What is Cloud Computing?

Cloud storage is a cloud computing model in which data is stored on remote servers accessed from the internet, or “cloud.” It is maintained, operated and managed by a cloud storage service provider on a storage server that is built on virtualization techniques.

Benefits of Cloud Storage:
1. Flexibility

• Cloud Computing is a general term used to describe a new class of network-based computing that takes place over the Internet.
• Cloud computing is a synonym for distributed computing over a network and means the ability to run a program on many connected computers at the same time.
• These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very
• Simple graphical interface or Applications.
• Cloud Computing is the result of evolution and adoption of existing
• Technologies and paradigms.

TYPES OF CLOUD COMPUTING-

1. Public Cloud – Accessed by any subscriber with an internet connection and access to the cloud space.
2. Private Cloud – A private cloud is established for a specific group or organization.?
3. Community Cloud – Shared among two or more organizations that have similar cloud requirements.
4. Hybrid Cloud – A hybrid cloud is essentially a combination of at least two clouds.

CHOOSING A CLOUD PROVIDER-?

1. Software as a Service –A SaaS provider gives subscribers access to both resources and applications. Examples of SaaS include Google Apps, Casengo, TradeCard, Salesforce etc.
2. Platform as a Service -A PaaS provider gives subscribers access to the components. Examples of PaaS include Cloud Foundry, Force.com, Engine Yard, Mendix, and Google App Engine etc.
3. Infrastructure as a Service?It deals with primarily with computational infrastructure. Examples of IaaS include Google Compute Engine, HP Cloud, and ReadySpace etc.

ADVANTAGES OF CLOUD COMPUTING:?

• Lower computer costs:

You do not need a high-powered and high-priced computer to run cloud computing’s web-based applications.

• Improved performance:

With few large programs hogging your computer’s memory, you will see better performance from your PC.

• Reduced software costs:

Instead of purchasing expensive software applications, you can get most of what you need most cloud computing applications today, such as the Google Docs suite.

DISADVANTAGES:

• Requires a constant Internet connection
• Does not work well with low-speed connections
• Stored data might not be secure
• Stored data can be lost

Open Source Softwares

Whats is Open Source Softwares?

• Open source software(OSS) is computer software that is available in source code form.
• Open source software generally allows anyone to create modifications of the software, port it to new operating systems and processor architectures, share it with others or, in some cases, market it.
• A report by the Standish Group states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers

Definition:

Open source doesn’t just mean access to the source code. The distribution terms of open-source software must comply with the following criteria:

• Free Redistribution
• Source Code
• Derived Works
• Non-Discriminative
• Distribution of License
• Technology-Neutral
• Non-Restrictive

History:

• The free software movement was launched in 1983.
• The Open Source Initiative (OSI) was formed in February 1998 by Eric S. Raymond and Bruce Perens.
• The open source label came out of a strategy session held on April 7, 1998 in Palo Alto in reaction to Netscape’s January 1998 announcement of a source code release for Navigator (as Mozilla).

WiMAX Technology

What is WiMAX?

• WIMAX stands for Worldwide Interoperability for Microwave Access
•  I t is an IP based Wireless Broadband Access Technology utilizing IEEE 802.16e-2005 standard as the air interface.
• WiMAX, which will have a range of up to 31 miles, is primarily aimed at making broadband network access widely .
• User can expect to have broadband access speeds ranging from 256 Kbps to 2 Mbps.
• WiMAX is most suitable for home users, individual, small office and home office. Customer who want to use internet at home and in the office but want to subscribe only one connection can use this facility. Customer for those who have no phone line at the location and / or live in the rented apartments can also use WiMAX Connection.

NET Technology:

Broadband access is too expensive and WiFi coverage is very sparse.

WiMAX will provide broadband connectivity anywhere, anytime, for any device and on any network.

High speed internet access where it is currently unavailable.

Substantially increase data speeds for applications like Online Gaming, Streaming Video and Video Conferencing.

• The new technology promises
• High speed of broadband service
• Wireless rather than wired access
• Broad Coverage

WiMAX consist of-

• A WiMAX tower, similar in concept to a cell-phone tower – A single WiMAX tower can provide coverage to a very large area as big as 3,000 square miles (~8,000 square km).

• A WiMAX receiver – The receiver and antenna could be a small box or Personal Computer Memory card, or they could be built into a laptop the way WiFi access is today
• 

How WiMAX Works-

Benefits of WiMAX-

Speed-

• Faster than broadband service

Wireless-

• Not having to lay cables reduces cost
• Easier to extend to suburban and rural areas

Broad Coverage-

• Much wider coverage than WiFi hotspots.

