Is cloud computing a large scale distributed parallel computing method?

Cloud computing is a new model of IT resource provision, which can be simply understood as a data center, where computers can be automatically managed and dynamically allocated, deployed, configured, reconfigured and resourced, and software and applications can also be automatically installed. The components of cloud computing include hardware, software, and services. The hardware is mainly x86 or power machines.

Software includes software that manages computer automation, as well as software that is managed. Service refers to the construction and subsequent operation and maintenance of the cloud computing center. The cloud computing center provides its users with a virtual computer with software and applications, which may correspond to a physical machine, and may have multiple virtual machines corresponding to a physical machine.

The end user connects to the virtual machine through the network, which means that the user has a server with the software he needs to use. The user has certain permissions, and of course he can also install software that is not provided by other cloud computing centers.

Distributed technology is essentially a network-based computer processing technology. A distributed system is a set of logically and physically interconnected processing units. Its essence is the system-wide decentralized control of resources to achieve the collaborative execution of applications.

This type of system does not require a single computer to be very powerful.

Cloud computing is a type of distributed computing, which refers to the decomposition of huge data computing and processing programs into countless small programs through the network "cloud", and then through the system composed of multiple servers to process and analyze these small programs, the results are obtained and returned to users. In the early days of cloud computing, to put it simply, it was a simple distributed computing that solved the task distribution of the target and merged the calculation results. Therefore, cloud computing is also known as grid computing.

At this stage, it is said that the judgment of cloud services.

It is no longer just a kind of distributed computing, but distributed computing, utility computing, and load balancing.

The result of a hybrid evolution and leap in computer technologies such as parallel computing, networked storage, hot standby redundancy, and virtualization. If you want to know more, I recommend you to check out Speed Cloud, which is a full-stack cloud native.

A technology service provider that provides cloud-native applications and data platform products, including container cloud PaaS, DevOps, and microservices.

Cloud computing technology is based on three special cloud computing service models, all of which have the characteristics of popularity, effectiveness, flexibility, and user-friendliness. Therefore, the basic patterns of cloud architecture are:

1. Infrastructure-as-a-Service: Infrastructure benefits include computers, networks, storage, load-balancing devices, and virtual machines. These end-user hardware and software resources can be scaled up or down according to their needs.

2. Software as a Service: As the name suggests, this model includes software parts such as virtual desktops, various utility applications, content resource management, email, software, and others.

3. Platform-as-a-Service: In this model, the hosting service provider helps customers by providing a working platform, including the execution of runtime, databases, web services, development tools and operating systems, and customers do not need to manually allocate resources.

There are four deployment models for cloud computing, each with unique capabilities to meet different user requirements.

1. Public cloud: In this mode, applications, resources, storage and other services are provided to users by cloud service providers, most of these services are free, and some are paid according to the amount of use, and this model can only be accessed and used by the Internet.

2. Private cloud: This kind of cloud infrastructure is dedicated to serving a certain enterprise, and it doesn't matter whether it is managed by itself or managed by a third party, and it is responsible for it or managed by a third party. As long as there is no problem with the way it is used, it can bring significant help to the enterprise.

3. Community Cloud: This model is built between multiple companies with similar goals in a specific group, they share a set of infrastructure, and the enterprise seems to move forward together.

4. Hybrid cloud: Hybrid cloud is a mixture of two or more cloud computing models, such as a mix of public cloud and private cloud. They are independent of each other, but they are integrated within the cloud to bring out the benefits of a mix of cloud computing models.

Characteristics of cloud computing: distributed, decentralized. Networking as many general-purpose servers as possible to provide a good enough computing service.

The cost of a general-purpose server is very low, and there is also an advantage that is fault tolerance. Any server has a probability of downtime, but the fleet can control this downtime, and engineers don't need to be busy solving hardware failures all the time, but only need to replace damaged servers regularly.

Cloud computing is a concept that essentially integrates server hardware and software resources distributed on a network to provide services, such as providing large-scale computing, network storage, cloud applications, etc.

Cloud computing uses many technologies, and distributed computing is one of them.

Distributed:Cloud Computing:

It refers to the delivery and consumption model of services, and refers to the on-demand and easily scalable way to obtain the required services through the network. This service can be related to IT and software, the Internet, or any other service. This pool of resources is called a cloud.

The "cloud" is a number of virtual computing resources that can be self-maintained and managed, usually some large server clusters, including computing servers, storage servers, broadband resources, and so on. Cloud computing centralizes all computing resources and is automatically managed by software without human involvement. This allows application providers to focus more on their business without worrying about tedious details, which is conducive to innovation and cost reduction.

Difference Between Distributed and Cloud Computing:It's like moving from the old single-generator model to a centralized power supply model in a power plant. It means that computing power can also be circulated as a commodity, just like gas, water and electricity, which is easy to access and inexpensive.

The biggest difference is that it is transmitted over the internet. Cloud computing is the development of parallel computing, distributed computing, and grid computing, or the commercial implementation of these computer science concepts. Cloud computing is the result of a hybrid evolution of concepts such as virtualization, utility computing, IaaS, PaaS, and SaaS.
