WHAT TO CONSIDER WHEN EVALUATING YOUR SD-WAN OPTIONS
PRESENTED BY nterprises currently face
E challenges regarding the price , performance and flexibility of traditional wide area networks ( WANs ). Aggressive growth in the adoption of public cloud services ( 28.6 % year-over-year growth in 2017 ) is forcing organisations to look elsewhere for a more effective network solution to address distributed traffic across remote sites and branch offices . Some of the specific issues organisations face with their traditional WANs include :
• High total cost of ownership ( TCO )
• Lengthy provisioning cycles
• Performance degradation with the growth of cloud traffic
• Inadequate redundancy and resiliency
• Lack of application-aware connectivity
To better manage WAN investments , enterprises are adopting a new approach for their distributed branch office networks . Software-defined WAN ( SD-WAN ) offers improved performance , agility and operational flexibility plus significant cost savings . But not all SD- WAN solutions are created equal .
Traditional WAN performance comes at a premium because it is almost entirely limited to expensive circuits like multiprotocol label switching ( MPLS ). At the same time , the rapid increase of cloud applications being used across distributed organisations has caused a sharp uptick in network bandwidth demands . As these performance needs increase , traditional WAN infrastructures become dramatically more expensive , complex to deploy and difficult to manage . u
