Virtual Private Cloud: isolated networks
Connect your servers within private networks isolated from the internet – for secure internal communication and a clean architecture.
- Completely isolated – private traffic remains private
- Free segmentation by environment and application
- Internal traffic included – quickly and directly via the internet
- GDPR-compliant from German data centres
Private communication for your cloud resources
Virtual Private Clouds allow you to separate internal communications from the public internet – the foundation of secure, multi-tiered architectures.
True isolation
Your VPC is a private network: servers communicate via internal IP addresses, which are inaccessible from the public internet and to other customers.
Clear segmentation
Separate production, staging and development, or isolate applications from one another – by using separate subnets for each environment.
Fast internal traffic – free of charge
Data transfer to and within VPCs is free of charge, and you can create as many VPCs as you like at no extra cost. Excess data transfers from VPCs cost just €0.005 per GB – significantly less than with other cloud providers.
Smaller attack surface
Databases and internal services no longer require a public IP address – only what really needs to be accessible remains so.
Multi-stage set-ups made easy
Typical setup: a load balancer and web server with a public connection, whilst the application and database layers are located exclusively within the VPC. Combined with cloud firewalls at the gateway and managed services for operations, this creates an architecture that combines security and scalability.
- Public only where necessary load balancer and web servers at the boundary
- Application and database exclusively inside the VPC
- Cloud Firewalls at the boundary – rules where the traffic enters
- Managed Services for operation architecture designed and looked after
How customers structure their networks
VPCs form part of your ccloud³ infrastructure – you only pay for the servers and resources you use.
- Public web server
- Database for internal use only
- Firewall at the gateway
- A separate VPC for each environment
- No cross-references
- Identical topologies
- VPN to the company network
- Internal services are accessible
- Personalised planning
How much does a Virtual Private Cloud cost at Centron?
With centron, there is no basic charge for a Virtual Private Cloud, and internal traffic within the VPC is not billed. The VPC isolates your servers within a private network: the web server remains publicly accessible, whilst the database behind it is accessible only internally – external attacks cannot reach them in the first place. For separate environments such as development, testing and production, you can set up a dedicated VPC for each with identical topology, without any cross-access between them. On request, the VPC can be connected to your company network via VPN, ensuring that internal services remain accessible.
| Characteristic | Value |
|---|---|
| Internal traffic | €0.00 / GB – free within the VPC |
| Network segmentation | Public and private subnets can be freely defined |
| Typical structure | Web server is public; database is accessible internally only |
| Connection to the company network | via VPN, individually scheduled |
