Instructor-led IT courses across web, mobile, data, design and more.
Most organisations already run CI/CD, but the pipelines are often written by each team on its own, with no shared standard, no clear code quality criteria and security scans that run only some of the time, while production deployments still depend on a…
Containers are now the standard way to ship software, from the developer's laptop and the CI/CD pipeline to Kubernetes in production. Yet many teams still use Docker only to the point where things run. Images end up large, builds are slow, vulnerabilities…
Development teams are expected to ship software faster and more often, so full-stack developers are no longer responsible only for writing code. They need to understand how their code is built, tested and deployed to Kubernetes. The usual problems are code…
As organisations expose more APIs to internal systems, mobile apps and external partners, each service tends to re-implement authentication, rate limiting, logging and data transformation on its own. Standards drift apart and security becomes hard to control.…
Many software teams still run into the same problems: overwritten code, lost files, no clear record of who changed what, merges that break the build and a commit history too messy to audit, because members only know basic Git commands without understanding…
As systems grow to many services, IT operations and service desk teams run into the same problems. One fault sets off dozens of alerts at once, tickets arrive without the right category, the same issue gets solved again because nobody can find the last fix,…
Getting a chatbot or RAG system to answer well on a developer's laptop does not take long. Keeping it answering well, consistently, in production is another matter. A small prompt edit quietly makes some answers worse, a model upgrade multiplies the bill, and…
Development teams now ship code to production several times a day with CI/CD, yet much of the security work still waits for a final check just before release. Vulnerabilities are found late, when they are hard and expensive to fix, or they slip into…
Once an organization runs dozens of servers, configuring each one by hand wastes time, creates inconsistency between machines and leaves no audit trail. Ansible solves this by describing the desired state of machines in YAML and bringing every server into…
When a system fails or slows down, the first question is how you find out and how fast. Many organizations still learn about problems from customer calls rather than from their own monitoring. Prometheus and Grafana are the open-source standard that DevOps…
Building and changing infrastructure by hand through a web console creates inconsistency, leaves no audit trail and makes it hard to reproduce an environment. Terraform solves this by expressing infrastructure as code that lives in Git, is reviewed through…
