Server Infrastructure for B2B SaaS

Recommended builds by size

Three sizes of operation, each sized from an assumed traffic figure.

Small

1–10 people · ~5,000 visits a month

VPS

Single Core
8 GB RAM
80 GB storage

A single site or team, with traffic that arrives in a predictable working-hours pattern.

Medium

11–50 people · ~50,000 visits a month

VPS

Single Core
16 GB RAM
200 GB storage

A growing business running several systems, where an outage now costs real money.

Large

51+ people · ~500,000 visits a month

VDS

8 Cores
64 GB RAM
700 GB storage

Multiple sites or a busy platform, with traffic that spikes and an obligation to stay up.

Which tiers suit B2B SaaS

Infrastructure	Verdict	Why
Shared Hosting Managed space on a shared server	Not this one	Shared hosting cannot run background workers, queues or long-lived processes, which a SaaS application depends on.
VPS Flexible virtual infrastructure with full root access	Recommended	The natural home for an early-stage product: root access, your own runtime, and the ability to resize as you grow.
VDS Virtual server with resources pinned to you alone	Recommended	Pinned resources give you the predictable latency your customers will hold you to in an SLA.
Dedicated Server An entire physical server, configured to your specification	Recommended	Right once the database and the application tier are competing for the same memory on a single virtual instance.
Bare Metal Physical compute for sustained, demanding workloads	Workable	For platforms running their own virtualization, or holding a large working set entirely in memory.

B2B SaaS workloads you can host

Business-hours traffic in a handful of time zones, and an SLA that makes the quiet hours the wrong time to be resizing.

B2B SaaS hosting — FAQs

What server specification do B2B SaaS usually need?

It depends on volume more than on the industry. A medium-sized operation working from about 50,000 visits a month lands around single core, 16 GB of memory and 200 GB of storage.

How were these figures worked out?

From an assumed traffic level, the number of requests each page makes, and how much data the application keeps warm — then rounded up to a build we actually sell. They are assumptions stated out loud rather than measurements of your business.

Can we change size later?

Yes. Memory, cores and disk can all be raised on the same server, usually within the hour, with no rebuild and no new IP address.
