The modern cloud services market may seem to an outsider like a separate state with its own laws, rules, and even its own language. To avoid confusion in terminology and to make an informed choice in favor of one of the most common cloud models, we have prepared a short guide in which we will literally analyze the meaning of the abbreviations IaaS, SaaS, and PaaS brick by brick. We will not confuse the reader with complex technical analogies and will turn to an example from the world of pleasant and understandable things - the Lego constructor
IaaS - Cloud Infrastructure as a Service
You go to a Lego store and rent boxes of assorted parts. You use some, you don't. You can build anything from a Millennium Falcon to a Ferrari, depending on your experience and the time you're willing to spend on assembly.
In other words, under the Infrastructure as a Service model , the cloud provider provides wordpress web design agency you with all the necessary infrastructure and virtual resources, while the physical servers are located in a secure data center and serviced by a team of professional engineers. Most often, under this model, cloud providers provide public cloud resources.
The key task set before this cloud model is to give the business the opportunity to use IT resources of the required performance without the need to purchase, configure and maintain equipment. The provider also takes on modernization, so you do not have to worry about updating the IT park yourself. However, all operations related to the corporate service hosted on the server (installation of the OS, software, placement of applications and their management) are taken on by specialists from the customer's side.
Benefits of IaaS
The advantages of the model include:
no capital expenditure on equipment purchase;
savings on its administration;
reduction of costs for the relevant staff of specialists;
rapid deployment;
flexible scaling options - you can add resources at any time by agreement with the provider, and turn them off when you no longer need them.
convenient payment models: for example, PAYG (Pay as you go) involves hourly billing and payment only for the capacity actually used.
Who is IaaS suitable for?
For a variety of reasons, businesses are abandoning local infrastructure and switching to cloud services. Therefore, infrastructure as a service is relevant for both microenterprises and startups, which often do not have their own IT resources, and for large players. Infrastructure as a service saves the IT budget, reduces the time it takes to implement new business applications and systems, and helps businesses increase flexibility and respond more quickly to changes.
