Which serverless solution is the best for data governance?

AWS Lambda is probably the most mature serverless platform available today due to the amount of time it has been operating. It has proven to be reliable and is capable of handling workloads of various sizes.

AWS Lambda offers features beyond the basics that can be expected from every serverless provider. The service has become more flexible and powerful as time passes, allowing it to remain competitive and fresh.

Here are some of the features it boasts:

• Arbitrary executables: You can configure the Lambda service to run arbitrary executables to process events rather than working with language-specific functions.


• Custom runtimes: Users can implement their own language runtimes beyond those provided natively by Amazon.


• Provisioned concurrency: The ability to keep event handlers spun up and on standby to help mitigate the cold start problem of allocating resources at the time of the event.


• Easy access to persistence: Users can use Amazon's RDS Proxy  to connect to database instances securely from their functions and use Elastic File System to store file-based data. AWS Lambda charges based on resource usage tracked at the millisecond level. Unfortunately, the total cost of running AWS Lambda is often difficult to calculate up front because so many different factors affect the overall price.
  The total price is based on a number of factors:
  
  
  
  • The architecture executing the functions: x86 or Arm. This is charged based on the number of requests and the duration of each request.
  
  
  • The amount of memory allocated to the function: From 128 MB to 10,240 MB, allocated in 1 MB increments
  
  
  • Provisioned concurrency usage: If you choose to provision concurrency to help with performance, the extra concurrency will cost more
  
  
  • Amount of data transferred in and out of the functions
  
  
  • Lambda@ Edge usage: If you deploy your functions closer to clients, you will be charged for that extra service. AWS Lambda is a robust, mature platform for building serverless applications. It has the benefit of experience over many other providers and still leads the way in many features and evolutions in the serverless space.
  
  
  • Its integration with other AWS services makes it an obvious choice for those already living in Amazon's ecosystem. Unfortunately, it also inherits the cost prediction difficulties that AWS services are often criticized for.
    Overall, however, AWS Lambda is a strong, general choice for serverless functions. It is likely to continue its trajectory of adding features and integrations to remain competitive.
