Container cloud computing: how STACKIT gets your applications moving

Just as standardized freight containers have revolutionized global logistics, containerization is changing the way we develop, deploy and manage software applications. Instead of moving large, cumbersome IT structures from A to B, individual applications now travel as isolated units through flexible cloud environments. Securely packaged, independent of the operating system and ready for use at any time.

With container cloud computing from STACKIT, complex applications can be effortlessly broken down into smaller, efficiently manageable units. Each of these units comes with everything it needs to run – including all dependencies, configurations and runtime environments. Like a freight container on the high seas, it can dock on any compatible server: locally, in the public cloud or in a hybrid infrastructure.

This saves costs, increases scalability and makes migration easier than ever before. At the same time, as a developer you gain full control over your application and access to modern solutions such as Docker and Kubernetes. This enables automated management, fast updates and reliable operation.

How container cloud computing with STACKIT works in practice

Whether microservices landscapes, individual software applications or entire platform architectures: with STACKIT, you can run your application containers and their dependencies flexibly, securely and efficiently in the cloud. You can choose between two powerful solutions that complement each other perfectly depending on your requirements and expertise:

STACKIT Kubernetes Engine (SKE): For complex, scalable architectures

The STACKIT Kubernetes Engine is the right choice for companies that operate sophisticated, distributed systems and microservices. It can be used to manage, scale and automatically update thousands of containers simultaneously. Features such as self-healing, resource management and seamless integration into DevOps workflows make the SKE particularly attractive for teams that place the highest demands on flexibility, control and scalability.

STACKIT Cloud Foundry: For fast development and easy deployment

Anyone looking for a lean and fast solution for development, testing or smaller productive workloads is well advised to use STACKIT Cloud Foundry. The platform offers a preconfigured environment in which application containers can be deployed without in-depth prior knowledge. Features such as automatic scaling, simple connection of services and automatic repairs and updates make Cloud Foundry ideal for agile teams who want to achieve fast results with minimal effort.

Practical examples: How various industries rely on container cloud computing with STACKIT

Administrations are faced with the challenge of modernizing existing applications without jeopardizing ongoing operations. With STACKIT, administrative applications can be bundled in Docker containers and gradually migrated to the cloud – via Kubernetes or Cloud Foundry, depending on their complexity. This enables continuous digitalization while maintaining process security. New services can be introduced more quickly and existing applications can be managed automatically and operated more efficiently in the long term.

Data protection is a top priority in the healthcare sector. Providers of medical software solutions rely on Confidential Kubernetes to reliably protect sensitive patient data. End-to-end encryption and isolation of the Kubernetes cluster from the infrastructure means that third parties cannot access the data. The requirements of the GDPR and industry-specific certifications are met. At the same time, Cloud Foundry enables the uncomplicated provision of additional services, for example for short-term feature enhancements or scaling for new user groups.

In online retail in particular, systems must be able to respond to high peak loads at short notice. Scalable platforms are a must in e-commerce. STACKIT offers the option of operating web stores as a microservices architecture – including automatic scaling for discount campaigns such as Black Friday. Marketing functions or analysis tools can be quickly created and tested with Cloud Foundry. Thanks to central administration and usage-based billing, infrastructure and costs can be kept under control at all times.

Practical tips for your entry into container cloud computing with STACKIT

With the right preparation and the right tools, your entry into the world of containerization will go smoothly. These tips will help you to set up your container environments securely, efficiently and sustainably:

Think automation right from the start: avoid manual configurations wherever possible. Tools such as Terraform allow you to define your infrastructure as code – repeatable, verifiable and efficient. This allows you to lay a stable foundation for the scalable operation of your applications.
Integrate security right from the development stage: The earlier you consider security aspects, the better. Take the “shift-left” approach: integrate container scanning into your CI/CD pipelines and use role-based access controls to identify potential vulnerabilities in good time.
Plan and scale resources smartly: Always keep an eye on the utilization of your containers. With STACKIT’s integrated monitoring tools, you can detect load peaks at an early stage and use automatic scaling to counteract them cost-effectively and in line with demand.
Prepare the migration carefully: Before moving your application to containers, you should check what dependencies exist – for example, to databases or an external service. Make sure that important data remains backed up and available outside the container.
Keep an eye on costs: Containers offer efficiency – but only if you actively manage cloud usage. STACKIT helps with detailed billing and flexible quota models so that you can keep control of your costs at all times.
Use documentation and support: It’s worth taking a look at the STACKIT documentation, especially when getting started. There you will find step-by-step instructions, best practices and background knowledge. Personal service and support is also available if required.
