Yan Cui on Serverless Orchestration & Choreography, Distributed Tracking, Cold Starts, and more Aug 31, 2020

Show notes

Today on the InfoQ Podcast, Yan Cui (a long time AWS Lambda user and consultant) and Wes Reisz discuss serverless architectures. The conversation starts by focusing on architectural patterns around choreography and orchestration. From there, the two move into updates on the current state of serverless cold start times, distributed tracing, and state.

Rancher on Hybrid Cloud, Kubernetes at the Edge, and Open Standards Jul 10, 2020

Show notes

In this podcast, Shannon Williams, co-founder and president at Rancher Labs and Darren Shepherd, co-founder and CTO at Rancher Labs sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: the adoption of hybrid cloud across organisations, the evolution of Kubernetes as a key abstraction for portability and cross-cloud security, running thousands of Kubernetes clusters at the edge, and the value of open standards. Why listen to this podcast - Organisations are adopting hybrid cloud strategies. The use of containers to package and run applications across clouds has seen large adoption over the past five years. Containers and Kubernetes are everywhere: the datacenter, the edge, embedded systems, and other locations. - Two enterprise use cases for Kubernetes stand out: providing standardised abstractions and APIs to increase portability across vendors and cloud platforms; and providing a framework and homogenised foundation on which to build and implement (cross cloud) security solutions. - Open standards support interoperability and drive innovation. The CNCF is becoming the natural home for open cloud technologies. The Rancher team have donated Longhorn, their cloud-native distributed storage platform for Kubernetes that was recently announced as generally available, to the CNCF. - With the success of lightweight Kubernetes distributions, such as Rancher’s K3s, engineers are starting to deploy standalone Kubernetes clusters “by the thousands” to edge locations. Rancher has recently released Fleet, a new open source project that is focused on managing large collections (“fleets”) of Kubernetes clusters. - Many developers and end users of Kubernetes simply want a platform-as-a-service (PaaS)-like experience. The next 12 months will see the community focus on the simplification of the Kubernetes ecosystem.

Nora Jones on Resilience Engineering, Mental Models, and Learning from Incidents Jul 03, 2020

Show notes

In this podcast, Nora Jones, Co-Founder and CEO at Jeli and co-author of O’Reilly’s “Chaos Engineering: System Resiliency in Practice”, sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: chaos engineering and resilience engineering, planning and running effective chaos experiments, and learning from incidents. Why listen to this podcast: - The chaos engineering and resilience engineering fields, although inextricably linked, are often incorrectly conflated. Resilience engineering is focused on “identifying and then enhancing the positive capabilities of people in organizations that allow them to adapt effectively and safely under varying circumstances.” - The UX of internal or engineering-focused tooling, such as chaos experimentation tooling, is extremely important. However, engineers that create these tools often overlook the value of UX, or don’t have the relevant skills in user design research to undertake this. - We all work in socio-technical systems. It is important to take the time to understand both aspects. Developing empathy and working alongside teams that you are trying to influence is essential. It is extremely important to continually work to build correct “mental models” of a system. - The before and after of running a chaos experiment is as important as running the experiment itself. However, the aspects of planning, creating effective hypotheses, and analysing and disseminating the results are often under-resourced. - Incident analysis can be a catalyst to help you understand more about your system. The Learning from Incidents website, alongside books such as Sidney Dekker’s The Field Guide to Understanding Human Error and Scott Snook’s Friendly Fire, can provide excellent background information to these topics.

Rob Skillington on Metrics Collection, Uber’s M3, and OpenMetrics Jun 26, 2020

Show notes

In this podcast, Rob Skillington, co-founder and CTO at Chronosphere, sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: metrics collection at scale, multi-dimensional metrics and high-cardinality, developer experience with platform tooling, and open standards related to observability. Why listen to this podcast: - Over the past ten years the requirements related to monitoring and alerting, and the approach taken to implement this, has changed considerably. Compute is now ephemeral and dynamic, services are more numerous, and engineers want to instrument more things. Scalability of a monitoring solution is vitally important. - One of the challenges with metric data is the limited information for providing context for collected values. This can be solved by using multi-dimensional metrics. Dimensions of a metric are name-value pairs that carry additional data to describe the metric value. High dimensionality can lead to high cardinality. - Uber’s M3 metrics collection system initially used open source components such as Cassandra and ElasticSearch for storage and indexing. As the scale of usage of M3 increased, these OSS components were gradually replaced by custom components, such as M3DB. - Building an effective user experience for operational tooling, especially observability-foused tooling, is vitally important. Engineers will be interacting with these tools on a daily basis. They will also be relying on these tools for both alerting and being able to locate and understand what is occurring during production issues. - Open standards are vitally important for interoperability. The OpenMetrics project is an effort to create an open standard for transmitting metrics at scale, with support for both text representation and protocol buffers.

Johnny Boursiquot on Serverless Go and Site Reliability Engineering at Heroku Jun 19, 2020

Show notes

In this podcast, Johnny Boursiquot, Site Reliability Engineer at Heroku, sat down with InfoQ podcast co-host Daniel Bryant and discussed topics that included: why Go is a useful language for building Function-as-a-Service (FaaS) style applications; how Heroku implement the role of Site Reliability Engineer (SRE); and why the ability to teach is such a valuable skill. Why listen to this podcast: - Go is a useful language for building Function-as-a-Service (FaaS) style applications. The ability to build Go applications into a static binary reduces the need for dependency management, and the quick runtime and application start time is good for initiation and scaling - The FaaS development toolchain has improved over the years. Many cloud providers now provide local runtimes, e.g. AWS SAM Local, and service simulators, e.g. LocalStack. Testing in production is facilitated by the ability to do dark launches and canary releasing at the ingress/API gateway - Developing “serverless” applications typically does not remove the need for operational expertise on a development team. Designing systems appropriately and getting the most out of the runtime (with minimal cost) requires knowledge of the underlying infrastructure components - The role of Site Reliability Engineering (SRE) looks different across practically every organisation. The Heroku SRE team have adapted well-established patterns and practices into their roles. They act as “diplomats”, working closely with product teams to share knowledge around operational best practices - The ability to teach is a valuable skill, regardless of your job. Teaching people to code or to embrace important operational principles is extremely rewarding. - Engineers who teach must seek to escape the pull of their ego; by focusing on the needs of the people you are teaching, much more progress can be made.
