Google Persistent Disk features and specs

• High Durability
  Google Persistent Disk offers reliable storage with redundancy across multiple disks, ensuring data durability and reducing the risk of data loss.
• Automatic Backups
  Supports automated snapshots for easy backup and recovery, allowing you to restore data to any point in time.
• Scalability
  Easily scalable to accommodate growing storage needs. You can increase your storage capacity without downtime.
• Integration with Google Cloud
  Seamlessly integrates with other Google Cloud services for efficient management and utilization within the cloud ecosystem.
• Performance
  Provides persistent, high-performance block storage suitable for a wide range of applications, including databases and high-traffic websites.

Possible disadvantages of Google Persistent Disk

• Cost
  Pricing can become expensive, especially with large data sets or high IOPS requirements, compared to some other storage options.
• Zonal Availability
  Dependent on the geographical location of the data center and may require particular configurations for applications needing multi-region failover support.
• Complexity
  Managing and configuring persistent disks might be complex for users unfamiliar with Google Cloud's interface and services.
• Performance Limits
  Though performance is generally high, it may have limitations, such as maximum IOPS and throughput, depending on the disk type and size.

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.
