Knowledge Byte: Provisioning Environments and Platform Services in Cloud

Provisioning can:

● Deliver a resource management system mechanism that enables cloud consumers to create, control, and customized ready-made environments.

● Deliver rapid platform provisioning capabilities for ready-made environments

Easy provisioning—Virtual or physical resources can be created, resized, and assigned to hosts in a fraction of the time it takes to provision manually. The environment is simpler to manage. The provisioning system takes care of all access control requirements.

Here are some of the key activities that happen during provisioning. The actual implementation varies from one cloud provider to the next, but the overall purpose is to ease and simplify the effort needed to make resources available to clients.

During provisioning, the following elements are selected:

● Software platform and development frameworks for ready-made environments.

● Common frontend or backend instances.

● High-availability options (failover, IT resource clustering).

● Monitors SLA metrics.

● Basic software configurations (operating system, pre-installed software for new virtual servers).

● IaaS resource instances from a number of available hardware-related configurations and options (processing capabilities, RAM, storage) hosted.

Platform services:

● Manual provisioning is inefficient and introduces unacceptable risks due to human error and inefficient response times in complex cloud deployments with multiple users.

● PaaS offers a selection of application development and deployment platforms accommodating different programming models, languages, and frameworks.

● Automated provisioning engines, scripts, and templates are used on-demand provisioning.
