The company I work for needs a big data service. in success always depends on yourself

My friend and I work in a company with hundreds of people and lately our manager has informed us that they have an excess in the information database and we have been commissioned to find a solution, she has given us a certain budget that we can use and He has told us to look for a solution, we were informing ourselves and we have seen that there is something called “big data” and it is just what we need, we need software of that type to handle so much data in a company like this, it is literally more than 15 tb of information, that’s why I want to ask you, does anyone know where to get a big data service?
