What skills you needed to become a back-end web developer

 Definition

A Back-end developer is responsible for building the backend services that allow users to interact with applications. These services may serve data over HTTP/HTTPS protocols, implement security policies and controls, manage database connectivity (ODBC), and provide access to application functionality via APIs. 

The backend of a website is a variety of servers, applications, and databases. Code authored by backend developers allows browsers to convey with the databases and store data into the database, read data from the database, edit the data and delete the data or details from the database.

Web development is specifically divided into two parts- frontend and backend. The front end is all that the user sees i.e. the visuals and the designs. And the backend is all sense that makes things occur. Remember the first example that we experienced the scaler website, all the roles you did like adding data and pushing the button were accomplished on the frontend side, while whatever happened behind the settings like collecting the data, processing it, encrypting it, adding that form data to the database was done on the backend side.

Back-End Developer Skills

 Database Management Systems (DBMS)

 A database management system (DBMS) is software designed to store information and retrieve it efficiently. A DBMS stores information in tables and provides tools for organizing, searching, and retrieving data. A DBMS contains four basic components: storage, indexing, retrieval, and security.

To be a back-end web developer you should know how to control databases? All the data that is entered by the use are programmer stored in databases, you should build a secure database.

 Web Servers

 Web servers host websites and provide them with the services necessary to display content to users. Web servers are the heart of the internet. They communicate with clients, accept requests, and respond to those requests with the appropriate content. There are two types of web servers: static and dynamic. Static web servers generate pages based on files stored locally on disk. Dynamic web servers generate pages dynamically based on requests sent from browsers.

 Application Programming Interface (API)

 An API is a set of rules or protocols for accessing functionality provided by a computer program. APIs allow programs written in different programming languages to interact with each other. An API is similar to a library in that it consists of a collection of routines that programmers use to access functionality provided by a particular program.

 Content Delivery Network (CDN)

 Content delivery networks (CDNs) improve performance, reliability, and user experience by delivering content closer to end users. CDNs cache copies of popular content on their own servers across the Internet. When a content request comes in, the CDN delivers the cached version rather than requesting the original copy from the origin server. By doing this, the CDN reduces bandwidth usage and increases speed.

 Browser

 Browsers are applications that let people view, navigate, and interact with webpages on the World Wide Web. Browsers are often categorized by the operating systems they run on. Examples of browsers include Microsoft Edge, Chrome, Firefox, Safari, Opera, and Internet Explorer.

 Cloud Computing

 Cloud computing is a model of service provision where shared resources, software, and information are provided to computers and other devices over a network, such as the Internet. In cloud computing environments, consumers demand high levels of performance and flexibility while businesses need to cost-effectively manage their resources.

Average salaries

As a BACKEND DEVELOPER, you are likely to earn $120,798 per year.

In the UK, the salary range is £40,000 – £70,000

Best languages for a back-end developer

Back-End Languages

1. JavaScript 

 JavaScript is the language of the web and runs on top of most browsers. It's not mandatory to learn JavaScript if you're just learning HTML and CSS but it certainly makes sense to know both. You'll need JavaScript knowledge to build any website that includes a user interface (UI). You might have heard that JavaScript is outdated and doesn't work well anymore. That's false! In fact, some of the best programming jobs out there require deep experience with JavaScript.

 2. Python 

 Python is a general-purpose high-level scripting language. It's easy to pick up and has many useful features that make it ideal for automation tasks. A python is a great tool for data analysis and machine learning. If you want to automate things in the browser, you'll probably want to use Node.js. But if you want to script the backend then Python is almost always the right choice.

 3. PHP 

 PHP was initially created as a CGI (Common Gateway Interface) language. This means that it first ran on the server side before sending the request to the client side. Today, PHP is still widely used for developing dynamic websites. On the back end, PHP is mainly used to connect to databases.

 4. Ruby 

 Ruby is similar to Perl and Python. Like them, Ruby is built around basic concepts. Ruby syntax is concise and clean and uses indentation instead of curly braces to delimit code blocks. Ruby is suitable for prototyping while being quick to write. As a bonus, Ruby has a lot of libraries that make it even easier.

 5. Go 

 Go is a modern compiled language that compiles programs down to native binaries. These binaries can run across different platforms. Because of its simplicity, Go can be used for low-level systems programming, especially on embedded devices. While Go does lack an advanced type system compared to Java, it has a powerful package management system called to go get.

 6. C++ 

 C++ is a multi-paradigm programming language that supports procedural, object-oriented, generic, and, functional paradigms. Originally designed as a fast and efficient language for writing operating systems software, C++ has since grown to become the most popular and versatile language for programming today. Many major companies use C++ for their core products, including Google, Apple, Microsoft, Facebook, Amazon, Twitter, and Mozilla Firefox.

Conclusion

Even though backend developers work 'after the scenes, their assistance to a web application's success is powerful. To provide a functional and analytical social network, website, app, marketplace, etc. the developer must demonstrate good communication with all the web development team members, from the UX/UI designers to the frontend developers. Moreover, understanding the clients' and stakeholders' needs and wants can help create a successful system architecture and provide valuable solutions.
