Managed Load Balancing

Modern hosting solutions generally do not consist of only one server. However, to ensure that all incoming traffic is balanced efficiently to all servers, or in the case of an issue, the traffic must be rerouted. Zonesa provides the Managed Load Balancing solution to meet these requirements.

Solution Description

The Managed Load Balancing solution is designed to route the traffic through a redundant infrastructure of load balancers to achieve an optimal load sharing between all servers. The complete management, administration and maintenance are conducted by Zonesa. This service includes the hardware, connectivity, and any additional ordered services. In addition, the customers are supported by the Zonesa Support Team.

Managed Load Balancing contains the following services:

• Consulting (technical specification of the individual service)
• First setup for load balancing (VLAN, VIPs etc.)
• Customization of technical parameters after consultation
• Documentation of the service and configuration
• Setup of server hardware and services
• Service and monitoring of the entire infrastructure

Technical Description

To configure a load balancing service, a virtual IP (VIP) needs to be set up on the load balancers, which is publicly accessible. All traffic is addressed to this VIP and gets load balanced to the real servers. There are different load balancing methods available; such as round-robin, or least-connection. Furthermore, safe balancing sessions, e.g. using cookies or read the http header, are possible.

Configuration

The complete configuration and administration is handled by Zonesa. A meeting will be arranged between the customer and the Zonesa Technical Consultant team. In order to change the initial setup, it will be necessary to send an alteration request to the Technical Consultants. After approval the change will be done.

Service Level

A service level agreement is offered for Zonesa Managed Load Balancing. It contains service availabilities, maximum recovery times, and maximum response times. The Service Level Agreement is provided as a separate document.
