computing is an elastic mass computing platform based on the theoretical framework of serverless, which is an implementation of the serverless framework. The main theme of function computing is light, fast, flexible, and millisecond billing. It faces too much system coupling. Strong, difficult to upgrade and maintain; low utilization of hardware resources; no real-time elastic expansion; developers need to pay attention to the software + hardware environment; high operation and maintenance costs make users feel very embarrassed and headaches.
It is understood that Alibaba Cloud's function computing is the first event-driven serverless computing platform in China. Users can call and pay on demand, and there is no need to manage infrastructure such as servers. It is especially suitable for application scenarios with small coupling and obvious peaks and valleys. Enterprise application use.
Generally speaking, Alibaba Cloud Function Compute is mainly suitable for scenarios with few business dependencies, scenarios with peaks and troughs in traffic, and scenarios that require elastic expansion, scenarios triggered by events, and scenarios that are released after use and require high resource utilization. are more suitable.
函数计算作为国内这个领域的领导者，阿里云此次强势发挥两大核心技术优势：虚拟机级别的安全隔离、毫秒级别的计量数据，大幅提升产品性能的同时也让用户计算成本降低30%左右，同时还联通了API网关、对象存储、表格存储、日志服务等多款产品，大幅降低学习成本，在控制台上提供多组用户场景的模板供用户选择，例如爬虫系统、图片处理、API网关对接、连接云市场、对象存储触发事件、图像分类、人脸识别等模板。
阿里云的函数计算操作起来也十分方便，只需五步就可以轻松执行一个代码。第一步，开通函数计算产品。第二步，开通成功后，点击进入控制台，选择程序运行的区域。第三步，选择新建服务，输入服务名称和功能描述。第四步，创建函数，可以通过空白函数来创建，也可以通过模板文件创建。第五步，点击执行，即可看到代码执行结果和代码编辑框。
函数计算适合的业务场景非常广泛，目前主要集中在多媒体行业、视频行业、物联网行业、在线教育、游戏行业以及传统IT行业，主要帮助用户执行图片处理、数据处理、API网关的后端服务、物联网设备的后端服务以及大数据的一些处理等。
截止到目前，阿里云已经实现了全球最完整的计算家族，覆盖从轻量级到高性能计算的全场景。
