Cloud Migration

Cloud migration is the process of moving applications, data, and IT infrastructure from on-premise servers to cloud platforms like AWS, Azure, or Google Cloud. It includes assessment, planning, execution, and post-migration optimization.

Penetration Testing

Penetration testing (pen testing) is an authorized simulated cyberattack on a computer system to evaluate its security. Ethical hackers attempt to exploit vulnerabilities to identify weaknesses before malicious actors can.

SaaS (Software as a Service)

SaaS is a software delivery model where applications are hosted in the cloud and accessed via the internet on a subscription basis. Examples include CRM platforms, project management tools, and accounting software.

DevOps

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the development lifecycle and deliver high-quality software continuously. It involves CI/CD pipelines, automation, and monitoring.

Digital Transformation

Digital transformation is the integration of digital technology into all areas of a business, fundamentally changing how it operates and delivers value to customers. It includes modernizing workflows, adopting cloud infrastructure, and leveraging data analytics.

SIEM (Security Information and Event Management)

SIEM is a cybersecurity solution that collects and analyzes security data from across an organization's IT infrastructure in real time. It helps detect threats, manage incidents, and meet compliance requirements.

CI/CD (Continuous Integration / Continuous Delivery)

CI/CD is a development practice where code changes are automatically built, tested, and deployed. Continuous Integration merges code frequently, while Continuous Delivery automates the release process to production environments.

Infrastructure as Code (IaC)

Infrastructure as Code is the practice of managing and provisioning IT infrastructure through machine-readable configuration files rather than manual processes. Tools like Terraform and Ansible enable repeatable, version-controlled infrastructure deployments.

API (Application Programming Interface)

An API is a set of protocols and tools that allows different software applications to communicate with each other. APIs enable integrations between systems — for example, connecting a payment gateway to an e-commerce platform.

CTO-as-a-Service

CTO-as-a-Service is a model where businesses hire fractional or part-time Chief Technology Officers to provide strategic technology leadership without the cost of a full-time executive. It includes technology roadmap planning, vendor selection, and team guidance.
