Whether your strategy is hybrid, multi-cloud, or all cloud, success always depends on one thing — the ability of your network to keep pace with your digital transformation. Even if your network is performing well, changing where and how apps, desktops, and data are stored and delivered will fundamentally reshape the volume and paths of traffic through your WAN. But when you transform your network with SD-WAN, you can reinvent what’s possible — delivering operational agility and enhanced security at a reasonable cost.
Why networks become obstructions on today’s cloud journey
In traditional network architectures, organizations backhaul traffic from remote and branch locations through the data center because that’s where internet connectivity and the firewall are. But that’s problematic for two reasons:
- Cost – It’s expensive and inefficient to backhaul traffic to the data center rather than going straight from each branch location out to the internet or SaaS.
- Performance – The data center detour also adds latency, slowing business apps and data. This is especially damaging because digital workspace performance is the cornerstone of productivity in the modern workplace.
The network must be transformed to meet the demands of the cloud
IT leaders believe their organization’s ability to migrate apps to the cloud is hampered by the increased complexity of their network infrastructure.
Easing the journey to the cloud
Today’s organizations are increasingly motivated to reassess their current network infrastructure. According to IDC, some 79 percent of worldwide enterprises plan to address disruption through a hybrid cloud strategy — one that extends from on-premises data center(s) out to the public cloud and across the WAN to your branch offices and remote sites. And a trusted SD-WAN provider is key to a solution that works in concert with your cloud initiatives.
4 ways SD-WAN readies your network for every phase of the cloud journey:
- Supporting SaaS apps and internet use
- Migrating apps to the cloud
- Creating a hybrid, multi-cloud environment
- Making the internet available to customers
SD-WAN, SaaS apps and internet
If your cloud strategy currently includes providing access to the internet along with SaaS apps, SD-WAN can help you maintain security while ensuring a high-quality experience for users in any location. By bringing new flexibility and control to the modern enterprise network, SD-WAN makes it easy to securely connect your branches directly.
As a result, you no longer have to backhaul remote and branch site traffic, potentially over long distances, to the central data center. Instead, you can maintain cost-effective, secure connections directly to the internet and SaaS applications from every location in your organization.
SD-WAN automatically recognizes internet sites and individual SaaS applications with deep packet inspection, that allows you to define policies for how individual applications or families of applications are handled. You can choose what application traffic should immediately break out of the branch to the internet or SaaS and which should be sent back to the data center. You even select which applications are blocked or logged for all users or a subset of users.
SD-WAN and migrating apps to the cloud
Solving for latency
As you begin moving business apps from your data center to the cloud, SD-WAN ensures LANlike performance for every app. Cloud application traffic can be uploaded directly from branch and remote locations to the cloud without being routed through the data center, reducing latency.
Boosting user productivity
Intelligent path selection ensures a high-quality user experience for applications by detecting the apps using the WAN and actively managing traffic for those applications across the logical connection. The solution optimizes the performance of applications such as Unified Communications while controlling costs by reducing the amount of data that crosses the WAN and allowing the use of high-bandwidth broadband connections as enterprise-class WAN connections.
As with SaaS and web apps, SD-WAN can apply app-specific security policies to provide the right level of protection for each app without overly restricting the user experience. For IT, simplified WAN management combined with deep visibility into app and network performance makes for a smoother, more successful move to the cloud.
Creating a hybrid, multi-cloud environment through strategic partnerships
If you’re pursuing this type of hybrid strategy, SD-WAN makes it simpler to support multiple cloud topologies. And so does having strategic partnerships with an interconnection data center company.
That will allow you to use SD-WAN to take advantage of its hybrid interconnection model for providing high-speed, low-latency connectivity between multiple cloud providers and enterprise networks. This combination enables companies like yours to support a variety of application delivery strategies and select technologies based on what works best for you now and in the future.
Only 24% of organizations believe their networks satisfy their hybrid-cloud app delivery.
Extending the internet to customers
Internet access is an integral and expected part of today’s enterprises. For example, consumers are increasingly blending online and in-store retail experiences to enhance the way they shop for, buy, and receive products. So in response, many retailers are offering guest Wi-Fi access for customer-facing apps and the open internet over their own in-store networks. Similarly, internet access for both business and personal use is available in healthcare clinics, branch offices, hospitality locations, and outdoor venues.
