Bonsai Framework Infrastructure on the Cloud
Overview
This article is in progress and covers our first attempt at putting the Bonsai Framework infrastructure on the cloud. We have the following final targets,
Confluence with Supporting CICD Systems and Integration
Tomcat in Docker inside of LXD
Tomcat in Cloud Foundry inside of LXD
We have covered first set of steps on Path to Cloud (document later) up to CICD.
Using the in progress parts of the cloud article we have settled on the following,
Component | Selection | Notes | Top 3 Reasons |
|---|---|---|---|
|
|
|
|
... | Puppet |
|
|
Virtualization Cloud Provider | Azure | Will also try Amazon later for proper comparison. | Clearer documentation to start. |
Source Control for Code | Bitbucket selecting GitHub | DevOps Repository created with Frank as the main manager and Roderick as the Administrator. |
|
Distributed Operating System for Containers | None |
| Confluence is not yet. |
Operating Virtualization | LXD |
| Cost Savings, Transportable, Isolation. |
Virtualization Cloud Provider
Here details necessary to size with Azure Canadian Calculator.
Software Requirements
Ongoing systems that will always be up,

| 1.44GB |
|
Confluence | 1.6GB(to be tuned) |
| 10.79GB |

| 455.74MB |
|
Puppet Server |

Calculations
This was what I got as best bang for the buck given we can use LXD,
West US 2 is ~$20.00/month cheaper than other regions for what we need,
A1
Basic
1 Core
1.75 GB RAM
40 GB Disk
$21.71/month or $0.29/hour
Option A
Free Options
There are various free tiers on Azure of which we want to use,
Service Item | Sizing | Limits | Purpose |
|---|---|---|---|
Virtual Network |
| 50 free virtual network. | Create private networks with full control over IP addresses, DNS servers, security rules, and traffic flows. Virtual network to on-premises using a VPN tunnel, or connect using ExpressRoute service. |
Azure Active Directory |
| 500,000 directory objects and single sign-n for up to 10 apps per user. | Nice to have - can we make Confluence hook up with Google SSO? |
App Service | F1 Instance |
| Lab, try Tomcat and Docker. |
Scheduler |
| 3,600 job executions per month. | To run automated backups. |
Automation |
| 500 minutes per month of job run time. | IT automation. |
Azure Monitor |
| Free while in public preview |
|
Traffic Manager |
|
| DNS routing failover and basic traffic health check |
Monitoring Container Growth
