Whether for Disaster Recovery/Business Continuity purposes, or for ensuring optimal performance of mission critical applications, many companies have expressed interest in a managed high availability (e-HA) service that can seamlessly re-direct traffic to servers in operational data centers as necessary, plus provide customized performance-based load-balancing to ensure that the user experience is optimized.
AIS e-HA 2.0 provides state-of-the-art Disaster Recovery / Business Continuity through the use of enterprise-grade infrastructure and by leveraging the company’s highly redundant, geographically diverse data centers.
AIS e-HA 2.0 consists of two basic services and several bundled services that utilize F5 global and local traffic managers for monitoring the state of the target servers and the location of the requesting client, and then directing traffic accordingly.
Highlights of AIS e-HA 2.0:
- State-of-the-art local and global load balancing technology
- High-performance private network between data centers
- Expert engineering and support staff
- Extensive transit and peering network
- Fully monitored and managed service
AIS e-HA 2.0 consists of Local HA, Global HA, Local HA Bundle, Global HA Bundle and Total HA.
- AIS Local HA provides server-level load balancing and failure detection, custom service monitoring through the use of enterprise-class hardware from F5 Networks.
- AIS Global HA is operated from two geographically diverse data centers (AIS San Diego and AIS Phoenix). It provides DNS-level load balancing and failure detection through the use of enterprise-class hardware from F5 Networks.
- AIS Total HA combines AIS Local HA and AIS Global HA services into an integrated hardware solution designed for quick recovery and business continuity. It leverages the AIS private optical network that runs between the San Diego and Phoenix data centers -- providing high-performance, secure connectivity that enables real-time data replication and service delivery from multiple points on the Internet).

AIS, being well versed in what enterprises need to succeed, has assembled a comprehensive managed service solution, the
Enterprise High Availability (e-HA) service, that leverages key components from the
AIS Toolbox:
Enterprise High Availability (e-HA) Managed Service
- State-of-the-art local and global load balancing technology
- High-performance private network between data centers
- Expert engineering and support staff
- Extensive transit and peering network
- Fully monitored and managed service
To start, the AIS Engineering and Professional Services staff (“ProServices”) are experts in networking and high-availability infrastructure. Plus, they are experienced in load-balancing technology at the local and global scale.
The AIS private optical network provides high-performance, secure connectivity between all of our datacenters, allowing real-time data replication and service delivery from multiple points on the Internet. The network consists of OC-192 (10Gbps) optical links from multiple providers and in some cases incorporates dark fiber links to meet the client’s operational requirements.
Enterprise redundancy extends to our transit and private peering connections: AIS has managed over 40Gbps of transit and peering across four data centers.
Monitoring is provided by the AIS Operation and Control Center (OCC), which is manned 24x7x365, ensuring that a team of highly skilled professionals is always available to provide personalized support and to quickly troubleshoot/fix any technical issues that are encountered. The AIS commitment to using a people based approach is a key differentiator.
These features add up to a turnkey high-availability service that saves money and increases uptime.
How Does It Work?
In the most basic configuration, a website (e.g. www.domain.com) is assigned to a pair of high-availability load balancers. Each load balancer is located in a separate, fully autonomous data center. The High Availabilty (e-HA) devices are configured to direct traffic to the appropriate web server(s) by using DNS and handing out IP addresses when users access the website. The “appropriate” web server can be determined by a number of configurable parameters, such as server availability, request origination, and fastest performance.
For DR/BC applications, the HA devices use constant monitoring to determine whether the primary site (or web server) is available. Traffic is directed to the primary site unless a failure is detected, then traffic is quickly directed to the secondary site (or server). For users that had been previously directed to the primary (failed) site, subsequent requests are redirected to the secondary site.
All of this traffic direction occurs outside of the client’s colocation footprint and failover may be configured to occur without human intervention. There is no client-side hardware or software required. Support is provided 24x7x365 by Operations Control Centers located in three autonomous data centers.
Need Help Getting Started?
Custom HA configurations are tailored to client DR/BC objectives by the AIS ProServices engineering team. AIS ProServices offers full-service consulting for Disaster Recovery / Business Continuity (DR/BC) planning, drawing on a number of unique AIS advantages, such as the AIS DR/BC Toolbox to produce fully managed enterprise-ready solutions.
To ensure the solutions conform to best-practices, the AIS ProServices team follows a disciplined methodology based on a four-part life cycle model: Assess, Design, Implement, and Operate. Each stage in the model represents an important aspect of the overall solution.
