The IDEAL IT Infrastructure Set-up for all Organizations

At times, people have come to me to seek help with their Infrastructure set-up for their businesses.
Although they appreciate my advise, many simply do not understand the value or the implications or the benefits in the long run of implementing a stable, ease of management and adequately redundant systems in the organization.

Any-how, what would entail an ideal small-business (or any business) IT infrastructure set-up?

Let's approach to what is needed in every organization:

1. Internet connectivity - fast and efficient
2. Reliability of connection - not problem free, but being able to know what is the problem when problem happens
3. Centralized storage for files - not just cloud-based, but a storage solution to maintain knowledge assets of the organization.
4. Backup-backup-backup - a way to have backup, and if possible-an archival backup solution where snapshots of files can be kept for yearly storage
5. Good working machines - of course users are at the center of all that is set-up. No users, then no need for infrastructure.
6. Secure working environment - protection from external malicious attack, and internal accidental actions
7. Audit-trail - having a form of logging to track and trace what happens in the organization
8. Disaster Recovery - what happens when the office gets burned-down? Do we have an operating else-where?
9. Ease of Connectivity for all users - WIFI is now-adays a defacto for all office networks. Mobile devices and BYOD implementations are core to every organizational effectiveness in allowing staff to be productive not just on company assets, but personal as well.
10. Centralized Authentication - People do not want to remember so-so many passwords... give me 1 to rule them all!
11. Presentable outputs - a sufficiently fast and eco friendly tool(s) to print, scan, copy, with the capability to trace... who printed what? 
12. Good Email System - these days, email seems to be linked to mortality. Users can DIE without email.. really?

Thinking about all of these should get an organization started on how IT can stabilize the business processes and then, implement line of business applications to further improve the business efficiency.

Having said that, the infrastructure is critical and having one that is 'open' and expandable is very critical to long-term benefits albeit a slightly costlier set-up.

I will post more in the days to come with the recommended solutions.
