On demand message queuing providers enable custom integration of services through API or coding. In some situations using an on demand message queuing service adds more value, for example, in the situations of decoupling the components of your application. However, in the situations of integration between external services and given the current economic conditions, enterprises and SMB’s are focused on efficiency and cost savings looking to adopt SaaS models more than ever before.
The SaaS integrators provide an extra level of abstraction over the on demand message queuing providers, for example, a visual paradigm of integration with an emphasis on integration through configuration rather than, integration through coding. This would increase the inclination towards SaaS integrators over integrating using coding or using on demand message queuing providers.
