Runtimes Everything except Completely Networking the applications is managed Cloud computing can be defined as a solution in which all users share the Storage managed by the vendor by the vendor Vendor managed available resources as and when needed. It can be identified by some Server Hardware characteristics such as elasticity (i.e. the capability to scale up or down on Virtualization demand), multi-tenancy, pay-per-use etc. Servers What is Software-as-a-Service (SaaS), Platform-as-a-Service Provide major SaaS, PaaS and IaaS vendors in the market (PaaS) and Infrastructure-as-a-Service (IaaS)? SaaS: Microsoft Office 365, Salesforce.com, Google Docs SaaS facilitates running of online applications. The vendors completely manage the applications while the users pay a ‘service’ charge. It is PaaS: Windows Azure, Google App Engine, Force.com suitable only for generic applications and not for custom, complex ones.

What is multi-tenancy? Multi-tenancy is a technical mechanism in Cloud computing that supports Hybrid Clouds are a combination of the public and the private cloud. multi-tenants (i.e. customers) in the same operating environment. It Management responsibilities are equally shared between the vendor and ensures necessary isolation of customers’ privilege resources in a shared the enterprise itself. environment. A key characteristic for multi-tenancy is that one tenant’s data is effectively isolated from other tenants’ authorization.

  • 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 recovery Vendor ‘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 and Why is cloud BI touted to be a game-changer? blogs The use of BI in cloud makes it affordable and accessible to those who How do virtualization and private cloud initiatives impact BI need it. Traditional BI systems have always been very expensive: right applications? from bringing up a system to maintaining it. Also, the users who needed BI is all about agility and clearly technology such as cloud that enables these BI systems had no access, leaving them incapable of taking any important technology such as BI to improve business agility is very critical business decisions. With cloud BI, the cost drops dramatically with important. Cloud provides a new delivery channel for firms to get their BI a web browser being the primary or the only requirement in most cases. It services more cheaply than the typical seven-figure BI/DW and data also renders better support to dashboards or reports intended for the next integration deal.

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 BI is why companies like NetApp are beginning to offer hosted “near-IaaS” each feeding into the other. The reason these are inter-dependent is Hadoop 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 key analytic workloads. advantages of Mobile BI are increased employee productivity, improved agility and enhanced collaboration. Social media offers real-time data that Are 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 two vendor. 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 & cheap majority of cloud vendors in the market have developed non-interoperable deployment, scalability and less to no administration requirements among solutions. This is a consequence of the fact that there are no others. When all the three mega trends work in tandem, the expectations of interoperability standards for cloud computing available today. today’s end-user can be easily met. Interoperability standards and frameworks for interoperating between clouds are still evolving and should become mature in the years to come. How is data loaded into a cloud-based data warehouse? Loading data into a cloud-based data warehouse is no different from how it Why should traditional BI vendors adopt Cloud BI when it works in any on-premise DBMS. Once a schema is defined, the data can jeopardizes their revenues from selling licenses? be extracted and transferred using standard migration tools available with Traditional BI vendors can and would welcome Cloud BI; they just have to the vendor.

Basically, the model changes from earning big with few companies to earning small with many companies. The upside to this approach is that it increases their market presence since their clientele would be spread all across from small, medium to major enterprises. www.hexaware.com © Hexaware Technologies.
