What is the cloud?
We would not mistake in saying that the cloud is a transformed form of traditional IT infrastructure. In fact, when we started using email services on the Internet, we were considered to have switched to Cloud technology.
It is no secret how companies that do not transform collapse today. Keeping up with the time to be in the forefront it is necessary to keep in mind all possible technological innovations for the development of your business and direct the strategy in this way.
CaspiNet company is the official partner of the following Cloud Providers.
Cloud Technologies are available in 3 main forms (IaaS, PaaS, SaaS). Some sources indicate that it is 4 or more. The components of these models can be seen in more detail in the figure below.
As can be observed from the components of the cloud models mentioned above, IaaS is mainly for projects designed for more specific needs, PaaS is basically for developers and businesses who want to organize services over the cloud without thinking about infrastructure, SaaS is for those who only want to use the services at no IT cost. Thus, the first model is IaaS.
In the IaaS (Infrastructure as a Service) cloud model the cloud provider maintains the entire infrastructure in its data center. This infrastructure includes servers, storage, networking hardware and the virtualization hypervisor layer.
IaaS customers accessing the cloud provider’s portal through a network can create a virtual server or servers in the cloud infrastructure with the necessary parameters, cluster them, create subnets and set rules for data exchange between them, can connect to these servers with applications such as RDP, SSH or console by installing the required OS on the virtual servers they create through a hypervisor hosted the provider.
In this cloud model, you can use any application to download or broadcast over the Internet, as you get administrator or root access to the server.
The IaaS provider also offers other infrastructure components to customers. For example, Billing-Automated Payment System; Monitoring; Log access – event and transaction history, Load balancing, Clustering, or use of several resources as a single resource, and Storage resiliency, such as backup, replication, and recovery.
PaaS (Platform as a Service) – this is a higher model than the IaaS model. If you are a programmer and do not want to be responsible for the components that form the platform of the systems on the server, such as OS – Operating System, DB – Database (MySQL, MsSQL, PostgreSQL), this model is for you. In this case, you will only be responsible for the software you build on this platform.
The main advantage is that it gives you freedom to concentrate on dealing with infrastructure, network, OS, updates, patches, and bugs. At the same time, you do not need to pay a large amount for the OS, Backup, Antivirus, Database license.
SaaS (Software as a Service) – in this model, the customer has the right to use only the software provided by the cloud provider. WebMicrosoft Office365 or Google G Suite products are examples. This model is mainly suitable for start-up business owners or for businesses that do not have dedicated employees who can be responsible for infrastructure, platform, software. The main drawback is that it impossible to intervene or change the system at the level of infrastructure, platform, or software, even if it is necessary. You are a customer who uses the service only under the contract. In conclusion, it should be noted that the use of cloud models is the technology of today and tomorrow. It is the choice of companies with 3-5 or more long-term strategies in terms of economic efficiency. As cloud allows you to save up to 70% on your IT costs. Today, large holdings and companies are migrating to the cloud completely or partially abandoning their internal data centers. In this case, it only remains for you to select the model type.
