A cloud-PBX solution built on a cloud-native platform has benefits such as effortless scalability, instant elasticity, and granular flexibility. These are benefits associated with a microservice software design and serverless deployment in a public cloud. However, many cloud-PBXs are built with a monolithic PBX software or virtualized PBX software that run on dedicated servers in a private of public cloud. While being labeled as cloud-based, they still cannot take advantage of the benefits that a cloud-native building practice bring.
A self-contained monolithic unit makes it very hard – if not impossible – to scale or change individual components separately. Replicating virtualized software on new machines requires manual work, and load balancing between servers must be taken care of. It is also harder to maintain and follow a unified scaling procedure on every site.
Furthermore, closely linked to scalability is the charging model. Typically, the charging model for servers running in the cloud is per server used, not per traffic usage.
If you expect high fluctuations in your customers’ traffic volumes, your cloud-PBX solution must be able to handle this. The cloud-PBX functionality must provide the elasticity required for dynamic traffic fluctuations.
As with scalability described above, dedicated servers in the cloud aren’t going to scale up or down instantaneously or automatically to address sudden increases or decreases in traffic volume.
A monolith is constrained by the functionalities already provided in it. This means that the possibilities to build what you want, and to open up for use cases not known today, is significantly limited. In a PBX monolith, it is hard to adapt the functionality to accommodate specific use cases or to address cases not enabled in your pre-paged monolith.
Integrating the PBX monolith to your application logic without having to re-build or change the logic is also challenging.
