But Why?

WHY? Oh I will tell you why.

What do I do?

Troubleshoot technical issues
Maintain physical infrastructure
Update software
Setup Zoom calls
Fix printers
Develop websites
Repair or replace obsolete hardware
And as always... other duties as assigned

But I can do those things!

Can it scale?
Is it secure?
What happens when someone leaves?
What happens when something breaks?
How do you backup data?
Does it get your full attention?

How much will this cost?

$$$

It's complicated

Technology is ever changing
The 'as a service' model adds up
Business class internet is a rip off
Remote work means more reliance on the cloud.
There isn't a one size fits all solution.

There are ongoing costs as well as one time purchases with any aspect of business. Technology is no different. The pandemic has changed our reliance on certain aspects of tech and as such the costs associated with them has changed.

While you can spend less in some areas, there are areas where spending the money is worth it.

There will always be something to upgrade.
SaaS products are generally more convenient than standing up your own infrastructure. However, this locks you into a platform and it's not always easy to leave. O365/ Adobe CC
Business and enterprise internet comes with SLA requirements, but you pay the price for it. Working internet on a Sunday morning example.
There is no cloud. Its just someone elses computer.

No money no problem

You don't always need the cutting edge
Enterprises love tax write-offs
Non-profits can get special pricing
Learn to love Open Source
Outsourcing is not always cheaper

However...

It benefits you to buy the best you can afford
One mans trash is not always another's treasure
You need to be ok upgrading

It benefits you to buy the best you can afford
One mans trash is not always anther's treasure
You need to be ok upgrading
Sometimes a paid solution is the best
Paying an expert can save you a lot of headache

Nuts and Bolts

Lets talk hardware

Office Computers

Go for business class
Used enterprise hardware is a great bang for the buck.

CPU: At least 4 true cores
Memory/RAM: 16GB
SSD: At least 256GB
HDD: 1TB (Only as file storage)
Dedicated Graphics Card: It depends

Laptops vs Desktops

Networking - 1 The basics

Enterprise vs home networking
Basic terminology

Router
Firewall
Switch
Access Point

How they all fit together

Networking - 2 Wifi

Common mistakes

Too few access points
Transmit power too high
Channel congestion
2.4GHz interference

Brands to know

Ubiquiti
TP-Link
Aruba Networks
Cisco Meraki

Wifi is tricky to get right and its only noticed when it isn't working. With a few simple tweaks wifi performance can be greatly improved.

Generally, you don't want an access point to have to reach more than one room over. ~30ft
This goes hand in hand with too few access points. If the transmit power is too high the signal from an access point can overpower one that may be closer to the device trying to connect.
In especially dense urban areas there are lots of wifi networks. They all use the same few channels to communicate so selecting one that is not as highly used will allow for easier communication.
Lots of devices can give off 2.4GHz signals. Or in short, don't put your access point on top of the break room microwave.

Ubiquiti: Sleek, does the job well, user friendly, cost premium, no recurring charges
TP-Link Omada: Does everything Ubiquiti can just cheaper. Not as user friendly
The Aruba IAP line is good for 2 or 3 ap deployments where a central controller would be overkill. Going beyond the IAP line is pricy.
Cloud managed. Industry leader. The price will reflect that.

Networking - 3 Switches

Managed vs Un-managed
Speeds

100 megabit
1 gigabit
10 gigabit

Power over ethernet
Fiber optics vs copper

Networking - 4 Firewalls and Routers

The gateway to the internet
Firewalls often act as the router in a network
Old desktops make great firewalls
Any firewall you build or purchase will outperform the ISP provided one
