My point is that i want to switch from physical and in-house servers to cloud computing because investing in this new technology has many advantages for business management in term of work effectiveness and management cost .However; since I have read some stuff about security in the cloud computing blog , i become somewhat doubtful to invest mainly when i experienced a data storage crash with a cloud company that i do not want to name , so to what extent cloud computing is safe enough for data base storage and web hosting in term of privacy and backup safety .and which are the best reliable companies affording quality services .
