Glossary

Explanations of technical terms commonly used in system development.

API (Application Programming Interface)

A mechanism for exchanging data and functions between software. Enables integration between different systems.

API (Application Programming Interface)

An architecture that divides large applications into small, independently developable and deployable services. Improves scalability and maintainability.

Containerization

A technology that packages applications and their dependencies into a single unit. Docker is the most common example. Prevents issues caused by environment differences.

Scalability

The ability to expand processing capacity in response to increasing system load. Auto-scaling is available in cloud environments.

Microservices

A web application that dynamically updates content without page transitions. Delivers a fast, native app-like user experience.

An architecture that divides large applications into small, independently developable and deployable services. Improves scalability and maintainability.

MVP (Minimum Viable Product)

A product with the minimum necessary features. Shortens time to market and enables early user feedback.

Infrastructure as Code

A methodology for managing infrastructure configuration through code. Uses tools like Terraform to achieve reproducibility and automation.

CI/CD

A culture and methodology that integrates Development and Operations. Accelerates release cycles through automation and collaboration.

FAQ

QHow long does development take?

Timelines vary by project scale, but a simple web app takes 1-2 months, and a mid-scale business system takes 3-6 months. We can also prioritize MVP (minimum viable product) development for early release.

QHow long does development take?

Yes, since we employ agile development methodologies, we can flexibly accommodate specification changes during development. Through regular reviews, we adjust requirements and re-prioritize as needed.
