1. [Challenges of Company A] With existing WAN, it takes time to add bases! There is a security problem ...
Company A, a daily miscellaneous goods manufacturer with global and multi-store development. Every time A opens a new store in the world, it has been necessary to make individual settings for network devices. It took a lot of time to set up and check these devices, and the existing network was inflexible, making it difficult to quickly open stores in line with business needs.
In addition, each store had to build not only a network for using in-house systems and a network for handling credit card information, but also a network with different security requirements, such as a kiosk terminal and IP phone, on the same WAN. However, it can be quite costly to sign up for a carrier VPN service separately for each network. We also considered the realization of VLAN and VRF (Virtual Routing and Forwarding) settings without subscribing to multiple VPN services, but we had to give up because the settings were complicated and not scalable. did.
2. [Challenges for Company B] Existing WANs becoming more complex, line costs continue to rise ...
Manufacturing company B, which has many new bases and the consolidation of bases due to acquisitions.
Company B was building a WAN using MPLS lines. However, although the MPLS line used by Company B was expensive, its bandwidth was low and the speed was low, so it was not cost effective. A backup line was also contracted for line redundancy, but it could not be used effectively with the existing network configuration, and the backup line was actually dormant. However, it was necessary to pay a high maintenance cost for such a line that was not always used.
In addition, the use of cloud services has become increasingly active within the company for data exchange with applications and customers. However, with existing network configurations, traffic routes could not be changed according to the application. Since all traffic destined for the Internet also flows over MPLS lines, we have squeezed even less bandwidth. As the traffic increased, it was necessary to increase the line bandwidth and expand the IT equipment in the data center as a hub, and the cost of maintaining the existing network was increasing.
3. [Solutions of both companies] "Four points" that we focused on when moving from the conventional WAN environment to SD-WAN
Both companies determined that it would be difficult to maintain and enhance their existing WAN environment. The system managers of both companies adopted SD-WAN as a result, but let's organize the points of attention why they chose it.
