Using S3 as Local Storage on kubernetes with S3 CSI Driver

Originally posted on the Israeli Tech Radar on medium.

TLDR; In the world of cloud-native applications, efficient and scalable storage solutions are crucial. Amazon S3 (Simple Storage Service) is a popular object storage service, but what if you could use it as local storage in your Kubernetes clusters? Enter the S3 CSI (Container Storage Interface) Driver, a game-changer for developers and operations teams alike.

Building a Developer Platform: “Behind the Scenes” of application lifecycle management

Originally posted on the Israeli Tech Radar on medium.

In the dynamic realm of software development, particularly within agile and cloud-native landscapes, the ability to swiftly adapt and innovate is paramount. This agility, however, often comes with its own set of challenges, especially when it involves the coordination and management of numerous microservices and processes. Herein lies the crux of our narrative: the establishment of a robust developer platform, metaphorically dubbed “The Show” for its ability to seamlessly present the final act to the audience — our customers — without exposing the countless hours and effort invested backstage by developers and operations personnel.

Doing literally anything with go-task and why should ya?

This is a common approach I adopted to manage tasks

From yak shaving to mastering tasks

TLDR; This is a quick share of a neat tool which found it’s way into my toolset, it did it in such a significant way which enabled me to combine tools in a common way — something I’ve been missing for quite a while. This is also a thank you to the author’s and contributors of go-task which is such an awesome tool.

Kubernetes Control Loops: The Secret Sauce Behind Your Microservice Bliss

Originally posted on the Israeli Tech Radar on medium.

TLDR; Ever dreamt of a system that manages your microservices like a maestro, constantly keeping them in perfect harmony? Kubernetes makes this a reality with control loops, the magic behind the scenes. Operators take it a step further, letting you customize Kubernetes for even more control over custom workload needs.

Kubexperience for developers

Originally posted on the Israeli Tech Radar on medium.

TL;DR Kubernetes is much more than just a container orchestration platform … alongside The Cloud Native Landscape Kubernetes is the equivalent to Linux’s kernel with an ecosystem of apps/util which enriched it.

Managing your dotfiles or ~/.config ...

This is a common approach I adopted to manage my dotfiles

Pre-commit hooks using python library pre-commit

Pre-commit examples used in just-do-it repository

I really need a strict pre-commit considering the number of branches and tools i’m using. Because the heart of the projects is tasks I want at the bare least .pre-commit-config.yaml to include the task --list-all command considering it compiles all the includes which may change name / location between branches.

Dev Env Evolution: Seeking developers productivity, Webinar

In this webinar we had two talks:

DevEnv Evolution - Seeking Developer Productivity// Haggai Philip Zaguri, DevOps Architect, Group & Tech Lead at Tikal

Have You built your Developer Platform yet? TechRadarCon Talk

In this talk, I will try to emphasize the adjustments both Cultural alongside the technological ones which any “Cloud-Native Dev” should adjust to in the CloudNative Era. Whilst cloud Environments and Various Architecture styles, such as Serverless and Micro Services, and their effective Deployment schemes, which seemed to have designed a way to deal with the Operational Overhead, by seteling for a blend of work-styles which enable to choose or invest more wisely, the cloudNative development experience has shifted … Engineering platforms are emerging like mushrooms after the “microservices rain”, some have been building one for quite a while

DevEx | GitOps & ArgoCD, Meetup Tikal & Ownbackup

In this talk we will cover the ci-cd processes shifting to GitLab and ArgoCD, and how our implementation provides shorter feedback loops which are key in speeding-up the overall developer experience.

Chef & Vagrant for Dev-in-DevOps, Meetup (Workshop)

Developing a Webcam Arcade Controller using Deep Learning by TensorFlow & Keras - part 1, Meetup

We will introduce Deep Learning, demo a DL model in action, introduce an architecture for training and use of such model in a production environment, and show some critical sections of the code. Demo - Control video game using Deep Learning (15 min) - by Haim Cohen, Big Data Architect from Tikal. We will demo an application which makes use of deep learning in order to control a video game through webcam and head gestures. Lectures: Deep Learning - Starting Now (20 min) - by Shai Tal, Data Scientist and Machine Learning Engineer from Tikal. Deep learning is a tool. And tools need to be understood. We will briefly discuss the practical benefits of machine learning over programming, and the benefits of deep learning over classic machine learning for building visualisation and NLP models. Deep Learning API’s & Architecture (30 min) by Haim Cohen. We will Introduce TensorFlow & Keras through code examples, go through main parts of the demo application and talk about the architecture of the demo application and other Deep Learning based systems.

Cloud Native Devs!, TechRadarCon Talk

Cloud Environments and Architectures, such as Serverless and Microservices, and their effective Deployment and Stability of Production have been our main focus, but we are now seeing the developer experience shifting. Forced to combine many subsystems together on our laptops it has become a mirror of the cloud. We used to call this our Integrated development Environment, and we should start treating it as one. In this session, we will take a short tour of many patterns & tools designed to enhance the developer experience. From various integrations augmenting our existing IDE’s to Internal Development Platforms designed as self-service platforms for developers.

A CloudNative Dev Experience 🎯 | Tikal TechRadarCon 2021

Originally posted on the Israeli Tech Radar on medium.

TLDR; Just when we thought we’ve got it figured out! We learn there’s a better, faster way of doing things, frameworks, abstractions, and methodologies invented to make our development experience easier, and help us during our journey to building a platform. But…Do we really need one?/Should we adopt one? What impact will that have on our product? The following post will try to tackle some of these questions as we explore building a better Developer Experience.
