What is a load balancer?
Load balancer is a service that enables resource load balancing, i.e. distributing tasks among multiple processors, servers, disks, network connections, etc.
One of the most common uses of load balancing is to ensure that a single service runs on multiple servers, called a server farm or server cluster.
Load balancers are also widely used in popular websites.
Advantages of load balancer in Atman Cloud
High service availability as standard
All load balancers for Atman Cloud customers are created in HA (High Availability) architecture by default.
Several configurations to choose from
Available load balancer configurations (see the documentation for details):
- HTTP (traffic without data encryption)
- HTTPS (direct forwarding of encrypted traffic to backends)
- HTTPS_TERMINATED (unpacking SSL traffic in load balancers and forwarding already decrypted traffic to backends)
- TCP
Wide selection of management tools
You can run and configure the service using: web panel, OpenStack CLI, API or other tools, e.g. Terraform, Ansible, etc.
Flexibility, performance, scalability
We offer three load balancer preformance levels, up to a maximum throughput of 1000 Mbps. You can activate a new service or deactivate a running one at any time.
Security guarantee
We provide logical and hardware level redundancy, as well as 24/7 technical support. You benefit from a high SLA – 99.97% service availability.
Billing in the PAYG model
We use “pay as you go” billing, so you pay according to the service usage, for each hour of work started. You do not bear the costs of data transfer.
Main benefit: increased availability of your applications
Balancing traffic to your websites or web applications increases their availability, and speeds up the handling of user requests.
By ensuring that your services are accessible and run smoothly, you protect yourself from the consequences of their temporary unavailability, including potential financial losses.
Load balancer - how to start?
Configure load balancing in your environment in Atman Cloud
Set the maximum number (limit) of load balancers you may need at the same time.
Sign a contract (or an annex) with a defined overall limit of load balancers that you will be able to invoke concurrently (regardless of their chosen performance).
Start the load balancer service in the Horizon panel or with other service management tool, selecting:
- One of the three load balancer capacities available
- The type of configuration
- The traffic distribution algorithm

Load balancer capcity
| Type | Maximum throughput |
| Standard | up to 200 Mbps |
| Fast | up to 500 Mbps |
| Ultra | up to 1000 Mbps |
Available algorithms of load balancing
| Algorithm | Operation mode |
| Round-Robin | Distributes requests to the servers in the list in rotation |
| Least connections | The query is directed to the server that has the least active connections |
| Source IP | Queries from a given source IP go to the backend that handled the first one |
