Cloud Computing

By definition, cloud computing is indeed a revolution. Cloud computing is making a fundamental change in computer architecture, software development and tools, and of course in the way we store, distribute, and use information. Cloud computing combine private cloud, public cloud, hybrid cloud and community cloud. Let’s find out with us in this article.

What is cloud computing?

Cloud Computing, also known as Virtual Server Computing, is a computer model that utilizes computer technology and is based on the Internet. The term “cloud” is metaphorical for the Internet (based on how it is arranged in the computer network diagram) and as a connotation of the complexity of the infrastructure contained within it.

Over the past few years, cloud computing has revolutionized the computing industry, fundamentally changing the way resources are used, the operating structure as well as the storage, distribution and information processing. Most of us have been using one or more cloud computing services in everyday life as well as in enterprise management.

In this computing model, all possibilities related to information technology are provided in the form of “services”, which allow users to access technology services from a certain provider “in cloud “without the knowledge and experience of that technology, nor should it consider the infrastructure that serves that technology.

Why cloud computing has become a trend?

  • The biggest benefit of cloud computing is the cost savings. We’ve been analyzing this aspect for quite some time now, so maybe not much. Mainly you will reduce the cost of initial infrastructure investment, the cost of purchasing hardware, software and maintenance, the cost of installation, server placement and daily operation, the cost of hiring people to custody and much more.
  • Followed by the convenience. You can quickly use something without complicated installation. You can quickly access them anytime, anywhere, almost without being dependent on what software or hardware you are using. If you are using a traditional storage drive but forget to stay home, how can you get the data? While using Dropbox, just go to its web site and download the necessary file is the end of the story. Or like Gmail, you can quickly borrow your laptop to check mail without having to set up a messy account in Outlook, even without Outlook. Or Google Docs too, just open the browser and type, no need to install more office cloud computing models.

Cloud Computing has 3 main service models (product models):

  • Public Cloud: Cloud-based services are for individuals and organizations that share resources.
  • Private Cloud (used in a business and not shared with users outside of that business)
  • Hybrid Cloud: A hybrid model between Public Cloud and Private Cloud models.

Different models of cloud computing.

Public Cloud

These are the services provided by the 3rd party (seller). They exist outside the corporate firewall and are managed by the cloud provider. It is built for public use, users will register with the provider and pay a usage fee based on the price policy of the provider. Public cloud is the most widely used deployment model of cloud computing today.

Target customer: Includes users outside the internet. Managed object is the service provider.

Advantages:

  • Serves more users, not limited by space and time.
  • Saves server system, power and labor for business.

Defect:

  • Businesses that depend on suppliers do not have full control.
  • Difficulties in storing documents, internal information.

However, the public cloud has a drawback, which is the loss of control over data and data security. In this model, all data is on the cloud service, protected and managed by the cloud service provider. This makes customers, especially large companies, feel insecure about their important data when using cloud services.

Private cloud

Private cloud provides a dedicated infrastructure (which can be integrated on existing systems, or stored in a data center of a cloud computing service provider) for a single certain businesses. This feature helps businesses take advantage of cloud computing – such as superior adaptability, speed and efficiency – and can be tightly controlled and enhanced with much greater security with public cloud. Therefore, private cloud services often have higher costs.

Benefits of private cloud.

Private cloud computing is often considered to be the most ideal platform for deploying business-critical applications, or for businesses requiring high levels of customization – which is difficult to achieve in a public cloud computing environment. In addition, private cloud computing also helps minimize latency, as the service is accessed over an internal network rather than through the normal Internet.

With these characteristics, private cloud computing is often suitable for complex applications or businesses, or for strict data compliance and compliance.

In fact, many businesses are anxious to choose the right cloud model. Once the decision has been made, businesses are forced to use that model in all future operations because of the very different public cloud and private cloud setting. There are no solutions to smooth workload switching between these two cloud models. Every transition between the current system and cloud computing requires a variety of source codes, security profiles, network configurations, test environments, and automated tools.

Hybrid cloud

Now, when it intends to transition to cloud computing, businesses will not need to make a “no return” decision, because hybrid cloud computing will help businesses leverage the superiority of both models, while providing a perfectly reasonable choice for every business. Hybrid cloud computing will provide a completely integrated infrastructure, policy, and security tool that will help businesses choose whether to deploy on existing fixed or computing platforms cloud.

One of the main advantages of hybrid clouds is the ability to move applications and workloads between environments, depending on requirements, business needs, and other factors. This combined approach enables businesses to instantly respond to operational processes – such as using public cloud computing to rapidly develop and test new applications, before switching back and setting fire mode in operation. This feature also helps most enterprise applications take full advantage of cloud-based deployments – though initially only integrated in the private cloud platform.

This innovative solution can only be achieved through a groundbreaking cloud computing technology – fixed public cloud computing – using the same software and hardware as the dashboard computing platform. The public cloud aims to integrate all of the functionality right on the existing fixed-line system, enabling businesses to harness the power of the public cloud computing platform while maintaining the same level of control they need data center.

Basically, with this technology, businesses can define specific business requirements and regulations, as well as the need for data management and positioning capabilities, while still benefiting all. Utility of public cloud: very flexible and charge rate depending on the traffic used.

By eliminating the gap between two different cloud computing models, businesses can leverage the flexibility of cloud computing, take the lead ahead of their competitors, and be ready to respond. The demand is constantly changing and the competition environment is increasingly fierce.
