What is cloud computing?

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

Cloud computing is very important as it allows people access to the same kinds of applications through the internet. … This means the device accessing the cloud doesn’t need to work as hard. By hosting software, platforms, and databases remotely, the cloud servers free up the memory and computing power of individual computers.

Benefits of cloud computing :

  • Reduced IT costs – Moving to cloud computing may reduce the cost of managing and maintaining your IT systems. Rather than purchasing expensive systems and equipment for your business, you can reduce your costs by using the resources of your cloud computing service provider.

  • Scalability – Your business can scale up or scale down your operation and storage needs quickly to suit your situation, allowing flexibility as your needs change. Rather than purchasing and installing expensive upgrades yourself, your cloud computer service provider can handle this for you. Using the cloud frees up your time so you can get on with running your business.

  • Collaboration efficiency – Collaboration in a cloud environment gives your business the ability to communicate and share more easily outside of the traditional methods. If you are working on a project across different locations, you could use cloud computing to give employees, contractors and third parties access to the same files.

  • Flexibility of work practices – Cloud computing allows employees to be more flexible in their work practices. For example, you have the ability to access data from home, on holiday, or via the commute to and from work (providing you have an internet connection)

  The popularity of Java script grows every day. It’s definitely the best scripting language which allows creating exciting  interfaces and simplifies the development of web applications, being a perfect open source app development software and making the sites interactive and convenient to use. The Javascript web development frameworks are issued and updated daily and that’s why it is difficult at times to go with the tides and understand which famework is most suitable and best matching for the project. Before choosing a web app framework to apply the requirement  and needs of the project to be taken into consideration. The advantages of the frameworks Javascript  framework is a number of features and functions written in Javascript language and ready  for the usage of the developers. These features simplify the interaction between the app and server and speed up the manipulating of the web page or app elements. The main advantage of using a web application development  frameworks is the fact that it provides immediate reaction to the user interacting with the site immediately. The basic content of the traditional sites without frameworks is stored  on the server and any new content , which is necessary to be upload requires reloading of pages. When frameworks are used , only the necessary blocks of a website are reloaded. Some of the most advantageous benefits of the frameworks ‘usage:
  • COST: The cost of the app development for websites decreases due to the JavaScript frameworks because they are free and open source code.
  • Development speed: Java Script frameworks have good documentations. Some of the JavaScript frameworks are supported by such giant companies as Google etc. Due to such a lot of information, the speed of development increases.
  • Efficiency: The usage of the pre-created functions and templates allows to carry out the projects more effectively. The developers have to write less code, which results in delivering projects meeting higher standards and more quickly.
Most used and popular frameworks— JavaScript frameworks have now become one of the most preferred web app development platforms for modern single page apps, social networks, e-commerce products and other software solutions creation. At present, without using frameworks, the development of modern web products has become almost impossible. There are Some companies are still using classical Java Script software incurring higher development costs. As a consequence of classical JS complexity, lot of frameworks have appeared in the market, but the solid leadership in the software development market belongs to these three: Angular, React and Vue.   Angular Angular is a cross-platform framework which keeps to the  MVC architectural pattern and supports a weak link between the display, data and logic of the components( integral parts of the app).  Angular shifts a certain part of server services to the client side and consequently the server workload decreases and the web application becomes lighter. Due to Typescript the project code becomes clear , convenient for developer’s understanding and contains fewer errors. Angular strong points are remarkable documentations and references. One of the week points of Angular is the high learning curve for the projects because a JavaScript developer  should know for instance , Type Script to start working with framework. It consequently makes the project  fulfillment  more difficult, especially the work is passed from one team to another. Another drawback of the Angular framework is the frequent release on the new versions. The 8th one already released in June, 2019.   React.js React—is a java script library with open source code for user-interfaces development. For the first  time React was used in 2011in the face book newsfeed, then in 2012 in Instagram. React is still being developed and supported by  Face book and Instagram. It can be used not only for browser-based web apps but also for mobile apps. The aim of the framework is to provide high speed , simplicity and operability of the apps on various platforms. However, React is not a full-fledged Framework, but  a function library. To use it as a Framework, other third party libraries should be attached. React strengths are speed, lightweightness, cross-platform format  and big community. The weakness is the necessity to use third party libraries for complete work which complicates the development process. Another drawback of the library is that it does not follow the standards in HTML or CSS CODE AS Angular and Vue.js do.;   Vue.js Vue– is a progressive framework for user interfaces creation. Vue was made fit for gradual implementation  unlike Angular or React. It means progressive framework  gradually starting from certain pages, which makes the development much easier. The Vue.js creator is Even and You and the framework is widely used in Chinese companies. Not so long ago the repository management  GitLab also switched to Veu.js. Vue deals with presentations layer tasks in the first turn, it simplifies the integration with other libraries and existing projects. Vue coopted the best features of Angular and React- the speed and lightweightness and the possibility to support such technologies as Type Script and JSX. However along with this the Vue frame remained true to the principles of CSS and HTML code writing. It facilitates quick web application development and makes the processes of project development and support easier. Thus , for any developer who knows the basics of the front-end technologies will not be a problem to develop or support the projects on Vue. At present, a small community can be called a weak point of the Frame work as no big corporations support it.  Nevertheless, popularity of the framework grows every year.   What to choose? Every project is unique in its own way and  before starting the project detailed analysis and evaluation is required. However, there are certain key aspects, which help to choose a particular technology for development: Speed and simplicity of project development and support. The speed of the development depends on the technologies, already used in the projects. In case Type Script or JSC have already been applied then  Angular or React correspondingly needed. But in case the project from scratch, it’s better to choose Vue .js due to its compliance with standards. Trends: All the frameworks are popular and will keep the leadership in the modern development marketin the coming years. It will not be a mistake to choose any of them . However Vue is vigoursly gaining popularity, followed by React.   Mobility and Stability: Supposing  one framework is chosen and then decided to switch to another one and Vue. js is the best choice in this case because re-writing the projects on Angular or React will mean that the developers will most likely need to switch Type Script or JSX code to classical Java Script and HTML correspondingly. One more important aspect to consider is the frequency of Frameworks update. Angular has serious updates issued every 06 months, React approximately once in a year. Vue is more stable in this sese and has serious updates once in several  years. Java-Script-Angular-Node-React-Vue JS-Python-Django Training and placements by DOCC Kolkata.

