The success of web applications development depends on many things, but first and foremost, on the right choice of the technology stack. It is what will help the company to make a profit or suffer loss. It is especially important for small companies that can’t risk resources. Technology stack is the core of every web application.
Let’s consider what falls within this concept.
It should be kept in mind that web application consists of two parts: client and server sides. The first one is what the user interacts with; it is front end, or a web app interface. The server side, aka back end, is never seen by the user and includes the code, databases, and servers.
Front end tech stack is composed of several technologies:
There are a lot of programming languages with different frameworks for fast and convenient coding which help to create the back end of a web application or web site. It is very important to choose an appropriate one.
Here are the most popular programming languages and frameworks:
Databases are needed to keep the web application data. There are relational and non-relational types of databases. The relational database organizes data as a chart with columns and rows. Non-relational databases do not have rows and columns and suit a particular kind of data. For example, data can be stored as a JSON document, pairs of key and value, or a graph with nodes and edges.
There are 3 most known databases:
The caching system relieves the load of the database and allows for working with huge web application traffic. The most popular of them are Memcached and Redis.
The server allows for the processing of requests from clients’ computers. Developers can choose Apache HTTP Server or Nginx.
The combination of these interrelated technologies, front end, and back end tools, is named the technology stack.
At the stage of the technology stack choice, companies can make some mistakes. The common ones are related to deciding based on these things:
It is important to be informed of competitors’ strategy, but there is no guarantee that their technology stack will be good and actual for your goals. Every project has its features, and it is unique.
Personal Preferences can be the argument only for highly-qualified technical specialists with huge experience and knowledge. In a different case, it is the wrong way.
Technologies do not stand still, constantly changing and updating. That’s why your previous technology stack can be out of date and useless for a new project, not to mention that projects are different.
A lot of information from different sources can lead to confusion. Without technical experience, it is very difficult to check arguments and consider all the pros and cons. It is about practice, not theoretical knowledge.
There are several valuable criteria which web development specialists keep in mind while choosing a technology stack.
Technology stack is directly related to the type of web application because different types have specific goals and need special tools. Clients need to decide exactly what web application they want.
There are three types of the web application complexity.
After the type of the web application is found, it is needed to take into account its business goals. Answer the question, what is more important for the web application, heavy load processing or high speed of loading?
Time is a very important resource in the business where the market is highly competitive. The faster the web application is ready, the sooner it will begin to generate revenue. Also, development costs depend on time too.
There are 5 time-related points, which you should keep in mind while choosing a technology stack.
This moment depends on two rates, which are different in each technology stack and should be foreseen.
Developer salaries. There is nothing new that specialists who work with different programming languages have a different salary. Pay your attention that more advanced technology will cost more.
Cost of maintenance. You should remember about the maintenance and updating of the web application after launch. Free open-source technologies help save money, such frameworks can be used and updated at any time with no restrictions.
It is very important to create a secure web application. The risk of a cyber attack which leads to financial losses is increasing every year.
There is no secure programing language, but development technologies have their security recommendations. You should follow them to minimize vulnerabilities and prevent threats to data security. You need to check that your web application meets the security guidelines before launch.
Scalability is the expected result of the successful project, you should foresee in advance possible variations of the development. There are two types of scalability:
Horizontal scalability. It means that a web application can maintain high performance when the number of users and proceeded requests increases.
Vertical scalability involves the opportunity to add new components into a web application without loss of performance.
Think over possible scenarios of web application development and choose the needed technology stack.
Let’s consider what technology stacks are used in the most popular web applications.
Choosing an appropriate technology stack for a web application is a challenging task and requires attention to many nuances. It takes the knowledge of the front end and back end tools and how well they suit particular goals. It makes sense to entrust this choice to specialists with extensive experience in software development. They will help you select the best technologies based on your functional and nonfunctional requirements.
