Razyr offers two classes of managed cloud server instances. Both classes can be scaled essentially infinitely, adding as much compute resource as your application and budget demands.
Auto-Scaling instances can resize on demand and requires the pre-purchase reservation of compute resources. This is a small annual fee and you pay the full resource cost only when it is in use. Auto-scaling instances can be scheduled so that your compute resources follow your demand. For example a CPU/Memory intensive application which serves a group of research scientists from 9am-5pm daily could be downsized nightly from 6pm-8am.
Manual-Scaling instances can be rescaled by opening a support ticket. Depending on the underlying cloud platform and the instance operating system, we will usually schedule memory or CPU changes during off-peak hours.
We have somewhat more flexibility for scaling with our Amazon Web Services instances, but at higher cost than our OpenStack service hosted in Canada.
