1 Web Traffic Offload of MPLS Networks Jeff Bird, RSMZscaler
2 Top multinational enterprise network & telecoms priorities “Which of the following initiatives are likely to be your firm's top telecom adoption priorities over the next 12 months?”2013 GEN5:Base: 954 Telecoms decision-makers at firms with 1,000 or more employees who are responsible for multicountry or global network and telecoms technology decisions (“critical priority” and “high priority” responses); Source: Forrsights Networks And Telecommunications Survey, Q1 2013
3 Business globalization drives need for a highly available and reliable international site-to-site networkWorkforces are both increasingly distributed, and mobile.Globalizing business operations demands a highly reliable and resilient corporate network.Globalization resets business, customer and employee expectations about speed of responsiveness and decisions, and for team collaboration.The more internationally distributed a firm’s operations, the bigger the challenge to deliver consistent apps performance.Security becomes a big issue around Web Apps
4 MPLS interest is driven mostly by perceptions of “value for spend” Reasons for using MPLS - rankedNeed more QoS network capacityNeed high network reliability, and predictabilityWant to improve user experience with collaboration and productivity appsNeed to upgrade network to support new enterprise communications appsWant a simplified WAN infrastructureWant to improve access to internally hosted, and off-premises hosted and cloud applicationsWant data traffic routing control including QoSNeed a modern and future-proof networkNeed to integrate disparate networks globally
5 The Age of Mobility (it’s about the Web apps!) Customer and employee expectations of more , easy to use, mobile apps will change how business is doneDriversIT ChallengesWorkplace virtualizationCollaboration (internal, external)Consumerization (bring-your-own devices, apps)Manage growing complexity (endpoint, network, information security)Cost management – licenses, IT supportDirect technology purchases (BYO-T) risk bypass of IT standards
6 Virtualization success rides on getting your Cloud strategy right Most firms are keen to consolidate data centersA majority will adopt hybrid cloud – own DC + virtual private cloud &/or public cloud (e.g., Office 365, Salesforce, Dropbox, gMail)Many will migrate UC&C app to SaaS modelsAll virtualizing firms are beefing up network securityMost firms will shift network and security management towards 3rd party services to help move forward faster and better …Common thread here is more Web traffic…

Now it’s just the opposite.” – CIO, Fortune 50 company“
