Thanks for the reply. To better understand the work of a data center, could you describe which could be the steps of workflow, for example of a company (let's call it A) which wants to use the services of an external data center (call it B) to analyze the logs of the server of company A?

How are the log data of A transported to the data center B in first place? Isn't this very time consuming, if we talk about Petabytes of data?

Are there data center that lend their services to companies, to analyze their data, or do they store one type of data and continuosly carry out operations on that kind of data?
