1. Cloud 1.0.1
for SMEs_

2. º
Cloud Computing means to have
storage, resources or services
accessed through the Internet,
because they are not located
within the premises of my
organization.
Cloud
Computing_

3. º
A backup where data is uploaded from
my premises to the cloud. It is a good
solution when the data or apps are not
speed or bandwidth dependent.
Creating off-premises backups is a
safe way to protect critical data
against disasters.
WeTransfer, Drive, Dropbox or OneDrive
are Cloud Backups apps/services.

4. º
This service allows creating a work
environment where your
applications (email, documents,
other productivity apps…) can be
accessed anywhere, not only in your
office (or server).
Virtual Desktop adds availability,
flexibility and security.
DaaS (Virtual
Desktop)_

5. º
A contingency strategy for restoring
data where copies of your business
information are stored in the cloud.
It is a prevention measure that
allows restoring a backup if a
negative event happens.
Disaster
Recovery_

6. º
Elasticity is the capacity of my
system to adapt to changing
workloads in an autonomic
manner.
The cost in resources and
investment is thus closely
adjusted to requirements.
Elasticity_

7. º
Hosting is the capacity of an
undetermined number of
machines to act as one system.
Another type of hosting is when
several systems are hosted on one
machine.
Most websites require third party
hosting services.
Hosting_

8. º
A specific type of hosting where
physical space for servers is
rented out in a datacentre.
The datacentre provides a higher
degree of security, availability and
protected access to the customer.
Housing_

9. º
A combination of public and
private clouds.
It offers the best of both worlds: the
possibility of storing data locally
and being able to scale to a public
cloud model.
Hybrid Cloud_

10. º
IaaS (Infrastructure as a Service) is one of
the three basic models of cloud
computing along with PaaS (Platform)
and SaaS (Software).
In this model IT infrastructure (hardware,
storage and networking) is hosted and
managed by the cloud vendor.
IaaS_

11. º
Services that allow companies to
maximize cloud capabilities without
the need of having in-house cloud
experts.
Managed Cloud Services are brokered by
a service provider allowing companies to
focus 100% on their business.
Managed Cloud
Services_

12. º
An open cloud service or solution
uses open APIs and standards
(available for anyone).
It must allow portability between
cloud services and allow choosing
between different types of
infrastructure.
Open Cloud_

13. º
Platform-as-a-Service (PaaS) is a cloud
service category that provides a
platform and an OS environment
allowing me to develop apps and
access other online solutions.
PaaS services are stored in the cloud
and users access through a browser.
PaaS_

14. º
This billing method, also called
Pay-As-You-Go (PAYG), allows
companies to pay for the
computing and storage services
being used or allocated, instead of
the entire infrastructure that the
company may eventually need.
Pay as you use_

15. º
A private cloud is any cloud resource
that is only accessible by the
company where it is deployed.
The company can benefit from the
advantages of cloud architecture, but it
is also a burden for the IT department, it
is more expensive to maintain and
slower to deploy than the public cloud.
Private Cloud_

16. º
Public Cloud is a cloud service where IT
resources (servers, storage, applications)
are externally managed by a third
party service provider.
Its advantage is that it is quick to deploy,
scalable, and – in general – affordable.
However it is not exclusive to the
organization like a private cloud.
Public Cloud_

17. º
Reliability in cloud computing is the
capacity of a service to remain online
and available over time.
It is normally measured through the
Mean Time Between Failures (MTBF)
rate measured in hours, calculated as an
average of a service’s uptime between
failures.
Reliability_

18. º
It is a software deployment model
where a third party hosts the
applications providing online access to
end users.
These popular services can be accessed
through a browser, like Gmail, or through
software suites like Office 365.
SaaS_

19. º
It is the capacity of the cloud system
to grow or shrink in capacity in order
to meet changing business needs.
One of the main advantages of cloud
computing is to be able to upscale
systems quickly and effortlessly as
demand changes over time.
Scalability_

20. º
Virtual Servers on a Cloud
Platform where a client rents out
space and accesses remotely, in
contrast to physical servers.
What are the advantages?
Flexibility, scalability, security and
lower costs.
Cloud Servers_

21. º
A Service Level Agreement (or SLA) is a
contract where the cloud provider
and the end user agree of the details
of the service provided in measurable
terms: availability, uptime, or
redundancy, among others.
This contract warrants the cloud service
provided.
SLA_

22. º
A virtual storage model where
data is stored, managed and
backed up by third parties.
The client accesses this data
remotely through the Internet.
Cloud Storage_

23. º
A centralised repository of cloud
infrastructure services (such as
storage, bandwidth, etc.) specifically
designed to meet business demands.
It is also called a Software-defined data
centre (or SDDC).
Virtual Data
Centre_

24. º
A server that shares hardware and
software with other virtual servers,
opposed to dedicated servers. They are
a popular option for web hosting
because they provide resources quickly
and are cost-effective solutions.
