Cloud computing

  1. 1. Cloud computing is an on-demand service model for IT provision, often based onvirtualization and distributed computing technologies. Cloud computing architectureshave:•highly abstracted resources•near instant scalability and flexibility•near instantaneous provisioning•shared resources (hardware, database, memory, etc)•‘service on demand’, usually with a ‘pay as you go’ billing system•programmatic management (e.g., through WS API)
  2. 2. Why we call “Cloud computing” Cloud
  3. 3. Common Attributes of Cloud Computing• Pooled computing – advanced virtualization• Delivered over the Internet• Elastic scaling• Flexible pricing – pay only for they use• Provide resources as a service
  4. 4. Common Attributes of Cloud Computing• Pooled computing – advanced virtualization• Delivered over the Network• Elastic scaling• Flexible pricing – pay only for they use• Provide resources as a service
  5. 5. Common Attributes of Cloud Computing• Pooled computing – advanced virtualization• Delivered over the Internet• Elastic scaling• Flexible pricing – pay only for they use• Provide resources as a service
  6. 6. Common Attributes of Cloud Computing• Pooled computing – advanced virtualization• Delivered over the Internet• Elastic scaling• Flexible pricing – pay only for they use• Provide resources as a service
  7. 7. Common Attributes of Cloud Computing• Pooled computing – advanced virtualization• Delivered over the Internet• Elastic scaling• Flexible pricing – pay only for they use• Provide resources as a service
  8. 8. The LAYERS are broadly divided into threecategories:• Infrastructure-as-a-Service (IaaS)• Platform-as-a-Service (PaaS)• Software(application)-as-a-Service (SaaS)
  9. 9. Cloud Service Layers - Containing Software as a Collaboration Business Processes Service (SaaS) Industry Applications CRM/ERP/HR Platform as a Middleware Web 2.0 Application Runtime Service (PaaS) Development Tooling Database Java RuntimeInfrastructure as Servers Networking Storage Data Center Fabric a Service (IaaS) Shared virtualized, dynamic provisioning
  10. 10. Cloud Service Layers - Example Software as a Service (SaaS) Platform as a Service (PaaS)Infrastructure as a Service (IaaS)
  11. 11. A cloud can be classified as •Public cloud is the most common and popular form of cloud computing and the type most of us tend to think about when we talk about cloud computing. In a public cloud, computing resources are dynamically provisioned over the Internet. A third party service such as “utility” and invoices its subscribers based on the use of computing resources. •Private cloud is delivered to a restricted set of customers (one or multiple customers). In this case, a cloud infrastructure is often maintained for a specific organization. Private clouds can be maintained on or off the premises of the organization that accesses it. •Community cloud is a cloud environment in which multiple organizations access the infrastructure based on similar needs. Community clouds are a compromise between private and public clouds, with typically more available resources than a public cloud, but less cost than a private cloud with just one subscriber. Community clouds are often used by a number of departments within large organizations, including governments.
  12. 12. Cloud Implementation Type
  13. 13. Private Cloud• Owned and managed by the enterprise• Limits access to enterprise and partner network• Retains high degree of control, privacy and security• Enables business to more easily customize service• Accessed from "inside" the firewall
  14. 14. Public Cloud• Owned and managed by service provider• Delivers select set business process, application or infrastructure services on a “pay per use” basis• Highly standardized• Limited customization options• Accessed from "outside" the firewall
  15. 15. Hybrid CloudA hybrid infrastructure takes advantage of both public andprivate clouds: Services provided over the Internet—the public cloud Services provided by the enterprise data center—the private cloud
  16. 16. •The actual term "cloud" borrows from telephony in thattelecommunications companies, who until the 1990s offered primarilydedicated point-to-point data circuits, began offering Virtual PrivateNetwork (VPN) services with comparable quality of service but at amuch lower cost.•The idea of cloud computing is not new.•The concept can be traced back to two sources in the 1960s -J.C.R Licklider, one of the pioneers of the ARPANET, who describedhis visions of an “intergalactic computer network”•In 1969 and computer scientist Jon McCarthy who said back thenthat "computation may someday be organized as a public utility".•Oracle presented its idea of a thin client Network Computer, knownas NC, in 1996, revived the idea in 1999 when it announced that itwould actually build the device and sell it for $200.•Current cloud computing started with the introduction of Amazon WebServices (AWS) in 2006.•Google has also been a driving force in giving cloud computing a much morevisible face, especially though its popular cloud web backed applications.
