Characteristics
IaaS platforms have several characteristics that set them apart from both other cloud services and traditional infrastructure. In general, it's all about offering greater flexibility and affordability than owning your own infrastructure.
Just the infrastructure: When you use an IaaS, you're renting a portion of a server from your IaaS provider. Unless you pay for a dedicated server or a rack, this means you're sharing the same server with other users and companies who are paying for the same service. While this may sound a bit overwhelming, it's an extremely efficient way to share and allocate server resources. Instead of renting an entire server to a single user, a single server's resources can be dynamically allocated to multiple users based on their needs. In other words, no part of the server is underutilized, allowing IaaS providers to charge less.
This model is what allows IaaS to be affordable, flexible, and azerbaijan whatsapp number data scalable. Because resources are allocated virtually, getting more (or less) server space or memory is just a request away. That means you can scale your resources up and down as your needs and requirements change. Compare that flexibility to an in-house server, which will have the same costs and limitations regardless of how much or how little it is used.
Accessible online by multiple users: While each IaaS provider has a single dashboard or interface, they all provide their services over the Internet. While this feature applies to all cloud services, it is especially important to keep in mind when planning stacks or workflows based on an IaaS platform. Since using an IaaS means you'll be accessing key infrastructure through dashboards or APIs, you may need to plan around it. Fortunately, this is mostly a big advantage. By distributing the same service across multiple interfaces, IaaS providers ensure that all users have full access (and full control) to their computing infrastructure.
Pay-as-you-go pricing: As an extension of offering a flexible service, most IaaS providers also offer flexible pricing. Typically, most IaaS providers charge by hours of usage. This metric is broken down into two main components: (i) resources consumed and (ii) hours used. As you can imagine, these two variables are flexible, with most providers charging modest fees for both long hours of low resource consumption and short hours of high resource consumption. In this case, resource consumption could be RAM (memory) used per hour, storage in gigabytes (GB), etc.
