Cloud Computing

1. a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources ~ (Networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

 

configurable : 설정(변경) 가능한

provisioned : 충분히 제공된

 

Examples of computing resources include :

 

- networks

- servers

- storage

- applications

- services

 

5 Essential characteristics

 

1. On-demand Self-service

   you get access to cloud resources such as the processing power, storage, and network you need, using a simple interface, without requiring human interaction with each service provider.

 

2. Broad Network Access

   cloud computing resources can be accessed via the network through standard mechanisms and platforms such as mobile phones, tablets, laptops, and workstations.

 

3. Resource Pooling

    what gives cloud providers economies of scale, which they pass on to their customers, making cloud cost-efficient.

    Resources dynamically assigned based on demand

 

4. Rapid Elasticity

   you can access more resources when you need them, and scale back when you don't.

 

5. Measured Service

   you only pay for what you use or reserve as you go.

   Resource usage is monitored, measured, and reported transparently based on utilization.

 

elasticity : 탄성, 탄력성

mechanism : 1. (기계 내에서 과업을 수행하는 부분인) 기계 장치[기구] 2. 목적을 달성하기 위한) 방법, 메카니즘

tenant : 1. 세입자, 임차인, 소작인

pool : (공동으로 이용할 자금정보 등을) 모으다

transparently :  투명하게, 솔직하게

utilization :  이용, 활용

agile : 1. 날렵한, 민첩한 (=nimble) 2. (생각이) 재빠른, 기민한

 

3 Types of cloud deployment models

 

(1) Public

    leverage cloud services over the open internet on hardware owned by the cloud provider, but its usage is shared by other companies.

 

(2) Private

    the cloud infrastructure is provisioned for exclusive use by a single organization. It could run on-premises or it could be owned, managed, and operated by a service provider.

 

(3) Hybrid

     mix of both public and private clouds, working together seamlessly

 

leverage : 1. 영향력 2. 지렛대 사용, 지렛대의 힘

~ 레버리지 효과 : 경제 기업이나 개인 사업자가 차입금 등 타인의 자본을 지렛대처럼 이용하여 자기 자본의 이익률을 높이는 일.

infrastructure : 사회[공공] 기반 시설

provisioned : 충분히 제공된

provision : 1. 공급, 제공 2. 대비, 준비 3. (특히 특정 기간 동안 필요한 식량을) 공급하다

seamlessly : 이음매가 없이, 균일하게

 

3 service models

three layers in a computing stack : Application(SaaS), Platform(Paas), Infrastructure(IaaS)

Three cloud computing models are aptly referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)

 

In Infrastructure as a Service (IaaS) Model, you get access to infrastructure and physical computing resources such as servers, networking, storage, and data center space - without the need to manage or operate them.

 

In a Platform as a Service(Paas) model, you get access to the platform, that is the hardware and software tools, usually those needed to develop and deploy applications to users over the Internet.

 

Software as a Service is a software licensing and delivery model in which software and applications are centrally hosted and licensed on a subscription basis, and sometimes also referred to as "on-demand software".

Reading: Module 1 Summary

In this module, you have learned:

●       Cloud computing is the delivery of on-demand computing resources over the internet on a pay-as-you-go basis; resources are dynamically assigned and reassigned among multiple users and scale up and down in response to users’ needs.

●       The origins of cloud computing can be traced back to the mainframes of the 1950s, with virtualization technologies and hypervisors serving as catalysts for the emergence of modern-day cloud computing.

●       Organizations must consider their business needs, investment viability, and risk capacity in order to create a cloud adoption strategy that delivers desired benefits without causing business disruptions and security, compliance, or performance issues.

●       Cloud adoption is growing faster than predicted. Driving this technological wave are cloud service providers with a host of services ranging from Infrastructure, Platform, and Software services. Some major Cloud providers of our times include AWS, Alibaba Cloud, Google, IBM Cloud, and Microsoft Azure.
