Web hosting
Short definition
Hosting is the service that keeps a website's files on a server permanently connected to the internet, day and night.
A website is really just a set of files sitting somewhere; hosting keeps those files on a server that stays online. Shared hosting, VPS and cloud servers differ mainly in how resources are divided among sites.
On cheap shared plans, resources are split with other sites, so a spike in traffic can slow everyone down. Businesses with more demanding needs usually move to a VPS or a managed cloud setup with dedicated resources.
The hosting choice shapes speed, security, backup frequency and support quality all at once. A plan that looks cheap can quickly become a bottleneck as a business grows.
The resource usage section of the hosting control panel shows disk space, bandwidth and processor consumption on a regular basis, the most concrete way to see when capacity is starting to run out. If those figures keep creeping toward the ceiling, that is the sign it is time to move up a plan before the site slows down noticeably.
Why it matters
Slow or frequently interrupted hosting drags down both search rankings and customer trust together. Choosing the right hosting is the guarantee that growth in traffic will not break the site.
Illustrative example
A flooring manufacturer tripled its traffic during a campaign and found its old shared hosting could not cope, moving to a plan with dedicated resources kept the site stable.
