The company that offers the service maintains and runs the server which can contain thousands of such networks. The general idea is that the user gets the control he would have over a local area network without having all the equipment he would need to run a wide area network. Users can setup network drives and copy files just as they could from any other network. The concept of a web drive provided by services such as Host Gator is similar.
The primary advantage of cloud computing is the small user is that he does not have to worry about where the other people in the cloud actually are. The company sets it up so that the underlying software runs over the TCP/IP protocol. The users just need a way of connecting to the Internet, which can include mobile devices such as the user’s cell phone.
Because cloud computing is offered as a service, a person must pay a monthly plan for the convenience. The overall price for the service is generally less than the cost of updating routers
The software world constantly changing and evolving. When Salesforce debuted in 1999, it was the first company to offer commercial service applications from a normal web site, what the market over time, called Cloud Computing. Since then, Salesforce has been a pioneer in cloud technology for companies both large and small.
Simply put, cloud computing is computing that leverages the connectivity and Internet mega scale. Cloud computing democratizes access to software capabilities first level, as a software application provides service to multiple clients. The multiuser environment is a key difference cloud computing simple outsourcing or older model application service provider architectural distinction. Now, small businesses can take advantage of the power of great technologies in a way that allows them to expand. Cloud Computing offers individuals and businesses of all sizes the power of a well-maintained set of computing resources, safe, easily accessible and On Demand, such as servers, storage, and data and application software. It also provides companies greater flexibility with their data and information, which can be accessed at any time and from anywhere. This is key for companies with offices around the world or different work environments, including remote locations. And thanks to minimal management, it is possible to expand all elements of cloud computing software upon request. All you need is an Internet connection.
Cloud Computing How does it work?
Clouds using a network layer for connecting devices endpoint users, such as computers or smartphones (along with a growing variety of non-traditional devices such as the “portable”), a centralized resource center data. Before the cloud, companies providing services could only run software reliably if they could also pay the bill to maintain the necessary infrastructure servers. Moreover, often, the traditional software required hiring or outsourcing a full team of professionals to address the inevitable parade of errors, service issues and updates. Cloud Computing concept gets rid of all these problems and outdated requirements.
Cloud Computing: why it is time to change
The Cloud Computing (and its potential to change the way we use the equipment) has been on the minds of leaders in technology for years. This is what Steve Jobs said on the subject in 1997:
“I do not need a hard drive on my computer if I can get quickly to server … walk wearing these teams is not connected Byzantine compared”.
At that time, the idea of using remote servers looked more like a crazy dream; most people accessed the Internet using 56K modems. However, with fiber optic networks and high-speed Internet freely available at reasonable prices, the idea became reality.
Today, the market for Cloud Computing generates about 100 billion dollars a year. It is estimated that 42% of decision makers plan to increase IT spending on cloud computing in 2015 with the fastest growing companies with more than 1,000 employees (52%). These are the reasons why you should consider the change:
To get rid of the hardware
So why try to adopt this technological breakthrough? For starters, the Cloud Computing hardware removes from consideration of the company.
When a company provides its own software, servers must address. These servers require exclusive supply energy and replacement parts. You also need to configure and monitor if they have performance problems and require experts on call to fix them.
When the software is cloud-based, infrastructure costs and potentially fluctuating costs and worries disappear. Instead, these costs are integrated from the start. Cloud Computing provider is responsible for solving all headaches. It is your job to ensure a homogeneous process without cuts in exchange for a fixed cost reasonable for the software.
To achieve greater security
Cloud computing can also be extremely safe and often exceed safety levels of traditional computing. Cloud computing allows companies to attract and retain cybersecurity higher quality staff (compared to IT employees on site). It also allows implement the latest technologies and practices, with the help of a broader view of patterns of global threats that even available for most national governments. With tens or even hundreds of users potentially at risk of exposure to malicious programs, keeping organizations safe can be costly. Cloud Computing providers work with a much larger (and, as they need to protect all its customers, each company benefits from the larger group) budget, which means a higher level of security for all.
With a solid infrastructure, diligent monitoring and security protocols in place, cloud computing can provide small and medium businesses the same protection that companies with the highest requirements.
