how in memory computing changes everything
DESCRIPTION
SAP HANA utilizes cutting-edge in-memory computing technology to provide the enterprise with real-time data and avail a competitive edge. In 2013, I have created this presentation for the SAP HANA workshop conducted by me. Primarily, before jumping into HANA, audience needs a smooth transition...required to understand the proper necessity to attend the workshop.TRANSCRIPT

“Recent(last decade or so) changes in Business Requirement"
Financial institutions, cloud companies and other enterprises with large data centers are shifting toward keeping data ‘in memory.’
Even Gartner picked In-Memory Computing as one of the top ten strategic initiatives of 2013.
- Forbes
“The Web, a good part of the Web, is a few terabits. So it’s not unreasonable; we’d like to
have the whole Web in memory, in random access memory to speed it up.”
- relatively unknown entrepreneur at the Intel Developer Forum
(At that time, his company’s backbone consisted of 2400 computers)

2013 Experts estimate that the same company now operates more than 1 million
servers.
Facebook alone has 220 billion photos and 4.5 billion updates, likes, new
photos and other changes every day.

“Current and future needs of Customers/Business"
“[All] business
transactions [and]
queries, including
unrestricted
aggregations and time-
based sequences, can
be answered in just a
couple of seconds
(including the
surprisingly costly
presentation layer).” - Dr. Hasso Plattner
How In-Memory Computing can change Business?

“Business impact is HUGE due to In-Memory Computing"
What is In-Memory Computing?
10
"Computing should be within memory."
In-memory computing is a breakthrough technology that enables analysis of very large, non-
aggregated data at unprecedented speed in local memory (vs. disk-based
storage/database).
In Tech term
In Biz. term
In-memory computing helps to do complex analysis, plans and simulations based on real-time
data and made the results available immediately.
As more data is being generated, old-fashioned methods of data storage have been unable
to keep up. Moreover, businesses want data faster and in real time; customers can look at
information in any level of detail in real time.
…The answer? In-memory Computing.
In-Memory Computing Approach
11
"Computing should be within memory."
- Less Data Travel Time (reducing traffic time for data from disks)
- Use non-volatile memory / ‘memory tier’ (DRAM + flash)
- Column-oriented system (keeping data more into column-store)
- Data Compression
- In-Memory Database & In-Memory Application
- In-Memory Computing will trigger an entirely new programming model and
ultimately a new business model for S/W industries
Note : According to Microsoft, in-memory based system servers are in use just
15% of the time; i.e., 85% of your computing cycles go to waste because
the servers are waiting for something to do. That is a massive amount of
excess overhead in hardware, real estate, power consumption and productivity.
For a Data Center, energy consumption would drop by 80% since memory-
based systems consume less energy and require fewer air conditioners.
In-Memory Computing Approach
12
- Efficient communication between database layer
with the application layer
- Pushing more application semantics into data
management layer
Data compression achieves a reduction in disk space
- Different techniques, Light-Weight/Heavy-Weight
- Compression-aware query execution
- Data-Dependent Optimization
- Exploitation of current hardware developments
- Main Memory is the New Disk
- Non-Uniform Memory Access (NUMA)
- Multi-core processor parallelism
If transaction data is stored in a column-based table, then it
enables
- fast on-the-fly aggregations,
- ad-hoc reporting
- to take benefit from compression mechanisms (as column
data is of uniform type)
mapping to
memory
