Chapter 2 Readings: Cloud computing Introduction

Platform as a service(PaaS) provides a ______________ with __________, yet without ___________.

provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications — without the cost and complexity of buying and managing the underlying hardware, software, provisioning, and hosting.

Analytics in the cloud

provides the necessary hardware and algorithms needed to analyze and determine useful information from large amounts of collected big data. These analytical services focus on understanding, predicting, and influencing customer behavior both online and offline.

with cloud native software, Large applications are....

subdivided into a series of "microservies that can be tweaked with little effect on a running piece of software.

Regulations on the cloud include

the U.S. Health Insurance Portability and Accountability Act provide strict access and audit requirements for organizations storing personal health data. However it is unclear yet if cloud services will be in compliance with data and information regulations such as these.

Elastic resources, which Scale up or down quickly and easily to meet demand

the cloud uses ________ resources which.....

The Cloud native software approach stresses

the ease of use and low-impact alteration of components of any given software application.

how is the cloud a Metered service?

you only pay for what you use

how is the cloud a Self service?

All the IT resources you need are available with self-service access

private clouds are essentially ____________ that offer all benefits of ________ and also address ______________

Data centers that offer the benefits of public cloud and also address security and regulation concerns.

Cloud Pros

Productivity, collaboration, analytics, app development

App Development in the cloud

Cloud services such as Microsoft Azure offer services to host applications rather than developers being forced to host their applications with local servers that they would be forced to maintain themselves.

Collaboration in the cloud

Cloud software such as Jive allow for multiple different groups and organizations to work together in one online location, which allow for greater information sharing within an organization or project.

Software as a service (SaaS) are

Cloud-based applications — run on distant computers "in the cloud" that are owned and operated by others and that connect to users' computers via the internet and, usually, a web browser.

Cloud Cons

Cost, Reliability, Security, Regulation

How is the cloud changing organizations

changing how products are designed, decrease costs, making products easier to create, impacting management

Infrastructure as a service (IaaS) provides

companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis.

Productivity in the cloud

file sharing of important business information and data that is accessible via any web browser, this also cuts costs for travel.

Security concerns in cloud-based services include

firewall breaches, viruses, worms, and other malware. However many are also concerned that cloud hosting providers may steal company secrets, valuable information, or collected customer data. Controlling who is able to see what information even within the same organization is another concern for businesses using cloud services.

Organizations using public cloud systems can expect to have

great cost decreases over time which usually results in lower product pricing.

The Reliability of cloud-based services

has been called into question. Some believe that owning the local servers where data is stored is safer and enables business owners to have more control over the data they collect and manage.

The cost of using Cloud-based services

is a heavily debated topic. Although the economies of running and building a technology infrastructure will favor cloud services, the ability for cloud services to save businesses money is based entirely on the organizations size and overall use of technology.

The benefits of PaaS

1.)Develop applications and get to market faster 2.) Deploy new web applications to the cloud in minutes, 3.) Reduce complexity with middleware as a service

Public cloud systems use what kinds of apps?

1.)Innovative SaaS business apps for applications ranging from customer resource management (CRM) to transaction management and data analytics 2.)Flexible, scalable IaaS for storage and compute services on a moment's notice 3.)Powerful PaaS for cloud-based application development and deployment environments

The benefits of IaaS

1.)No need to invest in your own hardware 2.)Infrastructure scales on demand to support dynamic workloads 3.) Flexible, innovative services available on demand

The benefits of SaaS

1.)You can sign up and rapidly start using innovative business apps 2.)Apps and data are accessible from any connected computer 3.)No data is lost if your computer breaks, as data is in the cloud 4.) The service is able to dynamically scale to usage needs

Private clouds are built, owned, and maintained by

organizations.

Highly automated management of resource pools for everything from compute capability to storage, analytics, and middleware
