Backend is a part of a website or software that is unavailable to users, meaning that it is about server-side functionality. So backend developers work with architecture, databases, APIs, scripting, and web servers. The visual part of the page like fonts, interface designs, colors is frontend development. Content of the page like images, text, videos, and everything triggered by the user’s actions is backend development.
Backend developers have to know these technologies:
- at least one web development language (Java, Python, Ruby, .NET)
- databases (MySQL, MongoDB, Oracle, SQLServer)
- caching mechanisms (varnish, Memcached, Redis)
- servers (Apache, Nginx, IIS servers)
- APIs
- frameworks of chosen web development language
- security tools
Backend developers deal with finding solutions for the website’s goals, data storage, payment processing, architecture, the logic of the system, interoperability, etc. Backend developers also work closely with front-end developers to connect the server’s and client’s side properly.
Backend is a vital part of any website or application since they will simply not work without it. The beauty and functionality of your interface design will not matter if the page is not loading or shows content in a weird way.
