Distributed Computing Why it is Popular

by
Distributed information systems are becoming more popular as a result of improvements in computer hardware and software, and there is a commensurate rise in the use of the associated technologies.

Why distributed computing so popular

  • With the increasing desire for business-to-business (B2B) communication and integration, technologies such as Service-Oriented Computing (SOC), Semantic Web, Grid, Agents/Multi-agents, peer-to-peer, etc., are receiving a high level of interest nowadays.
  • Due to the revolution in the internet, implementation of SOC B2B integration (e.g. e-commerce, e-government, and e-healthcare) is popular

Where lacking

  • Building Web Services comprehensively needs further improvement, for instance, Quality of Service (QoS).
  • Detection of service availability to achieve self-healing in the invocation process
  • Service reuse, how best to define atomic services
  • Service composition

Future computing

  1. Meanwhile, it should be noted that Web Services play only a partial role in evolving distributed information systems. With the development of future computer hardware, software, and business requirements, many other technologies will probably emerge that will serve particular business goals better. 
  2. Therefore, much recent research has been focusing not only on individual technologies in distributed systems but also on the possibility of combining currently available technologies to improve business outcomes.
  3. We concentrate mainly on Web Services and technical issues associated with current Web Services standards, but we also give a brief overview of three other distributed technologies, namely Grid, agents, and Semantic Web, which can work with Web Services. Thus, it concentrates initially on the background of services in distributed information systems, then it introduces Grid, agent, and Semantic Web technologies.

Web services Vs distributed computing

After that, it discusses several technical aspects of Web Services in current distributed information systems, in particular, general Web Service availability and performance issues and the possibility of combining agent technology and Web Services to provide an improved understanding of service availability. 

We then introduce JSON (JavaScript Object Notation), which may provide an alternative to current approaches that will deliver better Web Service Performance and discuss service composition, illustrating it with implementation from the EU Living Human Digital Library (LHDL) project.

I have shared 7 amazing AWS interview questions for your quick reference. 1). What is AWS? Amazon Web Services (AWS) provides on-demand computing resources and services in the cloud, with pay-as-you-go pricing. For example, you can run a server on AWS that you can log on to, configure, secure, and run just as you would a server that's sitting in front of you 2). What you can do with AWS? Store public or private data. Host a static website. These websites use client-side technologies (such as HTML, CSS, and JavaScript) to display content that doesn't change frequently. A static website doesn't require server-side technologies (such as PHP and ASP.NET). Host a dynamic website or web app. These websites include classic three-tier applications, with web, application, and database tiers. Support students or online training programs. Process business and scientific data. Handle peak loads. AWS Questions 3). What is the Security group? A security group acts as a virtual fi

These interview questions help you to read quickly. The below set of interview questions help you like a tutorial on Hyperledger fabric. Hyperledger Fabric Interview Questions 1). What are Nodes? In Hyperledger the communication entities are called Nodes. 2). What are the three different types of Nodes? - Client Node - Peer Node - Order Node The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery. 3). What is Channel? A channel in Hyperledger is the subnet of

How to Decode TLV Quickly

In TLV, the format is Tag, Length, and Value. The TLV protocol needs this type of data. Here you will know how to decode TLV data.  According to IBM , TLV data is three parts. The tag tells what type of data it is. The length field denotes the length of the value. The Value-field denotes the actual value. Structure of TLV. TLV comprises three field values.  Tag Length Value How to Decode TLV EMV formulated different tags. They have their meanings. Usually, the Tag and Length together takes 1 to 4 bytes. 1. The Best example for TLV. In the below example, you can find the sample TAG, LENGTH, and VALUE fields. [Tag][Value Length][Value] (ex. " 9F4005F000F0A001 ") where,  Tag Name =  9F40 Value Length (in bytes) =  05  Value (Hex representation of bytes. Example, "F0" – 1-byte) =  F000F0A001 In the above message, tag 9F40 has some meaning designed by EMV company. Here  you can find a list of EMV Tags. 2. How to read the TLV Tag: 1 or 2 bytes. Length: Length of the Value
