What is Web Application Architecture? Components, Layers, and Types

Web application architecture forms the foundation for creating dynamic and interactive websites and web applications. It’s like the blueprint that guides developers in building robust and efficient systems.

But what exactly are the components and layers that makeup web application architecture? And what are the different types of web application architectures out there? We’ll find out all of that and more, breaking it down in a cool and conversational style, so you can easily grasp these tech concepts and level up your understanding. Let’s get started!

What is Web Application Architecture?
Web application architecture is the structure and framework that defines how different components of a web application interact with each other to deliver the desired functionality. It encompasses the relationship between client-side and server-side code, the flow of data, and the overall system design. In essence, web application architecture determines how a web application handles user requests, processes data, and presents information to the user.

The Difference Between Websites and Web Applications

Before we dive deeper into web application architecture, it’s important to distinguish between websites and web applications. Traditionally, websites were composed of static pages that provided information to visitors. On the other hand, web applications are more interactive and dynamic, offering users the ability to perform tasks such as submitting forms, making transactions, and accessing personalized content. Web applications combine both static and dynamic elements to create a more engaging and interactive user experience.

Understanding Web Application Architecture Components
Web application architecture is composed of various components that work together to deliver a seamless user experience. Let’s explore the key components in more detail:

User Interface App Components:
User interface components handle the visual presentation and user interaction aspects of a web app, such as display, dashboards, notifications, and settings. These elements contribute to a user-friendly experience but are distinct from the app’s core functionality.

Structural Components:
Structural components are the foundation of a web app’s functionality:

Web Browser or Client:** Users access web apps via browsers, enabling interaction and rendering front-end components.
Web App Server: Processes requests, executes logic, and generates responses. It acts as a link between browsers and databases.
Database Server: Stores and manages persistent data. It ensures secure and efficient data storage and retrieval.
Web Application Three-Tier Architecture Layers

Web application architecture is often organized into three tiers or layers: the presentation layer, the business layer, and the persistence layer. Let’s explore each layer in more detail:

Presentation Layer: The user-facing part accessed via browsers. It includes UI components (HTML, CSS, JavaScript) defining the app’s look, and UI process components managing user interactions.
Business Layer: Also called business logic, it processes user requests, enforces rules, and controls the data flow. It ensures the app functions as intended, handling input, data processing, and response generation.
Persistence Layer: Handles data storage and retrieval. Interacts with databases to securely store and retrieve data for the app. Ensures efficient data access and plays a role in app performance and reliability.
Types of Web Application Architecture
Web application architecture can be categorized into different types based on the distribution of application logic between the client and server sides. Let’s explore the three primary types:

Single-Page Apps (SPAs): SPAs update content without reloading pages by using AJAX for smooth, dynamic interactions.
Microservices: This breaks apps into small, independent services communicating via APIs, allowing flexible tech choices and faster development.
Serverless Architectures: Third-party cloud services handle server management, enabling focused coding and scalable apps.

Career Success Factors: 5 Simple Ways for a Career Boost

There are many career success factors. A combination of these various factors at the right time can be potent for your career boost.

It’s always tough to give advice on career success factors because there isn’t really a set of formula you can follow that can guarantee career success. A combination of various factors in the right context and with the right character will give your career a boost.

For senior executives, these 5 career success factors will probably work more as a reminder. For career newbies,especially if you are in your first year of work – these factors will be your guide to a career boost. Like all career advice I give, do not expect instant results. Practiced often and you will see the results.

1. NOW!Do things NOW! Do not procrastinate. Nothing irks a manager more than a newbie at work that is already showing signs of lazing or taking short cuts. Attack your work immediately. Have a plan of attack to the work that is assigned to you.

Without procrastinating you can finish your work much earlier. This allows you to be assigned more work. As the trust with your supervisor increases, he/she will assign you more and more important work. Make a decision now to put in place a plan for this career success factor.

2. Next StepsNever leave a meeting without clear next steps that you are required to complete. A date of when the work is expected to be completed by you is part of this next step. This also applies to your discussion with your supervisor. Always seek to clarify what’s needed from your end before you leave the discussion.

If you are lucky enough to be chairing any meetings or are a project leader, remember that listing the set of next steps or action plan is your responsibility. When you have clear next steps; who and when the task should be completed, you become productive. You get a career boost when you are productive. It is one of the easiest career success factors to practice.

3. NoticeNo, I do not mean giving notice. Notice here means being a keen observer of things around you and people. Now, it doesn’t mean being nosy and to start gossiping. Every office has their dynamics. Do not be pulled into the politics that can hurt your career at an early stage. Notice here means to observe and to take note of things. When you notice things you become more careful. You also become better at knowing how things work in the office. You will blend in better. Notice and learn what are the norms of the industry, the ethics and the legalities. Notice the corporate culture and who is in charge. Sometimes those truly in power are those who can influence the bosses.

4. NiceAmongst all the career success factors, this is probably one that is the easiest to do. Being nice doesn’t mean you go around volunteering to make coffee for your colleagues. It can mean very simple and sincere greetings of “Good Morning.” It can also be a pleasant smile. You need to be mindful to do this in order to transfer it to your colleagues. Ever noticed some people smile and greet for the sake of doing it? You can’t really feel that they mean it? All else being equal, being genuinely sincere and nice can give you a career boost.

