Google Preemptible Virtual Machines Are Now Available
After being in beta for a few months, Google has announced the general availability of its Preemptible Virtual Machines. These new Virtual Machines cost less than the usual cloud VMs from Google.
While many called it game changer when Google talked about it back in May, the cheaper cost comes with a catch. Google can turn the VMs off anytime it feels the need of extra computing power. There are other limitations as well:
- Compute Engine always terminates preemptible instances after they run for 24 hours.
- Preemptible instances are finite Compute Engine resources, so they might not always be available.
- Preemptible instances cannot live migrate or be set to automatically restart when there is a maintenance event.
These VMs are being offered using leftover computing power of Google’s servers, so that is the reason Google can turn them off when more power is needed. Due to this very reason, this solution may not be suitable for every type of application.
That means any application using Google’s VMs should be fault tolerant to withstand downtime. However, Google has found interest in VMs from both big and small consumers:
During our beta, many customers both big and small have used Preemptible VMs to realize savings for themselves — in the areas of genomics and pharmaceuticals, financial modeling and simulation, rendering, media transcoding, manufacturing design, big data, and web crawling to name a few.
