Big Data Architecture Stack Layers

Logical layers of a big data solution logical layers offer a way to organize your components.

Big data architecture stack layers.

What makes big data big is that it relies on picking up lots of data from lots of sources. Therefore open application programming interfaces apis will be core to any big data architecture. The data layer at the bottom of the stack are technologies that store masses of raw data which comes from traditional sources like oltp databases and newer less structured sources like log files sensors web analytics document and media archives. Increasingly storage happens in the cloud or on virtualized local resources.

Some unique challenges arise when big data becomes part of the strategy. Security layer this will span all three layers and ensures protection of key corporate data as well as to monitor manage and orchestrate quick scaling on an ongoing basis. They do not imply that the functions that support each layer are run on separate machines or separate processes. Big data layers as you see in the preceding diagram big data architecture or unified architecture is comprised of several layers and provides a way to organize various components representing.

Multiple analytics tools operate in the big data environment. In addition keep in mind that interfaces exist at every level and between every layer of the stack. The analytics layer interacts with stored data to extract business intelligence. In this layer analysts process large.

By judith hurwitz alan nugent fern halper marcia kaufman security and privacy requirements layer 1 of the big data stack are similar to the requirements for conventional data environments. New big data solutions will have to cohabitate with any existing data discovery tools along with the newer analytics applications to the full value from data. The big data architecture might store structured data in a rdbms and unstructured data in a specialized file system like hadoop distributed file system hdfs or a nosql database. The layers are merely logical.

The security requirements have to be closely aligned to specific business needs. The goal of most big data solutions is to provide insights into the data through analysis and reporting. The processing layer is the arguably the most important layer in the end to end big data technology stack as the actual number crunching happens in this layer.
