Customers of
today have become finicky. With access to Internet at their fingertips at all
times (thanks to the smartphones), they are able to analyze products/services
faster than ever before. Social media platforms like Facebook and Twitter have
transformed into information portals for customers.
The wealth of knowledge
derived from these platforms sways the decision of millions and shapes the
fortunes of brands across the globe. For a business to prosper in the current
times, it has become crucial to unearth customer interest and launch
product/services accordingly. This is where Big Data analytics and stream
processing applications come into the picture.
The Importance of Real Time Data Stream Processing
Real time data stream processing can be put
to good use in a number of scenarios. It is particularly useful in situations
where data is in motion i.e. it is flowing either in or out of the system. User
actions on websites, data generated by sensors and financial trades in stock
exchange are prime examples of business situations where data is always
flowing. In such cases, Stream
Processing Applications can come in handy as they start working on the
data as soon as it is generated. Below are some of its important benefits:
Quick insight generation for devising business strategies
A Real
Time Data Stream Processing platform generates insights consistently.
So, whenever there is a situation developing, companies are able to understand
the trends fast and devise strategies accordingly to exploit the market
conditions.
Less money spent on storage of data
For
traditional data processing systems, large amount of storage space is required.
These systems first store the data on HDD or SSD and then process them in
batches. Hence, the money spent on storage systems is always high. Considering
the modern-day requirements posed by new tech like IoT that generates massive
amount of data, these systems are not cost-effective. On the contrary, an
in-memory based real
time data stream processing computes the data as soon as it arrives
thus reducing the storage space requirements. Therefore, it is a better fit for
newer technologies and emerging requirements.
Critical Attributes of a Real Time Data Stream Processing Platform
A real time data stream processing
platform can only be useful if it serves the present-day requirements of
business operations. Have a look at some of its essential attributes:
1. Fault tolerance – A data processing system is only useful if
it stays up for a long duration of time. Therefore, it needs to have high fault
tolerance to withstand minor faults and self-diagnostics capabilities to fix
the fault when it arises.
2. Horizontal scalability – The processing requirements may increase
at just about any time for a company. Therefore, the real time data stream processing platform should allow for the
addition of servers to meet the growing requirements.
3. Load balancers – When you have several platforms lined up in series, you require
load balancer feature to offload the work to a different server when one of the
server is under extreme load and likely to malfunction.
