As scalable information technology evolves to a more cloud-like model, digital assets (code, data and software environments) increasingly require curation as web-accessible services. "Service-izing" digital assets consists of encapsulating assets in software that exposes them to web and mobile applications via well-defined yet flexible, network accessible, application programming interfaces (APIs). In this paper, we postulate that recent advances in cloud computing make cloud platforms as-aservice (PaaS) ideal for deployment, lifecycle management, and policy-based control -i.e. API governance -for extant and future digital assets. Toward this end, we overview API governance as a PaaS technology and outline some early results generated by our investigation of a prototype we are developing, called EAGER, for implementing API governance at scale.

In this paper we present our vision for a two-level, distributed resource allocator that preserves fairness and satisfies deadlines of low latency workloads in a multi-cloudlet environment with offloading support. We analyze the opportunities and challenges that offloading and the multi-cloud environment impose and we suggest the changes required to a fair-preserving and deadline-driven resource allocator originally designed for resource-constrained environments.

Abstract-This paper presents SuperContra -a Design-byContract (DbC) framework that can ship with future PaaS offerings to enforce lightweight contracts across different programming systems, as-a-service. SuperContra is unique in that developers employ a familiar, high-level language to write contracts regardless of the programming language used to implement the component under test. We evaluate SuperContra using widely used, open-source software and compare its performance against existing DbC frameworks. Our results show that SuperContra performs on par with non-service-based DbC approaches and in some cases similarly to code running without contracts.
