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.

Dokku features and specs

• Ease of Use
  Dokku provides simple commands and clear documentation, making it straightforward to deploy, manage, and scale applications using a process similar to Heroku.
• Heroku Compatibility
  Dokku uses a Heroku-like buildpack system, which allows users to deploy applications with ease if they are already familiar with Heroku.
• Cost-Effective
  Being an open-source project, Dokku itself is free to use, which can significantly reduce the cost of deploying applications compared to using premium services.
• Customizability
  As an open-source tool, Dokku allows for extensive customization according to user needs, offering flexibility in deployment settings and configurations.
• Plugin System
  Dokku supports a wide range of plugins, enabling users to extend its functionality easily, such as adding database support, monitoring capabilities, and more.

Possible disadvantages of Dokku

• Initial Setup Complexity
  Setting up Dokku for the first time might be challenging, especially for users with limited experience in server management and Linux administration.
• Limited Built-In Features
  Compared to fully-managed PaaS solutions, Dokku has fewer built-in features, potentially requiring more effort to implement certain functionalities such as load balancing and extensive monitoring.
• Scalability Challenges
  While Dokku supports basic scaling, it might not handle extensive scaling needs as efficiently as more robust enterprise-level solutions.
• Resource Management
  Dokku's resource management capabilities are limited compared to dedicated orchestration tools like Kubernetes, making it less suitable for complex and large-scale application deployments.
• Community Support
  Even though Dokku has a growing community, it is not as large or as active as some of the more popular platforms, which can limit the availability of community-driven support and resources.
