The emergence of cloud services
Cloud services appeared in the early 2000s. Their emergence became possible only due to the development of Internet speed, growth of computing power and the leap in network equipment capabilities around the world. Russia did not lag behind - the first cloud services appeared in our country around the same time.
One of the pioneers of cloud computing abroad is Amazon Web Services (AWS), it was launched back in 2006.
The idea behind cloud services is simple: providing access to computing resources (such as disk and other storage devices, data processing tools, or even specific software). In the case of the cloud, this access is provided via the Internet wordpress web design agency instead of using local resources. This approach allows you to access data and applications from any device connected to the Internet. You only pay for the resources that will actually be used.
Types of Cloud Services: IaaS, PaaS and SaaS
There are three main categories of cloud computing models: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). In principle, the meaning of each of these models can be easily grasped in these brief explanations. But let's expand on them in a little more detail.
IaaS - refers to the underlying computing resources (servers, storage, and networks) that customers can use to deploy their own applications and systems.
PaaS – takes it one step further by providing a complete platform. Typically, it is a platform for building applications using ready-made tools and programming languages.
SaaS is a comprehensive software solution. You don't need to download anything, because access is usually provided through a browser or web application. There is no need to run them locally.
What types of clouds exist
Clouds can be classified primarily by access type. Here is the main difference between these types:
Public cloud - allows you to access services via the open Internet and run them in a shared or virtualized provider infrastructure.
Private Cloud - Located behind an organization's firewall, they offer dedicated hardware, storage, and networking capabilities for a single company.
Hybrid cloud - combines the capabilities of public and private models.
How to switch to cloud services
This is a global process. It requires financial, human and time resources.
The transition to the cloud requires planning. It is better if it is handled by specialized specialists. If there are none, experienced MSPs and cloud service providers themselves will help out.
Preparation
The first step is to assess your existing infrastructure and workloads. It is important to decide what can work as is and what needs to be optimized.
Moving
OS preparation, data migration itself, security integration are in progress. During migration, reduction management is performed (for smooth transition of services without downtime). After migration, further tests are set up. Different types of tests ensure that everything will work without failures.
