TIEFGANG

FOR THE CURIOUS · NO IT KNOWLEDGE NEEDED

How does a cardboard box become a workstation?

When someone joins a company, the first thing waiting is a laptop in a box. Seven things need to happen before Jana can work with it. In a well-planned IT environment, many happen almost on their own. Tiefgang shows you what that looks like — and even lets you pull a cable.

Jana’s laptop travels through four levels: application, network, server and hardware.

The laptop’s journey in seven steps

Each step has a time, a technical term for insiders and an everyday comparison for everyone else.

01

Unboxing

Inventory

Like a name badge: the laptop gets an inventory number and an owner before it is allowed to do anything.

WHAT DOES IT HELP?

You always know which device is where.

02

The network

VLAN · Firewall · Switch

Like separate roads with a gatekeeper: the laptop stays in its own lane, and only permitted routes are open.

WHAT DOES IT HELP?

Strangers cannot reach sensitive services.

03

Address

DHCP

Like a house number: without one, the post cannot find the laptop. Four short messages, then it has one.

WHAT DOES IT HELP?

Nobody has to assign addresses by hand.

04

Operating system

PXE · Deployment

Like a factory-built house: the system arrives over the network. Nobody runs from device to device with a USB stick.

WHAT DOES IT HELP?

Every laptop starts with the same approved setup.

05

Sign-in

Active Directory

Like an employee pass: one identity opens exactly the doors that match Jana’s tasks.

WHAT DOES IT HELP?

Permissions are managed in one place, not a hundred.

06

Software

UEM · baramundi

Like a delivery service with a receipt: programs arrive automatically, and IT sees whether they really made it.

WHAT DOES IT HELP?

Not just an installer that was “somehow” started.

07

Backup

Backup · Restore

Like a safe deposit box off-site: if something is lost, there is a copy. A test checks that it works.

WHAT DOES IT HELP?

Files can be recovered after data loss.

BONUS · TRY IT YOURSELF

Two paths

Redundancy · uplink A/B

Like a diversion around roadworks: if a cable fails, traffic takes the second route. Try it: pull a cable.

DISTINCTION

Redundancy keeps things running; a backup brings lost data back. You need both.

Pull the cable ↗

Three reading depths: the same chapter, your choice

The “Reading depth” control switches between levels in the experience. Simple is the default; technical detail stays one click away. Here is the DHCP example.

Simple

for everyone

The laptop asks the network for an address and receives one. Like a house number for the post.

Explained

for curious readers

The DHCP server supplies an address, gateway and DNS in four steps: Discover, Offer, Request, Acknowledge. The laptop may use the address only once the server confirms it.

A glossary in one sentence

Client
The device someone works on. Here: Jana’s laptop.
Switch
A cable distributor: it connects all devices in the building.
Access point
A transmitter for the Wi-Fi.
Firewall
A gatekeeper between networks: it lets only permitted traffic through.
VLAN
Separate “lanes” on the same cabling.
DHCP
Hands out network addresses automatically.
DNS
The network’s phone book: it turns names into addresses.
Gateway
The exit from your own network to other networks.
PXE
Starting over the network instead of from a USB stick.
Active Directory
A central directory for accounts, groups and permissions.
Hypervisor · VM
The hypervisor splits one server into several virtual servers (VMs).
UEM (baramundi)
Management that brings programs and settings to devices. baramundi is one such product.
Redundancy
Important parts exist twice so operation continues when one fails.
Backup · restore
A backup is a copy of the data in another place. A restore brings it back.

Why automate all this?

Fewer errors

Every laptop gets the same approved steps rather than a different setup each time.

Traceability

IT can see what was installed and whether it worked.

More time for people

Less manual installation leaves time for problems that really need a thoughtful person.

Model or practice?

IN THE MODEL (TIEFGANG)

Jana, the laptop and the 35 minutes are an illustrative model. Time is compressed, not measured. The chapters show a logical journey, not a mandatory boot order or a complete network topology.

IN PRACTICE (FINAL PROJECT)

Enzkreis District Administration: a baramundi pilot environment as a basis for a possible future replacement of Matrix42 Empirum. 40 hours, four fully successful reference clients out of five planned. A pilot, not a complete production migration.
