Cloud Computing

  1. 1. Presentation On 03/14/141 Prepared By Ramesh Sigdel MCIS Third Semester Roll No:-12818
  2. 2. Presentation Covered  What Is cloud computing?  Essential Characteristics (According to NIST)  How the Cloud is useful?  Do you Use the Cloud?  Types of Cloud  Service models  Advantages/Disadvantages  Security  Conclusion 03/14/14By:- Ramesh Sigdel2
  3. 3. What Is cloud computing?  The term “Cloud Computing” is being over used in last some years  Some defines narrowly as virtual services available over the internet, some go very broad, arguing anything you consume outside the firewall is in cloud (including conventional outsourcing)  This distinction among experts indicates that it is still somewhat of an evolving concepts 03/14/14By:- Ramesh Sigdel3
  4. 4. What Is cloud computing? Contd…  “Cloud” is used as a metaphor for “the internet” so cloud computing means a type of internet based computing  NIST 2011 – “Cloud Computing is a model for enabling ubiquitous (ever present), convenient, on-demand network access to a shared pool of configurable computing resources(e.g. networks, servers, storages, applications) that can be rapidly provisioned and released with minimal management effort of service provider interaction.” 03/14/14By:- Ramesh Sigdel 4
  5. 5. What Is cloud computing? Contd…  With this reference we can say – Cloud computing have the ability to be everywhere at once – Multiple people can have access to various computing resources as their requirements from any geographic distance. – According to NIST the cloud computing model is composed of five essential characteristics. 03/14/14By:- Ramesh Sigdel5
  6. 6. 03/14/14By:- Ramesh Sigdel6
  7. 7. Essential Characteristics  On-demand self service – It is a prime feature of most cloud providers – A consumer can provision computing capabilities such as server time and network storage as needed – the user accesses cloud services through an online control panel. – user can scale the required infrastructure up to a substantial level without disrupting the host operations. 03/14/14By:- Ramesh Sigdel7
  8. 8. Essential Characteristics  Broad Network access – Resources are available in N/w – Can be accessed through standard mechanism and promote heterogeneous platforms(mobile, tablets, laptops and workstations) – broad network access may not be deployed by many companies in a purely private cloud model. – is becoming more common in hybrid cloud settings. 03/14/14By:- Ramesh Sigdel8
  9. 9. Essential Characteristics (Contd…)  Resource pooling – Service provider’s resources are pooled to serve multiple consumers – Resources can be assigned and reassigned to the consumers as they demanded – users are not aware of the physical servers providing the resources. 03/14/14By:- Ramesh Sigdel9
  10. 10. Essential Characteristics (Contd…)  Rapid elasticity – Resources capabilities can be elastically provisioned and released – Edwin Schouten defines  Elasticity is basically a ’Rename’ of ‘scalability’ and removes any manual labor needed to increase or reduce capacity. 03/14/14By:- Ramesh Sigdel10
  11. 11. Essential Characteristics (Contd…)  Measured Services – Resources usage can be monitored, controlled, and reported by both user and administrator – users are able to see their own cloud usage – administrators can see the entire cloud usage – Generally done on pay-per-use or charge-per-use basis 03/14/14By:- Ramesh Sigdel11
  12. 12. How the Cloud is useful?  Traditional computer setup requires you to be in the same location as your data storage  Cloud makes possible to access your information from anywhere at any time  Especially helpful for business that cannot afford the H/w and storage space  You only need to pay for resources you will use 03/14/14By:- Ramesh Sigdel12
  13. 13. Do you Use the Cloud? 03/14/14By:- Ramesh Sigdel13
  14. 14. Do you use the cloud (Contd…) 03/14/14By:- Ramesh Sigdel14
  15. 15. Types of Clouds  Public Cloud – Computing infrastructure is hosted by cloud vendor at the vendors premises, and can be shared by various organizations. – Ultimate scalability – Cost effective – Utility style costing; public cloud services often employ a pay-as-you-go charging model  Avoid wasted capacity – Reliability; number of servers and networks involved – E.g. : Amazon, Google, Microsoft, Sales force 03/14/14By:- Ramesh Sigdel15
  16. 16. Types of Clouds (Contd…)  Private Cloud – The computing infrastructure is dedicated to a particular organization and not shared with other organizations, – only the specified client can operate – more expensive and more secure when compare to public cloud. – greater control and privacy. – Cost and energy efficiency in comparison to traditional LANs – E.g. : HP data center, IBM, Sun, Oracle, 3tera 03/14/14By:- Ramesh Sigdel16
