OpenStack vs Scalr: What are the differences?
What is OpenStack? Open source software for building private and public clouds. OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.
What is 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.
OpenStack and Scalr are primarily classified as "Open Source Cloud" and "Cloud Management" tools respectively.
Some of the features offered by OpenStack are:
