Cybersecurity, big data and software programming are the key sectors of the job market. Recruiters, faced with a real shortage of talent, offer particularly attractive salaries and working conditions for candidates and students in training… However, these areas of IT are complex and demanding. In particular, they require the mastery of numerous technical solutions. If you plan to work in one of these fields, here are 10 essential tools to set yourself apart and succeed in your career in IT!

1 – An IDE or integrated development environment

The IDE or integrated development environment is the indispensable ally of all developers. It takes the form of a software platform that brings together a set of programming tools in a single interface. IDEs simplify and speed up development times with smart features like autocompletion or debuggers that allow you to quickly test code.

There are a large number of IDEs because each of them is adapted to a technology or a programming language. The most popular are:

• Visual Studio;
• Eclipse;
• IntelliJ IDEA;
• Netbeans ;
• Aptana.

The majority of these development environments offer trial versions or student licenses. You can therefore install them and use them for your personal projects or simply to test the profession of developer!

2 – A source code manager

Source code management systems, also called versioning, are also essential in software development and big data. These tools make it possible to store and manage the code between several programmers.

Every change made is saved so that it can be retrieved by other team members. This history helps keep track of developments and promotes code reviews and continuous deliveries.

The most popular source code managers:

• GitLab;
• GitHub;
• AWS CodeCommit;
• Bit Bucket.

3 – Firewalls and antivirus

Firewalls and antivirus are not reserved for IT experts, but they are particularly essential for these professionals who are regularly called upon to work with sensitive data and applications. They are also essential tools for cybersecurity consultants.

They are generally used alongside other solutions such as managed detection services that detect more sophisticated cyberattacks and network protocol analyzers such as WireShark.

4 – Frameworks

The frameworks or frameworks in French bring together a set of tools and software components. They allow IT experts not to develop from scratch by taking advantage of pre-written features. They are essential in software programming as well as in data science and cybersecurity, because they speed up development times, facilitate maintenance and limit the risk of error.

The most popular frameworks are:

• TensorFlow;
• Pandas or PyTorch for data science;
• NIST for cybersecurity;
• Ionic to create responsive applications;
• React JS for the front-end;
• Node JS for the back-end;
• Symfony for the PHP language;
• PyCharm for Python;
• Xamarin and Flutter for mobile apps.

5 – Containerization solutions

Containerization solutions are among the most complex and advanced tools in programming. If you are just starting out or are in training, you may not have heard of it yet. However, containers are becoming essential in IT and mastering containerization tools is a sought-after skill!

In short, containers are standardized units that isolate an application from its environment. The code can thus run from any operating system. These containers also make it possible to create lighter and easily maintainable applications thanks to their modularity. The most popular containerization solutions are Docker and Kubernetes.

Docker is a platform that aims to accelerate the development and testing of multi-container applications. Kubernetes, on the other hand, is an open source solution that automates the operation of these containers. Want to know more about these tools? They are part of our DevOps & Cloud Master’s program!

6 – Database management systems (DBMS)

Databases (BDD) are the optimal solution for storing big data used in data science as well as all the information necessary for the operation of applications. These databases can be hosted internally, on servers located within companies, or externally in private data centers and in the cloud.

To communicate with these databases and modify, insert or delete information, IT professionals use graphical software: database management systems (DBMS). These tools allow:

• increase productivity by quickly providing the user with reliable data;
• secure data by controlling access;
• optimize storage and monitor system performance.
• The best known DBMSs in IT are MySQL, PostgreSQL, Oracle Database and Microsoft SQL Server. You can learn more about how this software works during our BTS SIO training, SLAM option.

7 – Data visualization tools

Data visualization tools are the allies of data miners, scientists and engineers. They make it possible to model raw and often heterogeneous information in more graphical and usable formats.

These solutions are therefore also widely used in development and cybersecurity, as they promote analysis, communication and collaboration between teams. The most popular modeling tools are:

• QlikQ which allows for example to generate PDFs and PowerPoint;
• Metabase for shareable graphics renderings;
• Power Bi which offers more than 20 types of visuals and customizable templates;
• Google data Studio which offers a large library of templates.

8 – Ticketing tools

Ticketing tools or ticket managers are not specific to IT, but they are nonetheless essential in this sector. They make it possible to react more quickly to incidents and bugs thanks to user alerts. They also promote collaboration between teams and automate workflows. Finally, these tools can be used to trace the events and interventions that have occurred on an application or a network.

The most popular ticketing software in the workplace are:

• Zendesk ;
• Monday.com;
• Freshdesk;
• ZohoDesk.

9 – Publisher certifications

Publisher certifications are not strictly speaking tools, but they play a fundamental role in the success of your career. These credentials are issued directly by major IT players such as AWS or by recognized organizations such as the CCC (Cloud Credential Council), an independent certification provider specializing in IT. They attest to a very advanced level in the discipline they concern and are sought after by IT professionals.

This includes:

• the CCC Big Data Foundation by EXIN certification;
• the certification of Opquast® “ Quality control in Web project ” ;
• Amazon Web Services (AWS) Cloud Practitioner certification.

10 – Digital learning tools

Online educational resources and digital learning tools are also not specific to IT. But in big data, cybersecurity and software development, continuous training is essential to stay abreast of the latest technologies, but also of vulnerabilities and flaws.

Access to online courses and training also helps IT specialists quickly acquire new skills, as their missions can be very versatile depending on the structure and the sector of activity in which they work.
