An SD-WAN platform allows organizations to easily integrate private clouds, SaaS, and IaaS applications.

Multi-cloud connectivity simplified with SD-WAN

  • Client experience is ensured through SaaS optimization. 

During this time the application is hosted in the corporate data center. Routing all application traffic from the branch to the data center makes sense. Cloud to a datacenter just increases latency and influences application performance. 

Understanding this, enterprises can decrease that latency by searching for the most advanced and best edge-based SD-WAN platform. It should offer SaaS optimization provisions to consistently and safely connect clients from branch sites to SaaS applications. Simultaneously check the Quality of the SaaS (QoE) experience.

The main functionality SD-WAN purchasers should search for is recognizing the primary packet. Applications are recognized and categorized in the main packet. This allows traffic to be progressively routed to the ideal destination. (Regardless of whether it is a data center cloud service provider  or cloud security), which decreases latency and guarantees compliance with security policies. 

Also, the Microsoft Office 365 API integration considers secure Internet segregation to the closest Office 365 access point. So it ensures the best Office 365 performance is accessible.

  • Smart local output for the internet

Apps from different classes require various types of consent for security policies and controls. Starting packet detection plays an important role here, but there are other functions on leading SD-WAN platforms that can further improve security without affecting application performance. 

Various applications can be planned for virtual WAN layers, each supporting different QoS, transport, and failover features. As an example, trusted business SaaS, like Office 365, can be routed via the internet to an overlay that connects directly to the closest SaaS instance, while untrusted or unknown traffic is routed to the hub-based firewall for closer inspection. 

In terms of firewalls, a zone-based, centralized stateful firewall is fundamental to guaranteeing secure, total internet blackouts at the local edge of the network. It is possible from a branch office to connect directly to trusted SaaS applications and IaaS and, in addition to this, it blocks any traffic from the LAN trying to gain access to the branch network.

  • Cloud automation and SD-WAN integration simplify networks

Complexity isn’t the enemy when it comes to network management, and this is especially true for large, worldwide systems, including AWS Virtual Private Clouds or Microsoft Virtual Networks (VNets). Nevertheless, such large networks can be administered with ease through an SD-WAN platform based on the edge.

Direct connections to worldwide backbone networks help to reduce the complexity of the SD-WAN solution, along with the reduction of connections to points, and the connection of branch locations to direct province points (POPs). Furthermore, SD-WAN overlays should support branch communications in each VPC without virtual gateways.

  • A case of SASE has occurred 

As a result of SASE, SD-WAN has been profoundly affected. As SD-WAN changes an infrastructure with consistent availability and smoothes out work processes, SASE takes the next logical step by deploying security controls into the cloud closer to the end-users where the data is generated (at the network boundary) and therefore most vulnerable. 

SASE is not a technology in itself, but as an architectural system, it allows companies to integrate security and networking into a single model of cloud services. 

In 2021, SD-WAN will become the foundation for SASE: a cloud-compliant programmable network platform for integrating network parts with security segments, SASE components, and unified management. 

The best SD-WAN solutions should integrate external cloud security services provided by the best cloud security organizations. SD-WAN platforms that integrate advanced APIs provide network administrators with opportunities to implement ordinary automation of network-wide security policies.

In this way, they can take advantage of the advantages of the high-level local WAN edge Zero Trust, as well as participate in the adaptability and opportunity of the decision to take advantage of cloud-based security services from their number one security provider.
