4 Layers of AWS Architecture a Quick Answer

I have collected real interview questions on AWS key architecture components. Those are S3, EC2, SQS, and SimpleDB. AWS is one of the most popular skills in the area of Cloud computing. Many companies are recruiting software developers to work on cloud computing.

AWS Key Architecture Components AWS is the top cloud platform. The knowledge of this helpful to learn other cloud platforms. Below are the questions asked in interviews recently.
What are the components involved in AWS?Amazon S3.With this, one can retrieve the key information which is occupied in creating cloud structural design, and the amount of produced information also can be stored in this component that is the consequence of the key specified.Amazon EC2. Helpful to run a large distributed system on the Hadoop cluster. Automatic parallelization and job scheduling can be achieved by this component.Amazon SQS. This component acts as a mediator between different controllers. Also worn for cushioning requirements those are obt…

How Hadoop is best suitable for large legacy data

I have selected a good interview on legacy data. You all know that a lot of data is available on legacy systems. Hadoop is the mechanism you can use to process the data to get great business insights.

1). How should we be thinking about migrating data from legacy systems?
  • Treat legacy data as you would any other complex data type. HDFS acts as an active archive, enabling you to cost-effectively store data in any form for as long as you like and access it when you wish to explore the data. And with the latest generation of data wrangling and ETL tools, you can transform, enrich, and blend that legacy data with other, newer data types to gain a unique perspective on what’s happening across your business.
2). What are your thoughts on getting combined insights from the existing data warehouse and Hadoop?
  • Typically one of the starter use cases for moving relational data off a warehouse and into Hadoop is active archiving. This is the opportunity to take data that might have otherwise gone to archive and keep it available for historical analysis. The clear benefit is being able to analyze data for the types of extended time periods that would not otherwise be cost feasible (or possible) in traditional data warehouses. An example would be looking at sales, not just in the current economic cycle, but going back 3 – 5 years or more across multiple economic cycles. 
  • You should look at Hadoop as a platform for data transformation and discovery, compute-intensive tasks that aren’t a fit for a warehouse. Then consider feeding some of the new data and insights back into the data warehouse to increase its value.
3). What’s the value of putting Hadoop in the Cloud?
  • The cloud presents a number of opportunities for Hadoop users. Time to benefit through quicker deployment and eliminating the need to maintain cluster infrastructure Good environment for running proofs-of-concept and experimenting with Hadoop Most Internet of Things data is cloud data. Running Hadoop in the cloud enables you to minimize the movement of that data The elasticity of the cloud enables you to rapidly scale your cluster to address new use cases or add more storage and compute.
