PLATFORM
VMware vSphere to Apache CloudStack, fibre-channel storage, Veeam

Migration project with 24/7 L2/L3 engineers on watch and on call
VMs migrated, SLA never breached
New VM ready via API, from at least 6 hours
Downtime per VM, non-peak hours only
Every VM was built by hand. Each new VM on VMware took hours of manual work, including the software setup. The overhead grew with every customer, and the platform team could not keep pace with demand.
Move the platform, not just the VMs. We deployed Apache CloudStack with fibre-channel storage, built current OS templates and added a provisioning API. Existing VMs were migrated in place, with MAC addresses pinned so that no IP or network configuration had to change inside the operating systems.
Templates and an API turned a six-hour job into a seconds-long one.
No IP changes, SLA never breached. Pinned MAC addresses meant no network changes inside the operating systems. 24/7 L2/L3 engineers watched every operation live.
A SaaS platform on VMware with manual provisioning and growing overhead.
CloudStack with templates, a provisioning API and pinned MACs; VMs migrated in place, one at a time.
30+ VMs migrated, SLA never breached. New VMs ready in under 30 seconds. Client now has a control panel for CPU, memory, disk and IPv4 per project.
Self-service and an API for the client. The client creates its own clusters and VPN endpoints, deploys VMs through the API in under 30 seconds, and watches CPU, memory, disk and IPv4 allocation per project in a control panel. Backups are managed centrally with Veeam.
Tell us what you run. We will tell you how we would move it, and support it afterwards.
