Good to hear that we agree on the ideas in the list! These timeless ideas from our current knowledge are exactly what I’m trying to identify. Let me know if you can think of more

I’ve included the halting problem, but omitted the Turing machine, because while ingenious, the latter is simply a hack to make proofs work and not a very good way to think about computation. Similarly, I’ve included distributed representat

Provisioned lambdas make sense if you set the capacity to your median load to save money. But you still want the snappy horizontal scaling of lambda for loads above the median.

The value of serverless is in commodified operations: once you wrote the code, it’s your favorite cloud provider’s problem to run it. This lets you provide high-availability services without a 24/7 on-call rotation. RDS and Fargate are

I love Clojure and take every chance to use it, but unfortunately it’s very much behind the curve. Building web apps is more and more about tying together managed services with short scripts (aka serverless). This means that most app develo

Well, given the feature set of API Gateway compared to a Load Balancer I think it should be expected that it costs more. But that’s also beside the point which is to use managed services to do the heavy lifting. Eg. if you need a PubSub ser

If you use Cognito for identity management, then there isn’t even need for that. You can just assign users the appropriate IAM role and you can upload directly from the front end.

These are usually the read N items from a database type of queries that GraphQL makes trivial to batch together. Will barely increase response time, but will provide a better experience for users on bad connections.

Think about serverless as framework-as-a-service. It has a learning curve, but if you buy in, it is an amazing productivity boost. (If Reddit’s video hosting being built and operated on a serverless stack by a single a engineer won’t convin

The internet is full of success stories if you care to look. My favorites: - iRobot (maker of Roomba) has been running its entire IoT stack serverless since 2016 (architect Ben Kehoe is a worthwhile follow on Twitter) - Reddit’s video hosti

Saves time and money by writing and executing less code + S3 is optimized for this task, so it will always perform better than an ad hoc serverless function.

Lambda is 5 year old technology. This is like arguing in 2011 that startups shouldn’t use EC2, because it’s “risky”.

> Serverless only makes sense if you have a fairly trivial problem That’s exactly the point. The web application needs of most startups are fairly trivial and best supported by a serverless stack. Put it another way: If your best choice

I don’t think it’s possible to produce empirical evidence to prove or disprove this claim, but it’s just common sense: Using managed services leads to writing less code and minimizing devops work, both resulting in more time for feature dev

If you have 10m requests uniformly distributed, then yes it’s less of a problem, but that’s unlikely. (Even then lambda containers will be recycled multiple times throughout the day, so there is still a small penalty.)

I don’t think anybody advocates for rewriting all existing projects as serverless. But if you’re starting a startup, going all in on serverless will let you deliver better products faster. If Paul Graham’s Beating the Averages would be writ

PSA: porting an existing application one-to-one to serverless almost never goes as expected. Couple of points that stand out from the article: 1. Don’t use .NET, it has terrible startup time. Lambda is all about zero-cost horizontal scaling

Think of serverless as “framework-as-a-service”. Edit: why the downvote? From infrastructure, through platform, serverless is the natural evolution of the cloud to framework-as-a-service.

What exactly are you looking for? I think Pytorch is so ergonomic that there is no need for other resources. The only gotchas I found were in the data loading utilities.

This article makes such a strong case for ditching k8s for serverless: - needs granular scaling - devops expertise is not core to the business - save developer time

The question is not the relative price of the goods, but the extra cost incurred by the majority to accommodate the minority. This might be hard to discern from the anecdotal style of the book, but this is the third most important factor af
