I think it depends over your existing system. If you are habitual of playing with huge clusters of data then it might be easy for you to manage the space to store the huge amount of data. What you exactly need is just the right tool at right place to analyze and process the data. In order to derive the results, you need to hire data scientists. There is no doubt that big data is highly capable to derive the graphical and visualized analytical results for you mining the data that is unstructured and hard to be managed by your traditional database systems.
Analysis of Big Data including the data the type of data that have not been analyzed before, offers the deep level of insight to what are customers trends and the business operations. The potential payoffs are enabling customer retention, sale of products, high quality production and lower rates of return. As the market is growing, small enterprises and large businesses, both are adopting the Big data technology without any blink of an eye. And according to me business is subjected to risk, so don't worry just invest your resource over the right business intelligence tool. I assure you that big data can really improve the bottom line that impact the overall profitability. Everything is the same, just the basic difference is that big data is the new data source that has not been collected, captured, structured, analyzed and scrutinized before. While the core advantage you notice is that the large volumes of data are not necessary to be found structured and managed that makes it impossible to be managed by traditional data base system, creating a challenge.
If you are using any traditional database management system, the business intelligence tools is quite new things to you. But you will have to adapt the change at any point of time. I recommend you to analyze your business requirement and try to scale up you business, if it is possible. And in case you need a big shift to the technology, take suggestion from experienced IT professionals and big data service provider. Hire a data scientists and integrate your existing system with the any big data tool of your choice. Hope you understand my point.
