Hi,

We have a scenario wherein backend system is called for data, the volumes are almost 1.5-1.6 million per day. At times when the backend system goes down or has problem in responding with the timeout interval , serious business impact is caused and leads to SLA breach.

As the volumes very huge and are dynamic,we would not be able to use global cache in the flow. Is there any other way to achieve this within IIB or anyother external component to be included.

Why not? That's a large number not a huge number, you don't mention the size of the data you're trying to store and the point of the cache is to hold dynamic data.

The simplest, obvious change would be to switch from the inbuilt global cache to the full extreme scale product. You could also load your data into DB2/Oracle/etc. and let the database platform caching handle it.

In your situation, I'd be more worried about how I kept the cache (wherever I ended up keeping it) in sync with this backend system.

I'd also be thinking about what I could do to increase stability and throughput on the backend system.

When the backend is not available, you could use MQ queueing or a staging DB to temporarily store requests / data, until they can be processed. You should be able to cater for a long outage (minutes - hours) or DR situation (a day or more).
