About EROAD EROAD is a New Zealand technology and road services business that sells hardware and software that can monitor commercial vehicles and collect road-user charges electronically, replacing paper-based systems.

The fleet tolling system comprises a secure on-board unit for vehicles and a secure web transaction gateway to collect road user charges and provide value-added services such as fleet and fuel management, messaging and off-road reports. Figure 1 below shows how the service works.

The Auckland-based company has employees in offices in New Zealand, North America and Australia and is now a global technology player.

Expanding into Australia and North America soon outstripped hardware capacity and prompted the company to review its infrastructure options. EROAD considered purchasing more hardware, but that option would require annual hardware purchases and infrastructure upgrades at considerable capital and operational cost.

However, establishing a co-located disaster recovery environment over multiple locations would be prohibitively expensive and time-consuming for EROAD to maintain.

The service later moved into full production following an independent audit of its Weight-Mile Tax solution by the Oregon Secretary of State Audits Division. At that point, the organization then decided to move its entire environment to AWS.

Elastic Load Balancing automatically distributes traffic across the Amazon EC2 instances to ensure no single instance is overused. Amazon Route 53 manages public-facing domain name services records and ensures the services backing them are operating properly.

EROAD uses Amazon VPC helps to control all elements of its virtual network, including placing its internal databases and application servers in private subnets not accessible from the internet.

The firm uses network access control lists and security groups to control access to individual Amazon EC2 instances, and running virtual private networks from its AWS environments to partners such as Vodafone. EROAD scales up and down daily to meet demand. The firm has also pulled a large number of data sources into the Amazon Redshift managed data warehouse service with Amazon S3 as the basis of a Tableau analytics visualization service for its customers.

If a change is required, EROAD can adjust the stack template or Chef recipe to roll it out through the environments using its standard release pipeline. The company uses a combination of Amazon CloudWatchthe Sensu open source monitoring framework, the Graphite storage engine and the Grafana dashboard and graph editor for monitoring.

The cloud also supports responses to each update such as checking whether the vehicle is subject to a road user charge or tax, or needs a service. The AWS Cloud delivered Life Application Study Bible NLT, Large Print [Tyndale] on timberdesignmag.com *FREE* shipping on qualifying offers.
