What Does Cisco ACE Dynamic Workload
Scaling Do??
Scaling Do??
Virtualization technology is gaining momentum in
enterprise data centers; Enterprises are adopting this
technology to increase compute resource utilization
and obtain cost savings and operational benefits. In
virtualized environments, virtual machines can move
anywhere in geographically distributed data centers
to provide added application resiliency and flexible
workload mobility.

virtualized environments, virtual machines can move

to provide added application resiliency and flexible
workload mobility.
To enable all the benefits of distributed environments,
Local Area Networks (LAN) must extend across diverse
locations. Cisco OTV provides an optimized solution
for Layer 2 connectivity extension across any transport.

Cisco ACE integrates with Cisco Nexus 7000 and
VMware vCenter to deliver intelligent load-balancing in
distributed data centers. Cisco ACE queries Cisco Nexus
7000 to obtain the virtual machine locality information
and actively monitors the CPU and memory utilization
of the local virtual machines to determine when local
resources are scarce.

and actively monitors the CPU and memory utilization
of the local virtual machines to determine when local
resources are scarce.
With virtual machine locality and resource utilization
information, Cisco ACE is now able to make dynamic
load-balancing decisions based on user configurations.
During normal operations when local resources are suf-
ficient, ACE load-balances the incoming traffic to only the
local virtual machines. When local resources become
scarce due to increased workload, ACE dynamically
adds more compute resources to service the increased
load by leveraging OTV to direct traffic to additional
servers in a remote data center.

Dynamic Workload Scaling
Dynamic Workload Scaling
Data centers are evolving from a hierarchical archi-
tectural model to a flatter geographically distributed
model that uses Layer 2 LAN extension technology to
increase the availability of application services while
optimizing compute resource capacity. One of the main
factors accelerating these changes is the rapid adoption
of server virtualization technology in data centers. In
virtualized data center environments, virtual machines
can move anywhere in the geographically dispersed
data centers to provide higher application scalability.
Customers gain the following benefits when transitioning
to a distributed infrastructure:
