Considering SD-WAN Purchase? Questions to Ask the Vendor

SD-WAN: Questions to Ask Vendors (and Yourself)

In addition to WAN streamlining, SD-WANs now includes a range of features including application-aware firewalls, advanced WAN optimization, and routing functionality, all managed by one unified management software.

A branch office, retail store, restaurant, or production facility can run SD-WAN software on a server to replace multiple, actual devices with a single, virtual device, or take advantage of a cloud service that is managed by SD-WAN.

In recent years, SD-WAN adoption has become more complicated for companies that wish to take advantage of its new capabilities since it integrates security, networking, application performance, and cloud services.

It will help SD-WAN buyers explore critical decision-making points as well as provide questions to ask potential vendors or service providers.

What do you need to know about SD-WAN Solution?

Companies must consider the following scenarios before switching to SD-WAN. These are some of the typical questions that leaders should ask:

• What are the most common applications used on the web?
• When there is a system crash, which of the applications will have priority?
• Can these applications deliver the performance clients expect?

Self-managed SD-WAN or managed SD-WAN service?

Because of its complexity, SD-WAN can be challenging to implement. To implement an SD-WAN, an enterprise must do a great deal of work. WAN planning involves analyzing historical traffic patterns, estimating current and future bandwidth requirements for each site, and developing policies for each type of traffic. Start with voice, video, and data traffic, then drill into specific applications.

Every location should have two WANs to allow for both optimization and failure. Additionally to upgrading software and troubleshooting, you must create reports and undertake other tasks.

There are few questions prospective SD-WAN vendors should ask themselves are –

• How many tutorials, training materials, and configuration guides are available?
• Can the vendor offer guidance on how to determine the appropriate bandwidth level and system requirements for each site?
• What is the purpose of a product guide, and how often are software updates provided?
• At present, how much does it cost to renew a license?
• Are there any charges for the support I can expect, and what level of support can I expect?

You have many other options to consider if you are not able to hire skilled workers or have the CAPEX for a DIY project:

• Third-party SD-WAN applications can be configured, tested, and set up with your settings. It is in this case that you will make the initial buying decision in terms of which features and functions are appropriate for your business. Link purchases are made over WANs. Clients are better positioned to gain rapid progress because they already know about the hardware. How does the adder disappear when you switch on the band? Can you deal with consistently updating software, maintaining systems, and changing operating needs?
• A co-hosted SD-WAN service event may include working with an SD-WAN vendor or a service provider that is providing the stream, network, or connection. They can assist with planning SD-WAN deployments. Most delivery, processing, and support issues related to service levels are the responsibility of the service provider. The sales department always makes the final decision and maintains some level of control over the process. To clarify the obligations that do not become unclear, the two parties need to ask: how can they best clarify the parts of the agreement?
• In a completely managed SD-WAN, IT personnel contract a third party who has the required technology, resources, and, as a general rule, its network. The process of picking specific features may very well be as simple as perusing a catalog. The defects prevent you from changing clients and restrict you when choosing.

Service providers should be asked the following questions:

• What SD-WAN network are you using?
• If there is an argument about whether the service is down or blacked out because of the network or SD-WAN, how would you try to avoid pointing fingers?
• What is the number of points on your face and how great is your site with my remote locations?
• Can you tell me how visible the site is?
• Is there any kind of notification, alarm, or notice I get from your system?
• What types of SLAs are available?
