Every online shop needs a baseline of server specs to run well. The main ones are a modern PHP version, enough memory, fast storage, a solid database and SSL.
Ecommerce hosting requirements centre on a current PHP version, at least 256MB memory, fast SSD or NVMe storage, a reliable database and a free SSL certificate.
Why requirements matter
Store software makes real demands on a server. Meet them and the shop runs smoothly. Fall short and pages crash, checkouts fail and updates break. Knowing the specs helps you pick a plan that will not let you down.
The requirements here are platform-agnostic. Whether you run WooCommerce, Magento or another open-source store, the same core specs apply. Numbers vary a little, but the shape stays the same.
PHP version
Most open-source store software runs on PHP. A modern PHP version runs faster and stays secure, since old versions stop getting security fixes. Aim for a recent, supported release and keep it current.
- Current release. Run a supported PHP version so you get speed gains and security patches.
- Easy switching. Good hosts let you change the PHP version from a control panel in seconds.
- Required extensions. Store software needs certain PHP extensions, so check the host enables them.
Memory and processing
Store pages are heavy. Product filters, carts and checkouts all use memory, so a cramped limit causes crashes. A minimum of 256MB of PHP memory is a safe floor, and busy shops want more.
- PHP memory limit. Aim for 256MB or higher, since add-ons and busy pages eat into it fast.
- Enough RAM. Server memory lets the store cache more and handle more shoppers at once.
- Processing power. Faster processors build pages quicker, which keeps checkout snappy under load.
A low memory limit is one of the most common causes of a broken checkout. When in doubt, ask the host to raise it.
Storage and databases
Fast storage speeds up every database query, and a shop makes many. Solid-state drives, and NVMe drives in particular, read data far quicker than old spinning disks. A reliable database engine ties it all together.
- SSD or NVMe. Fast drives cut the time each query takes, which speeds product and category pages.
- A solid database. A well-tuned MySQL or MariaDB engine handles store queries reliably.
- Room to grow. Orders, products and images add up, so pick storage that scales with the shop.
SSL and security basics
Every shop needs SSL, the certificate that adds the padlock and encrypts data. Without it, browsers warn shoppers away and card payments will not process. Most hosts now include a free certificate.
Beyond SSL, look for a firewall, malware scanning and daily backups. Those protect customer data and orders. Our guide on security and PCI compliance covers the full picture.
Bandwidth and uptime
Bandwidth is how much data your store can send. A shop with images and traffic uses plenty, so check the plan offers enough or is unmetered. Watch for caps that trigger fees during busy months.
Uptime is how often the store stays online. Aim for a host that promises 99.9% or better, since every minute offline is a minute you cannot take orders. Reliability like that is worth paying for.
Matching specs to your host
A host tuned for shops meets these requirements out of the box, so you rarely have to check each one. Basic hosts sometimes fall short on memory or storage, which is where trouble starts.
Software and control panel needs
Beyond raw specs, a shop needs the right supporting software. A host that bundles these tools saves you setup time and keeps the store easy to manage day to day.
- A control panel. A clear dashboard to manage files, databases and email makes the store far easier to run.
- HTTPS support. The host should serve your store over a secure connection by default, backed by the SSL certificate.
- Email deliverability. Order and account emails need to reach inboxes, so check the host supports reliable sending.
Check the host lets you tweak these settings without a support ticket for every change. A shop owner who can adjust PHP, caching and email from a panel keeps the store healthy with far less friction.
When comparing plans, match the specs above against your catalogue and traffic. Our best ecommerce hosting guide highlights which hosts meet the requirements a busy shop needs, and our guide on what ecommerce hosting is explains the basics behind them.
Frequently asked questions
What PHP version does an online shop need?
Run a modern, supported PHP release. Older versions lose security fixes and run slower. Good hosts let you switch the version from a control panel in seconds, so keeping it current is easy. Check the required PHP extensions are enabled too.
How much memory does ecommerce hosting need?
Aim for a PHP memory limit of at least 256MB. Store add-ons and busy pages eat into it quickly, and a low limit is a common cause of a broken checkout. Busy shops with large catalogues want more headroom than the minimum.
Do I need SSD or NVMe storage?
Fast storage helps a lot, since a shop makes many database queries. Solid-state drives, and NVMe drives especially, read data far quicker than old spinning disks. That speeds up product and category pages and keeps the store responsive.
Is SSL a hard requirement for a shop?
Yes. SSL adds the padlock, encrypts data and lets card payments process. Without it, browsers warn shoppers away and gateways refuse to work. Most hosts now include a free certificate, so there is no reason to run a shop without one.
What uptime should I expect from a host?
Look for a promise of 99.9% or better. Every minute offline is a minute you cannot take orders. A reliable host with monitoring keeps downtime rare and short, which protects both sales and shopper trust.
