When talking about IT infrastructure nowadays, you will have to think about high availability as well. Especially when you work in a sector where data security and integrity is of very high importance such as banking and insurance. Law restrictions and competitive pressures force every business to think about how to keep their data safe. Therefore, high availability is not just a trendy word, but essential to you and your clients. Think about it, high availability not only keeps your things running, it also can help to prevent you from spending huge amounts of time and money on disaster recovery.
High availability means that even in case something happens, you and your data are still safe. To achieve exactly that you not only need a systems that notices a failure in an instant, but further offers a solution that reacts quickly and makes sure your date won't be lost. This is where the IBM MQ Appliance comes in.
The IBM MQ Appliance provides you with the opportunity to bring the messaging you know and the high availability you need together in one place. For that purpose, a pair of MQ appliances is deployed in a high availability group which also contains high availability (HA) queue managers. While the HA queue managers take care of your messaging traffic the appliances take care of the HA queue managers. The appliances do that by communicating with each other. If one appliance realizes the other one is not responding it takes over and thereby makes sure you don't have to worry about data loss.
As you can see, with the IBM MQ Appliance a new, high availability configuration is now possible with a pair of appliances that mirror messages and enable seamless takeover upon failure of an identified primary appliance. This solution includes failure detection for hardware and software problems. In addition, it supports manual failover for rolling upgrades and it is easier to set up than other high availability solutions due to the fact that among others shared file systems and discs are no longer needed. To ensure 100% fidelity, replication is synchronous over ethernet.
Doesn't that sound promising? What scenarios can you imagine to leverage from the IBM MQ appliance's high availability? You want to know more about high availability on the IBM MQ appliance? Read the IBM Redbooks publication:
