The trend of the last years is in area of cloud computing based
on various services
which are related to one or more particular fields such as
Software as a Service (SaaS),
Infrastructure as a Service (IaaS) and Platform as a Service
(PaaS).

   The cloud services are operated by different providers which
are usually oriented in
specific field such as storage or computing. The common
requirement from the users of cloud
services is to have an option for getting reports and analyses
tasks helping them to get
the over-view about cloud services usage. The challenge in the
terms of reporting and analyses
is in ap-proach of collecting data from the various systems,
store them somewhere and generate
reports with some results. The ideal scenario would be in use
of a traditional data warehouse
which is capable to collect data from the operational systems
and pass the data through
an operational data store for additional operations before they
are used in the warehouse for
reporting. Unfor-tunately the traditional data warehouse
implementations are too complex for
flexible and easy way how to extend their functionality and
mostly oriented for some particular
solutions of the 3rd parties. There is missing a way how to do
a simple integration with
other systems.

   This thesis presents another view on data warehouse focused
on data of the cloud ser-vices.
The cloud warehouse is a database used for reporting, analyses
and data synchronization. The data
stored in the cloud warehouse are collected from the
external/operational systems pro-vided as cloud
services. The data may pass through an operational data store
(ODS) for addi-tional operations before
it is used in the cloud warehouse for reporting. The cloud
warehouse maintains its function on three
layers: collecting, integration, and access. Collecting is used
to store raw data from
external/operational systems. The integration layer is used to
integrate data and to
have a level of abstraction from users. The access layer is for
getting data out for users.
This is definition of the cloud warehouse focused on data
storage of cloud services.

   Prototype implementation of the cloud warehouse is developed
and described in this the-sis.
