Scalable VPS for SaaS Startup?

We need a scalable VPS solution to support a SaaS application.
Start with 8 vCPUs, 16 GB RAM, 200 GB storage, and the ability to upgrade easily as we grow.
Can you provide scaling options? Is GTHost.com reliable vps host? Any feedbacks?

VPS plans from legionbox.com and inet.ws can be quite right for meeting all your needs.
Their uptime, service and documentation are solid, so I rarely need support. But when I do, it’s just a call or click away!

Caching Technology. Built-in caching significantly improves website speed. Look for providers offering LiteSpeed, Varnish, or other caching tools.
SSL, backups, and security features included — I feel completely safe. GTHost.com offers feature-rich vps hosting. Everything is clearly organized for a great user experience.
