The way businesses build and run software has changed drastically over the last decade. From startups to enterprises, modern teams are moving away from traditional monolithic architectures and embracing more scalable, flexible solutions. Two of the most prominent approaches are serverless applications and containerized applications. Both have transformed the way applications are deployed, scaled, and maintained. In this blog, we’ll explore the best serverless platforms and container orchestration tools available in 2025, and help you decide which approach is right for your business.
What Are Serverless Applications?
Serverless applications are those applications on server where developer only focuses on writing code and cloud providers eg. AWS lambda handle server management, scaling, and maintenance, allowing teams to focus purely on code and functionality. The term "serverless" is a misnomer. There are still physical servers running the code; developers just don't have to manage them. Serverless applications are typically composed of many very small, isolated, single-purpose functions. This is one of the core principles of serverless architecture, often referred to as Function-as-a-Service (FaaS).
- Key Benefits: Auto-scaling, pay-as-you-go pricing, reduced DevOps overhead.
- Use Cases: Event-driven apps, APIs, real-time notifications, automation workflows.
What Are Containerized Applications?
Containerized applications package code and dependencies into portable, isolated environments. Containers ensure consistency across development, testing, and production, making them highly reliable for complex, distributed systems. Unlike Virtual Machines (VMs) which require a full, separate operating system for each application, containers share the host's operating system kernel. This makes them extremely lightweight, with startup times often measured in milliseconds, and allows many more containers to run on a single machine compared to VMs.
- Key Benefits: Portability, environment consistency, microservices-ready.
- Use Cases: SaaS platforms, enterprise-grade apps, hybrid and multi-cloud deployments.
