SD-WAN reduces line costs and improves transmission quality
The times are different. As companies adopt SaaS/IaaS applications in a cloudy environment, IT staff are increasingly aware that users' application experiences are poor. This is because the cloud brings unprecedented WAN traffic, and the WANs designed for different generations are not ready. The huge traffic volume leads to complicated management operations, unstable application performance, and security holes in the data.
Enterprises facing the cloudy world are more exposed to major security threats and regulatory compliance issues. Employees, partners, contractors, vendors, and visitors should have different access to applications, and protecting important assets of the enterprise is a daunting task. When WAN is enabled, security requirements are more urgent, creating a daunting challenge for IT staff to balance the user experience, security, and complexity.
Traditional WAN features connect users in branch offices or campuses to applications hosted on the data center server. MPLS dedicated circuits are typically used to ensure a secure and stable connection. But in a cloud-centric environment, this approach is no longer applicable.
