dynamic and ever-changing natures of Internet require the just-in-time scalability of middleware for Internetware.As the middleware for Internetware becomes much more powerful and complicated than ever
it is challenging to autoscale middleware dynamically and efficiently under the Internetware environment.In this paper
a profile-based approach is proposed to automate the dynamic scaling of Internetware middleware.Profiles formalize (a) states that are keys to consistent middleware being scaled;(b) reflected information required to trigger and fulfill dynamic scaling;and (c) the best-practice of scaling domain-specific middleware.The autoscaling tool based on this approach is capable of provisioning a scalable middleware and scale it dynamically according to the needs of Internetware.The provisioning and dynamic scaling of a scalable Mongrel cluster exemplifies the feasibility and efficiency of this approach.
