A programming language is a formal language or a vocabulary and set of grammatical rules for instructing a computer to perform specific tasks. The term programming language generally refers to high-level languages, such as BASIC, C, C++, Java, COBOL, Ada, FORTRAN, and Pascal.
To answer the question- what programming language does amazon use we need to get into details. Most programming languages are textual; they use sequences of text comprising of words, numbers, and punctuation, much like written natural languages. On the other hand, there are some programming languages which are more graphical in nature, using visual relationships between symbols to specify a program.
Thousands of programming languages have been created, and many more are being created every year. Some languages are more suitable for solving different problems, which can make the decision process more straightforward. You will need to take into account the problems you need to address as well as your business case and type of customers.
Many programming languages are out there in market. Each language changes with syntax, complexity, feature, behavior but always remember their core remains same. While learning the first programming language it is relatively difficult to learn syntax, understand the meaning, to solve error, proper compilation. While taking the decision of choosing the correct language and to iterate the quickest following points need to be taken into consideration:
Amazon is an American multinational company. It focuses on e-commerce, digital streaming, cloud computing, and artificial intelligence. It is considered amongst one of the Big Four tech companies. Amazon initially started as an online marketplace for books but later expanded to sell electronics, software, video games, apparel, furniture etc.
Amazon now has several types of distribution facilities which comprise of cross dock centers, fulfillment centers, delivery stations, sortation centers, Prime now hubs, and Prime air hubs.
Java is a general-purpose programming language. It is class-based and designed to have as few implementation dependencies as possible. Java code can run on all the platforms that support Java without any need for recompilation. The syntax of Java computing language is similar to C and C++, but has fewer low-level facilities than either of them.
As of 2019, Java was one of the most popular programming languages in use as per GitHub, particularly for client-server web applications, with a reported 9 million developers. Over 45.5 percent of professional developers favor Java according to Stack Overflow’s 2018 survey. Java can also be very resource-intensive, as compared to other language.
With the Android market share larger than all of its rivals combined in the smartphone operating system space, this is one of the main incentives for using Java. Java’s ability to simplify application development and to deploy it across various operating systems has made Java the language of choice for larger organizations.
C++ is a general-purpose programming language which is an extension of the C programming language, or "C with Classes". The language has expanded significantly over time, and modern C++ has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. It is usually implemented as a compiled language. C++ is a very modern, object-oriented version of C.
C++ is the language used for any application where the performance matters most. For instance, companies, especially in the financial sector, use it for their backend systems. C++ is adopted both for boring and for most exciting areas of technology. Due to its reputation for working at high speed, C++ is the preferred language for graphically intensive applications as well, including game development, graphics engines, and virtual and augmented reality.
Perl is a high-level, general-purpose, dynamic programming language. Most of the main website application code is in Perl using something called Mason which basically let you interpolate Perl and HTML the way you can with PHP.
Amazon is apparently able to do what it needs to do using on board existing programming languages. This is a perfectly valid business decision. Amazon unlike many others likes to build and use its own tools. Amazon aggregates massive computers, storage, and networking gear that is customers share in what is called a public cloud.