  17. 17. Our experience with application platforms today comesmostly from on-premises platforms. A useful wayto think about cloud platforms is to see how the servicesan application developer relies on in the on premisesenvironment translate to the cloud.For on-premises infrastructure services, typical examplesinclude the following: •Storage•Integration•Identity FROM ON-PREMISES PLATFORMS TO CLOUD PLATFORMS
  18. 18. SaaS Pro & Cons Benefits Challenges• Speed • Extension of the security model• Reduced up-front cost, potential to the provider (data privacy for reduced lifetime cost and ownership)• Transfer of some/all support • Governance and billing obligations management• Elimination of licensing risk • Synchronization of client and• Elimination of version vendor migrations compatibility • Integrated end-user support• Reduced hardware footprint • Scalability
  19. 19. PaaS Pro & Cons Benefits Challenges• Pay-as-you-go for development, • Governance test, and production • Tie-in to the vendor environments • Extension of the security model• Enables developers to focus on to the provider application code • Connectivity• Instant global platform • Reliance on 3rd party SLA’s• Elimination of H/W dependencies and capacity concerns• Inherent scalability• Simplified deployment model
  20. 20. IaaS Pro & Cons Benefits• Systems managed by SLA should equate • Challenges to fewer breaches • Portability of applications• Higher return on assets through higher • Maturity of systems management utilization tools• Reduced cost driven by ▫ Less hardware • Integration across Cloud boundary ▫ Less floor space from smaller • Extension of internal security models hardware footprint ▫ Higher level of automation from fewer administrators ▫ Lower power consumption• Able to match consumption to demand
  21. 21. Why CHEMOIL needs cloud computing (in PaaS)?Using the traditional on-premises model, how will the company proceed with thedevelopment if they want to develop it in say ASP.Net with a SQL Server database?They will need to•Procure VS.Net developers license.•Procure SQL Server licenses.•Procure 3rd party tools (reporting etc) licenses.•Develop and then deploy on a production server on a fixed budget.Though the above steps are costly and complicated yet they apply only to simple webapps (Because in real-time scenario there are a few more servers like test, staging andproduction)
  22. 22. Cloud based PaaSNow you don’t need to invest millions of dollars to get that project environment readyfor your developers. The PaaS provider will deliver the platform on the web, and inmost cases you can consume the platform using your browser. There is no need todownload any software. This combination of simplicity and cost efficiency empowerssmall and mid-size companies, or even individual developers, to launch their ownCloud SaaS. Without any initial investment, they can leverage the power of theseplatform providers.PaaS Layers•Cloud OS•Cloud MiddlewareGoogle App Engine and Windows Azure are examples of Cloud Operating Systems (OS). OrangesScape and Wolf PaaS are cloud middleware. Google App Engine and Windows Azure
  23. 23. USING CITRIX AS A PLATFORM (PaaS) FOR WAN OPTIMIZATION•Cloud computing is a major trend enabling more efficient, flexible andgreen IT for remote offices and Mobile users.•Citrix is the leading technology supporting this trend. However this shiftof computing paradigm loads more data onto the associated WAN, whichat the same time must become more responsive•Opteq has developed an intelligent solution to compliment Citrixdeployments; with one Opteq unit in the data centre the network is fullyoptimised for all network traffic, the Citrix users consistently experience ‘LAN’levels of performance at remote locations and costly WAN upgrades areavoided. Additional units can be deployed at large remote locations that bothoffload and thus enhance the Citrix servers and further accelerateapplications.
  24. 24. Wan Optimization Technology •Host Pacing •Queue Elimination •True QoS •Fair Share •Traffic Prioritization •TCP Window Scaling •UDP Rate Control •Extended MPLS •Latency and Jitter Management •Flow Optimization •Network Balancing •Network Management and Reporting

  27. 27. SaaS, PaaS, & IaaS migration1) SaaS ▫ Easy first step to adopt alternative desktop office application ▫ Requires nothing more than a credit card to start with ▫ Will drive home the SOA value proposition2) PaaS • Aimed primarily at small & new companies but models apply to all • Large companies will benefit as services scale up and model is driven into internal software development tools and processes3) IaaS • New approach to Utility Computing • Scale using external provider to avoid cap-ex of peak demand • Longer term play due to immature tools and resistance to change

  43. 43. The concept of cloud computing can be very effectively implementedin Chemoil. Few disadvantages can be overcome with a suitableapplication developed by other major companies or Chemoil itself candevelop a suitable application or we can use some utility tools thatmake our data compatible. The major advantage is that the performance of the network can beeffectively increased to 5%-25% with cloud computing. We need notchange the other applications and working environments instead wecan use compatible platform such as citrix or windows azure.Comparing with the infrastructure of the company we can adopt asuitable platforms to enhance the network and its capabilities
