A global IT Firm is working on a project to process Genomics data for a scientific organization. Researchers are looking for a quick analysis of large amounts of data they need to retrieve from any part of the world seamlessly. IT Firm has AWS Direct Connect link from on-premise Datacenter to AWS VPC. As an AWS consultant, they are looking for your guidance to provide a long-term cost-effective solution that can handle any amount of data reliably.
Which of the following solutions can be deployed to meet IT firm requirements?

Answer options:

A.Use Amazon EMR with Apache Spark & data stored in Amazon S3 bucket.
B.Use Apache Spark deployed at on-premise servers with data stored in Amazon S3 bucket.
C.Use Amazon EMR with Apache Spark & data stored in Amazon EC2 instance store.
D.Use Apache Spark deployed at on-premise servers with data stored in Amazon EC2 instance store.

Correct Answer: A
Amazon EMR is a big data platform used for processing large amounts of data. For analyzing large amounts of data, Amazon EMR can be used to provide reliable cost-effective solutions. It supports open-source tools like Apache Spark, Apache Hive, Apache HBase, Apache Flink, Apache Hudi, and Presto. Data can be stored in an Amazon S3 bucket to have scalable storage options & can be accessed globally. With EMR Cluster, compute & storage are decoupled. For storage, Amazon S3 can be used. For compute, clusters can be launched as per processing required & stopped when there is no requirement, saving additional cost. When Apache Spark is deployed on-premise, customers must manage physical infrastructure & large processing requirements. There is an additional cost of building new infrastructure.
Option B & D are incorrect as deploying Apache Spark at on-premise servers would be a non-scalable solution & will incur additional cost for managing server farms.
Option C is incorrect as storing analytical data in Amazon EC2 instance store would be ideal only for temporary solution & not for long term reliable storage.
