Possible disadvantages of Kami App

  • Limited Free Version
    The free version of Kami has limited functionalities compared to the paid version, potentially requiring users to purchase a subscription for full access.
  • Occasional Sync Issues
    There are reports of occasional synchronization issues when working on documents collaboratively, which can result in lost work or conflicting document versions.
  • Performance Lag
    Users have noted that the application can sometimes be slow, especially with larger documents, affecting the overall user experience.
  • Steep Learning Curve
    The wide range of features and tools can initially be overwhelming for new users, requiring a learning period to become proficient.
  • Dependence on Chrome Extension
    Full functionality is better experienced through the Chrome extension, which may not be ideal for users who prefer other browsers or platforms.

Selenium in AWS Lambda features and specs

  • Scalability
    AWS Lambda automatically scales your Selenium tests by running multiple instances simultaneously, allowing for efficient parallel testing without managing servers.
  • Cost-effectiveness
    With AWS Lambda, you only pay for the compute time that you consume, which can significantly reduce costs compared to traditional server-based deployments, especially for occasional testing.
  • Maintenance-free
    AWS Lambda abstracts away server maintenance, updates, and patch management, allowing you to focus exclusively on writing and executing Selenium tests.
  • Integration with AWS Services
    AWS Lambda integrates seamlessly with other AWS services such as S3, DynamoDB, and API Gateway, enabling you to build comprehensive, cloud-native testing workflows.

Possible disadvantages of Selenium in AWS Lambda

  • Execution Time Limitations
    AWS Lambda imposes a maximum execution time limit (15 minutes as of 2023), which may not be sufficient for running extensive Selenium test suites.
  • Cold Start Latency
    When Lambda functions are not frequently invoked, they can experience latency during cold starts, potentially affecting the performance of Selenium tests.
  • Browser Environment Setup
    Running Selenium in AWS Lambda requires setting up browser binaries in a serverless environment, which can be complex and may require custom Lambda layers or container images.
  • Resource Limitations
    Lambda functions have restricted memory and computing capabilities, which might limit the execution of resource-intensive Selenium tests.
