1. Introduction
Container technologies have become a crucial success factor for the digital transformation strategy in the public sector. This technology is primarily used to simplify and accelerate the deployment of applications, make the use and management of resources more efficient and transparent, and increase the security and stability of IT infrastructure. Containers are software packages organized to include all elements (code, runtime, configuration, and system libraries) necessary to run the software. In this way, containers virtualize the operating system, are independent, and can therefore run anywhere and in isolation. In the public sector, this technology plays an important role as it significantly improves the effectiveness, efficiency, and security of public services for citizens. This article focuses on the introduction, use, and potential of this technology in public organizations. It highlights the benefits, existing challenges, and opportunities of this innovative technology for the public sector. Additionally, it examines specific challenges related to regulatory compliance and the complexity of the IT landscape in the public sector.
Recent studies show that container technologies are increasingly being used in the public sector to make IT infrastructure more efficient

.
The analysis is based on results and insights from current research and case studies. Many organizations, especially in the public sector, have a complex IT landscape composed of current and legacy technologies. However, this IT landscape needs to become flexible, secure, and easily adaptable. The introduction of container technologies helps to achieve the stability, scalability, and security of IT environments to optimally develop, deploy, and operate applications. Furthermore, container technologies offer a high degree of portability compared to traditional virtualization methods, enabling organizations to scale their operations flexibly and as needed. Additionally, this technology promotes organizational excellence by providing methods such as logging, monitoring, and user management.
Despite the many advantages this technology brings, public organizations face significant challenges related to regulatory compliance, integration into existing systems, and a lack of expertise. Moreover, driving factors such as flexibility, efficiency, security, and growth in an ever-changing digital environment make IT departments sought-after catalysts for digital transformation. With the right strategy, tools, and expertise, IT departments in public organizations can leverage container technologies to foster and advance innovation and digital transformation. This can, in turn, lead to productivity gains and cost savings.

3. Literature Review
Historical Context
Over the past few years, container technology has transformed significantly, expanding its use from niche markets to the public. In contrast to the private sector, which quickly adopted container technology to increase efficiency and scalability, the public sector has been slower to react due to security concerns and regulatory requirements. Container-based solutions create a unified and stable environment for developing, testing, and deploying applications, thereby significantly reducing deployment time. They are replacing traditional virtualization techniques in IT infrastructure to improve cost-effectiveness and flexibility
.
The foundation of container technology is based on the concept of combining and thus isolating all dependencies of an application in a single, independent area called a virtual container, thereby increasing the portability of applications. The application's libraries, setup files, and binaries are all included in this encapsulation, which ensures that they will run consistently in any environment. This isolation ensures that applications work consistently regardless of the underlying hardware or operating system. When compared to traditional virtual machines, containers are more efficient and can start up more quickly. This is because they use the base of the host operating system and are naturally lightweight. The use of this technology has enhanced the deployment of applications in a more efficient and reliable way through its focus on portability, scalability, and isolation

.
The modern era of container technology started in 2008 with the so-called release of Linux Containers (LXC), which separated applications into namespaces and groups. The year 2013 witnessed a breakthrough in container technology with the release of Docker – a platform with various components that abstract some of the tedious tasks that users would otherwise have to deal with in the low-level virtualization of operating systems, this innovation made it simpler to bundle applications with their dependencies by providing a framework for building, deploying, and managing containers

.
Container management systems such as Kubernetes have now emerged as the standard platform for large-scale automating deployments. The objectives of both container technologies and conventional virtualization techniques are efficient utilization of resources and program execution. However, these objectives are pursued through distinct approaches. Conventional virtualization involves the operation of multiple operating systems (OSs) on separate virtual machines (VMs) on a single physical computer. Containers are designed to be diminutive and expeditious, leveraging the base operating system and constrained execution within user-defined domains. According to extant studies, containers utilize less system resources and initiate and terminate faster than virtual machines. This capability, or so-called feature, is highly beneficial for microservices as well as cloud-native initiatives. Even though current container-based technologies offer better isolation and security, the shared kernel in containers might still pose a security threat
.
Theoretical Frameworks
In recent research, various theoretical models have been used to address the challenges of container orchestration, specifically container management, organization and security, including the following one:
1. Orchestration through machine learning can improve container orchestration. These models use probability-based, knowledge-based and evidence-based data fusion algorithms to effectively address data challenges using core components such as model selection, generation, optimization, evaluation, deployment, testing and data collection in model development. Based on this, deployment plans can be optimized, scaled and automated

