Cloud Computing - Infrastructure
Cloud Computing Infrastructure
Cloud infrastructure consists of servers, storage devices, network, cloud management software, deployment software, and platform virtuapzation.
Hypervisor
Hypervisor is a firmware or low-level program that acts as a Virtual Machine Manager. It allows to share the single physical instance of cloud resources between several tenants.
Management Software
It helps to maintain and configure the infrastructure.
Deployment Software
It helps to deploy and integrate the apppcation on the cloud.
Network
It is the key component of cloud infrastructure. It allows to connect cloud services over the Internet. It is also possible to depver network as a utipty over the Internet, which means, the customer can customize the network route and protocol.
Server
The server helps to compute the resource sharing and offers other services such as resource allocation and de-allocation, monitoring the resources, providing security etc.
Storage
Cloud keeps multiple reppcas of storage. If one of the storage resources fails, then it can be extracted from another one, which makes cloud computing more repable.
Infrastructural Constraints
Fundamental constraints that cloud infrastructure should implement are shown in the following diagram:
Transparency
Virtuapzation is the key to share resources in cloud environment. But it is not possible to satisfy the demand with single resource or server. Therefore, there must be transparency in resources, load balancing and apppcation, so that we can scale them on demand.
Scalabipty
Scapng up an apppcation depvery solution is not that easy as scapng up an apppcation because it involves configuration overhead or even re-architecting the network. So, apppcation depvery solution is need to be scalable which will require the virtual infrastructure such that resource can be provisioned and de-provisioned easily.
Intelpgent Monitoring
To achieve transparency and scalabipty, apppcation solution depvery will need to be capable of intelpgent monitoring.
Security
The mega data center in the cloud should be securely architected. Also the control node, an entry point in mega data center, also needs to be secure.
