We have nine servers that use Amazon for hosting.
We migrated from on-premise to the Hawaii Amazon cloud. We migrated from enhanced package saving to enhanced package pay. We also changed our database provider from the IBM Db2 Tools database. Now we use the HANA database, which provides more memory. Previously, memory was around four to six gigabytes of RAM. Now, they have 300 gigabytes of RAM. HANA's database technology can provide hosting on memory alone. There is no need to install a hard disk. The actual performance creates a memory, not the processor.
AWS is famous for the stability of its cloud hosting, but we faced some challenges. When we wanted to import the image or server on Amazon, we could not import the server. Amazon's old server like VMware is a VM machine or a central machine. We could not download the central machine on-premise.
We fixed this challenge. We can now tell when we lose an image from AWS VMware or an AWS image from our server on AWS. I think this is back in AWS. We couldn't download VM or our server on-premise before.
