Today i will tell you worlds best 3 Computing Cloud Free Storage 
Here Are Following

  1. Drop Box
  2. Google Drive
  3. Apple iCloud

Drop Box:


Coming in at a close second, we have Dropbox, which is probably the most popular cloud storage solution on the web. With 2 GB of free space and 99$ a year for 50 GB it is again, reasonably priced. You can also get up to 16 GB of free storage from referring friends. It is a very simple service, and even someone computer illiterate could be using this in a few minutes. Dropbox is simple, pretty cheap, and overall a good choice.

Google Drive :

And the best cloud storage service out there in my opinion, is Google Drive. With 5 GB free storage 30$ a year for 20 GB and only 60$ for 100 GB Google Drive is the cheapest service on this list. It is also integrated with many other Google tools like Gmail, docs, and Google+, so if you use those Google drive will be even more useful. If you purchase more space, you will also get more storage on your Gmail account. If you use Google tools often, then this is definitely the best, and even if you don’t it’s still the cheapest.

3 Apple iCloud
If you are someone that owns many apple products, Apple iCloud might be the service for you. At 5 GB of free storage and 40$ a year for 20 GB, it’s reasonably priced. Apple iCloud is integrated with many iOS features and functions, so it would be extremely useful for someone with several apple products. There’s also a feature called iTunes match which will let you store non-iTunes music on iCloud for an additional fee. So, if you’re an apple user check out iCloud, if not, this probably isn't for you.

Cloud is a significant technological development and is being adopted by large enterprises as well as small businesses. Its adoption makes a lot of sense since it simplifies things and also makes them more secure at reasonable costs.
Google clouds one of the major options available and among the most well-known.
This is the first among a series of articles that we expect to write on Google cloud.

What is Google Cloud?

Google’s cloud platform provides reliable and highly scalable infrastructure for developers to build, test and deploy apps. It covers application, storage and computing services for back end, mobile and web solutions. More than four million apps trust and use the platform.
Google tries to keep the backend as simple as possible and uses a simple file system. This system is the foundation of the Google cloud platform. It handles requests for information via basic commands like write, read and open. It is a distributed system of computing.

The file system comprises of networks which are also known as clusters. One master server is allocated to each cluster. The system co-ordinates data requests through these master servers. Users’ actions get translated into data requests when they interact with the cloud and the information stored on it. Writing or formatting new data or other simpler actions like viewing a file are among these data requests.
The user’s computer sends data requests to other computers and acts like a client. The Google computer that has the data receives a message from the master server that takes the request. The computers that have the data are known as chunk servers. The information requested does not pass through a master server and is sent directly to the client from the chunk server.
It is a little complicated to make changes to data in the cloud since Google keeps a number of copies of every piece of data. A master server receives a write request, first of all. The server selects the chunk server that has the appropriate data. This is known as the primary chunk server replica. The client comes to know of the locations of all replica chunk servers through the master server.
When the user makes any changes, those get conveyed to the first replica chunk server that the user’s computer can connect to. Then, the change request travels through the system to all chunk server replicas, including the primary one. The primary chunk server makes the change and instructs all replicas to do the same.

For example, you can leverage Google cloud and the application programming interface (API) for MS Office to have several people edit a document at the same time. You can start saving files to the cloud after you install a plugin for the MS Office program suite. Everyone can then use and edit the cloud copy of the file, which becomes the master document. Google cloud assigns a unique URL to each file. However, the owner or creator of the document has to designate someone as an editor before they can download and start editing the file in MS Office.
If anyone makes changes to the document, the changes will be visible to all those the document is shared with. When many people make changes to the same content, Google cloud allows the document owner or creator to select the changes to keep.
Google cloud inserts metadata into a file, when it is uploaded to the service. This helps to identify the file and track changes across all copies. As the documents get synchronized to the master file, Google cloud updates all downloaded documents using metadata to update the right files.

