Mitgliederversammlung OdA ICT Bern Kurzreferat Cloud Computing 26. April 2012 Markus Nufer 1
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. 2
Cloud Computing Begriffe 3
Definition Wiki: 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 - Anwendung Jede 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: ondemand 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. * NIST National Institute of Standards and Technology http://www.nist.gov/itl/csd/cloud-102511.cfm 4

Nine server and eight attachable persistent storage options enable you to configure systems to match a wide variety of workloads. Virtual machine (VM) Options 32-bit configurations 64-bit configurations Copper Bronze Silver Gold Copper Bronze Silver Gold Platinum Virtual CPUs with 1.25 Gigahertz 1 1 2 4 2 2 4 8 16 Virtual memory (GB) 2 2 4 4 4 4 8 16 16 Instance storage (GB) 60 60+175 60+350 60+350 60 60+850 60+1024 60+1024 60+2048 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. *US prices for 32-bit copper configuration with Windows Server or SUSE Enterprise Linux, current as of December 5, 2011.

Storage Type Ephemeral Price is included in the instance hourly rate Volumes and sizes predetermined by instance type (60GB to 2TB) Persistent Flat hourly rate of $0.035 per 256GB per hour (~$0.10 per GB per month) for allocated block size. 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. Image Storage Flat hourly rate of $0.035 per 256GB (~$0.10 per GB/month) for actual image size Instance Specific Yes: Provisioned as part of the instance provisioning process. De-provisioned with instance. Partially: Mounted by one and only one instance at a time. Data and format is retained between mounts until block is deleted. No: Multiple instances can access stored objects. Accessible via the Internet, i.e. SCE instances not required. N/A: Image storage is not accessible by instances. Cloud infrastructure storage How to attach Backup Use cases Speed / Resiliency Attached at VM provisioning Only first 60 GB root segment is formatted Remaining storage to be formatted and mounted by the instance owner. 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 REST APIs Virtual NAS Appliance (CloudNAS) 3 rd party NAS Appliances Users can import images from persistent storage using API. Users can copy images to persistent storage using API. 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 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 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 Resilient storage is used; however, data is not disaster protected (no offsite copy). Application Data Database (tables, logs, etc.) Transactional data Data that needs to be retained beyond the life of an instance. Backup for other storage Archives, e.g. document retention storage Global data distribution Geo-replication for disaster protection Capture private VM Image Clone private VM Image Import private VM image 10 MB/sec 75 IO/s Not resilient against disk failure NAS (SONAS) shared across SCE hosts implemented using RAID6 hardware Hosts connected via shared 1 Gbit Ethernet, Relatively low performance 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 SCE provisioning processes has fast access to stored images for provisioning. RAID6 hardware 12
