What might 2018 hold for SD-WAN providers and customers? Let's take a look.
How Can You Best Connect Your SD-WAN to the Cloud?
Before rideshare services like Lyft and Uber became popular, getting a ride in a stranger's vehicle was an ad hoc process – you had to be either close enough to flag one down or have the number of a local taxi provider. Plus, payment preferences and acceptable tipping thresholds often varied considerably between drivers. In contrast, ridesharing is highly centralized and automated; instead of interacting with individual cabs, customers are interfacing with the platform itself, which determines who picks them up, processes all payments and enables precise tipping based in part on a two-way rating system.
A similar divide separates traditional WANs from SD-WANs, with the latter providing the centralization, automation and overall scale the former can't match. However, connecting an SD-WAN to the cloud can still sometimes spark the same anxieties associated with managing legacy WANs (or getting a cab in time), namely the feeling that every service, device or vendor is different and as such prone to its own particular set of risks. There are many possible complications, including:
- Having to deploy additional security appliances on customers' premises for secure connectivity.
- Dealing with the best-effort limitations of Internet links and/or the high cost and operational complexity of MPLS circuits.
- Ensuring branch office users are subscribers to an MPLS VPN service as part of private cloud connections to IaaS or SaaS.
- Negotiating these direct connections, a costly process that can take months to complete.
- Navigating broader issues with IaaS/SaaS, such as their unpredictable response times and the dangers of accessing them via public Internet.
The ultimate challenge is to ensure predictable, secure performance regardless of the underlying mode of transport. The good news is that SD-WAN providers like Talari, through technologies as well as partnerships, are uniquely equipped to deliver this ideal combination.
Granular and Secure Internet Breakouts: The Difference-makers for Cloud Connectivity
Implementing an SD-WAN edge solution is the crucial first step to overcoming many of the connectivity challenges we outlined earlier. For example, it can combine commodity Internet with MPLS while offering a controller-based architecture to centrally manage all its nodes. Local Internet breakouts also address Quality of Experience (QoE) expectations not usually met by traditional WAN architectures.
Beyond these benefits, the SD-WAN cloud can be extended to encompass key cloud services provided by Zscaler and Palo Alto Networks. The integration of Zscaler into the Talari SD-WAN solution enables access and security policies to be defined and enforced across the entire WAN from one console. As a result, it helps reduce bandwidth costs, accelerate the user experience and simplify security infrastructure. SD-WAN nodes at every branch site can benefit from cloud Zscaler or Palo Alto connectors for traffic forwarding, meaning there is no need to backhaul through the data center or set up security appliances at each location.
With granular and secure Internet breakouts, it's possible to efficiently scale your SD-WAN as your connections to cloud services proliferate. WAN-cloud connectivity must be dependable, and an SD-WAN platform from Talari Networks ensures that they are. Learn more by requesting a demo today or clicking the banner below.
