A solutions architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon.The application is designed to ingest millions of small records per minute from devices all around the world.Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency.The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.The solutions architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB.Which storage strategy is the MOST cost-effective and meets the design requirements?Read More →

A retail company wants to improve its application architecture.The company’s applications register new orders, handle returns of merchandise, and provide analytics.The applications store retail data in a MySQL database and an Oracle OLAP analytics database.All the applications and databases are hosted on Amazon EC2 instances.Each application consists of several components that handle different parts of the order process.These components use incoming data from different sources.A separate ETL job runs every week and copies data from each application to the analytics database.A solutions architect must redesign the architecture into an event-driven solution that uses serverless services.The solution must provide updated analytics in near real time.Which solution will meet these requirements?Read More →
