Quite recently, we talked about IT infrastructure in a blog post. It can include servers, PCs, routers, web servers, operating systems, CMS and even data centres. The IT infrastructure may be owned by a single company. This kind of infrastructure is called traditional infrastructure. The infrastructure can also be rented from another company. This is called leased infrastructure. This article will talk about IT infrastructure as a service, namely IaaS.
The IaaS model – what is it
What opportunities IaaS offers
- A VPS on which you can install any operating system and software. You don’t need to install the OS yourself most of the time because the IaaS provider does it for the client beforehand. You can connect a single server or several.
- Off-the-shelf networking solutions. They allow virtual servers to communicate with external servers and the Internet. VPN (data encryption technology), traffic load balancer, traffic routing, etc., are also installed as part of the network settings.
- User access control. Not all information needs to be available to all employees. You can restrict access to individuals or only allow them to view without the ability to edit.
- Cloud storage for storing files or backups. There can always be problems with the site. They can cause loss of site files or user data. To allow the owner to recover them, it is essential to create backups. These can take up a lot of storage space, but you will always have peace of mind that your data is safe. Unlike cloud drives (like OneDrive or Google Drive), IaaS has a larger storage capacity.
- Backup infrastructure. They ensure the entire infrastructure against possible breakdowns.
Why cloud infrastructure is gaining popularity?
The benefits of IaaS
- Savings on hardware and its maintenance. Why waste time and effort buying hardware, putting it in a purpose-built building and configuring software? Let someone else do all that, and you only pay for the capacity you use.
- The provider’s technicians handle the uptime. The servers need to be kept up to date, and all systems need to work correctly. When you lease out a facility, all the uptime support falls on the shoulders of the service provider.
- Project scalability in a short time frame. If you suddenly realise that you do not have enough dedicated resources, you can quickly rent more from a tenant.
- It’s easy to reduce the amount of leased capacity. When the hardware is yours, it’s not so easy to get rid of it. And if you rent it, all you have to do is give up the resources you don’t need.
High reliability and security. Companies that provide IaaS keep their servers under the strictest control because they are responsible for the data of hundreds of users. They are well aware of what needs to be done to secure the information.
- For start-ups. Start-ups do not yet have the money to build their own infrastructure, and it is not clear whether their business will grow or the project will collapse in the first month. Also, technology that has already been prepared will enable faster business start-ups.
- For projects with a variable workload. For example, this applies to online shops with seasonal products. When it’s time for big sales, you need to increase system resources quickly. On the contrary, when the demand drops, they need to be reduced.
- For software development and testing. Infrastructure-as-a-Service (IaaS) allows developers to quickly deploy virtual machines with the correct operating systems to test a new software product. Extreme environments can be shut down once the development process is complete and unnecessary services can be paid for.
- To support websites and applications. The IaaS model can give you all the infrastructure to support a large website or application (web servers, storage, network resources). You can also scale the help at any time.
- For extensive data analysis (Big Data). The more data sets you need to process, the more computing power IaaS can provide without a significant investment.
- For data backups. No need to spend time and resources on separate cloud storage and management. With an IaaS cloud, you can rent any size storage, which is flexible in copying data and easy to restore.
