Introduction to Safespring Cloud Platform on Empowering European Innovation

Creating and Managing SSH Keys in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

Join us in this detailed demonstration where we guide you through the process of creating SSH keys for secure access to the OpenStack environment.

Starting with the basics, this video covers the generation of an RSA SSH key using the ssh-keygen command, including optional passphrase settings for enhanced security.

We then proceed to illustrate how to handle the public key by uploading it to the OpenStack platform and managing key pairs within the system.

Implementing Server Groups in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

This video tutorial delves into the concept of server groups within OpenStack, a critical feature for ensuring that instances, particularly in high-availability setups like database clusters, do not run on the same physical hardware.

Safespring Cloud Architect, Gabriel, explains the distinction between different policies like affinity, anti-affinity, soft affinity, and soft anti-affinity, emphasizing the importance of anti-affinity for scenarios requiring true redundancy.

By walking through the creation of a server group named ‘DB Cluster’ with an anti-affinity policy, the video demonstrates how to configure and deploy instances that are guaranteed to operate on separate compute nodes.

Launching an Instance from an Image in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

This video provides a step-by-step guide on launching a new instance in OpenStack using an image as the source.

Starting from the Safespring portal, the tutorial covers the entire process, from naming your instance and selecting the appropriate image and flavor to configuring network settings and security groups.

You will learn how to choose between different storage and compute options, set up network connectivity including IPv4 and IPv6 addresses, and ensure your instance is secure through proper security group settings.

Mastering Security Groups in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

This tutorial offers an in-depth look at setting up and managing security groups within OpenStack, crucial for controlling access to instances across various network configurations.

Beginning with an overview of security groups’ role in defining what can interact within the OpenStack environment, the video guides viewers through creating and applying security groups named “frontend” and “backend” to manage web and database servers respectively.

The session demonstrates how to configure security rules that enable HTTPS and MySQL traffic, utilizing the capability to reference other security groups instead of specific IP addresses for scalability and ease of management.

Starting and Managing Instances from Volumes in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

This tutorial delves into the process of launching an OpenStack instance using a volume instead of the default image source, providing a more robust data storage solution.

The video begins by explaining the benefits of using volumes, particularly their ability to store data in multiple copies, reducing the risk of data loss due to hardware failures.

Viewers will be guided through the steps of creating a bootable volume from an image, selecting storage types for performance or cost efficiency, and configuring the instance with appropriate network and security settings.

Understanding Instance Types and Storage Options in Safespring

Fri, 19 Apr 2024 00:00:00 +0000

This tutorial video dives into the variety of instance types, also known as "flavors," available on the Safespring platform.

You will learn the key differences between B2 and L2 flavors, focusing on their storage capabilities. The video highlights how B2 flavors require an external volume for boot operations, whereas L2 flavors include built-in storage suitable for operating systems but with a caveat on data persistence and security.

This guide is essential for users looking to make informed decisions about instance configurations and understanding the implications of each flavor for their specific needs in cloud environments.

Understanding Network Configurations in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

This instructional video provides a detailed overview of network configurations available on the Safespring OpenStack platform.

This tutorial demonstrates the practical use of jump hosts to securely access instances that are not directly reachable from external networks.

Starting with a setup that includes instances in both public and default networks, the video shows the step-by-step process of transferring necessary SSH keys to a public jump host, enabling secure shell access to a backend instance located in a less accessible network.

Utilizing Jump Hosts for Secure Access in OpenStack

Fri, 19 Apr 2024 00:00:00 +0000

This tutorial demonstrates the practical use of jump hosts to securely access instances that are not directly reachable from external networks.

The guide emphasizes the role of security groups and network settings in ensuring secure and controlled connectivity across different network layers.
