Openstack is a free, open standard cloud computing platform. It is deployed as an infrastructure-as-service in both public and private clouds where virtual servers and other resources are made available to users.
I love how Ubuntu puts it “Imagine a data centre with hundreds of physical machines, racked, powered and connected to each other. One tool turns this data centre into a cloud and enables on-demand resource provisioning through a self-service portal. That’s OpenStack “.
MicroStack is a micro cloud platform based on OpenStack. It is designed for small scale data centre deployments. It eliminates the complexity behind OpenStack. MicroStack answers the need for edge computing, providing reliable and secure cloud platforms.

Install OpenStack on Ubuntu 20.04
1. Run System updates
As the first step, we are going to run system updates. We need to update our repositories to make them up to date.
$ sudo apt update $ sudo apt upgrade -y
2. Install MicroStack
Next we will install MicroStack in our Ubuntu system with Snap. Open your terminal and run the following command to install MicroStack.
$ sudo snap install microstack --beta --devmode
You will get the following as the output
microstack (beta) ussuri from Canonical✓ installed
3. Initialized MicroStack
MicroStack can be initialized in either single or multinode mode. To initialize in a single node run the following command.
$ sudo microstack init --auto --control
This process will initialize many components including, RabitMQ, MYSQL, initializing TL certificate, configuring keystone, nova, etc.
This process will take some time to complete. so grab a cup of coffee as you wait to finish.

4. Launch an OpenStack instance
An instance is a virtual machine that runs inside the cloud. We are going to launch a VM with an image called cirrOS.
$ microstack launch cirros --name test
You will get the following output
Output Creating local "microstack" ssh key at /home/nextgentips/snap/microstack/common/.ssh/id_microstack Launching server ... Allocating floating ip ... Server test launched! (status is BUILD) Access it with `ssh -i /home/nextgentips/snap/microstack/common/.ssh/id_microstack firstname.lastname@example.org` You can also visit the OpenStack dashboard at https://10.20.20.1:443
Proceed to your favorite browser to launch the OpenStack dashboard
