Once you have determined
that cloud computing will benefit your business, the next step is choosing the
right cloud model.
There are numerous options available and this part of the
process can be confusing.
In this blog, Myriad IT examines the key considerations
and attributes of the main models.
Control & customisation
Private cloud
With private cloud, the cloud is built and managed internally by the
company. Private cloud is sought after by companies requiring a
high degree of direct control over information and security.
Whilst private cloud offers the highest level
of control and customisation, it is not always necessary for an organisation to
invest in the establishment of a private cloud. A carefully selected 3rd
party vendor of public cloud may be able to meet
control, customisation and security requirements through public cloud.
Public cloud
With public cloud, cloud computing services are provided by 3rd
party vendors. Customers share data centre resources and access cloud services
via the Internet. Public cloud offers varying degrees of privacy and control
depending on the vendor.
There are 2 models for the provision of public cloud:
1.
Subscription style managed services
These feature pay-as-you go access to cloud services such as out of the box applications like ERP or CRM or packaged storage. It is common with this model that the provider takes ownership of data in the cloud and there is limited or no control over how services are provided. The advantage of these services are their relative simplicity and that users keep up with the latest features and functionality.
2. Tailored services
Some 3rd party public cloud
providers (such as Myriad IT), offer tailored data centre services with
logically separated infrastructure and no rights to data stored. This enables customers to utilise cloud
services for customised applications, tailor cloud computing services to meet
specific business needs and retain control of when and if upgrades, patches and
so forth are implemented.
Geographic location of data (within Australia)
The physical location of data may be an issue where:- Sovereignty of data is a requirement. For example many government organisations require that all data remain in Australia.
- Geographically distinct data centres may be advantageous for disaster recovery.
Security
We touched on security in our previous blog post. It is our view that most cloud vendors now have sophisticated security but poor implementation and configuration can leave unintended gaps in data or systems. Read the security blog post here.Myriad IT
