Transcript of Cloud Computing
- is a strategy that talks about the sharing or access of computing resources(servers, software, storage) via the Internet that operates in a cloud server.
The term 'cloud' is taken as a
metaphor of the internet in a
paper published by MIT in 1996,
which talks about the idea
about cloud computing.
Where it all starts...
Intel was founded
- ARPANet is developing
into the Internet.
Intel engineer Ray Tomlinson wrote
a program that allowed users to
send messages from one computer
to another a.k.a The first E-mail
by Bill Gates and Paul Allen
John McCarthy introduced the
cloud computing concept

The Cloud continues to grow through network, laptops, computers, tablets, smart phones, and consoles. Many companies migrate their non-cloud applications in the cloud. Global access to the cloud became more and more popular.

Since ASP cannot accommodate the unique needs of their clients fast, a new way of service came.

Software as a Service
A photo that shows the evolution of file storage. Now in a single cloud. Posted by Windows on Facebook. (August 29, 2012)
You no longer have to buy expensive software licenses or programs. You don't need to add internal infrastructures because it can scale capacities in an instant. In cloud, you only pay for what you need under a subscription basis.
No need to worry for server overloads! Easy and instantly adjust server storage capacity to match up your demands. If client's demand is low, you can scale down the size of your cloud.
With a cloud, developers can commission servers at a low price via the Internet and have their application up and running quickly. Clouds can enable developers to do a lot more experimentation quickly and scale it up.

Good for both big and small businesses. Files
in the cloud are always backed up so you won't problem about disaster recovery.
Managed through contract
Cloud computing produce less carbon emissions from powerful machines.
"Data centers are responsible for two percent of the world’s greenhouse gas emissions." - Tuan C. Nguyen
Cloud computing contributes to a faster time to market. No need for long-term contracts because the services are already built-in in the system.
You can just concentrate on what you are working and ignore the updates, virus and disaster recoveries. They are already worked for you.

How do cloud send their services?
Most websites and server-based applications run on particular servers.
Deployment Models of Cloud Computing
High Maintenance Cost
Dependency over networks
Accessible anywhere provided that you will need Internet in order to access web-based applications.
Some says that cloud computing is a secret way of cutting down or controlling Internet resources. Others can access our files or even hack the database.
Cloud service providers may find it very costly in terms of fixing and updating the software, server, and platform.
Migrating from a different cloud server takes time same as transferring non-cloud applications.

- Work on your applications on both physical machine and switch to a virtual machine.
- provides the user with virtual infrastructure (memory, processor, and hardware), such as servers and data storage space.
- web hosting
Infrastructure as a Service (IaaS)
- provides the user to rent hardware, operating systems, storage and network capabilities to be used for application development.
Platform as a Service (PaaS)
- provides the user with access to already created applications that are operating in the cloud.
Software as a Service (SaaS)
- also called the middleware.
- develop applications using

To sum it up...
- Web-based applications such as google docs, photoshop express, Dropbox, and online operating systems like Cloudo.
- Storage or back-up
- Finance and accounting
- Enterprise cloud business
- E-mail services (GMail)
- Voice communication services like Skype
- Sharing of Photos and information
Cloud computing can be used for...
Dropbox is a web-based file hosting service, which uses cloud computing to enable users to store and share files and folders with others across the internet using file synchronization. It will automatically save your file synced to your phone, computer and the website by just dragging the files in your dropbox folder. Upgrading storage capacity can be done through invitations, offers, and upgrade.
Amazon S3 (Simple Storage Service) is an online storage web service offered by Amazon Web Services. The service uses a bucket where mostly any type of data may be stored. It is highly scalable and pay for only what you use. It is simple to use and retrieve amount of data anytime and anywhere on the web.
Windows Azure is an open cloud platform that enables you to quickly build, deploy and manage applications across a global network of Microsoft-managed data centers. You can build applications using any language, tool or framework.
- Emails and Online Documents
Even though our files in the cloud are kept externally, we are unsure if our files are being spied or hacked and at the same time very unaware of the location on where our files are being saved.
Relies on the service provider
Once the cloud server is down or close, people are very limited in accessing their files.
It allows you and your employees easy access on the cloud from different devices and places as long as you have internet connection.

This picture is taken from dropbox. An application that enables us to sync files in our devices by means of uploading automatically. You can see as of today that leading companies like Windows and Apple supports cloud applications. Many companies helped cloud computing more
popular than before.
- The hardware, software, and applications you're using may be anywhere up in the "cloud." As long as it all does what you want, you don't need to worry where it is or how it works.
Each type of
has its own server.
A cloud server needs twice the number of storage devices it requires to keep all its clients' information stored.
Applications work by the process of virtualization.
Virtualized applications are application that has everything (operating systems, server configuration, and infrastructure) it needs to run anywhere and anytime on capable devices that have an access to it. In terms of online cloud operating systems, they undergo hardware virtualization.
Applications in the cloud:
Applications / services in the cloud are sent under a virtual machine.

Digital Cloud Cards
Digital cards is a thin and mini device used for identity. Our personal information will be stored in a cloud server wherein we can access it anytime and anywhere with the use of 'digital cloud cards'. People can decide which information to show. We can register people as friends or cache their names in the cards so that we can remember them. Digital cloud cards can be used as long as you have load or Internet (Like timezone card). However, it can cause lots of connections that can affect network traffics.
With cloud computing, it is possible that cloud-enabled devices will be a client to access remote servers. Cloud servers will perform the computations through virtual machines and sends it to mobile devices. It will help the device save power and launch an application easily and fast. Cloud computing will increase devices capability in sharing information faster and secure. Text messaging through cloud may also be a future trend. Intelligent personal assistant like Siri will also be used more often because of cloud storage, which can store thousands of information. We will soon feel the real "Smartphone Era."

HISTORY OF CLOUD
The use of cloud file sharing becomes more popular. We can access and share files through a cloud. Cloud storage can be for one person, partners, groups or even an organization. It can be customized and its space is limited. Just like a USB, if we need more space, we will buy another one, but in the future, we will just upgrade our cloud and then additional space is given. We can access it anywhere (physical machine or mobile / devices) as long as we have permission to do. Files are backed up in an external hardware. Big and Small businesses will find it very helpful since they can store and upload files in the cloud and get it anytime. Students and teachers will also find this very helpful.
