Transcript of Cloud Computing

Examples of Cloud Computing Google Drive What is Cloud Computing? Baseline storage: 5gb free
Upgrades: 100gb for $5/mo. If you opt to grow beyond the free baseline storage
Searching: Google Drive gives you the Google Docs online interface to search your document.
Transfer Bandwidth: there isn't any. Dropbox Baseline storage: 2gb of storage for free.
Upgrades: 50gb for $9/mo. If you opt to grow beyond the free baseline storage.
Dropbox is basically a file-retrieval system.
Transfer Bandwidth: there are some settings where you can control bandwidth usage. Characteristics On demand self-service
Resource pooling
Rapid elasticity
Measured service
Broad network access Cloud computing is a model for enabling on
demand access to a shared pool of computing resources. Cloud computing is the tendency of the future. Is a set of services offered through the Internet that let us access to software and hardware in a quickly and simply way. Definitions New capabilities Cloud is the evolution of industry transformation like virtualization and grid computing and it builts off of these by adding new capabilities such as..

Self-service
Policy-based scaling
Pay-per-use What is Cloud Computing? Utilities Applications most commonly operated in the cloud are:
Commodity applications such as email (50% of cloud users)
File storage (39%)
Web and video conferencing (36% and 32%)
Online learning (34%) How does it work? Structure There are three levels in cloud computing:
1.1 Infrastructure as a Service (IaaS): services that let us to access to machines and storage
1.2 Platform as a Service (PaaS): let us localized our applications and make them run into the cloud
1.3 Software as a Service (SaaS): let us consum software. It is accessible through the Internet, you pay it for use no for a license. The software is localized in provider house and is the same provider that put services around the software, most of them maintenance of the software (e.g. backups). & Advantages Disadvantages Security
Lock-in
Reliability
Lack of control Scale and Cost
Next generation Architectures
Encapsuled Change Managment
Choice and Agility Facebook Photos and videos are stored on Facebook servers, which are retrieved from any computer with an Internet connection. Microsoft SkyDrive Baseline storage: 7gb free
Upgrades: 100gb for $0,83/mo. If you opt to grow beyond the free baseline storage
Searching: brings all online content into one view
Transfer Bandwidth: it can't support selective synchronization that other clouds use business models Public cloud A public cloud is shared by multiple attendents and delivered by a third-party service provider. Public clouds offer: Lower upfront costs
Easier to manage, they don’t require the ID department to manage since a service provider is doing it
Less control Private cloud Is for the exclusive use of a single organisation and is managely controlled by the in-house ID department or their proxy They feature a lower total cost over the long-run
Easier integration with the existing ID operations
And greater control over security, complience and quality of service Hybrid cloud A single application runs across both public and private cloud this enables cloud bursting where an application runs on a private cloud in steady state but bursts out to use a public for workload peaks. (use public clouds for workload peaks). Impact of cloud computing RELATED
