Possible disadvantages of RHEV

• Cost
  Although RHEV is open-source, enterprise support and subscription costs can be high, which may be a concern for smaller businesses.
• Complexity
  Setting up and managing RHEV can be complex, requiring specialized knowledge and skills, which might contribute to higher administrative overhead.
• Hardware Compatibility
  RHEV requires specific hardware compatibility, which may not always align with the existing infrastructure of some organizations.
• Performance Overhead
  Like many virtualization solutions, RHEV can introduce performance overhead, which may affect the performance of hosted VMs compared to bare-metal solutions.
• Learning Curve
  New users might experience a steep learning curve as they acquaint themselves with the platform and its features.

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.
