Network virtualization combines hardware and software network resources and network functionality into a single, software based administrative entity. Virtual networks are no longer something to consider in the future.
Versiant’s network virtualization deployment and management deliver the following benefits
- Reduces the number of physical devices needed
- Easily segment networks
- Permits rapid change / scalability and agile deployment
- Security from destruction of physical devices
- Failover mode – defective disk simply switches to a backup on the fly, and the failed component can be repaired, while the system continues to run
Versiant designs Local Area Networks (LANs) are subdivided into virtual networks and VLANs. Doing do will dramatically improve load balancing. You can also improve security by segmenting your network and establishing role and location-based permissions and procedures. Doing this in a virtual environment enables you to be agile and adapt your network architecture as needed to manage changing and increasing network loading and demand.
As businesses adopt the use of SaaS and infrastructure-as-a-service (IaaS) applications in multiple clouds, IT is realizing that the user application experience is poor. That is because WANs designed for a different era are not ready for the unprecedented explosion of WAN traffic that cloud adoption brings. That traffic causes management complexity, application-performance unpredictability, and data vulnerability.
Enabling broadband on the WAN makes the security requirements more acute, creating challenges for IT in balancing user experience, security, and complexity. The traditional WAN architecture was limited to enterprise, branch, and data center. Once an organization adopts cloud-based applications in the form of SaaS and IaaS, its WAN architecture experiences an explosion of traffic accessing applications distributed across the globe.
These changes have multiple implications for IT. Employee productivity may be compromised by SaaS-application performance problems. WAN expenses can rise with inefficient use of dedicated and backup circuits. IT fights a daily, complex battle of connecting multiple types of users with multiple types of devices to multiple cloud environments.
With SD-WAN, Versiant can deliver routing, threat protection, efficient offloading of expensive circuits, and simplification of WAN network management. Business benefits can include the following:
Better application experience
- High availability, with predictable service, for all critical enterprise applications
- Multiple hybrid active-active links for all network scenarios
- Dynamically routed application traffic with application-aware routing, for efficient delivery and improved user experience
- Improved OpEx, replacing expensive Multiprotocol Label Switching (MPLS) services with more economical and flexible broadband (including secure VPN connections)
- Application-aware policies with end-to-end segmentation and real-time access control
- Integrated threat protection enforced at the right place
- Secure traffic across broadband Internet and into the cloud
- Distribute security to the branch and remote endpoints with NGFW, DNS security, and NGAV
Optimized cloud connectivity
- Seamless extension of the WAN to multiple public clouds
- Real-time optimized performance for Microsoft Office 365, Salesforce, and other major SaaS applications
- Optimized workflows for cloud platforms such as Amazon Web Services (AWS) and Microsoft Azure
- A single, centralized, cloud-delivered management dashboard for configuration and management of WAN, cloud, and security
- Template-based, zero-touch provisioning for all locations: branch, campus, and cloud
- Detailed reporting of application and WAN performance for business analytics and bandwidth forcasting