One sub point I would add to this is to be neat. This means being organized, clean and orderly. As a freshie with these efficient behaviors, you become nice to work with, as you are productive.

5. NetworkSure, you are new to the industry. There are very few people you know. But that should not stop you from finding out where people hang out and when. Start with your colleagues first. Where do they go for lunch?

To network at a smaller scale is to get your face recognized. Then you can work on getting your name known. There is a caveat to this, while networking is one of the important career success factors – make sure you deliver good work. All the networking cannot give you a career boost if you do not deliver good work.

These career success factors work well for career newbies and can give you a career boost. But remember to seek to do great work first before thinking about how you can boost your career.

Achieving Career Success With Inter-personal Skills

Dandee Cleofas has managed restaurants all over the world. From his home in the Philippines to the Middle East, Alberta and now Toronto, he has worked in the food-service industry for the last 20 years. Cleofas’ experience in customer service has taught him that people skills are paramount to succeeding in today’s workforce.

“After 20 years of work, I’m very familiar to hospitality and the restaurant industry, but in different countries there are different approaches,” he said, referring to the communications styles that vary from country to country.

So, after arriving in Canada, he turned to Evergreen College-a Toronto-area career college-to enhance his employability. During two academic years of study, he honed his communications skills to help him in his career-one that is driven by social interactions.

This September, Cleofas graduated from that college’s Hospitality Management diploma program with a new-found understanding of his industry’s most in-demand skills.

“The most important skills I learned are about how to approach different people in various situations during operations,” he said. “There are certain dynamics and flows of operations that you need to handle.”

He is now a restaurant manager with one of the world’s largest fast food chains. He began working for this chain in entry-level positions, and then advanced to the role of team leader. Upon graduating from the college, Cleofas was promoted to a managerial role.

He says a lot of what he learned at college is directly applicable to his work.

“The college taught us the leadership skills that are important to being a manager,” he said. “We always need to motivate our employees, give positive feedback to our team, give them opportunities, recognize their developments. These are modern people skills.”

While he was up-to-date on the technical skills required in his line of work, Cleofas admits that the academic side of the restaurant industry was new to him.

“I learned more about time scheduling, employee training, how to handle people and how to manage a team,” he said. “The academic side is now helping me to achieve additional career goals.”

When asked if he would recommend a college education to future hospitality workers, Cleofas was quick to say yes.

“A career-focused college program is needed in the hospitality business. It teaches students the very in-demand people skills.”

Fellow graduate Mona Najudjaja could not agree more. As a graduate of the same hospitality program, she is applying the communication skills she learned to her career in the hotel industry. Similar to restaurants, Najudjaja says that inter-personal skills are crucial to working in a hotel’s customer-focused environment.

“The college taught me that working in the hospitality industry means dealing with a lot of people,” she says. “This means you have to talk a lot and talk nicely all of the time.”

Upon graduation, she was hired in a front-desk, customer-service role for a large hotel chain in Barrie, Ont.

“All of the material that I got from my teachers is a perfect fit for my career,” she says. “I feel so grateful, I feel so proud of myself because from this program, now I can get a job in hospitality management, which is the perfect match for my major of study.”

Prior to obtaining her college degree, Najudjaja admits that her people skills were not up to par.

“Before college, I was not really confident to talk with people,” she says. “Even if you are involved in a bad situation, you have to keep smiling. That’s what I learned.”

To enhance her career readiness, Najudjaja says her education also prepared her with the inter-personal skills required to market herself. Her college instructors offered career services to students to help them hone their interviewing and networking skills, and successfully market themselves into a new career.

Alyssa Cranston is able to showcase her people skills in the workplace on a daily basis. As a fellow graduate of the Toronto career college, she works in a daycare with special needs children.

Cranston graduated as a development service worker (DSW) who specializes in attending to children that have autism and other developmental challenges. Inter-personal skills have been critical to her career success.

“In college, I learned how to interact with children, especially those with special needs,” she says. “I learned to use a calm voice and a positive voice.”

In one and a half years of academic study, she learned both the theoretical and relationship skills required to assist clients of all ages who have developmental disabilities.

Upon graduation, Cranston was hired in a Toronto-area daycare where’s she has jump-started her career as a DSW. She attributes her success to the skills she learned during her studies, including those that enhanced her employability.

“The college and its instructors were always eager to help us in any way they could,” she says. “They helped us to fix our resumes and prepare for interviews. Then, when it was time for the real thing we were ready because we had rehearsed.”

Viviancyl Vale also works with children on a daily basis. As a graduate from the same career college, Vale studied to obtain certification as an early childcare assistant (ECA).

She says her studies encouraged her to heighten her communication skills, especially those that are critical to interacting with young children.

Originally, Vale was not planning on obtaining a post-secondary career. She accompanied a friend who was visiting the college, and it piqued her interest. She says the college staff encouraged her to try completing an admissions test for the ECA program.

After just one year of academic study, Vale is glad that she took the initiative to jump-start her career.

“The best part about my studies is that they gave me a challenge,” she says. “We had fun in our classes. It was never boring.”

Upon graduation, Vale was hired to work as an ECA in a Toronto daycare, the same one where she completed her academic placement. In this role, she works with infants and toddlers, and uses her communication skills daily to stimulate each child’s emotional and intellectual growth.
