If you need to store files, you are able to use S3 buckets or other cloud storage which works quite nicely. In the next section, I will discuss the Serverless Framework and address the first two bullet points on the list.

Changing cloud vendors will likely require re-writing code.Application code must be stateless (no access to a file system).Managing/organizing code can be difficult.There are also drawbacks to consider when building serverless applications: Variety of options for triggers for running serverless code (API endpoint, message queue, timer, etc.).

Support for many popular programming languages.Simplicity – no managing infrastructure.The benefits of serverless applications are as follows: This results in significant cost savings. For Serverless, you are just paying per request and amount of time your code runs. If you are deploying to a VM you will pay for the entire capacity of that VM for as long as it is running. That is a huge benefit if you are just looking to get an application deployed on a server in a hurry for others to see. All you have to focus on is your application’s code. All of those infrastructure concerns are handled for you. You don’t have to provision a VM or set up automatic scaling. But if you’re running your code on AWS Lambda or as an Azure function, then the server/machine management part is completely abstracted away. If you are running code, of course, there is a server somewhere. What is Serverless Computing?įirst off, the Serverless Application is horribly misnamed. You can view the finished product on Github. Then I will build a Node.js service to do CRUD operations using AWS Lambda, DynamoDB, and the Serverless Framework. In this post, I’m going to briefly touch on what serverless computing is and the pros and cons of using it. Serverless really empowers developers to act on ideas as quickly as possible. Using serverless computing to get up and running takes very little effort and the costs of running an application in the cloud are minimal. The convenience and cost make it a compelling choice for running options in the cloud– Especially for proofs-of-concept or quick ways to prove out ideas. Please keep that in mind as you read the post.Īs a developer, my favorite new technology is serverless computing.

Application Development – We’re a team of developers creating full-stack software applications.

Our team is singularly comprised of software developers and architects-they are elite, vetted employees with strong histories of client acclaim. If you're like me, and you want to create data by copy/pasting code in the command line instead of doing it manually from the GUI, here are some examples.We build custom software solutions that solve complex business challenges. Creating tables and items from the command line Using it is very straightforward so I won’t walk you through it here, but to give you an idea, here are what the screens look like.Ĥ.

Open a new terminal window, and execute dynamodb-admin.

There's an unofficial but user-friendly GUI for DynamoDB Local, called dynamodb-admin (check the link for more detailed instructions). So far I've found it easy to simply create tables/data from the command line each time (I don't have much initial data). If you want the data to persist, it looks like you can use the sharedDB option.

All data in the local database(s) are cleared every time the container is shut down.

And that's it! You can now create tables and put data inside! Enter fullscreen mode Exit fullscreen mode
