It contains most important capabilities & functions of program in server. Backend languages that can be used for programming are mostly Node. JS (for JavaScript), Django (for Python), Spring (Java) & many more.
Backend Development Roadmap :
- Knowledge of Web Server
- Programming Languages & Their Frameworks
- Version Control System (Git)
- Knowledge of Web Security
- APIs (Application Programming Interface)
- Containerization & Testing
- Deployment
- Cloud Providers
1. Knowledge of Web Server
Web servers run websites. It is able to store, process and provides (response) webpages according to request of user. When user sends an inquiry to web servers, request is received as request by an HTTP server, which identifies request & relays information to browser via HTTP. Web servers include Apache & NGINX as open source systems that provide information according to requests.
2. Programming Languages & Their Frameworks
Select & master any one of Programming languages as well as its frameworks.
- JSP+NodeJS JavaScript as most challenging programming language, you are able to investigate new concepts & create stunning web site. language is utilized to create dynamic, interactive sites. In case of JS there is an application framework called NodeJS It is designed using real time, push based systems using single threaded model to build backend API services. NodeJS lets you execute JavaScript on server.
- Python & Django Python+Django Python is among most simple of all programming languages. & when combined with Django is perfect role to create websites. Utilizing least amount of code, you will be able to create better & simpler web based applications. Python is preferred framework for web development & can be used to build faster implementations. Django is safest & flexible framework to use.
- PHP+Laravel PHP + Laravel PHP (HyperText Preprocessor) is scripting general purpose language which is ideal for web based development. It’s speedy agile, flexible & practical programming language that powers everything from blogs to most visited websites. Laravel is an open source framework utilized for creation of range of web based apps. It’s pure server side platform that processes information & makes use of MVC (Model View Controller) to separate back end of an application into parts that are logical, that make it easy to construct.
3. Version Control System (Git)
System for controlling version aids in maintaining & tracking code to use to implement future changes. These are tools for software that assist in managing changes made to source code in course of time. Gitwhich is open source & free could be ideal option for version control system due to its security customizable, easy to edit capabilities.
Why Git?
- It is among most widely employed version control system.
- It monitors changes that are made to file.
- Git branches cost nothing & are simple to join.
- It is possible to switch to certain versions any time you’d like to.
4. Knowledge of Web Security
Many threats could be threat to site & cause website to perform poorly. Web security is security measures & procedures that web developers need to use to create an efficient & efficient web site. It involves analyzing websites for weaknesses to protect against loss or theft which are caused by cyber hackers.
Some of risks developers have to face can include malware, backlisting or buffer overflows, as well as vulnerable data exposure. Different methods can be employed to prevent these issues
Utilizing HTTPS HTTPS is secure HTTP. When data is transferred via HTTPS it is secure through Transport Layer Security protocol, that has three layers of security:
- Encryption Method of protecting information with help of key or password “key” which is used to decrypt information.
- Data Integrity If integrity of data is assured information that is stored in database will be correct, comprehensive and reliable over course of time.
- authentication This technique protects from attacks while building confidence in user, which is response to growth of business.
Making sure you have secure backup process & recoveryData loss can be most significant threat to security breach. For this reason, be sure that you have an effective backup procedure. process can be carried out by variety of methods:
- The protection of media & information from destruction or theft.
- Regularly testing backups.
- Use rule of two persons to ensure that no one can be able to access media or content without permission from another document.
Other methods of attack include & other methods include XSS attacks, Software updates as well as SQL Injection.
5. APIs (Application Programming Interface)
A API is set of programs that are responsible for accessing data as well as interacting with external software, microservices and operating systems. It is essentially, it transmits feedback from users to system as well as sending results back to users. Through APIs (which function as an intermediary) that two programs can talk with each other. APIs are utilized by backend developers to establish connections between applications or services to establish communication & improve users’ experience. Express is an excellent option to use server in order to develop & publish APIs that allow for client server communications. most important APIs you must be aware of include:
- REST
- JSON
- SOAP
- GSON
- XML RPC
- AES
6. Containerization & Testing
Containerization is procedure of combining software along with all necessary components such as libraries, frameworks and others.. in order in order to separate services from one another in form of container. This is process used by backend developers in order in order to operate container quickly. Containers like Kubernetes & Docker are among two most frequently used containers.
Dockeris an open source containerization platform which lets developers bundle applications into containers. It’s similar as virtual machine, but far more effective. Its primary function is to allow software to work in various environments.
Kubernetes commonly abbreviated as “K8s”, automates deploying & managing cloud native apps by using cloud services that are public.
7. Deployment
If tests pass when testing is successful, developers can move to environment where they will be able to observe operation of their software. deployment can also be described as live environment. process consists of five steps including planning, development, testing, deployment and monitoring.
- Plan: When multiple developers are involved in an identical project having planning for deployment is essential. This step will help it will prevent conflicts between adjustments made & ensure that process of deployment is simple & effortless as it can be. This will result in rapid & effective creation of your application.
- development: Once, plan is completed, real development begins. This is where you come up with ideas & establish priorities for needs. Following that, administration of entire application could be transferred into testing.
- testing:Testing is crucial procedure to be sure that software isn’t prone to bugs prior to taking it to stage of production. Testing can only be done once you’ve deployed application across different environments in order to test whether it’s compatible with environment or is not. Examine for bugs, and, if there are any, be sure that you get rid of them follow up with process of deployment.
- Implementing: Seeing your application functioning live, free of issues and with perfected design makes you happy with work that was put in. This is process of pushing changes & changes from one platform to next.
- Monitor:Constant monitors are required in order to ensure that site works properly or not. There is possibility that problems may arise following website has been launched, therefore be on lookout for any issues as well as timing for launch should be planned in way that only minimum amount of people be able to view site & that changes could be made in order to view an optimized website application.
8. Cloud Providers
All things are moving to cloud. Be software, apps as well as services & items. Cloud computing. It’s form of computing on Web that allows individuals & businesses to utilize computing resources, such as computers, database services, processing & other events. Additionally, it offers pay as you go option. Cloud computing can be classified into three broad categories, software as Service (SaaS), Platform as Service (PaaS) as well as Infrastructure as Service (IaaS).
The most frequently used Cloud Services are:
- Amazon Web Services (AWS)
- Microsoft Azure
- Google Cloud
- Alibaba Cloud
- IBM Cloud
