Apache Tomcat features and specs

• Open Source
  Apache Tomcat is an open-source software, which means it is freely available for use and modifications. This can significantly reduce the cost of ownership and allows for customization.
• Community Support
  Being a widely-used open-source server, Tomcat has a large and active community of developers and users who contribute to its documentation, plugins, and forums, providing extensive support.
• Lightweight
  Tomcat is designed to be a lightweight servlet container, making it faster and less resource-intensive compared to full-blown Java EE application servers.
• Integration with Popular Frameworks
  Tomcat integrates well with popular Java frameworks such as Spring and Hibernate, making it easier for developers to deploy and manage web applications.
• Easy to Set Up and Configure
  Tomcat is relatively easy to set up and configure, making it suitable for both development and production environments.
• Frequent Updates
  Regular updates and patches are released to improve performance, security, and compatibility, ensuring the server is up-to-date with the latest web technologies.

Possible disadvantages of Apache Tomcat

• Limited Functionality
  While Tomcat is a powerful servlet container, it lacks some of the advanced features found in full-fledged Java EE application servers, which might be necessary for complex enterprise applications.
• Resource Management
  Tomcat's default configuration might not be suitable for high traffic web applications, requiring significant tweaking and tuning to handle heavy loads effectively.
• Documentation Quality
  The documentation, while extensive, can sometimes be hard to navigate and understand, especially for beginners. This can slow down the learning curve.
• Limited Built-in Tools
  Compared to other full-stack application servers, Tomcat comes with limited built-in tooling for monitoring, load balancing, and clustering, often requiring third-party solutions.
• Security Concerns
  As with any open-source project, security vulnerabilities may emerge. It requires constant monitoring and timely updates to ensure security.
• Lack of EJB Support
  Tomcat does not support Enterprise JavaBeans (EJB), limiting its use in scenarios where EJB is a crucial component of the architecture.

KrakenD features and specs

• High Performance
  KrakenD is designed to be very performant with low latency and high throughput, which makes it suitable for high-demand API Gateway requirements.
• Ease of Configuration
  KrakenD uses a declarative configuration, making it more straightforward to set up and manage without requiring complex coding.
• Scalability
  The framework supports horizontal scaling, enabling it to handle increased loads by distributing requests across multiple instances.
• Modular and Extensible
  Allows developers to implement custom plugins and modify the behavior of the gateway to fit specific business needs.
• Open-source Version
  KrakenD offers a community edition that is open source, providing access to a free version for those who want to explore its capabilities.

Possible disadvantages of KrakenD

• Learning Curve
  While powerful, KrakenD can have a steep learning curve for new adopters, primarily due to its extensive configuration options.
• Limited Built-in Middleware
  Compared to other API gateways, KrakenD may have fewer built-in middleware options, necessitating custom development for advanced functionality.
• Community Support
  Although there is an open-source version, the community support might not be as extensive as other more established or commercially supported platforms.
• Monitoring and Metrics
  Out-of-the-box monitoring capabilities may require additional setup or integration with other tools to provide comprehensive insights.
• Documentation
  Some users may find the documentation lacking in depth or examples, making it challenging to fully utilize all features.
