Networking

Networking

Networking services provide high-speed, high availability and secured network environment for cloud-native apps and services

Key features

Resource isolation

Resource isolation

Deploy Virtual Private Cloud (VPC) to isolate interrelated cloud resources from the rest of the cloud environment at the network level and control them. Documentation
Network segmentation

Network segmentation

Divide VPC into multiple segments using subnets, which can be created in different availability zones to make the deployed infrastructure more reliable and available. Documentation
Site-to-Site IPSec VPN

Site-to-Site IPSec VPN

Create secure connections between the cloud and remote infrastructure using advanced authentication, encryption and data integrity protocols and algorithms and improve availability with high-availability dual-tunnel VPN connections. Documentation
Flexible management

Flexible management

Manage network resources via the cloud web interface and AWS-compatible API and CLI. The resources of the same type will be easier to group if tagged.
Flexible IP addressing

Flexible IP addressing

Create virtual networks with up to 65,536 addresses and allocate arbitrary address space to them. To provide the access from the outside, you can rent Elastic IP addresses or register the existing provider-independent blocks of IPv4 addresses. Documentation
Multi-tier protection

Multi-tier protection

Secure your cloud resources using access control lists and security groups to filter inbound and outbound traffic against configurable rules for subnets and network interfaces. Documentation
External networks

External networks

Connect cloud infrastructure to the corporate network via a dedicated channel. To connect the external network, you can either install the equipment in a CROC data center, or lease a channel to your site from our partners. Documentation
Network map

Network map

Visualize the network architecture using the network map with the required degree of detail and display relationships between the components. Documentation

Use cases

Secure private cloud

Create virtual private clouds to implement your projects. Double filtering using access control lists and security groups helps control access to cloud resources both inside the VPC and from the outside.

Hybrid infrastructure

Cloud resources can be networked with the corporate infrastructure. The enterprise data center and CROC Cloud can be connected via a communication channel with 10+ Gbps bandwidth. Learn more

Cloud hub

Securely connect your remote sites through the cloud — just connect them to the same VPC via VPN. A VPN connection can also be established between private clouds, or a private cloud and a VPC. Learn more

Backup site

If the main site fails, the necessary resources can be promptly deployed in a virtual private cloud using automation tools. Data can be backed up from on-premise infrastructure to CROC Cloud server via dedicated channel or public network.

FAQ
What is a virtual private cloud all about?
Virtual Private Cloud (VPC) provides an isolated network environment to run CROC Cloud services. You can create cloud resources inside the virtual private cloud in all three availability zones, each based on a separate data center. The distribution of cloud resources across different availability zones minimizes the negative effect caused by the incidents in one of them.
How many subnets can be connected to an instance?
Instances can feature up to 16 network interfaces for connection to subnets, so you can grant a VM access to subnets, which must be isolated from each other, for example, for security reasons. This can be useful when deploying virtual network appliances (L3/L4/L7 firewalls, IPS, IDS, certified VPN appliances, etc.), separating data and control traffic, or providing different services on different interfaces.
Networks of what size can be created in the cloud?
VPC can be a network of 16 to 65,536 addresses (/28 to /16 in CIDR notation). It is the user who sets the network size when creating a VPC. Select the size, so that the number of subnets and IP addresses, which can be created in the VPC, would be sufficient for both your current needs and further project scaling and development.
How is traffic filtered?
CROC Cloud features double filtering, using security groups and access control lists (ACL). Security groups filter traffic at network interfaces of a particular VM, while access control lists act as a firewall between subnets. By default, security groups block all the traffic, while ACLs, on the contrary, permit it. Double filtering make it easier to separate traffic in a network infrastructure with a complicated topology. Learn more about security groups and ACL.
What VPN connection capabilities are supported?
Cloud-based VPN service (VPN as a Service, VPNaaS) enables you to rapidly connect CROC Cloud with the remote infrastructure via IPSec VPN in either tunnel, or transport mode. In addition, VPN connection can be established with other cloud platforms (e.g. AWS) or even between two different VPCs in CROC Cloud.

VPNaaS supports advanced security protocols and algorithms and allows you to choose which tunnel options to use when establishing a VPN connection. This contributes to a truly secure connection and makes VPNaaS more compatible with customer equipment. You can, for instance, seamlessly connect cloud infrastructure to your site using a MikroTik router and IPSec in a tunnel mode, as well as configure the connection between the cloud and Cisco ASA, even if its firmware version does not support IPSec VTI.

The high availability VPN connection mode implies the creation of two tunnels. In normal operation, both tunnels are active. If one of the tunnels fails, all traffic is automatically redirected through the second tunnel, so that cloud resources are still available. To increase availability, tunnels are terminated in different availability zones. Each tunnel can be configured independently. Learn more
