Containerization

• Collaboration between software providers and production environment administrators is inefficient.
• The cycle of delivering new, minor modifications to applications takes as long as delivering a completely new version of the application.
• We are unable to respond quickly to increased application loads caused by a growing number of users.
• We need to update the application, but we already know that part of our data processing will be carried out in the cloud.
• We are moving IT resources to the cloud-whether private, public, or hybrid.

• Faster market introduction of new products and services in line with market needs and dynamics, thanks to more efficient delivery of modern applications (shortened Time to Market) while maintaining reasonable Total Cost of Ownership (TCO).
• Increased innovation by the IT team in creating new services and solutions by reducing the amount of repetitive tasks.
• Enhanced service availability through reduced downtime caused by the deployment of new functionalities.
• Uninterrupted access to applications thanks to built-in high availability mechanisms and system fault tolerance.
• Cost optimization of support by reducing the duration of failures.

Containerization facilitates troubleshooting and bottlenecks in existing applications and opens up opportunities for developing new applications by:

• increasing the flexibility of application delivery through the adoption of a cloud-native approach;
• hosting traditional applications in a modern, portable environment;
• running analytical applications and data science tools in a new scalable environment;
• continuously updating software and delivering new modifications using the CI/CD process and tools;
• enhancing application security through isolation, network segmentation, environment standardization, and monitoring;
• automating administrative and development tasks within the CI/CD process;
• reducing the labor intensity of administrative tasks, thereby optimizing the costs of application service;
• improving communication and cooperation between developers creating applications and administrators responsible for their proper functioning in the production environment (DevOps approach).

Key technologies currently used to deliver and manage container-based applications include:

• Docker: A tool that enables the creation, packaging, and delivery of application containers, as well as their management;
• Kubernetes: A platform for managing containers that automates the processes of deploying, scaling, and managing container-based applications;
• Rancher: A container management and orchestration tool that provides simple and efficient control over container infrastructure;
• OpenShift: A container management platform based on Kubernetes that facilitates the deployment, scaling, and management of applications in the cloud;
• VMware Tanzu: A container management solution that integrates with VMware infrastructure, allowing for the deployment and management of containerized applications in a virtualized environment.
