Storage allocations for Java programs in memory:Heap Area:1. All objects are stored, each containing a class-corresponding information. (The purpose of class is to get operation instructions)2.JVM only one heap area (heap) is shared by all threads, and the heap does not hold basic types and object references, only the object itselfStack area:1.

Concept of the javaweb framework-its own object storage pool and the concept of the javaweb framework Original Design:When a website provides services, many objects such as bean and dao are created frequently. However, these objects can be reused.Design Concept:The ObjectPool of the object connection pool uses the single-State design mode. It comes with a thread

"PHP SDK for Openstack/rackspace APIs" uses object storage services

With the evolution of high-performance computing from traditional host to networked cluster, the traditional host-based storage architecture has gradually developed to networked storage, and the trend of computing and storage separation is becoming more and more obvious. In view of the shortage of SAN and NAS, the research of the new file system-
