Session 1: Analyzing Cluster Cost using Opencost

主題介紹：

Analyzing cluster cost is pivotal in optimizing infrastructure budgets, especially in cloud environments. OpenCost, a leading tool in this domain, facilitates granular insights into cluster expenditure. By examining resources and their associated costs, OpenCost enables organizations to identify inefficiencies and streamline allocations. By leveraging its capabilities, businesses can achieve a balance between performance and expenditure, ensuring that their infrastructure investments are both strategic and cost-effective.

Session 2: Golang Framework 是怎麼做出這些酷功能？

主題介紹：

在開發中，我們會用到一些 framework 來加速我們的開發，因為標准函式庫提供的功能還不足以滿足需求。常常使用框架也讓我開始思考：這些東西是怎麼做到的？

1. log 如何分級：我們會希望 log 有不同等級的錯誤，像是 info, error, debug... 等等，從許多框架看看做法

2. uber/zap 中的 encoder：把想要的資訊轉換成 json 格式，zap 做了什麼來提高效能？

3. gin 是如何利用「重複使用」這個大方向來提升效能。

4. builder pattern：這是許多框架都會提供給使用者的設計模式，我們會來看看如何實現它。

世界各地的人都不約而同的發明了弓箭，不同的開發者也選擇了相同的作法。學習高手們是如何寫出高效的程式碼，並學習設計模式。

Session 3: 探索 Istio 新型 Data Plane 架構 - Ambient Mesh

主題介紹：

隨著 Service Mesh 的技術在微服務架構下愈發成熟，Istio 逐漸意識到 Sidecar Proxy 不是 Pod 的一等公民，於是決心改變 Proxy 的部署形式，進而去改變 Proxy 無法被生命週期所控制的命運。

本次將會介紹 Server Mesh 面臨什麼樣的挑戰，才得以讓 Ambient Mesh 的 Data Plane 模式被採用，並且深入探討 Ambient Mesh 所使用的組件，去了解其功能以及運作原理。

*: Due to limited venue capacity, this event will be available exclusively through online live streaming.

Hello everyone, this month's Golang Taiwan Gathering will be held at TenLong Bookstore.

First up in our session lineup, Irvi Aini presents "Analyzing Cluster Cost using OpenCost," delving into optimizing infrastructure budgets in cloud environments. OpenCost, a leading tool in this field, offers detailed insights into cluster spending, helping organizations identify inefficiencies and optimize resource allocation.

Next, WeiTheShinobi will introduce "How do golang frameworks accomplish these cool features?" This session will analyze how Go language frameworks implement their unique functionalities, including log level categorization, performance enhancements in uber/zap's encoder, gin's performance optimization strategies, and the implementation of the builder pattern.

Finally, 耿映翔 will guide us through "Exploring Istio's New Data Plane Architecture: Ambient Mesh." This talk will explain why, with the increasing maturity of Service Mesh technology in microservices architecture, Istio has decided to change its proxy deployment approach, delving into the components, functionalities, and operational principles of Ambient Mesh.

Finally, if you have a topic you'd like to share and want to take the stage, we are also open for Lightning Talk submissions (10-15 mins).

===== Session 2 =====

Topic: How Do Golang Frameworks Create These Cool Features?

Topic Overview:

In development, we often use frameworks to accelerate our work, as standard libraries may not meet all our needs. Regular use of frameworks has led me to ponder: How are these features implemented?

Log Level Categorization: We desire different levels of log errors, such as info, error, debug, etc. We'll explore how various frameworks approach this.

uber/zap's Encoder: Converting desired information into JSON format – what has zap done to enhance performance?

gin's Use of Reusability: How does gin leverage the concept of 'reuse' to boost performance?

Builder Pattern: A design pattern offered by many frameworks. We'll explore how it's implemented.

Like the universal invention of the bow and arrow across different cultures, developers often converge on similar methods. Learn how experts write efficient code and understand design patterns.

Speaker: WeiTheShinobi

Speaker Introduction: "With a computer and a cup of fresh milk tea, that's the way of a true expert." An inquisitive seeker, vowed to pursue the magic of coding to its limits.

===== Session 3 =====

Topic: Exploring Istio's New Data Plane Architecture - Ambient Mesh

Topic Overview:

As Service Mesh technology becomes increasingly mature in microservices architecture, Istio has realized that the Sidecar Proxy is not the primary element of a Pod. Thus, it has decided to change the deployment form of the Proxy, thereby altering the fate of the Proxy being uncontrolled by life cycle management.
