eBPF Summit October 28, 2020 Debugging Go in production using eBPF ABOUT ME ? i’m Zain @zainasgar Co-Founder/CEO Pixie (@pixie_run) & Adjunct Professor of CS @ Stanford DEVELOPER PROBLEM You’re Argument Tracer ● Utilizing tracepoints for dynamic logging allows for easy instrumentation of production binaries ● The complexities of the Go ABI make it difficult to do. Especially when you consider:

Splitting CI and CD 1.3. Promotion of releases between environments 1.4. Modeling multi-environment configurations 1.5. Auto-scaling and dynamic resources 1.6. GitOps rollbacks 1.7. Observability promotion of releases between environments 4. There is no standard practice for modeling multi-environment configurations 5. GitOps breaks down with auto-scaling and dynamic resources 6. There is no of GitOps. There are also several underlying issues such as not knowing exactly when your environment has finished with the deployment in order to trigger the tests. The same scenario is trivial

Focused on version control and automated environment creation – time reduced from 8 weeks to 1 day b. ENABLE ON-DEMAND CREATION OF DEV, TEST, AND PRODUCTION ENVRIONMENTS i. Major contributing cause behaves in a production-like environment ii. Don’t just document the environment specifications 1. Create a common build mechanism to create it on demand 2. Codified in automated environment build process everything, everything is checked into version control 1. Application code & dependencies 2. Environment scripts & creation tools 3. DB scripts and reference data 4. Containers 5. Automated tests

measure in the hundreds per day. It quickens developer loops so much that often, features land in production that same day. All the golden metrics you track will improve, and morale along with it. Christian central point of deciding what and how to operate on something. Kubernetes controls the operating environment by comparing the declared (desired) state of an object to the current running state. If these autohealing. If you declare that ten instances of your application should be running, but two fail in production, leaving only eight, your running state has drifted away from the desired state. If your DevOps

Paper Innovation Projects DPUDirect DPU SIG DPUDirect creates a collaborative operating environment for services, enabling them to be easily offloaded and ported between hosts and DPUs. The feature Network Attached Storage (NAS) become the most viable option for managing massive unstructured production services. Enhanced Network File System (eNFS) helps improve the performance and reliability of load balancing. eNFS: Building an E2E High-Performance and Reliable Distributed File System for Production Services Enhanced NFS protocol Native NFS protocol NFS One Socket Limited by the maximum NIC

kept under source control, diff tools and synchronization agents can compare what’s running in production with what’s under source control — and when a divergence is detected between the two, an alert specific cluster credentials to make a change to your system. With GitOps, there is a segregated environment, and the state definition lives outside of it. This allows your team to separate what they actually approach, the development team remains dependent on the operations team to deploy new changes in production. GitOps empowers teams to become more efficient and strategic. It enables development teams to

operations and automation forward by “light-years” and had performed huge number of production deployments. g. INJECT PRODUCTION FAILURES TO ENABLE RESILIENCE AND LEARNING i. Crumple zones in cars – build in issues away from critical areas. ii. Michael Nygard, author of Release It! Design and Deploy Production-Ready Software, “If you do not design your failure modes, then you will get whatever unpredictable—and operations influence components used in production or have the ability to not be responsible for unsupported platforms ii. Systematically review production infrastructure and services for items that
