SD-WAN is serving enterprise networks, just like virtualization did for enterprise data centers ten years ago. But I think SD-WAN is developing faster.
This is some new technology, but also a macro trend, such as how virtualization changes the data center, thereby affecting the way everyone designs and runs their IT infrastructure and applications. SD-WAN is a natural progression.
As companies begin to adopt SD-WAN, they are shifting from a traditional router-centric WAN approach to a business-oriented network model that ensures superior user experience, resilience, and business continuity while providing a high level of WAN And application performance.
Due to our geographic location, it is not surprising that SD-WAN is rapidly adopted. We are a large country, but our network channels to connect and lead to remote areas are relatively narrow. With businesses spreading across the country, networking is a real challenge.
Routers and SD-WAN
use traditional router-centric methods, and companies are forced to comply with network constraints. The WAN architecture is rigid, with complex management and slow adaptation. Each branch also requires a separate firewall and WAN optimization equipment.
In contrast, by replacing routers at the edge of the network, SD-WAN can simplify and consolidate the WAN infrastructure. SD-WAN, WAN optimization, routing and firewall are unified into a business-driven platform. Depending on the security status of the application, the traffic can also be linked to next-generation firewalls or cloud-based security services. This thin-edge architecture can significantly reduce costs.
SD-WAN provides enterprises with the flexibility to use various combinations of transmission services including broadband Internet to safely connect users to applications without affecting the performance of the network or application. Ultimately, the network will become a business facilitator so that business can be carried out based on a centrally defined strategy.
Any enterprise that migrates distributed branch offices and applications to the cloud can realize the advantages of SD-WAN.
Companies are trying to become more competitive, more agile and enter the market faster. It is almost impossible to achieve this agility without the next-generation agile network. Today, every business has a high-level business goal-whether it is digital transformation or business agility.
Another important aspect is the user experience. If you consider the current and past five years of market conditions, applications may not already reside in the data center, but in most cases, they are moving to the cloud.
In the traditional network architecture, branch users connect to the application through a traditional private network.
Multi-Protocol Label Switching (MPLS) networks have been performing well for more than 20 years because applications are centrally hosted in the data center. However, if these applications are moved to a remote location, traditional networks are not necessarily the best way to connect users to the applications. This can severely affect performance, user experience and ultimately corporate productivity.
Users often complain that because they are directly connected to the Internet, the performance of using cloud applications at home is very good, but when working in a branch, it is very bad. In many cases, this is because the traffic needs to be transmitted back to the data center and then back to the cloud, which causes delays and congestion, and affects performance.
This also means that if you want to make changes to a huge branch network, it may take weeks of planning, change control, and various operations to achieve this goal-which is very complicated.
This is where the appeal of SD-WAN comes into play. The agility and operational efficiency it provides can not only increase user productivity, but also make it easier, more efficient and efficient to manage the network. You can define a strategy centrally and launch it to complete.
The above is the introduction that enterprises should take SD-WAN seriously.
