Cloud-native applications are designed to draw upon the performance, scalability, and reliability benefits of distributed systems. Unfortunately, distributed systems often come at the cost of added complexity. As individual components of your application are distributed across networks, and those networks have communication gaps or experience degraded performance, your distributed application components need to continue to function independently.

To avoid inconsistencies in application state, distributed systems should be designed with an understanding that components will fail. Nowhere is this more prominent than in the network. Consequently, at their core, distributed systems rely heavily on load balancing—the distribution of requests across two or more systems—in order to be resilient in the face of network disruption and horizontally scale as system load fluctuates.

Microservices present challenges of coordination, SSL termination and socket connection among others. Looking to different cloud providers to assist with their load-balancers leaves you wanting as features socket connection support, SSL termination and geo-distributed load-balancing are often absent.

Navigating the container ecosystem can be confusing. Deciding where to dip your toes is challenging for those stepping into container and microservices waters. Even those who have already ventured knee-deep still wade through many questions as they progress in their cloud native journey. To help them guide them through the ecosystem, the Cloud Native Computing Foundation (CNCF) recently launched a Cloud Native Ambassadors program at its inaugural CloudNativeDay in Toronto.

Recognized for their expertise, Cloud Native Ambassadors are individuals who belong to a CNCF member organization and are selected based on their passion for cloud native technology and willingness to help others learn. Most ambassadors also organize or are involved in community meetups oriented toward technologies and projects governed by the CNCF. Forty-one meetups worldwide have joined the program to date (disclaimer: I’m a CNCF Ambassador  and an organizer of the Microservices and Containers Austin meetup in Austin, TX.). Continue reading »
