Abstract: Software developers with service-oriented technologies usually put a lot of efforts to deploy and manage supporting middleware and tools. Meanwhile PaaS in cloud computing aims at providing efficient support for software developers. In the light of this consideration, we have designed and implemented Service4All, a service cloud platform targeting at improving productivity of service-oriented software developers. In this paper, we describe the key technical issues, architecture design and implementation technology of SAE, a key component in Service4All, in terms of scalability. First, we propose a software appliance-based mechanism for elastic middleware management. Second, we describe a micro-kernel-based AppEngine core for efficient coordination of various components. Third, we present a scalable replication framework to achieve highly scalable application services. Finally, through a real application deployed on Service4All, we demonstrate the effectiveness of our solution.
