What is a technology stack? It’s a question that can be difficult to answer, as the definition can vary depending on who you ask.

Generally speaking, a technology stack refers to the various services, tools, and programming languages that are used to create and maintain a website or app.

Each application is made up of multiple elements, each with its own set of requirements. This is where developers use technology stacks to manage every part of the application and make sure everything runs smoothly.

However, since companies can have vastly different tech stacks, these come in many flavors. What’s the difference between each tech stack, and what should you know about them before using them? We’ll take a closer look at what technology stacks are and some of the most popular tech stacks used today.

Technology Stack

As a technical recruiter, I often hear job descriptions that list requirements like “3 years of experience with React” or “familiarity with the MEAN stack”.

But What Exactly is a Tech Stack?

A technology stack, also known as a solution stack or software stack, is a collection of various software components that work together to create a complete software solution.

Each element in the stack works with the others to perform a specific task that contributes to the overall functionality of the application.

For example, a common web development stack includes an operating system, web server, database, programming language, and framework.

Stacks can also be composed of different levels, with each level representing a different layer in the application. For example, the LAMP stack (Linux, Apache, MySQL, PHP) is a common open-source web development stack that runs on a Linux operating system.

The components of the LAMP stack work together to create dynamic web applications.

Most tech stacks will include a mix of open-source and commercial software, depending on the needs of the application.

Types of Technology Stacks

There are two main types of technology stacks: front-end and back-end.

Front-End: The front-end is what the user sees and interacts with. It includes the user interface and experience, as well as the client-side logic. The front-end is usually built with HTML, CSS, and JavaScript.

Back-End: The back-end is what powers the functionality of the application. It includes the server, application, and database. The back-end is usually built with a back-end programming language like PHP, Ruby on Rails, or Node.js.

Full-Stack: A full-stack technology stack includes both the front-end and back-end components. Full-stack developers are usually proficient in multiple programming languages and frameworks, making them well-suited to build complex applications from start to finish.

What is a Tech Stack Used For?

Technology stacks are used to create and power web applications. They provide a structure for developers to build applications with all the necessary components, and they can be customized to fit the specific needs of the application.

For example, a website that sells products online will need a tech stack that includes a way to track inventory, process payments, and ship orders.

A social media application will need a tech stack that includes a way to store user data, display content, and handle notifications.

The possibilities are endless, and the right tech stack will depend on the specific needs of the application.

Some common use cases for technology stacks include:

• Web applications
• Mobile applications
• Custom software
• Data analysis

What Should You Know Before Using a Tech Stack?

When choosing a tech stack for your application, there are a few things to keep in mind.

First, you’ll want to make sure that the tech stack you choose is well-suited for the type of application you’re building.

• For example, if you’re building a mobile app, you’ll want to make sure that the tech stack you choose includes a way to build a native mobile app.
• If you’re building a web application, you’ll want to make sure that the tech stack you choose includes a way to create a responsive web design.

Second, you’ll want to make sure that the tech stack you choose is well-suited for your development team.

• For example, if your team is most familiar with PHP, you’ll want to make sure that the tech stack you choose includes PHP.
• If your team is most familiar with JavaScript, you’ll want to make sure that the tech stack you choose includes a way to use JavaScript.

Third, you’ll want to make sure that the tech stack you choose is well-suited to your budget.

• For example, if you’re on a tight budget, you’ll want to make sure that the tech stack you choose includes open-source software.
• If you’re not on a tight budget, you’ll want to make sure that the tech stack you choose includes commercial software.

Fourth, you’ll want to make sure that the tech stack you choose is well-suited for your application’s needs.

• For example, if your application needs to be scalable, you’ll want to make sure that the tech stack you choose includes a way to scale.
• If your application needs to be secure, you’ll want to make sure that the tech stack you choose includes a way to secure it.

Popular Technology Stacks

Now that we’ve gone over what technology stacks are and the different types of stacks, let’s take a look at some of the most popular tech stacks used today.

MEAN Stack: The MEAN stack is a full-stack JavaScript stack that includes MongoDB, Express.js, AngularJS, and Node.js.

MERN Stack: The MERN stack is a full-stack JavaScript stack that includes MongoDB, Express.js, React, and Node.js.

LAMP Stack: The LAMP stack is a popular open-source web development stack that includes Linux, Apache, MySQL, and PHP.

Python Django Stack: The Python Django stack is a full-stack web development stack that includes the Django web framework, Python programming language, and PostgreSQL database.

Ruby on Rails Stack: The Ruby on Rails stack is a full-stack web development stack that includes the Ruby on Rails web framework, Ruby programming language, and SQLite database.

Choosing the Right Technology Stack

Now that you know what technology stacks are and some of the most popular tech stacks used today, how do you choose the right one for your project?

The best way to choose a technology stack is to first identify the goals of your project and what you need to build it. Once you know what you need, you can then research which programming languages, tools, services, and frameworks will best help you achieve your goals.

Keep in mind that there is no one-size-fits-all solution when it comes to technology stacks. The right stack for your project will depend on your specific needs and goals. However, by doing your research and taking the time to choose the right stack, you can set your project up for success.

The Bottom Line

If you are recruiting a developer, you should be familiar with what a tech stack is. A tech stack includes all of the software and technologies that are used to create a web or mobile application.

By understanding this, you should be able to ask developers the right questions during an interview and get a better sense of their skillset.
