AWS Lambda vs. Retool

Lambda excels at event-driven, short-lived tasks, such as processing files or building simple APIs. However, it's less ideal for long-running, computationally intensive, or applications that rely on carrying the state between jobs. Cold starts and constant load can easily balloon the costs.

Works well in: Connecting directly to databases and APIs holding candidate data. Allows teams to easily drill into records from different data sources. Quick to build dashboards. It wouldn't work well without a team to actually get it set up. There is limited design/ branding, making it look very basic. Your team requires training because data can be overwritten easily. Having some knowledge with your whole team is super important, and if you work with contractors or non-tech people, this can be a huge issue.

• No provisioning required - we don't have to pay anything upfront
• Serverless deployment - it gets executed only when request comes and we pay only for the time the request is getting executed
• Integrates well with AWS CloudWatch triggers so it is easy to setup scheduled tasks like cron jobs

• Ease of use - someone with small amount of experience can use it.
• Adaptability - you can build a lot of things with it.
• Reliability - works quite well.

• Developing test cases for Lambda functions can be difficult. For functions that require some sort of input it can be tough to develop the proper payload and event for a test.
• For the uninitiated, deploying functions with Infrastructure as Code tools can be a challenging undertaking.
• Logging the output of a function feels disjointed from running the function in the console. A tighter integration with operational logging would be appreciated, perhaps being able to view function logs from the Lambda console instead of having to navigate over to CloudWatch.
• Sometimes its difficult to determine the correct permissions needed for Lambda execution from other AWS services.

• Some Retool apps can become slow to load or refresh.
• When multiple team members work on the same app, changes can overwrite each other or break functionality.
• The UI/UX is pretty basic.

I give it a seven is usability because it's AWS. Their UI's are always clunkier than the competition and their documentation is rather cumbersome. There's SO MUCH to dig through and it's a gamble if you actually end up finding the corresponding info if it will actually help. Like I said before, going to google with a specific problem is likely a better route because AWS is quite ubiquitous and chances are you're not the first to encounter the problem. That being said, using SAM (Serverless application model) and it's SAM Local environment makes running local instances of your Lambdas in dev environments painless and quite fun. Using Nodejs + Lambda + SAM Local + VS Code debugger = AWESOME.

Because even though it is quite intuitive it is not the best tool I have ever seen.

Amazon consistently provides comprehensive and easy-to-parse documentation of all AWS features and services. Most development team members find what they need with a quick internet search of the AWS documentation available online. If you need advanced support, though, you might need to engage an AWS engineer, and that could be an unexpected (or unwelcome) expense.

AWS Lambda is good for short running functions, and ideally in response to events within AWS. Google App Engine is a more robust environment which can have complex code running for long periods of time, and across more than one instance of hardware. Google App Engine allows for both front-end and back-end infrastructure, while AWS Lambda is only for small back-end functions

We selected Retool because it offers the best balance of usability and power compared to alternatives like Appsmith, ToolJet, and OutSystems. It allows us to build much faster, with broad integrations and strong enterprise features like permissions and environment management. Competing tools were either too limited, required more engineering effort. Overall, retool support has been decent too.

• Positive - Only paying for when code is run, unlike virtual machines where you pay always regardless of processing power usage.
• Positive - Scalability and accommodating larger amounts of demand is much cheaper. Instead of scaling up virtual machines and increasing the prices you pay for that, you are just increasing the number of times your lambda function is run.
• Negative - Debugging/troubleshooting, and developing for lambda functions take a bit more time to get used to, and migrating code from virtual machines and normal processes to Lambda functions can take a bit of time.

• Major impact - ability to build a backend system is huge.
• Major impact - used every day by multiple people.
• Major impact - ability to be used by less technical teammates.
