Using Azure App Service vs Azure Kubernetes

Is there and advantage to using azure app service with docker container over azure kuberenetes? In the container we can use workers on the gunicorn to scale the app while in AKS we can scale it the kuberenetes way.

I just wonder if there is any situation where you should go for one not the other except in terms of price?

Quick Help with Postman!

Hello! I am very new to this area and have a quick question that can hopefully be answered. I can elaborate as much as needed. Essentially I am trying to run a test in postman that grabs data from the body in a get response to put it in another test. I have tried creating an environment variable but have been messing those up hahaha. Here is a picture that should clarify my question. [https://imgur.com/a/2cn8XXD](https://imgur.com/a/2cn8XXD)

I want to categorize the ID from the body from my get request to my delete request so I don't need to replace the ID every time I invite a user.

Unbiased reviews of CodeFresh

We are making the switch to Kubernetes this year, and we are currently setting up a self-hosted Jenkins/ArgoCD combination for doing builds and deployments. It works pretty well so far, although we still have a lot to do such as secrets management and preview/pull request environments. We chose Jenkins for now because we know it well and make a prototype of anything in it pretty fast, but it has its own set of disadvantages such as lack of high availability and difficulty configuring it as code.

CodeFresh looks interesting as a managed alternative here and seems to support all these things. However I'm having a hard time finding any reviews of this system that have not been written by employees of this company. I'm wondering if there are folks here who have experience with this system, or perhaps found good reviews of actual users of this system?

Starting in AWS DevOps

Currently 2 years out of college with a cyber degree and currently an analyst but I’ve decided i’m going to change my course

I think I know the skills and knowledge I need to build for the DevOps route - networking, python & bash, docker, ansible, kubernetes, AWS architecture and how it all applies (criticize or add to this list if need be)

But in terms of certifications, I know Solutions Architect is definitely a must to get a grasp on AWS as a whole...but would SysOps or Developer be more beneficial to the DevOps route? I would take both but I feel it would be best if i took just one and invested more time in learning the skills above

Is it bad practice to use a config file for user-related permissions?

I have a website. I want to allow certain requests to be made, based on what somebody's username is. So basically before the request is made I will check to see what group they are in, and either allow or deny the request. I will be checking a config file with different usernames/groups listed out. Is this bad practice?

There actually is a relevant distro group available. I did struggle to access this distro group though... let me explain why.

The website architect is that there are three separately deployed repos. An authentication repo (login for when you visit the site). A front end repo. And the backend repo (makes the requests and returns the response). This authentication repo also currently checks a distro group permission. If the permission fails then the site doesn't load at all.

The problem is I'm looking to use distro groups in a much more granular way (for example if you're in one particular group, you can't make one specific request out of many, or can't click one particular button). I asked the devs of the distro group how I could make granular website modifications based on distro group membership. They said in my front end repo I should add code such as

*make request to distro group*
if user is part of distro group:
show additional button / functionality
else:
hide the button / functionality

This made sense to me but I was not able to make the request to the distro group from my front end package. This was attributed to the fact that the website setup involves three separately deployed packages. So all the authentication/distro info was in my auth repo, but I couldn't get it in the front end repo where I needed it.

So after a lot of struggle I gave up and just went with the config file approach.

Does a distributed filesystem have to consist of multiple filesystems located on different computers?

Does the concept of a distributed filesystem require a distributed filesystem to consist of multiple filesystems located on different computers?


Does an NFS filesystem consist of only one filesystem? (See [the diagram](https://i.stack.imgur.com/YTsOy.png))

If yes, is an NFS filesystem a distributed filesystem?

Thanks.

What parts of devops is code you can post on Github? I am trying to understand if you can show how good you are at devops by posting code on Github. It seems like 70% of devops is just using tools, console scripting and code deployed to the Cloud, but that means you can't really post the stuffs you do on Github. Am I wrong? How so?

Load Testing Caddy Web Server on a GCP F1-Micro Instance Using K6 (k6.io)

[https://devopsdirective.com/posts/2020/03/load-testing-f1-micro/](https://devopsdirective.com/posts/2020/03/load-testing-f1-micro/)

**TL;DR:** I used the [K6](https://k6.io/) load testing framework to benchmark the Compute Engine [f1-micro](https://cloud.google.com/compute/docs/machine-types#n1_shared-core_machine_types) and [Caddy web server](https://caddyserver.com/v1/). With CloudFlare caching turned off, the server was able to serve an onslaught 800 virtual users continuously reloading the page (while maintaining a median request duration of <400ms), but started dropping requests when increasing the load further.

