There are a lot of options when it comes to SD-WAN technology, but which one is the best? In this post, we’ll take a look at some of the most popular SD-WAN examples and explore their features. We’ll also discuss why each option might be a good fit for your business. Let’s get started!
What is SD-WAN?
SD-WAN is an acronym for Software-Defined Wide Area Network. It is an approach to WAN network that uses software-based network appliances to replace existing hardware-based network appliances. Also, this solution allows enterprises to communicate with each other via broadband connections.
SD-WAN is the best solution for organizations that need the advantages of cloud computing. But still want their dedicated private network.
What Is SD-WAN And How Does It Work?
SD-WAN works by connecting branch offices, data centers, and other places over broadband connections. This can be a DSL connection or a T1 line. The advantage of this type of connection is that it is flexible and easy to scale.
This means that if the company grows, you don’t need to spend extra money on new hardware. Because you can simply add more bandwidth. SD-WAN has three main components:
SD-WAN Controller
This is the appliance that manages all the other components in the network and monitors and controls them for performance management and security management.
SD-WAN Router
This is the router that connects the local offices, branches, or other remote sites over a broadband connection.
SD-WAN Appliance
This is another name for a software-based router or firewall that connects remote sites over a broadband connection.
Why Use A Software-Defined Network?
The main benefit of using a Software Defined Network is cost savings due to the low capital expenditure (CAPEX) required. Also, the low operational expenditure (OPEX) involved in the maintenance and support of software-defined networks. This is when compared to traditional hardware-based networks where there are high CAPEX costs involved in replacing the hardware.
This is when it goes out of date or requires maintenance and support from an external service provider. Something which is not needed with software-based networks since they run on standard commercial off-the-shelf (COTS) equipment. Also, most if not all service providers offer free 24×7 support for their products.
SD-WAN Benefits
The benefit of SD-WAN is that it allows individual sites to communicate with each other. This is over a secure encrypted link in a flexible manner. It means that if you have offices in different locations or even different countries you have more control.
That is over how they communicate with each other and who has access to them. Also, you can have more control over security requirements in these communications. Something that is not available in traditional VPN technology when used as a WAN link solution.
The other benefit of SD-WAN is that it is a more scalable and flexible solution as compared to traditional WAN technologies. Software-Defined WANs have several benefits that are seen in the long run.
SDN technologies are much less expensive than traditional networks. There are no physical components to install on-site, so there’s no need for expensive installation costs or costly support contracts. The applications you deploy over an SDN can also be managed and maintained by a single team in one location, saving you money on travel expenses and management time.