  17. 17. Types of Clouds (Contd…) 03/14/14By:- Ramesh Sigdel17 Public Cloud Private Cloud Multiple Clients Hosted at providers Location Shared Infrastructures Access over Internet Low-Cost Single Clients Hosted at providers/Orgs Location Accessed over internet/Private N/w High Security High Cost
  18. 18. Types of Clouds (Contd…)  Hybrid Cloud – Organizations may host critical applications on private clouds. – where as relatively less security concerns on public cloud. – usage of both public and private together is called hybrid cloud. 03/14/14By:- Ramesh Sigdel18
  19. 19. Types of Clouds (Contd…) 03/14/14By:- Ramesh Sigdel19 You Got Public Cloud in my Private Network You Got Private Cloud in my Public Cloud
  20. 20. Service Models  Each providers serves a specific function, giving users more or less control depending on type  While choosing provider compare your needs to cloud services available  Cloud you require for personal use may vary than the cloud you require for your business  Cloud provider will be pay-as-you-go, you can purchase more resources as they are needed. 03/14/14By:- Ramesh Sigdel20
  21. 21. Service Models (Contd…) Mostly there are three service models of cloud  Software as a Service (SaaS)  Platform as a Service (PaaS)  Infrastructure as a Service (IaaS) 03/14/14By:- Ramesh Sigdel21
  22. 22. Service Models (Contd…)  Software as a Service-End User – also known as On-demand Service. – is an application that can be accessed from anywhere on the world as long as you can have an computer with an Internet Connection – We can access this cloud hosted application without any additional hardware or software. – E.g. : G-mail, Yahoo mail, Hotmail etc. – Also they can provide security features such as SSL encryption, a cryptographic protocol. 03/14/14By:- Ramesh Sigdel22
  23. 23. Service Models (Contd…)  Platform as a Service-Application Developers – Give us nice API (Application Programming Interface) and take care of the implementation. – In the PaaS model, cloud providers deliver a computing platform and/or solution stack typically including operating system, programming language execution environment, database, and web server. – is a platform for developers to develop their own applications, which means rapid development at low cost – E.g. Salesforce.com, Windows Azure etc. 03/14/14By:- Ramesh Sigdel 23
  24. 24. Service Models (Contd…)  Infrastructure as a Service-Network Architect – also known as hardware as a service. – is a computing power that you can rent for a limited period of time. – allows existing applications to be run on a cloud suppliers hardware. – cloud providers offer computers – as physical or more often as virtual machines – raw (block) storage, firewalls, load balancers, and networks 03/14/14By:- Ramesh Sigdel24
  25. 25. Service Models (Contd…) 03/14/14By:- Ramesh Sigdel25 Cloud Clients Web browsers, mobile app, thin client, terminal emulator, … SaaS CRM, Email, virtual desktop, communication, games, … PaaS Execution runtime, database, web server, development tools, … IaaS Virtual machines, servers, storage, load balancers, network, …
  26. 26. Advantages of Cloud Computing  Instant, flexible, pay-per-use.  No contracts, usage based, no upfront cost  Rent based on used only  Echo friendly  We can reduce E-waste by using Cloud Computing i.e. by Infrastructure as a Service (IaaS). 03/14/14By:- Ramesh Sigdel26

  28. 28. Disadvantages of Cloud Computing  Cloud computing is impossible if you cannot connect to the Internet.  Since you use the Internet to connect to both your applications and documents, if you do not have an Internet connection you cannot access anything, even your own documents  When you are offline, cloud computing simply does not work  Security and Privacy 03/14/14By:- Ramesh Sigdel28
  29. 29. Security  Methods of encryption  Will they have backup of data  Do they have firewall setup 03/14/14By:- Ramesh Sigdel29
  30. 30. Conclusions  Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort of service provider interaction. 03/14/14By:- Ramesh Sigdel30
  31. 31. Conclusions (Contd…)  It opens up the world of computing to the broader range of usages and increases the ease of use (through internet)  You must be aware of the security risk of having data stored on the cloud, it can be accessed through an unsecured internet connection 03/14/14By:- Ramesh Sigdel31
