Question
A global manufacturing company plans to migrate the majority of its applications to AWS. However, the company is concerned about applications that need to remain within a specific country or in the company’s central on-premises data center because of data regulatory requirements or requirements for latency of single-digit milliseconds. The company also is concerned about the applications that it hosts in some of its factory sites, where limited network infrastructure exists.
The company wants a consistent developer experience so that its developers can build applications once and deploy on premises, in the cloud, or in a hybrid architecture. The developers must be able to use the same tools, APIs, and services that are familiar to them. Which solution will provide a consistent hybrid experience to meet these requirements?
A. Migrate all applications to the closest AWS Region that is compliant. Set up an AWS Direct Connect connection between the central on-premises data center and AWS. Deploy a Direct Connect gateway.
B. Use AWS Snowball Edge Storage Optimized devices for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Retain the devices on premises. Deploy AWS Wavelength to host the workloads in the factory sites.
C. Install AWS Outposts for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Use AWS Snowball Edge Compute Optimized devices to host the workloads in the factory sites.
D. Migrate the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds to an AWS Local Zone. Deploy AWS Wavelength to host the workloads in the factory sites.
Answer
C. Install AWS Outposts for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Use AWS Snowball Edge Compute Optimized devices to host the workloads in the factory sites.
Explanation
The question you asked is about how to migrate the majority of applications to AWS for a global manufacturing company that has some applications that need to remain within a specific country or in the company’s central on-premises data center because of data regulatory requirements or requirements for latency of single-digit milliseconds. The company also has some applications that it hosts in some of its factory sites, where limited network infrastructure exists. The company wants a consistent developer experience so that its developers can build applications once and deploy on premises, in the cloud, or in a hybrid architecture. The solution that will provide a consistent hybrid experience to meet these requirements is C. Install AWS Outposts for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Use AWS Snowball Edge Compute Optimized devices to host the workloads in the factory sites.
AWS Outposts is a fully managed service that extends AWS infrastructure, services, APIs, and tools to virtually any data center, co-location space, or on-premises facility. You can use AWS Outposts to run your applications that require low latency or local data processing on premises while seamlessly connecting to the rest of your applications and services in the AWS Region. You can choose from a range of compute, storage, database, and networking options for your Outposts and use the same tools and APIs that you use for AWS.
AWS Snowball Edge is a physical device that provides edge computing and data transfer capabilities. You can use Snowball Edge devices to run applications at remote or disconnected locations where network bandwidth is limited or nonexistent. You can choose from different types of Snowball Edge devices depending on your use case: Storage Optimized devices provide high-capacity storage for data collection and migration; Compute Optimized devices provide additional compute power and GPU for edge processing; and Data Streaming devices provide high-speed data capture and processing for streaming workloads.
By using AWS Outposts and Snowball Edge devices, you can provide a consistent hybrid experience for your developers and users. You can use the same AWS services, tools, APIs, and SDKs to build and deploy your applications on premises or in the cloud. You can also use AWS services such as Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS), Amazon S3, Amazon DynamoDB, Amazon RDS, Amazon CloudFormation, AWS CloudTrail, and AWS CloudFormation to manage your hybrid environment.
The other options are not correct because:
A. Deploy an Amazon RDS Proxy layer in front of the DB instance. Store the connection credentials as a secret in AWS Secrets Manager. This option is not correct because it does not address the requirements for latency of single-digit milliseconds or local data processing for some applications. RDS Proxy is a fully managed database proxy service that sits between your application and your RDS database instance. It allows you to pool and share database connections among multiple application instances or containers, reducing connection overhead and improving performance and scalability. It also supports automatic failover to a standby instance in case of a primary instance failure. However, RDS Proxy does not reduce the network latency between your application and your database instance or enable local data processing on premises.
B. Use AWS Snowball Edge Storage Optimized devices for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Retain the devices on premises. Deploy AWS Wavelength to host the workloads in the factory sites. This option is not correct because it does not provide a consistent developer experience or leverage the full range of AWS services and tools. Snowball Edge Storage Optimized devices are designed for data collection and migration rather than edge computing. They have limited compute capabilities and support only a subset of AWS services such as Amazon EC2, Amazon S3, Amazon Lambda, Amazon DynamoDB Local, Amazon EBS Local Volumes, NFS Server Access Point (SAP), SMB Server Access Point (SAP), S3 Adapter Endpoint (S3E), IAM Local Users & Groups (IAM-LUG), Cluster Manager (CM), OpsHub UI (OHUI), Job Management API (JMAPI), File Gateway (FGW), Storage Gateway (SGW), DataSync Agent (DSA), Greengrass Core (GGC), Greengrass Group (GGG), Greengrass Device (GGD). Wavelength is a service that enables you to deploy applications that require ultra-low latency to mobile devices and end users by bringing AWS services to the edge of 5G networks. Wavelength is not suitable for factory sites where network infrastructure is limited or nonexistent.
D. Migrate the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds to an AWS Local Zone. Deploy AWS Wavelength to host the workloads in the factory sites. This option is not correct because it does not address the requirements for local data processing or network connectivity for some applications. A Local Zone is an extension of an AWS Region in close geographic proximity to your users. A Local Zone has its own connections to the internet and supports AWS Direct Connect. Resources that are created in a Local Zone can serve local users with low-latency communications. However, a Local Zone does not enable local data processing on premises if required by data regulatory requirements. Wavelength is a service that enables you to deploy applications that require ultra-low latency to mobile devices and end users by bringing AWS services to the edge of 5G networks. Wavelength is not suitable for factory sites where network infrastructure is limited or nonexistent.