Is testing automation part of devops?

Is testing automation part of devops? In my understanding, it's a part of it, but I am unsure what needs to be done to automate it. Let's say you are using Jest, Enzyme for unit and integration testing and Cypress for e2e. What are the tools you would use to automate it and is it all code or do you need to use console scripting and configure a cloud application too to make everything run at the push of a button?

What Slack structure and integrations are you using to support your DevOps adventure?

Where I work most of our notifications and alerts go through Slack, and it works as a primary source of information for everything except for critical alerts, those go through VictorOps.

We mostly use Datadog with its Slack integration, which also sends a message upon resolve. For appplication errors we track and alert via Sentry. Both messages from Datadog and Sentry typically goes to `#<appname>-alerts`. Slacks GitHub bot gives us status on Pull Requests, commits and issues to `#<appname>-notifications`. Jenkins also reports on successful builds and deployments to this channel.

Even though the platform/infrastructure is not an «app», it also has follows the same schema with `#infra-alerts` and `#infra-notifications`.

We use Pull Panda for Pull Request reminders, which is quite effectual.

Each team on the other hand structure their communication around the public Slack channels `#<teamname>-{status,support,social}` in addition to a private team only channel.

There are also two special channels which are just `#alerts` where critical errors are relayed, and it also works as a war room – and `#notifications` where the GitHub bot reports on commits to master on all projects, to broadcast a sense of company feature velocity awareness.

I'm interesting in hearing your experiences and thoughts, thanks!

What differences are between a NAS, a shared disk file system on a SAN, and a distributed filesystem?

https://en.wikipedia.org/wiki/Clustered_file_system#Network-attached_storage says

> Network-attached storage (NAS) provides both storage and a file
> system, like a shared disk file system on top of a storage area
> network (SAN). NAS typically uses file-based protocols (as opposed to
> block-based protocols a SAN would use) such as NFS (popular on UNIX
> systems), SMB/CIFS (Server Message Block/Common Internet File System)
> (used with MS Windows systems), AFP (used with Apple Macintosh
> computers), or NCP (used with OES and Novell NetWare).

https://en.wikipedia.org/wiki/Network-attached_storage

> Network-attached storage (NAS) is a file-level (as opposed to block-level) computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. NAS is specialized for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance – a purpose-built specialized computer.[nb 1] NAS systems are networked appliances that contain one or more storage drives, often arranged into logical, redundant storage containers or RAID. Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB, or AFP.

> ... A clustered NAS is a NAS that is using a distributed file system running simultaneously on multiple servers. The key difference between a clustered and traditional NAS is the ability to distribute[citation needed] (e.g. stripe) data and metadata across the cluster nodes or storage devices. Clustered NAS, like a traditional one, still provides unified access to the files from any of the cluster nodes, unrelated to the actual location of the data.


Does a NAS provide both block level and file level operations?

Does "Network-attached storage (NAS) provides both storage and a file system, like a shared disk file system on top of a storage area network (SAN)" mean that NAS and a shared disk file system on a SAN are the same?

Does "NAS typically uses file-based protocols (as opposed to block-based protocols a SAN would use) such as NFS (popular on UNIX systems), SMB/CIFS (Server Message Block/Common Internet File System) (used with MS Windows systems), AFP (used with Apple Macintosh computers), or NCP (used with OES and Novell NetWare)" mean that NAS and a distributed filesystem are the same?

Amazon DynamoDB Streams - Video Tutorial for the AWS Developer Associate from digital cloud training

Do you fully understand Amazon DynamoDB Streams? This is a popular topic for questions on the AWS Certified Developer Associate exam. This feature of DynamoDB captures a time-ordered sequence of item-level modifications in DynamoDB tables. Other AWS services can then process the data in a stream.

DynamoDB Streams is often used for archiving and auditing, analytical reporting, search, real-time lookup and messaging / notification use cases. In my upcoming course for the AWS Developer Associate, you'll learn several use cases for DynamoDB Streams and get straight to the facts you need to understand for the exam.

In the linked video, which is an excerpt from my upcoming course, you'll also gain practical experience as you follow along and build the architecture working with DynamoDB Streams, AWS Lambda and Amazon CloudWatch.
