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?

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.

Junior DevOps Engineer, recommended learning to advance my career?

I've been an infrastructure engineer for the past 6 months, I manage Jenkins pipelines for our developers and many linux servers. Its been quite rough since I was new to pretty much everything, just had some basic linux skills so had to get lots of help with every issue from other engineers.Because of the holidays I have time to take some courses and can really ramp up my skills.

I'm lucky to have access to [linuxacademy.com](https://linuxacademy.com), a few Linux Foundation courses, and O'reilly courses.I need to get good at Bash Scripting, Linux in general, and writing Groovy scripts for Jenkins pipelines.Example course: [system admin guide to bash scripting](https://linuxacademy.com/cp/modules/view/id/72?redirect_uri=https://app.linuxacademy.com/search?query=scripting), [Oreilly Jenkins course](https://learning.oreilly.com/videos/practical-jenkins/9781788398749/)

I have about 2 weeks to deep dive into any topic, so I want to make sure I'm taking the best courses. We also use a lot of Redhat products so RHCE could be something of interest. I'd also like us to move to an automated setup with Terraform, Ansible and Jenkins all working together so all these skills could be useful. Thanks for any suggestions.

Does scaling depends only on load/ traffic in cloud?

Does scaling only depend on increase of traffic or load of a resource or can scaling depends on other needs?

Are there any other reasons to scale an application on cloud?

USING DOCKER CONTAINERS TO RUN ANSIBLE AND TERRAFORM CODE

Hello everyone, I think this is my first post on here so go easy as I'm relatively new. I'm part IT, part programmer at my company

I notice we are using a specific ansible server with an ansible user to run playbooks against our environment, and we are just starting to adopt Terraform for creating infrastructure in our cloud environment (mostly Azure with a bit of AWS). We are thinking of how we want to deploy these Terraform Modules we are building.

I had the idea to completely scrap using a VM to run off of and also not rely on something like Azure Automation runbooks (which is platform specific), but instead to create a quick Ubuntu docker container, configure the OS how we want it with scripts, do my ansible/terraform installs, authenticate myself as admin, and run my playbook/module against whatever environment (be it QA or Prod). After running the change against the environment we are going to delete the container and poof everything is gone and we dont need to manage servers. This would also allow us to pivot between cloud providers and switch to something more "microservice" related.

Is this a standard approach? I'm trying to stay away from spinning up machines to tend to and I just want to use our Git, and our local machines if possible relying on IAM and MFA for authentication.

Is there a better practice for what I'm trying to do? are there some common pitfalls I'm going to encounter when I try to explore this path? I'm trying to see if someone has thought to use this approach for my purposes before and
has some advice. Sorry in advance if the question is formulated poorly or isnt clear enough!


Edit: sorry for the caps lock title, I'm not sure how I can edit that as it would not let me enter normal caps when I created the post.

CircleCI

Hi

​

We're considering moving from Jenkins to either GitLab or Circle CI - looking at Circle CI a bit more - it feels like it is a straight replacement for Jenkins (e.g. no static code analysis, no artifactory/maven repository, no container registry etc.). Is that a fair comment?

Also, anything you'd say makes CircleCI shine above all else for Jenkins 2.0?

Seems like GitLab is heading more to be the the one-stop shop for everything.
