Cloud Infrastructure-As-A-Service

Cloud computing is a powerful technology that gives every individual the same access to strong computing power. With cloud computing, information and software are available wherever and whenever you need them. It makes working from home possible, and playing your favorite games on the go. Cloud-based data and applications are accessible from any internet-connected device. This empowers businesses to develop and roll out new products and updates very quickly, especially combined with cloud infrastructure-as-a-service.

Cloud computing also protects against data loss where failed equipment no longer means the loss of valuable and irrecoverable data. Cloud computing makes accessing incredible power possible for more people and more businesses. It is much cheaper to pay for cloud infrastructure services than to build and upkeep hardware systems yourself. Many cloud infrastructure-as-a-service providers utilize a “pay-as-you-go” structure where you only pay for the resources you use. 

Cloud computing has made it easier than ever to utilize the benefits of powerful hardware and rooms of servers, but it hasn’t gotten rid of the hardware and servers altogether. Cloud computing has simply made it possible to outsource the build, scaling, and upkeep of hardware. In other words, the infrastructure. In order to utilize the cloud at all, organizations must find an infrastructure-as-a-service provider. These service providers allow businesses to focus on other aspects of their work such as customer service and product development without maintaining a costly full-service IT infrastructure in-house. 

Some popular infrastructure-as-a-service examples you may have heard of include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud. Infrastructure-as-a-service is also commonly referred to as “IaaS.” 

There are many advantages of IaaS. IaaS is one of the most flexible cloud computing models and allows for the most control over applications, runtime, operating systems, and data. With IaaS, organizations are still responsible for their own systems and data. The IaaS model makes it easy to deploy additional resources as needed and scale back when they are not necessary. This also helps to recoup costs, as resources are only paid for as they are used. Infrastructure as a service in cloud computing is highly scalable. It is an ideal choice for startups and small companies who do not have the time or expertise to create and manage their own hardware. IaaS is also a popular choice for large companies that wish to outsource their hardware while maintaining total control over their infrastructure. 

IaaS examples like Microsoft Azure make it possible for businesses to scale quickly without concerning themselves with the minute data of their computing hardware. With IaaS, they maintain total control over the things that matter, such as applications, operating systems, and data. IaaS vendors manage virtualization, servers, storage, and networking. IaaS providers like Skytap allow enterprise organizations to migrate and run legacy systems in the cloud with ease.

Cloud Infrastructure Services

Which are some of the key components of cloud infrastructure-as-a-service? Cloud IaaS providers build and deliver networks, servers, storage solutions, and virtualization (access) so that organizations can focus on other aspects of their business.

There are a few different types of cloud computing – public, private, and hybrid. In a public cloud, data and other information delivered over the internet can be shared with people and organizations without special permissions. In a private cloud, only users within your organization can access data and information. A hybrid cloud approach is a combination of features from a public and private cloud. There are four types of cloud computing in all. Multi-cloud is also an option, including all of the additions above. Multi-cloud refers to the usage of more than one cloud vendor in the same type of cloud (public or private). 

Public clouds are typically used to provide web-based services such as email, online office applications like Microsoft Office Online or Google Docs, cloud storage, testing, and development environments. Public clouds tend to be more affordable than other cloud infrastructure architecture, and you only pay for the resources you use. 

With private cloud infrastructure services, cloud computing resources are used exclusively by one business or organization. Private clouds are typically utilized by organizations that require a high level of security such as government agencies, financial institutions, educational centers such as universities, or other large organizations with a strong desire to maintain control over their digital environment.

Hybrid clouds are a form of IaaS in cloud computing that makes use of on-premises infrastructure, private cloud services, and public cloud services. Hybrid cloud infrastructure requires a detailed level of orchestration to create interaction between all platforms involved. Hybrid clouds are a good choice for organizations that require agility or frequently experience wildly varying levels of service and usage.

Iaas, Paas, Saas

There are three types of cloud computing – IaaS, PaaS, SaaS. We’ve covered infrastructure-as-a-service (IaaS) in the sections above, but PaaS and SaaS are other types of cloud computing that both businesses and individuals use every day.  

So what is PaaS, exactly? PaaS stands for Platform-as-a-Service. IaaS and PaaS both provide ways for businesses to scale their operations without managing their own hardware and infrastructure. The platform-as-a-service definition is very basic and not all that different from IaaS – it’s a cloud computing model where a service provider delivers and manages hardware and software tools to users over the internet. However, the two services do offer very different levels of control. In IaaS vs PaaS, organizations maintain and manage their own applications, data, runtime, middleware, and operating systems. In PaaS, organizations only manage their applications and data. A PaaS vendor manages runtime, middleware, operating systems, virtualization, servers, storage, and networking. 

Common PaaS examples include Heroku and Apache Stratos. Other platform-a-as-a service examples are Google App Engine and even Facebook. PaaS providers give organizations the power to develop apps without paying for hardware and other processes. These services enable organizations to build and deploy application products on the platform at a fraction of the cost. 

What is SaaS? SaaS stands for software-as-a-service. SaaS is a software service in the form of a product and is a widely utilized method of cloud computing. SaaS softwares can commonly be used for business functions as well as personal enjoyment. For example, Netflix is one of the most popular SaaS examples. Other examples of SaaS include HubSpot, Dropbox, Slack, Spotify, and more. Like PaaS and IaaS, SaaS is managed from a central location and hosted on a remote server. It is accessible over the internet, and end-users are not responsible for hardware updates. However, when it comes to PaaS vs SaaS, PaaS provides users with more flexibility and control. PaaS and SaaS can not be used interchangeably and have entirely different purposes. SaaS is great for users that don’t require a lot of hardware or processing power in the first place, such as very small businesses or individuals. SaaS is typically also ideal for applications that need to be accessed via web browsers and mobile devices. The advantages of SaaS in cloud computing provide a more hands-off approach for individuals and business owners that have other priorities. 

IaaS and PaaS are typically reserved for enterprise businesses, startups, or organizations that are scaling quickly. SaaS applications are widely varied and can have both business and personal applications. IaaS and PaaS also allow organizations to maintain some level of control over their systems, runtime, data, and operating systems. SaaS applications are good for startups or small e-commerce businesses that need to launch quickly and lack the resources for independent servers and software development. 

SaaS, PaaS, and IaaS are all forms of cloud computing, but they provide different functionalities and are typically used for different purposes. SaaS is a tool used by end-users to accomplish a task or manage ongoing business processes such as marketing, payroll, billing, learning management, or customer relationship management. PaaS allows businesses to develop applications and deliver via a predetermined platform. IaaS gives organizations the ability to build and manage servers, data, operating systems, and more without the need to physically manage the hardware. There are not many online activities that are not impacted by IaaS, PaaS, and SaaS in cloud computing.
