Questions and Answers

Which migration strategy involves moving infrastructure without any changes?

Rebuild

Rehost (correct)

Refactor

Replace

What is a potential downside of using the 'lift and shift' migration approach?

It significantly delays the migration process.

It does not include any security features.

It does not allow organizations to access cloud-native services. (correct)

It requires extensive re-coding.

Why might some workloads be unsuitable for the cloud?

They involve highly dynamic data that suit cloud scalability.

They are already optimized for cloud-native services.

They operate adequately in cloud and local environments.

They may need compliance requirements that some cloud providers cannot meet. (correct)

Study Notes

Cloud Migration Risks

Wrong migration approach: Selecting a migration strategy that fails to meet business and security demands can have serious consequences.
Gartner's 5 migration strategies: Rehost, Refactor, Revise, Rebuild, and Replace, each with its pros and cons.
Rehost (Lift and Shift): Lifts infrastructure from original environment to new cloud environment without changes, simplifying and speeding up migration, but prevents leveraging cloud-native services and modernizing IT environment.

Incompatible Workloads

Not all workloads suited for cloud: Organizations that unilaterally move workloads to the cloud may face costly repatriation down the road.

Cloud Migration Challenges

Inadequate Migration Strategies

Migrating applications to the cloud without optimizing for cloud-native features and services can lead to inefficient use of resources
Failing to consider the complexity of the application and required changes for cloud deployment can result in poor performance and security issues

Unsuitable Workloads

Applications with high latency or real-time requirements may not be suitable for cloud migration due to limited control over infrastructure
Workloads requiring specialized hardware or software may not be compatible with cloud providers' offerings
Incompatible licensing models or unsupported operating systems can hinder cloud migration
Applications with tightly coupled components or complex integrations can be difficult to migrate

Hidden Dependencies

Failure to identify hidden dependencies on legacy systems or third-party services can lead to unexpected migration complexities
Dependencies on outdated technologies or unsupported platforms can cause migration failure
Overlooking dependencies on specific hardware or software configurations can result in application downtime

Cloud Security Misconceptions

Cloud providers are not responsible for all security aspects, and organizations must implement adequate security measures
Failing to implement identity and access management (IAM) controls can lead to unauthorized access to cloud resources
Overlooking data encryption and key management responsibilities can result in data breaches
Insufficient monitoring and logging for security incidents can leave systems vulnerable to attacks

Data Loss and Downtime Risks

Inadequate backup and disaster recovery strategies can result in data loss and extended downtime
Failure to implement high availability and redundancy measures can lead to service disruptions
Insufficient monitoring and alerting for potential issues can cause unexpected downtime
Lack of regular security patches and updates can leave systems vulnerable to attacks
