Colorkrew Blog

Overview

As remote work continues to grow in popularity, more companies are adopting flexible policies to accommodate employees’ varying needs. For many people, especially those from other countries working abroad, the ability to work from their home country for a short period is an invaluable benefit. I recently had the opportunity to experience this firsthand, and I’d like to share my experience, how my company’s policy works, and the benefits of this flexibility for foreign employees.

It can be hard to define what makes a “good” team lead, but you can always strive to be a better one. Since joining Colorkrew, I’ve taken on the role of Team Lead for our Workflow product, managing the team to ensure our work progresses smoothly and that we create the best products for our customers.

During AWS re:Invent 2024 AWS released a new feature to EKS i.e EKS Auto Mode, which I have already covered in detail in my previous blog

In this blog we will see how we can create cluster with EKS Auto mode using the OG “terraform-eks-module” and how it simplified my eks.tf code.

AWS re:Invent has begun and there are tons of new service and feature announcement from the AWS CEO Matt Garman’s Keynote ( check my x/bluesky thread from the keynote updates)

In this blog we will investigate about Amazon Aurora DSQL which is serverless, distributed SQL database with virtually unlimited scale, high availability, and zero infrastructure management claiming 99.99% single-Region and 99.999% multi-Region availability.

AWS re:Invent hasn’t officially begun, yet there is a game changing new feature to EKS to make you run Kubernetes like a pro!!!

In this blog we will investigate what EKS Auto Mode is all about and illustrates how to enables EKS Auto Mode on existing cluster and try to migrate to our managed node groups workloads to EKS auto mode of an existing cluster but we will be not able to do that, find out why in the blog!

Tired of setting up CodeBuild just to push Docker images or run vulnerability scans?

With AWS CodePipeline’s new ECRBuildAndPublish and InspectorScan actions, you can now build, publish, and secure your images directly within your pipeline—no extra setup needed. Curious how it works? Let’s dive in!

Motivation

26 November, 2024 – Just ahead of re:Invent 2024, AWS released an exciting update introducing ECRBuildAndPublish and InspectorScan actions. This update simplifies building and publishing Docker images, letting your pipeline handle it seamlessly.

This blog is little unusual than the usual “show-what-you-built” blogs which we usually see for cloud services and new features on the internet.

In this blog I will sharing my first impressions, good and bad points about the new update on Cloudwatch: Observability Solutions !!!

AWS CloudWatch Observability Solutions aim to simplify monitoring setup with pre-configured tools for AWS services and workloads. But is it really that straightforward? Let’s explore the reality!

In Japan, many companies hire new graduates in large groups every April. However, Colorkrew hires throughout the year. This October, we welcomed two talented new graduates to our team.

One joined as an engineer, and the other joined the business team, working in product operations. One graduated from a university overseas, and the other graduated from a university in Japan.

We all love serverless especially when it comes to AWS LAMBDA functions.

There are good reasons to do so for event-driven, decoupling, automation and many other reasons that time aws lambda was released.

But there can be situations when our dear friend LAMBDA can turn in to a foe and cost us money, downtime and those times are unintentional recursive Loops.
In this blog we will talk about a very simple feature yet a powerful one, recursive loop detection between aws lambda and s3 bucket.

Until Now, if you wanted to run AWS CLI commands, third-party CLI commands, or simply invoke an API, you had to create a CodeBuild project, configure the project with the appropriate commands, and add a CodeBuild action to your pipeline to run the project.

Clearly Users had to deal with 2 components CodePipeline and CodeBuild and of course learn the internals for both in order to use the.

This is Lucky Li, I joined Colorkrew as a new graduate from April.

My position is Engineer, belonging to the Colorkrew Biz product team. My work is developing Colorkrew Biz which is a well-know Saas in Japan.

Before I joined, I conducted academic research and pursued a PhD at the National University.

What data structure would you use to determine whether an entity is in a given dataset with speed? Many would answer “Hashtable” without hesitation. Hashtable performs well when accessing an entity among a group of entities: the average time complexity of its read operations is constant. Nevertheless, using Hashtables can be rather costly when dealing with large datasets. Hashtables need to keep track of every entity in the dataset, resulting in a linear space complexity.

Moving to Japan

The first time I came to Japan, I was a tourist. I spent 1 week here during my final year of college.

The second time I came to Japan, I was moving here, starting a new job and a different way of life.

In the 7 years between, I worked as a software engineer across many American cities and companies.

Time flies and we have entered 2024. And I had joined Colorkrew for 3 months. I am filled with excitement for what the future holds.

My last job was as the director of a multinational e-commerce company. Although the company has gone public, it still maintains the atmosphere of a start-up company.That is also the reason I decided to join Colorkrew.
