Meshing Around with Service Traffic
Kubernetes out of the box is a strong platform for running and coordinating large collections of services, containers, and applications. As is, Kubernetes is powerful for many solutions.
Remember Underdog? He was a mild-mannered dog, but when stress and conflict were introduced to the plot he took a magic pill, he became a superhero. Istio is a superhero for Kubernetes.
Istio is an open, platform-independent service mesh that manages communications between services in a transparent way. With a distributed architecture many things can fail, slow down and become less secure. Istio provides solutions to those stresses in our plot toward this architecture style:
• Traffic management
• Observability
• Policy enforcement
• Service identity and security
We will explore these benefits with Istio through some working examples on Kubernetes. The key point is this meshing solution allows your Java code to be less coupled to the inherent weaknesses of a distributed platform.
About Jonathan Johnson
Jonathan Johnson is an independent software architect with a concentration on helping others unpack the riches in the cloud native and Kubernetes ecosystems.
For 30 years Jonathan has been designing useful software to move businesses forward. His career began creating laboratory instrument software and throughout the years, his focus has been moving with industry advances benefitting from Moore’s Law. He was enticed by the advent of object-oriented design and applied it to financial software. As banking moved to the internet, enterprise applications took off and Java exploded onto the scene. Since then, he has inhabited that ecosystem. After a few years, he returned to laboratory software and leveraged Java-based state machines and enterprise services to manage the terabytes of data flowing out of DNA sequencing instruments. As a hands-on architect, he applied the advantages of microservices, containers, and Kubernetes with a laboratory management platform.
Today he enjoys sharing his experience with peers. He provides perspective on ways to modernize application architectures while adhering to the fundamentals of modularity - high cohesion and low coupling.microservices, containers, and Kubernetes to their laboratory management platform.
