AWS Lambda VS Sejda

• 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

• 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.

• User-Friendly Interface
  Sejda features an intuitive and easy-to-navigate interface, making it accessible for users with varying levels of tech-savviness.
• Wide Range of PDF Tools
  Sejda offers a comprehensive set of tools for editing, merging, splitting, compressing, and converting PDFs, catering to diverse user needs.
• Cloud Integration
  Sejda allows users to import and export files directly from popular cloud storage services like Google Drive, Dropbox, and OneDrive, enhancing workflow efficiency.
• Security Features
  The platform provides options for adding passwords and encryption to PDFs, ensuring that sensitive information remains secure.
• Free Usage Tier
  Sejda offers a free version that allows users to perform basic PDF tasks without any cost, making it accessible to budget-conscious individuals and small businesses.

Possible disadvantages

• Limited Free Version
  The free plan comes with limitations such as a cap on the number of tasks performed per day and restrictions on the size of files that can be processed, which may not be sufficient for heavy users.
• Subscription Cost
  The premium plans, while offering more features, can be relatively costly, which might be a concern for individual users or small businesses.
• Internet Dependency
  As an online tool, Sejda requires a stable internet connection for optimal performance, which might be a limitation in areas with poor connectivity.
• Limited Advanced Features
  While Sejda covers a wide range of basic to intermediate PDF functionalities, it may lack some advanced features that professional users might require, such as advanced form filling and data extraction.
• Performance on Large Files
  Users may experience slower performance or occasional glitches when working with very large files, which could disrupt the user experience during critical tasks.
