主流云服务商不断地推出 Serverless 相关的云产品和新功能,其中华为云对Serverless在高效、高密度调度优化方面深入探索后,推出函数即服务(Function-As-A-Service)产品-FunctionGraph,作为华为云全域Serverless的核心产品,其覆盖边缘计算、车联网、AI应用等场景,此次揭秘华为云Serverless 30%+ 利用率提升的探索历程。 1、Se...
首先,超分很有可能导致性能下降从而违背QoS(Quality-of-Service),常见的作法是通过预测性能以避免违背QoS,这将在调度路径上引入模型推理,而预测精度越高意味着计算复杂,从而调度开销越大,简单的计算却难以有效保证QoS,存在预测精度与调度开销之间的权衡;其次,当负载波动时,为了快速释放空闲实例资源,需要更敏感的自动扩容...
Create event-driven, scalable serverless applications in .NET, Node.js, Python, Java, or PowerShell with the Azure Functions app— a serverless computing service.
IT是一个永远都不消停的行业,在这个行业里不断有各种各样新的名词和技术诞生,云计算(Cloud Computing)的出现是21世纪IT业界最重大的一次变革。云计算的发展从基础架构即服务(Infrastructure as a Service, IaaS),平台即服务(Platform as a Service,PaaS),软件即服务(Software as a Service,SaaS),慢慢开始演变到...
Serverless is more than function as a service (FaaS)—thecloud computing service that enables developers to run code or containers in response to specific events or requests without specifying or managing the infrastructure required to run the code. ...
the expansion of the team size, the tightly coupled approach of the monolithic architecture will bring more and more problems, and the flexibility and scalability of the architecture has become a major challenge that hinders the development of the business. The microservice architecture came into ...
Put simply, Serverless computing = FaaS + BaaS. In our definition,for a service to be considered serverless, it must scale automatically with noneed for explicit provisioning, and be billed based on usage.可以看到，从 IaaS 到 FaaS 再到 SaaS，再到如今的 Serverless，云计算的发展在近十余年中...

Web service会首先从热队列中取出一个container message,这代表着如果先前该function已经运行过了留下来的container,就不用再去创建一个新的(类似于线程池的核心线程) 如果需要执行的function的热队列没有container,web service从冷队列中取出一个container message来分配一个空置的container来运行这个function,运行完后conta...
Serverless computing200 XP 6 minutes In the early days of cloud computing, cloud service providers such as Amazon and Microsoft focused on offering a rich assortment of IaaS services to their customers. This fueled the growth of public clouds by allowing customers to rather easily shift workloads ...
