Cloud computing is an emerging technology that is becoming a option for business to move from traditional physical storage to cloud storage. Many big name companies, such as Google, Amazon, Microsoft, have started the transition to move some of their data storage and use cloud technology.”80 percent of the large companies in North America that it’s surveyed are either looking at using cloud services—or already have. The market is on its way to generating $100 billion a year.” (Griffith) . This gives an idea of how popular the idea is and how the market for it is growing.
So, what is cloud technology? Cloud technology is simply storing and accessing data and programs over the Internet instead of hard drives. “Cloud” is not actually a cloud but the Internet itself. Surprisingly, we have already interacted with cloud technology already whenever we upload a photo to a photo hosting site, such as Flickr or Photobucket.
Cloud computing in business has become an appealing since it prevents companies from needing to buy extra space and more physical memory for their companies. Companies such as Google and Amazon offer cloud storage and services for smaller business to rent. When a business decided to transition to cloud computing, they have many customizable options that can best fit their business requirements. There are four deployment models available to chose from.
Personal which is mobile cloud storage for storing individual data that can be accessed through Internet connection.This option also has data syncing, which sync all the user data across multiple devices.
Public is in which the enterprise and storage service provider are separate and the data is stored outside of the enterprise’s data center. This can also be access through the Internet and unlock through credentials.
Private where the enterprise and cloud storage provider are integrated in the enterprise’s data center. Access is only available though the business network and is more secure than both public and private.
Hybrid is a combination of both public and private. This allows general data to be accessed off-site while sensitive data to be access like if it was in a private model.
Business can also choose the type of level of cloud computing integration that best suites them. There are three levels of service model options. The first and simplest model is Software-as-a-Service (SaaS). These tend to be more on a pay-per-use basis than renting. This allows users to use applications via the web without the need of installing them.
Platform-as-a-Service (PaaS) is a more complex level of cloud computing.A business can create its own custom applications for use by all in the company in which a outsourcing company provides the operating system,web server, databases, and development tools.This eliminates the need for buy and managing hardware.
Infrastructure-as-a-Service (IaaS) is the final option in service model in cloud computing.An organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. This allows users to have a virtual desktop,email,CRM or communication by using the internet rather than actually having these application physically installed in all the computers. It can also allow for virtual machines which can run multiple OS in a machine that doesn’t have them without the need of installing them physically. The biggest providers of IaaS are Google, Amazon and Rackspace. Netflix uses Iaas from Amazon which store their movie database.
There both positive and negative points for cloud computing right now since it is an emerging technology. Some benefits include file accessibility, off-site back up, and reduced cost since there is no need to install physical application or need to buy more databases to store data.One of the issues about cloud computing is that a company is restricted by it’s bandwidth connection. If a company has slow connectivity, then cloud computing won’t be as efficient.Since it is an emerging technology there are some
security issues that have been noted.
Since cloud computing is on the rise, it should open doors to a new way of approaching how databases are stored and used. It allows business the flexibility to chose what they want and remove any extra costs from the need to buy more memory space and removes from the need of installing applications on computers.
