Which are the different layers that define cloud architecture?
These layers are infrastructure, platform, software, and
an added layer of BPO (Business Process Outsourcing). The infrastructure layer
takes care of the hardware and the network. It introduces world-class
scalability and the technology of virtualization into cloud computing. For
this, an organization needs to build large data centers. But with the help of
IaaS, the hardware is virtualized and thus increases the capacity to support
Such cloud architecture layers allow the IaaS
vendor to use the computing resources to its 100% efficiency. Then another
layer i.e. platform provides all the resources to build applications. When
combined with IaaS it helps in developing, testing, running, and hosting
The software is the third layer wherein the user finds the consumption of the offering provided by the cloud service provider. At last, BPO is one of the most unique out of all the layers of cloud computing architecture as unlike other layers it is concerned with outsourcing the services.
the cloud system is equally important
The cloud architecture is composed of several
components that combine together to form different layers of cloud
architecture. Here are some of the important components that will make your understanding
of the cloud architecture more clear.
Cloud Subscriber- They are the actual users of SaaS, PaaS, IaaS models.
Brokers- Brokers are the front end or as an intermediary between the
cloud provider and the user who represents their interests in a standardized
Conceptualizer- Service conceptualizers are the ones who
develop the services for users or brokers at a fee.
Allocator- They act as a link between users and cloud
Provider- The pivotal role amongst all in the cloud
ecosystem is the cloud provider. E.g. are Microsoft, Google, etc.
Request Controller- Service request controller is the one that
allocates resources on a priority basis.
Pricer- After all the payment plans and requests are analyzed then
pricer does all the accounts work.
Monitor- The VM Monitor looks after all the virtual
