‘In-Memory’: What’s the big deal?

By diane harvey | May 27, 2014 | HANA , SAP

Firstly – what does In-Memory actually mean?

Let’s dive into in-memory. Starting with RAM (Random Access Memory), which is what enables you to store data on your computer system, then change it, delete it etc.

The cost of RAM has fallen in recent years and the way that it performs has subsequently improved, which means that the amount of data that can be stored in its memory is far greater than before.

Think about disk-based data warehouses, or even how many disks you own that store large amounts of data.  They’re no longer needed, as the data is all now available, quickly and simply from your system’s memory.

So – if this isn’t new news, why does In-Memory suddenly sound like it’s the next big must-have?

It’s the way that In-Memory computing can now be used.  Take SAP’s In-Memory platform for example.  Called HANA, which is short for high performance analytic appliance, it’s leading the innovation in In-Memory computing by performing 10,000 times faster than standard memory disks.  It does this by using sophisticated data compression, which enables searching, processing, reporting and analysing of data in literally seconds instead of hours, or even days.

According to analyst company Gartner, 10% of large and medium sized companies have already adopted In-Memory computing and predicts that by 2015, that figure will have more than tripled to 35%.

The main benefits are obvious.

Save time, save money.  But also think about manpower: consultants and support desks will no longer be needed for creation of ad-hoc reports, it can all be done quickly and easily by your own users.  Detection of patterns and the ability to answer complex questions is also lightning fast and accurate, through HANA’s In-Memory analytics.
