4. The Cloud Is About Self-Responsibility
Independent from the use case!
“Everything fails, all the time”
Werner Vogels, CTO Amazon.com
Think about your requirements
and challenges!
Discuss what is your job if
you use the cloud!
An IaaS (public) cloud provider „just“ delivers the resources for
building your own virtual, flexible, high scalable and high
available datacenter on an on demand and pay per use base.

Even if the underlying infrastructure fails, is removed or
replaced, your applications should continue to function!

7. Multivendor Cloud Strategy
✔
Develop fallback scenarios to prevent an outage
✔
Use all Regions and Availability Zones of a
cloud provider
✔
Use the infrastructure of more than one
cloud provider
✔
Build software which supports a
multivendor strategy
✔
Use a mirrored infrastructure that runs
parallel or starts during a failure at the [5]
primary provider
✔
Better: use the infrastructure of more than one vendor in parallel
✔
Distribute your services/ instances over several providers
