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.

Azure Application Gateway features and specs

• Scalability
  Azure Application Gateway can automatically scale up or down based on traffic demands, ensuring application availability and performance without manual intervention.
• Security Features
  It offers a Web Application Firewall (WAF) that helps protect your applications from common vulnerabilities and attacks, improving the overall security posture.
• SSL Termination
  By offloading SSL termination to the application gateway, it reduces the web server's computation load, allowing better resource allocation.
• URL-based Routing
  Supports URL-based routing which allows for more advanced traffic distribution strategies and optimization of backend resources.
• Multi-Region Redundancy
  Supports configurations for multi-region redundancy, allowing for improved resilience and availability across geographical locations.

Possible disadvantages of Azure Application Gateway

• Complexity
  Initial setup and configuration can be complex, especially for users who are not familiar with Azure services, potentially leading to increased deployment times.
• Cost
  Costs can increase significantly with higher traffic volumes and additional features like the Web Application Firewall, impacting the overall IT budget.
• Latency
  There might be additional latency introduced due to the routing and processing of requests through the gateway, which can affect application performance.
• Limited Customization
  Compared to some other solutions, Azure Application Gateway offers limited customization options for specific routing and traffic management scenarios.
• Dependency on Azure Region
  Performance and availability can be impacted by the Azure region where the application gateway is deployed, leading to potential issues if that region experiences problems.
