Lesson 7: Managing Cloud Migrations and Troubleshooting Cloud Deployments
What criteria should you use to determine if an application is a cloud migration candidate under the rehost or replatform migration types?
If the application is cloud ready or cloud ready with only some modification
Your organization has remote branch offices with poor Internet connectivity. The offices do store large quantities of data that must be migrated to the cloud. What is the best migration option in this scenario?
Data can be migrated to the cloud by using physical devices.
The cloud administrators at your organization currently follow an SOP checklist to build VM instances manually. There are still inconsistencies and the instance creation process can take too long. Suggest a solution to address both issues.
Instances could be constructed using templates instead of an SOP. Scripting and automation tools could also be used. Both solutions would increase deployment speed.
Users are reporting that they are unable to connect with the organization's cloud resources. What items should the administrator check?
Is the CSP experiencing a network outage? Is the organization's ISP experiencing a network outage?
Workstations in one segment of the on-premises network cannot reach services in other parts of the on-premises network or the cloud. What is the first device type to check?
Local network devices connecting that segment to the rest of the business network
Which migration phase are you in if you're attempting to manage the cost effectiveness of an existing cloud deployment?
Optimization
A cloud architect plans a big migration for a company that wants to keep the migration fast and easy. Which migration type would be the most applicable type of migration?
Rehosting
An administrator is evaluating an application for migration to the cloud and determines that before migrating the application, the organization must first send it back to the developers to remove hard-coded IP addresses and make other minor modifications. What cloud migration type does this represent?
Replatform
During the organization's cloud migration, you have identified a legacy application that is not well-suited to a cloud deployment. Many other cloud-ready applications exist that accomplish the same tasks. What migration type should you recommend?
Repurchase, or "drop and shop"
Give a reason that a service or application might be migrated from the cloud back to an on-premises deployment.
Several reasons exist: The service or app may not be benefiting from cloud characteristics, security regulations may forbid a public cloud deployment, the cost of hosting the app in the cloud may be too high, or the organization is redesigning it's cloud solution.
An application that runs in a container is not available. You've already confirmed the server hosting the container is running. What other components should you verify?
Verify that the container engine is running, that the container image is correct, that the container itself is running, and that the host system is providing enough resources to the container.
