Amazon EKS features and specs

• Managed Service
  Amazon EKS is a managed Kubernetes service, which means AWS handles the control plane, saving time and operational overhead.
• Scalability
  EKS integrates with AWS's scaling tools such as Auto Scaling groups, allowing for seamless scaling of applications.
• Security
  Offers integration with AWS IAM for authentication and supports network policies and encryption for securing applications.
• AWS Ecosystem Integration
  Deeply integrated with other AWS services like VPC, IAM, CloudWatch, and more, providing a streamlined experience.
• Community and Ecosystem Support
  Being a Kubernetes service, it benefits from the extensive Kubernetes ecosystem and community support for tools and extensions.

Possible disadvantages of Amazon EKS

• Cost
  While EKS simplifies management, it comes with additional costs over using self-managed Kubernetes clusters.
• Complexity
  EKS, like Kubernetes itself, can be complex to manage and configure, needing skilled personnel to handle deployments.
• Vendor Lock-In
  Reliance on AWS services can make it hard to migrate to another cloud provider or an on-premises solution if needed.
• Steeper Learning Curve
  Organizations new to Kubernetes might find the learning curve steep when adopting EKS, requiring significant training and adjustment.
• Regional Availability
  EKS might not be available in all AWS regions, limiting deployment flexibility for global applications.

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.