[9]
.
2. Security frameworks depend on the specific requirements and context of organizations' IT landscape and thus influence the use of container technologies. The main purpose of security frameworks is to provide guidelines and recommendations for dealing with security concerns and challenges related to container technologies during the planning, implementation and maintenance of the container stack. In addition, security frameworks should optimally support mechanisms for rapid detection, optimal monitoring and isolation of threats

[10]
.
3. Digital twin models are executable, simulation-enabled virtual models of physical systems that improve system performance and enable timely analysis of large amounts of data using real-time data from intelligent sensors. These models also help to predict system performance, adapt system behavior and accelerate decision-making processes by exploring different use cases and quickly evaluating expected outcomes under different operating conditions. These models have been successfully used in logistics and value chain management
| [6] | J. Lyu, F. Zhou and Y. He, "Digital technique-enabled container logistics supply chain sustainability achievement," Sustainability, 15(22), 16014, https://doi.org/10.3390/su152216014 2023. |
[6]
.
4. Cloud-native frameworks such as Kubernetes for the management of containerized applications has been the subject of a significant amount of research. These frameworks make it easier for application containers to be installed, scaled, and run automatically across host groups. In recent years, the focus has shifted from the theoretical study of Kubernetes to its practical application. These models also make it possible to minimize risk by transforming large applications into smaller, distributed systems while addressing key cloud issues
| [11] | J. Alonso, L. Orue-Echevarria, V. Casola, A. I. Torre, M. Huarte, E. Osaba and J. L. Lobo, "Understanding the challenges and novel architectural models of multi-cloud native applications – a systematic literature review," Journal of Cloud Computing, 12(6), https://doi.org/10.1186/s13677-022-00367-6 2023. |
[11]
.
These models show how several strategies might be used to deal with the difficulties and complications that come with container technology.
Containerization
Containerization represents a comprehensive concept of procedures, methods, and tools that enable the efficient deployment and management of software applications. In this process, software code is isolated and packaged with only the necessary operating system libraries and dependencies required for execution, allowing it to run uniformly and consistently in various environments as a lightweight executable file, also known as a container. In contrast, virtual machines (VMs) enable the concurrent operation of multiple operating systems on a single physical machine. Containerization improves and accelerates the software development process, offering higher portability and efficiency, thereby saving resources
.
Docker is a platform with various components, such as Docker Engine, Docker Images, Docker Containers, Docker Hub, Docker Compose, Docker Swarm and Docker Registry, that abstract some of the tedious tasks that users would otherwise have to deal with in low-level operating system virtualization. In other words, Docker lets you separate your applications from your infrastructure to quickly deploy software

[12]
. Docker containers exhibit a low memory consumption during their creation. A virtual machine (VM) generally necessitates at least 512 megabytes (MB) of disk space, whereas a Docker container can be created for a mere few kilobytes

[13]
. There is a separation between the "client" and the "daemon". The core component of the Docker platform is called the Docker Engine, which is completely open source and consists of three distinct parts: The Docker Daemon, a core service that manages Docker containers; the REST API, an intermediate layer responsible for interacting with the Docker Daemon; and the Docker Client (CLI), an interface layer that users interact with.
Adoption of Container Technology in Public Organizations
Container technology is used by many IT departments in public sector organizations to deploy and handle their applications because it has so many benefits. Datadog shows that the number of businesses using serverless containers grew from 31% in 2021 to 46% in 2023 (see Data Availability Statement). This implies increasing usage of it among people. This trend indicates that companies are growingly fond of container technology. Businesses are applying it to save running costs and boost the innovation rate in their goods and services

Structure and Use of the Container Platform
The container technology ecosystem (see figure below) represents the entire development and deployment process of container-based applications. This ecosystem, consisting of several subprocesses (development, Continuous Integration/Continuous Deployment (CI/CD), deployment, operation, maintenance), offers high scalability, portability, and resource efficiency for developers and simplifies the development process. Developers can efficiently develop, test, deploy, and manage applications under good security standards. This efficiency particularly benefits public sector organizations, which often need to integrate different systems
