When it comes to SMPP applications, it’s the architecture that matters. Various applications are developed and available in and around Kannel. If you are a tech-savvy person and technology enthusiast most probably you can set up your Kannel and kick start your first SMS campaign in a couple of days.
Major hurdle you may face in due course of time in scaling out your solution in terms of increasing throughput. As the business grows, the problem increases. The absence of any proper PDU debugger tool, which can drill down any issue, poses a challenge for your support team while handling any technical issue reported by the end-user. Over and above TCP level error handling, and troubleshooting is also a big challenge. All these things can be handled by effective planning of System Architecture and using proper tools.
The architecture of any SMPP application is majorly decided on throughput requirements between ESME &SMSC and vice-versa. Handling traffic on a larger scale needs a hybrid approach while choosing the right kind of database for the right task. While open source SMPP applications and open-source Bulk SMS sender tools can help you get started with your average traffic, in the future you may feel the need to scale things in a more robust and reliable manner.
We at Power SMPP try our best to understand client requirements and suggest to them the right approach on how and where to use open source and the right time to adopt a proven proprietary application.
