The AWS Cloud Adoption Framework (AWS CAF) cloud transformation journey is a four-phase process that helps customers plan and execute their cloud migration and digital transformation. The four phases are:

Envision phase: This phase focuses on demonstrating how cloud will help accelerate the business outcomes of the customer. It involves identifying and prioritizing transformation opportunities across four domains: business, people, governance, and platform. It also involves associating the transformation initiatives with key stakeholders and measurable business outcomes1.

Align phase: This phase focuses on identifying capability gaps across six perspectives: business, people, governance, platform, security, and operations. It also involves identifying cross-organizational dependencies and surfacing stakeholder concerns and challenges. The goal of this phase is to create strategies for improving the cloud readiness, ensure stakeholder alignment, and facilitate relevant organizational change management activities1.

Launch phase: This phase focuses on delivering pilot initiatives in production and demonstrating incremental business value. Pilots should be highly impactful and influence future direction. The customer should learn from the pilots and adjust their approach before scaling to full production1.

Scale phase: This phase focuses on expanding production pilots and business value to the desired scale and ensuring that the business benefits associated with the cloud investments are realized and sustained1.

Amazon EC2 Spot Instances are instances that use spare EC2 capacity that is available at up to a 90% discount compared to On-Demand prices. You can use Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, high-performance computing (HPC), and test & development workloads. Spot Instances are ideal for workloads that can be interrupted, such as batch image rendering applications1. On-Demand Instances are instances that let you pay for compute capacity by the hour or second (minimum of 60 seconds) with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs2. Reserved Instances are instances that provide you with a significant discount (up to 75%) compared to On-Demand Instance pricing. In exchange, you select a term and make an upfront payment to reserve a certain amount of compute capacity for that term3. Dedicated Instances are instances that run in a VPC on hardware that’s dedicated to a single customer. Your Dedicated Instances are physically isolated at the host hardware level from instances that belong to other AWS accounts4.

 C is correct because 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 example of an on-premises to hybrid migration. A hybrid cloud is a cloud computing environment that uses a mix of on-premises, private cloud, and public cloud services with orchestration between the platforms. A is incorrect because on-premises to cloud native migration is the process of moving a workload from a local data center to an architecture that is fully hosted and managed on the AWS Cloud. B is incorrect because hybrid to cloud native migration is the process of 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 on the AWS Cloud. D is incorrect because cloud native to hybrid migration is the process of moving a workload from an architecture that is fully hosted and managed on the AWS Cloud to an architecture that is distributed between the local data center and the AWS Cloud.

When a company moves from on-premises IT architecture to the AWS Cloud, it gains several benefits:

A. Reduced or eliminated tasks for hardware troubleshooting, capacity planning, and procurement: In an on-premises environment, companies must maintain their own hardware, which involves procuring servers, configuring them, managing capacity, and troubleshooting hardware failures. Moving to the AWS Cloud eliminates or greatly reduces these tasks since AWS is responsible for the underlying infrastructure.

E. Faster deployment of new features and applications: AWS provides scalable resources and automation tools that allow companies to deploy applications faster. Services like AWS Elastic Beanstalk, AWS CloudFormation, and AWS Lambda help streamline the deployment process, enabling quicker time-to-market for new features and applications.

Why other options are not suitable:

B. Elimination of the need for trained IT staff: While the cloud reduces certain operational burdens, it does not eliminate the need for skilled IT professionals to manage cloud services, ensure proper configurations, handle security, and manage applications.

C. Automatic security configuration of all applications that are migrated to the cloud: AWS provides security tools and services, but security configurations and management still require input from the customer to tailor them to specific application requirements.

D. Elimination of the need for disaster recovery planning: While AWS offers robust disaster recovery options, companies must still plan and implement disaster recovery strategies, such as backups and multi-region deployments.
