摘要

功能即服务（FaaS）范式提供了一种无服务器的方法，它抽象了底层基础设施的管理，使开发人员能够专注于应用程序逻辑。然而，利用感知基础设施的特性可以进一步优化无服务器性能。我们提出了一个软件原型，它增强了Apache OpenWhisk无服务器平台，采用了一种新的架构，其中包含tAPP（拓扑感知分配优先级策略），tAPP是一种用于指定拓扑感知调度策略的声明性语言。通过一个涉及跨多个云区域的分布式数据访问的案例研究，我们表明，与标准的OpenWhisk实现相比，tAPP可以显着减少延迟并最大限度地减少性能变化。

tAPP OpenWhisk: A serverless platform for topology-aware allocation priority policies

The Function-as-a-Service (FaaS) paradigm offers a serverless approach that abstracts the management of underlying infrastructure, enabling developers to focus on application logic. However, leveraging infrastructure-aware features can further optimize serverless performance.

We present a software prototype that enhances Apache OpenWhisk serverless platform with a novel architecture incorporating tAPP (topology-aware Allocation Priority Policies), a declarative language designed for specifying topology-aware scheduling policies. Through a case study involving distributed data access across multiple cloud regions, we show that tAPP can significantly reduce latency and minimizes performance variability compared to the standard OpenWhisk implementation.
