Cloud Computing ist die grosse Veränderung in der ICT

Cloud Computing ist in aller Munde: als neuartige Technologie, als nächste Generation des Internets, als fundamentale Veränderung der gesamten IT-Landschaft und als vielversprechende Chance für neue Geschäftsideen und Wertschöpfungsketten.

Cloud Computing – Begriffe

DefinitionWiki: Es gibt unterschiedliche Arten von Cloud-Computing, eine mögliche Gliederung ist der sogenannte technische Cloud-Stack, mit drei Schichten, in der obere Schichten auf den unteren Schichten aufbauen können, es aber nicht müssen: Infrastruktur – Plattform - AnwendungJede Schicht stellt hier einen Grad an Abstraktion dar. Auf diese Art können auch die unterschiedlichen Typen von „Clouds“ klassifiziert werden.

The NIST* definition lists five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service. It also lists three "service models" (software, platform and infrastructure), and four "deployment models" (private, community, public and hybrid) that together categorize ways to deliver cloud services. The definition is intended to serve as a means for broad comparisons of cloud services and deployment strategies, and to provide a baseline for discussion from what is cloud computing to how to best use cloud computing.

• Intel architecture servers can be provisioned with Linux (Red Hat, Novell SUSE or customer provided) or Microsoft Windows Server (2003 or 2008) and your choice of middleware.

• Prices start well under 10 cents per hour* for a virtual machine, including operating system. Reserved capacity options provide pools of resources at discounted rates.

• Dynamically attach and detach up to three extra blocks of persistent (RAID protected) storage to an instance, preformatted (ext3) or raw in eight sizes from 60 GB to 10 TB.

Storage Type Instance Specific

How to attach Backup Use cases Speed / Resiliency

Ephemeral• Price is included in

the instance hourly rate

• Volumes and sizes predetermined by instance type (60GB to 2TB)

Yes:Provisioned as part of the instance provisioning process.

De-provisioned with instance.

• Attached at VM provisioning

• Only first 60 GB root segment is formatted

• Remaining storage to be formatted and mounted by the instance owner.

• Client is responsible for backup,.

• All data is captured in instance image capture process.

• Cloud backup solutions can be used as add-on service / agreement

• Application Data• Database (tables,

logs, etc.)• Transactional data

• 10 MB/sec• 75 IO/s• Not resilient against

disk failure

Persistent• Flat hourly rate of

$0.035 per 256GB per hour (~$0.10 per GB per month) for allocated block size.

Partially:• Mounted by one

and only one instance at a time.

• Data and format is retained between mounts until block is deleted.

• Attached to VM when the VM is provisioned or attach/detach dynamically.

• Up to 3 blocks per instance.

• Block sizes up to 10TB are provisioned from the SCE Console

• Client is responsible for backup,

• Storage units can be “cloned”. Must be detached prior to cloning.

• Cloud backup solutions can be used as add-on service / agreement

• Data that needs to be retained beyond the life of an instance.

• NAS (SONAS) shared across SCE hosts implemented using RAID6 hardware

• Hosts connected via shared 1 Gbit Ethernet,

• Relatively low performance

Object storage• Tiered pricing with

range $0.20 - $0.10 per GB per month depending on avg. daily usage in a month.

• Charges are for actually consumed storage.

No:• Multiple instances

can access stored objects.

• Accessible via the Internet, i.e. SCE instances not required.

• REST APIs• Virtual NAS Appliance

(CloudNAS)• 3rd party NAS

Appliances

• Customers can order copies of data in multiple data centers (currently max 2).

• Client can enable automatic background replication of data to multiple external data centers

• Backup for other storage

• Archives, e.g. document retention storage

• Global data distribution

• Geo-replication for disaster protection

• Speed is dependent on client Internet access from their point of access (inside or outside of SCE).

• Data Availability 99.9 to 99.99 depending on number of different data center copies.

• RAID hardware

Image Storage• Flat hourly rate of

$0.035 per 256GB (~$0.10 per GB/month) for actual image size
