Who is this presentation for?

  • Software architects, developers, operators who want to migrate and learn about complexity and solutions when integrating and securing multiple, distinctly different environments, and for anyone who has already migrated and is experiencing these difficulties




The popularity and usage of schedulers such as Kubernetes are growing; recent statistics show that 40% of organizations use Kubernetes. However, many organizations are also reliant on large numbers of virtual machines or bare metal servers to run their applications.

Organizations wanting to modernize brownfield environments and transition to modern schedulers need a way to connect and secure these existing applications. Applications running in virtual machines have the same requirements for security, reliability, and observability as modern scheduler-based applications. Managing network security for these applications is complex, risk averse, and slow. A fat-client approach to tackling these problems is difficult to implement, if not impossible, especially with off-the-shelf software. A service mesh is a dedicated network layer that can solve the aforementioned problems.

Erik Veld and Nic Jackson walk you through how to integrate applications running in virtual machines with highly dynamic, heterogeneous greenfield environments, while keeping it all secure. They also show you how you can apply the capabilities of a service mesh to applications running in virtual machines or on bare metal.

Prerequisite knowledge

  • Familiarity with schedulers and Kubernetes, modern application design practices, and cloud and virtualized environments

Materials or downloads needed in advance

  • A laptop with a modern browser (Firefox or Chrome) installed

What you'll learn

  • Learn how to maintain and secure networks between brownfield and greenfield applications, how to implement modern reliability and observability practices in legacy applications, and how a service mesh can simplify migration strategies
  • Discover available services
