IT infrastructures are becoming more complex to handle by the day. Data Centers (DCs) are now burdened with high-speed loads with Cloud applications on the rise. Accordingly, there is a rising need for DCs to become more reliable and secure, embracing the powers of low latency, interconnectivity and bandwidth.
This change in landscape has made the need for Software Defined Wide Area Networks (SD-WANs) quite pronounced. In terms of numbers, the global SD-WAN market stood at USD 1.9 billion in 2020 and is estimated to reach USD 8.4 billion by 2025 at a CAGR of 34.5%.
Primarily deployed in large network setups, SD-WAN leverages web-oriented tunnels, firewall software, and virtual technologies with the end purpose of connecting remote endpoints.
But what exactly is SD-WAN?
Getting Acquainted With SD-WAN
SD-WAN, a virtual wide area network relies on software technologies, including internet-oriented communication tunnels, software-ridden network encryption, firewall software and others. It is ideal for operating mid- to large-scale computer networks spread across disparate locations.
What the SD-WAN does is it simplifies the network complexities. This includes configuration, management and optimisation aligned with WAN networks. It renders robust branch connectivity by dissociating the network hardware from the control mechanism, streamlining the WAN’s operation and management.
Seamless Connectivity To Corporate Houses
Corporations that deploy SD-WAN solutions can build higher-performance WANs through inexpensive internet at significantly lower costs than private WAN connection technologies, including Multiprotocol Label Switching (MPLS).
Using SD-WAN, enterprises can seamlessly manage their firewalls and routers and upgrade software and Virtual Private Networks (VPNs). These invariably make it easier for companies to manage remote clients through a centralised management interface that securely and efficiently routes traffic across the WAN directly to trusted providers and minimises costs by cutting maintenance and equipment costs.
The World Of Difference
Earlier, traditional WAN connected users at the branch or campus to applications hosted on servers in the Data Center. Here, dedicated MPLS circuits ensured secure and reliable connectivity.
Unfortunately, WANs were designed for a different era and are now deemed ineffective in today’s Cloud-centric world. Today, businesses resort to SaaS and IaaS applications in multiple Clouds. Plus, critical assets need protection as applications get accessed by several parties, including employees, partners, contractors, vendors and guests.
The earlier times had the WANs backhauling all the traffic from the branch offices to a Data Center, where advanced security services got deployed. The traffic between the source and Data Centers rested upon complex routing protocols, including transmission control protocol (TCP/IP) addresses and control list tables. Ultimately, the overall configuration led to delays, resulting in poor application performance, user experience and huge costs. Furthermore, users were to incur the expense of installing MPLS routers at each location. Another consequent effect was the upgrades on the software, which lasted longer than expected due to network complexities. These limitations stirred and paved the way for SD-WANs.
As the adage goes, modern problems behest upon modern solutions. Similarly, new business models drive and thrive on new network models. And this is where SD-WAN comes to the rescue. SD-WAN gets optimised for Cloud infrastructure and associates Cloud technology with mobile computing. It does so by separating the data plane and control plane of the network. The centralised management interface manages and monitors the traffic, while the single management portal reduces complexities, makes tracking applications easier, improves performance and accentuates operational efficiencies.
Key Features Of SD-WAN
The primary objective of SD-WAN is connecting end-users and applications, irrelevant of the location. SD-WAN provides end-to-end encryption over the entire network, prioritising traffic for business-critical applications and routing it via the most efficient pathway. However, opting for SD-WAN calls for several considerations:
Encrypted overlay network
Data services independence
Advanced security and VPN features
Optimising Large Network Setups
Web Werks has brought in new capabilities in partnership with FatPipe, the global leader of SD-WAN solutions and a holder of multiple patents for WAN optimisation products. FatPipe specialises in solutions that overthrow WAN failures, assuring business continuity.
The collaborative pursuit stands to reinforce and simplify WAN architecture through SD-WAN-enabled services. The association offers connection choices, wherein customers can avail of centralised control of their Edge devices, rapid scalability, and a lower TCO.
By leveraging FatPipe’s advanced SD-WAN capabilities, Web Werks’s customers get optimal end-to-end network connectivity between their branches and the Cloud.
The biggest upgrade is FatPipe’s acclaimed “Sat Booster technology”, designed for satellite traffic. This can be configured to minimise data flow via the LTE path.
This partnership stems from the rapid adoption of multi-Cloud and SaaS operations. To this end, Web Werks VMX, a robust cloud platform, along with FatPipe SD-WAN architecture, helps deploy a Private Cloud within the Data Center. It also supports intelligent software which seamlessly integrates Public Cloud application platforms.
