A fundamental component of the Operational Excellence pillar of the AWS Well-Architected Framework is evolving your environment, incorporating continuous improvement over time.

Moving to the cloud should be transformational for a business, by adding agility, and making it easier to innovate. It’s important to remember the innovations are often small, incremental in nature, and designed to solve a “legacy” problem from an on-premises environment.

DXC Technology, an AWS Premier Consulting Partner, identified one such improvement opportunity—by integrating their ServiceNow instances with AWS Support, they could accelerate ticket resolution via automating ticket processing.

DXC serves more than 6,000 customers in 70 countries, and as an AWS Managed Service Provider (MSP) needs seamless integration for ticketing, support, and two-way communication to provide world-class customer service to clients.

The guiding tenets for this work focused on the Well-Architected Framework—incorporating design principles such as performing operations as code; operational health metrics such as time to close a ticket; and the aforementioned evolution.

All of this allowed DXC to simplify work for customers inside and outside the organization. An added benefit for MSPs like DXC is the API-driven integration to AWS Support contributes to the AWS MSP audit and review.

This post explains the previous environment, the old customer service workflow, and how the work was done to integrate ServiceNow and AWS Support. Finally, we’ll share the successes DXC achieved within the current environment.

Pre-Integration Architecture

As a service provider, DXC frees up client resources from platform work via such things as automation, managed services, and environment provisioning; this allows their customers to focus on higher value work in the application stack.

The AWS Well-Architected Framework identifies various models of separating responsibilities between the end customer, a service provider like DXC, and AWS. The different models require support interactions between the three entities to varying degrees. In our current situation, AWS is responsible for the platform, DXC provides managed services, and the client focuses on their business applications.

AWS refers to this as a Separated Application Engineering and Operations (AEO), and Infrastructure Engineering and Operations (IEO) with Central Governance and a Service Provider model in the Well-Architected Framework. The support structure is detailed below.

The end client is responsible for the yellow area in the diagram above, while DXC is responsible for the red area, and AWS performs work within the blue area.

If there’s a disruption to service availability, clients need to be able to diagnose and remedy problems at the application level, and communicate platform disruptions to DXC. Meanwhile, DXC needs to be able to isolate any disruption at the service or platform level in conjunction with AWS.

The common thread tying this all together is the ServiceNow ticketing system, allowing communication between the three layers as a central repository for incident reference.

Original Workflow Process

Prior to integrating ServiceNow with AWS Support, the DXC operational technicians followed a manual process. Problems were recorded in ServiceNow, and an AWS case would be opened via web, chat, or phone, depending upon severity.

If an AWS Technical Account Manager (TAM) was required, that was another process and conducted via email most of the time. There was little to no automation in this process, and multiple opportunities for failure instead of being a reliable mechanism (see figure 2).

Recognizing there was an opportunity to improve on this process, DXC initiated an internal review, starting with their customer base and working backwards to a solution.

Clients may have multiple AWS accounts, some of which may not be managed by DXC, in addition to those that are. Clients may also have their own instances of ServiceNow that would require integration with the DXC ServiceNow environment.

DXC narrowed the options to improve the service provision process to the following three:

  • Applying Lean techniques to the manual process. While some improvements could be realized here, not enough value would be gained with this approach.
  • Use an existing ServiceNow plugin to accomplish the integration; after review of what was on the market, nothing met DXC’s needs.
  • Build a bespoke solution that any DXC organization could utilize when needing to exchange tickets with AWS. This solution would meet the needs of the DXC Cloud Operations team, and it was scalable to other teams within DXC’s global footprint.

Integration Architecture and Work

Once the path forward to create a leveraged integration solution was made, the DXC development team created user stories, set out the project plan, and divided the work into two sprints. System integration, and testing was scheduled with AWS Support following those sprints.

Recognizing the variable demand for this solution, the development team based the solution around AWS serverless options, starting with AWS Lambda and using AWS Step Functions to sequence the Lambda stages.

DXC designed an Integration Adapter for AWS Support, utilizing widely available AWS services such as Amazon API Gateway, Amazon CloudWatch, Amazon Simple Notification Service (SNS), and Amazon Simple Storage Service (Amazon S3), among other services. This was done to ensure scalability within DXC’s other lines and business, and to make it replicable via consulting engagements for other DXC clients who are facing similar challenges.

After the initial build was tested within the DXC systems, the next two weeks were dedicated to testing integration with AWS Support, and was completed with the assistance of the TAM on the DXC account team.

Architecture

The technical solution leverages features of ServiceNow to facilitate the communication. As examples, it uses the Standard Incident eBond Interface as the foundation to build a Partner-Group style eBond (bi-directional integration) between DXC and AWS.

Flows are built in ServiceRamp in the CSC-SP Tenant using ConnectNow and the Integration Adapter for AWS as endpoints. This allows for asynchronous communication between the support groups, which facilitates ticket resolution when support groups may be geographically dispersed.

Outbound interactions from DXC to AWS are event-driven. Updates made in ServiceNow are fed to AWS in near real-time, and translate into create or update actions performed by the Integration Adapter for AWS against the appropriate AWS account.

Inbound transactions from AWS to DXC are schedule-driven. New or updated cases in AWS Support Center are discovered based on a polling cycle, and are translated into create or update actions performed by the Platform-DXC Incident Capability inside ConnectNow. The polling cycle is set at a five-minute interval.

New Workflow Process

The figures below provide a comparison of the previous and current processes. In the original process, note multiple manual steps (creating, resolving, closing tickets) and lack of integrated reporting against the SLA.

The automated communication was unidirectional (AWS notifications picked up by eBonding, but not the reverse), which meant that work completed by DXC had to be communicated to AWS Support separately. This could lead to delays in resolution, while waiting on updates for troubleshooting and resolution.

The new process automates creating, updating, and closing tickets based on the status provided by AWS or the DXC CloudOps team. The next figure shows the new incident management workflow, including automated ticketing process, as well as bidirectional communication between the teams.

Automating updates allows for services teams on both sides to quickly see the status of a ticket as well as next steps in the system. In addition, automatically closing tickets at resolution eliminates a manual process that adds no business value, but can create reporting issues if a ticket is accidentally left open.

Outcomes and Rewards

After completing this build in late 2020, DXC has used this in daily operations. Through the first half of 2021, there were an average of 40 cases per month, across all severities.

The automated interaction between AWS Support teams and the CloudOps engineer from DXC has helped with greater awareness of issues, regular updates on the tickets, and more accurate resolution estimates. All of the tickets this year have been resolved within the service level agreement (SLA), and the average resolution time is under 24 hours across all severities.

This new platform has led to quicker communication, and easier access to AWS technical expertise, combining for faster resolution for our mutual clients.

Conclusion

The cloud provides opportunities for businesses to be nimbler in how they interact with both customers and service partners. Using cloud best practices allows for faster innovation, and lowers risk when experiments fail, due the ease of spinning up low cost environments.

Automating processes can eliminate non-value-adding steps (such as closing out tickets), which benefits the company by lowering the risk of accidental omissions, and can expedite the most important tasks (like troubleshooting, communication).

A simple challenge of “how can we make an old process new again?” led to DXC leveraging best practices, innovating in-house, and greater customer service.
