## Azure Cobalt 100 Arm-based processor
9+
10+
Azure’s Cobalt 100 is Microsoft’s first-generation, in-house Arm-based processor. Built on Arm Neoverse N2, Cobalt 100 is a 64-bit CPU that delivers strong performance and energy efficiency for cloud-native, scale-out Linux workloads such as web and application servers, data analytics, open-source databases, and caching systems. Running at 3.4 GHz, Cobalt 100 allocates a dedicated physical core for each vCPU, which helps ensure consistent and predictable performance.
11+
12+
To learn more, see the Microsoft blog [Announcing the preview of new Azure VMs based on the Azure Cobalt 100 processor](https://techcommunity.microsoft.com/blog/azurecompute/announcing-the-preview-of-new-azure-vms-based-on-the-azure-cobalt-100-processor/4146353).
13+
14+
## OpenStack
15+
16+
OpenStack is an open-source cloud computing platform used to build and manage Infrastructure-as-a-Service (IaaS) environments.
17+
18+
It enables users to provision and manage compute, storage, and networking resources via APIs and dashboards, similar to those of public cloud providers.
19+
20+
OpenStack is widely used for:
21+
22+
* Private cloud deployments
23+
* Hybrid cloud environments
24+
* Edge and telecom infrastructure
25+
* Development and testing platforms
26+
27+
OpenStack runs efficiently on Arm-based architectures such as Azure Cobalt 100, enabling cost-effective and scalable cloud environments.
28+
29+
## Key services in OpenStack
30+
31+
OpenStack is composed of modular services that handle different aspects of cloud infrastructure:
32+
33+
* **Keystone (Identity):** Authentication and authorization service
34+
* **Nova (Compute):** Manages virtual machine lifecycle
35+
* **Glance (Image):** Stores and manages VM images
36+
* **Neutron (Networking):** Provides networking and connectivity
37+
* **Cinder (Block Storage):** Persistent block storage for instances
38+
* **Horizon (Dashboard):** Web-based user interface for managing resources
39+
40+
41+
## OpenStack architecture components
42+
43+
A typical OpenStack deployment consists of:
44+
45+
* **Controller Node:** Runs core services such as API, scheduler, and database
46+
* **Compute Node:** Hosts virtual machines using hypervisors
47+
* **Networking (Neutron):** Handles virtual networking, bridges, and routing
48+
* **Storage Services:** Provide block and object storage
49+
50+
In this learning path, OpenStack is deployed using **Kolla-Ansible**, which runs services as containers for easier management.
51+
52+
53+
## Use cases
54+
55+
OpenStack is widely used across industries:
56+
57+
* **Private Cloud Infrastructure:** Build internal cloud platforms
58+
* **Dev/Test Environments:** Rapid provisioning of virtual machines
59+
* **Edge Computing:** Lightweight deployments on Arm-based hardware
60+
* **Telco Cloud:** Network function virtualization (NFV)
61+
* **Research and HPC:** Scalable compute environments
62+
63+