Advantages of Google Cloud

  • Higher Productivity is gained through Quick Access to Innovation: Google’s systems can distribute updates efficiently and deliver functionality on a weekly basis or even faster.
  • Less Disruption is Caused When Users Adopt New Functionality: Rather than large disruptive batches of change, Google delivers manageable improvements in a continuous stream.
  • Employees Can Work From Anywhere: They can gain full access to information across devices from anywhere in the world through web based apps powered by Google cloud.
  • Google Cloud Allows Quick Collaboration: Many users can contribute to and access projects at the same time as data is stored on the cloud instead of their computers.
  • Customers are protected by Google’s Investments in Security: They are benefited by the process-based and physical security investments made by Google. Google hires the leading security experts in the world.
  • Less Data has to be stored on Vulnerable Devices: Minimal data is stored on computers that may get compromised, after a user stops using web based apps on the cloud.
  • Customers get Higher Uptime and Reliability: If a data center is not available for some reason, the system immediately falls back on the secondary center without any service interruption being visible to users.
  • Control and Flexibility Available to Users: They have control over technology and data and have ownership over their data in Google apps. If they decide not to use the service any more, they can get their data out of Google cloud.
  • Google’s Economies of Scale Let Customers Spend Less: Google minimizes overheads and consolidates a small number of server configurations. It manages these through an efficient ratio of people to computers.

Future of Google Cloud

Google’s approach and its entire strategy appears focused on the future and not the internet as it exists at present. Google seems to have placed its bet on the world having ubiquitous and low-cost internet access in the near future. This could include fast mobile broadband available globally and fiber connections in homes and offices.
Google seems to be building cloud for that kind of a world. It expects that by the time it refines its stack of apps, broadband will be available worldwide. It’s required as Google’s apps depend on internet connection and most of the data is stored on Google’s cloud servers.
However, the future of broadband may not be exactly in accordance with Google’s expectations. At many places, it is not financially viable to introduce high-speed internet access, solely on the basis of free market forces. This could remain true for a long time to come.
For Google’s vision to be realized, there will have to be greater competition in the bigger markets and more substantial private-public partnerships in smaller ones.

Our Cloud Load Balancer add fault tolerance and horizontal scalability to your systems by enabling you to balance traffic across a pool of Cloud Servers located across our two data centers.

When it comes to scaling up your web application on any Cloud, they’re an important piece of the puzzle so we’re continually optimizing and tuning them.
So today we’re announcing that we’re quadrupling their maximum capacity from 10,000 to 40,000 concurrent connections.
And due to some SSL acceleration improvements, they can now handle 1.4 Gbps of encrypted HTTPS traffic (or up to 1.8 Gbps of standard HTTP traffic).

HTTP request size configuration

We’ve also added a new config option to allow you to set the maximum buffer size for the HTTP request headers. The lower the buffer size, the less RAM is used, so the more concurrent connections you can support.
Some apps need large buffer sizes to handle very large cookies or lots of custom HTTP headers set by a CDN, whereas some don’t use cookies and can set a very low buffer size (a buffer size as low as 1024 bytes will actually get you up to 80,000 concurrent connections!)
So this allows you to customize your load balancer for your own specific requirements. The default is 4096 bytes, which allows 20,000 concurrent connections and should support the majority of use cases.

Upgrading

From today, all newly created load balancer have the new higher capacity. You can seamlessly upgrade your existing load balancer by creating new ones with the same settings and then remapping your Clouds ip.

