AWS Lambda features and specs

• Scalability
  AWS Lambda automatically scales your application by running your code in response to each trigger. This means no manual intervention is required to handle varying levels of traffic.
• Cost-effectiveness
  You only pay for the compute time you consume. Billing is metered in increments of 100 milliseconds and you are not charged when your code is not running.
• Reduced Operations Overhead
  AWS Lambda abstracts the infrastructure management layer, so there is no need to manage or provision servers. This allows you to focus more on writing code for your applications.
• Flexibility
  Supports multiple programming languages such as Python, Node.js, Ruby, Java, Go, and .NET, which allows you to use the language you are most comfortable with.
• Integration with Other AWS Services
  Seamlessly integrates with many other AWS services such as S3, DynamoDB, RDS, SNS, and more, making it versatile and highly functional.
• Automatic Scaling and Load Balancing
  Handles thousands of concurrent requests without managing the scaling yourself, making it suitable for applications requiring high availability and reliability.

Possible disadvantages of AWS Lambda

• Cold Start Latency
  The first request to a Lambda function after it has been idle for a certain period can take longer to execute. This is referred to as a 'cold start' and can impact performance.
• Resource Limits
  Lambda has defined limits, such as a maximum execution timeout of 15 minutes, memory allocation ranging from 128 MB to 10,240 MB, and temporary storage up to 512 MB.
• Vendor Lock-in
  Using AWS Lambda ties you into the AWS ecosystem, making it difficult to migrate to another cloud provider or an on-premises solution without significant modifications to your application.
• Complexity of Debugging
  Debugging and monitoring distributed, serverless applications can be more complex compared to traditional applications due to the lack of direct access to the underlying infrastructure.
• Cold Start Issues with VPC
  When Lambda functions are configured to access resources within a Virtual Private Cloud (VPC), the cold start latency can be exacerbated due to additional VPC networking overhead.
• Limited Execution Control
  AWS Lambda is designed for stateless, short-running tasks and may not be suitable for long-running processes or tasks requiring complex orchestration.

Sentora features and specs

• Open Source
  Sentora is an open-source hosting control panel, which means it's free to use and you can modify it according to your needs.
• User-friendly Interface
  It has a straightforward and easy-to-navigate interface, making it simple for users of all levels to manage their hosting accounts.

  Allows extending functionality with modules, meaning you can add new features as needed.
• Community Support
  A supportive community forums help users troubleshoot and enhance their Sentora experience.
• Linux Environment
  Specifically designed for Linux, it greatly integrates with this environment, offering optimal performance.

Possible disadvantages of Sentora

• Limited to Linux
  Sentora does not support Windows servers, which limits its usability for those needing a Windows-based solution.
• Outdated Technology
  Some users have reported that Sentora can feel outdated compared to newer control panels with more modern features.
• Limited Scalability
  Not as scalable or robust as some other more enterprise-focused solutions.
• Security Concerns
  Being less popular than some competitors, it may receive fewer security updates and patches.
• Manual Updates
  Users have to manually keep the software updated, which might be cumbersome for those wanting an auto-update feature.
