Developers are faced with choosing between serverless computing and microservices architecture when designing modern applications, each offering distinct advantages in scalability, flexibility, and cost-efficiency. Serverless architecture, exemplified by AWS Lambda and Azure Functions, allows developers to focus purely on coding by automatically managing the infrastructure, providing benefits like event-driven execution, automatic scaling, and a pay-as-you-go pricing model. However, serverless may not suit long-running processes or applications requiring low-latency responses and fine-grained infrastructure control. Conversely, microservices architecture organizes an application into independently deployable units that communicate via APIs, offering advantages in resilience, technology flexibility, and scalability but requiring more operational management and orchestration via tools like Kubernetes. As both architectures gain popularity for their agility, many organizations adopt a hybrid model to leverage the strengths of each. DevZero emerges as a solution to address common challenges like over-provisioning by providing a Kubernetes-native platform that dynamically adjusts resources, improving cost efficiency and maintainability in both serverless and microservices environments.
