Shared hosting is the cheapest type of web hosting package available. In this tier, you will rent space on a shared server where other websites are hosted. While you will pay less, in most cases as little as $5 a month, this web hosting plan offers the least security, performance, and flexibility. If you are running on low budget, the website is not important to your business, or you cannot afford VPS or dedicated hosting, or you are getting started online, this might be a good plan for you.
Virtual Private Servers, in short VPS, are a cross between dedicated servers and shared hosting. In this case, one physical server accommodates several VPS instances. Simply put, your website is granted a strict portion of the parent server's hardware resources - your server portion operates independently from all other websites on the server.
VPS hosting is affordable (though more expensive than shared hosting), scalable, flexible, and cost effective. This hosting options is ideal for small and medium sized businesses not running on low budget. Again, you will manage most aspects of your website and as such, you need to understand a thing or two about web configurations.
A dedicated server hosting is the gold tier of web hosting. Here, you get a single server all dedicated to your business. You will share network with other dedicated servers in the data centre but you will not share hardware.
Dedicated servers are very expensive for small and medium sized businesses - more expensive than virtual private servers. However, they offer the best performance, security, flexibility, and scalability for your business in Australia.
While not technically part of web hosting there's also email hosting where you have a specialist third party provider help manage your email system whether it be on popular platforms like Outlook or on Google.
