25 Learning and development skills in 2023
25 Learning and development skills in 2023 that will make you a successful person in 2024.
Employers who have experienced employee loss due to layoffs or resignations must rely on the capabilities of their remaining workforce. Additionally, flourishing businesses must exert every effort to encourage the professional growth of their desired staff.
According to a recent McKinsey & Company poll, the biggest reason individuals leave their jobs is a lack of professional advancement. This was far more prevalent than other reasons for leaving, like a lack of satisfying jobs or workplace flexibility.
L&D teams must continuously develop and expand if they are to assist workers in realizing their full potential. Here are the 25 Learning and Development skills for 2023 because we request their input:
The first one in Learning and development skills is microservices. This Term has been around for a few years, so you may have heard of it. Microservices gained notoriety when they were adopted by start-ups like Uber and Netflix, but they offer much more. Simplicity is a key microservices principle.
Microservices divide a program into several smaller, composable parts, making them easier to create, develop, and manage than monolithic applications, which are challenging to build and maintain.
There is a rising demand for Java programmers with expertise in Microservices.
- Apache Kafka
Those of you who are unfamiliar with Apache Kafka should know that it is a distributed data streaming solution that enables real-time publishing, subscribing, storing, and processing of record streams. The Apache Software Foundation received a donation from LinkedIn for its creation. It was created using Java and Scala.
It aims to address the requirement for a unified, high-throughput, low-latency platform for the real-time management of data flows in many contemporary systems.
You might be qualified for some of the most intriguing Java career possibilities available worldwide if you have this on your resume. This is one of the top technologies that is becoming more well-known in the Java market.
- Spring Boot
Spring Boot has been on my list of the top 5 Java frameworks to learn for a time now. Like how the Spring framework makes it easier to develop Java apps by minimizing boilerplate code and facilitating testing through dependency injection.
Most of the necessary components are automatically configured by Spring Boot, making it easier to use the Spring framework and reducing the time required to start your Java project.
Since most new development projects use Spring Boot, I strongly advise learning it if you don’t already.
- Spring Framework
Spring is without a doubt king of the Java stack. It is a requirement, not an option, for a Java programmer. Recently, Spring Boot has also become widely used, but Spring is still required as a minimal minimum.
It not only offers dependency injection, which makes it simpler to write testable code but also various libraries and utility classes, such as JdbcTemplate, which improve Java programming daily.
Don’t worry if you are unfamiliar with the Spring Framework; this is the perfect moment to learn it.
- Cloud Computing
All other forms of technology are gradually being eclipsed by cloud computing. The next generation of Java cloud programs will be created as more businesses shift their operations to the cloud and as important cloud platforms like AWS, Google Cloud Platform, and Microsoft Azure expand and mature.
Along with teaching you how to make Java programs for the cloud, courses also teach you all the necessary methods and resources.
Another essential ability for any programmer—not just Java programmers—is this one. You simply cannot function without SQL because it is the most important tool for interacting with and analyzing data. Any programmer’s real king is data.
Given the expanding demand for data engineers, now is the ideal moment to learn SQL if you don’t already.
Since almost all modern online applications expose APIs or use REST API, this is another ability that Java programmers can leverage. REST is gradually being replaced by GraphQL, but in the Java world, REST still reigns supreme.
Check out different courses for Java developers on Udemy if you need some recommendations on where to study REST.
The way we create and deploy software is quickly evolving thanks to DevOps, and Docker has been a key component. A container called Docker abstracts away the particulars of the environment needed to run your code, such as installing Java, configuring the PATH, adding libraries, etc.
Docker is highly helpful in the software development and deployment process since it makes it simple to reproduce the environment without installing servers.
I urge any Java developer to study Docker so they can branch out and add this valuable talent to their résumé.
- Hibernate + JPA
The two most popular Java frameworks are Spring and Hibernate. It is the most used persistent framework in the Java world. Hibernate becomes a crucial framework for many Java applications because data is a crucial component of every Java application.
It frees you up to focus on using objects to create application logic by eliminating the bother of using JDBC to interact with persistent technologies, including relational databases.
I advise enrolling in Chad Darby’s Spring & Hibernate for Beginners (including Spring Boot) course on Udemy if you want to learn Hibernate.
- CI (Jenkins, Bamboo, GitLab, etc.)
Jenkins, in my opinion, is yet another essential competency for today’s Java developer, along with Maven. Most businesses currently use CI and CD, which have considerably enhanced software development processes and quality.
You should check out different courses on Udemy if you need references. During an Udemy sale, you can purchase this course for just $9.9.
Because it is currently the most widely used cloud platform, Amazon Web Service has established itself as a competence. People with experience using AWS technologies and settings like EC2, S3, and Virtual Private Cloud are in high demand.
In recent years, I have also observed many of my friends swarming to become AWS certified. If you’re interested in learning more about AWS, you may sign up for a number of free online programs.
The most important Java tool I’ve ever found is Maven. I am familiar with how difficult it was to gather and maintain dependencies for a Java programme because I came from the ANT and Batch script era before Maven.
In addition to resolving the dependency management problem, Maven provides Java projects with a consistent structure, which significantly lowers the learning curve for inexperienced engineers.
It is an essential skill for Java programmers to possess, and Maven is currently learning it if you don’t already.
- Elastic Search
The 13th in Learning and development skills is ElasticSearch is yet another fantastic Java software. You can rely on it to accurately search, analyze, and visualize your data because it is a search engine based on the Lucene library. The Elastic Stack, which consists of Elasticsearch, Kibana, Beats, and Logstash, is frequently utilized.
Elastic search is becoming more important as more applications now give users a method to analyze and view their data, and as a result, Java developers with ElasticSearch expertise are in high demand.
