There are two reasons to optimize AWS Lambda functions performance. First is money – you pay for the Lambda execution duration. The quicker you do the job, the less you pay. The second is latency – the quicker you do the job, the shorter your client waits for the result. It’s a known fact that the decrease of latency improves sales, user engagement, and client satisfaction – so we could argue it’s also the money, in the end.Read more »

Logging in AWS Lambda functions is simple. You just print the message, and it’s sent to the CloudWatch Logs. And everything is fine until you get a surprisingly big bill for the CloudWatch usage, or you need to actually debug some live system. Here are my tips for logging in AWS Lambda, based on my experience with real-live, big-scale functions running on production.Read more »
Welcome to the first issue of Things I Found Interesting – an irregular series of links to, well, interesting content. Below are eleven articles and resources on various software-related topics, which I stumbled upon in the last several weeks.Read more »
Buckle up, for some of you this may be controversial, but maybe for some others – obvious. This is how to prevent a problem causing your application to out of the sudden stop behaving correctly, or, even more funny, stop behaving correctly only on one developer’s computer. We can solve this with
one two simple tricks.
Here I show three ways to create Amazon Athena tables. More importantly, I show when to use which one (and when don’t) depending on the case, with comparison and tips, and a sample data flow architecture implementation. Also, I have a short rant over redundant AWS Glue features. All in a single article. Enjoy.Read more »
Bash scripts. Almost anyone needs to write one sooner or later. Almost no one says “yeah, I love writing them”. And that’s why almost everyone is putting low attention while writing them.
I won’t try to make you a Bash expert (since I’m not a one either), but I will show you a minimal template that will make your scripts safer. You don’t need to thank me, your future self will thank you.Read more »
There are multiple articles on how to host a static website or Single Page Application (SPA) on AWS. But they rarely go into the topic of setting up the environment variables for the frontend application.
Let’s look beyond the part where most tutorials end – with the website deployed, how to parametrize it to call correct backend APIs and resources. We will look at the usual deployment process and improve it. In the end, the application will automatically reference the services from its own environment, both when deployed and locally.Read more »
Developers, like all specialists, discover and collect their favorite tools over time. Having a good, proven set of tools makes the work easier and more pleasant. We can focus on getting the job done. Sometimes eliminating minor inconveniences or improving a small element of everyday activity makes the greatest impact on the comfort of work.
It’s not always easy to find the best tools. There is a wide choice. More importantly, everyone has different habits and preferences. The best way is to test them yourself and see what suits you.
To help a little bit with that, here I present a collection of my AWS tools. These are applications, plugins, and extensions that I use in my daily work with AWS.Read more »
