For some good reasons I haven't been posting my DevOps journey here.

My Azure DevOps AZ 400 exam, also putting some crafts on Cloud native using AWS and KodeKloud has been taking my time.
Meanwhile, I have covered few DevOps tools in the past few weeks.

#K8s components (deployment, Services, Ingress, Secret, volume and much more...)
#Jenkins
#GitOps
#Vagrant
#Docker deep dive
#Terraform
#Bash scripting
#Selenium (looking for alternative)
#Helm Charts
#Lens
And more...

@PearsonVUE decided to disrupt my exam without consideration, I'm hoping that @MicrosoftLearn will resolve this asap.

The journey has been awesome tho.

I'll share my experience very soon.

Most CS undergrads go through four years without learning how to prepare for jobs in #Cloud Dev firms.

They learn OS, DBs, languages like #Javascript, #C++, #python, etc. but little on Cloud-related topics.

Colleges/Universities should consider incorporating these 10 topics.👇

1.History and evolution of Distributed Computing to Cloud computing
-#Grid computing
-#Parallel computing
-#Cluster computing
-Utility computing
-#Virtualization
-Service orientation
while talking about performance, robustness, high availability, delivering SLAs

2. Why Cloud Apps?
- Types of Cloud (Public, Private, VPC, Hybrid, Multi-Cloud)
- Types of offerings (IaaS, PaaS, SaaS)
- Service level objectives (SLOs) and Service Level Agreements (SLAs)
- Regulatory issues, Sovereign Clouds, Cloud Security

Microservices are tough to learn.

Not only do you have to learn deep and complicated tools. You must also learn to build a distributed application. This requires new design patterns, protocols and methods of communication. That’s a lot to learn!

The learning curve we must endure can seem insurmountable if you tackle it by yourself, but instead, we’ll take on this development adventure together.

@apachekafka

🧵 If you run @apachekafka in production, creating clusters, topics, connectors etc. by hand is tedious and error-prone. Better rely on declarative configuration which you put into revision control and apply in an automated way, #GitOps-style. Some tools which help with that:

@purbon

1⃣ JulieOps (github.com/kafka-ops/julie) by @purbon, which helps you to "automate the management of your things within Apache Kafka, from Topics, Configuration to Metadata but as well Access Control, Schemas". A nice intro in this post by Bruno Costa: medium.com/marionete/how-…

@segment

2⃣ topicctl (github.com/segmentio/topi…) by @segment: "Easy, declarative management of Kafka topics. Includes the ability to 'apply' topic changes from YAML as well as a repl for interactive exploration of brokers, topics, consumer groups, messages, and more"

🤠 GCP(Google cloud platform)

1️⃣ Terraform with Google Cloud: lnkd.in/gBuZ-nh6

2️⃣ Terraformer: A CLI tool that generates tf/json and tfstate files based on existing infrastructure (reverse Terraform). Very good and useful: lnkd.in/gibKk4U

3️⃣ FREE course at coit.io to build a FULLY automated infrastructure in the AWS Cloud using GitHub, Jenkins, Terraform, and Ansible. Link to the Course is => lnkd.in/gD97mjtS

This is advanced program, and you should know the basics of Terraform and Ansible.

✨A thread on joining lending/borrowing protocol on @BastionProtocol

1/18
For example, #NEAR has an LTV of 60%, $USDC 85%, $USDT 80%, $ETH 70%. Other assets are also the same but they will have a different LTV (Loan-to-value).

#BMEanalytics $NEAR $BSTN #auroraisnear #DeFi $USN

@auroraisnear

2/18
Keep in mind that LTV is not the profit that you can earn but it is the percentage that you can borrow based on the assets that you have deposited in the Lending platform.

#BMEanalytics $NEAR $BSTN @auroraisnear #DeFi $USN @BastionProtocol

@finance_ref

3/18
First, you need to buy $NEAR on any exchanges and withdraw them into your #NEAR Wallet. Since #Aurora EVM uses $ETH as transaction fees so connect your wallet to @finance_ref and swap a few Near to ETH.

What is CI/CD?

Continuous integration (CI) and continuous delivery (CD) are two approaches to software development that are designed to improve code quality and enable rapid delivery and deployment of code.

