Our technical steps
1. Sizing + contract
2. IP planning
3. Migration methodology
4. Connect to the provider
5. Test migration
6. Selection pilot VM’s
7. Migration pilot VM’s
8. Evaluation
9. Migration Dev / Test / Acc VM’s
10.Migration Production VM’s Our current stage

The bears on the road we tackled
• Almost no early start-up problems;
• Pets to Pets migration -> low difficulty;
• Very positive feedback from the server
and application operators;
• Application operators are mainly
pleased with the big performance
increase;
• Excellent partnership with SURF.

What stays behind (on-premises)
•
•
•
•
IT operational monitoring systems;
Authentication and access;
CCTV;
Systems which we can’t migrate
because of legal or privacy reasons
(none so far).
10
Our next steps in IaaS
Offering the service directly to our
students and educators;
Back-up:
VM snapshots are part of the service;
Single item restore needed for some of our
SharePoint and SQL based services;
File services:
70TB which consist of 95%+ stale data;
We don’t want to migrate that to the cloud.
11
Our next steps in IaaS
Connect geo redundantly to the cloud;
Continue our automation (orchestration):
Connecting SCORCH to the CMP;
Using / migrating to hyper-scale cloud (MS
Azure / Amazon AWS):
Pets to cattle migration.

Next steps in the
SURFcumulus collaboration
A lot of possibilities;
The first steps to “Application Delivery As
A Service” or ADaaS are being taken.
