Cloud elasticity refers to the ability of a cloud service to provide on-demand offerings, nimbly switching resources when demand goes up or down. It is often an immediate reaction to clients dropping or adding services in real time. Cloud elasticity is also known as rapid elasticity.
Atomic is a toolkit of variable java.util.concurrent.atomic package classes, which assist in writing lock and wait-free algorithms with the Java language. An algorithm requiring only partial threads for constant progress is lock-free. In a wait-free algorithm, all threads make progress continuously, even in cases of thread failure or delay. Lock and wait-free algorithms are also known as nonblocking algorithms. Nonblocking algorithms are used for process and thread scheduling at the operating system and Java virtual machine levels.
All java.util.concurrent.atomic package classes have the "atomic" prefix in their names. There are different types of atomic variables available in the java.util.concurrent.atomic package, including:
