Cloud computing
- 1. Cloud computing is an on-demand service model for IT provision, often based on virtualization and distributed computing technologies. Cloud computing architectures have: •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)

- 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.
- 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. 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. Hybrid Cloud A hybrid infrastructure takes advantage of both public and private clouds: Services provided over the Internet—the public cloud Services provided by the enterprise data center—the private cloud
- 16. •The actual term "cloud" borrows from telephony in that telecommunications companies, who until the 1990s offered primarily dedicated point-to-point data circuits, began offering Virtual Private Network (VPN) services with comparable quality of service but at a much 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 described his visions of an “intergalactic computer network” •In 1969 and computer scientist Jon McCarthy who said back then that "computation may someday be organized as a public utility". •Oracle presented its idea of a thin client Network Computer, known as NC, in 1996, revived the idea in 1999 when it announced that it would actually build the device and sell it for $200. •Current cloud computing started with the introduction of Amazon Web Services (AWS) in 2006. •Google has also been a driving force in giving cloud computing a much more visible face, especially though its popular cloud web backed applications.
- 17. Our experience with application platforms today comes mostly from on-premises platforms. A useful way to think about cloud platforms is to see how the services an application developer relies on in the on premises environment translate to the cloud. For on-premises infrastructure services, typical examples include the following: •Storage •Integration •Identity FROM ON-PREMISES PLATFORMS TO CLOUD PLATFORMS
- 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. 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. 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. Why CHEMOIL needs cloud computing (in PaaS)? Using the traditional on-premises model, how will the company proceed with the development 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 web apps (Because in real-time scenario there are a few more servers like test, staging and production)
- 22. Cloud based PaaS Now you don’t need to invest millions of dollars to get that project environment ready for your developers. The PaaS provider will deliver the platform on the web, and in most cases you can consume the platform using your browser. There is no need to download any software. This combination of simplicity and cost efficiency empowers small and mid-size companies, or even individual developers, to launch their own Cloud SaaS. Without any initial investment, they can leverage the power of these platform providers. PaaS Layers •Cloud OS •Cloud Middleware Google 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. USING CITRIX AS A PLATFORM (PaaS) FOR WAN OPTIMIZATION •Cloud computing is a major trend enabling more efficient, flexible and green IT for remote offices and Mobile users. •Citrix is the leading technology supporting this trend. However this shift of computing paradigm loads more data onto the associated WAN, which at the same time must become more responsive •Opteq has developed an intelligent solution to compliment Citrix deployments; with one Opteq unit in the data centre the network is fully optimised for all network traffic, the Citrix users consistently experience ‘LAN’ levels of performance at remote locations and costly WAN upgrades are avoided. Additional units can be deployed at large remote locations that both offload and thus enhance the Citrix servers and further accelerate applications.

- 27. SaaS, PaaS, & IaaS migration 1) 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 proposition 2) 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 processes 3) 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. The concept of cloud computing can be very effectively implemented in Chemoil. Few disadvantages can be overcome with a suitable application developed by other major companies or Chemoil itself can develop a suitable application or we can use some utility tools that make our data compatible. The major advantage is that the performance of the network can be effectively increased to 5%-25% with cloud computing. We need not change the other applications and working environments instead we can use compatible platform such as citrix or windows azure. Comparing with the infrastructure of the company we can adopt a suitable platforms to enhance the network and its capabilities
