What is Software-Defined WAN?
Software-Defined WAN Features & Capabilities:
- WAN Optimization
- Multi-Cloud Management
- Centralized Orchestration
- Zero-Touch Provisioning
- Virtual Private Network (VPN)
- WAN Optimization
- Application Delivery Control
This worked for a time because all information was stored in the data center, but now most applications are hosted in the cloud, and sometimes multiple clouds. Backhauling this information through traditional WAN can cause performance issues and delays often referred to as latency. Latency issues are a main reason many companies are exploring SD-WAN.
WAN Optimization
Businesses should perform WAN optimization as part of an SD-WAN upgrade, especially if they are dealing with latency issues. Even with traditional WAN, optimization can increase app speeds using several methods:
Deduplication - deleting redundant or repeat information
Caching - storing information for faster access
Compression - shrinking files by removing non-essential information
By optimizing the WAN beforehand, companies can make the most of their SD-WAN upgrade.
Multicloud and Hybrid Cloud Management
SD-WAN products improve connectivity and boost security in the multicloud by centralizing cloud management, making it easier. The right products can encrypt data across security points while providing firewalls and app-based security. SD-WAN can also use virtual private networks (VPNs to improve security).
