A cloud-based software delivery model where applications are hosted by a vendor and accessed by users via the internet, typically on a subscription basis.
Instead of forcing users to download and install heavy software on their personal computers, SaaS allows users to simply log in via a web browser to access the tool. Popular examples include Google Workspace, Slack, Zoom, and Salesforce.
Building a SaaS platform is a highly lucrative business model because it provides recurring subscription revenue (Monthly Recurring Revenue or MRR).
Key Architecture Requirements for SaaS:
- Multi-Tenancy: A single instance of the software serves multiple customers (tenants), with strict data isolation.
- Subscription Billing: Automated handling of monthly/annual billing, upgrades, and cancellations via Stripe or Paystack.
- High Availability: Cloud infrastructure that guarantees 99.99% uptime for enterprise users.
Developing a scalable SaaS architecture requires deep expertise in cloud databases, user authentication, and multi-tenant architectures—areas where SkyFig Technologies excels.