At the base of IT’s challenges is a cycle where most of the budgets are consumed for maintenance of existing systems, thus leaving little for reinvestment and business growth. So more and more IT organizations are using cloud to unlock resources to encourage innovation.
However, while thinking of migrating critical and customer-facing applications to the cloud, organizations should carefully investigate delivery models and vendors before deciding to hire any.
1. Security: This is probably the most significant concern while considering a cloud partner. Since security requirements are different for different industries, complete understanding of the vendors’ security solutions is essential. You should examine vendors’ delivery models and architecture to judge their ability to provide end-to-end security. For instance, vendors providing private network solutions and dedicated private cloud are likely to prove more secure than those having shared infrastructure or a multi-tenant model.
2. Reliability: Reliability is an important criteria required to migrate critical applications to the cloud. The quality of the service along with service availability of core applications has to be ensured. You should have service-level agreements in place for appropriate data replication processes, along with core redundancy, geographically, for application failure. Speed-sensitive applications such as IP voice and CTI should have quality of service assured through the agreements.
3. Control: A degree of control is sacrificed when moving to cloud-based services. The degree of visibility and control of the solution platform is critical, along with the management of support services. You should be able to comprehend the vendor’s platform upgrade policies and maintenance windows and their impact on back-end integrations and service delivery. You should also be able to access the data required to make and manage good business decisions and maintain effectiveness of customer care initiatives and strategies.
4. New Technology Application: To increase their responsiveness, businesses try to complement the data centers they have internally with the cost-effectiveness and agility of a public cloud, which benefits from existing investments.
So, investigate the vendors’ experience in the application of new solutions and technologies, before deciding to hire any of them. The vendor should have an understanding of your customer care strategy and business needs and have the vision to introduce whatever new technologies are appropriate.
5. Relationship Fit: In spite of cloud providers trying to differentiate on the bases of distinct offerings based on cloud platform types, the cloud is often considered as uniform and single service. While commonalities are there, it is misleading to treat all offerings as similar. Therefore, you should carefully review the services provided by potential cloud partners and choose the one that will be the perfect fit.
The cloud partner should be able to provide expert insight into all needed to be done for the best results and have an in-depth understanding of your operations. It should be a full partnership rather than simply a relationship between a business and a vendor.
7. Responsiveness: From the first contact onwards, you can start gauging a potential partner’s responsiveness. It is better to know how responsive a cloud provider is before you partner with them rather than when already conducting business with them. For the purpose, you could examine testimonials, case studies, blogs, message boards and online reviews about your potential partner. These should help you to get a fair idea of what people are saying online about the service provider and, so, help you make the best possible decision regarding whether or not to partner with them.
7. Data Center Location and Safety: Along with man-made calamities, you should find out what your potential cloud service partner will do to protect your data against natural disasters such as flood and fire. A good vendor will always keep you updated about data center locations and any changes therein so that you have greater assurance about the safety and security of your data. The best, obviously, would be locations where the probability of natural disasters is relatively low, although no place can be completely secure in that respect.
8. Pricing: Reputed cloud service providers do not make large upfront costs a part of the equation. They allow you to pay only for what you need and pay-as-you-go, along with letting you expand or add services along with the passage of time and as the need arises for them.
9. Support: You should have technical support from your cloud service provider available 24×7 and that too from highly trained engineers, as against customer service representatives who provide only scripted responses.
10. Lost Data Recovery: Select a service provider that has systems and mechanisms in place to recover lost data in case you accidentally delete something. Reputable providers generally compensate clients in case of data loss due to any unfortunate occurrences.

Cloud computing is still relevant for use in small businesses and personal use. In this article I will try the premier provider of cloud computing services and to highlight briefly the advantages and disadvantages of each


Amazon EC2




Great service. It seems a bit ‘expensive for personal use at a glance. Seems cheaper solution (1.7 GB RAM memory, 160 GB hard drive, 1-1,2 GHz Xeon) of $ 75 a month, depending on traffic. If you compare the prices of VPS services in the medium and upper power range EC2 looks very interesting.

Advantages over ordinary VPS Services:

Great choice of operating systems and software “Also nginx, PHP a plus.” With great features such as Another important option is to create a special version just software and settings.
Almost immediately, creating and implementing server.
Storage flexibility and adaptation capacity. All preference settings in a separate file
Useful for testing and rapid control. Configuring the server takes only a few minutes – then you will be able to test the configuration you want to leave a day after I paid about $ first is not cool?
More RAM memory, hard drives and CPU


Cons:
Uncertainty of data storage on the local server storage. Server shutdown, hardware or software errors cause data loss. To avoid – to mode S3 (Simple Storage Service) so or insert your memory. This problem can be solved with Amazon EBS (Elastic Block Store)
The speed and performance of local memory and EBS are not transparent. Moreover, it is easy to understand the factors that affect stability.

Rackspace

Rackspace Cloud hosting service offers the use of cloud computing technology. In a nutshell, it is possible based on a server hosting network, which means that Rackspace can scale much more flexible, which means access VPS services are distributed. It can be compared to Amazon, but it can be considered a good alternative.

