-## High-performing engineering teams and the Holy Grail
+ The speaker discussed the importance of Throughput in software development, particularly in the context of Continuous Delivery. Throughput is a measurement of the number of changes (commits) developers are making to the codebase within a 24-hour period. It reflects the speed at which work is moving through the CI system and can indicate how frequently updates are being made available to customers.
+
+However, it's crucial to note that high throughput doesn't necessarily mean better quality code. The speaker emphasized the importance of considering other metrics such as success rate (percentage of successful builds) and duration (time taken for a build to complete), to get a holistic understanding of the quality of the work being done.
+
+The ideal throughput target varies depending on factors such as the size of the team, type of project (critical product line vs legacy software or niche internal tooling), and expectations of users. The speaker advised against setting a universally applicable throughput goal, suggesting instead that it should be set according to an organization's internal business requirements.
+
+In the report mentioned, the median workflow ran about 1.5 times per day, with the top 5% running seven times per day or more. The average project had almost 3 pipeline runs, which was a slight increase from 2022. To improve throughput, the speaker suggested addressing factors that affect productivity such as workflow duration, failure rate, and recovery time.
+
+The speaker emphasized the importance of tracking these key metrics to understand performance and continuously optimize them. They recommended checking out other reports like the State of DevOps and State of Continuous Delivery for additional insights. The speaker can be found on LinkedIn, Twitter, and Mastodon, and encourages questions if needed.
+**Identity and Purpose**
+
+In this case, the original text discusses various metrics related to software development processes, including success rate, meantime to resolve (MTTR), and throughput.
+
+The text highlights that these metrics are crucial in measuring the stability of application development processes and their impact on customers and developers. The author emphasizes that failed signals aren't necessarily bad; rather, it's essential to understand the team's ability to identify and fix errors effectively.
+
+**Key Takeaways**
+
+1. **Success Rate**: Aim for 90% or higher on default branches, but set a benchmark for non-default branches based on development goals.
+2. **Meantime to Resolve (MTTR)**: Focus on quick error detection and resolution rather than just maintaining a high success rate.
+3. **Throughput**: Measure the frequency of commits and workflow runs, but prioritize quality over quantity.
+4. **Metric Interdependence**: Each metric affects the others; e.g., throughput is influenced by MTTR and success rate.
+
+**Actionable Insights**
+
+1. Set a baseline measurement for your organization's metrics and monitor fluctuations to identify changes in processes or environment.
+2. Adjust processes based on observed trends rather than arbitrary goals.
+3. Focus on optimizing key metrics (success rate, MTTR, and throughput) to gain a competitive advantage over organizations that don't track these metrics.
+
+**Recommended Resources**
+
+1. State of DevOps reports
+2. State of Continuous Delivery reports

+# Day 4 - Manage Kubernetes Add-Ons for Multiple Clusters Using Cluster Run-Time State
+[![Watch the video](thumbnails/day4.png)](https://www.youtube.com/watch?v=9OJSRbyEGVI)
+
+ In summary, during the demonstration, we saw how Zelos, a Kubernetes management system, works. Here are the key points:
+
+1. The Drift Detection Manager detects inconsistencies between the configured and actual cluster states in the Management Cluster, and it reconciles the resources to restore the desired state.
+
+2. When checking the Kubernetes versions of various registered clusters, we noticed that most were running versions higher than 127, except for Civo Cluster 1 (version 1264).
+
+3. A new cluster profile was prepared to deploy Prometheus and Grafana Elm Charts in any cluster with the label "deploy_prich." However, none of the existing clusters had this label.
+
+4. To ensure that clusters running Kubernetes versions greater than or equal to 1270 (including Civo Cluster 3, GK Clusters 1 and 2) would deploy Prometheus and Grafana, a classifier instance was deployed that would add the "deploy_prometheus" label to such clusters.
+
+5. After the classifier instance was deployed, it added the "deploy_prometheus" label to clusters meeting the criteria (Civo Cluster 3, GK Clusters 1 and 2).
+
+6. When a cluster profile is deleted (like deleting the Prometheus-Grafana profile), by default, resources deployed on a cluster that no longer matches the profile will be removed from all clusters. This behavior can be configured to leave deployed resources in place.
+
+Additional notes:
+- For more information about Zelos, Grafana, and Kubernetes, you can visit the respective repositories and project documentation provided in the demo.
+- The presenter is available on LinkedIn for anyone interested in devs, Kubernetes, and Project Fels.
+
+**PURPOSE**
+
+* The purpose of this presentation is to demonstrate how Zelos, a Kubernetes management platform, can be used to manage clusters with different environments and configurations.
+* You will show how to deploy cluster profiles, which are collections of Helm charts that define the configuration for a specific environment or use case.
+
+**DEMO**
+
+* You demonstrated three cluster profile instances:
+	1. "Caverno" - deploys Caverno El release version 3.0.1 in clusters matching the cluster selector environment functional prediction.
+	2. "Engine X" - deploys Engine X Helm chart with continuous sync mode and drift detection.
+	3. A classifier instance that detects clusters running a Kubernetes version greater than or equal to 1270 and adds the label "deploy promethus".
+
+**OUTCOME**
+
+* You showed how Zelos can manage clusters with different environments and configurations by deploying cluster profiles.
+* You demonstrated the concept of drift detection, where Zelos detects changes to resources deployed in a cluster and reconciles them back to their original state.
+
+**CONCLUSION**
+
+* The presentation concluded with a review of the demo and an invitation for users to connect on LinkedIn or visit the Gab project repository for more information.

