7. Serverless and edge architectures
Serverless functions and edge runtimes help deliver dynamic content closer to users, reduce infrastructure management, and scale automatically. Market data shows continued growth through 2025, indicating broad adoption across industries.
According to a report by Precedence Research, the global serverless architecture market is projected to increase from 22.23 billion(USD) to 124.52 billion(USD) in 2026, with edge computing bringing computational power closer to users. Use serverless for event‑driven workloads and edge for latency‑sensitive routing or personalization.
Benefits of serverless frontend architecture:
- Automatic scaling: resources adjust based on demand
- Reduced infrastructure costs: pay-per-use pricing models
- Faster time-to-market: no server configuration required
- Global performance: edge deployment for reduced latency
- Simplified maintenance: cloud providers handle server management
8. Voice user interfaces and conversational design
Voice input and natural language features are increasingly used to improve accessibility and convenience. Practical web integrations include the Web Speech API for recognition and synthesis, paired with a fallback UI for different contexts and user preferences. Design multimodal experiences that respect privacy and give you control.
Voice interface implementation strategies:
