Azkaban features and specs

• Scalability
  Azkaban is designed to efficiently manage and schedule batch jobs, making it suitable for handling large-scale data processing tasks in a distributed environment.
• Dependency Management
  Azkaban offers robust dependency management, allowing complex job workflows with dependencies to be easily orchestrated and visualized.
• Web-Based Interface
  It provides a user-friendly web interface for managing workflows, monitoring job execution, and handling configurations, which enhances user interaction.
• Open Source
  As an open-source tool, Azkaban allows for customization and community contributions, which can lead to rapid feature enhancements and bug fixes.
• Integration
  Azkaban integrates well with other Hadoop ecosystem tools, making it an excellent choice for big data environments.

Possible disadvantages of Azkaban

• Complex Setup
  Setting up and configuring Azkaban can be complex and time-consuming, requiring detailed knowledge of its system and dependencies.
• Limited Support
  Being an open-source project, it might not have the extensive enterprise-level support that commercial workflow management tools offer.
• Resource Management
  Azkaban lacks advanced resource management capabilities found in some other orchestration tools, which can be a limitation in environments with diverse resource needs.
• Interface Limitations
  While it does provide a web-based interface, some users find it less intuitive compared to those of other modern workflow management systems.
• Feature Set
  Azkaban may lack some advanced features and integrations available in newer orchestration tools, which could be limiting for certain complex or evolving needs.

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.
