The SD-WAN implementation provides a flexible and automated way to turn traffic from one side to the other. The main SD-WAN architecture has only a few basic features.
- Lots of pages
- Multiple connections between site and subnet
- The administrator
As organizations take the lead in the cloud and digital transformation – the development of recent diseases promoted – they understand the fact that traditional networks have not been created to cope with the complexities and complexities of work.
This, in turn, will lead to an increase in flexible and SD-WAN Deployment, which analysts predict will increase from $ 1.9 billion by 2020 to more than $ 8.4 billion by 2025.
Changing the configuration of a network is an important task, so, of course, you need to understand and plan how it will affect the entire network – pages, loops, applications, and more. One of the best ways is to break the system into three steps:
- Foundation plans
- Confirm the distribution
- Ongoing service review
The installation process is simple, but requires diligence: you need to check the performance between the user, the application, the network and the cloud service.
This in turn helps the forecasting process and the negotiation stage. The most common requirements for this approach include installing and locating all internal applications, registering SaaS and IaaS applications, and configuring MPLS and an efficient Internet connection for potential traffic. There are tools on the market that help NetOps members do all of this as it is almost impossible to do it manually.
Once the plan is complete, installation and commissioning will begin – and here you can do it quickly and efficiently. The transfer system allows you to view SD-WAN policies for application performance, traffic mapping, DSCP and provider channels and check and verify application performance at the end.
In the process, NetOps can also use bandwidth usage, QoS tagging, and SD-WAN authentication to isolate problems by diagnosing the cause of slow resolution. The latter system performs the transfer through rich visual observations, custom dashboards, status, reporting and rapid detection needed to effectively control SD-WAN.
Interruptions often occur with the SD-WAN Deployment:
Although SD-WAN is rightly seen as a way to eliminate the prevalence and efficiency of traditional WAN solutions, there are various problems that can lead to the development of the technology itself.
The first is the lack of a clear vision for the use of technology. In the SD-WAN record sound of recent years, where technology is the “next thing,” some organizations have no specific business idea in the configuration. Anything can lead to this: customers do not know what to order from their suppliers, sellers do not tell customers what they want to sell, and so on – not who it is any cause or effect.
Security can be another complex issue: although all SD-WAN solutions have security features (but some actually have advanced network security features, such as next-generation firewalls [NGFWs]), these protections are not the same. Therefore, it is not necessary that they address all the threats of this system, as SD-WAN refers to the public internet as the network channel it uses. Companies are using other devices to pay for increased exposure, which disrupts IT infrastructure and can lead to their own threats, such as vulnerabilities at the end of the network.
In addition, the management of connections between different branches of the company can be more complicated by using SD-WAN than other MPLS or other traditional WAN settings: Connections between hundreds, hundreds or even thousands of words where the account is easily used SD -VAN. , but the coverage required for these connections can be difficult. It takes more work and effort to design and manage than a traditional WAN integrated communication architecture. In fact, this is due to the reliability of SD-WAN and the public Internet.
Last but not least, it’s important to think about how SD-WAN hopes to improve the performance of many domains – such as remote cloud and application (SaaS) services such as Microsoft 365, where databases and branches are located. Technology can handle this load, but your engineers are responsible for the project at first start-up and then design and implement SD-WAN in the same way. If not, it could be a problem.
Aruba SD-WAN expert Nav Chander explains that underestimating the complexity of SD-WAN is not a common problem: “We have seen many companies ignore the complexity of redesigning WANs to allow applications to migrate to SD-WANs – without any problems or choices. Today’s MPLS solutions, regardless of the importance of their SD-WAN capabilities, are capable of providing MPLS and SD-WAN QoS quality to give the application users the greatest experience possible. ”
Best practices for SD-WAN simplification:
Centralized management has emerged as an effective solution to facilitate SD-WAN distribution management. A central dashboard with a central panel that covers all parts of the network will help reduce the proliferation caused by the conditions mentioned above. As part of this process, the use of SD-WAN simplifies business idea submission policies and application category templates. , a variety of automated processes that increase network performance for application performance.
Security issues can be simplified by integrating the necessary network security tools into the SD-WAN itself for use with the solution. SD-WAN installation should connect services to the best network security solutions, both hardware and to facilitate integration. It is advisable to set a specific strategy for specific threats – that is, the threats to which your business is most vulnerable.
Lastly, make sure that SD-WAN supports external storage devices that work only externally, such as information storage and event management (SIEM). If your SD-WAN solution has the necessary monitoring and testing capabilities to streamline program traffic (in real time) and manage performance, connectivity, storage and reception, traps can be greatly reduced. This means collecting data from hundreds of applications per day. This stores large data that you can rely on to determine the measurements mentioned above.
In addition, SD-WAN solutions, such as the Aruba Edge Connect SD-WAN platform, allow for wireless learning capabilities that reshape and optimize the dynamic network, thus enhance the user experience. By creating this knowledge base, it will be possible to find appropriate answers to various questions, such as predictions and automation.
