  1. 1. CLOUD COMPUTING A PRESENTATION BY: MUHAMMAD USAMA ZUBERI AHMED RAZA USAMA SARWAR
  2. 2. WHY WE CALL IT CLOUD COMPUTING? The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network on telephony schematics and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents.

  4. 4. WHAT IS CLOUD COMPUTING? Cloud Computing Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four deployment models.

  6. 6. WHAT IS CLOUD COMPUTING? Cloud Computing “The practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer is called Cloud Computing.”
  7. 7. ESSENTIAL CHARACTERISTICS  On-demand self-service A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without human interaction with each service provider.  Broad network access Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Source: NIST Special Publication 800-145
  8. 8. ESSENTIAL CHARACTERISTICS  Resource Pooling The provider’s computing resources are pooled to serve multiple . Resources can be dynamically assigned and reassigned according to customer demand. Customer generally may not care where the resources are physically but should be aware of risks if they are located offshore. Source: NIST Special Publication 800-145
  9. 9. ESSENTIAL CHARACTERISTICS  Rapid Elasticity Capabilities can be expanded or released automatically (i.e., more CPU power, or ability to handle additional users) To the customer this appears seamless, limitless, and responsive to their changing requirements.  Measured Service Customers are charged for the services they use and the amounts There is a metering concept where customer resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

  10. 10.  Public Cloud - Available to general public. (Sharable Storage) “Public clouds are owned and operated by a third-party cloud server provider, which deliver their computing resources like servers and storage over internet.”  Microsoft Azure is an example of public cloud.  Private Cloud - Resources available to single user or an organization. (Dedicated Storage) “A private cloud refers to cloud computing resources used exclusively by a single business or organization.”  Amazon Elastic Compute Cloud (EC2) is an example of private cloud. DEPLOYMENT MODELS
  11. 11. Hybrid Cloud - A mixture of Public & Private Clouds. “Hybrid clouds combine public and private clouds, bounds together by technology that allows data and applications to be shared between them.” Community Cloud - Shared infrastructure for specific community - several orgs that have shared concerns, - managed by org or a 3rd party “A collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns whether managed internally or by a third-party and hosted internally or externally.” DEPLOYMENT MODELS
  12. 12. SERVICE MODELS
  13. 13. Infrastructure-as-a-Service (IaaS)  A service model that involves outsourcing the basic infrastructure used to support operations--including hardware, servers, and networking components.  The service provider owns the infrastructure equipment is responsible for housing, running, and maintaining it. The customer typically pays on a per-use basis.  The customer uses their own platform (Windows, Unix), and applications SERVICE MODELS
  14. 14. SERVICE MODELS Platform-as-a-Service (PaaS)  A service model that involves outsourcing the basic infrastructure and platform (Windows, Unix)  PaaS facilitates deploying applications without the cost and complexity of buying and managing the underlying hardware and software where the applications are hosted.  The customer uses their own applications.
  15. 15. SERVICE MODELS Software-as-a-Service (SaaS)  Also referred to as “software on demand,” this service model involves outsourcing the infrastructure, platform, software/applications.  Typically, these services are available to the customer for a fee, pay-as-you-go, or a no charge model.  The customer accesses the applications over the internet.
  16. 16. SERVICE MODELS Apps for Business
  17. 17.  Improved performance: – With few large programs hogging your computer's memory, you will see performance from your PC. – Computers in a cloud computing system boot and run faster because they fewer programs and processes loaded into memory…  Reduced software costs: – Instead of purchasing expensive software applications, you can get most of what you need for free-ish!  most cloud computing applications today, such as the Google Docs suite. – better than paying for similar commercial software  which alone may be justification for switching to cloud applications. Advantages of Cloud Computing
  18. 18. Advantages of Cloud Computing  Unlimited storage capacity: – Cloud computing offers virtually limitless storage. – Your computer's current 1 Tera byte hard drive is small compared to the hundreds of Peta bytes available in the cloud.  Increased data reliability: – Unlike desktop computing, in which if a hard disk crashes and destroy all your valuable data, a computer crashing in the cloud should not affect the storage of your data.  if your personal computer crashes, all your data is still out there in the cloud, still accessible – In a world where few individual desktop PC users back up their on a regular basis, cloud computing is a data-safe computing platform!
  19. 19. Advantages of Cloud Computing  Universal document access: – That is not a problem with cloud computing, because you do not take your documents with you. – Instead, they stay in the cloud, and you can access them whenever you have a computer and an Internet connection – Documents are instantly available from wherever you are  Latest version availability: – When you edit a document at home, that edited version is what see when you access the document at work. – The cloud always hosts the latest version of your documents  as long as you are connected, you are not in danger of having an outdated version
  20. 20.  Easier group collaboration: – Sharing documents leads directly to better collaboration. – Many users do this as it is an important advantages of cloud computing  multiple users can collaborate easily on documents and projects  Device independence: – You are no longer tethered to a single computer or network. – Changes to computers, applications and documents follow through the cloud. – Move to a portable device, and your applications and documents are still available. Advantages of Cloud Computing
  21. 21. Disadvantages of Cloud Computing  Downtime  Security Risks  Vendor Lock-In  Limited Control
  22. 22. Conclusion Cloud Computing is a term that doesn’t describe a single thing-rather it is a general term that sits over a verity of services from infrastructure as a Service at the base, through Platform as a Service as a development tool and through to Software as a Service replacing on premise applications.
