What Is Web Hosting and What Do You Actually Need?
Hosting is rented space on a computer that answers when someone types your address. Here is what a host really provides, how it differs from your domain and your email, and which type is worth paying for.
Web hosting is rented space on a server that stores your website’s files and sends them to anyone who visits. Australian small businesses usually pay $15 to $80 a month excluding GST. Shared hosting is fine for a brochure site, managed WordPress suits any site that generates enquiries, and a VPS only earns its cost once traffic or custom software demands it.
The word gets used loosely, which is where the confusion starts. A host is not your website, your domain name, or your email, even though one company probably sells you all three on one invoice. Separating those in your head is the most useful thing you can do before comparing a single plan.
We have been hosting sites for Australian businesses since 2004, and the question that decides it is rarely which plan is fastest. It is who answers when it breaks.
What does a web host actually provide?
Disk space, a share of a server’s processing power, and a connection that stays up. Everything else is packaging. When someone types your address, their browser asks a server for your files, and the host’s job is to hand them over quickly, every time, all year.
A decent plan includes storage for your files and database, PHP and MySQL at current supported versions, an SSL certificate so the site loads over HTTPS without a browser warning, server level caching, backups at a stated frequency, and support from people who can read a server log.
Notice what is missing. Your design, your content, your plugin licences and your WordPress updates are all separate. Hosting keeps the lights on, it does not maintain the building.
What is the difference between a domain, hosting and email?
Three separate services that people treat as one bill. The domain is the address someone types. The hosting is the space the website occupies. Email is a different system entirely that happens to use the same domain name, and it is often supplied by a different company again.
You can buy all three from one provider, or split them across three. Nothing breaks. They are joined only by DNS records, which tell the internet that yourbusiness.com.au points to this server for the website and that one for the mail.
This matters when something stops working, because the first useful question is which of the three failed. Site down but email fine is a hosting problem. Email bouncing while the site loads is a mail problem. Nothing resolving at all usually means the domain expired.
Which type of hosting do you need?
Four types are worth knowing about, and for most Australian small businesses the honest answer is quality shared hosting or managed WordPress. Dedicated servers are almost never the right call now, and a VPS is usually bought too early.
| Hosting type | Typical cost (ex GST) | Who it suits | Main limitation |
|---|---|---|---|
| Shared | $5 to $30 per month | Brochure sites, sole traders, tradies, anything under roughly 15,000 visits a month | You share CPU and memory with dozens of other sites, so a noisy neighbour can slow you down |
| VPS | $40 to $200 per month | Busier sites, custom applications, agencies running a handful of client sites | Unmanaged by default, so you are the sysadmin unless you pay for management on top |
| Dedicated server | $200 to $600 per month | High traffic platforms, heavy databases, specific compliance requirements | Expensive, and you carry the full maintenance burden for capacity you will not use |
| Managed WordPress | $30 to $120 per month | Any WordPress site the business depends on for leads or sales | Plugin restrictions, and cheaper tiers can be strict about monthly visit limits |
The jump worth paying for is from budget shared to either quality shared or managed WordPress. Roughly $200 to $600 extra a year, and it buys server level caching, a staging site, backups you can actually restore, and support who will not immediately tell you to contact your developer. Our Australian hosting and maintenance plans sit in that band deliberately, because it is where the pain stops. The next jump is usually premature: if someone quotes a VPS for a fifteen page site doing 2,000 visits a month, ask what problem it solves.
Rule of thumb: keep your domain at a registrar that is not your host. It costs nothing extra, and if the hosting relationship sours you still control where the address points. We have watched businesses lose weeks to a host who was slow to release a domain during a dispute.
Does server location matter for Australian visitors?
Yes, for the first response. A Sydney server answering a Sydney visitor takes roughly 10 to 30 milliseconds per round trip. The same request to Texas is closer to 180 to 220 milliseconds, and a page load involves dozens of round trips, so an overseas server can add half a second before a single image appears.
A CDN changes that maths. Cloudflare and similar services cache your images, CSS and JavaScript on servers in Sydney, Melbourne and Perth, so those files come from down the road no matter where the origin sits. What a CDN cannot fix is the dynamic part: the HTML WordPress builds fresh each time, plus anything logged in, in a cart, or behind a form.
So: Australian audience and a transactional site, host locally and put a CDN in front of it. A well configured overseas managed platform with caching and a CDN narrows the gap enough that it rarely justifies a migration on its own.
What does unlimited hosting really mean?
Unmetered, not unlimited, with a fair use clause several screens down the terms of service. Nobody can sell infinite disk or infinite processing. What they can do is stop counting gigabytes and start throttling the things that actually cost them money.
The limits that bite are never printed on the pricing page:
- CPU allocation, often a percentage of one core. Exceed it and requests queue, which visitors experience as a site that intermittently crawls.
- Entry processes, the number of scripts allowed to run at once, commonly 20 to 40 on shared plans. A slow plugin or a traffic burst hits that ceiling and visitors get a 508 error.
- Inodes, a count of files and folders rather than their size, typically capped between 200,000 and 500,000. WordPress with a page builder and a year of cached thumbnails gets closer than you would expect, and hitting the cap often blocks backups and email at the same time.
- Database size and simultaneous connections, which quietly breaks WooCommerce stores during a sale.
Ask any prospective host for those four numbers in writing.
Who is responsible for your backups?
