Did you know that many people today use cloud technologies for personal or business purposes, even if they are not aware? If you are watching movies and series on Netflix, listening to your music on an app like Spotify, using an email address or any storage service to store your data, such as photos and videos, then you have more or less an idea of what this technology is. Come now, let’s examine the cloud technologies that are so much in our lives in 5 items with their general terms.
1- What Are Cloud Technologies?
Cloud technologies, also known as cloud computing, are essentially a set of services that allow users to access on-demand computing resources that cloud service providers store in their data centers. This innovation was first started in the 1960s when IBM virtualized operating systems and Arpanet, the pioneer of the internet, emerged; and it was first introduced with Amazon S3 in 2006.
This service owes its existence to virtualization technology, which allows physical servers to be divided into multiple virtual servers. Because, it becomes possible to use many applications and operating systems at the same time on the same server by means of this. In this way, thereby the approach to science and technology resources changes greatly; the workload of companies is reducing and efficiency is increasing with the disappearance of works such as software, hardware, infrastructure.
For people, we can say that this eliminates the need to store data on computers, phones or tablets. Thus, we enjoy the convenience of accessing our photos, videos, messages or documents stored in the server storages, from any device connected to the internet at any time.
2- What Are The Features?
Cloud eliminates the dependence on a certain device by collecting data on a remote server; and offers a flexible and scalable service with the larger storage space and more powerful server performance. In other words, depending on the increase in storage space needed, you can easily rent extra space and pay only for what you use.
Before that, companies had to have an IT (Information Technology) department as they had their own in-house servers, hardwares and softwares. In addition, technical operations such as increasing the number of hardware according to the number of employees and updating software were also among the responsibilities of the companies. But with this innovation, hardware and software offering by the provider, reduces the cost significantly. Thanks to this, all you have to do is focus on the core business using the cloud platform supplied by the service provider.
Access to data centers by only internet connection gives many advantages, but can also be seen as a disadvantage. Because access to the server is not possible without internet and the processing speed can also decrease to the quality of the connection. However, although various security measures have been taken, cloud data stores are also considered less secure than the local server.
3- Different Cloud Services According To The Needs
Cloud services offer a variety of convenient options based on free or pay-as-you-go with different models, eliminating the need for the people or companies’ own infrastructure and hardware. We can collect these services, also called the “cloud computing stack” because they are built on top of each other, under 4 headings in general:
Software as a service (SaaS) is the most common model. SaaS addresses end users directly and provides access to the cloud service by a web browser. Here, while all hardware and software operations are managed by the provider, all that remains for us is to use the software. In addition to free personal use on SaaS, different applications are also available for corporate use for a fee. Examples include web-based email services such as Gmail and hotmail, as well as dropbox and Gsuite, which allow data storage.
Infrastructure as a service (IaaS) provides full control over the infrastructure provided to the client through the API. In this way, it becomes possible to control it completely, just as in in-house physical infrastructure. Popular examples of IaaS include Microsoft Azure and Amazon Web Services.
Platform-as-a-service (PaaS) provides a database, programming language, and operating system, creating an ideal environment for users to develop cloud-based software. While PaaS has all the benefits of IaaS, it also includes features such as development tools. Services such as Google App Engine and AWS Elastic Beanstalk offer ease, speed, and low cost in developing and testing software applications.
Serverless computing service manages all infrastructure operations, allowing developers to focus only on business logic. Services such as AWS Lambda provide an advantage to the user by increasing speed and production efficiency.
4- Types Of Cloud Computing
Within the public cloud, all infrastructure, software and hardware are owned and managed by the service provider. Thus, employees or people can access the server by connecting to the internet with any device. The public cloud is open to all users who request it for free or a fee. For example, by logging in Google Drive with a user account, you can instantly start using a certain storage space for free.
Private Cloud is also called internal cloud or enterprise cloud. While carrying the benefits of the public cloud, this is only provided to specific users. Computing resources available on an internal network as well as the internet, are closed to third parties. A private cloud that is more secure by meaning of this, leads to in-house IT spending, as in traditional technology, because its management is user-owned. IBM Bluemix is an example of this type.
Hybrid cloud, as the name suggests, is a combination of public and private cloud. This combination makes it possible to transfer data between the public and private cloud, depending on the suitability of the applications or jobs.
Multi-cloud is another type of service got from several different service providers. As well as public and private clouds, various services such as SaaS and PaaS, are used together. Thus, companies find a chance to combine services for their needs from many providers. It is often preferred by such companies.
5- In What Areas Is It Used?
Both people and companies from different sectors can perform operations such as data storage with cloud technologies. In this way, the data center becoming independent of the device, provides flexibility in access and prevents data loss in case of device corruption.
Call centers find an opportunity to work remotely with the opportunities offered by mobile operators, such as calling with a fixed line over mobile phones, saving voice recordings of conversations, and receiving calls automatically. Cloud services, of which we have begun to take more advantage especially with the pandemic, provided significant convenience to employees.
Day by day speed becomes more important in our lives, particularly in the field of technology. The cloud service, which provides a significant advantage in application development, allows products to be improved and released faster.
Websites can be easily prepared and published in minutes via cloud-based servers such as WordPress and Wix. With user-friendly interfaces, the site can be easily managed without requiring any code knowledge.
Cloud technologies that have been in our lives for more than 10 years are now used by 92% of organizations. While big brands like Google, Microsoft and Amazon continue to offer their own cloud services, finally last month, Turkey’s one of the major e-commerce sites, n11.com also announced that it has launched n11cloud by investing in this area. According to these advances, cloud technologies are expected to develop further in parallel, especially with the spread of 5G technology.
