Explain these key concepts (Beginner Cloud DevOps Program )
Published: 2024-05-10 22:38:55

1.  What is Virtualization?
Virtualization in computing is the process of simulating hardware and software in a virtual (software) environment such as computers, operating systems, storage, and network. And it does it in a virtual or software environment.

2. Scalability
Scalability is a major advantage of cloud computing. The term "cloud scalability" describes a cloud computing infrastructure's capacity to dynamically modify resources in response to changing demand. This implies that you won't need to spend a lot of money on expensive hardware upgrades or infrastructure modifications as your company expands because your cloud environment can easily adjust to give more processing power, storage, or bandwidth.

3. Agility
This refers to a cloud customer’s ability to develop, test and launch an application speedily using cloud resources. Agility makes it possible to respond to critical business situations and goals quickly.

4. High Availability
In cloud computing, high availability (HA) refers to designing a system that remains operational and accessible for extended periods, even during hardware or software failures. It's about ensuring minimal downtime for your applications and services.

5. Fault Tolerant
Fault tolerance in cloud computing is all about building systems that can withstand unexpected glitches and outages, ensuring your applications keep running with minimal disruption. It's like having a backup plan for your virtual infrastructure.

6. Global Reach
Azure has more data centers regions than any other cloud provider. This means that businesses can start from anywhere in the world, and if they want customers in any other part, they need to save the data for that business in an Azure Region closest to the customers.

7. What is the difference between Elasticity and Scalability
Both elasticity and scalability are important concepts in cloud computing that deal with handling changes in demand, but they approach it in different ways:

 Elasticity: Elasticity in cloud computing is the system’s 
 capacity to automatically adjust resources like processing 
 power, storage, and network capacity in response to changing 
 workloads, enabling dynamic scaling based on demand.

 Scalability: The term scalability refers to a system’s 
 capacity to meet an ever-increasing demand on an expected or 
 unforeseen workload by adding resources manually or 
 automatically to fulfill the added task. In Azure, we can 
 scale out to ensure capacity when there is a peak period and 
 return to normal when the peak drops.

![Aggressive Optimization](https://miro.medium.com/v2/resize:fit:1400/format:webp/1*MZWyyfn2uVsXG8owuUSl6Q.png)
If you're not using analytics to maximize user acquisition, engagement, and technical performance, your progress is haphazard. Web analytics aren't just data points that peak interest without inspiring action; they must drive intentional product improvements in each SDLC iteration. The focus is not only on expanding your featureset but also on aggressively optimizing your product, because continually introducing new features without strengthening implemented ones just constructs a house of cards. Define meaningful KPIs, establish benchmarks, and schedule regular analyses. Use insights from each change to prescribe change in the next iteration. Treating analytics as essential to iterative and aggressive optimization ensures your web applications are robust and aligned with maximal business success.

DNS and Other Taxes

# Tl;dr

![This is probably what you're looking for](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/t3tb20jq5lphuqiwphmg.png)

## Setup Your Domain URLs
The most common web address setup has the **apex** and **`www` subdomain** go to the same website (i.e. respectively `https://example.com` and `https://www.example.com` both work). Two types of DNS records are used to connect the apex to the site's source/hosting and to point the subdomain at the apex.

1. Most cloud hosts provide a unique subdomain like `krabby-kitten-1234.the-cloud.com`. Create an **ALIAS Record** with host `@` and value of the cloud subdomain.
  * If you have an IP address instead, create an **A Record** with it ![If you have an IP instead](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/iwm11hxm1ivrjwhby592.png)
  * Some DNS Providers (e.g. Cloudflare) use CNAME flattening to do this
2. Create a **CNAME Record** with host `www` and and apex domain, `example.com`, as the value.

Finally, register the apex and subdomains with your cloud provider. This is typically a part of generating SSL certificates.

Hopefully that’s all you need! The rest of this post serves as an appendix if I get amnesia or if this is the first time you’re encountering these terms.

### Why?

I call infrequent intricate tasks with painful penalties for minuscule mistakes “doing your taxes.” They’re bad enough without unambiguous concise information being so difficult to find. As to "be the change you wish to see in the world," this is the Good Enough™ primer for the next time.

# Appendix

## Parts of a URL
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ko37feas9b1qtivffnfp.png)

## Record Types

- A Record
  - This connects either an **apex** or **subdomain** to a static IP address.
- CNAME Record
  - This connects a **subdomain** to another URL such as `krabby-kitten-1234.the-cloud.com`. It cannot be used for the apex domain because … reasons.
- ALIAS Record
  - A CNAME that _can_ be used for the **apex** or **subdomains** 😑

## DNSWTF
Ultimately a URL needs to be turned into an IP address and it’s the Domain Name System (DNS) that handles this. When you buy a domain from a registrar, you create DNS records to tell other computers what IP address they can connect to in order to access the root and subdomains. When you specify another URL like with ALIAS and CNAME records, that address DNS records are looked up and so on until an IP address is found.

