It is estimated that by 2020, the average person will have 1.5GB of data per day. As more and more devices are connected to the Internet and generate data to the central server node in the cloud you may encounter bandwidth bottlenecks.
Real-time data processing: According to statistics, unmanned vehicles generate approximately 1GB of data per second, data per second Boeing 787 generated more than 5GB; 2020 China's data storage capacity of about 39ZB, of which about 30% of the data from the Internet of Things access device. Real-time processing of massive data may make cloud computing powerless.
Privacy and energy: the body wearable computing cloud, privacy collected data transmission equipment medical, industrial manufacturing and other paths to the data center is relatively long, easily lead to loss of data or information leaks and other risks; high load of the data center due to high energy consumption the core problem is the data center management planning.
In this article we will cover all the information, such as history, characteristics, strengths, weaknesses and cloud types. In addition, we will understand the cloud computing deployment model, and a list of companies that use it. So, you ready to learn more about cloud computing?
What is cloud computing?
Cloud computing is a service to provide customers with Internet services. It simply means that cloud computing means by a hard disk to store and access data and programs the Internet rather than a computer. Data can be anything, such as music, files, images, documents, and so on.
Users only need to use the Internet connection to access data from anywhere. To access the cloud computing, users should be registered for safety reasons and to provide an ID and password. Transmission speed depends on various factors, such as the Internet speed, capacity, etc. server.
Cloud management is done by the host themselves because they proposed a new modification to continuously improve service. Host with sufficient memory and fast processing server, the data can be accessed very quickly through them. The main advantages of cloud computing is that the user can focus on the work, while the problems behind.
Cloud computing history
Before the emergence of cloud computing, there is a client / server computing, centralized storage, where all data, software applications and controls reside on the server side.
If you want to run programs or access to specific data, then he will connect to the server and get the proper access rights and can conduct business. After the emergence of the concept of distributed computing, in which all the computers are networked together and share resources when needed.
Cloud computing concept appeared in 1950, can be accessed thin / static client and implement large-scale computer through. Then in 1961, John McCarthy delivered a speech at the Massachusetts Institute of Technology, he suggested that the computer can be sold like electricity and food the same. The idea is great, but it far exceeded its time, although interested in the model, but the technology was not yet ready.
In 1999, Salesforce.com has become the first company to enter the cloud areas of the company, specializes in the concept of enterprise-class applications to end users via the Internet. Then in 2002, Amazon Web Services Amazon is proposed to provide computing, storage and even human intelligence and other services. In 2009, Google Apps and Microsoft's Windows Azure cloud computing also started offering enterprise applications. HP and Oracle and other companies have joined the flow of cloud computing to meet the needs of larger data storage.
In this part of the cloud computing tutorial, we will explore three types of cloud computing:
SaaS
SaaS software as a service representatives, to provide users with the convenience of using software from anywhere with the help of an Internet connection. It is also known as on-demand software. Since the service providers, host applications and their associated data in its position, it can be accessed remotely. There are various benefits of SaaS, because it is economical, only users have to pay basic expenses such as license fees, installation fees, maintenance fees and support costs. Some examples of SaaS are Yahoo! Mail, Hotmail and Gmail.
Close
PaaS Platform as a Service representatives. This is made in a managed environment by providing, publishing and custom software tools to help users. Internet connectivity help to achieve this goal. It also has several benefits, such as it has a lower cost, users must pay only the basic things. PaaS hosts have their own hardware and software. This eliminates the need to install new hardware and software to perform application.
Cloud Computing Curricula - PaaS (Platform as a Service)
IaaS
IaaS Infrastructure as a Service representatives. With the help of the IAAS, users only pay the basic price to use IT hardware and software. The company is using IaaS IBM, Google and Amazon. With visualization, the host can create and manage infrastructure resources in the cloud. For small businesses and start-up companies, IaaS has a major advantage because it makes the infrastructure to benefit, rather than spending a lot of money on hardware and infrastructure. The reason for choosing IaaS is that it is easier, faster and more cost-effective, thus reducing the burden on the organization.
Advantages of cloud computing
economic
Cloud computing is the economy, because there are many free users the opportunity to use it at the beginning, then, they only need to pay for basic services. For the general public, there are many reliable service can be used for no-cost or low cost.
24-7 Availability
Each can use cloud services because all queries and provide technical support issues are resolved by a phone call. Workers can get help from anywhere.
Safety
Since the data is stored in multiple locations, you will not lose data. Cloud computing provides a high level of security, because data storage is very important and should not be lost. Data can be modified or deleted from anywhere via remote access. Even if the device is lost, it can make use of an Internet connection to modify or delete data from anywhere.
Disadvantages of cloud computing
Shutdown
One of the major disadvantages of cloud computing is downtime. If the company's servers are not accurate, which will result in downtime, because it will not perform properly and data access tools can reject it.
Vulnerable
If you connect to the Internet, you may experience severe attacks, because you may encounter potential vulnerabilities. Fewer opportunities, but sometimes even the best teams will also be affected.
Cloud deployment method
A method for the deployment requirements vary according to four kinds of the cloud. Customers can choose the most suitable for their products. Let us take a closer look at all deployment methods:
Private Cloud
Public Cloud
Community Cloud
Hybrid Cloud
Private Cloud
This is a particular cloud company, responsible for the maintenance of cloud management, deployment and operation. This operation can be carried out inside or with a third party.
Community cloud
These companies have similar interests and work. They can share the same cloud, it can be done with the help of the community cloud. Save settings when creating the initial investment.
Public cloud
In a public cloud, the company on a commercial basis to provide customers with infrastructure. This helps customers develop with minimal financial outlay and deploy applications.
Hybrid Cloud
Mixing the cloud, the application can easily be moved to another cloud from a cloud. Hybrid cloud is a combination of public and private clouds, and the ability to handle data in support of the organization.
in conclusion
Cloud computing is a major focus, because the company is generating large amounts of data for future analysis. The company is introducing a faster server to provide services quickly and provide fast access. With cloud computing, users can focus on different aspects of the company and help it develop.
