HA Failover

In today’s data intensive business environment, every minute counts. Enterprises experiencing unplanned downtime can suffer an average $600,000 per hour in lost revenue.
Many companies solve business downtime via load balancing and high availability failover solutions. However, these existing HA solutions still do not guarantee application uptime upon a database server failure as the application Moreover, they are costly and complex to manage. For example, in MySQL deployments, there lacks a truly robust HA solution in the market.
Therefore, database availability is still an issue for customers with critical applications. Customer have resorted to are alternative solutions, none of which are optimal:
1. Up to 60% of companies have delayed security patches in order to reduce downtime, which exposed them to regulatory and compliance issues.
2. Some customers have implemented a manual failover scheme requiring an application restart. Upon a database outage, application downtime could last from 20 minutes to 3 hours, resulting in a loss of potential revenue for the Enterprise.

Heimdall Data’s enhanced HA solution avoids the above scenarios as it is provides the application resiliency necessary for maximum uptime. The key benefits of the Heimdall approach are the following:
1. Application aware automated failover: Most solutions today (e.g. F5 Networks, AWS Elastic Load balancer) are at the TCP/DNS layer, resulting in connection timeouts and reconnects. Heimdall Data provides always-on database connectivity.
2. No application or database code changes: Scaling out the database tier always requires rewriting the application; not anymore with Heimdall Data.
3. SQL-aware read/write split for complex routing to different geographies or data sources.