Como rodar um servidor NodeJS em um smartphone Android
Tags: android, termux, node, javascript
Published: 2024-05-10 20:40:35

Rodar um servidor Node.js em um celular Android pode parecer uma tarefa incomum, mas é surpreendentemente simples, graças ao [Termux](https://termux.dev/en/), um emulador _open-source_ de terminal para Android. Com o Termux, você pode instalar e executar o Node.js, bem como outros pacotes e bibliotecas, permitindo que você desenvolva e teste aplicativos directamente no seu dispositivo móvel.

## Pré-requisitos:

- Um celular Android _(No meu caso um Samsung Galaxy S21+)_
- O aplicativo Termux instalado ([Download a partir do FDroid](https://f-droid.org/en/packages/com.termux/)) _Para instalar o termux é necessário permitir a instalação de aplicações de fora da Play Store no seu dispositivo_


## Passo 1: Instalar o Node.js

1. Abra o Termux e actualize os pacotes:

```bash
pkg update && pkg upgrade
```

2. Instale o Node.js:

```bash
pkg install nodejs
```
3. Verifique a versão do Node.js para confirmar a instalação:

```bash
node -v
```

## Passo 2: Criar um Servidor Simples

1. Crie um directório para o seu projecto:

```bash
mkdir node-server
cd node-server
```
2. Crie um arquivo JavaScript chamado server.js e adicione o seguinte código:

```javascript
const http = require('http');

const hostname = 'localhost';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello from Node.js on Android!\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}`);
});

```

 3. Execute o servidor:

```bash
node server.js
```

## Passo 3: Acessar o Servidor

1. Abra um navegador no seu dispositivo Android, acesse o seguinte URL:
`http://localhost:3000`

Voila! Você deve ver a mensagem "Hello from Node.js on Android!" na tela.

## Considerações finais
Ao usar o Termux nos smartphones Android tu desbloqueias imensas possibilidades que normalmente iriam requerer muitos recursos ou esforço, como, por exemplo, usando o [termux-api](https://wiki.termux.com/wiki/Termux:API), tens o acesso aos recursos do smartphone (Câmara, SMS, Interface de redes, etc.) o que pode te permitir desenvolver projectos que usam desses recursos a custo baixo e com facilidade no desenvolvimento.

Functional and Non-functional testing
Published: 2024-05-10 20:20:50

Functional testing:
Functional testing is a software testing done by both Manual and Automation to make sure the software meets the Software required document and business requirements from the customer. According to the client needs, we focus on preparing the test cases including both positive and negative cases, so that the software guarantees the clients by covering all the test cases from the start to end.
Non- functional testing:
Non-functional testing is a software testing also done by both manual and automation team to mostly check the throughput and sensitivity of how the software is performing after making sure the functionality of the software such as reliability, performance and usability. Even the OS upgrade comes under non-functional testing.
Types of functional testing:
Unit testing: Unit testing is a testing where when the developer starts to develop a new feature, they write a test case and start testing the feature to make sure it works as expected from the software requirement document.
Integration testing: Integration testing is a testing where when software is getting built, the multiple features are tested to make sure whether it’s working as expected when they are integrated.
Regression testing: Regression testing is a testing which will be done when there is a small change or any code change kicked in to make sure it doesn’t affect the software. So, when doing regression testing, the existing features should work as expected as it’s untouched.
Sanity testing: Sanity testing is a testing which is also a sub-set of regression testing which will be done once they upgrade it after all the code changes kicked in. So once the final version is available, testers do sanity testing to make sure the software works as expected.
Smoke testing: Smoke testing is a testing which done to verify the build is working as expected. 
User acceptance testing: User acceptance testing is a testing done in the end as sanity testing before releasing the software.
System testing: System testing is a testing which includes both hardware and software where when the final version of the software is released and it will be done end to end testing.
Performance testing: It comes under non-functional testing where it makes sure about reliability and performance where when we load too many jobs, it doesn’t get crash or it works as expected to meet the requirements given by systems or developer. 
Stress testing: Stress testing is a testing where the tester can load as many as jobs needed to check if the software can handle the jobs without crash and passes without any issues. So basically, it just checks and validates what’s the correct behavior when we load heavy jobs in the software.
Load testing: Load testing is a testing which will be done by the multiple users at a same time to validate the robustness and performance of the software.
In short, Functional testing is more focused on business requirement and non-functional testing is more focused on performance of the software.

## The Sad Status Quo

Many of the DevSecOps vendors suffer from a mix or all of the following ailments, 

1. They won't let you fully use your existing best-of-breed tools. 
2. They offer no support for integrations or limited opportunities to integrate. 
3. They make it hard to customize projects at scale. 
4. They’re deliberately challenging when it comes time to integrate any legacy system. 
5. They leave you with recurring integration issues when they oblige and integrate. 
6. They don’t adopt internal company processes effectively. 
 

And the list grows…
