Three points when introducing SD-WAN
With the Korona-ka, an increasing number of companies are introducing cloud services such as video conferencing and groupware and making remote work permanent. Along with this, congestion on Internet lines and closed networks has become a problem. Another issue is the increase in operational load due to the response.
SD-WAN is the solution. However, there may be many network administrators who seem to have high introduction hurdles such as the characteristics of each base and security assurance.

What is SD-WAN?
SD-WAN is an abbreviation for Software Defined Wide Area Network, which is a service that dynamically manages and operates a WAN (wide area network) by software control. As the use of public clouds expands due to the shift to cloud computing for business applications and the business environment changes drastically, there is an increasing need for a technology that can flexibly control the WAN so that employees can work comfortably.
One of the reasons is the local breakout .
Local breakout refers to a network configuration that allows traffic to specific business applications and services on the cloud to flow directly from the base to the Internet, not via a gateway built in a data center or the like. By locally breaking out cloud services such as groupware frequently used by many employees and high-traffic web conferencing, it is possible to distribute traffic and eliminate congestion .
Another reason is management and setting by remote control .
Since SD-WAN can be remotely set and monitored from the management screen of the Web, it can be installed and monitored without the administrator having to go to the installation base.
Points to keep in mind when introducing SD-WAN
The following should be considered when considering the introduction of SD-WAN.
SD-WAN: Flexibility
If there are multiple bases, it is ideal to install SD-WAN only at the required bases in consideration of the scale of the bases and the existing network environment. Therefore, make sure that you can build a network even if SD-WAN installation bases and routerless or non-SD-WAN router bases coexist .
SD-WAN: Security
While SD-WAN improves traffic performance when the site is directly connected to the Internet, security tends to be vulnerable. It's also a good idea to check in advance that your SD-WAN router has security features such as web filtering, sandboxing, firewalls, and antivirus . It can also be used in combination with Web security services and endpoint security for even stronger security.
SD-WAN: Operation
Introducing SD-WAN tends to require more equipment and services, such as closed networks and security, as well as cloud services such as SaaS and IaaS, as well as routers and lines. Introducing them from different vendors will complicate daily management, monitoring, and response in the event of a failure, leading to an increase in the burden on the administrator. It is more efficient to centralize these windows .
Building a network infrastructure that can respond to increasing use of cloud services
According to MM Research Institute, the compound annual growth rate (CAGR) of the entire cloud market is expected to be 14.5% by 2025, and the public cloud is expected to grow significantly.
This movement may be influenced by "hybrid work," which is attracting attention as an after-corona work style.
It is expected that the issue of network congestion will become more apparent in the future, so we recommend that you consider introducing SD-WAN before that happens.
