Streamlining Cloud-Native Application Development and Deployment with Robust Encapsulation

TL;DR

This paper introduces Object-as-a-Service (OaaS), a novel serverless paradigm that encapsulates logic, data, and requirements into a single package, simplifying cloud-native app development and improving performance and reliability.

Contribution

The paper proposes OaaS, a provider-agnostic, object-oriented serverless model with a declarative interface for non-functional requirements, realized through the Oparaca platform.

Findings

Oparaca enhances application performance by 60X.

It improves reliability by 50X.

Reduces development and deployment effort significantly.

Abstract

Current Serverless abstractions (e.g., FaaS) poorly support non-functional requirements (e.g., QoS and constraints), are provider-dependent, and are incompatible with other cloud abstractions (e.g., databases). As a result, application developers have to undergo numerous rounds of development and manual deployment refinements to finally achieve their desired quality and efficiency. In this paper, we present Object-as-a-Service (OaaS) -- a novel serverless paradigm that borrows the object-oriented programming concepts to encapsulate business logic, data, and non-functional requirements into a single deployment package, thereby streamlining provider-agnostic cloud-native application development. We also propose a declarative interface for the non-functional requirements of applications that relieves developers from daunting refinements to meet their desired QoS and deployment constraint targets. We realized the OaaS paradigm through a platform called Oparaca and evaluated it against various real-world applications and scenarios. The evaluation results demonstrate that Oparaca can enhance application performance by 60X and improve reliability by 50X through latency, throughput, and availability enforcement -- all with remarkably less development and deployment time and effort.
