Making Stuff Better Through Making Stuff Better Through CloudstackCloudstackDeploying cloud-based phone systems
• IT Service Provider• Mobile, WAN, Telephony, Datacentres, Managed
Services• One of the UK’s largest Mitel Phone System
resellers
• Lead Data Analytics Team– Software Development– Monitoring & Data– IT Architecture
• Built our ACS platform in 2013• Areas of Interest
– Making things better through technology– Building great teams
• Member of the Data Analytics Team (joined in January)• Proud father of two• Ph.D. in Computer Science• Areas of interest
– Software Engineering– Security/Data Privacy– Automation/Integration– Scalability– System Architecture
• New to cloudstack
• Mitel licensing changes allowed for consumption-based usage
• Using a 3rd party to host cloud-based Mitel systems• Decided to host in-house• Needed to be VMWare• Existing Cloudstack platform was chosen
– more because we had high hopes for the possibilities rather than us actually knowing how we would do things
• Apache Cloudstack • (with support from Shape Blue)• VMWare ESXi (Xen too)• Brocade Switches• Netapp Storage• Mitel virtual appliances
– Custom Linux builds– Some Windows
• Our own MPLS network plus direct carrier integration
• VPC per customer• Or across two Zones for a resilient option• Up to 25 virtual machines across two Zones• SIP and WAN networks delivered to each VPC• 180+ firewall rules
• Hosted on traditional VMWare• Required lots of resource
– Network x2– Virtualisation– Mitel – PM
• Too many handoffs between teams• Manual builds• Too much TIME!
• API driven deployments• Simple UI for Mitel Engineers to do the (almost) full
deploy• Cut down on handoffs• Build in repeatability• Simplify the options
• Hosted on Cloudstack• Requires LESS resource
– Network x 1– Mitel
• Automated infrastructure builds (mostly)
• Automation of core network• Configuration of Mitel appliances• Replication• Modifications• Upgrades
• Fast• Consistent• Cost-effective (less people, faster)• Autonomy for the Mitel team• Driving Innovation
– Automation– Challenging existing thought processes
• Breaking down tech silos
• Written in PHP• Running against cloudstack 4.5• Based on: https://github.com/qpleple/cloudstack-php-client
code stats
integration tests
unit tests
• API-driven model is awesome• API documentation covers all API services and their
fields• Asynchronous calls• Resilient API service
• Use of identifier everywhere but for account• API-driven but it is getting messy
– Create a VM: 33 fields– List VMs: 62 fields (top level only)
• Documentation:– No definition of each type of field– individual APIs do not state whether they are async or not– Basic description per field (typos)
• We would still use cloudstack but …
• Handles the creation of most cloudstack components• Handles the dependencies among resources• Allows modifications of deployments
• Run as a daemon/service (cli application instead) • Manage:
– domains– accounts– users
• Report progress during a run (feed UI)
• Any Questions?
