Main advantages are, first, a reduction of application complexity down to standard widely used components and systems, using LAMP. Second, database design is focused on efficiency in a distributed (cloud) environment, however large and transaction intense applications will quickly run into performance issues without specific optimizations, de-normalization, and indexing. This cloud model, finally, allows changes to one data model and data sets from everywhere in the cloud securing integrity independent from the source of change.
The V.O.I.T.H. cloud is a database and application framework developed to combine features as (1) flexible dynamic data modelling in a virtual database framework,
(2) online access via web interface and RPC API interfaces,
(3) integration of multiple server instances in a cloud environment which is designed in a three-tier architecture of a data structure model, a data versioning and change distribution model, and the content management itself. The three tiers keep ownership in distributed environments and allow integrated locking in different levels of strength.
(4) Basic database design is kept in independent relational-transactional systems, but (5) the overall cloud design follows the hub-spoke principle of distributed instances.
