We know we need to create data warehouse in order to analyse we need to find granularity but can we really do when there is huge explosion of data from cloud think like data from youtube,twitter, facbook and devices, geolocations etc….no..Skill set required for future cloud BI , webservices ,SOA and app developement converge and with that also security.
Can we really afford Extract , transform , load cycles in cloud.With huge data needs to migrated and put in cloud for analysis not exactly.
ETL will remain valid for Enterprise all but kind of applications like social Applications ,cloud computing huge data we have alternative sets of technology which start emerging Hadoop , Hive ,HBase are one such but we cannot even afford these when data is really huge.We can relie on analytics to predict and data mine to find trends.But these assumptions are also based on models. The mathematical model we think based on evaluation we start working on implementing and hence predicting trends but what id model we thought was not the right model may be right 40% time and ignoring 60% or rigt always but set it beleived changed over period of time..I cloud we have 3V, volume : huge volume of data,
Variety: huge variety of data from desperate sources like social sites, geo feeds,video,audio, sensor networks.
Velocity: The data comes up really fast always we need to analyse the lastest voulme of data. Some may get tera byte data in day may need to analyse only that data..like weather applications, some many need months data, some week etc..
So we cannot model such variety and velocity and vloume in traditional datawarehouses.So one size fits all is not solution. So can we maintain multiple sets of tools for each data analytics, ETL, CDI, BI, database model, data mining etc…etc.. Are we not going to miss many aspect of problem when intersection between these was required.My guess is yes currently
Also we need to integrate everything to web and web to everything and integrate each other so web services come in handy.And when we need to present this over cloud so that’s where all cloud technologies set in.So convergence of BI,SOA,Application development and cloud technology is inevitable. As all cloud apps will require input and output and presentations from BI,SOA,data mining, analytic etc. Already we see hadoop as system which is mixture of Java and data warehouse BI,web services, cloud computing,parallel programming.
What about security it will be most important characteristic o which cloud will be based.? Already we have lots of cloud analytics security products based on analysis from cloud.We have IAM is most important in cloud. Identity and Access management. Increasingly applications and apps require data from IAM and from network stack keep increasing driving them closer…SAAS, and PAAS this going to be most important characteristics.
