Prometheus features and specs

• Powerful Query Language
  Prometheus uses PromQL, a flexible and powerful query language that allows for complex and detailed queries.
• Dimensional Data Model
  Prometheus employs a multidimensional data model with time series data identified by metric name and key-value pairs, offering great flexibility in data organization.
• Auto-Discovery
  It supports service discovery mechanisms to automatically locate and scrape metrics from jobs, simplifying the monitoring process.
• Alerting
  Prometheus includes built-in alerting capabilities that allow you to trigger alerts based on PromQL queries, which can be integrated with different alert management systems.
• Scalability
  Its architecture, which uses independent single servers, scales well, allowing you to handle a large number of time series efficiently.
• Open Source
  Prometheus is open-source and supported by a large community, offering transparency, regular updates, and numerous integrations.
• Easy Integration
  Thanks to its compatibility with various data exporting standards and a myriad of existing exporters, integrating Prometheus into existing systems is streamlined.

Possible disadvantages of Prometheus

• Single Points of Failure
  Prometheus instances operate independently, meaning that if a server goes down, the metrics it monitored will be unavailable unless replicated manually.
• Storage Overhead
  Prometheus can consume significant storage, especially for high-resolution time series data, which might necessitate careful planning and management.
• Limited Long-Term Storage
  By default, Prometheus is not designed for long-term storage of metrics and may require integration with other systems like Thanos or Cortex for this purpose.
• Complexity for Beginners
  The sheer number of features and the complexities associated with PromQL can present a steep learning curve for newcomers.
• Scaling Write Operations
  In high-scale environments, write operations might become a bottleneck due to the single-server nature of the Prometheus architecture.
• Lack of Native High Availability
  While Prometheus supports running multiple instances, it does not provide built-in high availability features out-of-the-box, necessitating additional configurations.
• No Built-in Authentication and Authorization
  Prometheus lacks native support for secure authentication and authorization, which means these features must be externally managed.

CodeIgniter features and specs

• Performance
  CodeIgniter is known for its exceptional performance and fast execution, which is beneficial for applications requiring quick load times.
• Documentation
  CodeIgniter offers comprehensive and clear documentation, making it easier for developers to understand and use the framework effectively.
• Easy to Learn
  CodeIgniter's simple and straightforward syntax makes it relatively easy for beginners to learn and start developing applications quickly.
• Lightweight
  The framework is lightweight and does not impose many dependencies or require a specific server environment, providing flexibility to developers.
• Community Support
  CodeIgniter has a strong and active community, which means plenty of resources, forums, and add-ons are available for developers.
• Built-in Security Features
  CodeIgniter comes with built-in security features like XSS filtering and CSRF protection, helping developers to secure their applications with minimal effort.
• MVC Architecture
  The framework follows the Model-View-Controller (MVC) architecture, promoting clean code separation and better organization of the project.

Possible disadvantages of CodeIgniter

• Lack of Modern Features
  CodeIgniter does not include many modern features found in other frameworks, such as built-in ORM or out-of-the-box RESTful API support.
• Limited Modular Extensions
  It has fewer modular extensions compared to other frameworks like Laravel or Symfony, which can limit code reusability and scalability.
• Manual Routing
  Routing in CodeIgniter is somewhat manual and less intuitive compared to other frameworks that offer more automatic and flexible routing mechanisms.
• Outdated PHP Practices
  Some of the practices and conventions in CodeIgniter are considered outdated with respect to modern PHP development trends.
• No Built-in Authentication
  CodeIgniter does not come with a built-in authentication system, requiring developers to implement their own or use third-party libraries.
• Less Emphasis on Testing
  CodeIgniter has less built-in support and emphasis on unit testing compared to other frameworks like Laravel, making it harder to implement TDD or BDD.
• Lack of Native Composer Support
  The framework's native support for Composer, PHP's dependency manager, is not as robust as other modern frameworks, which can complicate dependency management.
