IT, Cloud & Security Courses
Build and defend the systems everything else runs on - certifications, networks, cloud platforms, and the hardware underneath
Across this directory, few areas arrange themselves into a ladder. These five do, rather than forming a menu. Support, systems, networking and cloud are roughly the order a working career walks them, and the exams are the rungs an employer can see from the outside. The deciding question is therefore not which subject appeals most, but which rung you are standing on right now.
Elsewhere in this directory you pick the section that matches your curiosity. Here you pick the section that matches the job you could plausibly hold next. IT hiring is unusually literal: a posting names a platform, a tier of support or a credential, and the application matching that line is the one a human ever reads. That makes routing easier than in most fields, and it makes routing badly more expensive. The common mistake is jumping two rungs at once, almost always into security or cloud, because those are the categories with the interesting job titles. It works right up until something breaks, and then the missing layer underneath turns out to be the layer the incident lives in.
The ladder, bottom rung first
- IT Support & Administration is the entry rung, and it is badly underrated. Tickets, user accounts, password resets, Active Directory group membership, the printer that works for everyone except one person. This is where most IT careers begin, it is the quickest way in without a degree, and it teaches something no course does: what people do to systems.
- Systems & Hardware is what sits underneath the ticket. Operating systems, file systems, storage, boot order, and above all Linux at the command line, because a great deal of what you will eventually administer has no graphical interface at all. Skipping this rung is the most common reason a promising career stops moving once the work stops being procedural.
- Cybersecurity & Networking is how traffic moves and how it gets abused, and the order of those two words is the order to learn them. TCP/IP, routing, DNS, what a packet looks like in Wireshark, then the attacks that bend each of those. Security knowledge resting on a vague grasp of networking collapses at precisely the moment it is needed, because an incident is a networking question asked in a hurry.
- Cloud Computing is the same machines rented by the hour, in three dialects that do not transfer between employers. Azure suits an organisation already standardised on Microsoft, AWS carries the widest hiring, Google Cloud leans data-heavy. Pick the dialect in use where you work or where you want to work, and commit to it for twelve months. Choosing on a feature comparison is how people pay for an exam nobody near them is hiring for.
- IT Certifications is not a subject at all. It is a deadline. It holds the preparation courses for the exams the other four sections are measured by, and it is the right section only once you know which exam you are sitting and roughly when.
What a certificate buys
A vendor exam is not a degree and not an accredited qualification. What it buys is passage through a filter. A recruiter holding hundreds of applications and no way to assess any of them needs one unambiguous line to sort on, and the credential is that line. This is a real benefit and a narrow one. It proves you could answer questions about a system in a quiet room. It says nothing about whether you can repair that system while a floor of people wait for you, which is the whole of the job, and experienced interviewers know it perfectly well. That is why the conversation after the filter is always about what you have broken and put back together.
So the workable sequence is the reverse of the advertised one. Build a small thing you administer yourself, break it deliberately, repair it, and then sit the exam that certifies what you already understand. Every exam has its own page under certifications, carrying the vendor's own figures and renewal terms, each with its as-of date. If you are still choosing between ladders, the IT certifications page sets out how the cloud, security, networking and service-management tracks relate to each other. Then aim one rung below the job you want rather than at the job itself, because that is the rung people are hired onto.

Frequently asked
- I have never worked in IT. Which section is mine?
- IT Support & Administration, without hesitation. It assumes nothing, the entry-level roles it leads to exist, and the work itself is an education in how organisations fail. Everything above it on the ladder becomes far easier once you have spent time watching real systems misbehave in front of real users.
- Which cloud platform should I learn?
- Whatever your workplace has standardised on. Failing that, whatever recurs in the vacancies you send applications to. The three major providers cover much the same ground in three incompatible vocabularies. The ground travels with you when you move; the vocabulary does not, and neither do the local vacancies.
- Can I go straight into security and skip networking?
- You can start the courses. You will stall at the first real incident. Security is largely the study of how systems built to communicate are persuaded to communicate with the wrong party, and that sentence is unreadable unless you know how the communication works. Learn routing, DNS and packet capture first; it is the cheapest insurance in this category.
- Is a help desk job a dead end?
- Only if you let it become one. It is the best-paid classroom in IT: you meet every failure mode the organisation has, you learn which ones keep recurring, and you get to know the people who own the systems you want to move towards. The ones who stall are the ones who stop asking why a ticket happened once answering it became routine.
- Should I take the exam before or after I have the job?
- Before, if you need it to get past the filter and into the interview, which is the usual case for a first role. After, if you are already employed and the credential is there to formalise what you do daily. What rarely works is passing an exam for a platform you have never touched and expecting the interview to stop there.
Why Learn IT, Cloud & Security?
The infrastructure track: understand how computers, networks, and cloud platforms actually work, then prove it with the certifications hiring managers check. Courses range from first-job IT support and Linux administration to penetration testing, cloud architecture on AWS, Azure, and Google Cloud, and the exam preparation that turns experience into credentials.
