Serverless application with Lambda

Building your application with serverless technology can save you a lot of time and money. This is because serverless architectures usually come with less of an administrative burden than regular cloud architectures. Less, though, doesn’t mean zero. You can’t just throw a few functions into the cloud and hope that everything will work out okay. There are a few things you still need to consider to keep your system operational, secure, reliable, performant, and reasonably priced.

One thing you’ll want to think about is how much storage space you need for each Lambda function. If your function needs a lot of data storage space—for example, if it needs to store large files or process images—you may want to move it into its own container instead of using the default one that comes with every Lambda function. This way, you won’t have any bottlenecks or slowdowns in your application as a whole due to memory or disk usage issues with other functions.

A second thing you might want to do is restrict access for Lambda functions so users can only use them on their local machine(s). This prevents external users from accessing private information or services without permission from their owner (you!).
