AWS Lambda
[AWS Lambda] is very well suited for the projects that doesn't have any infra but needs it where short running processes are required. But if your application need to run continuously than this might not be the very apt tool for you.

OutSystems
Well suited for internal exposure of business processes (invoicing, API layer to other systems, customer maintenance etc), whether a UI is required or not.Not so well suited for full fledged web design. An OutSystems application must serve one particular business need, if gets too much functionalities and responsibilities it tends to get chaotic and complex.

AWS Lambda
- Lambda provides multiple methods for triggering functions, this includes AWS resources and services and external triggers like APIs and CLI calls.
- The compute provided my Lambda is largely hands off for operations teams. Once the function is deployed, the management overhead is minimal since there are no servers to maintain.
- Lambda's pricing can be very cost effective given that users are only charged for the time the function runs and associated costs like network or storage if those are used. A function that executes quickly and is not called often can cost next to nothing.

Cons
AWS Lambda
- Putting a significant portion of your codebase into AWS Lambda and taking advantage of the high level of integration with other AWS services comes with the risk of vendor lock-in.
- While the AWS Lambda environment is "not your problem," it's also not at your disposal to extend or modify, nor does it preserve state between function executions.
- AWS Lambda functions are subject to strict time limitations, and will be aborted if they exceed five minutes of execution time. This can be a problem for some longer-running tasks that are otherwise well-suited to serverless delivery.

OutSystems
- Price – The licensing model of OutSystems is very expensive and not suitable for small scale developments. This is offset by the time to develop and stability for larger scale developments
- Flexibility on PaaS version – The PaaS hosted version of OutSystems limits your flexibility to access the front end and backend database systems which can significantly restrict your options on high data volume developments or where anything requiring slightly out of the ordinary access is required
- Same price for PaaS and self-hosted system. Licensing model dictates that you pay the same price even when you host the system on your own hardware which effectively means you pay more to manage the infrastructure yourself

We are very happy with OutSystems and our developers deliver good work. OutSystems lets us build new software on a regulare (2 weekly) basis, which is highly flexible and adjustable. Even without very much experience, our developers manage to build usefull software, which is working a lot better than our previous (legacy) software.

Usability

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.

I am really happy using OutSystems in my work. It gives me the opportunity to create good working software without having had very much IT-experience before. It also made me more interested in the background of IT and learning different languages.

I have not needed support for AWS Lambda, since it is already using Python, which has resources all over the internet. AWS blog posts have information about how to install some libraries, which is necessary for some more complex operations, but this is available online and didn't require specific customer support for.

The tech support is very reachable. Usually by [email] from but also by phone if needed. We had some difficulties at the start with understanding "what our machine was doing" under high performance load. After some good sessions understanding our needs they delivered good solutions for our problems we had in the beginning.

In a large company, patiently and consistently work the behind the scenes politics with business and IT partners across the firm.
This is transformational - you will need a solid set of key business partners to lock arms together to move forward.

AWS Lambda
Azure Functions is another product that provides lambda functionality, but the documentation for some of Azure's products is quite hard to read. Additionally, AWS Lambda was one of the first cloud computing products on a large cloud service that implemented lambda functions, so they have had the most time to develop the product, increase the quality of service, and extend functionality to more languages. Amazon, by far, has the best service for Lambda that I know.

I tried to use WordPress with some success. Also looked at Joomla. But when I saw OutSystems I knew I had been wasting my time there. It takes you longer to get going with OutSystems - but even I as a novice realized immediately that Outsystems is simply in another league. Outsystems is powerful. (Can you compare WordPress and Joomla to Outsystems - I don't think so).

Return on Investment
AWS Lambda
- I was able to perform a lot of processing on data delivered from my website and little or no cost. This was a big plus to me.
- Programming AWS Lambda is quite easy once you understand the time limits to the functions.
- AWS Lambda has really good integration with the AWS S3 storage system. This a very good method of delivering data to be processed and a good place to pick it up after processing.

- The ease of use of the OutSystems development process has been the biggest ROI for us. We have developed our Framework product and maintained/enhanced it with only 4 workers.
- OutSystems has enhanced their product very significantly over the last 4 years. They have gone from a simple to use tool to a very simple to use sophisticated tool that covers the standard mainframe-based computing apps and the apps used on handheld mobile devices all using the same basic set of development tools.
