Appscale 1.5 releases Open source scalable PAAs cloud computing platform

Appscale 1.5 This version supports bulk loaders, uploading and downloading your data. Java and Python application servers have been upgraded to 1.4.3. Support for Go App engine applications (SDK version 1.5.0), including supporting applications using multiple processes. All services (Process monitoring and recovery) are almost fault tolerant. An API channel for Python (which can also use multiple receivers) is implemented through Strophe.js. A blobstore and Python API file. For Python's xmpp API, it is implemented through Ejabberd. Namespace support. Miscellaneous error correction.

Our current design and development Appscale is an open source scalable PAAs (platform-service) cloud computing platform that simulates Google's app (GAE). And we also provide the appropriate software development kits to facilitate the creation of distributed cluster applications based on xen-base clusters, including IAAS (infrastructure as well as services), such as Amazon's aws/ec2 and eucalyptus. Appscale provides a complete framework for researchers to study the application of PAAs and IaaS systems, as well as internal operations. This is true for PAAs (platform-service) cloud technology.

Gae is part of Google's cloud computing, an Internet Application service engine that allows developers to use Gae's API to develop Internet applications, with no bandwidth, no host to worry about, and Google to offer you. At present, free users have 500M storage space, 5 million times per month PV, for the general application should be enough. You can use Gae to host your happy NET, school applications, no longer worry about no host.

The Appscale environment contains four major components. Appscale complements the functionality provided by Google App Engine by building and expanding the SDK from Google App Engine and implementing the open APIs exposed by this SDK. Multiple components within the Appscale automate system deployment, management, scaling, and system fault tolerance to execute app Engine applications.

You can deploy and run the Google app Engine application in Appscale without making changes to your application. Appscale does not mean replacing or competing with Google's App Engine. It is just a framework for cloud infrastructure experimentation and does not stretch upward into Google's proud infrastructure.
