Cloud hosters ensure that there is enough server capacity – but not too much. This saves unnecessary hosting costs. But the cloud hosting market is big – we give an overview.
Whether shared hosting, virtual or dedicated server: conventional web hosting is a predictable thing. At least as far as costs are concerned: the customer chooses a service package that meets their requirements – and pays a fixed price for it. Often, however, it is very difficult to properly assess the requirements. How much webspace you actually need, what the hosting package has to do and what service is necessary – this exact requirement profile usually only arises in daily practice. And it’s changing constantly. So classic web hosting is pretty unpredictable.
For this reason, cautious agencies rent oversized hosting packages for their customers – and usually pay far too much. Price-conscious agencies start with little hosting service, but often have to improve. Successful agencies, however, rely on cloud hosting: “At any time scalable, virtualized servers always provide the power that is currently needed,” describes, for example, the Domain Factory GmbH Jiffybox offer. You can not really explain cloud hosting better.
What is cloud hosting?
Cloud computing includes three areas. The basis is Infrastructure as a Service (IaaS), ie the provision of virtualized hardware resources via the Internet. This is the basis for the Platform as a Service (PaaS) solutions. These are working environments for developing web applications. Unlike IaaS offerings, PaaS solutions usually do not allow access to the operating system. Finally, the third layer is Software as a Service (SaaS), which means ready-to-use web applications.
Cloud hosting is an Infrastructure as a Service (IaaS) service that provides users with access to virtualized hardware resources over the Internet and can set up appropriate computer clusters for their own purposes. Mostly it’s about hosting special web applications and large amounts of data. This allows cloud hosting offerings to be separated from developer tools such asMicrosoft Azure * or Heroku – even if these boundaries sometimes blur.
What is the difference between private and public clouds?
Basically, a distinction is made between private and public clouds. Private clouds – also known as “dedicated private clouds” – are dedicated server environments in which the user can operate his own private cloud. Only one customer uses the infrastructure here. This increases security but limits the scalability of hosting offerings. For this reason, private clouds are predominantly aimed at companies that prefer a closed hosting environment for security or other reasons.
On the other hand, public clouds are much more in line with the basic idea of cloud computing: the hosting provider has resources available that all customers share. Each customer gets the optimal hosting service for him. Ideally, he can freely choose and change all hardware and software options at any time, ie scale them live: During operation, any server parameter can be changed, such as the number of CPU cores used, memory or hard disk size. In addition, some vendors automatically adjust the resources they use as hardware requirements change – which is called autoscaling. This is real cloud hosting. Often one recognizes that there is not talk of servers, but of instances – but that is not always and everywhere.
Minute price instead of monthly fee: How to settle for cloud hosting
This on-demand scalability is accompanied by billing models that are fundamentally different from traditional hosting offerings. Instead of paying a fixed monthly fee for a server, instances of cloud hosting are typically paid by actual usage or the amount of data used: pay-as-you-use. Depending on the provider, billing takes place from seconds to hours.
If instances are not used, they can “freeze” them at some providers and significantly reduce the price of use. If you expect longer idle times for your projects, you should pay attention to a suitable price option when selecting the cloud hosting provider.
