Discover how to make the best use of the cloud technology behind the Open Telekom Cloud.

This module will familiarize you with the public cloud. You will also learn how the Open Telekom Cloud (as an OpenStack cloud) differs from the other public clouds. Applications operated in public clouds require new approaches to ensure their availability and provide protection against failure. You will be introduced to the tools with which you can achieve both objectives and you will learn how to manage the Open Telekom Cloud efficiently.

• Core properties and history of the Open Telekom Cloud
• Basics of cloud technology
• Availability zones and high availability of applications
• Security patterns
• Administration patterns, use of tagging
• User interface (console)

Learn how to secure your cloud and what you need to watch out for when accessing the cloud.

You cannot use public clouds without basic network functions. Network functions ensure that cloud resources are available from your workplace, but also to the users of the service you operate. In addition, the network resources allow you to secure your private cloud resources and provide the basis for growth and shrinkage of the service depending on the number of queries.

• Network connections with decision-making tools (for choosing the suitable access)
• Virtual Private Cloud and subnet
• Routing and network address translation (NAT)
• Elastic IP
• Load balancing
• Security and security groups
• Jump hosts and tunneling

Learn how to create servers and storage systems and use them for applications.

The third module explains which servers and storage systems you can use. The respective server and storage should always fit the respective application, so that costs and performance can be coordinated ideally. We will also show you which paths can be used for safe access to your servers and which operating systems you can use.

• Flavors and Elastic Cloud Server (ECS) – performance classes
• Operating systems and images
• Types of storage and their use
• Pricing and billing
• Creating servers and login processes
• Key pairs – use and best practice
• Login via SSH or Remote Console

Learn how to prevent data loss.

In the final module we explain how you can prevent data loss and “archive” your services when you do not need them. In real life you most likely work on a project with other colleagues – we will show how to organize this collaboration and how you can contact our support quickly in case of an emergency.

• Backup options
• Restoring servers and data
• Private images for your own applications
• User data injection
• Organizational structure and permission concepts for users, projects and tenants
• User management
• Creating tickets
