Migration from Hadoop to cloud-native - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main reason organizations migrate from Hadoop to cloud-native platforms?

Organizations migrate to cloud-native platforms to gain better scalability, reduce infrastructure management, and leverage flexible, on-demand resources.

beginner

Name one cloud-native service that can replace Hadoop's HDFS for storage.

Amazon S3 is a popular cloud-native object storage service that can replace Hadoop's HDFS.

intermediate

What is a key benefit of using managed cloud services over self-managed Hadoop clusters?

Managed cloud services reduce the need for manual setup and maintenance, allowing teams to focus on data analysis rather than infrastructure.

intermediate

Explain the role of containerization in migrating Hadoop workloads to cloud-native environments.

Containerization packages applications and their dependencies, making it easier to deploy and scale Hadoop workloads in cloud-native environments like Kubernetes.

advanced

What is a common challenge when migrating Hadoop jobs to cloud-native platforms?

A common challenge is adapting existing Hadoop jobs and workflows to new cloud-native tools and architectures, which may require rewriting or reconfiguring code.

Which cloud service is commonly used as a replacement for Hadoop's HDFS?

A Microsoft Word

B Google Drive

C Amazon S3

D Dropbox

Amazon S3 is a scalable cloud object storage service often used instead of HDFS.

What is one advantage of cloud-native platforms over traditional Hadoop clusters?

A Requires more manual setup

B Needs physical hardware maintenance

C Has fixed resource limits

D Offers on-demand scalability

Cloud-native platforms offer on-demand scalability, unlike fixed traditional clusters.

Which technology helps package Hadoop workloads for easier deployment in cloud-native environments?

A Containers

B Virtual Machines

C FTP

D Email

Containers package applications and dependencies for consistent deployment.

What is a common challenge when migrating Hadoop jobs to cloud-native platforms?

A No need to change code

B Adapting workflows to new tools

C Unlimited storage

D Automatic migration

Migrating often requires adapting or rewriting workflows for new cloud tools.

Which of the following is NOT a benefit of migrating to cloud-native platforms?

A Higher physical hardware costs

B Better scalability

C Reduced infrastructure management

D Flexible resource usage

Cloud-native platforms reduce physical hardware costs, not increase them.

Describe the key benefits and challenges of migrating from Hadoop to cloud-native platforms.

Think about what changes when moving from on-premise Hadoop to cloud services.

Explain how containerization supports Hadoop workload migration to cloud-native environments.

Consider how containers help run applications anywhere.