#DevOps #CICD #Cloud #Agile #Testing #Cloud #Linux #Security #ITjobs

A modern CI/CD pipeline in DevOps has build, test, and deploy stages-and aims to automate as many of the processes within these stages as possible.

1. Source Code: Changes to source code can trigger CI/CD tools to initiate the pipeline, or the CI/CD pipeline may be triggered

by automated scheduled work sessions or user-initiated workflows.
2. Build: The new code changes to applications are created and compiled to be prepared for the testing phase.

3. Testing: Testing automation via CI can save developers tremendous time and effort.

Navigating the cloud and #DevOps horizon is hard, things are moving quickly.

ThoughtWorks recommends HOLD on handwritten AWS CloudFormation in #TechRadar 2019 edition. Building a complex infrastructure in essentially huge YAML text file is doomed to fail thoughtworks.com/radar/tools/ha…

@thoughtworks

You could thought that Templating in YAML is a solution here, but it's also on HOLD in #TechRadar 2019 by @thoughtworks thoughtworks.com/radar/techniqu…

The same about templating in JSON, because YAML is JSON actually. Better to use real programming language instead. The dev in #DevOps

So Terraform is the ADOPT in #TechRadar 2019 and "sensible default" that addresses the shortfalls of AWS CloudFormation as stated here:
thoughtworks.com/radar/tools/ha…

There are other options listed, including troposphere, sceptre, Stack Deployment Tool and Pulumi. Not sure if endorsed.

Hoy me gustaría compartir algunas reflexiones fruto de las últimas novedades aparecidas y mis experiencias en cliente con #infrastructureascode en #AWS. Vamos al lío 👇

Siempre me he sentido más atraido hacia el enfoque declarativo por su falsa sensación de control y orden, pero con configuraciones grandes, poder refactorizar el código hacia abstracciones propias y modificar su definición/parametrización con código ha sido determinante

En ese sentido, #cloudformation como tal siempre me ha parecido muy locura y un formato más de bajo nivel que otra cosa. En general siempre trabajo con herramientas que lo generan como #serverlessframework o #amplify

On the Tagging options for #OCI

Tagging is the act of putting labels on objects. There is 1:n relation, meaning one object can have many labels applied to it.

Traditional systems that implement tags are usually backed with a “set” data structure: an unordered/unindexed collection. The key is the value. E.g: `Prod, Dev, CC127638, Finance`

@HashiCorp

So I actually want to talk about this. Let's talk about what we (@HashiCorp and @GCPcloud) accomplished in 2019 with the Terraform provider for Google Cloud Platform.

https://twitter.com/paddycarver/status/1207085028636688384

As a reminder, all of these accomplishments are thanks to the hard work of a number of people, working across HashiCorp and Google Cloud Platform, to bring our users the best experience we can. They deserve all the credit here. I'm just the guy running his mouth.

I'm also not going to be covering the personal life stuff that happened in 2019, not because it didn't impact our work--it did, significantly--but because it is personal.

@tasdikrahman

Trunk-based development for #terraform infra makes a lot more sense, my observations after moving from a branch based model, being. Half applied/stale infra changes will not be the case anymore as compared to when multiple branches being are in active development (1/n)

As for when trying to avoid conflicts for locking states and avoiding multiple people trying to modify the same state, putting #terraform plans and applies on CI would immediately take away the need of a tool like #atlantis. (2/n)

Maintaining #terraform modules for repeated infra objects can be used as plug and play should ideally be versioned, and specific versions be used by teams. Having all of this on CI takes away the burden from ops folks of manually applying it, which reduces margin of error(3/3)

@HashiCorp

A common pattern that emerges when using @HashiCorp #Terraform is to have many types of policies inlined using a heredoc. This is frustrating as it means you can't use standard tools to validate and/or format these JSON policies.

gist.github.com/nhandler/97f55… is my attempt at a solution to this problem. All of your policies get defined as standalone JSON files within a templates/ directory. This makes it easy to copy from other tools (or even web consoles) and validate/format the contents.

A template_file is used to facilitate the use of variables, which are a great way to avoid ending up with magic numbers or hardcoded values in your policies. And a list of filenames is used to avoid having to declare multiple template_files and duplicate the list of variables.
