Cloud computing

  2. 2. WHAT IS CLOUD COMPUTING? Cloud computing is a style of computing where applications and files are hosted on a “cloud” consisting of thousands of computers and servers all linked together and accessible via the internet. Cloud is a large group of interconnected computers which could be personal computers or network servers. Any web based application or service offered via cloud computing is called a cloud service. Cloud services can include anything from calendar and contact applications to word processing and presentations. Everything you do with cloud computing is web- based instead of being desktop-based.3/6/2013 2
  3. 3. WHAT CAN CLOUD SERVICES DO FOR YOU ? Listen to your favorite music. Host a web conference. Find your driving directions. Make phone calls on the web. Read news and answer emails. 3/6/2013 3
  4. 4. GRID COMPUTING Vs CLOUD COMPUTING Grid computing is a form of computing in which a single large task is broken into several small tasks through a distributed system on multiple computer networks. Grids are usually owned by an organization on its premises. Cloud computing has evolved from the grid computing utility model that implements a virtual supercomputer made up of a cluster of networked or internetworked computers acting in unison to perform very large tasks. The cloud servers are located in physically disparate locations.3/6/2013 4
  5. 5. TYPES OF CLOUD SERVICES Software as a Service(SaaS). Platform as a Service.(PaaS). Infrastructure as a Service(IaaS).3/6/2013 5
  6. 6. SOFTWARE AS A SERVICE(SaaS) SaaS is a model in which the vendors host the application on the internet that is commonly accessible to clients upon subscription. In SaaS business model, the software is hosted on the web and the customers do not have to bear the upgradation & maintenance costs as the vendors do everything such as patching, upgradation and keeping the infrastructure running.3/6/2013 6
  7. 7. SOFTWARE AS A SERVICE(SaaS) Cisco WebEx: Web conferencing software that is available to clients on subscription model. OpenChannel: Banking SaaS solution for online banking and bill payment functionality across multiple channels.3/6/2013 7
  8. 8. SOFTWARE AS A SERVICE(SaaS)Many high powered applications that the customersneed for their everyday business operations arecurrently being offered through SaaS model.Customer Relationship Management(CRM).Web Conferencing.Supply Chain Management(SCM).Human Resources Management(HRM).Enterprise Resource Planning(ERP).Enterprise Risks Management(ERM).3/6/2013 8
  9. 9. PUBLIC Vs PRIVATE Vs HYBRID CLOUDS Clouds services can generally be classified into 3 broad categories depending on the owner of the cloud data centers . Public Clouds. Private Clouds. Hybrid Clouds. 3/6/2013 9
  11. 11. BENEFITS OF CLOUD COMPUTING Lowers IT infrastructure costs . Increased computing power. Few maintenance issues. Instant software updates. Easier group collaboration. Universal access to documents. Intelligent computing. Consistent performance monitoring . Affordable price for use.3/6/2013 11
  12. 12. RISKS ASSOCIATED WITH CLOUD COMPUTING Security concerns with private data. Quality of cloud service. Data migration . Standardization in technology. Reliability of cloud service.3/6/2013 12

  18. 18. FIVE PROFIT CONCERNS DRIVING BUSINESS TO THE CLOUD. Cloud computing enables reduction in capital expenses on internal infrastructure. Cloud based variable cost model reduces the financial risks as it automatically scales up and down with the volume of business. In-house systems can be migrated to the cloud with relative ease if the process is well designed. Cloud computing is priced very competitively for customers and the customers pay on consumption basis like utilities. It „s attractive to most businesses as it allows them to focus most on their customers, business processes and employees.3/6/2013 18
  19. 19. IMPACT OF CLOUD COMPUTING Professional services will be bundled with commodity cloud services. Large IT -enterprises will deliver cloud services as part-time cloud vendors. Cloud computing will unleash further innovations in many arenas of everyday business. Local constraints on energy costs and capacities, space requirements for IT infrastructure, and up-front investment costs would be reduced significantly. Barriers to Security & Compliance perception would disappear over time. Simplification of the overall information technology landscape would be possible in the foreseeable future..3/6/2013 19
  20. 20. COMMON TRAITS OF CLOUD SERVICES Low barriers to entry and easily accessible to small enterprises. Large scalability options . Multitenancy (many users share the resources). Device independence(Users access the systems on different hardware).3/6/2013 20
  21. 21. COMPONENTS OF CLOUD SERVICEClients:The devices that the end users interact with to manage their information onthe cloud.Eg. Laptops,Desktops,Tablet computers, Mobile phones or PDAs.Datacenters:Refers to the collection of servers where the application is housed andavailable to the clients upon subscription.Distributed Servers: Servers that are in geographically disparatelocations which give the service provider more flexibility in options andsecurity. 3/6/2013 21
  22. 22. THREE COMPONENTS OF CLOUD SOLUTION Internet Data centersClient computers Distributed servers 3/6/2013 22
  23. 23. BENEFITS OF SaaS BUSINESS MODEL Huge cost savings for the clients as they pay based on subscription and no upfront investments for IT infrastructure. Barriers to marketing is few as the applications are available on the web for a large clientele. Clients could access their applications through secure socket layers without complex back-end configurations. Obviates the need for a large number of in-house IT staff for business. Helps protect the intellectual property rights of vendors.3/6/2013 23
  24. 24. INFRASTRUCTURE AS A SERVICE(IaaS). IaaS model is based on the assumption that the vendors make available resources such as server space, network equipments,memory,CPU cycles, and storage space for the clients which can be scaled up and down depending on the needs of the clients. The clients simply pay for the service as subscription fees on contractual basis in stead of owning such IT infrastructure.3/6/2013 24
  25. 25. PLATFORM AS A SERVICE( PaaS) PaaS model is based on the assumption that all the resources required to build applications and services are made available on the web by the vendors and the clients do not need to download or install such software on their PCs.3/6/2013 25
  26. 26. CORPORATE APPLICATIONS OF CLOUD COMPUTING Five major areas where corporations would find cloud services extremely useful. Online planning, scheduling and managing tasks. Collaborating on customer relationship management. Collaborating on project management. Collaborating on Budgets. Collaborating on presentations.3/6/2013 26

  32. 32. CONCLUDING THOUGHTSThe power of super-computing would be accessible to the masses for variousfunctionalities such as accounting, financial service, healthcare service andhuman resources as a real-time service through cloud computing..The best bet for the companies is to explore the new opportunities of cloudcomputing with an open mind in order to assess its relative strengths andweaknesses as a stand-alone technology implementation.As the technology is now in infancy, with progress of time ,wide spread applicationsof this technology would be possible through standardization before it becomes amainstream method of computing for the masses.Cloud computing would be the economic engine of growth for many startups formeeting their IT needs in everyday business operations.An ultimate ISO standard would emerge in order to ensure the best quality ofcloud services on the web in the foreseeable future. 3/6/2013 32
