With Zoho now offering more than 45+ applications to fit into the needs of most of the enterprises and these applications covering most of the standard business processes, there was always a need to develop custom applications or integrate other third party systems to exchange data. 

While it made sense to develop those applications and host on an external infrastructure for eg. an outbound calling application developed using VueJS , well integrated within the Zoho extensions and widgets ecosystem, still these applications have to be managed separately.
