Kubernetes has emerged as a central player in the realm of container orchestration and platform engineering. In a recent talk at GOTO Aarhus 2023, K8s expert and author of ‘Platform Engineering on Kubernetes’, Mauricio Salatino shared insights on the technical aspects of navigating the ever-evolving landscape of scalable and resilient software deployments. Learn about the challenges faced, solutions implemented, and the evolving role of platform engineering in the Cloud Native Computing Foundation (CNCF) space.
Watch the entire video for a nuanced exploration of Kubernetes, platform engineering, and the integration of Dapr, blending theoretical insights with practical examples.
The Pain Points of Kubernetes Adoption
Kubernetes adoption is often driven by the need to deliver software more frequently and efficiently to end-users. As a result, developers face a steep learning curve, especially in terms of containerizing applications for production use.
The question is: Should developers require to know about Kubernetes, or is it more of an operational concern?
Managing Multiple Kubernetes Clusters
Organizations using Kubernetes may find themselves dealing with multiple clusters, each serving different purposes. Managing these clusters involves considerations of provisioning, updates, and ownership by different teams. According to Mauricio, templating mechanisms become crucial, catering to the varying needs of production, staging, and developer clusters.
The Expanding Toolset in CNCF
The CNCF ecosystem offers a plethora of tools, each addressing specific challenges within the Kubernetes space. Organizations need dedicated teams to curate and choose tools that align with their unique requirements.
As organizations scale with multiple clusters, the question of how to allocate clusters to different users or teams becomes critical. Decisions about isolation levels and whether to have single or multiple clusters for development environments surface.
Costs and Cost Efficiency
Running Kubernetes can be expensive and organizations need to carefully consider the cost-effectiveness of their infrastructure. The region-based nature of clusters, coupled with cloud provider costs, requires a strategic approach to resource allocation.
Platform Engineering in CNCF
Platform engineering involves building efficient, cost-effective platforms that empower developers, data scientists, and operations teams.
The rise of platform engineering within CNCF addresses challenges through the creation of specialized teams. The platform engineering movement finds expression in tools like Crossplane. This open-source project extends Kubernetes, enabling platform engineers to automate infrastructure provisioning seamlessly across various cloud providers.
Experimentation and Advanced Traffic Management
GitOps and tools like Dapr facilitate faster development cycles by allowing developers to experiment with changes in isolated environments. Advanced traffic management tools, such as Flagger and KNative, enable sophisticated release strategies like canary releases and A/B testing.
(Dapr)ting from Complexity to Simplicity
Integrating Dapr into the Kubernetes ecosystem elevates its capabilities. Dapr provides a runtime to simplify the development of distributed applications, addressing challenges such as state management, service invocation, and event-driven architecture.
Mauricio encourages leveraging Dapr for state management, event-driven architecture, and seamless service invocation, creating a resilient and scalable foundation for distributed applications.
Dapr's polyglot capabilities enable developers to use multiple languages seamlessly. The runtime provides consistent behavior, whether developers are using Go, Java, or other languages, simplifying the creation of distributed applications.
Dapr – The Technical Tour de Force for Developers
Dapr addresses critical aspects such as resiliency, dynamic scaling, and traffic management. These features are typically associated with service meshes, and Dapr seamlessly integrates them into the Kubernetes environment, offering developers a robust foundation for building resilient systems.
Platform Capabilities for Application Developers
Platform capabilities refer to the services and functionalities provided to application developers by the platform team. Rather than exposing the intricacies of Kubernetes, platforms aim to offer a curated set of capabilities to enhance developer productivity.
The journey through Kubernetes adoption involves addressing challenges related to learning curves, multi-cluster management, tool selection, cost efficiency, and more. Platform engineering emerges as a strategic response, focusing on creating efficient platforms that empower development teams. As organizations navigate this landscape, the emphasis on experimentation, advanced traffic management, and thoughtful platform capabilities becomes crucial for success in the cloud-native era.
