A microservices architecture structures an application as a set of small, independently deployable services, each owning one capability and its data. It trades operational complexity for independent scaling, deployment, and team ownership.
Microservices - Interview Concepts - ExtraBrain is part of ExtraBrain's local-first Mac workflow for live interviews, meetings, transcription, provider control, and responsible AI use.
A microservices architecture structures an application as a set of small, independently deployable services, each owning one capability and its data. It trades operational complexity for independent scaling, deployment, and team ownership.
ExtraBrain has 1 current public platform family, macOS, with support for 2 Mac CPU families: Apple Silicon and Intel.
ExtraBrain has 3 configurable data paths to review before sensitive work: local Parakeet transcription, local Gemma 4 where installed and compatible, and external providers you choose.
Each service owns its data and can be built, deployed, and scaled on its own.
Services talk over synchronous APIs or asynchronous messages, often behind an API gateway.
Independence improves scale and team velocity but adds network, consistency, and operational complexity.
Use any live AI assistant only where interview, workplace, school, and platform rules allow it. Do not use generated answers to misrepresent your skills, experience, or authorship.
Short answers for people and crawlers comparing ExtraBrain with other live AI assistants.
When independent scaling, team autonomy, and fault isolation outweigh the added operational and consistency complexity.
Through synchronous REST or gRPC calls and asynchronous messaging via queues or event streams.
