Achieving Low Latency and Jitter-Free Connectivity for Real-Time Services

Correct Answer - D.

AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from the organization's premises to AWS.

The service provides a dedicated network connection with one of the AWS Direct Connect locations.

It makes it possible to guaranteed high bandwidth and very low latency connectivity.

Option A is INCORRECT because the scenarios require a connectivity option.

But Amazon Kinesis Data Streams (KDS) is a massively scalable and durable real-time data streaming service.

It does not guarantee the quality of connectivity between the organizations on-premise infrastructure and the AWS cloud build.

The dataKDS collects is available in milliseconds to enable real-time analytics use cases such as real-time dashboards, real-time anomaly detection, dynamic pricing, and more.

Option B is INCORRECT because the organization requires a connectivity solution and not an application service.

Amazon Kinesis makes it easy to collect, process, and analyze real-time, streaming data to get timely insights and react quickly to new information.

Option C is INCORRECT because Amazon Kinesis Data Firehose is used to load streaming data into various destinations like data lakes, data stores and analytics tools.

However, the service does not guarantee link quality between the organization's on-premise infrastructure and the AWS cloud.

For an organization that requires connectivity with no jitter and very low latency between its on-premise infrastructure and its AWS cloud build to support live streaming and real-time services, the most appropriate solution would be D. AWS Direct Connect.

AWS Direct Connect is a dedicated network connection between an organization's on-premise infrastructure and AWS. This solution provides a reliable, high-performance connection with low latency and no jitter, making it ideal for real-time services and live streaming.

Direct Connect establishes a dedicated network connection from an organization's on-premises data center to AWS, which is routed over a private connection. The connection is established through a Direct Connect Partner, which could be an internet service provider, a colocation provider, or a network service provider.

This solution offers several benefits, including:

1. Improved Performance: Direct Connect provides a dedicated, private network connection that offers consistent network performance, low latency, and no jitter, which is essential for real-time services and live streaming.

2. Enhanced Security: Since the connection is private, it is more secure than a public internet connection. An organization can also use Direct Connect to establish a private connection to Amazon VPC, which offers additional security benefits.

3. Cost Savings: Since Direct Connect offers a dedicated connection, an organization can reduce its network costs by avoiding the costs associated with a public internet connection. It also eliminates the need for a VPN and associated hardware.

4. Scalability: Direct Connect provides scalable bandwidth options, which can be increased or decreased based on an organization's needs. This makes it easy to manage network resources and ensures that an organization has the capacity it needs to support its services.

Therefore, AWS Direct Connect is the most appropriate solution to meet an organization's requirements for connectivity with no jitter and very low latency between its on-premise infrastructure and its AWS cloud build to support live streaming and real-time services.