It has a variety of uses, including searching and analyzing log data similar to how Splunk does.
Service-oriented architecture is known as SOA. As the name suggests, a software design technique known as “service-oriented architecture” involves having application components connect with one another across a network to provide services to other components.
Vendors, products, and technological advancements have little bearing on the fundamental concepts of service-oriented architecture. The primary difference between it and microservice is that microservice, as its name implies, is substantially smaller in scale and both microservice and it divide the application into several services.
Because real-world applications are frequently complicated and built using SOA architecture, there is a high demand for Java developers.
The level of SOA skills is pretty high. If you want to learn more about SOA and acquire this ability, check out this list of the best SOA courses.
- Java EE
Some of you might be shocked to learn that one of the most in-demand skills for Java engineers is Java EE, often known as Jakarta EE. Today, Java EE is still widely used.
Numerous companies that include Java in their web stack use Java EE to build their applications.
Because it’s an essential ability for all programmers, not just Java programmers, I listed it among the competencies I believe every programmer should possess.
It is utilized everywhere, regardless of whether the codebase is open-source or closed-source. GitHub is the same way.
Best in Learning and development skills that will be in huge demand in 2024. NoSQL offers a different approach to data storage that scales well for many applications, especially those that load a jumble of properties simultaneously. This differs from the conventional relational approach of data storage, which normalizes the data to try to eliminate redundancy or duplication.
There are numerous well-known NoSQL databases on the market, including MongoDB and Cassandra.
If you’re interested in learning more about NoSQL databases like MongoDB, have a look at this selection of the best Mongo DB courses for beginners.
TDD is the one thing I would advise Java devs to learn right now. Although it is a very specialized talent for Java developers, practice is the single most effective way to raise your coding confidence and enhance the quality of your code. The test-code-test-refactor cycle of TDD is quick and effective with Java.
I strongly advise any Java developer to use TDD, and there is no better way to learn TDD than by reading the Test-Driven book. For me, it serves as the bible for TDD in Java.
I have long argued that Java developers should become familiar with JUnit. Additionally, it is one of the 10 skills I advise Java developers to obtain by 2023. Additionally, JUnit has improved, with JUnit 5 setting the bar. It makes writing tests more efficient and swifter.
You should become familiar with Mockito, a popular Java package for building mock objects, in addition to JUnit.
Since Java programs, including JDK, have heavily relied on the library, creating tests that can run in isolation requires a mocking framework like Mockito.
If you want to learn more, I advise you to look at this compilation of the top Udemy and Pluralsight JUnit and Mockito courses.
- Java SE
Given that Java SE is one of the most crucial abilities for any Java developer, I was somewhat shocked to see it listed at number 16 on the list. You simply cannot develop in Java if you are unfamiliar with Collections, Multithreading, Streams, and other essential Java SE libraries.
Any Java developer should have a solid understanding of these fundamental classes. Therefore, If you are new to Java, kindly take some time to learn and develop your foundational skills.
This is another contemporary, JVM-based, full-stack framework for creating serverless and microservice applications that are modular and easily testable. The Java community is quite supportive of Micronaut, and with major corporations like Oracle and JetBrains supporting it, it may soon be a serious competitor to Spring Boot and Spring Cloud.
If you want to learn MicroNaut in 2023 and need a resource, I also suggest you look into Daniel Prinz’s Learn Micronaut: Cloud-Native Microservices with Java course on Udemy. This 6.5-hour course is a fantastic tool for learning MicroNaut completely.
- Apache Camel
Java programmers can study this as well in 2023. An open-source integration framework called Apache Camel enables you to swiftly combine numerous data-producing and -consuming applications.
Given that data is the cornerstone of every application and that the majority of apps gather data from numerous systems before providing it as enriched data, Apache Camel is essential to data sourcing.
Apache Camel is a great option if you require message-oriented middleware with a rule-based routing and mediation engine in Java.
Quarkus is a native Kubernetes full-stack Java framework that optimises Java, particularly for containers, making it a powerful platform for serverless, cloud, and Kubernetes environments. Quarkus was developed for native compilation and Java virtual machines (JVMs).
Redhat is supporting Quarkus, which is swiftly gaining momentum for building scalable, high-performance Java applications? Applications built on the Quarkus platform are known for their quick startup times.
One of the easily available relational databases is MySQL, which is also widely used in the Java community. A solid understanding of a relational database like MySQL is very helpful in gaining a job as a Java developer because databases are an essential component of all Java applications.
Although I have experience with MySQL, SQL Server, and Oracle, if you are just getting started with a relational database, I recommend learning MySQL first.
If you require advice, check out this ranking of the top MySQL training programs.
Java application deployment practices are evolving quickly. The days of setting up a Tomcat instance, deploying a WAR file, or writing shell scripts to execute your primary Java apps are long gone.
Docker and Kubernetes are the two key technologies you need to construct and scale your Java Microservices in the era of cloud-native Java applications.
I’ve already outlined why running Docker and Kubernetes will be necessary for Java developers in 2023, so you might find it advantageous to include this experience in your resume.
Now you know all the 25 Learning and development skills in 2023 that will boom in 2024. Even if this is a list of the best learning and development abilities, it is always preferable to learn something new than nothing at all. It not only demonstrates your commitment to lifelong learning, a soft talent that industry leaders will be looking for in 2023, but it also enables you to come up with fresh ideas, increase your employment possibilities, and avoid becoming stuck in a rut.
Even with paid study time, it might be challenging to find the time to learn when you’re busy. Make learning a new skill (whatever it may be) every quarter one of your resolutions and carve out the time to do it.
