Since we are being asked all the time what kind storage performance can we get from different cloud infrastructure providers we run a little test. Following chart is based on simple " hdparm -t" command allowing us to get a glimpse on read performance of different devices. We checked Amazon EC2 Elastic storage as well as instance store (for explanation about AWS storage options click here ), both local and NAS storage options from Softlayer, Linode and Hetzner. Amazon instance store is the fastest storage option in our test but it is being cleared on restarts making it impossible to use for persistent operations. Softlayer on the other hand demonstrated very good performance on both local storage (persistent) and NAS being more then twice faster then Amazon EBS. Great performance from Linode and low end Hetzner being just a bit faster them Amazon. Following is a graph with results. If you have any questions or suggestions
Infrastructure as a service (IaaS) allows a third-party to house the equipment that includes storage, servers and other networking elements, outsourcing completely all the issues related to infrastructure management. The third-party owns the equipment and has responsibility of maintaining and housing it, while ensuring full functionality.
Main characteristic that makes IaaS useful is dynamic scaling, as an IaaS user you are free from traditional constrains of capacity planning - hardware making it easier and faster to deploy needed infrastructure and cutting costs by eliminating payment for non used resources.
IaaS comes in different types, such as Public and Hybrid Cloud and are supplied by different providers. You can find more information on IaaS types here and we have also short IaaS providers comparison page, both being constantly updated.
We are adding more information about clouds in general. Below are some definitions for better understanding IaaS concepts.
Public Cloud. The cloud infrastructure is made available to the general public or a large
industry group and is owned by an organization selling cloud services.
Private Cloud. The cloud infrastructure is operated solely for a single organization. It
may be managed by the organization or a third party, and may exist on-premises or off premises.
Community Cloud. This cloud type is an infrastructure shared by several organizations and
supports a specific community that has shared concerns (e.g., mission, security
requirements, policy, or compliance considerations). It may be managed by the
organizations or a third party and may exist on-premises or off-premises.
Hybrid Cloud consists of two or more infrastructure types that can be clouds (private,
community, or public) or cloud and physical. Both types are bound together to provide single scalable infrastructure.
