Reliable cloud with a slightly higher cost and not top performance

IBM Cloud Virtual Servers are well suited in scenarios when you need some compute power in a very reliable data center with many certifications useful for compliance. The other thing I like is that the VM pricing is clear and there are no weird calculations to do.

• Often poor performance. If the VM happens to be on an "unlucky" host because other customers are using resources, you have to open a case and ask for moving the VM to another host.

• Tickets are often responded to after hours or days.

• The KVM is very bad (based on Java, it does not work on modern browsers but must be opened via a VNC client) and often does not work (also, here you have to ask the support).

• The VMs are based on XenServer. The drivers must be updated often and the procedure to update them is absurd (after the update the network configurations are lost and you have to reboot, login with the KVM, and restore them). If you do not update the drivers you have stability and crash problems, especially with Windows.

• They often do maintenance with downtime and automatic VM restarts.

• The firewall they propose (Vyatta) is the most inconvenient to use I've ever seen. The alternative is to rely on very simple and limited network rules.

• The amount of internet traffic included is low and the costs to exceed the included ones are very high.
