Computer scientists are a funny lot: hyperactive about the smallest problems and always eager to help – sometimes even going way beyond their limits of endurance.
After all, they’re working on things they like.
Still, the switch to cloud resources makes many “IT Guys” feel a bit queasy. After all, the company will no longer be running things on its own internally assembled server, but on a system in a data center with “shared resources” – things are different when you can actually touch the hardware.
Or are they?
Current developments, especially in IT, make it difficult for many computer scientists to set up a “home” in the new and “agile” cloud like the one in the company’s own data center.
They have already settled in their own data center: the hypervisor provides perfectly prepared images, containing a fine tuned set of configurations based on years of practical experience.
On the other hand, in Cloud environments it all looks like a shop. Prefabricated images correctly configured for the Cloud are already available – a feature that can lead to laziness. Accumulated, trained knowledge no longer comes into play.
Indeed, in the Cloud world some things function differently than before, so that research into “HOW?” can itself become a mammoth task in some scenarios.
Moreover, these images from the Cloud shop do not necessarily remain unchanged.
The shop images are patched and reconfigured. The shop itself and its user interface are growing and will continue to develop.
The new Cloud world changes rapidly.
The same goes for the data center “at home”, but in the past, you were on your own in dealing with patches for the storage units, the hypervisor, the switches, the routers and everything else.
That labor cost a lot of sweat and tears, but also established a sense of loyalty.
Cluster configurations across multiple data centers were and remain a great art. Configuration errors occur too frequently in manual operations.
So, there we are back at the beginning, with the years of experience and accumulated work that went into the configurations until we felt comfortable, and with ready-made images.
