ЁЯУШ Quick Notes for Important Topics

What is MapReduce?

MapReduce is a programming model used in cloud computing for processing large datasets across distributed systems. It consists of Map and Reduce phases for dividing and combining data efficiently.

What is Virtualization?

Virtualization is the process of creating virtual versions of hardware, operating systems, storage devices, or servers to improve resource utilization and reduce infrastructure costs.

What is SOA?

Service Oriented Architecture (SOA) is a software design model where services communicate over a network. It improves scalability and interoperability between applications.

What is Cloud Security?

Cloud Security includes technologies and policies used to protect cloud-based systems, applications, and data from threats and unauthorized access.
