  • 11.20 Break
  • 11.40 Reverse Proxies, Load-Balancing & Clustering - Part 1
    Mark Thomas (markt)
    Apache Tomcat provides many options for expanding a Tomcat installation beyond a single instance. In this pair of presentations, Mark will review the options for load-balancing requests across multiple instances and for replicating session data between those instances. The pros and cons of each of the options will be discussed to enable attendees to make the right choices for their environment. The presentations will also cover common misconceptions and configuration mistakes to enable attendees to avoid those pitfalls.
  • 12.40 Lunch
  • 13.40 Reverse Proxies, Load-Balancing & Clustering - Part 2

  • 14.40 Tomcat from the Cluster to the Cloud
    Jean-Frederic Clere (jfclere)
    Using Tomcat in the cloud like in a cluster requires some work. The presentation will look to the problems and solutions to have a distributed application running in the cloud. A small cloud of Raspberry PI will be used to demo one solution using Kubernetes.
  • 15.40 Break
  • 16.00 Ask Us Anything
    Mark Thomas (markt), Rémy Maucherat (remm) and Jean-Frederic Clere (jfclere)

See you there!
