In software engineering, there is a direct correlation between team performance and building robust, stable applications. The data community aims to adopt the rigorous engineering principles commonly used in software development into their own practices, which includes systematic approaches to design, development, testing, and maintenance. This requires carefully combining applications and metrics to provide complete awareness, accuracy, and control. It means evaluating all aspects of a team’s performance, with a focus on continuous improvement, and it applies just as much to mainframe as it does to distributed and cloud environments—maybe more.

This is achieved through practices like infrastructure as code (IaC) for deployments, automated testing, application observability, and complete application lifecycle ownership. Through years of research, the DevOps Research and Assessment (DORA) team has identified four key metrics that indicate the performance of a software development team:

• Deployment frequency – How often an organization successfully releases to production
• Lead time for changes – The amount of time it takes a commit to get into production
• Change failure rate – The percentage of deployments causing a failure in production
• Time to restore service – How long it takes an organization to recover from a failure in production

These metrics provide a quantitative way to measure the effectiveness and efficiency of DevOps practices. Although much of the focus around analysis of DevOps is on distributed and cloud technologies, the mainframe still maintains a unique and powerful position, and it can use the DORA 4 metrics to further its reputation as the engine of commerce.

This blog post discusses how BMC Software added AWS Generative AI capabilities to its product BMC AMI zAdviser Enterprise. The zAdviser uses Amazon Berggrunnur to provide summarization, analysis, and recommendations for improvement based on the DORA metrics data.

Challenges of tracking DORA 4 metrics

Tracking DORA 4 metrics means putting the numbers together and placing them on a dashboard. However, measuring productivity is essentially measuring the performance of individuals, which can make them feel scrutinized. This situation might necessitate a shift in organizational culture to focus on collective achievements and emphasize that automation tools enhance the developer experience.

It’s also vital to avoid focusing on irrelevant metrics or excessively tracking data. The essence of DORA metrics is to distill information into a core set of key performance indicators (KPIs) for evaluation. Mean time to restore (MTTR) is often the simplest KPI to track—most organizations use tools like BMC Helix ITSM or others that record events and issue tracking.

Capturing lead time for changes and change failure rate can be more challenging, especially on mainframes. Lead time for changes and change failure rate KPIs aggregate data from code commits, log files, and automated test results. Using a Git-based SCM pulls these insight together seamlessly. Mainframe teams using BMC’s Git-based DevOps platform, AMI DevX ,can collect this data as easily as distributed teams can.

Amazon Bedrock is a fully managed service that offers a choice of high-performing foundation models (FMs) from leading AI companies like AI21 Labs, Anthropic, Cohere, Meta, Stability AI, and Amazon via a single API, along with a broad set of capabilities you need to build generative AI applications with security, privacy, and responsible AI.

BMC AMI zAdviser Enterprise provides a wide range of DevOps KPIs to optimize mainframe development and enable teams to proactvely identify and resolve issues. Using machine learning, AMI zAdviser monitors mainframe build, test and deploy functions across DevOps tool chains and then offers AI-led recommendations for continuous improvement. In addition to capturing and reporting on development KPIs, zAdviser captures data on how the BMC DevX products are adopted and used. This includes the number of programs that were debugged, the outcome of testing efforts using the DevX testing tools, and many other data points. These additional data points can provide deeper insight into the development KPIs, including the DORA metrics, and may be used in future generative AI efforts with Amazon Bedrock.

The following architecture diagram shows the final implementation of zAdviser Enterprise utilizing generative AI to provide summarization, analysis, and recommendations for improvement based on the DORA metrics KPI data.

1. Create the aggregation query to retrieve the metrics from Elasticsearch.
2. Extract the stored mainframe metrics data from zAdviser, which is hosted in Amazon Elastic Compute Cloud (Amazon EC2) and deployed in AWS.
3. Aggregate the data retrieved from Elasticsearch and form the prompt for the generative AI Amazon Bedrock API call.
4. Pass the generative AI prompt to Amazon Bedrock (using Anthropic’s Claude2 model on Amazon Bedrock).
5. Store the response from Amazon Bedrock (an HTML-formatted document) in Amazon einföld geymsluþjónusta (Amazon S3).
6. Trigger the KPI email process via AWS Lambda:
   1. The HTML-formatted email is extracted from Amazon S3 and added to the body of the email.
   2. The PDF for customer KPIs is extracted from zAdviser and attached to the email.
   3. The email is sent to subscribers.

The following screenshot shows the LLM summarization of DORA metrics generated using Amazon Bedrock and sent as an email to the customer, with a PDF attachment that contains the DORA metrics KPI dashboard report by zAdviser.

In this solution, you don’t need to worry about your data being exposed on the internet when sent to an AI client. The API call to Amazon Bedrock doesn’t contain any personally identifiable information (PII) or any data that could identify a customer. The only data transmitted consists of numerical values in the form of the DORA metric KPIs and instructions for the generative AI’s operations. Importantly, the generative AI client does not retain, learn from, or cache this data.

The zAdviser engineering team was successful in rapidly implementing this feature within a short time span. The rapid progress was facilitated by zAdviser’s substantial investment in AWS services and, importantly, the ease of using Amazon Bedrock via API calls. This underscores the transformative power of generative AI technology embodied in the Amazon Bedrock API. This API, equipped with the industry-specific knowledge repository zAdviser Enterprise and customized with continuously collected organization-specific DevOps metrics, demonstrates the potential of AI in this field.

Generative AI has the potential to lower the barrier to entry to build AI-driven organizations. Large language models (LLMs) in particular can bring tremendous value to enterprises seeking to explore and use unstructured data. Beyond chatbots, LLMs can be used in a variety of tasks, such as classification, editing, and summarization.
