This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
Merging SDWAN and Cloud
When I was a young man in the nineties my first job was working for the railways a a programmer on DB2 using COBOL and embedded SQL. I used a Big Iron. I worked for the biggest transportation company in South Africa
at the time, and we could afford those IBMs and Amdahls. Other
companies used computer bureaus. Computer bureaus would buy a mainframe
or a mid-rand UNIX
system and lease out time to clients. To connect to these mainframes
and mid-range systems we used POTS. This was either a dial-up or a
permanently nailed up link that relied mostly on 2400 baud serial based
communications. To achieve these low speeds we did not use any fancy
pants graphical interfaces but optimised green screens. In reality it
was Cloud version 0.9!
