Agile Project Management - INTRO [Czech Version]

Co je Agile Project Management a proč byste měli znát knihy The Phoenix Project a The Unicorn Project

Když se dnes řekne agilní projektové řízení, spousta lidí si představí Scrum meetingy, Kanban tabule a nekonečné množství nových buzzwordů. Jenže skutečný smysl agility je mnohem hlubší – jde o schopnost firmy rychle reagovat na změny, dodávat hodnotu zákazníkům a nebýt paralyzována vlastní byrokracií a procesy.

A právě tohle téma velmi dobře vysvětlují dvě knihy, které se staly doslova IT bestsellery:

Part #1 – The Phoenix Project
A Novel about IT, DevOps, and Helping Your Business Win

Part #2 – The Unicorn Project
A Novel about Developers, Digital Disruption, and Thriving in the Age of Data

Nejste v tom sami

Obě knihy formou příběhu ukazují realitu, ve které se dnes nachází většina středních a velkých firem. Neustálý tlak na rychlejší dodávky, hromadící se technický dluh, přetížené IT týmy, nekonečné priority „na včera“ a pocit, že systém je tak složitý, že už ho nikdo plně nechápe.

To nejdůležitější poselství je ale uklidňující:

Nejste jediní, kdo je v takové situaci. 

V podobném chaosu funguje obrovské množství organizací po celém světě.

Právě proto se z těchto knih stal fenomén. Lidé v nich poznávají vlastní každodenní realitu – jen je podaná zábavnou a srozumitelnou formou.

Platform Engineering - SLA vs SLO & Platform Org Chart

When building and operating platform services—whether it’s cloud hosting, APIs, or IT support—you’ll often hear the terms SLA and SLO. They might sound similar, but they serve very different purposes.

U.2 vs E3.S SSD: What Is the Difference?

When choosing enterprise NVMe storage for servers and data centers, two form factors are commonly discussed today: U.2 and E3.S. Although both are designed for high-performance and high-reliability workloads, they differ significantly in physical design, scalability, cooling, and long-term viability.

This article explains the key differences in a practical and easy-to-understand way.

Do I Need EVPN L3 Routing If L2 over L3 Is Enough?

When designing a modern data center network, a very common architecture today is L3 underlay + VXLAN overlay + EVPN. 

Sooner or later, however, the following question comes up:

Do I really need EVPN L3 routing (L3 VNI) if I only need Layer 2 connectivity over a Layer 3 network?

The short answer is: no, you don’t.
The longer and more important answer is when it makes sense and when it doesn’t. 

That’s exactly what this article explains. 

Introduction to Netris Network Automation and Abstraction Platform

If you have ever built or operated a real network, you already know the problem: networking is often the last part of the infrastructure that still relies on manual work, device-by-device configuration, and vendor-specific CLI syntax. While compute and storage moved towards automation and declarative management years ago, networking often lags behind. 

Here are two introductions videos ...

In this post, I want to briefly introduce Netris and explain why it is interesting from the perspective of modern, automation-driven environments.  

What is an FRR Router?

What Is a Free Range Routing (FRR) Router?

The term “FRR router” appears frequently in enterprise, datacenter, and ISP networking discussions. Despite how it sounds, it is not a product name and not a hardware device.

What Is Free Range Routing?

Free Range Routing (FRR) is an open-source routing software suite. The name Free Range reflects its original goal: routing software that is free, open, flexible, and not tied to proprietary hardware.

FRR provides implementations of major dynamic routing protocols and runs on general-purpose operating systems such as Linux and FreeBSD.
