Apache HTTP Server vs Undertow: What are the differences?
Introduction:
Apache HTTP Server and Undertow are both web servers that serve as the backbone for hosting websites. However, they differ in various aspects that cater to different needs and preferences.
1. Performance: Apache HTTP Server is known for its stability and reliability, making it a popular choice for traditional web applications. On the other hand, Undertow is focused on performance and scalability, making it a preferred option for modern, high-performance applications that require low-latency responses.
2. Memory Usage: Undertow has a smaller memory footprint compared to Apache HTTP Server, making it more suitable for resource-constrained environments or microservices where efficient memory usage is crucial.
3. Configuration: Apache HTTP Server has a complex configuration system with numerous directives and modules, allowing for a high level of customization. In contrast, Undertow has a simpler configuration setup, making it easier to set up and manage for beginners or projects with straightforward requirements.
4. Embedded Capabilities: Undertow is designed to be embedded within Java applications, providing seamless integration with Java frameworks and applications. Apache HTTP Server, on the other hand, is typically used as a standalone server and may require additional configurations for embedding.
5. Community Support: Apache HTTP Server has a large and active community with extensive documentation, plugins, and support resources available. Undertow, although gaining popularity, may have a smaller community and fewer resources in comparison.
6. Architecture: Apache HTTP Server uses a multi-process, multi-threaded architecture, which can handle a high volume of requests but may consume more resources. Undertow, with its non-blocking I/O architecture, is more efficient in handling concurrent connections and is better suited for handling modern web applications with high throughput requirements.
In Summary, Apache HTTP Server and Undertow differ in terms of performance, memory usage, configuration, embedded capabilities, community support, and architecture, catering to different needs in the realm of web hosting and application development.
