Architecture as Code: Kubernetes

The final installment of the Architecture as Code series delves into Kubernetes deployment patterns, exploring the nuances between single large clusters and multiple small clusters, each offering distinct advantages and challenges concerning resource efficiency, cost, multi-tenancy, and isolation. It highlights the flexibility of Kubernetes in supporting various deployment models and discusses multi-cloud strategies for maintaining high availability by distributing applications across different cloud service providers. The article illustrates the use of Pulumi, a tool that facilitates infrastructure as code by enabling reusable infrastructure components and supporting Kubernetes deployments on platforms like AWS, Azure, and Google Cloud. Additionally, it emphasizes the importance of architecture as code in embodying DevOps principles, promoting consistency, security, compliance, and cost management in modern application deployments.
