For anyone considering Software Defined WAN, choosing service insertion is one of the most important aspects anyone can make. Without service insertion, a lot of networks will often run into hurdles that they can’t easily overcome. As its name suggests, service insertion is basically inserting services in the existing network framework with the focus being on improving the user experience. For a long time now, users of the SD-WAN framework have been adopting more and more use of insertion services to meet needs their current network structures are struggling with.
The need to expand the capabilities of the current networks has also been one of the most looked at aspects to success. While most current networks have the capability make changes, the addition of the needed services to the current network through service insertion has been chosen as the way to handle extra capacity.
What is Service insertion and chaining?
Service insertion and service chaining are two closely related services that have been made possible by Software Defined WAN framework for their customers. In summary, they both allow for the spinning up of new services to an existing Wide Area Network to enable new possibilities. For example, whenever a customer installs a new network service, they set up an (IDS) Intrusion Detection System and a firewall as security measures.
These two can take care of any security issues that may crop up such as a hack or virus breach. Some people, however, choose to use a security stack to up the level of security which is both costly and consumes lots of time. For the best result which saves both time and money, service insertion is chosen on the wide area network. It affords a level of flexibility not possible in other ways.
What you can do with Service insertion?
With service insertion on Software Defined WAN, you can easily keep tabs on the traffic without incurring exorbitant costs or other issues. Rather than having the whole network scoured for security vulnerabilities, you can insert a security stack that on a specific channel of the network. In this way, the security stack only takes care of the traffic in which you are interested.
This saves the security setup lots of time and money as it is a lean yet effective way of securing a Wide Area Network. The security system can, for example, be made to work on specific stacks of information to save on time and costs. There are some channels whose data volumes will not need to be checked for viruses and malware such as internal communications. In this way, the need to go through a data batch that is not needed for scanning will be eliminated to avail resources for urgent matters.
From this information, one can conclude that service insertion has three advantages. The first one is saving money as it allows people to include only the services they want in their WAN. You get to pick the services in terms of the volume of data, the types of communication and other aspects. Secondly, service insertion saves on time as one does not need to install a whole new system. The existing structure is merely fitted with the needed software then leveraged to provide for the needs of the expanded network.
Many people agree that the adoption of SD WAN is as easy as switching the guy you deal with but with lots of benefits. Lastly, service insertion allows for the better functionality of the WAN.There is increased reliability, lower operation costs and the ease to switch the service as needed. This level of flexibility is like no other on the market.
