If you are scrambling for new hosting today you really should check out Prometeus I have been using them for nearly a decade and have yet to find a less expensive option. Their support staff are very capable and responsive.
I can’t praise them highly enough.
Update (next day). Please see my later post below.
Eg:
VPS SSD PRO7
Professional SSD VPS
Full root access
VPS SSD PRO7€3.90
» Operating System: ubuntu-16.04-x86_64€0.00
» RAM: 4 GB€4.00
» SSD Disk Space: 50GB€1.50
» Bandwidth: 2000 GB€0.00
» vCPU: 2€1.00
» Number of IPs: 1€0.00
» Location: Italy€0.00
Setup Fees:€0.00
Monthly:€10.40
VAT @ 22.00%:€2.29
€12.69
They also have bill-by-the-hour VMs :
vCPU 4 vCPU
RAM 4 GB
IPs 1
Incoming Traffic FREE
Outgoing Traffic 2 TB / Month
€/ Hour € 0.020 / Hour
50 GB DISK € 0.005 / Hour
--------
€/ Month € 18.00 / Month
These VMs are hosted in Apache CloudStack so you have complete control over ISOs,OS installation Storage and Storage Templates, Snapshots, starting, stopping and reverting to earlier snapshots, either via the CloudStack admin portal or through the REST API with cURL, Postman or whatever.
Able to start and end VM usage during testing and staging in a CI/CD process means you’re unlikely to find a cheaper option.
