Google App Engine Paas Cloud Computing GOOGLE APP ENGINE PAAS CLOUD COMPUTING Google App Engine lets developers build scalable web and mobile backends in Services Ecosystem: Tap a growing ecosystem of GCP services from your app . Google cloud computing platform fees Google has set up Google App Engine to encourage its wide adoption. App Engine also features a dedicated Python runtime environment, which includes a fast Python interpreter and the Python standard library. A Web-based administration console: The console helps developers manage their applications. Core to this is the servlet 2. Ruby and C [6] are only available in the flexible environment. Each of these applications can use up to MB of storage, up to 5 million page views each month without an additional fee. No method for bulk downloading data from GAE using Java currently exists. App Engine packages those building blocks and provides access to scalable infrastructure that we hope will make it easier for developers to scale their applications automatically as they grow. Docker containerized applications can run on many types of infrastructure, such as Amazon Web Services , Microsoft Azure , and others. Restrictions[ edit ] Developers have read-only access to the filesystem on App Engine. Programming interfaces to support authenticating users and sending email by using Google Accounts Scheduled tasks for triggering events at specified times and regular intervals This is essentially the same platform that Google uses to build its own software. Apache Struts 1 is supported, and Struts 2 runs with workarounds. As with most cloud-hosting services, with App Engine, you only pay for what you use. Web2py web framework offers migration between SQL Databases and Google App Engine, however it doesn't support several App Engine-specific features such as transactions and namespaces. The customer pays for storage and bandwidth. For example, there is no charge for a developer to build an application. Does not support sticky sessions a. Java runtime: Google added Java as a second supported programming language platform. A customer is allowed to register up to ten applications per developer account. This offers an alternative to using threads for parallel data processing. With App Engine, your application is not hosted on a single server. Extensions to these quotas can be requested, and application authors can pay for additional resources. Google levies no set-up costs and no recurring fees. GQL does not support the Join statement. Just as servicing a Google search request may involve dozens, or even hundreds of Google servers, all totally hidden and satisfied in a fraction of a second, Google App Engine applications run the same way, on the same infrastructure. Developers will be able to register up to three applications. After a customer deploys that application, however, the charges begin to add up. Google development stack and cloud computing In addition to these infrastructure tools, Google App Engine also includes a development stack. Google has said that it plans to support more languages in the future, and that the Google App Engine has been written to be language independent. Google calls this a scalable serving infrastructure that connects the Web application code to the Google environment. Application developers have access to persistent storage technologies such as the Google File System GFS and Bigtable, a distributed storage system for unstructured data. Google says its vision with Google App Engine is to offer developers a more holistic, end-to-end solution for building and scaling applications online. Users may upload arbitrary Python modules, but only if they are pure-Python; C and Pyrex modules are not supported. Applications can use only virtual filesystems, like gae-filestore. The first one that Google supported was Python, a high-level programming language that makes it easier to rapidly build complex applications with minimal programming. This is one of Google's answers to the portability concern. The Java version supports asynchronous nonblocking queries using the Twig Object Datastore interface. For Dummies: The Podcast..

  • Framework-Specific Modeling Languages
    Framework-Specific Modeling Languages by MichalAntkiewicz A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Electrical and Computer Engineering Waterloo, Ontario, Canada, 2008 c Micha lAntkiewicz 2008 ISBN: 978-0-494-43232-7 I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. Micha lAntkiewicz ii Abstract Framework-specific modeling languages (FSMLs) help developers build applications based on object-oriented frameworks. FSMLs formalize abstractions and rules of the framework's application programming interfaces (APIs) and can express models of how applications use an API. Such models, referred to as framework-specific models, aid developers in understanding, creating, and evolving application code. We present the concept of FSMLs, propose a way of specifying their abstract syntax and semantics, and show how such language specifications can be interpreted to provide reverse, forward, and round-trip engineering of framework-specific mod- els and framework-based application code. We present a method for engineering FSMLs that was extracted post-mortem from the experience of building four such languages. The method is driven by the use cases that the FSMLs under development are to support. We present the use cases, the overall process, and its instantiation for each language. The presenta- tion focuses on providing concrete examples for engineering steps, outcomes, and challenges. It also provides strategies for making engineering decisions.

  • Proceedings of the IEEE Visweek Workshop on Visual Analytics in Healthcare: Understanding the Physicians Perspective
    Proceedings of the IEEE VisWeek Workshop on Visual Analytics in Healthcare: Understanding the Physicians Perspective October 23rd, 2011 Providence, RI www.visualanalyticshealthcare.org Sponsors: ! Preface Visualization and visual analytics show great potential as methods to analyze, filter, and illustrate many of the diverse data used in clinical practice. Today, (a) physicians and clinical practitioners are faced with the challenging task of analyzing large amount of unstructured, multi-modal, and longitudinal data to effectively diagnose and monitor the progression of a particular disease; (b) patients are confronted with the difficult task of understanding the correlations between many clinical values relevant to their health; and (c) healthcare organizations are faced with the problem of improving the overall operational efficiency and performance of the institution while maintaining the quality of patient care and safety. Visualization and visual analytics can potentially provide great benefits to each of these three core areas of healthcare. However, to be successful, the resulting visualization must be able to meet the physician’s requirements and be useful for both patients and physicians. Despite the continuous use of scientific visualization and visual analytics in medical applications, the lack of communication between engineers and physicians has meant that only basic visualization and analytics techniques are currently employed in clinical practice. The goal of this workshop is to gather together leading physicians and clinical practitioners to share with the visualization community their need for specific visualization tools and discuss the areas in healthcare where additional visualization techniques are needed.

  • Comparative Study on Python Web Frameworks: Flask and Django
    Devndra Ghimire Comparative study on Python web frameworks: Flask and Django Metropolia University of Applied Sciences Bachelor of Engineering Media Engineering Bachelor’s Thesis 5 May 2020 Abstract Devndra Ghimire Author(s) Comparative study on Python web frameworks: Flask and Title Django. Number of Pages 37 pages + 0 appendices Date 5 May 2010 Degree Bachelor of Engineering Degree Programme Media Engineering Specialisation option Software Engineering Instructor(s) Kari Salo, Senior Lecturer The purpose of the thesis was to the study the various features, advantages, and the limita- tion of two web development frameworks for Python programming language. It aims to com- pare the usage of Django and Flask frameworks from a novice point of view. The theoretical part of the thesis presents the various types of programming languages and web technolo- gies. In the practical part, however, the study is divided into two parts, each part observing the respective web application framework. In order to perform the comparison, a social network and eCommerce like application was built for Flask and Django respectively. The comparison was started by developing the social network application first with Flask and finished with the e-commerce application using Django. Python programing language, SQLite database for the backend and HTML, JavaS- cript, and Ajax were used for the frontend technology. At the end of the project, both appli- cations were deployed to the cloud platform called Heroku. After the comparison, it was found that the most significant advantages of Flask were that it provides simplicity, flexibility, fine-grained control and quick and easy to learn. On the other hand, Django was easy to work with because of its extensive features and support for librar- ies.
