1. Introduction to the IBM C9004800 certification

IBM Certified Developer - Cloud Native Java with IBM Liberty 2023 (C9004800) is a globally authoritative enterprise level professional certification in the field of cloud native Java development launched by IBM, belonging to the core development sequence of the IBM Java & Cloud Native Certification Program.

The IBM C9004800 certification focuses on verifying the ability of practitioners to build scalable, highly available, and secure cloud native Java applications and microservices based on IBM Liberty 2023, Jakarta EE 10, and MicroProfile. The aim is to cultivate professional technical talents who can independently lead the full lifecycle development of enterprise level cloud native Java applications.

Against the backdrop of accelerated popularization of cloud native architecture and deepening digital transformation of enterprises, IBM Liberty, as the "benchmark for enterprise level cloud native Java runtime," undertakes the core responsibilities of modernizing traditional Java applications, building cloud native microservices, and supporting hybrid multi cloud deployment.

The core positioning of the C9004800 certification is to cultivate "full stack development experts for IBM Liberty cloud native Java applications," not just developers who master basic Java syntax, but those who can deeply understand the core principles of cloud native architecture and proficiently use IBM Liberty 2023, Jakarta EE 10, and MicroProfile to build highly available microservices capable of application containerization deployment, configuration management, security reinforcement, performance optimization, and troubleshooting.

Simultaneously, it can seamlessly integrate with IBM ecosystem products and third-party cloud platforms, becoming the core technical support for enterprise cloud native Java application development, modernization transformation, and continuous optimization.

2. The Competitive Edge of IBM C9004800 Certification

C9004800 is an officially recognized core qualification for Liberty cloud native Java development by IBM, and is highly recognized in IBM's ecosystem cloud native projects. This certification is the core indicator that distinguishes between "traditional Java development" and "cloud native Java specialized capabilities." 

With the popularization of cloud native technology, the demand for professional cloud native Java development talents in enterprises has surged. The average monthly salary of C9004800 certified personnel is 35%-50% higher than that of uncertified Java developers. The certificate holder has obvious advantages in core project role allocation, career promotion, and salary negotiation, becoming the core technical backbone of enterprise cloud native transformation and greatly expanding career development space.

IBM Liberty is the core runtime for enterprise level complex cloud native projects, and C9004800 certification is a necessary qualification for undertaking high-end projects such as cloud native transformation of core trading systems in the financial industry, construction of retail omni channel microservice platforms, and development of government big data applications.

The certification covers IBM Liberty 2023 core development skills, cloud native best practices, and industry solutions, demonstrating the ability to lead the implementation of enterprise level cloud native Java applications. Holders can join the IBM Developer Community to access Liberty's latest technical documents, product roadmaps, and development solution templates; prioritize participation in IBM's offline technology summit and cloud native practical workshops, connect with high-end cloud native project resources and technical experts within the IBM ecosystem, and continuously improve professional capabilities.

After passing C9004800, holders can advance to IBM Certified Cloud Native Application Developer Expert or switch to architecture design positions, with a clear career development path. The cloud native thinking, microservice building capabilities, and DevOps practical experience cultivated by this certification can help holders break through the professional limitations of traditional Java development and adapt to the long-term demand for composite cloud native talents in enterprise digital transformation.

3. Core Components of the IBM C9004800 Certification

The IBM Liberty 2023 certification exam aims to comprehensively validate your comprehensive ability to design, develop, deploy, and operate modern Java microservices using Liberty as the core runtime in the cloud native era.

The exam content strictly follows the official outline of 2023, starting with cloud native architecture and the foundation of IBM Liberty 2023. The core is to understand how Liberty's lightweight and modular design perfectly fits cloud native principles and master its development and debugging toolchain.

Core development capabilities focus on Jakarta EE 10 and MicroProfile core API development, as well as best practices for microservice design and implementation. This requires you to not only be proficient in modern Java enterprise level development such as RESTful APIs and data persistence, but also to master the use of MicroProfile to implement production level microservice features such as configuration, fault tolerance, and monitoring.

Application containerization and cloud deployment, as well as application security reinforcement and compliance modules, ensure that your applications can be safely and standardly delivered to hybrid cloud environments such as Kubernetes.

Performance optimization, resource management, observability, and troubleshooting are key to ensuring high-quality application operation. We examine your ability to build a complete observability system from JVM tuning to utilizing logs, metrics, and link tracing.

Finally, DevOps and Continuous Delivery modules link all the aforementioned skills together, guiding you to build an automated and repeatable CI/CD pipeline for efficient and reliable software delivery.
