AWS has additional services. Learning of these keeps you ahead in the learning curve. Here are those 15 questions.
1. What is Athena?
Athena lets you use SQL queries to find data stored in S3. If you have data stored in CSV, JSON, ORC, Avro, or Parquet format, simply upload it to S3 and use Athena to query it. Athena is serverless, so there’s no need to provision your own database or import your data.
2. What is AWS Backup?
AWS Backup lets you centrally configure backup policies and monitor backup activity for all your data stored on AWS. It supports EBS volumes, RDS databases, DynamoDB tables, EFS file systems, and Storage Gateway volumes.
3. What is AWSGlue?
Data can live in a variety of places on AWS. AWS Glue can discover, clean, and bring this data together in one place for analysis using the Apache Spark big data framework. It can extract and analyze data from S3 objects and relational databases such as MySQL, Oracle, and Microsoft SQL Server.
4. What is Batch?
Batch computing jobs are used for performing analysis on large data sets. Some examples of batch computing include financial risk modeling, graphics processing, simulations, and even analyzing genomes. Batch allows you to run thousands of batch computing jobs on AWS without building any infrastructure.
5. What is Cognitio?
Cognito lets you add user access control to your application. Cognito integrates with many identity providers including Amazon, Google, Microsoft Active Directory, and Facebook. You can also use Cognito to provide your users access to AWS resources without having to give them their own IAM credentials.
6. What is a database migration service?
Database Migration Service (DMS) makes it easy to migrate data from one database to another, whether it’s in the cloud or on-premises. DMS supports relational databases such as Aurora, Oracle, Microsoft SQL Server, MariaDB, and PostgreSQL, as well as nonrelational databases including MongoDB, DocumentDB, and DynamoDB. DMS also supports migrating data to S3, Elasticsearch, and Kinesis Data Streams.
7. What is EFS (Elastic file system)?
The Elastic File System (EFS) is a scalable file system for Linux instances. You can attach multiple instances to a single EFS volume so that they can all share the same files. EFS volumes are highly available, spanning multiple Availability Zones in a single VPC. EFS can scale up to petabytes in size without disruption and automatically scales down so you’re not charged for space you’re not using.
8. What is elastic MapReduce?
Elastic MapReduce (EMR) lets you analyze enormous amounts of data stored in the cloud. EMR supports the Apache Hadoop, Apache Spark, HBase, Presto, and Flink big data platforms.
9. What is the Inspector service in AWS?
Inspector analyzes your EC2 instances for security vulnerabilities and common-misconfiguration issues.
10. What is Kinesis?
Kinesis can ingest and process large amounts of data in real-time. It’s helpful to analyze large amounts of streaming data ( including access logs, video, audio, and telemetry).
11. What is Macie?
Macie automatically finds and classifies sensitive data stored in AWS. It uses machine learning to recognize sensitive data such as personally identifiable information or trade secrets and shows you how that data is being used in AWS.
12. What is Neptune?
Neptune is a graph database that you can use to store and query highly connected data sets. It’s useful for recommendation engines, social networks, fraud detection, and network security.
13. What is the use of SQS (simple queue service)?
Simple Queue Service (SQS) enables developers to create decoupled, distributed applications in the cloud. SQS is a message broker that different components of your application can use to send messages to each other. SQS scales automatically to accommodate any volume.
14. What is the real use of WorkDocs service?
WorkDocs is a secure content sharing and collaboration service. You can store any type of file in WorkDocs, and it provides previews and commenting functionality for documents such as Microsoft Office files, PDFs, and text files.
15. What is a WorkSpace service in AWS?
Workspaces let you provision Linux or Windows virtual desktops in the cloud. AWS manages the operating system, patching, and virtual desktop infrastructure. Users can connect to their virtual desktops from any PC and a variety of mobile devices.
