影響: 存取服務會花上高達十倍的延遲時間

這篇文章準確的說，問題其實跟 Kubernetes 本身關係不大，反而是遷移 Kubernetes 到系統中常見的溝通問題。作者的標題是真真實實來自 Dev Team 的回饋，當應用程式搬移到 kubernetes 後得到的效果不如預期，也許最後不是 kubernetes 的問題，但是 SRE/DevOps 還是得必須針對這些質疑去探討，找出最後真正的原因。

作者團隊當初要將一個微服務從 EC2 上給整合到 Kubernetes內，卻發現存取該服務的延遲性相對於直接部署到 EC2 上大幅度上升十倍。根據團隊的調查，EC2 的應用程式只需要 20ms 左右回覆請求，而 kubernetes 版本則需要 200ms 左右。

最後來來回回除錯找到問題根源，主要是 AWS Jave SDK 裏面的用法於不同的情境下會有不同的效果。其於 Kubernetes 下會發生每個 request 都強迫去刷新當前的 certificate 資訊，因此每個 request 都還會額外發送一個新的 request 去取得 certificate。

基本上整個問題都跟 Kubernetes 的架構無關，單純是 AWS 架構的用法，如果你有使用 KIAM 相關的服務，同時也有使用 AWS Java SDK，可以參考本篇的問題

眾籌支付誹謗案相關費用
還原721襲擊真相
Crowdfunding Campaign for paying fees in the defamation case
Restore the truth of 721 Yuen Long Attack

2019年7月21日，相信不少人對當晚元朗所發生的事仍舊歷歷在目，亦改變了不少人的一生。我在當晚於手機、電視目擊住於元朗發生的一切，因而決定挺身而出，再次躺進這趟政治渾水，參與區議會選舉，為掃除建制惡勢力出一分力。然而，即使當上區議員，政治打壓令我們工作舉步為艱，我亦在近日收到昔日選舉對手的誹謗案入稟狀。

在此艱困的狀態下，我沒有退讓的空間，只能選擇迎難而上，將事實在法庭當中陳述。我會善用法庭審訊的機會，將有關721事件的真相在法庭審訊羅列出來，將其作為事實核證的一大平台。我亦會把握機會在傳召證人和盤問過程，將721事件的種種疑團，包括事前流傳的信息真確性、白衣暴徒的關係網、政商關係網絡於審訊中一一揭露，真相愈辯愈明。

作為獨立民主派，我並無任何組織支持，亦沒有昔日選舉對手的龐大財政資源。由於法律援助並不涵蓋誹謗案件，我需要一力承擔有關法律經費（包括聘請律師與大律師的費用、法庭相關費用等）。在面對沉重的財政壓力下，我需要向大家籌募訴訟的經費，以應付相關的開支，懇請大家能夠鼎力支持。我將會利用籌募到的款項，用作法律費用和眾籌平台開支之外，同時亦會聘請一名員工專責搜集721證據及重溫不同媒體片段，以助法庭審訊和其他721事件民間調查工作。

假如我最後獲賠訟費或有盈餘，我會將有關餘額和盈餘撥捐予抗爭者支援組織。

A lot of us still relive what happened in Yuen Long on July 21, 2019, as it changed the lives of countless. After witnessing what happened there that evening via live streams on my phone and television, I chose to step forward and, again, devote myself to the political orbit. I thus participated in the district council election and committed to the eradication of the pro-establishment evil forces in the legislature. However, political repression still exists in the district council and hurdles our work - I just received the summons of the defamation suit filed by my former opponent in the election.

My only way out in this time of adversity is to present the facts in court, where I can make use of the court trial as a fact verification platform to state the truth of July 21. I will also seize the opportunity in the process of subpoena and testimony to expose the qualms of July 21, including the authenticity of the information circulated beforehand, the network of the white-shirted thugs, and the complex business-government relationships.

As an independent democrat, I do not have any organizational support, nor do I have vast financial resources as my late opponent does. Besides, since the legal aid scheme does not cover defamation cases, I must pay the legal expenses, including the cost of hiring lawyers and barristers and court fees, on my own. In the face of tremendous financial pressure, I must plead for help by raising funds for litigation from you to meet the legal expenses. I will use the funds for the legal services required and hiring an agent to collect evidence and review media clips of July 21 to help court trials and other private investigations concerning the incident.

If there is a surplus in the final reimbursement of litigation costs, I will donate the remaining balance to the organisation or fund supporting activists.

眾籌目標：80萬

Congratulations to me!!I finished all my written and practical esthetic examinations last week. I am a licensed Aesthetician in USA.

As your request, you want to have more organic and safe skincare products.I found a all in one serum - Hylunia Beyond Complex C.

Let me talk about Hylunia's background. It was formed in 1988. The founder is Dr Link. He could not find any organic and safe skin care products for his daughter who broke out in hives and rashes. Thus he formed his company with dermatologists, physicians and scientists to provide top quality, organic, safe and pure skincare line. Their products are free of Parabens, Grapefruit Seed Extract, Sodium Lauryl Sulfate (these three ingredients are always related to cancers), Phthalates, Propylene Glycol and Fragrance (these three ingredients are strong skin irritants that are linked to sensitivities and allergic reactions.

Hylunia Complex C can help you to hydrate, whitening, brightening your skin, minimize the fine lines and wrinkles, retard free radical damage. I have used this Beyond Complex C for three months. I found that my wrinkles in forehead and few freckles were gone. Also, my skin tone was more even. You can apply it around your eyes for removing the fine lines around your eyes.

Since Hylunia Beyond Complex C is a safe products, it is highly recommend for you to use every night especially those who are received Laser, IPL and micro needle treatment. And it is safe for those who have sensitive skin and even for pregnant women. Use only one pump for each time.

Since their products are free of those chemical bad ingredients, those products can also improve your body's immune system.
