Organisations are adopting an ever expanding number of SaaS applications hosted in multiple public clouds. The widespread adoption of Office 365, AWS, Azure, Salesforce etc. means that the demand for bandwidth has never been higher than it is today and this upward trend is only set to continue. Traditionally, organisations have utilised MPLS circuits to connect users at branch and head offices to applications hosted in the data centre securely and reliably.
As businesses race to adopt the use of applications in the cloud, traditional network infrastructures deliver a user experience which is increasingly poor. WAN networks designed for a different era, are not ready for the unprecedented surge in traffic that cloud adoption brings.
Opening the enterprise to the cloud also exposes major threat and compliance issues. It is extremely challenging to protect the critical assets when applications are widely spread and accessed by a diverse range of users, from employees to partners, contractors, vendors, and guests. Utilising low cost broadband can make security requirements more acute, creating challenges for network administrators in balancing the user experience with required levels of security
SD-WAN is designed to address these challenges. Software-defined WAN lowers operational costs and improves resource usage for multi-site deployments. Network administrators can use bandwidth more efficiently and can help ensure the highest level of performance for critical applications without sacrificing security or data privacy.
What Are the Benefits of SD-WAN?
A cloud-delivered WAN architecture, SD-WAN, makes it easier to securely move data around physical and virtual locations.
WAN optimisation delivers optimal cloud application performance from multiple clouds to users anywhere, improving the user experience. In the event of link failure or link degradation, application-aware routing can dynamically route traffic between dedicated circuits and secure Internet connections to drive constant delivery of business-critical applications. Additionally, organisations can save money by replacing their expensive MPLS services with more economical and flexible broadband.
SD-WAN architecture features distributed security at the branch level. Data does not have to travel back to the headquarters or data center for advanced security protection (firewall, DNS enforcement and intrusion prevention).
