Deis features and specs

• Ease of Use
  Deis offers a simple and intuitive interface for managing applications, making it accessible for developers to deploy and scale applications easily.
• Scalability
  As a PaaS built on Kubernetes, Deis allows applications to scale with ease, leveraging Kubernetes' powerful orchestration tools.
• Extensibility
  Deis is highly customizable and can be extended with additional functionalities, fitting a wide range of use cases and allowing integration with existing workflows.
• Open Source
  Being an open-source platform, Deis fosters community collaboration and offers transparency, allowing developers to customize and contribute to its development.
• Microservices Support
  Provides strong support for microservices architecture, enabling efficient deployment and management of containerized applications.

Possible disadvantages of Deis

• Maintenance
  As with any platform that requires self-hosting, maintaining and updating the Deis platform demands resources and expertise.
• Complexity
  For teams not familiar with Kubernetes, there can be a steep learning curve associated with using Deis, impacting productivity initially.
• Deprecation
  As Deis transitioned into being part of Microsoft Azure's offerings, the original Deis project is no longer actively maintained, requiring users to migrate to alternatives.
• Limited Documentation
  Compared to more established and currently maintained PaaS solutions, Deis might have less comprehensive and outdated documentation.
• Community Support
  With its deprecation, the community around Deis has diminished, leading to reduced availability of community support and resources.

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.
