Types of Grid

Cluster
Cluster means, collection of homogenous nodes or machines. When same kinds of machines are grouped together to completethe task of any organization’s specific department, cluster is used. All machines in the grid are locally networked and the resources are of the same architecture and operating systems.Selecting the application software and security policies for cluster grid is usually simple compared to other abstruse types. Cluster is used for only one department of an organization.For example, any department in an organization is known as cluster.
Intragrid
Intragrid means, collection of heterogeneous nodes or machines. The grid system incorporates the job scheduling components by which grid functions in an efficient manner. Here, there can be multiple departments connected to grid provided they are from the same organization.
As department augments, maintenance of a grid also increases.  For example, there may be polices that defines which department’s priority is high. Also, security becomes an important issue when numbers of departments are coherent. Sensitive data can be circumscribed to access from other departments. Dedicated grid machines may be added to increase the quality of service for grid computing, rather than depending on scavenged resources. For example, one organization and multiple departments in it connected to each other.
Intergrid
The primary characteristics of an Intergrid incorporate dispersed security, multiple organizations, and remote/WAN connectivity. The highest level of security is usually needed by engineering firms, life science industries, manufacturers, and by business in the financial industry.
Here, there are multiple organizations and multiple departments of it connected to each other.

Characteristics of a Good Programming Language

Till now there are many high level languages which are very popular, and there are others, which could not become so popular in-spite of being very powerful. There might be many reasons for the success of a language, but one obvious reason is the characteristics of the language. Several characteristics believed to be important with respect to making a programming language good are briefly discussed below. Simplicity A good programming language must be simple and easy to learn and use. For example, BASIC is liked by many programmers only because of its simplicity. Thus, a good programming language should provide a programmer with a clear, simple and unified set of concepts which can be easily grasped. It is also easy to develop and implement a compiler or an interpreter for a programming language that is simple. However, the power needed for the language should not be sacrificed for simplicity. The overall simplicity of a programming language strongly affects the readability of the pr...

Angular 4 and Firebase Authentication: Email/Password

In our  previous  article we saw how to create authentication module using Google identity provider. Now we will see how to implement Email and Password authentication using Firebase. We will use Bootstrap form to create intuitive user interface for sign-up and login using Email and Password. Step 1: Create signUp component. ng generate component signUp Step 2: Create custom form in sign-up.component.html file. The result of above code: Step 3: Add two functions for creating the user and login using Email and Password in src/app/providers/AFAuth.ts file. Step 4: Call createUserWithEmailAndPassword function in service from sign-up.component.ts. Step 5: Update routing configuration in app.module.ts  to include signUp component. Step 6: Update Login form to have Bootstrap form. The result of the above code. Step 7: Enable Email/Password component in Firebas...

Angular 4 and Firebase Authentication: Setup

If you have come to this article, it means you are keen to learn new technology and that too Firebase. I love Firebase because it provides all basic but important features of any web application. Take for example, authentication, which is cumbersome and risky if not implemented with utmost care. And when we have the integration of Angular and Firebase, it becomes a lot easier for a developer to build such crucial modules in less time with minimal efforts. In this article we will create a simple Angular application using Firebase. I am going ahead with the understanding that you know the benefits of Firebase and have little knowledge about it. There are plenty of posts out on the web if you are behind. Step 1: Install Angular CLI (if not installed). npm install -g angular-cli Step 2: Create new Angular 4 project. By default now angular CLI will create Angular 4 project so you need not fret. ng new firebase-authentication Step 3: Check whether the ne...
