Cloud Computing and it’s benefits

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)

Will PHP exist in 2021?

You have to read it twice, it’s like will Life exist in 2020? Well, No one can tell you this.

But yes, you can look at the exisiting things as many websites, softwares are built using PHP only. It will totally depend upon the enhancements being made in the future.

As there are many other languages like Java, Python which is taking an edge over PHP nowadays, but we can never say that PHP is less.

As many people and organisations still work on PHP because they find this language as a proper fit for their projects.

Even C++ was developed back in 80s, but still it’s one of the strongest languages. So, one can never answer this question. If you are having interest in PHP and want to learn its basics, then go with it without a second thought.

Remember, Language is a secondary thing, primary are your Logics.

JavaScript frameworks for quick software development:  

 

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.

Angular 9 IS worth learning?

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.

Career Prospects In PHP Programming at present day

PHP is a scripting language used predominantly for web programming. It is very popular mainly because it is open-source and you don’t have to buy a license or copy to install it on your computer, and the websites created using it are very dynamic and attractive. The PHP community is very active and solutions for any technical problem can be found online, either on websites, blogs or forums. According to a Netcraft survey, more than 100,000,000 hostnames have PHP coding and it is installed on more than 20 million websites and one million web servers. Popular websites such as WordPress use PHP as their publishing tools.

How long will it take for me to learn PHP? Do I have to take a course?

To learn PHP, it is very important to learn C and C++ since most of its run time code is made of C libraries and it is also scripted in C. PHP is very easy to learn – it is a straight-forward language and does not have many complexities. When I was doing my under graduation in Computer Applications, a basic PHP course was offered to us as part of extra credits. We all could write a simple, functional script in a matter of minutes. There are dozens of websites that provide free step-by-step guides to learn PHP so much so that you can become a master of the language just by self-study. A living example is my dad who, at age 70, is trying to learn PHP to improve the functionality of his website on temples which is his retirement hobby. He was able to succeed just by reading online tutorials. If a 70-year-old can do it, I am sure you can too!!

What do recruiters look for in PHP programmers?

PHP programmers who are skilled in languages like C, C++ and Java, and also keep abreast of the latest developments in mobile and wireless technologies, are in great demand. A Bachelor’s degree in Computer Science or Computer Applications is a necessary criterion to join most companies as a PHP programmer.

PHP vs Java: Which is the Code for Developing a Bright Future?

Are you  thinking about really getting to know the ins and outs of a web development language, trying to decide between PHP and Java? While comprehensive web programming knowledge will serve you well, many developers become specialists, and their expertise can go a long way toward securing work, particularly with development teams.

But you might be trying to figure out which language will give you the best long-term return on your learning investment. What will best support the intricate development needs of large companies?  Which will help startups and small businesses get the most bang for their limited bucks? And ultimately, which will be in the greatest demand?

Both PHP and Java are pervasive and integral to the modern web. And since they can be used to accomplish some of the same tasks, possibly no two languages prompt as much debate over relative strengths and weaknesses. Both have serious credentials, supporting some of the world’s largest and most profitable sites. And this likely means that both will have a long and promising future in web development.

So how do you choose?  Well, if you haven’t already, you might start with a comprehesive survey course in web development to get a good overview of how the languages work within a larger context. But as you begin to explore these languages, here are some ideas about them and their differences, drawing from the experience of developers who use them regularly.

One of the primary structural differences between PHP and Java is the difference between strongly- and weakly-typed languages. Java is a strongly-typed language, meaning it requires explicit statements of intent to function and that it is backed by a compiler. At the highest level, you can think of this as meaning it has strict expectations on how you express inputs and outputs. If these exact expectations are not met, the compiler will fail and the program will not work until errors are resolved.

PHP, in contrast, is weakly typed, essentially meaning it is more flexible and reliant on “common sense programming” in how a task is accomplished.  While this may sound more attractive because it requires less formal knowledge, some contend that it complicates certain tasks, particularly in object oriented programming, with its lack of standards.

Ultimately, these characteristics imply that java can be a good choice when development is complicated and relies on teams of professional developers. Rather than making work more challenging, the precisely defined standards allow for easier understanding and greater efficiency among teams. On the other hand, PHP is more accessible to inexperienced programmers. If a web product intends to allow users to work with the code (such as web and blog creation software or small business sites) PHP can fit the bill nicely. It can also be a nice economical and nimble choice for small teams using agreed coding standards and when dealing with simple functions.

You have likely taken away, thus far, that PHP can be characterized as fast, flexible, and free.  Unless, of course, it leads to jam-ups caused by a lack of coding standards, this is a fair statement. And there a few other facts about PHP that further define these traits.

First, an advantage of PHP is that, aside from being free in terms of coding standards, it is free of cost. The open-source language is available on virtually every Web-hosting platform for anyone to use.  It is the programming language of the people!

Then, to further define PHP’s flexibility is the fact that it works universally, across platforms. The reason for this is that the code is processed entirely on the server side and delivered as dynamic content to the viewer. For large scale operations that need to work on every system architecture, PHP can be the way to go.  It can provide an easy method to ensure people are seeing what they should, wherever they are.

Graphic Design vs. Web Design: Which Career is Right for You?

Are you naturally creative? Do you have a knack for thinking outside the box? Do your friends often come to you for tips on color palettes or accessorizing outfits?

If so, working in the design industry may be one way to turn your imagination and originality into a career. Because what could be better than earning a paycheck for something you’re already passionate about?

There are many specialties that fall under the umbrella of the design industry. For example, a fashion designer is different from  a  textile designer, which are both very different from an interior designer.

While they all share similarities, there are distinct differences in these fields. Understanding these distinctions is an important part of determining what type of career you’d like to pursue.

If you’re looking for an opportunity to combine your love of technology with your passion for design, you’ll probably find yourself faced with a tough choice: GRAPHIC DESIGN  versus WEB DESIGN.

It’s important to have a comprehensive understanding of each field in order to determine which best suits you and your personality. Conducting a little extra research now can help prepare you for success in the long run.

We created an infographic that outlines these two common—and commonly misunderstood—career paths.

Opinions from the experts …

Although aspects like job growth and salary potential are definitely important, they shouldn’t be the determining factors in your quest for the perfect career. After all, if you’re going to be investing 40-plus hours per week into this job, you might as well enjoy what you’re doing, right?

We got in touch with some professionals in both fields to hear their thoughts on the debate over graphic design versus web design. These thoughts came straight from industry experts, so consider them insider perspectives.

After gathering their thoughts, we broke them down into bite-sized chunks to make them easy to digest. These tidbits should help give you a better idea of which career suits you best.

Graphic designers …

1)Put the art first

2)Have a one-way relationship with their audience

3)More artistic (i.e., sketch with a pen and paper)

4)Emphasize visual theory in their designs

5)Must focus on how a design communicates a message to its audience

6)Need to know how each element of a design translates to print

7)Have one shot to get a design right once it’s printed

Web designers …

1)See the art as a way to leverage technology

2)Have a mutual interaction with their audience

3)More technical (i.e., coding and programming)

4)Employ an engineering approach to their designs

5)Must predict how a design will make its audience feel and react

6)Need to know how to design for versatile mediums (i.e, laptop, tablet, smartphone)

7)Can develop and enhance their work over time
So after comparing graphic design versus web design on multiple levels, you should be able to confidently determine the field in which you’ll excel. Once you decide which creative path you’re interested in traveling, take a moment to learn more about the education that can jumpstart your journey.
