AppScale: Scalable and Open AppEngine Application Development and Deployment
نویسندگان
چکیده
We present the design and implementation of AppScale, an open source extension to the Google AppEngine (GAE) Platform-asa-Service (PaaS) cloud technology. Our extensions build upon the GAE SDK to facilitate distributed execution of GAE applications over virtualized cluster resources, including Infrastructure-as-a-Service (IaaS) cloud systems such as Amazon’s AWS/EC2 and Eucalyptus. AppScale provides a framework with which researchers can investigate the interaction between PaaS and IaaS systems as well as the inner workings of, and new technologies for, PaaS cloud technologies using real GAE applications.

AppScale: Open-Source Platform-As-A-Service
AppScale is a scalable, distributed, and fault tolerant cloud runtime system that we have developed at the University of California, Santa Barbara as part of our research into the next generation of programming systems [5, 3]. In particular, AppScale is a cloud platform, i.e. a platform-as-a-service (PaaS) cloud fabric, that executes over cluster resources. The cluster resources underlying AppS...
متن کاملHybrid Cloud Support for Large Scale Analytics and Web Processing
Platform-as-a-service (PaaS) systems, such as Google App Engine (GAE), simplify web application development and cloud deployment by providing developers with complete software stacks: runtime systems and scalable services accessible from well-defined APIs. Extant PaaS offerings are designed and specialized to support large numbers of concurrently executing web applications (multi-tier programs ...
متن کاملNorth by Northwest: Infrastructure Agnostic and Datastore Agnostic Live Migration of Private Cloud Platforms
Cloud technology is evolving at a rapid pace with innovation occurring throughout the software stack. While updates to Software-as-a-Service (SaaS) products require a simple push of code to the production servers or platform, updates to the Infrastructure-as-a-Service (IaaS) or Platform-as-a-Service (PaaS) layers require more intricate procedures to prevent disruption to services at higher abst...
متن کاملKey-Value Datastores Comparison in AppScale
We present a simple framework that employs a single API – the Datastore API from the Google App Engine cloud computing platform – to interface to different open source distributed database technologies in use today. We use the framework to “plug in” different databases to the API so that they can be used by web applications and services without modification. The system facilitates empirical eva...
متن کاملActive Cloud DB: A Database-Agnostic HTTP API to Key-Value Datastores
In this paper, we present a technique that connects web applications to cloud-based distributed datastore technologies that implement the Google App Engine cloud datastore API. We implement our approach as a Google App Engine (GAE) application that we employ to expose the GAE datastore API to developers – for use with any language and framework. We evaluate this application on both GAE and over...
