Cloud Computing An Emergent Distributed Database Platform

What is Cloud Computing

Types & Components Benefits Security Concerns Governance and Regulations Way Forward…

Cloud computing is a computing model, • where a large pool of systems are connected in private, public networks, to provide dynamically scalable infrastructure for application, data and file storage. • With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly.

Forrester defines cloud computing as: “A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end customer applications and billed by consumption”

Private Cloud Private clouds are built exclusively for a single enterprise-Just as an Intranet: • On-premise Private Cloud • Externally hosted Private Cloud

Hybrid Cloud Hybrid Clouds combine both public and private cloud models. With a Hybrid Cloud, service providers can utilize 3rd party Cloud Providers in a full or partial manner thus increasing the flexibility of computing.

Public Cloud Public clouds are owned and operated by third parties

SaaS – Software as a Service PaaS – Platform as a Service IaaS – Infrastructure as a Service

MaaS: Monitoring as a Service (MaaS) is at present still an emerging piece of the Cloud jigsaw but an integral one for the future. In the same way that businesses realized that their infrastructure and key applications required monitoring tools that would ensure the proactive elimination of any downtime risks, Monitoring as a Service provides the option to offload a large majority of those costs by having it run as a service as opposed to a fully invested in house tool. CaaS: Communication as a Service (CaaS), enables the consumer to utilize Enterprise level VoIP, VPNs, PBX and Unified Communications without the costly investment of purchasing, hosting and managing the infrastructure. XaaS: Finally XaaS or ‘anything as a service’ is the delivery of IT as a Service through hybrid Cloud computing and is a reference to either one or a combination of Software as a Service (SaaS), Infrastructure as a Service (IaaS), Platform as a Service (PaaS). communications as a service (CaaS) or monitoring as a service (Maas). XaaS is quickly emerging as a term that is being readily recognized as services that were previously separated on either private or public Clouds are becoming transparent and integrated.

Reduced Cost There are number of reasons to attribute Cloud technology with lower costs • The billing model is pay as per usage • The infrastructure is not purchased thus lowering maintenance • Initial expense and recurring expenses are much lower than traditional computing. Increased Storage With the massive Infrastructure that is offered by Cloud providers today: • Storage and maintenance of large volumes of data is a reality. • Sudden workload spikes are also managed effectively & efficiently, since the cloud can scale dynamically. Flexibility This is an extremely important characteristic. • With enterprises having to adapt, even more rapidly, to changing business conditions, speed to deliver is critical. • Cloud computing stresses on getting applications to market very quickly

Rise of Cloud Services: Cloud-based offerings from telecom operators and ICT providers will grow in future. Cloud Computing market size is expected to grow by $241B by 2020.

Definition of Information Security (CIA):

Confidentiality, integrity and availability, also known as the CIA triad, is a model designed to guide policies for information security within an organization.

(Ponemon): Cyber crimes continue to be very costly for organizations:  We found that the mean annualized cost for 58 benchmarked organizations is $15 million per year.  The net increase over six years in the cost of cyber crime is 82 percent

The cyber security industry faces a massive problem: There are simply not enough highly-skilled cyber security professionals. This is already a massive issue, but fast-forward to 2020 and the shortfall is expected to reach 1.5 million ◦ (2015 Global Information Security Workforce Study conducted by Frost and Sullivan).

The problem is twofold.  First, cyber security concerns now permeate our daily lives, and all organizations are aware of

cyber threats, Everyone is looking for experienced cyber security staff, and they want them now.

 The second part of the problem is that cyber security threats change at an astonishing rate.  Furthermore, as organizations begin to understand that cyber security is a business issue that

affects everyone in the organization, the scope of cyber security professionals’ roles are far broader.

 Once, they would have been entrusted to work with the IT team, implementing controls and

defenses that the rest of the organization was probably unaware of.

 Now it’s a top-to-bottom issue: it’s not just your cyber technology defenses, but the

processes you implement and the training you give all staff.
