The document discusses key concepts in software development, including version control systems (VCS), containerization, and low-code development. It explains VCS as tools for managing file revisions with benefits like history tracking and collaboration, while containerization allows application management in isolated environments. Low-code development is presented as a method that accelerates application creation through user-friendly components and templates.

Version Control Systems

4. Version Control Systems… What
are they?
• A version control system (VCS) is a system that
facilitates the management of multiple revisions
of the same unit of information
• It records changes to a file or set of files over
time so that you can recall specific versions later
• This can apply to various types of items, such as
documents, source files, or other similar items

5. Benefits of them… i.e. vcs
•History Tracking
•Collaboration
•Code Backup and Recovery

6. Categories of VCS
•Centralized Version Control Systems
(CVCS)
•Distributed Version Control Systems (DVCS)

7. Centralized VCS
• In CVCS, there is a central server that stores the
entire history and versions of files.
• Developers check out files from the central
repository to work on them and then check them
back in when done.
• Provides centralized control and history tracking.
e.g.: CVS (Concurrent
Versions System), Subversion
(SVN)

8. Distributed VCS
• In DVCS, each developer
maintains a local copy (clone)
of the entire repository,
including the complete history.
• Developers can work offline
and have more flexibility in
branching and merging.
e.g.: Git, Mercurial, Bazaar

9. Containerization
Never install
locally

10. Containerization… what is that?
• Containerization is a method of packaging,
distributing, and managing applications and their
dependencies in a consistent, isolated
environment called a container that can be run on
any infrastructure.
• This makes it easy to deploy and scale
applications, and it also helps to ensure that
applications are consistent across different

11. Advantages of containerization
• Consistent
• Isolated
• Portable
• Resource Efficient
• Scalable

12. containers vs Virtual machines
• A virtual machine (VM) is like a copy of an actual
physical computer. A virtual server operates in a multi-
tenant environment, meaning that multiple VMs run on
the same physical hardware.
• Containers sit on top of a physical server and its host
OS. Every container shares the host OS kernel and the
binaries and libraries to run the required application.
• Containers and VMs are not mutually exclusive and can

14. Container Engines…
• Container Creation
• Container Isolation
• Resource Management
• Networking: Container
• Storage Management
• Lifecycle Management
• Image Management
• Security

15. Container Engines…
• Docker
• Podman
• LXC (Linux Containers)
• containerd

16. Low Code Development

17. What is Low code development?
• Software development approach that aims to simplify
and accelerate the process of creating applications.
• It replaces the need to create custom
code with a collection of ready-to-go
components, boilerplate scripts and
integrations, solution blueprints, visual
workflow automation tools, and other
user-friendly features.

18. Benefits of low code…
• Faster Development
• Reduced Coding Complexity
• Increased Collaboration
• Enhanced Agility

19. Low-code vs no-code
Development
• Definition
• Target Audience
• Complexity
• Customization

20. Low Code Platforms…
• OutSystems
• Microsoft Power Apps
• Kissflow
• Quickbase
• Salesforce Inc
