Essay Example on Cloud computing is the relatively new business Model

Module One Essay Introduction Cloud computing is the relatively new business model in the computing world According to the official NIST definition cloud computing is a model for enabling ubiquitous convenient on demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction 1 a Google Cloud Functions is a serverless execution environment for building and connecting cloud services Your Cloud Function is caused when an event being watched is excited Your code executes in a fully managed situation There is no need to provide any infrastructure or need not worry about managing any servers b Cloud Functions are written in many languages such as Javascript and execute in a Node js v6 11 5 environment on Google Cloud Platform We can run Cloud Function in any standard Node js runtime which makes both portability and local testing a breeze 2 a Infrastructure as a Service IaaS It enables users to provision processing network storage and other basic computing resources The user does not have control over the cloud infrastructure but has control over the operating systems applications and other storage components on the infrastructure End user application is delivered as a service rather than on premises software b Platform as a Service PaaS The user can deploy applications both user created and off the shelf applications on the cloud infrastructure 

The user has control only over the applications and not on the infrastructure operating systems servers and other storage components Application platform or middleware as a service on which development can be build and deployed of custom built applications c Software as a Service SaaS The consumer makes use of the applications deployed by the provider in the cloud infrastructure over a thin or think client The user cannot control the cloud operating systems servers or the applications although in certain cases the user is allowed to make changes to the configuration of the applications Compute storage or other IT infrastructure as a service rather than a dedicated capability 3 a There are four deployment models b Private cloud which solely works for one organization on a private network and is highly secured c Public cloud Which is own by the cloud service provider and offers the highest level of efficiency and shared resources d Hybrid cloud It is a combination of public and private deployment models Hydrid cloud specific resources are run or used in a public cloud and others are run or used on premises in a private cloud this provides increased efficiency cloud e Community Cloud This kind of specific community of consumers from organizations that have shared concerns e g mission security requirements policy and compliance considerations It may be owned managed and operated by one or more of the organizations in the community a third party or some combination of them and it may exist on or off premises f Nowadays many of the organizations have switched to the hybrid cloud function g Hybrid cloud is a combination of public and private cloud with an encrypted connection and technology which makes data portable 

One of the benefits of cloud services is that you can operate at scale and still remain secure It is similar to how you currently manage security but now you have new ways of delivering security solutions that address new areas of concern Cloud security does not change the approach on how to manage security from preventing to detective and corrective actions But it does however give you the ability to perform these activities in a more agile manner c Your data is secured within data centers and where some countries require data to be stored in their country choosing a provider that has multiple data centers across the world can help to achieve this d Data storage often includes certain compliance requirements especially when storing credit card numbers or health information Many cloud providers offer independent third party audit reports to attest that their internal process exist and are effective in managing the security within their facilities where you store your data References Cloud Functions Overview Cloud Functions Documentation Google Cloud Platform https cloud google com functions docs concepts overview The Top 3 Cloud Computing Service Models http focus forsythe com articles 559 The Top 3 Cloud Computing Service Models https www unitedsystemsok com solutions corporate corporate cloud computing services What is Cloud Security Amazon Web Services AWS https aws amazon com security introduction to cloud security
