Infrastructure Modernization

Containerization is a process of migrating traditional applications or services to the containerized environment. The general procedure for containerization is as follows:

• Evaluation and planning: First, evaluate the features, dependencies, and architecture of applications or services. Determine which are suitable for containerization and make a reconstruction plan.
• Container platform: Select a container platform that meets your requirements. The most common containerized platform is Docker, but there are other options, such as Kubernetes.
• Containerized application: An application is split into small modules or microservices, and each module is packaged as an independent container image. Use Dockerfile to define the process of building container images, including dependency installation, configuration, and startup commands.
• Container orchestration and management: Container orchestration tools, such as Kubernetes, can be used to manage multiple container instances and implement functions such as automatic scaling and load balancing. You can define the deployment and running modes of containers by compiling configuration files or using command line tools.
• Network and storage configuration: Configure the network communication between containers and the mode for accessing external resources. Ensures that a container can interact with other containers, databases, and message queues, and ensures data durability and reliability.
• Security and monitoring: Ensure the security of the containerized environment by restricting container permissions, using secure image sources, and scanning vulnerabilities. In addition, a monitoring system is set to monitor the performance and running status of containers in real time.
• Test and deployment: After the containerization is complete, perform comprehensive tests: unit test, integration test, and performance test. Ensure that applications run properly in the container environment. Then, use automation tools or scripts to deploy the container to the production environment.
• Continuous integration and delivery: Establish a continuous integration (CI) and continuous delivery (CD) process to quickly and reliably build, test, and deploy new versions of containerized applications.

Containerization is a complex process and requires careful planning and evaluation. Before you start, you need to take a deep dive into the containerization technology and the platform you selected, and select the appropriate tools and methods as required.