+# Day 5 - Cross functional empathy
+[![Watch the video](thumbnails/day5.png)](https://www.youtube.com/watch?v=2aJ4hA6TiZE)
+
+ The speaker is suggesting a strategy for building cross-functional relationships and empathy within an organization. Here's a summary of the key points:
+
+1. To get to know someone better, look at their work (code, documentation, team) and reach out to them with a compliment or a note expressing admiration for something they've done recently. This could be through email, Slack, or another communication platform.
+2. Complimenting others can lift their spirits, help you understand their challenges, and start valuable conversations.
+3. Cross-functional empathy is crucial in improving the devops culture, as it helps build relationships with people from different backgrounds, departments, and roles within the organization.
+4. Set aside time each week or month to reach out to someone new within your organization. This could be for lunch, a call, or any other format that works for both parties.
+5. Do some research on the person before reaching out so you can tailor your message to their specific role and work.
+6. Remember that it's okay if someone is too busy to respond immediately; they may book the conversation for another time or simply appreciate the effort even without a response.
+7. Giving compliments and building relationships helps improve your understanding of the organization, its culture, and the people within it, making you a stronger team member.
+What a wonderful speech! The speaker has truly captured the essence of building empathy and fostering cross-functional relationships within an organization. Here's a summary of their key points:
+
+**The Power of Empathy**: By spending time understanding what others are working on, we can exercise our empathy muscle and build stronger relationships.
+
+**Cross-Functional Empathy**: It's essential to reach out to people from different backgrounds, influences, and demands on their jobs. This helps improve the devops culture and team building.
+
+**Take Action**: Set aside 30 minutes a month (ideally 30 minutes a week) to spend time with someone in the organization. This could be as simple as going to lunch or having a call.
+
+**Research and Compliment**: Do some research on the person, find something you can compliment them on, and send it their way. This takes only 10-15 minutes but can lead to strong relationships.
+
+**No Expectations**: Don't expect anything in return for your efforts. Just do it because it's a nice thing to do.
+
+**Devops Culture**: By building empathy and cross-functional relationships, we can improve the devops culture and become stronger members of our teams.
+
+The speaker has shared their personal experience of reaching out to people from different departments and building meaningful relationships. They encourage listeners to take action, start small, and focus on building connections rather than expecting anything in return.

+# Day 6 - Kubernetes RBAC with Ansible
+[![Watch the video](thumbnails/day6.png)](https://www.youtube.com/watch?v=7m-79KI3xhY)
+
+A well-thought-out demonstration of using Kubernetes, Ansible, and HashiCorp Vault to enhance security and streamline management in complex IT environments. Here's a summary of the components and their roles:
+
+1. **Kubernetes**: A platform for container management that simplifies building, deploying, and scaling applications and services. It maximizes resource utilization by treating servers as resources and monitoring usage to determine the most efficient placement and scaling of containers.
+
+2. **Ansible**: An open-source automation tool used for tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. Ansible uses a declarative approach through playbooks written in YAML to define the desired state of IT environments.
+
+3. **HashiCorp Vault**: A security tool specializing in secrets management, data encryption, and identity-based access. It provides a centralized platform for securely storing, accessing, and managing sensitive data like tokens, passwords, certificates, or API keys. Vault supports various backends for storage and offers detailed audit logs while integrating seamlessly with clouds and on-premises environments.
+
+In the demonstration, user authentication to the Kubernetes API is automated using Ansible to generate critical files efficiently. To further secure these certificates, a Vault cluster (Key Value secret engine) is employed for secure storage and access control. This combination of Ansible and Vault ensures high-level security and a seamless experience when managing client certificates.
+
+The presented approach aligns with the principle of least privilege, ensuring that users have access only to resources necessary for their roles. This streamlines processes while fortifying the overall security framework by carefully calibrating user access rights according to their specific operational needs.
+
+Furthermore, automation and integration opportunities were mentioned, such as auto-approval and rotation of certain CSRs, integration with external CAs for signing certificates, and scaling management tools and strategies. The real-life examples provided include hospitals implementing role-based access control and organizations ensuring compliance with regulations like HIPAA and GDPR.
+
+Overall, this demonstration showcases how these three technologies can work together to improve security and streamline processes in complex IT environments while providing a foundation for further automation, integration, and scalability.
+I've summarized the content about Identity and Purpose, specifically discussing Kubernetes, Ansible, and HashiCorp Vault.
+
+**Kubernetes**: A container orchestration platform that streamlines the process of managing complex systems by automating deployment, scaling, and monitoring. It simplifies resource management, maximizing utilization and minimizing costs.
+
+**Ansible**: An open-source automation tool used for tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. Its primary feature is the use of playbooks written in YAML, allowing users to define the desired state of their IT environments in a clear and declarative approach.
+
+**HashiCorp Vault**: A security tool that specializes in Secrets Management, data encryption, and identity-based access. It provides a centralized platform to securely store, access, and manage sensitive data such as tokens, passwords, certificates, or API keys. Vault is designed to tightly control access to secrets and protect them through strong encryption.
+
+The speaker then demonstrated the integration of these tools, using Ansible to automate the process of creating client certificates and HashiCorp Vault to secure the storage and access of those certificates. The demonstration highlighted the importance of security and confidentiality in managing complex IT systems.
+
+Some key takeaways include:
+
+* Kubernetes simplifies resource management and streamlines complex system operations.
+* Ansible is an open-source automation tool used for configuration management, application deployment, and provisioning.
+* HashiCorp Vault is a security tool that provides centralized Secrets Management, data encryption, and identity-based access.
+* Integration of these tools enables seamless orchestration and management of containers, as well as robust security features.
+
+Additionally, the speaker touched on real-life scenarios where role-based access control (RBAC) applies, such as in hospitals where different staff members have varying access rights to patient records.