Advantages of WiMAX-

• Single station can serve hundreds of users.
• Speed of 10 Mbps at 10 kilometers with line-of-site.
• It is standardized, and same frequency equipment should work together.
• providing portable connectivity , and also provide data and                                                             telecommunication services.

Convenience: You can move around the CPE(customer premise equipment) device and get the Internet access everywhere in your home, and in the office. And you can subscribe only one connection for both office and home use.

Direct Attach Storage (DAS)

Introduction:

DAS is a type of storage that is connected directly to the server which enables quick access to the data but only through the server.

Direct-attached storage (DAS) is a basic level storage in which the host computer holds the storage devices or these can be connected to one server at a time. Networked workstations can access the data only through the host. DAS was the first storage model that gained widespread acceptance and is widely used. Even though networked storage models are gaining popularity, DAS still finds takers because it is easy to deploy and has a low initial cost of deployment. It helps if you have an idea of what your data availability needs are at present and what they will be in the future.

Storage System:

DAS is the most basic storage subsystem that provides block-level storage, and it’s the building block for SAN and NAS. The performance of a SAN or NAS is ultimately dictated by the performance of the underlying DAS, and DAS will always offer the highest performance levels because it’s directly connected to the host computer’s storage interface. DAS is limited to a particular host and can’t be used by any other computer unless it’s presented to other computers over a specialized network called a SAN or a data network as a NAS server.

There are the three basic types of storage.

• Direct Attached Storage (DAS),
• Storage Area Network (SAN),
• Network Attached Storage (NAS)

DAS is the basic building block in a storage system, and it can be employed directly or indirectly when used inside SAN and NAS systems. NAS is the highest layer of storage and can be built on top of a SAN or DAS storage system. SAN is somewhere between a DAS and a NAS.

SCSI — Small computer system interface is one of the oldest forms of storage interfaces traditionally used in server or workstation class computers.

PATA — Parallel advanced technology attachment (originally called ATA and sometimes known as IDE or ATAPI) was the most dominant desktop computer storage interface from the late 1980s until recently, when the SATA interface took over.

SATA — Serial advanced technology attachment is the official successor to PATA. So far, there have been two basic versions of SATA, with SATA-150 and SATA-300.

SAS — Serial Attached SCSI is the latest storage interface that’s gaining dominance in the server and storage market. SAS can be seen as a merged SCSI and SATA interface, since it still uses SCSI commands yet it is pin-compatible with SATA.

FC — Fibre channel is both a direct connect storage interface used on hard drives and a SAN technology. FC offers speeds of 100, 200, and 400 MB/s.

Flash — Flash memory isn’t a storage interface, but it is used for very high-end storage applications because it doesn’t have the mechanical latency issues of hard drives.

RAM — Random access memory is also not traditionally seen as a storage medium, but it can be used as an ultra-fast storage device.

Benefits:

• The key difference between Direct Attached Storage (DAS) and NAS is that DAS is simply an extension to an existing server and is not networked while NAS sits on a network as its own entity; it is easier to share files with NAS.
• Availability of data might potentially be increased . if it provides built-in RAID & Clustering capabilities.

Limitations:

• Not suitable for data intensive applications.
• Low data transfer rate.
• Limited scalability.
• Highly initial cost.

• A surface computing platform from Microsoft.
• Project began in 2001 Introduced in 2007.
• Combination of software & hardware.
• We can also call it table top.

“Microsoft Surface represents a fundamental change in the way we interact with digital content. With Surface, we can actually grab data with our hands, and move it 360o, information between objects with natural gestures and touch. Surface features a 30-inch tabletop display whose unique abilities allow for several people to work independently or simultaneously. All without using a mouse or a keyboard.”

API of MS Surface:

The Surface Experience:

There are many features of windows surface some of the specials features ,i am showing here-

Direct Interaction-User can “grab” items with their hands and move data to different location on the hard disk or to removable devices. Easy touch navigation-without the use of a mouse and keyboard.

Object Recognition-Users can place physical objects such as drinks, cell phones, cameras, wines, food,laptops,mp3 players on the table to activate digital responses. And to see contents.

Multi-Touch Friendly-Recognizes several points of contact simultaneously as opposed to average single point of contact touch screens. Gives users the ability to be completing unrelated tasks simultaneously.

Multi-USer-Friendly- It’s design multi-touch capabilities make it a great gathering spot to share data, exchange ideas, and inspire group collaboration.

Internal Specification:

1)Screen: The Surface has an acrylic table top which a diff user makes capable of processing multiple inputs from multiple users. Objects can also be recognized by their shapes or reading.

