Frequently asked questions.

How do I subscribe to Up Pro?

View the documentation for a guide on subscribing to Up Pro. Commercial use requires an Up Pro subscription for the duration of its use in production.

Is this a hosted service?

Up is a self-hosted service, letting you deploy applications to your own AWS account for isolation, security, and longevity — don’t worry about a startup going out of business.

How is this different than other serverless frameworks?

Most of the AWS Lambda based tools are function-oriented, while Up abstracts this away entirely. Up does not use framework “shims”, the servers that you run using Up are regular HTTP servers and require no code changes for Lambda compatibility.

Up keeps your apps and APIs portable, makes testing them locally easier, and prevents vendor lock-in. The Lambda support for Up is simply an implementation detail, you are not coupled to API Gateway or Lambda. Up uses the API Gateway proxy mode to send all requests (regardless of path or method) to your application.

If you’re looking to manage function-level event processing pipelines, Apex or Serverless are likely better candidates, however if you’re creating applications, apis, micro services, or websites, Up is built for you.

Why run HTTP servers in Lambda?

You might be thinking this defeats the purpose of Lambda, however most people just want to use the tools they know and love. Up lets you be productive developing locally as you normally would, Lambda for hosting is only an implementation detail.

With Up you can use any Python, Node, Go, or Java framework you’d normally use to develop, and deploy with a single command, while maintaining the cost effectiveness, self-healing, and scaling capabilities of Lambda.

How much does it cost to run an application?

AWS API Gateway provides 1 million free requests per month, so there’s a good chance you won’t have to pay anything at all. Beyond that view the AWS Pricing for more information.

How well does it scale?

Up scales to fit your traffic on-demand, you don’t have to do anything beyond deploying your code. There’s no restriction on the number of concurrent instances, apps, custom domains and so on.

How much latency does Up’s reverse proxy introduce?

With a 512mb Lambda function Up introduces an average of around 500µs (microseconds) per request.

Can I remove the /staging and /production paths?

Up uses AWS API Gateway, which imposes the stage base paths. Currently there is no way to remove them, however when you use custom domains these paths are not present.

Do the servers stay active while idle?

This depends on the platform, and with Lambda being the initial platform provided the current answer is no, the server(s) are frozen when inactive and are otherwise “stateless”.

Typically relying on background work in-process is an anti-pattern as it does not scale. Lambda functions combined with CloudWatch scheduled events for example are a good way to handle this kind of work, if you’re looking for a scalable alternative.

Which databases can I use?

You’re not limited to databases from any given platform, such as AWS Provided that the database host provides authentication, you can use anything. See the Wiki for a list of managed & serverless database solutions.
