We are moving towards a technologic world where the cloud is part of our daily lives in terms of connectivity and communication. For this very reason, the idea of IaaS has been born, where a modern infrastructure for storage, advanced servers and networks is provided.

What we mean by Infrastructure as a Service is a business model where cloud providers host space on their servers to store computing, network or other resources. Companies and individual users rent the infrastructure for applications and operating systems on demand.  

If an organization would like to scale to Iaas, it is offered a viable alternative to a scale-out to leave traditional in-house infrastructure. This can help companies lighten on-prem resource demands and be more efficient over the workload, while also avoiding maintenance and operational costs for server management.   

Iaas is created by physical and digital resources that allow users to run applications and jobs in the cloud. It offers various solutions such as messaging, databases, content distribution over the network and serverless functions. All this works under 4 main blocks: hardware, network, storage and computing.  

  • Hardware: Providers run large global data centers which house physical machines to power the digital infrastructure. End users do not usually interact with these centers, but they are essential to keep servers running and data accessible.   

  • Network: Networks enable the connection between systems and users, so that they can access, share and change data and resources. APIs and SDNs play the role of traditional network devices such as routers, switches and firewalls.
  • Storage: One of three types of storage is offered in the cloud
    • Block storage: Data is divided into blocks and stored as separate pieces, so each has a unique identifier. 

    • File storage: Data is stored in files, which are also divided into folders and live under the directory hierarchy.   

    • Object storage: Data units are stored as self-contained repositories that include metadata and unique identifiers.  

  • Computing: Includes the basic technologies needed to run processes, handle workloads, and store and store data. Service providers can offer both CPUs (central processing units) and GPUs (graphics processing units) for different types of workloads.  Cloud computing contributes to high performance and scalability when combined with supporting services such as auto scaling and load balancing.

What are the main uses of IaaS?  

Testing and development: Facilitates the creation and decommissioning of new environments for testing and development. It enables teams to develop applications easily, so they can bring their applications to market faster and reduce testing costs.  

Storage, backup and recovery: Enterprises minimize internal storage expenses and its management, which requires qualified personnel to manage legal and regulatory compliance. It also allows companies to handle less spikes and drops in demand, thus providing an outlet for growing storage needs and functioning as backup and recovery.  

Web applications and website hosting: Web applications are supported with storage resources, networks, and web and application servers. With this you can deploy web applications and scale up or down your infrastructure on demand.   

High performance computing and data analysis: Supercomputers, computer networks or computer clusters can be incorporated with the processing power needed to analyze large data sets and solve complex problems.  

What are the benefits of Iaas?  

Pay-as-you-go flexibility: IaaS does not require the upfront investment of building and managing a data center. In addition, service providers typically work on a pay-as-you-go model, billing only for what is used: the operating expense (OPEX) model.  

Scalability: IaaS helps you quickly adapt your resource allocation in response to changing business conditions. Rapid deployment of resources makes it easy to manage multiple workloads and peak demand for your applications, and it is just as easy to scale down and save budget when activity slows.  

Rapid innovation: Because IaaS is self-service, users can quickly get the additional bandwidth they need to test new ideas and deploy proven ones at scale. This flexibility provides great support for product launches and other initiatives.  

Resiliency and continuity: System outages and failures are especially disruptive for organizations using legacy systems, so with Iaas there would be a solution as users can access hosted data and applications.   

Operational stability and support: No need to worry about maintenance, upgrades and troubleshooting. It is the service provider’s responsibility to keep everything running reliably and provide support.    

Prioritization: By taking care of your infrastructure needs, IaaS frees your team to focus on new and valuable projects.  

Considering all that has been mentioned so far about IaaS is that it can provide a technological and innovative solution for a digital transformation for companies looking to optimize their infrastructure. Many companies, at the time of having an IaaS service, usually consider applying more than one solution in order to reduce costs, avoid risks and have a solution for their needs. If you have a multicloud environment, you can have better compatibility, agility and excellent service.
