• Authors: Pawissanutt Lertpongrujikorn, Mohsen Amini Salehi,
• Abstract summary: We propose a new paradigm, known as Object as a Service (O) that encapsulates application data and functions into the cloud object abstraction. O relieves developers from resource and data management burden while offering built-in optimization features. We develop a platform named Oparaca that offers state abstraction for structured and unstructured data with consistency and fault-tolerant guarantees.

• Abstract: The function-as-a-service (FaaS) paradigm is envisioned as the next generation of cloud computing systems that mitigate the burden for cloud-native application developers by abstracting them from cloud resource management. However, it does not deal with the application data aspects. As such, developers have to intervene and undergo the burden of managing the application data, often via separate cloud storage services. To further streamline cloud-native application development, in this work, we propose a new paradigm, known as Object as a Service (OaaS) that encapsulates application data and functions into the cloud object abstraction. OaaS relieves developers from resource and data management burden while offering built-in optimization features. Inspired by OOP, OaaS incorporates access modifiers and inheritance into the serverless paradigm that: (a) prevents developers from compromising the system via accidentally accessing underlying data; and (b) enables software reuse in cloud-native application development. Furthermore, OaaS natively supports dataflow semantics. It enables developers to define function workflows while transparently handling data navigation, synchronization, and parallelism issues. To establish the OaaS paradigm, we develop a platform named Oparaca that offers state abstraction for structured and unstructured data with consistency and fault-tolerant guarantees. We evaluated Oparaca under real-world settings against state-of-the-art platforms with respect to the imposed overhead, scalability, and ease of use. The results demonstrate that the object abstraction provided by OaaS can streamline flexible and scalable cloud-native application development with an insignificant overhead on the underlying serverless system.

  Histrio is a programming model and execution environment that simplifies the development of stateful applications. It lifts concerns such as state management, database interaction, and programming handling from developers. It guarantees exactly-once-processing consistency, meaning that the application always behaves as if any interaction with external clients was processed once and only once.

• Managing Cold-start in The Serverless Cloud with Temporal Convolutional Networks [0.0]
  Serverless cloud is an innovative cloud service model that frees customers from most cloud management duties. A big threat to the serverless cloud's performance is cold-start, which is when the time of provisioning the needed cloud resource to serve customers' requests incurs unacceptable costs to the service providers and/or the customers. This paper proposes a novel low-coupling, high-cohesion ensemble policy that addresses the cold-start problem at infrastructure- and function-levels of the serverless cloud stack.

  Traditional outsourcing requires uploading device data to the cloud server. We propose to leverage widely available open-source data, which is a massive dataset collected from public and heterogeneous sources. We develop a novel strategy called Efficient Collaborative Open-source Sampling (ECOS) to construct a proximal proxy dataset from open-source data for cloud training.

We present Teiresias, comprising i) a workflow pattern for scalable discovery of personal data at rest, and ii) a cloud native system architecture and open source prototype implementation of said workflow pattern.