2) Infrared: Infrared light is projected onto the underside of the diff user. Objects or fingers are visible through the diff user by series of infrared-sensitive cameras which are positioned underneath the surface of the tabletop.

3) CPU: This is similar to a regular desktop. The underlying operating system is a modified version of Microsoft Vista.

4) Projector: The Surface uses the same DLP light engine in many rear-projection tvs.

5) Cameras: 4 infrared cameras place inside the tabletop and that focus on screen and reads user interaction from four side and cover the whole screen.

Technical Specification:

Software platform: Microsoft Surface 1.0

Display + vision input technology: Rear projection DLP

Weight: 198 lbs (90 kg)

Physical dimensions (L x W x H): 42.5 x 27 x 21 in (108 x 68.6 x 53.3 cm)

Networking: Wi-Fi, Bluetooth, and Ethernet.

Operating system: enhanced windows vista (32-bit)

Price: starting 10,000 us $ (approx 5 lakh in INR)

How Does it works:

Digital Light processing is a technology used in newer Surface devices.

It allows recognition of fingers, hands, and objects that are placed on the screen, enabling vision-based interaction. Sensors in the individual pixels in the display register what is touching the screen.

A step-by-step look at how Pixel Sense works:

* When An object is placed on the display.

* An infrared back light illuminates the object.

* Light reflected back from the object is registered by cameras.

* Values reported from all of the cameras are used to create a picture of what is

on the display.

* The picture is analyzed using image processing techniques creating a

corrected image.

* The corrected sensor image and information about the objects placed on the

display are sent to the PC.

* And then surface system react according to the user requirement.

Hadoop Technology

Introduction:-

       Hadoop is a new technology. Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. It provides massive storage for any kind of data, processing power and the ability to handle virtually limitless concurrent tasks or jobs.

History:-

        As the World Wide Web grew in the late 1900s and early 2000s, search engines and indexes were created to help locate relevant information amid the text-based content. In the early years, search results were returned by humans. But as the web grew from millions of pages, automation was needed.

Why is Hadoop important?

• Ability to store and process huge amounts of any kind of data, quickly. With data volumes and varieties constantly increasing.
• Computing power.
• Fault tolerance.
• Flexibility.
• Low cost. The open-source framework is free and uses commodity hardware to store large quantities of data.
• Scalability. You can easily grow your system to handle more data simply by adding nodes. Little administration is required.

What are the challenges of using Hadoop?

• MapReduce programming is not a good match for all problems.
• There’s a widely acknowledged talent gap.
• Data security– it is also provide data security for hadoop and big data users.
• Full-fledged data management and governance. Hadoop does not have easy-to-use, full-feature tools for data management, data cleansing, governance and metadata.

How Is Hadoop Being Used?

• low-cost storage and data archive.

  

• Sandbox for discovery and analysis.
• Data Lake.
• Complement your data warehouse.

What is Big Data?

Introduction:

            Big data is a term that describes the large volume of data ` both structured and unstructured ` that inundates a business on a day-to-day basis. But it’s not the amount of data that’s important. It’s what organizations do with the data that matters. Big data can be analyzed for insights that lead to better decisions and strategic business moves for any organizations or company.

History:

            While the term “big data” is relatively new, the act of gathering and storing large amounts of information for eventual analysis is ages old. The concept gained momentum in the early 2000s when industry analyst Doug Laney articulated the now-mainstream definition of big data as the three Vs:

1. Volume:-Organizations collect data from a variety of sources, including business transactions, social media and information from sensor or machine-to-machine data.
2. Velocity:-Data streams in at an unprecedented speed and must be dealt with in a timely manner.
3. Variety:-Data comes in all types of formats ` from structured, numeric data in traditional databases to unstructured text documents, email, video, audio, stock ticker data and financial transactions.

Why Big Data important?

The importance of big data doesn’t revolve around how much data you have, but what you do with it. You can take data from any source and analyze it to find answers that enable 1) cost reductions, 2) time reductions, 3) new product development and optimized offerings, and 4) smart decision making. When you combine big data with high-powered analytic, you can accomplish business-related tasks such as:

• Determining root causes of failures, issues and defects in near-real time.
• Generating coupons at the point of sale based on the customer’s buying habits.
• Recalculating entire risk portfolios in minutes.
• Detecting fraudulent behavior before it affects your organization

Who uses Big Data?

Today’s life we have large amount of information to gathering and storing but that doesn’t matter how much amount of data you have.

Below points shows where big data is important-

• Education
• Government
• Healthcare
• Banking
• Manufacturing
• Retail etc.
