With the development of globalization, more and more enterprises start to develop overseas markets to the world. In the process of developing overseas business, they will encounter some pain points, such as: how to achieve the interconnection between enterprise branches? How to achieve interconnection between branches and data centers? In this context, SDWAN and VPN become the main choice for enterprises to make remote network connection.
SDWAN and VPN have different uses and advantages in the scenario of enterprise going abroad. In this paper, we will analyze the following aspects:
1.Functions and Uses
SDWAN is a WAN technology that manages multiple Internet connections and provides better bandwidth utilization and network reliability. the main advantage of SDWAN is that it enables rapid deployment, network optimization and cost reduction. Enterprises can use SDWAN to manage overseas branch offices and data centers, ensuring reliable network connectivity and high quality network performance.
VPN is a technology used to securely connect remote networks. VPN ensures data security and confidentiality by transmitting packets from the public Internet through encryption and tunneling technology. the main advantage of VPN is that it enables telecommuting and connecting remote branch offices. Through VPN, employees can connect to the corporate intranet from anywhere and access internal resources and data.
2.Security
In the process of enterprise going abroad, data security is an important consideration. sdWAN and VPN have different advantages in data security. sdWAN can protect data from theft and tampering through encryption technology and traffic isolation function. In addition, SDWAN enables network security management to identify and block malicious traffic, providing better security and reliability.
VPN protects data security through encryption and tunneling technology to ensure that data is not stolen and tampered with during transmission. VPN also enables authentication and access control to prevent unauthorized users from accessing the internal corporate network.
3.Network performance
In the process of enterprise going abroad, network performance is crucial to the operation and efficiency of enterprises. SDWAN and VPN have different advantages in terms of network performance. SDWAN can utilize multiple Internet connections, achieve bandwidth load balancing and network optimization, and improve network performance and reliability. In addition, SDWAN enables traffic classification and QoS (quality of service) to ensure network performance and user experience.
VPNs ensure data reliability and integrity by tunneling packets away from the public Internet. VPNs also enable QoS and traffic control to ensure network performance and user experience. However, the network performance of VPN is limited by the Internet connection, so VPN may not perform as well as SDWAN in terms of network performance.
4.Deployment and Management
Deploying and managing network devices is a tedious task in the process of enterprise going abroad. SDWAN and VPN have different advantages in deployment and management. SDWAN can achieve rapid deployment and automated management. SDWAN can automatically discover and configure network devices, which reduces the cost and workload of deployment and management. In addition, SDWAN allows centralized management and monitoring of network devices, improving network reliability and security.
VPN also enables rapid deployment and centralized management. VPN can be centrally managed and monitored through VPN hubs, reducing the cost and effort of deployment and management. However, VPN deployment and management requires certain technical knowledge and experience, which may be difficult for some SMEs.
SDWAN and VPN have different uses and advantages in the scenario of enterprise going abroad. Enterprises can choose the right network technology according to their needs and actual situation. If enterprises need to manage overseas branches and data centers, and need to achieve optimization and network reliability for multiple Internet connections, then SDWAN is recommended.
If an enterprise needs to telecommute and connect remote branch offices and needs to ensure data security and confidentiality, then VPN is a good choice. However, for large enterprises with multiple locations, VPNs can often cause problems with voice and video applications due to high latency or congestion on the network.
