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.

ZoneMinder features and specs

• Open Source
  ZoneMinder is an open-source application, meaning its source code is freely available to the public. Users can inspect, modify, and enhance the code to suit their specific needs without incurring licensing fees.
• Cost-effective
  Since it is open-source, ZoneMinder can be used for free. This makes it an attractive option for small businesses and home users looking for a cost-effective surveillance solution.
• Highly Customizable
  Users can customize ZoneMinder through extensive configuration options and a modular design. It supports a wide range of camera types and input sources, allowing for flexible deployment.
• Community Support
  A large user community contributes to forums, documentation, and third-party plugins, providing a robust support network for new users.
• Feature-Rich
  ZoneMinder includes a wide range of features, such as motion detection, event recording, alerts, and remote access, making it a powerful surveillance solution.

Possible disadvantages of ZoneMinder

• Complex Setup
  The installation and configuration of ZoneMinder can be complex and time-consuming, especially for users who are not familiar with Linux and server administration.
• Resource Intensive
  ZoneMinder can be resource-intensive, requiring significant CPU and memory to handle multiple camera feeds and high-resolution footage.
• User Interface
  The user interface is considered outdated and not very intuitive, which can present a steep learning curve for new users.
• Limited Vendor Support
  Unlike commercial solutions, ZoneMinder lacks official vendor support. Users must rely on community forums and documentation for troubleshooting and assistance.
• Security Concerns
  As an open-source project, the onus is on users to ensure that their installation is secure. This can be challenging for users without a solid understanding of network and system security.
