What is Full-Stack Development?

 

What is Full Stack Development, Definition?

Full-stack development refers to the development of both front-end and back-end portions of an application. This web development process involves all three-layer- The presentation layer (front end part that deals with the user interface), Business Logic Layer (back end part that deals with data validation), and the Database Layer. It takes care of all the steps from the conception of an idea to the actual finished product.

Having a specialist work on each of the different subsystems of the web development process proves quite complex and expensive. Companies are demanding full-stack developers who are proficient in working across multiple stacks.

What is a full-stack developer?

A Full-Stack Web Developer is a web developer or engineer who works on both the front-end and back-end of a website or application — meaning they can tackle projects that involve databases, building user-facing websites, or even work with clients during the planning phase of projects. Being a Full-Stack Developer doesn’t mean that you have necessarily mastered everything required to work with the front-end or back-end, but it means that you are able to work on both sides and understand what is going on when building an application.

In fact, “full-stack” refers to the collection of a series of technologies needed to complete a project. “Stack” refers to a collection of sub-modules. These software sub-modules or components combined together to achieve the established function while without the need for other modules.

Technology related to full-stack development:

There are some essential technologies that you must learn in order to call yourself a full-stack developer. Here is a quick guide to what technologies you must learn.

HTML and CSS-

To begin your career in web development you must have the fundamental knowledge of HTML and CSS. They are the basic building blocks of the web that enable you to add content and styles to your web pages. So start your journey of becoming a full-stack developer by gaining a sound understanding of these front-end concepts.

JavaScript-

The fact that JavaScript can be used both in front-end and back-end development makes it very popular. It is one of the hottest technologies in the market where continuous innovations take place. With new tools and frameworks getting released every year, one needs a piece of sound knowledge in this area. Knowledge of JS frameworks like AngularJS and ReactJS would help one to write long codes with ease. A solid understanding of jQuery would be an added advantage.

Backend Programming Languages–

After gaining a strong foothold in the front-end arena next comes backend languages like Ruby, Python, PHP, etc. which handle application logic, user authentication, and data operations. Start with a language that is easier to learn. Whatever language you choose, just make sure you are thorough with its nuances. You may learn Node.JS which is based on JavaScript that you would have already learned before reaching this point.

Database & Web Storage-

In order to design and develop dynamic websites, one should surely know how database-driven websites store and access data. Learn the benefits of relational database management systems like SQL. Understand how to connect a backend language with a database. Gain knowledge about web storage so that you know how to store cookies, sessions, and cached data in the browser.

HTTP and REST-

You must gain insights into HTTP- that is the protocol required to facilitate communication between the client and server. You must also know how REST is important to the HTTP protocol and web applications. Knowledge of Chrome DevOps Tools and SSL certificates would be advantageous.

Additional skills set to adopt as full-stack developers are as follows.

Application Architecture-

Developing complex applications would require a deep knowledge of how the code should be structured, how the data needs to be structured in the database, how to separate files, where to perform computational tasks, and where to host large media files. So a full stack web developer surely needs a deep knowledge of web application architecture.

Version control system-

A full-stack web developer needs to be well versed with a version control system. An understanding of GIT will help you keep track of any changes that you make to the code base.

Acquiring expertise in so many technologies and becoming an expert in all the layers of web development may seem like a daunting task in the beginning. It’ll be hard work learning all of this, but it’s rewarding in the end and Full-Stack Development is fun!

How to Migrate to Microservices

Migrating to Microservices may be risky, costly, and time-consuming unless the strategy is very well-defined in the beginning. Migrating to Microservices has been beneficial to many Fortune 1000 companies, which confirms its transformation potential to a variety of industries.

Our developers at Charter Global have expertise in Microservices, DevOps & QA Automation. We have successfully implemented in several Fortune 1000 companies, including Financial, Healthcare, and Retail & Media.

Charter Global recommends a practical three-step Microservices approach to focus on the business functionality allowing self-contained units to represent a module’s end-to-end functionality.

Learn More about How to Implement Microservices Framework Developed by Charter Global


Migration Approach

In order to migrate to microservices, you must first make a decision on a microservices architecture. Before trying to optimize its implementation, it is necessary to evaluate how the services will interact. Next, continually optimize those speed gains that microservices architecture provides. This requires flexibility in the tools used in deploying the architecture.

To migrate to microservices, a practical three-step approach is suitable:

Componentize: From your already existing applications, select a component and create a microservices implementation on a pilot basis.

Collaborate:  All stakeholders, programmers, and developers on the team should know about the techniques and lessons learned from the Pilot in Stage One. This keeps them updated with new processes and initiatives.

Connect: Complete the application and connect to users in a real-world scenario.



Microservices Benefits

Microservices Architecture comes with a lot of benefits. Some of which include:

Agility: Banking and Fintech applications are designed to be complex, constantly evolving and scaling, integrating with multiple systems (internal/external) as well as demand high security at various levels. Microservices support greater agility in building and managing these systems making them highly suitable.

Scalability:  Unlike a monolithic application that has a lot of resources wasted for scaling services that are not required since they are all packed together in a single deployable unit, each microservices can scale independently without affecting the other microservices.

Availability: Failure of one microservices does not affect other microservices, as the failed one can be uninstalled and rectified quickly with minimal downtime. It does not require the entire application to be brought down for maintenance, unlike the monolith application.

Maintenance: A separate microservices is created for each business service. This means that the amount of codebase is reduced and functional changes can be faster and more efficient due to the decomposed architecture.

Separation of Business Concerns: Microservices offer a clear separation of business concerns as each Microservices caters to particular business functionality.

Faster Deployment: by catering to single business functionality, the code-based required for microservices are reduced, creating a rapid deployment.


Charter Global

While migrating to microservices might be risky, costly and tasking, the inclusive quality of the application is undeniably bound to increase in the long run, provided that the strategy is rightly planned. Migrating to microservices has been beneficial to Fortune 1000 companies, ultimately confirming its potential for transformation for all varieties of businesses.

Our developers at Charter Global are experts in QA automation, DevOps, and Microservices, providing skilled resources, tools, and guidance in implementing DevOps processes and Microservices architecture.


Wrapping Up

This plan for migrating existing applications to microservices is intended to enable organizations to realize the benefits of microservices architectures, such as resilience, scalability, improved time to market, and easier maintenance, with maximum efficiency and minimal disruption to existing applications and services.
