The difference between decentralization and distribution

1. In a system with many nodes, each node has a high degree of autonomy. Nodes can connect freely to each other to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form nonlinear causality through the network. This open, flat and equal system phenomenon or structure is called decentralization[ 2]
with the deepening of the interaction between subject and object, the continuous balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which is called decentralization.

2. Decentralization is a phenomenon or structure, which can only appear in a system with many users or nodes, and each user can connect and influence other nodes. Generally speaking, everyone is the center, and everyone can connect and influence other nodes. This flat, open-source and equal phenomenon or structure is called "decentralization"< Br > at the same time, "decentralization" is one of the typical features of blockchain, which uses distributed storage and computing power. The rights and obligations of the whole network nodes are the same, and the data in the system is jointly maintained by the whole network nodes, so that the blockchain no longer relies on the central processing node to realize the distributed storage, recording and updating of data. Each blockchain follows a unified rule, which is based on a cryptographic algorithm rather than a credit certificate, and the data update process needs to be approved by the user, so that the blockchain does not need the endorsement of intermediaries and trust institutions< The characteristics of br> de centralization:
centralization is first reflected in diversification. In the Internet world, there are no more than several portals has the final say. Various websites have begun to voice their own voice, express different choices and different hobbies, and these websites are distributed in every corner of the Internet world. Br > decentralisation is followed by the centralization of people, and decentralisation of content has become a trend, and people have become the key force to determine the survival of websites. It's a great change to build a website with indivials who lack interaction to gather talents and contribute their wisdom in the form of a circle. That is user-oriented, humanized< < br > decentralized content: < br > decentralization is the form of social relationship and content generation formed in the development of the Internet, which is a new network content proction process relative to "centralization"< Br > compared with the early Internet (Web1.0) era, today's Web (Web2.0) content is no longer proced by professional websites or specific groups of people, but is created by all Internet users with equal rights. Anyone can express their views or create original content on the Internet to proce information together< Br > with the diversification of network service forms, the decentralized network model is becoming clearer and more possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together< After that, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 became more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, made it easier and more diversified to proce or contribute content to the Internet, thus enhancing the enthusiasm of Internet users to participate in the contribution and recing the threshold of procing content. Eventually, every netizen becomes a tiny and independent information provider, making the Internet more flat and content proction more diversified.

3. Yes, decentralization: no domain name, no server, no central account, no operator, open fund pool, never shut down the network, with chain contract, no real name registration, automatic distribution of benefits, no tampering with the system, no hacker attack

centralization: to apply for a domain name, you need a server, you need a central account, you need an operator, the fund pool is not open, you can close the network at any time, you have no contract on the chain, you need to register your mobile phone number, you need to apply for cash withdrawal, and hackers can attack.

4. Compared with the traditional centralized storage and centralized cloud services, the two complement each other and expand the market of data storage and computing, which will constitute the two cornerstones of the future digital economy. China has efficient, stable and cheap power and network infrastructure, which provides sufficient soil for the development of decentralized cloud computing. Taking IPFs as an example, 90% of the total network computing power of IPFs is located in China. In the future, China will become the leader of IPFs. Taking xnmatrix as an example, it has become a global computing power leading decentralized cloud computing platform.

5. In fact, decentralization is equivalent to multi centralization. This is the characteristic of blockchain technology. Everyone has the right to participate. Now blockchain projects are very popular. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is now in the formal operation stage. It has also been selected as a key project of Hunan blockchain. The next step is to recruit enterprises to join the chain.

The difference between cluster, load balancing and distribution:

1. Linux cluster is mainly divided into three categories (high availability cluster, load balancing cluster, scientific computing cluster) (the following only introces load balancing cluster)

Load Balance Cluster

Load Balancing System: all nodes in the cluster are active, They share the workload of the system. Generally, web server cluster, database cluster and application server cluster all belong to this type

Load Balancing cluster is generally used for web server and database server of corresponding network request. This kind of cluster can check the servers that accept less requests and are not busy when receiving requests, and transfer the requests to these servers. From the point of view of checking the state of other servers, load balancing and fault-tolerant clusters are very close, but the difference is that they are more numerous

2. Load balancing system: load balancing includes DNS load balancing (more commonly used), IP load balancing, reverse proxy load balancing, etc., that is, there are servers a, B, C in the cluster, which are independent of each other. If any machine fails, it will not affect the operation of other machines, The algorithm with load balancer decides which machine will handle it. If your algorithm adopts round algorithm, users a, B and C will handle it respectively by servers a, B and C

3. Distributed refers to the distribution of different services in different places

cluster refers to centralizing several servers to achieve the same business
every node in the distributed system can be used as a cluster
clusters are not necessarily distributed

for example: sina.com, for example, has more visitors. It can make a cluster, with a response server in front and several servers behind to complete the same business. If there is a business access, the response server will see which server is not very heavy, and which one will be given to complete it

in a narrow sense, distributed is similar to cluster, but its organization is relatively loose. Unlike cluster, there is one organization, one server breaks down, and other servers can support it

each distributed node completes different services. If a node fails, the service will be inaccessible
