How much does serverless development cost?

Instead of renting a server that runs all month, your code sits idle on a service like Amazon's Lambda and costs nothing until a request arrives. That makes the bill follow the shape of your traffic rather than its size. Bursty, unpredictable use is where this is dramatically cheaper. Steady heavy load all day is where it stops being the cheaper option, and we will tell you that early.

How long does serverless development take?

A first working backend of this kind is often a few weeks to a couple of months, because there is no server to set up. Requests arrive through a managed front door, Amazon's API Gateway or its equivalent. The gate is the load test. Neither the bill nor the wake-up delay can be judged from a developer's laptop, so we run realistic traffic before calling it done.

Can you take over an existing serverless backend?

Yes. We start by checking whether the setup is written down as code, so it can be recreated, or whether someone built it by clicking through a console. Clicked-together infrastructure is the expensive case: nobody can say what exists. We also check the time limit each function runs under, because a job near that ceiling usually needs rethinking, not patching.

Have you delivered serverless development projects before?

We build and run backends on this model as ordinary work, and the part that transfers is the operational side: setting a budget alarm before the first deploy, moving anything slow onto a queue, such as Amazon's SQS, so a customer is never waiting on it, and keeping the whole setup describable in code. For named references, ask us directly rather than trusting a page.

What do we own when the serverless backend is finished?

The cloud account is opened in your company's name from day one, so nothing has to be migrated out of ours later. You keep it, the repository, and the infrastructure written as code, which means the whole environment can be rebuilt from scratch if it is ever lost. Budgets and billing alarms are set up before we leave.

Why choose MobileXApps for serverless development?

Much of the online debate about this approach is people who got a surprise bill or hit the wake-up delay in the wrong place. Both are design problems, and both are decided early. We check the function time limit against your slowest job before agreeing an approach, put alarms on spend from the start, and say plainly when an always-on server would serve you better.
