Amazon, Google, and Microsoft have recently
announced or released new cloud-computing offerings under Infrastructure as a
Service (IaaS).
It has led many to ask: What exactly does IaaS
mean, and how does it fit into the overall concept of cloud computing?
This post will explain all you need to know about
IaaS and why it’s likely to become one of the most widely adopted types of
cloud computing shortly.
What Is IaaS?
 |
| IaaS (Infrastructure as a Service) |
IaaS, which stands for Infrastructure as a Service,
is an emerging IT services model that offers on-demand access to computing
resources via hardware virtualization.
In Infrastructure as a Service, companies rent
their hardware and software needs from providers who provide and maintain these
resources.
When you outsource your Infrastructure needs to a
cloud provider, you can focus more time and energy on developing new products
or improving existing ones.
From Google Docs to Facebook, many services you use
daily rely on cloud infrastructure to operate.
Studies show that 93% of businesses that outsource
their IT infrastructure to an IaaS provider are satisfied with their choice.
Benefits of IaaS
Infrastructure as a Service (IaaS) benefits include
flexibility, scalability, and on-demand capacity.
IaaS is ideal for business continuity and disaster
recovery solutions since it can be instantiated quickly in response to changing
demand patterns.
Another significant benefit is cost reduction. By
consolidating data centers into one location, customers can cut down on their
energy use with elasticity—the ability to scale IT resources up or down
depending on need and resource consumption.
Lastly, Infrastructure as a Service, offers improved
security through multi-tenancy and isolation.
Isolation prevents
unauthorized access by keeping applications separate within virtualized
environments; even if one application is compromised, others remain safe.
Multi-tenancy reduces risk by
providing an extra separation layer between applications and users.
Security with IaaS
(Infrastructure as a Service)
Security has been a massive concern with cloud
services, and rightfully so.
With Infrastructure as a Service, resources stored
in the cloud and available on-demand, they become more vulnerable to attacks.
Even if your provider has top-notch security
measures in place, you cannot know whether or not your IaaS is secure unless
you’re an IT professional with experience securing systems and networks.
For example, when it comes to data storage, one of
the biggest concerns with storing data in IaaS is who owns that data—you or
your provider? In other words, who is responsible for protecting that data?
For example, if you use IaaS for e-mail hosting,
are you protected from spam? Are there viruses being sent through your account?
What about DDoS attacks (distributed denial-of-service) to bring down your
server?
What Makes an IaaS
Provider Different?
When deciding whether IaaS is suitable for your
company, your considerations should be providers’ histories.
Not all cloud hosting services are created
equal/similar.
Many are still developing their Infrastructure as a
service platform, including Amazon Web Services (AWS), Google, and Rackspace.
On top of that, these companies’ public clouds
weren’t developed from scratch.
They were built on other infrastructures with
inherent weaknesses you need to know before choosing an IaaS provider.
AWS, for example, was built on top of EC2 (Elastic
Compute Cloud) servers that had been used by AWS customers previously.
It means AWS has inherited some of its customers’
vulnerabilities—and it can take time to fix them.
What’s next for
Infrastructure as a Service?
Advances in containerization and hyper-scale
deployment will mean that IaaS providers must operate and manage more
Infrastructure at a larger scale.
This is where hyper-convergence comes into play.
Hyperconverged solutions provide enterprises with a powerful alternative to the
traditional server, storage, and networking stacks.
Combining compute nodes, shared storage,
virtualization software, and management tools into one integrated solution has
many advantages over traditional hardware-centric models for virtualization.
For example, hyper-converged systems are easier to
deploy and maintain than traditional setups.
They also offer more scalability and flexibility
than other cloud services because they allow customers to add resources as
needed without changing their existing environment or operating system.
For example, if an organization needs additional
processing power, it can simply add another node rather than purchase entirely
new servers—saving time and money while maintaining consistent performance
levels.
Overall, should we
use Infrastructure as a Service?
IaaS is also a good alternative for businesses who
do not want to sign long-term contracts, or be stuck with costly hardware
purchases.
These include compute-intensive projects like
Hadoop jobs, data analysis, backup, and development and testing environments.
IaaS is also a good alternative for businesses who
do not want to sign long-term contracts, or be stuck with costly hardware
purchases.
And because Infrastructure as a Service is
highly automated, you can typically save money on labour costs compared with
other cloud services.
Conclusion:
In conclusion, IaaS is a crucial aspect of the future of cloud computing. With its ability to provide scalable, flexible, and cost-effective infrastructure solutions, IaaS has the potential to revolutionize the way businesses operate and manage their data and applications.
As technology continues to advance, IaaS is likely to become even more integrated into the fabric of modern business, offering organizations new ways to compete, grow, and thrive in a rapidly changing digital landscape.
With the continued growth of cloud computing, it’s clear that IaaS will play a critical role in shaping the future of technology for years to come.
