Development to do....

• It have to be use AWS Service. for the EC2, S3, RDS.
• Multer-extended Library is so useful, but it can's cover the lastest Nest.js version.
  Need to find other multi file upload library.
• The data from Front-end is not a Encryption. It's week for Hacking. Need to Change data transport.
• If use Multer-extended uploading .img .mp4 .mp3 ... files need to check capacity problem. and Temp file System.
• There login system need to change PKI system.
