SaaS: Microsoft Office 365, Salesforce.com, Google DocsSaaS facilitates running of online applications. The vendors completelymanage the applications while the users pay a ‘service’ charge. It is PaaS: Windows Azure, Google App Engine, Force.comsuitable only for generic applications and not for custom, complex ones. IaaS: Amazon Web Services, Rackspace, GoGrid, VMware,PaaS aprovides the platform to allow the creation of new web (cloud) CA Technologies, Bluemile.applications. Since moving applications between platforms is cumbersomethere is an increased risk of vendor lock-in. Vendors manage everything Explain the different cloud computing deployment modelsbut the applications. Public Clouds are available publicly (to ‘all’), owned and provisioned by aIaaS replaces a company’s infrastructure by allowing applications to run on cloud services vendor. A public cloud simply indicates shared resourcesthe vendor’s cloud hardware. The onus of managing the environment is available over the Internet from a third-party provider. These resources areequally shared between the user and the vendor. typically available on pay-per-use models.www.hexaware.com© Hexaware Technologies. All rights reserved.

What is multi-tenancy? Multi-tenancy is a technical mechanism in Cloud computing that supportsHybrid Clouds are a combination of the public and the private cloud. multi-tenants (i.e. customers) in the same operating environment. ItManagement responsibilities are equally shared between the vendor and ensures necessary isolation of customers’ privilege resources in a sharedthe enterprise itself. environment. A key characteristic for multi-tenancy is that one tenant’s data is effectively isolated from other tenants’ authorization.Cloud Computing Types Tenants can be from the same enterprise (e.g. finance and marketing departments of a single enterprise) and hence ‘multi-tenancy’ should not be used interchangeably with the term ‘multi-enterprise’.

  4. 4. What are the primary Pros and Cons of cloud based (or SaaS) BI? What are some of the scenarios where Cloud BI can be recommended?Pros: Cloud (SaaS) based BI can be recommended when:• Potential for faster deployments since little to no infrastructure is • You require lots of elasticity in terms of usage, price and volume required • You don’t need mission-critical SLAs• Scalability • You are not dependent on offline/disconnected architecture• Reduced total cost of ownership • You don’t need the maturity of on-premise BI platforms and solutions• Pay-on-demand• Reduction in carbon footprint due to no or limited hardware What are some of the risk mitigation steps and strategies to look into while adopting Cloud BI?Cons: • Perform due diligence for security, back up and disaster recoveryVendor ‘lock-in’ – Switching between cloud vendors • Do not overlook pricing and contract matters• Not suited for mission/machine critical apps where downtime cannot • Evaluate long term total cost of ownership (TCO) be afforded • Do not fail to test platforms through proof-of-concept programs• No or limited control • Check out support offerings like communities, discussion forums andWhy is cloud BI touted to be a game-changer? blogsThe use of BI in cloud makes it affordable and accessible to those who How do virtualization and private cloud initiatives impact BIneed it. Traditional BI systems have always been very expensive: right applications?from bringing up a system to maintaining it.

One of the central issues with ‘Big Data’ volume is the issue of how to most What are the other mega trends alongside Cloud BI?effectively store and analyze it, and in fact the cloud is ideal for this, which Today there are three mega trends: Cloud BI, Social media and Mobile BIis why companies like NetApp are beginning to offer hosted “near-IaaS” each feeding into the other. The reason these are inter-dependent isHadoop solutions that feature infrastructure optimized for I/O intensive because of what they can offer to the end user. For e.g. some of the keyanalytic workloads. advantages of Mobile BI are increased employee productivity, improved agility and enhanced collaboration. Social media offers real-time data thatAre portability options available with cloud vendors? can be crucial in making strategic business decisions at the right time.Today, it is fairly possible that businesses may get “locked in” with a cloud Cloud BI proves to be ‘the’ platform to tap the potential of the other twovendor. One of the important reasons for this situation is the fact that a mega trends to the fullest because of its great time-to-value, quick & cheapmajority of cloud vendors in the market have developed non-interoperable deployment, scalability and less to no administration requirements amongsolutions. This is a consequence of the fact that there are no others. When all the three mega trends work in tandem, the expectations ofinteroperability standards for cloud computing available today. today’s end-user can be easily met.Interoperability standards and frameworks for interoperating betweenclouds are still evolving and should become mature in the years to come.
