I plan to write a series of posts about databases internals. In order to make it easily perceivable, I’ll be writing a NoSQL DB from scratch in Ruby. No doubts that it’s not the best fit for database development, but it’s extremely readable and will help us a lot. This one will be about why may you want to have an index and what is a Hash index.
UPD. I decided to not continue this series because it takes too much effort to investigate deep enough to explain, but it had got much fewer views and likes than more applicable ones. Probably will return to this topic once, but not now.
If you followed my 3 my previous posts – you already created your first Amazon Lambda function, made it able to write to DynamoDB and be accessible from the outside world, using API Gateway.
In this post, I will guide you how to implement the same but without touching the AWS Management Console, which is barely understandable and very volatile by the interface. Instead, we will be using Terraform, which I also covered in the past blog post.
Let’s get started:
In this post, we will create a Lambda function which can write to the Amazon DynamoDB table. For this, we will create a table, modify existing function and set up IAM roles. Log in to your AWS account and let’s get started!
This post is the second one in series about Amazon Web Services first steps howtos.
I believe that traditional guides like AWS Certification preparation and Linux Academy don’t give the information in proper order, so here I give it in the format and the way how I give it to my colleagues at Babbel.
This post gives you an introduction to the DynamoDB and prepares a ground for the next practical lesson.
I just started AWS Learning Sessions in the company, I’m currently working in, and want to share with you our first lesson.
We have built small Lambda function, named Greeter, and integrated it to the AWS API Gateway.
If you want to get started with this tools and get some hands-on experience – this article will help you.
Not a long time ago I had no idea about what is the tool named Terraform. It was just beyond my bounds of interests and problems. But a month ago I changed a company and then had to deal with it. And guys, it’s wow. It’s so amazing thing so I even started liking DevOps job.
In few words it’s a tool to do infrastructure as a code. As they say on their website “Terraform enables you to safely and predictably create, change, and improve production infrastructure”.
In this post, I’ll cover why may you (as a developer or a DevOps) need it and how to get started. Getting started will be not just a hello world, but a real example, you can try right away.
Today I’ll talk about really trivial thing, but unexpectedly I found myself living without it for a while, but now I started using it and cannot stop anymore %)
The thing is Docker.
