Question

A user is moving a workload from a local data center to an architecture that is distributed between the local data center and the AWS Cloud. Which type of migration is this?

A. On-premises to cloud native
B. Hybrid to cloud native
C. On-premises to hybrid
D. Cloud native to hybrid

Answer

C. On-premises to hybrid

Explanation

The correct answer is C. On-premises to hybrid.

An on-premises to hybrid migration is a type of migration that involves moving a workload from a local data center to an architecture that is distributed between the local data center and the AWS Cloud. This means that some components of the workload remain on-premises, while others are migrated to the cloud. For example, a user may migrate their web servers and databases to AWS, while keeping their authentication and authorization servers on-premises.

An on-premises to hybrid migration can offer several benefits, such as:

  • Scalability: The user can leverage the elasticity and flexibility of the AWS Cloud to scale their workload up or down as needed, without having to invest in additional hardware or infrastructure on-premises.
  • Cost-efficiency: The user can reduce their operational and maintenance costs by paying only for the resources they use in the cloud, while retaining control over their existing assets on-premises.
  • Performance: The user can improve the performance and availability of their workload by using AWS services and features, such as load balancing, caching, content delivery network, and edge locations.
  • Security: The user can enhance the security and compliance of their workload by using AWS security tools and best practices, such as encryption, firewall, identity and access management, and auditing.

The other options are incorrect because:

  • Option A is incorrect because an on-premises to cloud native migration is a type of migration that involves moving a workload from a local data center to an architecture that is fully hosted and managed in the AWS Cloud. This means that all components of the workload are migrated to the cloud and optimized for cloud performance and scalability.
  • Option B is incorrect because a hybrid to cloud native migration is a type of migration that involves moving a workload from an architecture that is distributed between the local data center and the AWS Cloud to an architecture that is fully hosted and managed in the AWS Cloud. This means that the remaining components of the workload that are on-premises are migrated to the cloud and optimized for cloud performance and scalability.
  • Option D is incorrect because a cloud native to hybrid migration is a type of migration that involves moving a workload from an architecture that is fully hosted and managed in the AWS Cloud to an architecture that is distributed between the local data center and the AWS Cloud. This means that some components of the workload are moved back to on-premises, while others remain in the cloud.

Therefore, the only type of migration that matches the scenario of moving a workload from a local data center to an architecture that is distributed between the local data center and the AWS Cloud is an on-premises to hybrid migration.
