In today’s datacenters, resource requests from tenants are increasingly transforming into hybrid requests that may simultaneously demand IaaS, PaaS, and SaaS resources. This paper tackles the challenge of modeling and deploying hybrid tenant requests in datacenters, for which we coin “networklet” to represent a set of VMs that collaboratively provide a PaaS or SaaS service. Through extracting networklets from tenant requests and thus sharing them between tenants, we can achieve a win-win situation for datacenter providers and tenants.
