Common Questions About Web Application Development
Transparent answers regarding timelines, intellectual property, integrations, and architectures.
What is the difference between a website and a web application?
A website primarily delivers informational content, whereas a web application features complex business logic, user logins, transactional data processing, and custom interactive workflows.
Can Sonexa build a multi-tenant SaaS application?
Yes. We have extensive experience engineering multi-tenant SaaS architectures with strict tenant data segregation, billing integrations (Stripe, Razorpay), and automated provisioning.
How do you ensure data security in web applications?
We employ OWASP security standards, end-to-end data encryption in transit and at rest, parameterized database queries to prevent SQL injections, CSRF protections, and strict role-based access control.
Can you scale a web application if traffic surges 10x?
Yes. We design applications using containerized microservices or serverless architectures with automated horizontal scaling and Redis caching to easily absorb sudden traffic spikes.