Angular 9 is the most preferred framework for creating interactive components of a website. It was designed as a full-featured JavaScript framework to enhance simplicity and efficiency. Developers find AngularJS very effective especially in creating dynamic, single page apps, and supporting MVC (Model View Controller) programming structure. As the business environments become highly competitive, AngularJS has emerged as the super hero because of its intuitiveness and rich features. The popularity of Angular 9: Today, AngularJS is one of the frameworks that do not make the Model View Controller look skewed and together along with NodeJS, it simply works great with both the technology understanding same notations. Some frameworks simply bundle together the existing tools which make app development very difficult. However, AngularJS was carefully engineered to ensure that every tool works optimally and delivers great results. After its release in 2009, AngularJS popularity has grown steadily and shows no sign of slowing down. But why is Angular becoming so popular and surpassing other frameworks? Here are a few samples of developers’ views after using the app. Pros of  Angular Apps: When AngularJS 4 was released in March 2017, it made JavaScript to be named the best programming language of the year. The regular Angular updates have particularly made developers, and users get a special attachment to their apps because of enhanced security and features. Here are additional pros of Angularapps. Time-saving: Projects that previously used to take many months with other frameworks can now be completed faster with AngularJS. All that AngularJS framework requires is splitting the app into several MVC components. From there, the framework takes over because you do not require additional coding. The app is easy to learn and get started: Getting up and running with AngularJS is perhaps the simplest thing a developer can imagine. Simply include some attributes into the HTML, and you can complete the first app in a couple of minutes. Data Binding in AngularJS is very easy: Can you remember trying to create a text property on a model that requires binding to your app UI? It is very difficult with most frameworks. That stress has been eliminated in AngularJS. In fact, you can see the ultimate results as you type in the span. Affordability: Because AngularJS is an open source framework, developers can come up with custom apps at lower costs. The main features of Angular 9: The main reason that AngularJS has gained a lot of popularity is its unique features. The features make app development easy and result very intuitive. These features include; Two-way data-binding: Data binding is one of the most notable AngularJS features. This feature helps save the developer from doing a lot of coding. In any app, 80% of the code base is dedicated to manipulating, traversing, and listening to DOM. However, data-binding in AngularJS helps to reduce the work so that the developer can concentrate with the app. Ready to use templates: The AngularJS is simply plain HTML. The browser parses these templates into the DOM and transforms it to AngularJS compiler. Then, the AngularJS Framework traverses the templates to get rendering instructions called directives. The ready to use templates make it easy even for people with little computing skills come-up with great apps. Dependency injection: This is an essential feature in AngularJS that makes the developer able to ask for dependencies as opposed to making them on his own. Think of this feature as a way of saying I need X and not starting to make X. Testing feature: The AngularJS developer team worked with special focus on testability in mind. This means that you can easily test AngularJS apps. AngularJS has started with version 1.0 and make so many positive changes when it comes to version 1.3 but there are some glitches regarding security in version 1 but when it comes with version 2.0 most of the problems are solved because in version 2.0 they have made so many good changes regarding security.AngularJS supports on fast and modern browsers such as chrome , Firefox , Opera , Internet Explorer 8 , Android , iOS6+ so we can work without any hesitation on AngularJS. It’s one of the most popular JavaScript framework by which you can implement the things what JSP and another most of the technologies front frameworks implements. Earlier days, the many frameworks were boom but When angular came into picture, it was a blast. As a developer I can surely say that in future any technologies having JavaScript as a base will not die. And recently AngularJS 2.0 is launched. This framework gives a lot of things easy and it has number of features you can get it from it’s official website. And the funny thing is that if you know JavaScript and Jquery  then there is no more efforts to learn the things. The most awesome things you will love Two Way Data Binding and MVC Architecture.   Job opportunities hiring for Angular 9 Developers : 1. Major reason behind this is the trend of Startups in India and majorly startups are ready to use new frameworks and AngularJS & React both are among the most used UI frameworks. 2. With Google backing Angular, it has evolved as an excellent framework for UI development. One with proper functional knowledge of the framework can do wonders and make an application scalable, faster with very less effort. 3. 2-Way Data Binding, Templates, Routing, SPA. All these make AngularJS stand strong against other frameworks.   Moral of the Story: It is worthy. In market there is high demand for the AngularJS but the knowledgeable developers are less as compare to demand. For Angular JS, Node JS Training, Visit www.docckolkata.com, Call 9433526196  

