Talks on Wurreka:

Leading technical organizations in micro-service based architectures all use an orchestrator in their datacenter; be it Apache Mesos, Kubernetes, Tupperware, the Borg or Omega. The dominate platforms in the open source space are Kubernetes and Mesos. This session will dive deep into the core difference including:

  • Pod container lifecycle differences
  • In production scaling differences
  • Scheduling and orchestration management difference
  • Reconciliation management
  • Resource selection (affinity vs anti-affinity)
  • Service discovery
    • This is NOT a one is better than the other smack-down. There are pro/con consequences for each orchestrator.

      Presented by an engineer that has worked for over 6 years with Docker and container orchestrators. Attendees will leave with a clear understanding of the Kubernetes API, scheduler, controllers and operators, and how they are different than the Mesos 2-level scheduler. The session will include how resources are managed in the cluster along with pod life-cycle management. The session will call out topics of concern regarding availability and scalability and how to best manage those concerns.

The maturing of industry projects and tools around cloud development and administration has led to the formation of the Cloud Native Computing Foundation. This new foundation is similar to the Apache Foundation in that it provides governance over projects from incubation to maturity. These projects define the current and future standards of the cloud which is important for all devops teams to be aware of. This session is a guided at jet speed tour of each project and how it fits in the eco-system.

This session will briefly cover each of the CNCF projects will a outline of:

  • what the project is
  • how it works
  • level of maturity
  • competitive landscape

The projects covered include:

  • Kubernetes
  • containerd
  • Prometheus
  • OpenTracing
  • Fluentd
  • rkt
  • CNI
  • Jaeger
  • Notary
  • Envoy
  • CoreDNS
  • Linkerd

So your server is having issues? memory? Connections? Limited response? Is the first solution to bounce the server? Perhaps change some VM flags or add some logging? In todays Java 9 world, with its superior runtime monitoring and management capabilities the reasons to the bounce the server have been greatly reduced.

This session will look at the Java monitoring and management capabilities, which includes the ability to make VM argument changes on the fly. This session will dive into the different memory compartments and how they are used by the JVM. Final this session will explore the different GC options and how they affect response times and throughput.

This session will include new features in Java 9 to make it more container aware.

Containers and Micro-service are like peanut butter and jelly, they just go together. However do you know how resources are managed in a container and how that affects your application. This session will dive into how Java is affected living under control groups.

This session will review containers, the underlying technology to containers along with different container runtimes such as Docker. We will look at the anatomy of a container including control groups (cgroups) and namespaces. This session will conclude with the challenges of running the JRE in a container and the impact that has on the efficiency of the process at scale.

This session will include container friendly changes to Java 9 around memory and ergonomics. It will also provide advice on how to get consistent CPU share.

We build development teams based on individual ability to write code but development of a software project of any significance is beyond a single persons effort with a very particular set of skills. It requires a team of members with a number array of skills. It requires social skills. It requires tools and alignment. It requires shared contextual models.

This session will distill a couple decades of software consulting lessons learn in software engineering along with Ugandan fun to uncover the true way to developing more with less.
