Choosing the right hosting for your 3CX Phone System is one of the most critical decisions for optimizing performance, scalability, and cost. At AltF9 Technology Solutions Pvt Ltd, we understand that navigating the cloud landscape can be complex. That’s why we’ve prepared this guide to help you select the ideal hosting environment.
3CX offers incredible flexibility, allowing you to choose between a fully managed solution or hosting it yourself in a private cloud.
Understanding Your 3CX Cloud Hosting Options
3CX is a software-based PBX, and its deployment flexibility is a key advantage. You have two primary cloud-based paths:
1. Hosted by 3CX (Managed Service)
- What it is: A simple, fully managed solution where 3CX handles the infrastructure (OS, security, updates, and monitoring) on their own Tier 1 cloud provider accounts.
- Pros: Maximum simplicity, minimal IT overhead, and fast deployment.
- Cons: Higher annual license cost compared to the self-hosted license, and less granular control.
- Ideal For: Businesses prioritizing simplicity, hands-off maintenance, and a predictable, all-in-one solution.
2. Self-Hosted (Private Cloud)
- What it is: You deploy and manage your 3CX instance on your own account with a major cloud provider (AWS, Google Cloud, Azure, DigitalOcean, etc.).
- Pros: Lower annual license cost, complete control over the server environment, and full access for custom integration.
- Cons: Requires in-house IT expertise or a specialized partner to manage the Operating System, security patches, and backups.
- Ideal For: Businesses with existing IT staff, strict compliance requirements, or a desire for maximum control and customization.
The Self-Hosted Advantage: Choosing Your Cloud Provider
If you opt for the greater control and potential cost savings of Self-Hosted, selecting the right cloud provider for your Virtual Machine (VM) is critical for call quality and management.
| Cloud Provider | Key Differentiators | Ideal for Self-Hosting if… |
| Amazon Web Services (AWS) Lightsail | Simple & Affordable: AWS’s simplified VPS offering. Pricing is fixed and predictable. | You prioritize predictable, bundled monthly costs and high performance without the complexity of full AWS EC2. |
| Google Cloud Platform (GCP) | Robust Global Network: Known for low network latency, which is crucial for high-quality VoIP. | Network performance is your top priority or your team is familiar with the Google environment. |
| Microsoft Azure | Ecosystem Integration: Seamlessly integrates with the Microsoft stack (e.g., Azure AD, Microsoft 365, Teams Direct Routing). | Your IT infrastructure is Microsoft-centric and you need deep integration capabilities. |
| DigitalOcean | Developer Friendly: Highly intuitive interface and straightforward, transparent pricing. | You prefer simplicity, speed, and a user-friendly management portal over the vast complexity of hyperscalers. |
💡 Tip: For VoIP, the most critical factor is low latency. Choose a cloud region geographically closest to your primary user base to minimize delays and ensure clear call quality.
🔑 Critical Factors for a Successful 3CX Cloud Deployment
- Concurrent Calls (SC): 3CX licensing is based on Simultaneous Calls, not the total number of users. Always size your license and your cloud server VM based on your peak call volume.
- Backups: Whether hosted or self-hosted, regularly test and verify your backups. For self-hosted, you are entirely responsible for the server snapshots and disaster recovery plan.
- Security: In a self-hosted environment, you must actively secure the underlying Linux or Windows server OS and maintain security updates.
