Web Servers

What is a Web Server?

A web server is a special computer that holds websites and delivers them to your web browser. When you enter a website's address, your browser sends a request to the web server. The server then finds the website files and sends them back so you can see the site on your screen.

How Does a Web Server Work?

Receiving Requests: When you type a URL into your browser, it sends a request to the server where the website is stored.
Finding Files: The web server looks for the right files that make up the website.
Sending Back Data: Once the server finds the files, it sends them back to your browser to display the website.

Types of Web Servers

There are different types of web servers, including:

Apache: One of the most popular web servers, known for its flexibility and wide range of features.
Nginx: Known for its speed, it is often used for high-traffic websites.
Microsoft Internet Information Services (IIS): A web server for Microsoft Windows that supports ASP.NET applications.

Why are Web Servers Important?

Web servers are crucial for the internet because they make it possible for you to access websites. Without web servers, you would not be able to browse the web or access online information. They help businesses host their websites and provide services to customers around the world.

Why Assess a Candidate’s Web Servers Skills?

Assessing a candidate's web servers skills is important for several reasons. First, web servers are the backbone of any website. They are responsible for handling requests and delivering web content to users. If a candidate understands web servers well, they can help keep a website running smoothly.

Second, companies need skilled professionals to handle web server issues. If something goes wrong, it can affect the entire business. Hiring someone who knows how to manage web servers can prevent problems and reduce downtime.

Finally, knowing about web servers is essential for anyone working in tech or web development. This skill shows that a candidate has a good understanding of how the internet works. By assessing this skill, you can ensure that you find the right person who can contribute to your team and help your business grow.

How to Assess Candidates on Web Servers

Assessing candidates on their web servers skills can be straightforward and effective. One of the best ways to evaluate these skills is through practical tests. These tests can simulate real-world scenarios where candidates must troubleshoot web server issues or configure server settings.

Another useful method is a technical quiz focused on web server fundamentals. This quiz can cover key concepts, such as server types, request handling, and common web server software like Apache or Nginx.

Using a platform like Alooba makes it easy to create and administer these assessments. With Alooba, you can customize tests to fit your business's specific needs, ensuring you find the right candidates with strong web servers skills. This approach not only streamlines the hiring process but also helps you make informed decisions based on real performance.

How Web Servers are Used

Web servers play a crucial role in delivering websites and web applications to users around the globe. Here are some key ways they are used:

1. Hosting Websites

One of the primary functions of web servers is to host websites. They store website files, including HTML documents, images, and scripts, making them accessible to anyone with an internet connection. When a user types a URL into their browser, the web server processes the request and sends the requested files back.

2. Serving Dynamic Content

Web servers are also used to serve dynamic content. This means they can generate web pages in real-time based on user interactions or data from databases. For example, when you log into a social media site, the web server retrieves your specific data and presents it in a personalized view.

3. Handling User Requests

Web servers manage user requests efficiently. They handle multiple requests at the same time, ensuring that each visitor receives the content they need without delay. This is essential for high-traffic websites that experience thousands of requests per second.

4. Supporting Web Applications

Web servers are integral to running web applications. They allow software to run on remote servers while users interact with it through their web browsers. This setup offers flexibility, as users can access applications from any device with an internet connection.

5. Providing Security and Reliability

Web servers implement security measures, such as SSL certificates, to ensure safe data transfer between users and the server. They also provide reliability through practices like load balancing and redundancy, ensuring that websites remain accessible even during high traffic or server failures.

In summary, web servers are essential for hosting websites, managing user requests, serving dynamic content, supporting web applications, and providing security. Understanding how web servers are used is vital for businesses looking to optimize their online presence and improve user experience.

Roles Requiring Good Web Servers Skills

Several roles in the tech industry require strong web servers skills. Here are a few key positions:

1. Web Developer

Web Developers are responsible for building and maintaining websites. A solid understanding of web servers is essential for ensuring that web applications function correctly and efficiently.

2. System Administrator

System Administrators manage and maintain server environments. Their role often involves configuring web servers, monitoring performance, and implementing security measures to protect data.

3. DevOps Engineer

DevOps Engineers bridge the gap between development and operations. They need good web servers skills to automate deployment processes, optimize server performance, and ensure seamless integration of web applications.

4. Technical Support Specialist

Technical Support Specialists provide assistance with web-related issues. Having sturdy web servers skills helps them quickly resolve server-related problems and offer effective solutions to users.

5. Network Engineer

Network Engineers design and manage network infrastructures. A good understanding of web servers is crucial for them to ensure reliable communication between servers and clients.

Our Customers Say

I was at WooliesX (Woolworths) and we used Alooba and it was a highly positive experience. We had a large number of candidates. At WooliesX, previously we were quite dependent on the designed test from the team leads. That was quite a manual process. We realised it would take too much time from us. The time saving is great. Even spending 15 minutes per candidate with a manual test would be huge - hours per week, but with Alooba we just see the numbers immediately.

Shen Liu, Logickube (Principal at Logickube)

We get a high flow of applicants, which leads to potentially longer lead times, causing delays in the pipelines which can lead to missing out on good candidates. Alooba supports both speed and quality. The speed to return to candidates gives us a competitive advantage. Alooba provides a higher level of confidence in the people coming through the pipeline with less time spent interviewing unqualified candidates.

Scott Crowe, Canva (Lead Recruiter - Data)

How can you accurately assess somebody's technical skills, like the same way across the board, right? We had devised a Tableau-based assessment. So it wasn't like a past/fail. It was kind of like, hey, what do they send us? Did they understand the data or the values that they're showing accurate? Where we'd say, hey, here's the credentials to access the data set. And it just wasn't really a scalable way to assess technical - just administering it, all of it was manual, but the whole process sucked!

Cole Brickley, Avicado (Director Data Science & Business Intelligence)

I wouldn't dream of hiring somebody in a technical role without doing that technical assessment because the number of times where I've had candidates either on paper on the CV, say, I'm a SQL expert or in an interview, saying, I'm brilliant at Excel, I'm brilliant at this. And you actually put them in front of a computer, say, do this task. And some people really struggle. So you have to have that technical assessment.
