ResiliencyResilient computing is a form of failover that distributes redundant implementations of IT resources across physical locations.

IT resources can be pre-configured so that if one becomes deficient, processing is automatically handed over to another redundant implementation.

Within cloud computing, the characteristic of resiliency can refer to redundant IT resources within the same cloud (but in different physical locations) or across multiple clouds.

Cloud consumers can increase both the reliability and availability of their applications by leveraging the resiliency of cloud-based IT resources.

Cloud provisioning is the allocation of a cloud provider's resources to a customer. 

Provisioning

When a cloud provider accepts a request from a customer, it must create the appropriate number of virtual machines (VMs) and allocate resources to support them. The process is conducted in several different ways: advance provisioning, dynamic provisioning and user self-provisioning.  In this context, the term Provisioning simply means " to provide." 

With advance provisioning, the customer contracts with the provider for services and the provider prepares the appropriate resources in advance of start of service. The customer is charged a flat fee or is billed on a monthly basis. 

Advance provisioning

With dynamic provisioning, the provider allocates more resources as they are needed and removes them when they are not. The customer is billed on a pay-per-use basis. When dynamic provisioning is used to create a hybrid cloud, it is sometimes referred to as cloud bursting. 

Dynamic provisioning andCloud bursting

With user self-provisioning (also known as cloud self-service), the customer purchases resources from the cloud provider through a web form, creating a customer account and paying for resources with a credit card. The provider's resources are available for customer use within hours, if not minutes. 

User self-provisioning

Hardware, software and digital assets can be managed from within the cloud. For example, suppliers offer the ability to view and manage your company's PCs - whether connected to your own internal network or not - and judge whether they're security compliant or need a software upgrade.

Asset management

MapReduce is a software framework that allows developers to write programs that process massive amounts of unstructured data in parallel across a distributed cluster of processors or stand-alone computers.

Concept of Map reduceMapReduce is a programming model introduced by Google for processing and generating large data sets on clusters of computers.

The MapReduce framework has two parts: A function called "Map," which allows

different points of the distributed cluster to distribute their work

A function called "Reduce," which is designed to reduce the final form of the clusters’ results into one output

The MapReduce framework is fault-tolerant because each node in the cluster is expected to report back periodically with completed work and status updates.

If a node remains silent for longer than the expected interval, a master node makes note and re-as

implementations of MapReduce are available in a variety of programming languages, including Java, C++, Python, Perl, Ruby, C# and C. signs the work to other nodes.

The business benefit of cloud governance is rather easy to define. It includes meshing the value of cloud governance with the value of leveraging cloud computing in general. Thus, this is a driver of the core benefits of cloud computing, including faster time to market, operational cost savings, the ability to expand elastically, and the ability to better secure and control your business assets.

Cloud Governance

As we move from simple, single cloud solutions, to complex multicloud implementations, the need for governance becomes much more apparent. Indeed, the tipping point of resources and services under management is easily reached, and processes and automated governance tools are required.

While the benefits of governance are clear, leveraging cloud governance requires some initial planning around the use of this technology, including understanding your own requirements and mapping them to the right cloud governance solution.
