Software Architecture

Software architecture is the structure of a system: which parts it has, how they connect, and where the decisions that are expensive to undo were made. It sets the cost, reliability and speed of everything built on top of it.

What it covers

• System structure: how software is split into components, services or modules, and what each part is allowed to do.
• Integration points: how the system talks to databases, other services and external providers.
• Non-functional decisions: where performance, availability, security and data storage requirements are built in.

Why it matters to the business

• Cost trajectory: architecture determines how fast running and maintaining the system costs increase.
• Team speed: a clear structure lets several teams work in parallel. A fuzzy one serializes everyone.
• Exit options: systems coupled to one vendor or one platform become harder to replace later.

Common trade-offs

• Single application versus many services: one codebase is simpler to run but harder to grow. Many services scale better and are more expensive to operate.
• Build versus adopt: custom software fits the process but needs owners. Ready-made tools are cheaper to start and fixed in what they do.
• Flexibility versus stability: frequent platform changes can outpace the team that must maintain them.
