Monolithic VS Microservices Architecture

In the realm of software architecture, the choice between Monolithic and Microservices can shape the destiny of your application. Let's break down the key differences in a nutshell! 🧩

1. Monolithic Architecture 🏰

- One Big Castle: Monoliths are like a majestic castle, where all components (database, server, user interface) are tightly knit into a single structure.

- Unified & Simple: Easy to develop and deploy due to its unified structure. Changes are made in one place, making coordination a breeze.

- Scaling Challenges: Scaling can be a challenge. When one aspect needs upgrading, the entire application must be scaled, even if only a small part requires more resources.

2. Microservices Architecture 🌐

- City of Specialized Buildings: Microservices resemble a bustling city, with each service as a specialized building handling a distinct function.

- Scalability & Flexibility: Offers scalability on a per-service basis. If one part of the application needs more resources, you can scale just that service.

- Increased Complexity: As the number of services grows, managing the communication between them can become complex. Decentralization brings its own set of challenges.

👨‍🎓Awesome Learning👨‍🎓

А curated lists of awesome learning resources for a Software Test Automation Engineer

I have been into Software Testing role since last 14+ years, however I must tell you that my most of the time was spent in manual testing the applications. When I got into this role, specifically it was the time when there used to be a lot of desktop applications. I started my career in 2008, being a Commerce graduate and not knowing the basic alphabets of engineering, initially it was very difficult to understand what programming, testing, releases was all about! Thanks to all my mentors and guides, they helped me a lot to understand those basic concepts about testing and how the actual process works.

I have been asked by many about my career transformation journey from Manual Testing to a Test Automation Engineer, hence I thought of creating this repository which has the learning path I followed to become a Test Automation Engineer.

Ever wondered how your computer securely communicates with a remote server? 🤔

Let's dive into the magic behind SSH and unravel its secrets. 🔍💻

1. What is SSH? 🤷‍♂️
SSH, or Secure Shell, is a cryptographic network protocol that enables secure communication between two devices over an unsecured network. It's like a secure tunnel for your data! 🚇🔒

2. Key Players: Public and Private Keys 🗝
SSH uses a pair of cryptographic keys – a public key (shared with the world) and a private key (kept super-secret). 🤫 When you connect, these keys perform a digital handshake to ensure a secure connection. 🤝🔑

3. The Handshake Dance: Authentication 💃
The handshake involves your computer proving its identity using the private key, and the server verifying it using the corresponding public key. Think of it as a secret password exchange, but way cooler! 😎🕵️

4. Encryption Enchantment: Securing the Chat 🛡
Once the handshake is complete, SSH wraps your data in layers of encryption, ensuring that even if someone intercepts it, they'll find nothing but gibberish. 🤐📡

5. Port Perfection: Default Port 22 🚪
SSH communicates through port 22 by default. It's like the entrance to your secure data party! 🎉🚪 But beware, changing ports adds an extra layer of security. 🕵️‍♀️🔐

SSH is the superhero of secure communication, ensuring your data remains confidential, and the connection is trustworthy. 🦸‍♂️💼 Next time you SSH, remember the cryptographic dance happening in the background, making it all possible! 🕺🌐

💻 Lenovo unveils transparent laptop concept 💻

Lenovo showcased a transparent laptop concept at the recent Mobile World Congress (MWC) in Barcelona. This concept device, which has attracted significant attention, features a transparent display panel and a detachable, transparent keyboard.

The transparent display functions by overlaying graphics on the user's surroundings, effectively creating a form of augmented reality. While aesthetically pleasing and embodying futuristic design elements, the device's practical applications remain unclear.

Challenges and Considerations:

Limited Use Cases: The transparent display offers minimal benefit in typical laptop usage scenarios, where users often face walls or windows.
Sunlight Readability
Privacy Concerns: The rear of the device reflects the display, potentially revealing information viewed by the user.
Keyboard Functionality: The capacitive touch keyboard likely cannot compete with the feel and tactility of traditional keyboards.

