Cloud Database
Dac‐Nhuong Le, Souvik Pal, Prasant Kumar Pattnaik · 2022
Cloud computing is an emerging technology that provides software and hardware resources to users on a pay-per-use basis; and the surge in demand for anytime anywhere access to meet the current needs of users has resulted in the concept of mobile computing. Both aim to provide service to users as per their requirements; and cloud computing provides better flexibility in terms of PaaS, SaaS, and IaaS. Database handling is an important consideration of the above type of computing environments. Many researchers are proposing solutions to database issues using SQL and NoSQL space suitable for the cloud computing scenario. Data in the cloud database is classified as structured and unstructured data as well as big and small data. In this research we have conducted a study of cloud databases as well as its classification in terms of ACID- and NoACID-based database transactions. Again our work focuses on the architectural issues of database as a service (DaaS) based on the live migration from ACID-based database to NoACID-based database and vice versa.
