SD–WAN Accelerating Network Performance
According to 2016’s State of the WAN report, traditional WAN exhibits performance limitations such as latency issues and packet loss at a higher level. In this report, two of the factors among the top five were related to network performance, which is of crucial importance. This is the major reason behind fundamental shift from WAN to SD–WAN. As we move toward SD-WAN solutions, it is necessary to understand how various aspects of SD-WAN can provide discrete solutions to improve performance of the network.
What is SASE?
Secure Access Service Edge (SASE) is a combinational network architecture of SD–WAN and Remote Access VPN that combines the capabilities of both and delivers them as a service. It combines functionalities and capabilities of SD–WAN and VPN with cloud native security functions, for example, firewalls, secure web gateways, zero trust network access and cloud access security brokers. SASE vendors offer these cloud-delivered functions as a service.
DIY vs Managed SD-WAN
The world we live in now, is being driven by the explosion of data. With every passing day, the data traffic increases and creates new challenges to manage the infrastructure. Cost Optimization and Service Delivery are the two critical pain points of any organization. In the domain of network connectivity, SD-WAN provides bandwidth efficiency with lower cost and seamless communication. The key benefit in comparison to standard WAN, is its significant application performance without compromising the data privacy and security.
SD-WAN or MPLS
The proliferation and maturation of network technology enthused multiple opinions among the vendors about the benefit and worth of SD-WAN and MPLS in the present era. Since most opinions revolve around the inception of the latest technology overpowering the preceding ones, it is anticipated that SD-WAN would take over the MPLS in the near future.
SD-WAN Going SASE
Wide area networking (WAN) is a traditional networking solution based on multi-protocol label switching (MPLS). In such solutions, the reliability of the connection depends upon the pre-definition of communicating nodes. But these high-performance networking links between the two sites face limited bandwidths and have some other physical constraints. Hardware defined pre-setup is the primary cause in WAN to shift towards a software defined – wide area networking (SD-WAN) solution.
Top 9 Things to Look for in an SD-WAN Supplier
Software-Defined Wide Area Network (SD-WAN) is being increasingly adopted by organisations of all sizes due to its myriad benefits. Even during the challenging times of COVID-19, when organisations are running on significantly fewer employees, the adoption rate for SD-WAN deployment remains high. The reason behind this high adoption rate is the realisation of the critical value offered by transforming from traditional WAN to SD-WAN technologies.
Network Visibility With SD-WAN
Software-Defined Wide Area Networking (SD-WAN) is fast becoming one of the most popular network technologies for enterprises. Due to its quality of services, enhanced application performance, minimal architectural complexity, simple set-up, and reduced cost, SD-WAN is increasingly popular and rapidly transforming network technologies. According to Kentik’s data collection reports, it is expected that 95% of enterprises will have moved from traditional WAN to SD-WAN architectures within 24 months, due to the vital factors mentioned below.
How To Deploy A DIY SD-WAN?
We have seen a rapid increase in the deployment of SD-WAN by organisations of all scales. It is essential to understand the various methods of SD-WAN deployment. Generally, there are two approaches to deploying software-defined networking: managed SD-WAN providers and do-it-yourself (DIY) methods. In the latter approach, any external service provider is not hired for the deployment of SD-WAN. Instead, it is managed and set up by the company’s own IT teams.
SD-WAN Helping Work From Home
COVID-19 dominates working life today. Office staff throughout the world have settled into their work-from-home set-ups. Nevertheless, a significant portion of the global population do not have access to broadband internet at home; even more have weak internet connections. Working from home rarely offers the high-quality connections employees enjoy at the office. Freelancers also suffer a similar problem. Individuals and organisations are therefore looking for technologies that will enable productivity as working from home continues.
Digital Transformation with SD-WAN
SD-WAN (Software-Defined Wide Area Network) is a virtual wide area network that has revolutionised how users connect to their applications, no matter where the application resides. Previously, 80% of applications were located in branch offices or core datacenters, and communication was through a leased line, usually MPLS. This has changed today. With the emergence of the public cloud and the adoption of the public cloud by enterprises, applications can be literally anywhere.
