The service mesh approach was conceived to simplify and streamline the development and deployment of microservices-based applications. Replacing monolithic architectures, microservices is an approach—rather than a technology—to developing applications and services, enabling increased agility, flexibility, and scalability. Instead of creating an application as a single, inseparable entity comprising a client-side user interface, a server side-application, and a database, the microservices approach splits up the required functionality into a smaller, loosely coupled collection of independently deployable services.

The microservices architecture introduced a level of complexity that is exacerbated in cloud-native deployments. It requires that developers code and test every service-to-service and service-to-database connection to ensure the optimal performance, reliability, and security of the application’s runtime behavior. However, managing communications becomes increasingly complex in a cloud-native environment where an application can consist of hundreds of services and thousands of instances constantly changing state through dynamic orchestration. Moreover, developers must repeat these resource-intensive and time-consuming tasks for every application.

Addressing these challenges, a service mesh provides a consistent way of seamlessly coordinating a distributed mesh of microservices. Decoupling the application logic from the network communication logic, a service mesh offloads authentication, authorization, encryption, load balancing, rate limiting, service discovery, and logging and tracing from each application. This abstracts those functions as a programmable infrastructure layer running adjacent to each microservice. As a result, deploying a service mesh becomes more valuable as applications scale, providing the “plumbing” for cloud-native applications.

A service mesh:

  • Delivers out-of-the-box observability, resilience, routing, scalability, and security
  • Allows developers to focus on enhancing business value instead of recreating service connections
  • Eliminates the need for language-specific SDKs and tools to manage intra-service communications

Despite being a relatively new technology, more and more organizations are adopting open-source or vendor-provided service mesh solutions. This GigaOm Key Criteria report outlines critical criteria and evaluation metrics for selecting a service mesh. The corresponding GigaOm Radar Report provides an overview of notable service mesh vendors and their offerings available today. Together, these reports are designed to help educate decision-makers, providing critical insights for cloud-native application development…

Mike McNamara, tw telecom

Together we conquered many challenges, won impossible battles in the vendor industry and created a unique security practice. He has an interesting set of talents of being an engineer, innovator, and a thought leader, but never mixes any of these roles. That is what makes him successful as a leader. “Never be comfortable” is what Chris would tell me, which is what pushed me to do my first tech talk. I now have dozens behind me within some of the largest conferences known in the security vendor industry. Chris is nothing short of supernatural.

Leo Cruz, Myriad360

He would always be available as a sounding board for complex issues and provided me with amazing insight on long term planning and ways to scale up teams and business processes.
