document: Autonomous resource provisioning for multi-service web applications Dynamic resource provisioning aims at maintaining the end-to-end response time of a web application within a pre-defined SLA . Although the topic has been well studied for monolithic applications , provisioning resources for applications composed of multiple services remains a challenge . When the SLA is violated , one must decide which service ( s ) should be reprovisioned for optimal effect . We propose to assign an SLA only to the front-end service . Other services are not given any particular response time objectives . Services are autonomously responsible for their own provisioning operations and collaboratively negotiate performance objectives with each other to decide the provisioning service ( s ) . We demonstrate through extensive experiments that our system can add\/remove\/shift both servers and caches within an entire multi-service application under varying workloads to meet the SLA target and improve resource utilization .
