A Practical Architecture and Operating Model for Small Businesses

Most small businesses do not need enterprise-scale AI architecture.

Important Note:
The solutions presented are intended as reference examples only. They are not universal recommendations, as every SME has unique operational requirements, technical maturity levels, and budget considerations. The most suitable solution should be tailored to each organization’s specific business needs and growth objectives.

What they need is:
