从Google App Engine生态系统迁移

Question

有没有什么工具和/或最佳实践，使得从GAE（Python或PHP）及其服务生态系统（s.a.身份验证、数据存储、搜索、缓存等）迁移到另一种云托管服务，甚至是自托管——的过程相当容易吗？在

It executes automatically over Amazon EC2, Rackspace, Google Compute Engine, Eucalyptus, Openstack, CloudStack, as well as KVM and VirtualBox. It has been developed and is maintained by AppScale Systems, Inc., in Santa Barbara. It supports the Python, Java, Go, and PHP Google App Engine platforms.

AppScale is an open-source cloud computing platform that automatically deploys and scales unmodified Google App Engine applications over popular public and private cloud systems and on-premises clusters. AppScale is modeled on the App Engine API and has support for Python, Go, PHP and Java applications.

The goal of AppScale is to provide developers with a rapid, API-driven development platform that can run applications on any cloud infrastructure. AppScale decouples app logic from its service ecosystem to give developers and cloud administrators unprecedented control over app deployment, data storage, resource use, backup and migration.
