Transcript of Cloud Computing

Cloud Computing Cloud Computing Introduction Cloud Characteristics Management Issues Advanced Cloud Applications The “cloud” is a metaphor for the Internet. Cloud computing: a model for enabling convenient, on-demand network access to shared computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.
— National Institute of Standards and Technology (NIST). On-Demand Self Service Ubiquitous Network Access Rapid Elasticity Resource Pooling You get what you pay for (and pay only for what you get)
Aspects of the cloud service are controlled and monitored by the cloud provider
This is crucial for billing, access control, capacity planning and other tasks.
Three measured service models
Software as a Service
Platform as a Service
Infrastructure as a Service Software as a Service Platform as a Service Infrastructure as a Service Types of Clouds Strategic Issues Technical Issues Many of the benefits of Cloud computing have made it quite popular but management must weigh both pros and cons... Scalability - Will the provider be able to meet the current and future business needs?
Viability - Will the provider survive in the long run?
Diversity of Offerings - Will the provider offer other services that may be needed in the future?
Support Policies - How will issues and outages be resolved? Will they be handled quickly and efficiently? Availability/Reliability - Promised up-time of applications or systems? Routine backups of data? Sufficient bandwidth?
Security - How secure is the data to outside intruders?
Compliance - Does the data storage comply with industry standards?
Privacy - Will the privacy of customer data be protected?
Openness - How easy would it be to switch providers? Are we locked into this provider? Grid Computing provides supercomputing power without the overhead and cost associated with owning such assets. The End Any Questions? The most basic form of cloud computing
Provider licenses an application to customers for use as a service on demand
No third-party development or resources for the user
SaaS offers tools directly from web browser
Examples Include: Delivery of uniform computing platform
Allows users to develop applications without infrastructure concerns Delivery of an entire computer infrastructure is provided
Network Public
Companies with few regulations that need to get a service to market quickly
Businesses that must comply with strict regulations
Highly critical applications
Comprised of public and private cloud services It's there when you need it
Resources are accessible anytime without interaction with the provider
Cafeteria style consumption
choose the resources you need The ability to quickly scale resources up or down as needed.
Cloud infrastructure is able to mirror user demand If interested in a Free 50GB Cloud Storage with Box let us know!!! https://www.box.com/signup/o/dell_50gb_give_get Cloud services are accessible from almost anywhere on any web-enabled device Cloud provider serves many consumers through multi-tenancy
Allows service to multiple customers from a single shared instance of the application Traditional Hosting Cloud Hosting vs. Edge Computing moves the processing and data storage to the "Edges" of the network instead of centralized model. In many situations this can improve a companies performance. Measured Service
