9. Cloud Computing can be defined as “a type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service level agreements established through negotiation between the service providers and consumers.” www.mayankagr.in Twitter: @mayankcloud

17. Types Of Cloud www.mayankagr.in Twitter: @mayankcloud

18. Private/Enterprise Clouds Public/Internet Clouds 3rd party, multi-tenant Cloud infrastructure & services: * available on subscription basis Cloud model run within a company’s own Data Center / infrastructure forinternal and/or partners use. Cloud Deployment Models Hybrid/InterClouds Mixed usage of private and public Clouds: Leasing publiccloud serviceswhen private cloud capacity is insufficient www.mayankagr.in Twitter: @mayankcloud

19. Types Of Cloud • Public : Public clouds are made available to the general public by a service provider who hosts the cloud infrastructure. Generally, public cloud providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet. With this model, customers have no visibility or control over where the infrastructure is located. • Private : Private cloud is cloud infrastructure dedicated to a particular organization. Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment.  It is not shared with other organizations, whether managed internally or by a third-party, and it can be hosted internally or externally. www.mayankagr.in Twitter: @mayankcloud

20. Continued… • There are two variations of private clouds: • On-Premise Private Cloud: This type of cloud is hosted within an organizations own facility. A businesses IT department would incur the capital and operational costs for the physical resources with this model. On-Premise Private Clouds are best used for applications that require complete control and configurability of the infrastructure and security. • Externally Hosted Private Cloud:  Externally hosted private clouds are also exclusively used by one organization, but are hosted by a third party specializing in cloud infrastructure. The service provider facilitates an exclusive cloud environment with full guarantee of privacy. This format is recommended for organizations that prefer not to use a public cloud infrastructure due to the risks associated with the sharing of physical resources. www.mayankagr.in Twitter: @mayankcloud

21. Continued… • Hybrid: Hybrid Clouds are a composition of two or more clouds (private, community or public) that remain unique entities but are bound together offering the advantages of multiple deployment models. In a hybrid cloud, you can leverage third party cloud providers in either a full or partial manner; increasing the flexibility of computing. Augmenting a traditional private cloud with the resources of a public cloud can be used to manage any unexpected surges in workload.  • Here are a couple of situations where a hybrid environment is best: • Your company wants to use a SaaS application but is concerned about security. • Your company offers services that are tailored for different vertical markets. You can use a public cloud to interact with the clients but keep their data secured within a private cloud. • You can provide public cloud to your customers while using a private cloud for internal IT. www.mayankagr.in Twitter: @mayankcloud

28. Welcome to the New World of Cloud Computing www.mayankagr.in Twitter: @mayankcloud

29. Why Cloud Computing • Reduction of costs – unlike on-site hosting the price of deploying applications in the cloud can be less due to lower hardware costs from more effective use of physical resources. • Universal access - cloud computing can allow remotely located employees to access applications and work via the internet. • Up to date software - a cloud provider will also be able to upgrade software keeping in mind feedback from previous software releases. www.mayankagr.in Twitter: @mayankcloud

30. Continue… • Choice of applications.  allows flexibility for cloud users to experiment and choose the best option for their needs. Cloud computing also allows a business to use, access and pay only for what they use, with a fast implementation time. • Potential to be greener and more economical - the average amount of energy needed for a computational action carried out in the cloud is far less than the average amount for an on-site deployment. • Flexibility – cloud computing allows users to switch applications easily and rapidly, using the one that suits their needs best. www.mayankagr.in Twitter: @mayankcloud
