Cloud Virtualization



Cloud Management

“Cloud management means thesoftware and technologies designedfor operating and monitoringapplications, data and servicesresiding in the cloud. Cloudmanagement tools help ensure acompany's cloud computing-basedresources are working optimally andproperly interacting with users andother services [1]”

Typically it involves with varioustask. Listed below-

Performance monitoring likeresponse time, latency anduptime.

And initiating and overseeing ofdisaster recovery andcontingency plans

CLOUD MANAGEMENT

Under cloud management following

are the key playing actor-Resiliency

Provisioning

Asset Management

Map Reduce

Cloud Governance

High Availability and Disaster Mgmt


Resiliency

According to [thefreedictionary.com],

Resiliency means an occurrence of rebounding or springing back.

Or

the physical property of a materialthat can return to its original shapeor position after deformation thatdoes not exceed its elastic limit.


The Power of Thinking

According to technical white paper [2] ofcloud computing-Cloud Resiliency –“One big advantage that all types ofcloud computing offer is that, by itsnature, cloud computing removes singlepoints of failure. The failure of one nodeof the system has no impact oninformation availability and does notresult in perceivable downtime. Cloudcomputing provides a highly resilientcomputing environment. The one majorweak point is the network itself. If thisfails, then cloud computing fails. It istherefore essential that cloud suppliersand private cloud developers considernetwork topology and ensureredundancy is built into the entirenetwork.”


Cloud resiliency is the ability of a datacenter and its components -- servers,storage, etc. -- to continue operating in thewake of some kind of disruption, whetherit's a breakdown of equipment, a poweroutage or even a natural disaster.

[Christopher Nerney]

Microsoft Perspective……Resiliency

According to Microsoft surveyed [3] …

“Software development has traditionallyemphasized fault prevention, and becausecustomers

operated the software, any failures wereisolated to customers’ on-premisesdeployments.”

While ..“cloud services typically run as

highly complex, distributed,“always available” systemsthat serve many customers.Cloud systems are globallydistributed, often built usingcommodity hardware, andhave inherent dependencieson third-party and partnerservices. The nature of theInternet and globalnetworking is that transientand even prolonged failuresare quite common.”



So engineers need to make anecessary mind shift to adoptRecovery-Oriented Computing(ROC) practices, fully embrace theidea that failures will happen, andtherefore incorporate copingstrategies into their service designand software to minimize theharmful effects of such failures




Phases of RMA –

It has 4 phases:

1. Pre-work – Creates a diagram tocapture resources, dependencies,and component interactions.

2. Discover - Identifies failures andresilience gaps

3. Rate - Performs impact analysis

4. Act - Produces work items toimprove resilience
