Lesson 3 Cloud Computing

The lesson 3 of ADET discussion focuses on cloud computing. 

For this discussion the lesson covered up to seven topic but only four discussed since the remaining was more specific on Amazon. 

1. Why Cloud Computing?

2. What is Cloud Computing?

3. Types of Cloud Computing

4. Cloud Providers

5. Lifecycle of a Cloud Computing Solution

6. Cloud Computing with AWS

7. Demo – AWS EC2 and AWS S3

For this discussion the lesson covered up to seven topic but only four discussed since the remaining was more specific on Amazon. 

On this topic our professor showed us the difference between on-premise and cloud computing and why it is prefer to use cloud computing ather than on-premise.

Here's a good example: On-premise doesn't have automatic update while cloud computing has a automatic software update. Although cloud computing are grate, it also has a cons, like if you lose internet connection you can't accessed to it and there was an issue about data privacy. Cloud computing is very usefull since we can use it at home because it can be access through internet.

Cloud computing is the on-demand online distribution of computing resources on a pay-as-you-go basis. Insteadof local storage with the help of cloud computing in will be able to save file on the internet. 

Two types of cloud computing

1. Deployment model - can either be save as a private cloud public cloud or hybrid cloud. By comparing this three on a transportation vehicle by our professor it make more easy to understand the difference between this 3 deployment model. Owning a private cloud which cause a higher price will give an access to that single person only while public cloud is the opposite and the hybrid cloud is the combination of both public and hybrid cloud

2. Service model - Cloud computing is offered in three different service models which each satisfy a unique set of business requirements. These three models are known as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). The professor explain the difference between PaaS, SaaS, IaaS using a baking a cake as an example

Lastly is the Cloude providers the common and mention by our professor are Amazon, Microsoft, IBM cloud, vmware Google cloud. This are some that manage and provide service for cloud computing.

Lesson 7 Web Application Design and Development

 The lesson 7 topic was all about Software Deployment.   Software deployment includes all of the steps, processes, and activities that are required to make a software system or update available to its intended users. Today, most IT organizations and software developers deploy software updates, patches and new applications with a combination of manual and automated processes. Some of the most common activities of software deployment include software release, installation, testing, deployment, and performance monitoring. Software deployment vs Software release So basically a  release  is a polished, tested version that is published, typically  with a  version number one greater than the last  release . To  deploy  means to push a new  release  to one or more machines, updating the current version. In web development, this means updating the version hosted on the production servers. note: even though a new version is release their...

Lesson 9 Javascript

  The lesson 9 topic was all about JavaScript contained 2 parts of the video. The first part was focused on knowing what is JavaScript. JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else.  There are lots of ways on using a JavaScript some example of this are mention in the video presented by our professor like detecting the browser used by a visitor at your page and manipulating cookies.

It helps your code be more readable to you and the browser, too. Most programming languages give commands to the computer. However, JavaScript commands the web browser.  Usually, programs contain many statements, which give instructions to the browser. In JavaScript programs,...

Lesson 6 Mobile Application Design and Development

 The lesson 6 topic was all about Mobile Application Design and Development.   Mobile technologies have transformed the way we live, work, learn, travel, shop, and stay connected. Not even the industrial revolution created such a swift and radical explosion in technological innovation and economic growth worldwide. Nearly all fundamental human pursuits have been touched, if not revolutionized, by mobile.  In June 29, 2007 the iPhone went sale and became fundamentally change the way people interact with phone because of it's interactive OS and design that are very convenient to the user.
