AWS Lake Formation

A secure data lake can be quickly built up using the service AWS Lake Formation. All of your data, both in its unprocessed state and when it has been prepared for analysis, is kept in a centralised, curated, and secure repository called a data lake. You can eliminate data silos and combine various analytics to generate insights and inform smarter business decisions by using a data lake. Today, there are many tedious, challenging, and time-consuming steps involved in setting up and administering data lakes. In this work, data is loaded from various sources, data flows are monitored, partitions are set up, encryption is enabled, keys are managed, transformation operations are defined and monitored, data is organized into a columnar format, redundant data is de-duplicated, and linked records are matched. Following the loading of data into the data lake, you must allow fine-grained access to datasets and track access over time across a variety of analytics and machine learning (ML) tools and services. Determining the data sources and the access and security policies you wish to use is all that is necessary to create a data lake using Lake Formation. After that, Lake Formation assists you in gathering and cataloguing data from databases and object storage, moving it into your new Amazon Simple Storage Service (S3) data lake, cleaning and categorizing it using machine learning (ML) algorithms, and securing access to your sensitive data using granular controls at the column, row, and cell levels. A centralized data catalogue that lists available datasets and suggests uses for them is accessible to your users. Then, they use these datasets with the analytics and machine learning services of their choice, such as Amazon Redshift, Amazon Athena, Amazon EMR for Apache Spark, and Amazon QuickSight. Lake Formation enhances the capabilities already in place. Then, they use these datasets with the analytics and machine learning services of their choice, such as Amazon Redshift, Amazon Athena, Amazon EMR for Apache Spark, and Amazon QuickSight. Lake Formation expands on the features offered by AWS Glue. Amazon S3 forms the storage layer for Lake Formation. If you already use S3, you typically begin by registering existing S3 buckets that contain your data. Lake Formation creates new buckets for the data lake and import data into them. AWS always stores this data in your account, and only you have direct access to it. You can use AWS Glue, which is integrated with AWS Lake Formation, to build a data catalogue that lists the accessible datasets and the suitable business applications for each. With straightforward "give and revoke permissions to data" sets at fine-grained levels, Lake Formation enables you to design policies and regulate data access. Using federation, you may grant permissions to IAM users, roles, groups, and Active Directory users. Instead of using buckets and objects, you provide rights on catalogue objects (such tables and columns).
