Query: Improved Cloud resource allocation: how INDIGO-DataCloud is overcoming
  the current limitations in Cloud schedulers   Performing efficient resource provisioning is a fundamental aspect for any
resource provider. Local Resource Management Systems (LRMS) have been used in
data centers for decades in order to obtain the best usage of the resources,
providing their fair usage and partitioning for the users. In contrast, current
cloud schedulers are normally based on the immediate allocation of resources on
a first-come, first-served basis, meaning that a request will fail if there are
no resources (e.g. OpenStack) or it will be trivially queued ordered by entry
time (e.g. OpenNebula). Moreover, these scheduling strategies are based on a
static partitioning of the resources, meaning that existing quotas cannot be
exceeded, even if there are idle resources allocated to other projects. This is
a consequence of the fact that cloud instances are not associated with a
maximum execution time and leads to a situation where the resources are
under-utilized. These facts have been identified by the INDIGO-DataCloud
project as being too simplistic for accommodating scientific workloads in an
efficient way, leading to an underutilization of the resources, a non desirable
situation in scientific data centers. In this work, we will present the work
done in the scheduling area during the first year of the INDIGO project and the
foreseen evolutions.
