Envoy 426 HTTP Issue

Hi Chaps,

I've created Frontent App and Backend app using envoy as sidecar for service mesh.

When I request frontend for backed I get the following directly from envoy:

**http/1.1 426 upgrade required**

Both frontend and backend are Nginx based.

Any ideas ?

Good Open-Source APM tool for php application

Hi Guys

From a long time I'm unable to find a good and easy to setup APM tool for our php application.

I tried using paid tools (new relic, dynatrace, elastic APM), but they'll all end up high cost at the end.

So i'm looking to implement a solution which should be an open-source and should be having good documentation to study with php support. Our application runs on cake php 5.6 (i know it's outdated, but no option to upgrade for now)

So please suggest me something to start. I'm confused by googling this as it shows every tool out their. Not sure where to go now.

Technical books that you actually like (all books WILL be read)

Does anyone have any?

I've read a whole bunch, but the only ones I can think of that I've actually liked are:

* K&R's The C Programming Language
* Learning From Data
* The DevOps Handbook

How should I keep my DevOps Telegram channels interesting yet less noisy?

I started a Telegram channel sometime back to post interesting SRE, DevOps and DevSecOps updates. I mostly share about new new tools and technologies in the market that could be used in your DevOps work. I initially started it as a platform to make notes for myself and soon learned that others also needed it as much. I have about 500 subscribers now. I was not aware of Telegram's channel analytics feature and recently got to know about it. As I checked the graphs, I realized that only 55% on the subscribers were actually viewing the posts actively. All others mostly muted. Also if I posted more than 4 updates in a day, the number of "mutes" would go high on that day.

How do I keep the channel interesting, yet engaging? The question is more about, As a DevOps engineer, what kind of post would keep you more interested and engaged if you were subscribed to one such channel?

I thought of creating a poll and asking in the channel itself, but again those who actually muted the notification would never vote.

How to handle regular spikes in requests?

I have an app which could probably run on Heroku for $50/mo with normal traffic, but I have a few endpoints listening to webhooks and those will get absolutely slammed with tens of thousands of requests when a customer does a batch update. I have basically just been throwing money at the problem but I’m searching for a better solution. I’m not much of a devops person. Could anyone suggest some typical solutions for something like this? I’m willing to move off Heroku.

Test-move traffic from one domain to another a short while, SSL-question

We need to test-run a domain at another hosting company for 30 minutes. The site is ofc https/ssl, and I wonder if I can order a Let'sEncrypt from the new hosting control panel, or will it somehow interfere or disable the original servers SSL certificate for the same domain? I need to point the traffic back after 30 minutes, and don't want anything to break.

They use DNSSEC. Is there anything more to it than just changing A-records?

We will change DNS service to Cloudflare, is there anything I need to think about because of DNSSEC, or just change NS-records with the registrar like usual?

DevOps being a blocker?

I just got some complaints that DevOps and my pipelines are blocking developers code... I’m not sure how to feel, we are the only team in the company that deploys 4000+ a sprint, and a recent issue with a production roll out was caused by multiple code errors by the development team (which they still blamed us...).

How do you deal with this? Are my code coverage checks and quality gates stopping development from being good developers?

Anyone else have similar experiences?? I’m fuming right now because of the amount of time I’ve spent writing and designing systems for all of this is being called a “rusted engine”.... Maybe I am at fault, I should sharpen up.

Free Project Tracking Software

Hi everyone. I hope you are doing well given current Covid-19 epidemic.

Recently I came with idea to search and find possible free alternative to Jira for my company project tracking. Jira is very good software but cost a fortune and it is slow at times.

My company have close to 50 employees and we are growing relatively fast.

What is the best free alternative to Jira? What your company is using for project tracking ?

Is DevOps another business management method?

I recently came across FinOps as a cloud financial management approach and am now somewhat confused by DevOps seemingly plural meanings.

Are there additional cloud business management methods like DevOps and FinOps?

Practical DevSecOps Training and Certification ?

Have any of you ever paid for a training or a certification from [Practical DevSecOps](https://www.practical-devsecops.com/) ?

Would you recommend it or not ?

Would you recommend any other training or certification for DevOps or DevSecOps ?

Look, I'm just going to come out and say it

And you can downvote me all you want but...

Microsoft, within the last couple of years, has really shown a vested interest in expanding the DevOps tools they offer against both their cloud and on-prem platform. PowerShell (my primary scripting language) is just so damn powerful in an all-Windows environment. I feel like just about anything is possible once I've really **dug into and learned** this tool in-depth.

I feel that a lot of traditional DevOps folks don't really spend a lot of time to truly learn the PowerShell platform, and suffer because of it. They try to mold it into a scripting platform they're familiar with, having worked in Bash or Python, and they just don't quite get it - and they misinterpret that as a limitation in the tool and the OS.

I'm thankful that I'm able to build really awesome tools for my team and internal customers, and put together logic structures that are just **so darn good**.

I am a Windows DevOps enthusiast, don't @ me.

Looking to relocate from the UK to the west coast. 2 years of general DevOps experience. What are my chances?

So I have a vested interest in moving to the states, especially the Oregon, Washington states. I visited Portland last year and I really enjoyed it there, feel like I need a change in scenery among other reasons. My general experience involves a year of working with tools such as AWS, Terraform, Ansible, and a lot of the Alatisan product line like Bamboo, Bitbucket, JIRA and alot of bash scripting. Then another year of working more on the container side and Azure DevOps. Finally, I am looking to get myself K8S certified with the CKA exam and teaching myself python.

I guess my question is after the covid situation with my skillset, would it be likely for a company on the west side to take an H1B sponsorship with my skillset? Thanks.

What is the actual impact to the customer?

This may not apply to your workplace, but most places I've worked customer impact is rarely evaluated unless there is a major incident. Even then sometimes a guess is good enough. This comes from working at both large and small companies. I honestly think its kind of a shame because for almost every incident/alert (big AND small) there is some customer impact and this tells us something about the experience of our customers without them having to open a ticket.

I personally think it would make sense to follow up every single alert resolution (even self-recovered) with an analysis of the customer impact that can be tracked over time. This can also be rolled into prioritization if need be.

I'm wondering if customer impact determination is common place for others? If not why don't you care about it that much?

I have several apps that are deployed in one AWS EC2 instance, and I need to deploy several more. Do I deploy everything in one instance? Or do I separate them into different instances?

Basically the title. I'm an intern at a company and new to DevOps, what's the best way to organize deployed apps in AWS EC2 instances??


Deployed apps = (NodeJS API, ReactJS App, VueJS app)
To-be deployed = another reactjs app, and another vuejs app.
