- 4. OUR VALUES
- 10. A customer has contacted DIMSI to make a global analysis of their server compute usage. After a move to the cloud end 2020, they lost control on budget and are no longer able to a have clear overview of their expenses (iops, bandwidth, etc) The Project ❑ There is no devops process, and every comiter is free to define his own methodology ❑ They still have legacy hardware ❑ They now want to get control back on their usages and expenses
- 11. General informations ❖ Medium sized business in Paris (100 people) ❖ Digital Strategy consulting ❖ Existing hardware from 2013-2016 ❖ Moved their workload to public cloud between 2018 and 2020 Their Needs ✓ Keep costs under control ✓ Leverage existing Infrastructure ✓ Keep the same flexibility

- 15. Step 1 : Audit What are the customer cloud usage ? ▪ Microsoft Azure : Mainly serverless, Function As a Service How good is the on-premise infrastructure? ▪ 1G ISP bandwith ▪ 10G switches ▪ SSD and HDD storage arrays (QNAP 10 Gbe) ▪ IBM 3550 M5 with Intel Xeon E5 v4 Redundancy ?
- 17. Step 2 : Strategy Hybrid Strategy • Repatriate On Premise Poc, dev environment and non critical workload to reduce cloud hosting costs • Keep critical workloads, such as pre-prod and production that need geo clustering, high level of redundancy and scaling in Azure ▪ Use CloudStack for its IaaS capabilities to leverage the hardware ▪ Use same tech on cloud and on premise: Kubernetes with Azure functions / AWS Lambda ▪ Rely on the Cloudstack Kubernetes service
