Scalr vs OpenNebula: What are the differences?

Scalr: Scalr is cloud management software for public & private infrastructure. Scalr is not an infrastructure provider or reseller. The infrastructure you deploy on is yours: you give us the keys to your infrastructure cloud so we can make the API calls to the provider on your behalf and so we can also rev up or power down servers for you. When traffic piles up, Scalr detects the increased load, commissions new servers for you from the cloud, and then spreads the load. When using Scalr ConfigTemplates, you can easily make configuration changes for services such as MySQL and Apache. Scalr does the heavy work, pushing those changes out to your servers; OpenNebula: A cloud computing platform for managing heterogeneous distributed data center infrastructures. It provides a simple but feature-rich and flexible solution for the comprehensive management of virtualized data centers to enable on-premise enterprise clouds in existing infrastructures. It can be primarily used as a virtualization tool to manage your virtual infrastructure in the data-center or cluster, which is usually referred as Private Cloud. It supports Hybrid Cloud to combine local infrastructure with public cloud-based infrastructure, enabling highly scalable hosting environments.
