Cloud Foundry is an open source PAAS Implementation, Pivotal based on a number of CF extensions that released its own commercial version of PCF. and deploying PCF to AWS as a reference implementation is the PWS. Current PCF -supported IAAS includes AWS, AZURE, GCP, VSphere, OpenStack. If you are just trying to deploy an application on a PCF platform, you can choose two ways to deploy directly to PWS, and the other is to deploy a pcf--directly if you

How do I know I'm done with IO?first, the event-driven model introductionTypically, when we write a program that server processes a model, there are several models: (1) Each time a request is received, a new process is created to process the request;(2) Each time a request is received, a new thread is cre

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization. The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall

It makes valuable CPU computing resources not wasted waiting for slow Io. Its behavior is intuitive. after sending an IO request, the user thread do

each block device or partition of a block device has its own request queue (request_queue), and each request queue can select an I/O Scheduler to coordinate the request submitted . The basic purpose of the I/O Scheduler is to arrange requests according to the sector code they correspond to on the block device to reduce the movement of the heads and improve efficiency. Requests in the request queue for each device are responded to in order. In fact, in addition to this queue, each scheduler itse

A. Almost every peripheral is done by reading and writing registers on the device. Peripheral registers are also known as "I/O ports, usually includes: control registers, State registers and data registers three categories, and a peripheral register is usually continuously address. There are two ways for the CPU to address the physical addresses of peripheral IO ports: One is I/O mapping (i/o-mapped) and the other is the memory-mapped method (memory-m

To use the File class, first observe the construction method of the File class. The common construction methods of this class are as follows: public File (String pathname)-> when instanti
