Introduction to cloud computing terminology, concepts, and drivers.

1. sound like a cloud expert:
introduction to the cloud

2. Cloud terminology, concepts, and
drivers

3. Terminology & Concepts

4. A cloud: remotely provisioned IT
environment

5. Cloud computing: IT resource delivered
as a service over the internet

6. IT resources: software, hardware,
network, storage

7. SaaS: Software as a Service,
applications such as gmail or salesforce

8. IaaS: Infrastructure as a Service, for
example a server, data storage or network

9. PaaS: Platform as a Service, infrastructure
and software provided as tools to enable you
to create and host your own applications in
the cloud

10. On-Premise: IT resource hosted
conventionally (non cloud) within a
companies boundary

11. Cloud consumers: the user of a cloud
service

12. Cloud providers: the company
selling/providing a cloud service

13. Scaling: IT resource able to increase or
decrease usage on demand

14. Horizontal Scaling: increase or decrease of
the same type of resource, for example add
or remove a server, or add new user accounts
to gmail

15. Vertical Scaling: able to replace an existing
resource with a higher or lower spec for
example replace a 1 CPU server with a 2 CPU
server

16. Virtualization: software allowing a physical
IT resource to be shared by providing
multiple images of itself

17. Cluster: collection of independent (same
type) resources connected up to provide a
single system

18. Enabling technology: the technology witch
allows cloud computing to exists, for
example the key technologies of broadband,
and the internet

19. Cloud Drivers

20. Capacity planning, elastic on demand
professional technology allows for rapid
change and growth

21. Capacity planning: on demand instant
commissioning and releasing of services

22. Capacity planning: pay-as-you-go
services

23. Capacity planning: scalable services

24. Capacity planning: hence a reduced
need for resource planning

25. Cost, lower start-up costs allows capital
to be focused on the core business

26. Cost: lower initial capital cost outlay
(non purchase/ownership of the
resources)

27. Cost: lower ownership and
operational outlay (fewer, or no staff)

28. Availability and reliability, from the use
of well architected and reliable providers

29. Availability and reliability: pooled, clustered
and virtualised resources provide redundant
environments e.g. 99.9% uptime

30. Availability and reliability: rated providers
have extensive expert support

31. Do you now understand Gartners definition
of cloud computing? ‘a style of computing in
which scalable and elastic IT-enabled
capabilities are delivered as a service to
external customers using internet
technologies’

32. CTO ‘sound like an expert’ series are short
presentations introducing concepts and
issues of cloud computing – this is the first in
the series, introducing the high level
terminology and concepts. We hope you
enjoyed it.
