name 3 services in aws and explain them 

Amazon Web Services (AWS):

1. Amazon S3 (Simple Storage Service) - Object storage service.
2. Amazon EC2 (Elastic Compute Cloud) - Virtual servers in the cloud.
3. AWS Lambda - Serverless compute service.
4. Amazon RDS (Relational Database Service) - Managed relational databases.
5. Amazon DynamoDB - NoSQL database service.

Where is the data actually stored in aws (name 3 examples)

1. Amazon S3 (Simple Storage Service): Object storage service designed to store and retrieve any amount of data from anywhere on the web. It is highly scalable, durable, and commonly used for static website hosting, backup, and archival.

2. Amazon EBS (Elastic Block Store): Provides block-level storage volumes for use with Amazon EC2 instances. EBS volumes are used as durable and high-performance storage, suitable for databases, file systems, and applications that require low-latency access to data.

3. Amazon Glacier: A low-cost storage service for data archiving and long-term backup. It is designed for infrequently accessed data and offers a cost-effective solution for archival storage.

4. Amazon Elastic File System (EFS): Fully managed file storage service that can be easily shared across multiple EC2 instances. It is suitable for workloads that require scalable and shared file storage.

Name 5 services of GCP and explain them 

Google Cloud Platform (GCP):

1. Google Cloud Storage - Object storage service.
2. Google Compute Engine - Virtual machines on Google's infrastructure.
3. Cloud Functions - Serverless compute service.
4. Cloud SQL - Managed relational database service.
5. Bigtable - NoSQL database service for large analytical and operational workloads.
