Technology - Cloud Flashcards
Overall cost of Curiosity
1 billion (over 7 years)
Curiosity target date
End 1H25
Cloud and climate change
By moving to the Cloud, we are addressing carbon emissions (like part of the energy that doesn’t go to computing but cooling) thanks to Azure which would have been major investments in Erding
Hardware in the Cloud
Cloud providers have extremely efficient processors that are proprietary. Same for network connections, etc. because the performances they require are beyond what exists today.
Same applies to MDW like AI
Erding and Disaster Recovery
DR was considered with a site in FRA but that would have cost us another Erding
Microsoft and L partnership: areas
- Cloud
- Collaboration
- Joint innovation
Example of MS and L collaboration
MS CEO helped convince Mariott or the Indian government
MS and L joint innovation
Both companies are obliged to invest a given amount for co-investment
Myth on “cloud-native”
!= running on the cloud
Putting a monolithic application in the cloud doesn’t make it cloud-native
Pillars of cloud-native (3)
1- Microservices
2- DevOps
3- Platform capabilities
Historic application design name
Tightly coupled monolithic applications
Why “tightly coupled” monolithic applications
Shared DB access and in-memory data
Intermediary application design name
Loosely coupled monolithic applications
Loosely coupled monolithic applications
Still deployed as a whole but internal modules are more independent
Microservices and engineering organisation
A microservice should be manageable by a single team
Answer to privacy needs on the Cloud
Zero Trust Architecture
CoD
Capacity on Demand
Cost of delays in Curiosity
150M eur (MS prices + ERD providers’ extension)
Total cost of move to the cloud
150M eur
L Cloud strategy wrt providers and why
A main one but several ones at some point
- not be tied
- in case not available in some countries
Example of multi-cloud providers for L
R-Box to remain on AWS & Google
Why is Cloud not cheaper
We didn’t work on elasticity out of lack of time
What is our migration to the Cloud technically and the steps
Like building a data centre in Azure (network, processes, etc.)
3 yrs to build the platform, 1 yr to move soft
Nats replaces
Kafka
Steps of Curiosity
PRD
Other TST systems
DR
3-6 mth stabilisation
