What is Cloud Computing?
Cloud computing really is accessing IT resources Like Data Storage and Application services Like Business Intelligence, ERP, CRM needed to perform functions with dynamically changing needs using a web browser or a lightweight application installed in a desktop.
A Business user or IT developer requests access from the cloud rather than an Application Installed in Local Machine or Server owned by an organization.
Different Models in Cloud Computing
•Infrastructure-as-a-Service (IaaS)- is all about hardware, data storage, networking and bandwidth
•Platform-as-a-Service (PaaS)- OS + Application Server Stack like .Net framework, VS.Net, SQL Server
•Software-as-a-Service (SaaS)- is simply order an application & start consuming in minutes
Data warehouse and Cloud computing
Data warehouse in the cloud is primarily an infrastructure design (IaaS) option as a data model must still be developed, an integration strategy must be deployed and BI user access must be enabled and managed.
Private clouds are an emerging infrastructure design choice for some organizations in supporting their data warehouse and analytics.
BI Vendors in Cloud computing
ETL tool vendor like Informatica has come up with The Informatica Cloud. It consists of Informatica Cloud Secure Agent which is a lightweight program to be installed in the Local PC (Windows/Linux).
Web browser can be used to access the Informatica Server in the cloud (Informatica Cloud) .
The source system can be either in the Premise or in the cloud (example Salesforce.com ) and target can be a database in premise .Data is not staged in the Informatica Cloud and only data transformation is done in the cloud and loaded into target Server which may be located in the Company premise
Third-party providers, such as Elastra and RightScale, have created sophisticated dashboards and management tools around these BI services, offering world class tools for deploying and managing virtualized data center.
Future of BI Cloud computing
Actual numbers vary but the general consensus is that the Business Intelligence (BI) and Analytics in the cloud is a fast growing market. IDC expects a compounded annual growth rate (CAGR) of 22.4% through 2013. This growth is primarily driven by two kinds of SaaS applications. The first kind is a purpose-specific analytics-driven application for business processes such as financial planning, cost optimization, inventory analysis etc. The second kind is a self-service horizontal analytics application/tool that allows the customers and ISVs to analyze data and create, embed, and share analysis and visualizations.
