• Supply chains in software development can be complex and extend beyond the software factory, requiring collection and storage of metadata about artifacts and validation of signed artifacts backed by transparency log technologies.
• Behavior analysis and reproducible builds are recommended for ensuring the security of the build stage in the pipeline.
• CNCf projects like In Toto and Notary can be used to sign metadata and final software artifacts for deployment and distribution.
• Key material generation using technologies like SPIFFY can help minimize the attack surface and window for compromise.
• The presentation calls for community participation in the Secure Supply Chain Working Group to develop a reference architecture and framework of common tools and templates.
• An anecdote is not provided.

• CDI is a solution to the problem of fragmented device support in the cloud space
• CDI is based on the CNI model and describes the devices available in the machine and the operations the runtimes perform
• CDI aims to provide a uniform experience and the same set of features across different projects
• CDI has a roadmap for implementation and is working towards having support from at least two major runtimes and three different plugins
• CDI is a new and exciting group that welcomes contributions and feedback

• Cloud Events is a project that aims to standardize event data formats and protocols
• It includes SDKs for different languages and transports like HTTP, MQP, MQTT, Kafka, and NUTS
• The project includes specifications for discovery, subscription, and schema registry APIs
• The discovery API allows dynamic querying of producers and sources to understand emitted events
• The subscription API enables automation of event subscriptions
• The schema registry defines how to consume and publish schemas publicly or privately
• Cloud Events has the potential to simplify communication between systems and companies with a common way of subscribing to events

• The demo shows how to use a copy of production data to create a test or dev instance of a containerized application
• The storage platform used is PowerMax with the container storage interface
• GitLab is used for DevOps automation
• The persistent storage claim is dynamically allocated based on the application instance tag variable
• Non-production instances use a snapshot of the production volume for their own persistent volume
• The same workflow can be used for other Dell EMC storage platforms
• The presentation also demonstrates how Dell EMC PowerStore can be used to deploy containerized applications on VMware's Tanzu Kubernetes Grid
• Multiple virtual volumes are created for different types of data
• Persistent storage is presented through the VMware CSI driver

• Kubernetes is being used to support stateful applications, including databases, but there are challenges around data persistence and business continuity in multi-cloud environments
• Containers are different from VMs and require a different approach to support applications and their data
• Automating backend storage configuration and managing cloud native applications and persistent data from multi-cloud Kubernetes clusters from a single pane of glass is key to addressing these challenges
• NetApp's solution allows for easy snapshot, backup, clone and migration of applications with their data to another Kubernetes cluster

• Install the OpenShift GitOps operator to install ArgoCD and Tekton for use in CI/CD pipelines
• Customize the ArgoCD instance to ignore routes and set up an OpenShift policy to allow access to the application
• Install Seal Secrets to decrypt secrets uploaded in the Git repo
• Set up a webhook to trigger a Tekton pipeline when a commit is made to a specific branch
• Illustrate the pipeline process by making a change to the code and showing how ArgoCD automatically syncs the new image to the dev environment
• Submit a PR instead of automatically pushing changes to production

• The idea of CronJob API was introduced in Kubernetes in 2015.
• The initial implementation of the scheduled job controller was challenging due to the lack of API groups and versions.
• The old controller had performance and scaling issues when handling thousands of cron jobs.
• The new controller solved these issues and introduced new features such as a histogram metrics and minor optimizations.
• The new controller was tested with a sample workload of 6120 cron jobs and showed no visible delay in scheduling.
• The presentation expresses gratitude towards the users and developers who contributed to the development of the CronJob API.