You are. Nearly every host’s terms include a line saying backups are a courtesy and the customer is responsible for keeping their own copies. That is standard rather than sneaky, but it means the backup you assume exists may not be the one you need.
Three questions settle it. How often are they taken, how long are they kept, and can you restore one yourself at 9pm on a Saturday without lodging a ticket? Daily backups held for 30 days with self service restore is a fair standard. Weekly held for seven days is not, because plenty of problems go unnoticed for a fortnight.
The other trap is backups stored on the same server as the site. If the drive fails or the account is suspended, both copies go together. Keep an off server copy.
What does 99.9 per cent uptime actually allow?
Just under 45 minutes of downtime a month, and about 8 hours 45 minutes a year. That is the figure almost every host advertises, and it is far less impressive once converted. At 99.99 per cent you are down about 4 minutes a month. At 99 per cent, which some budget hosts quietly offer, more than 7 hours.
Read what counts. Scheduled maintenance is usually excluded, as are problems caused by your own plugins, code or traffic, which covers a fair share of real outages. The remedy is normally a credit against the fee, so a full day offline might earn you $2 back on a $60 plan. Treat the SLA as a signal of intent, not insurance, and run your own monitoring with something like UptimeRobot.
What are you really paying for when you buy hosting?
Support. Servers are close to a commodity now, and the specification gap between a $10 plan and a $50 plan is smaller than the price gap suggests. The premium buys a person who answers, understands WordPress rather than just Linux, and can tell a plugin conflict from a server fault.
Test it before you commit. Send a pre sales question at 8pm on a weeknight and see what comes back and how fast. Ask something specific, like whether they support WP-CLI, and judge whether the reply reads like a human or a template. When the site is down and enquiries are stopping, that first reply is the entire product. There is more on this across our hosting and WordPress guides.
How do you move hosts without downtime?
Done properly, a migration causes no visible downtime. The new site is built and tested before anything public changes, so the switch itself is only DNS pointing somewhere different. A typical WordPress move is two to four hours of work plus a settling period.
- Copy the site to the new server and test it on a temporary URL or via your local hosts file. Check forms, payments and integrations, not just the home page.
- Set up email on the new provider first and confirm you can send and receive before touching anything live.
- Drop your DNS TTL to 300 seconds at least 24 hours ahead, so the change propagates in minutes rather than hours.
- Put the old site into a read only state briefly, sync the database one final time so no orders or form entries are lost, then change the A record.
- Install and verify SSL on the new host, then check for mixed content warnings.
- Keep the old hosting running for at least 14 days. One extra month is the cheapest insurance in the whole process.
Email is the part that goes wrong, not the website. Mailboxes need copying across with an IMAP sync and MX records changing at the right moment, or messages bounce. If you would rather not run that sequence, we handle migrations when you move hosting to us and do not charge for the move itself.
Before signing anything, ask for the renewal price, not the introductory price. Hosting is one of the few recurring costs where year two can be double year one, and it is disclosed in a footnote rather than on the pricing table.
Common questions
Can I host a website myself?
Technically yes, practically no. A home connection has a dynamic IP address, upload speeds well below what a server needs, and no protection when the power drops. You would also own security patching, firewall rules and mail deliverability. Unless hosting is a skill you want to learn, $20 a month buys infrastructure you could not replicate at home for ten times the price.
Do I need hosting if my site is on Wix or Squarespace?
No. Those platforms include hosting in the subscription, which is part of the appeal. The trade off is that you cannot move the site anywhere else, because there is no file archive to take with you, so leaving means rebuilding. With WordPress the hosting is a separate bill, but you own the files and the database and can move to any host that will take them.
How much disk space does a small business website need?
Far less than most plans offer. A typical fifteen page WordPress site with a few hundred images sits between 1GB and 3GB including the database. Even a modest store rarely passes 10GB. If a host is pushing 100GB at you, they are selling storage you will never touch instead of the CPU and memory that actually affect speed.
What is cPanel and do I need it?
cPanel is the control panel many shared hosts use for managing files, databases, email and backups. It is familiar and capable, and if you ever hand the site to another developer, most of them know it. Managed WordPress hosts often use their own panel instead, which is usually simpler but gives you less direct access to the server underneath.
Can I keep my email if I move web hosts?
Yes, and plan for it separately. Mailboxes are copied with an IMAP sync tool so nothing is lost, then MX records are updated once the new mailboxes are confirmed working. Many businesses use the move as a chance to shift email off the web host entirely to a dedicated mail provider, which is generally the more reliable long term arrangement.
Does hosting affect my Google rankings?
Indirectly. Server response time feeds into Core Web Vitals, and a site that is regularly unreachable when Google crawls it gets indexed less thoroughly. Nobody can promise better rankings from a hosting upgrade, and be wary of anyone who does. What is fair to say is that a slow first response loses you visitors before search engines are even part of the conversation.
Is Australian hosting always faster than overseas hosting?
Not always. A well tuned overseas managed WordPress platform with full page caching and an Australian CDN edge can beat a poorly configured Sydney server. Location sets the floor on latency; caching, PHP version and server load decide the rest. If your audience is Australian and your site is dynamic, local hosting remains the safer default.
Not sure what you are paying for?
Send us your current hosting invoice and we will tell you straight whether it is good value, what the renewal will cost, and whether moving is worth the effort. Australian support, no lock-in contracts, migrations included.
