Landscape

The Cloud Landscape

7. Why cloud?
Because cloud enables self-service resource
provisioning, it gets your developers productive
faster and reduces time-to-market for application
development -- and progress.

11. Public Cloud vs
Private Cloud

12. Public cloud
A public cloud is ...
A collection of cloud resources accessible in a
general pool shared with other customers and
maintained by the public cloud provider.

13. Public Cloud
Advantages
1. No initial outlay
2. Instantly available
3. No management concerns
4. Various services (depending on the provider)

14. Public Cloud
Disadvantages
1. No centralized budget control
2. No cost control
3. Data security concerns
4. Data privacy concerns

15. Private cloud
A private cloud is ...
A collection of cloud resources accessible in a
general pool but kept within a single company,
either on premise or serviced by an external
company but isolated from other customer
workloads.

16. Private Cloud
Advantages
1. Centralized budget control
2. Data control
3. Architecture control
4. Access to legacy systems

17. Private Cloud
Disadvantages
1. Capacity limited by capital outlay
2. Inhouse maintenance requirements
3. Disaster recovery concerns

18. Hybrid Cloud

19. Hybrid cloud
A hybrid cloud is ...
... a collection of resources that may exist in
different cloud structures. Most often, some of
these resources are on premises for an
organization, and some are not. Workloads can
pass between these two (or more) sets of
resources.

20. Hybrid Cloud
Use cases
1. Dev/Test in the cloud
2. Alternate location for backup/disaster
recovery
3. Load bursting

21. Hybrid Cloud
Horizontal bursting
1. Apps and data begin internally.
2. Systems burst to public clouds when
necessary.
3. Loads recede to internal systems when
possible.

22. Hybrid Cloud
Vertical bursting
1. Apps are manually placed based on type.
2. Dev/test placed on external cloud until the
app is ready to be blessed.
3. Mission/business critical data/apps kept
internal.

23. Hybrid Cloud approaches
Datacenter as a Service
● Hosted externally
● Still isolated

24. Hybrid Cloud approaches
Homogenous cloud
● All OpenStack
● All the same APIs
How it works
at Rackspace

25. Hybrid Cloud approaches
Heterogeneous cloud
● Any type of cloud
● Any other type of cloud
>> ?

26. Summary

27. ● Cloud consists of several layers
● OpenStack is open source cloud
● Public cloud vs private cloud
● How hybrid cloud is about expanding capacity
● Hybrid cloud can take many forms