Key Browser Statistics: Picking Test-Worthy Browsers in 2024 💻🌐

Customer satisfaction is crucial for the success of your business, еspеcially when you are in thе highly compеtitivе digital world. And this competition will only continue to rise. Therefore, to outshinе your competitors, it’s crucial to dеvеlop mind-blowing wеb applications for your softwarе products.

Whether it’s revamping an еxisting wеbsitе or building it from scratch, it’s important to еnsurе it dеlivеrs a uniform еxpеriеncе across various browsеrs and opеrating systеms. Howеvеr, browsеrs display wеbsitеs diffеrеntly due to varying browser engines. So, how can you dеtеrminе if your wеb app is compatiblе with multiple browsеrs? By conducting cross browsеr compatibility tеsting. This tеsting еnsurеs that your wеbsitе works sеamlеssly on both latest and legacy browsеrs.

CI/CD Systems - Information Software tester must know👨‍🎓📚

Continuous Integration/Continuous Deployment (CI/CD) systems revolutionize software development by automating the process of code integration, testing, and deployment. CI ensures that code changes are regularly merged into a shared repository, promoting collaboration and early detection of errors. CD extends this pipeline to automatically deploy code to production environments, minimizing manual intervention and reducing deployment risks.

CI/CD systems enhance development speed, quality, and reliability. Automated testing within the pipeline ensures that new code meets predefined standards and does not introduce regressions. This leads to faster feedback loops, enabling developers to address issues promptly. By automating repetitive tasks, developers can focus on innovation and code improvement rather than spending time on manual integration and deployment processes.

𝗚𝗶𝘁 𝗠𝗲𝗿𝗴𝗲 𝘃𝘀 𝗥𝗲𝗯𝗮𝘀𝗲

One of the most powerful Git features is branching. Yet, while working with it, we must integrate changes from one branch into another. The way how to do this can be different.

We have two ways to do it:

𝟭. 𝗠𝗲𝗿𝗴𝗲

When you merge Branch A into Branch B (with 𝚐𝚒𝚝 𝚖𝚎𝚛𝚐𝚎), Git creates a new merge commit. This commit has two parents, one from each branch, symbolizing the confluence of histories. It's a non-destructive operation, preserving the exact history of your project, warts, and all. Merges are particularly useful in collaborative environments where maintaining the integrity and chronological order of changes is essential. Yet, merge commits can clutter the history, making it harder to follow specific lines of development.

𝟮. 𝗥𝗲𝗯𝗮𝘀𝗲

When you rebase Branch A onto Branch B (with 𝚐𝚒𝚝 𝚛𝚎𝚋𝚊𝚜𝚎), you're essentially saying, "Let's pretend these changes from Branch A were made on top of the latest changes in Branch B." Rebase rewrites the project history by creating new commits for each commit in the original branch. This results in a much cleaner, straight-line history. Yet, it could be problematic if multiple people work on the same branch, as rebasing rewrites history, which can be challenging if others have pulled or pushed the original branch.

So, when to use them:

🔹 𝗨𝘀𝗲 𝗺𝗲𝗿𝗴𝗶𝗻𝗴 𝘁𝗼 𝗽𝗿𝗲𝘀𝗲𝗿𝘃𝗲 𝘁𝗵𝗲 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲 𝗵𝗶𝘀𝘁𝗼𝗿𝘆, especially on shared branches or for collaborative work. It's ideal for feature branches to merge into a main or develop branch.

🔹 𝗨𝘀𝗲 𝗿𝗲𝗯𝗮𝘀𝗶𝗻𝗴 𝗳𝗼𝗿 𝗽𝗲𝗿𝘀𝗼𝗻𝗮𝗹 𝗯𝗿𝗮𝗻𝗰𝗵𝗲𝘀 or when you want a clean, linear history for easier tracking of changes. Remember to rebase locally and avoid pushing rebased branches to shared repositories. Also, be aware 𝗻𝗼𝘁 𝘁𝗼 𝗿𝗲𝗯𝗮𝘀𝗲 𝗽𝘂𝗯𝗹𝗶𝗰 𝗵𝗶𝘀𝘁𝗼𝗿𝘆. If your branch is shared with others, rebasing can rewrite history in a way that is disruptive and confusing to your collaborators.
