Just Cloud Managed Hosting for you to grow at your own pace
It's called fixed-rate hosting because you probably don't want a different bill in each period, but rather pay the same amount during the year regardless of how much space, bandwidth, and other parameters take up. If this is your case, you should previously define the resources that you will use during the year so that you pay the same rate during your entire stay period. Once you define your parameters you can adjust them to your convenience.
It's called on-demand hosting because you pay only for what you actually use. Within your control panel you will have access to a space and bandwidth meter. You will also have options to acquire other parameters such as input and output speed, number of processors, RAM memory, etc. Your server is hosted in the cloud and can grow as the traffic and use of your web resources grows.