Ethical Hacking and what it is?

Ethical hacking , often performed by white hats or skilled computer experts, is the use of programming skills to determine vulnerabilities in computer systems. While the non-ethical hackeror black hat exploits these vulnerabilities for mischief, personal gain or other reasons, the ethical hacker evaluates them, points them out, and may suggest changes to systems that make them less likely to be penetrated by black hats. White hats can work in a variety of ways. Many companies utilize ethical hacking services from consultants or full-time employees to keep their systems and information as secure as possible.
The work of ethical hacking is still considered hacking because it uses knowledge of computer systems in an attempt to in some way penetrate them or crash them. This work is ethical because it is performed to increase the safety of the computer systems. It’s reasoned that if a white hat can somehow break the security protocols of a system, so can a black hat. Thus, the goal of ethical hacking is to determine how to break in or create mischief with the present programs running, but only at the request of the company that owns the system and specifically to prevent others from attacking it.
People enter the field of ethical hacking in a variety of ways. Many people are very computer savvy and many, but not all, have an educational background in computer science. In some instances, the white hat has gained his or her experience by first being a black hat.
If black hat hacking was at a sufficiently criminal level, the black hat turned white hat may have served jail time before resuming a career in a more productive and positive way as an ethical hacker. The computer world is peopled with former black hats, who now hold ethical hacking jobs. Conversely, some white hats, such as Steve Wozniak, never committed any illegal acts, but simply possess the know-how and skills to analyze problems with any computer system.
With increasing use of the Internet and concerns about its security, especially when it comes to things like consumer information or private medical details, there is considerable need for computer experts to work in ethical hacking. Even sites owned by organizations like the US government have been hacked in the past, and concern about information theft remains incredibly high. Designing impenetrable systems or identifying the current weaknesses of a system are vital parts of keeping the Internet safe and information private, and even with the present legion of ethical hackers that perform this work, there is still more work to do.
Those with interest in the field of ethical hacking often acquire a lot of their skills on their own, and many have particular talent with and affinity for computers. Some knowledge can also be acquired through formal education in computer programmingThis work requires creativity, and the ethical hacker must be able to think outside of the box, coming up with as many possible ways as he or she can derive, a system might be encroached upon by black hats.