To unify the level of computer
Cloud Computing has the ability to put everyone on the same level. No matter if you have hundreds of thousands of users of the platform. Cloud computing democratizes application software company. With elasticity to increase or decrease the rate of a whole quickly (and sometimes automatically) client, the end user generally does not need to know what happens in the cloud. All you need to do is log on and deal with a necessary task.
central features of Cloud Computing
On Demand: no need to consult other person or engage a professional IT to provision the server or network storage. You can get the computing power you need when you need.
Several platforms: provided you have an Internet connection, you can access the service from a laptop, a tablet, a smartphone or a desktop computer.
Resources Group: multiuser model is followed, meaning that there are multiple users of the software.
Quick elasticity. The user receives an experience that increases or decreases according to demand and actual usage. Imagine a hotel that could change one single bed for one of two places in the same “room”.
measured service. The use of resources is monitored, controlled and reported early. This makes the computing power and capacity are basically the same as paying for public service.
From private to public: what cloud is right for you?
In the computer world, a cloud is a large network of cables and server software and services they provide. Like clouds can be formed in different ways, from small to giant storms nimbus, there are several ways that Cloud Computing can take shape. Let us examine in more detail some of the different options based on the cloud.
Public clouds: it is a standardized service that can allow hundreds of thousands of companies use simultaneously but independently. The cloud provider manages the creation of maintenance, security, flexibility and scalability of users for all users of that cloud. These clouds can adapt to companies or academic or government organizations.
community clouds: Community clouds develop when a specific sector has certain needs and requirements in its security arrangements or types of applications, and different companies or organizations join cloud-based problem solving shared resources. A good example is the sector of health care, where insurance providers face similar requirements to hospitals to protect and exchange information and confidential patient records. A community cloud established in this space could meet the specific needs of both parties shared for handling patient records more easily than a general cloud solution.
Private clouds: private clouds consist of a single organization with its own cloud servers and software to use with no public access point. Generally, companies that use private clouds are managed on their own. Sometimes very large organizations with many locations and business units receive assistance from third parties to manage a private cloud. Note that the challenges of capacity planning, procurement of equipment, software updates and security management remain entirely by the owner of the so-called “hybrid cloud”, which essentially is a center of based data virtualization installations.
Hybrid clouds: This type of cloud is a bit more niche and specialized. According to “A View of Cloud Computing”, this cloud infrastructure is made up of two or more infrastructure different (private, community, or public) cloud that remain unique entities but are bound together by itself or standardized technology that enables application portability and data (for example, the outbreak in the cloud for load balancing between clouds).
Providers of these clouds can configure them and give them different ways to meet the specific needs of each company.
SaaS model software as a service (SaaS) Cloud Computing focuses on making software application available to the user via a browser interface or a program. With this model, all the underlying network, operating system and capabilities work behind racks. This is a very popular application of Cloud Computing: it is estimated that 59% of all workloads will be cloud software as a service (SaaS) for 2018, an increase of 41% in 2013.
PaaS: the model platform as a service (PaaS) can reap the benefits of Cloud Computing infrastructure and at the same time maintain the freedom to develop custom software applications. Users can access the PaaS in the same way as a SaaS application. The supplier keeps the operating system, network, servers and security. There may also be abstractions in the application layer to accelerate application development and implementation of various devices. With these abstractions absent-level applications, a traditional platform that runs on a group of virtual servers with remote location will produce certain benefits elastic capacity, but can not be expected to accelerate business innovation.
IaaS: Infrastructure as a Service (IaaS) goes a little further into abstraction, as it provides organizations with the ability to leverage the capabilities of cremes server while the rest of the management of the platform and the software rests with the company . This may allow additional capabilities without worrying about hardware requirements.
The transformative power of cloud technology
All these capabilities have opened the door to the possibilities of software solutions and applications to many sectors. By removing the barrier of the need for technicians to configure and maintain the knowledge infrastructure, companies can afford to have a customizable, reliable and safe alternative. Since most providers PaaS and SaaS are also consumers of other cloud services, each company opens new opportunities that can change the market for companies and their employees.
