UniFi Cloud Key vs. Cloud hosted controller

If you're managing a UniFi network, you’ve likely considered whether to use a UniFi Cloud Key or a managed cloud controller like UniHosted.

Both let you manage UniFi devices remotely, but they differ in how much they scale, how much you have to maintain, and how much control you actually get.

This guide breaks down the key differences to help you choose the right option for your network.

UniFi Cloud Key

The UniFi Cloud Key is a hardware device by Ubiquiti, designed to run the UniFi Controller software. It connects to your network and offers a local solution for network management with cloud-based remote access.

Pros

• Local Control: Offers a dedicated physical device for managing your network.
• No Subscription Fees: One-time purchase with no ongoing fees.
• Easy Integration: integrates with existing UniFi devices.
• Direct Access: Provides direct access to the controller without third-party involvement.

Cons

• Limited Scalability: Hardware resources are fixed, limiting scalability.
• Physical Vulnerability: Susceptible to physical damage, power outages, and other on-site issues.
• Maintenance Responsibilities: Requires self-maintenance, including updates and backups.

Cloud controller

There are two ways of hosting. The do-it-yourself ways or managed cloud hosting. DIY Cloud Hosting involves setting up your own UniFi Controller on a cloud platform using services like AWS, Azure or a managed cloud controller by a third party like UniHosted.

DIY Cloud hosting: Full control over your cloud infrastructure.

Pros

• Full Customization: Complete control over the server setup and configuration.
• Scalability: Easily scale your server resources based on network demand.
• Remote Accessibility: Access your controller from anywhere with an internet connection.

Cons

• Technical Expertise Required: Requires knowledge of cloud platforms and server management.
• Ongoing Maintenance: You're responsible for all updates, security patches, and troubleshooting.
• Variable Costs: Costs can fluctuate based on resource usage and cloud service pricing.

Managed cloud controller

Cloud controller services offer a ready-to-go UniFi Controller hosted on cloud infrastructure. This approach involves using a service provider like UniHosted to do the managing for you.

Pros

• High Scalability: Easily scalable resources to meet growing network demands.
• Reduced Maintenance: The service provider handles updates, backups, and maintenance.
• Enhanced Reliability: Hosted in enterprise-grade data centers for increased uptime and reliability.
• Expert Support: Access to professional support and expertise.

Cons

• Ongoing Costs: Typically involves a monthly or annual subscription fee. However, UniHosted is free for home-users.
• Less Direct Control: The physical infrastructure is managed by the service provider. This is not necessarily a bad thing, but you are placing your trust in the hands of a service provider.
