Atmosphere is an open-source OpenStack deployment tool that provides a full suite of cloud infrastructure management capabilities. It is designed with versatility to support Cloud, Hosted, and On-Premise editions. It is engineered for a broad range of deployment scenarios, promoting both flexibility and scalability. Utilizing Kubernetes and OpenStack-Helm, the tool automates the deployment process, offering an efficient and repeatable method for provisioning OpenStack resources.   

The platform is fortified with built-in monitoring and alerting features, offering administrators real-time insights and swift issue resolution to maintain a reliable and high-performing cloud ecosystem. Atmosphere’s integration with Keycloak provides robust identity management, including Single Sign-On (SSO) and support for protocols like LDAP, SAML, and OpenID Connect, thereby enhancing security and streamlining access.   

Atmosphere’s deployment strategy is backed by Ansible inventories and detailed guides, ensuring a secure and structured setup of essential components, such as Ingress, Horizon, and Cinder.    

Atmosphere’s Container Storage Interface (CSI) configurations enhance Kubernetes cluster performance, while automated SSL certificate management through cert-manager and integration with a pre-configured Ceph cluster offer simplicity and efficiency in managing block storage and image services.  Recognizing the diverse storage needs of organizations, Atmosphere extends its support beyond the integrated Ceph cluster to include alternative storage backends. 

Networking capabilities are optimized with advanced configurations, including hardware acceleration technologies like Mellanox ASAP2 and Open vSwitch (OVS) offloading, facilitated by the netoffload project for SR-IOV preparation. These enhancements lead to improved network throughput and reduced latency.   

Further adding to its robust suite, Atmosphere’s custom Cluster API driver for OpenStack significantly simplifies the orchestration of Kubernetes clusters. This allows for an integrated management approach to both containerized workloads and virtual machine instances, fostering a harmonious ecosystem where modern, cloud-native applications can coexist and interoperate with legacy workloads. This duality maximizes the utility and efficiency of the infrastructure, offering businesses the agility to adapt to changing market demands.   

Migrations to Atmosphere are streamlined, regardless of whether you are transitioning from VMware, AWS, or another environment. The process is designed to be straightforward, minimizing disruption and ensuring a smooth transition to Atmosphere’s robust cloud infrastructure. 

In summary, Atmosphere provides an end-to-end solution for organizations seeking to deploy and scale OpenStack environments. It embodies the collaborative spirit of the open-source community while delivering the stability and support expected from enterprise-grade software.

Atmosphere was among the open source tools highlighted in a recent white paper published by the OpenStack community, Building the Open Infrastructure Blueprint: How Linux, OpenStack, and Kubernetes Combine to Deliver an Open Source Powered Infrastructure Stack.
