Scaling Smart: Active Directory Configurations for Growing Companies


  • A single bare-metal domain controller (DC),
  • One bare-metal and one virtual machine (VM) based DC,
  • Both as VM-based DCs,
  • Or both as bare-metal without any VMs?
  • Additionally,

could you provide insights on the feasibility and potential costs of integrating a cloud-based DC for a business with 10 users that has the potential to scale? Thank you.


A Single Bare-Metal Domain Controller (DC)

A single bare-metal DC can be a cost-effective solution for a small business. It eliminates the complexity of managing virtual machines (VMs) and can be sufficient for a company with a small number of users. However, it lacks redundancy and could lead to significant downtime in case of hardware failure.

One Bare-Metal and One VM-Based DC

This hybrid approach offers a balance between reliability and cost. The bare-metal DC ensures stable performance, while the VM-based DC provides flexibility and easier backup and recovery options. It’s a prudent choice for businesses that anticipate moderate growth.

Both as VM-Based DCs

Opting for two VM-based DCs can offer high availability and disaster recovery benefits. Virtualization allows for quick replication and migration of the virtualized DCs, which is invaluable for maintaining uptime. However, this setup requires a robust virtualization environment, which might increase initial costs.

Both as Bare-Metal Without Any VMs

Choosing two bare-metal DCs without VMs is the most straightforward approach but also the least flexible. It can be more expensive due to the need for two sets of hardware, and it doesn’t provide the same level of disaster recovery options as a virtualized environment.

Cloud-Based DC Integration

For a business with 10 users and potential growth, a cloud-based DC could be a strategic move. Cloud services like Azure Active Directory offer scalability and reduced maintenance. While the initial costs may be higher compared to on-premises solutions, the pay-as-you-go model can be economical as the company expands. The exact costs would depend on the specific cloud provider and the services chosen.

In conclusion, the choice between these configurations depends on the business’s current needs, growth expectations, and budget. A combination of one bare-metal and one VM-based DC often strikes a good balance for small businesses, providing both stability and flexibility. As for cloud-based solutions, they offer scalability and ease of management, which can be beneficial for a growing company. It’s advisable to consult with an IT professional to tailor the setup to the specific needs of the business.
