Preparation for cloud migration
While many benefits are gained by migrating to 
geographically dispersed data centers, challenges 
are encountered when a distributed infrastructure is 
deployed. Load balancing traffic to remote data centers 
can add latency because of the round trip to remote data 
centers, leading the IT department to want to increase 
the local computing resources before distributing the 
workload to remote data centers.
Increasing the local compute resources introduces 
the need for virtual machine intelligence. Otherwise, 
services cannot be delivered with optimal response 
times, resulting in suboptimal use of the distributed 
infrastructure. Cisco ACE dynamic workload scaling 
addresses these challenges:
• 
Virtual machine visibility: Integration with VMware 
vCenter enables ACE to actively monitor the current 
resource utilization of the local virtual machines to 
make an intelligent decision regarding whether to 
distribute workload locally or send it to the remote 
data center. 
• 
Service latency: Cisco ACE enables customers to 
efficiently use the local compute resources before 
distributing workload to a remote data center.   When 
the compute resources of the local virtual machines 
are fully used, ACE distributes the workload to a 
remote data center to service the increased load.
• 
Limited scalability: Integration with OTV provides 
increased capacity to scale an application across 
geographically dispersed data centers without 
compromising the autonomy of the data centers 
or the stability of the overall network.  ACE dynami-
cally adds remote compute resources to service 
increased workload when local resources become 
scarce.
• 
Complex deployments: Integration with Nexus 
7000 and VMware vCenter enable ACE to service 
increased workload faster and simpler while pre-
serving existing network design.  As a result, busi-
nesses gain increased application resiliency while 
keep operating expenses low.
Business Reasons for Deploying Cisco ACE 
Dynamical Workload Scaling
• 
Increased application resiliency: DWS enables 
effective disaster-recovery mechanisms that 
increase availability of the applications through 
flexible workload mobility.
• 
Flexibility: DWS extends ACE intelligence to achieve 
greater virtual data center resilience, performance, 
and flexibility.
• 
Greater scalability: As data centers evolve from a 
hierarchical architectural model to a flatter Layer 2–
based distributed model, DWS enables businesses 
to scale applications and the infrastructure without 
increasing the costs and resources needed for 
administration and management.
• 
Optimal hardware resource utilization: By distribut-
ing workload to a remote data center only when local 
compute resources have been fully utilized, Cisco 
ACE offers significant cost saving benefits and 
operational benefits.
