Introduction In the old days we had physical servers with 1 OS to 1 box, then virtualisation was invented, giving higher consolidation.
There is quite a lot of waste with VMs, as each has their own RAM, disk space etc, lots of technologies have been invented to reduce this (de-duplication of storage & memory, linked clones etc).
The big advantage with containers is sharing the same OS layer, all containers share the one operating system.

What makes a company an ISP is their presence on the Internet.
**The telephone exchange **
The Glasgow central telephone exchange

Telehouse exchange in London, where many ISPs connect to the wider Internet.

Don’t make architectural decisions that are optimal for physical, but are not optimal for a virtual environmental.

#3 Don’t skip new features If you keep up to date with VMware, be aware of and utilise new features that will add value.

Rapid growth necessitates change.
Technological & organisational change both required, tools don’t help if can’t use them effectively. Empower your engineers
**Adopted a squads / tribes model **(ala Spotify) - teams between 1-10 people, localised ownership of sections of functionality from design through to development & running it, faster decision making - “You build it, you run it” - drives engineers to do things properly.
In no specific order, these are the podcasts that I have found useful & interesting.
If you find yourself with time to listen for 30 to 60 minutes at a time, these are one of the great ways to gain situational awareness of the current market & future trends & opportunities.
