problems with enterprise wan solutions - the cloud x ecosystem
TRANSCRIPT
What is the problem with current Enterprise WAN solutions?• Customer applications are moving toward
SaaS and PaaS models. As such, hair pinning traffic from branch office to customer data center first, then to cloud causes performance issues.
• Internet has become almost as reliable as dedicated IP (MPLS) networks at a fraction of the cost.
• Customers have less IT staff that understand the complexities of the myriad of branch CPE that is required to secure and optimize the WAN. Any single branch office could have a router, firewall, security appliance, wan acceleration device, caching device, etc. It is too much cost for the customer to manage and maintain all that hardware.
Cisco iWAN solution aims to put an intelligent device on customer premise to leverage multiple connectivity to cloud and internal resources with performance based routing guiding the traffic to the correct path.
What are the demands facing IT departments?
Public Cloud
Private Data Center
Private Cloud
Thanks to Cloud, Customers have gotten used to optimizing cost by hosting applications in different Infrastructure domains
based on Mission Criticality of the Application.
e.g. AmazonHost the test/dev apps, the web2.0
apps. Low security
e.g. Rackspace
Host critical apps that have
performance requirements for
storage and speed but can be virtual.
e.g. Customer Premise
Host apps that must be kept in house
due to regulatory or compliance, or
cannot be virtualized.
User spins up resources on-demand intelligently choosing the best platform for the app.
This is the premise of
Hybrid Cloud
Public IP 3rd party Cloud connectivity
Private IP
In a similar fashion, Hybrid WAN needs to offer customers a way to optimize cost by intelligently choosing options of
infrastructure types that are matched with mission criticality.
e.g. IPSecFor small
office/home office or apps that do not require more than
best effort performance
e.g. MPLScritical apps that
have performance requirements for
latency and delivery
e.g. Cloud X fusion
Fastest path from WAN to SaaS and
PaaS providers
User spins up NETWORK on-demand intelligently choosing the best NETWORK for the app.

disaster recovery
Solutions: SD WAN is Step 1, NFV is Step 2

While Hybrid WAN offers multiple infrastructure options for customers under a single operational model, the ability for the
customer to spin up these resources via a software layer is what makes the Software Defined WAN the next level.
e.g. IPSecFor small
office/home office or apps that do not require more than
best effort performance
e.g. MPLScritical apps that

e.g. Cloud X fusion
Fastest path from WAN to SaaS and

Once there is a single customer portal for control of network services, then we can easily supply the customer with branch office CPE replacement via NFV capabilities.
