With the rapid growth of the size of the data stored in the cloud systems, the need for
effective data processing becomes critical and urgent. This research introduces a study of
the most important characteristics of databases management systems: H
ive, SQLMR, and
MariaDB Galera. Hive is a cloud database management system. SQLMR is a hybrid
system, which depends on the integration between the cloud and traditional systems
capabilities. While MariaDB Galera is a traditional database management system
developed to cope with the cloud characteristics. In this research, we show the most
important developments that have been on those systems, and then we compare their
performance in data processing based on the execution time of query operations with the
change of the volume of data. That is to identify the performance of those systems
practically and to know the developing requirements for access to optimized data
management system, and to help users in the selection of the database system that achieves
their requirements in terms of availability and scalability.
This project aims at introducing the concept of Infrastructure as code, one of the most important and current trends in information technology, which was introduced in 2011 by the latest Amazon cloud platform. To recognize this concept, "Terraform" o
ne of the most important IAC tools, has been used with one of the most famous cloud computing platforms "OpenStack" . This project is in line with new concepts and is a simple reference for our fellow students if they want to research and study topics related to these concepts .
This study aimed to clarify the concept of cloud computing, their
characteristics and components, as well as the advantages and
disadvantages of the applications made available ways to take
ح .advantage of the Library environment
This study came
out with a set of the results which demonstrated
the importance of cloud computing to libraries by providing large
storage areas and expenditures, and the possibility to take
advantage of them do not require high skills, experiences.
problems relating of information security and privacy is a challenge
in dealing with them
