Abstract

On-premise server performance depends on several parameters. Server’s hardware resources, operating system (OS) and runtime environment are persistent during server and service life cycle; they provide constant performance for even server payload. This feature changes if the server migrates in a dynamic multi-tenant cloud. The server’s hardware resources usually are shared among several tenants which impacts server overall performance. In this paper we analyze what runtime environment and OS achieves the best performance for web services in cloud PaaS layer for peak loads, particularly when the increased load happens due to huge number of small messages or by huge message sizes. We propose a middleware strategy to survive the peak loads of huge number of small messages and also a model to transform huge messages into smaller chunks and send to the server as separated sub messages.
