Question 3

Rehosting

Answer 3

also known as “lift-and-shift” involves moving applications without changes.

Question 4

Replatforming

Answer 4

also known as “lift, tinker, and shift,” involves making a few cloud optimizations to realize a tangible benefit. Optimization is achieved without changing the core architecture of the application

Question 5

Refactoring (aka re-architecting)

Answer 5

involves reimagining how an application is architected and developed by using cloud-native features. Refactoring is driven by a strong business need to add features, scale, or performance that would otherwise be difficult to achieve in the application’s existing environment

Question 6

Repurchasing

Answer 6

involves moving from a traditional license to a software-as-a-service model.

Question 7

Retaining

Answer 7

consists of keeping applications that are critical for the business in the source environment. This might include applications that require major refactoring before they can be migrated, or, work that can be postponed until a later time.

Question 8

Retiring

Answer 8

the process of removing applications that are no longer needed.

Answer 11

provides powerful computing resources for use cases such as machine learning, full motion video analysis, analytics, and local computing stacks.

Question 12

AWS Snowmobile

Answer 12

is an exabyte-scale data transfer service used to move large amounts of data to AWS. You can transfer up to 100 petabytes of data per Snowmobile, a 45-foot long ruggedized shipping container, pulled by a semi trailer truck.

Question 13

Serverless

Answer 13

serverless refers to applications that don’t require you to provision, maintain, or administer servers. You don’t need to worry about fault tolerance or availability. AWS handles these capabilities for you. AWS Lambda is an example of a service that you can use to run serverless applications. If you design your architecture to trigger Lambda functions to run your code, you can bypass the need to manage a fleet of servers.