Angular is a JavaScript-based open-source front-end web application framework . AngularJS is a toolset for building the framework most suited to your application development. AngularJS was originally developed in 2009 by Miško Hevery as the software behind an online JSON storage service, that would have been priced by the megabyte, for easy-to-make applications for the enterprise. This venture was located at the web domain “GetAngular.com”  and had a few subscribers, before the two decided to abandon the business idea and release Angular as an open-source library. It is fully extensible and works well with other libraries. Every feature can be modified or replaced to suit your unique development workflow and feature needs. HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop. Angular is a structural framework for dynamic web apps. With AngularJS, designers can use HTML as the template language and it allows for the extension of HTML’s syntax to convey the application’s components effortlessly. Angular makes much of the code you would otherwise have to write completely redundant. Some reasons why developers should know “Angular ”: Angular  supports single page applications. Angular provides all of the necessary infrastructure from routing (being able to take a URL and map it to dynamically loaded pages), templates, to journaling (deep linking and allowing users to use the built-in browser controls to navigate even though the pages are not refreshing). Angular  helps developers Manage Stage. It’s the “illusion” of state that was perpetuated by ASP.NET that confuses developers when they shift to MVC. I once read on a rather popular forum a self-proclaimed architect declare that MVC was an inferior approach to web design because he had to “build his own state management.” Angular  gives developers control. Angular enables a new scenario known as a “directive” that allows to create new HTML elements and attributes. In my emulator, a directive to create two new tags: a “console” tag that writes the console messages and a “display” tag that uses SVG to render the pixels for the emulator (OK, by this time if you’ve checked it out I realize it’s more like a simulator) is used. This gives developers their controls – and more importantly, control over the controls. Angular  enables a Design- Development workflow. The designer can add markup without completely breaking an application because it depends on a certain id or structure to locate an element and perform tasks. Instead, rearranging portions of code is as easy as moving elements around and the corresponding code that does the binding and filtering moves with it. Although I haven’t yet seen a savvy environment where the developers share a “design contract” with the UI/UX team. Angular  handles dependencies. Dependency injection is something Angular does quite well. Single Page Applications use dynamic loading to present a very “native application” feel from a web-based app. Contact DOCC Kolkata for details about Angular JS Training: 94335-26196.  
Taylor Otwell created Laravel as an attempt to provide a more advanced alternative to the CodeIgniter framework, which did not provide certain features such as built-in support for user authentication and authorization.

Web design started as a puzzle box emptied over a table with a lot of elements but no clue of what to do with those icons, boxes, which ones were the better colors to use, where did those icons had to be placed, what were the boxes for. First web designers had no idea about which one was the right way to go, however, things got better so now you can criticize all the effort and won battles during the last 20 years of web design. And well, they were able to design a website, 20 years ago, using only the initial browser experiments and lacking standards, styles, community and the PNG format ; ) (remember that GIF era), so, they deserve a huge and big thanks for bringing this web design . 1996 was the year that defined the beginning of a new era, and for many designers it was also a shameful period. Go no further, the first impression you have in a website might be sore eyes. What’s with the vibrant colors? websites with red, pink or yellow background can’t be watched for too long without compromising your eyes’ health. However, using a white background along with a few links and basic information is the correct way to start your site. Make it simple, there are tons of options besides Times New Roman or Courier New, the default system typos, and regarding color you can opt for more clever palettes instead of the dull black, blue and red interfaces. This stage also means abusive utilization of animated gifs that were supposed to make the website… fun and and interesting?, hehe the GIF era! This was also the era of the ‘Under Construction’ terror. People were not fully aware of how websites worked and therefore there was not a proper construction system established.interesting?, hehe the GIF era!
