In the last post, we reviewed the differences in IaaS, SaaS, and PaaS.
Today let’s explore the IaaS model in more detail. What is it? What are the IaaS types? Why is it important? Find out in the blog post below!
What Is Infrastructure as a Service?
As we already know, IaaS is a service that provides virtual (or non-virtual) computer resources (infrastructure), such as storage, networking, and others via an Internet connection.
How does it work?
IaaS providers host and manage all the physical infrastructure - hardware, storage, and connectivity - in multiple data centers. They also provide other services, such as data backup and recovery, monitoring, and security.
Businesses can access and operate their virtual data centers and computing resources via an Internet connection.
Resources are typically offered via the efficient and cost-effective multi-tenant model, such as VPS. For clients demanding completely separate conditions, providers also offer a single-tenant model, like Bare Metal servers, though this option typically comes with a higher cost.
Why do IaaS matter?
IaaS allows businesses to scale their computing capacity while lowering IT costs. Traditionally, enterprises invested in and maintained their hardware in on-premises data centers, often requiring significant upfront investment to manage periodical high workloads. For example, an e-commerce company may experience three times the usual application traffic during the holiday season, necessitating the purchase of extra servers that remain unused for the rest of the year.
IaaS vendors address this matter by operating highly secure data centers filled with extensive hardware resources. They offer access to this cloud computing infrastructure on a pay-as-you-go or prepaid basis, giving you flexible and safe access to nearly unlimited resources to meet your business, legal, and compliance necessities.
What are the benefits of Infrastructure as a Service?
Speed
IaaS and end customers can access powerful virtual processors, unlimited memory, and storage.
Performance
Most IaaS providers have different data center locations throughout the world. This prevents network latency delays. AlphaVPS offers services out of seven strategic locations.
Scalability
This gives the customer the flexibility to scale resources nearly instantly. If the business outgrows its allocated resources or needs to meet the demands of the busy season, additional server power can be provisioned without delay. The same goes for resources to be scaled back if needed.
Backup and recovery
IaaS providers offer limitless infrastructure for backup and disaster recovery. For instance, you can replicate your applications across multiple servers, ensuring that if one fails, another can take over. Additionally, you can automate and frequently sync data backups to maintain redundancy and guarantee business continuity.
Cost-efficiency
IaaS gives you the opportunity to save money, using a physical or private server, hosted and managed by another company, such as AlphaVPS. This way you do not have to buy and manage physical servers and datacenter infrastructure!
What are the types of infrastructure used as service resources?
There are 3 main types of Infrastructure:
Compute
This includes resources like CPUs, GPUs, and internal memory (RAM)
Networking
IaaS delivers networking components, such as routers, switches, and load balancers. These are usually fully managed by the provider and the end customer does not have to worry about their maintenance.
Storage
Vendors provide 4 types of data storage units:
Local Storage
The storage is directly attached to the virtual or bare metal server.
Block Storage
Block Storage stores data in blocks.
File Storage
Stores data in files, like NAS. Block and File Storage are not as scalable as object storage and may harm the network performance.
Object Storage
Saves data as objects like photos. It is faster, more scalable, better for data analysis, and more cost-effective.