Benefits: The performance is very good and reliable, fast FTP seems to be more than 100Mbps. Static pages and DB connection is also very fast.
Management and control servers are well thought out and well designed.
Rackspace support staff known for their responsive support.

Cons:
Price
Rate list the availability of domain (if you have multiple domains)
If no wildcard SSL certificates

A recent global study of over 800 enterprise IT decision makers has found 1 in 5 organisations is ahead of the curve on cloud adoption and gaining competitive advantage over hesitant users.Firms are benefiting from the immediate advantages of cloud, such as the flexibility and agility that a cloud service brings in addition to cutting costs, whilst now driving business forwards and maximizing revenue opportunities.
The IBM study focused around the use of cloud computing platforms for big data analytic, collaboration and customer relationship management and seems to suggest that those firms are reporting nearly double the revenues and profit growth of those that are adopting a more cautious approach to the technology.


My question is this, why stop there?


Cloud has been around for a while now and this just further rubber stamps its application for business processes. The study goes on to say over 40% of respondents had realized major improvements in organisational efficiency too.









Cloud is providing these organisations with fantastic competitive advantage in several ways: strategy adaption, improved decision making and more comprehensive collaboration methodology. By removing the management costs in time and resource companies are seeing a marked improvement in other areas through a more direct focus. They have been able to develop services and create new revenue streams which furthers their advantage.


Cloud communications infrastructure is not something new, but it is something that organisations should be looking at very seriously. There really is no need now to keep these systems on premise, and in fact in some cases it can be extremely detrimental to do so.


Moving infrastructure for communications into data centers, unburdening technical teams and freeing resource to focus on other key tasks is proving to be a real business driver. The inflexibility of a static PBX on premise, the costs of ISDN VS IP/SIP infrastructure and the sheer complexity of configuring systems can now be realized , simply and effectively.


The IBM study should naturally be taken with a pinch of salt but it is a good indicator for the benefits of cloud. We have been focusing on cloud infrastructure for our customers for a number of years now, and are an accredited Professional Services Partner with VMware. We have been seeing great rewards for businesses willing to make that leap and be early adopters of what is increasingly becoming a normal practice for business, migrating their telecoms to the cloud.


What this has meant for us as an organisation is that we now understand the importance of a complete ICT picture and increasingly customers are pushing for full systems integration and a seamless transition across all services.

When talking about a cloud computing system, it's helpful to divide it into two sections: the front end and the back end. They connect to each other through a network, usually the Internet. The front end is the side the computer user, or client, sees. The back end is the "cloud" section of the system.
The front end includes the client's computer (or computer network) and the application required to access the cloud computing system. Not all cloud computing systems have the same user interface. Services like Web-based e-mail programs leverage existing Web browsers like Internet Explorer or Firefox.
Other systems have unique applications that provide network access to clients. On the back end of the system are the various computers, servers and data storage systems that create the "cloud" of computing services. In theory, a cloud computing system could include practically any computer program you can imagine, from data processing to video games. Usually, each application will have its own dedicated server.

A central server administers the system, monitoring traffic and client demands to ensure everything runs smoothly. It follows a set of rules called protocols and uses a special kind of software called middleAdvantages of Computer Clouds Middleware allows networked computers to communicate with each other. Most of the time, servers don't run at full capacity. That means there's unused processing power going to waste. It's possible to fool a physical server into thinking it's actually multiple servers, each running with its own independent operating system.
The technique is called server virtualization. By maximizing the output of individual servers, server virtualization reduces the need for more physical machines. If a cloud computing company has a lot of clients, there's likely to be a high demand for a lot of storage space. Some companies require hundreds of digital storage devices.
Cloud computing systems need at least twice the number of storage devices it requires to keep all its clients' information stored. That's because these devices, like all computers, occasionally break down. A cloud computing system must make a copy of all its clients' information and store it on other devices. The copies enable the central server to access backup machines to retrieve data that otherwise would be unreachable. Making copies of data as a backup is called redundancy.
