With a range of network and computing capabilities now offered via the cloud, it can be tricky to keep up. We explain the four core 'as a service' offerings and their use cases.
Adoption of cloud has grown rapidly in the past several years. According to Gartner®, Worldwide end-user spending on public cloud services is forecast to grow 20.7% to total $591.8 billion in 2023, up from $490.3 billion in 2022. What started out as a simpler choice between “on-premises” and “cloud” has expanded into countless offerings that serve various use cases.
“As a service” or “aaS” is the general catch-all for cloud offerings, categorized by acronyms that can often blur into one another. Four commonly used services are:
For companies struggling to make sense of it all, and wanting to find greater efficiencies in a challenging and competitive market, the question remains: Which service or combination of services is the right one for my business?
This blog will explain the difference between each of these four offerings and provide suggestions on how to leverage these technologies depending on which industry you’re in and how your business operates.
Before we dive into the deep end, we need to get one thing out of the way: What exactly is an “as a service” model?
Simply put, “as a service” means you are renting or subscribing to technology, hardware, and/or infrastructure rather than owning it. This is because the service provider owns and manages it for you. The service can also include software, network access, applications, and tools.
“As a service” is a more recent development in the history of computing. The technology is all accessed through a browser or portal and gives users immediate, on-demand access to capabilities without the hefty price tag and logistics often associated with traditional deployments.
Platform as a Service (PaaS) brings development and deployment to the cloud. Solutions enable companies to deliver everything from simple cloud-based services to complex, cloud-powered enterprise applications. Companies choose the resources they need from a PaaS provider on a subscription basis, and they are usually off and running immediately.
Like IaaS, PaaS includes infrastructure like compute, storage and networking, but with the tools, business intelligence (BI) services, and database management systems needed to do development in the cloud. PaaS supports the complete application lifecycle: Building, testing, deploying, managing, and updating.
PaaS is recommended for startups and smaller businesses. Whether you are working on digital transformation for government services or need a better way to manage your remote workforce, PaaS gives you direct, immediate access to best-of-breed resources without the hefty price tag and the time spent trying to make sure the software plays well with incumbent systems.
The bottom line is PaaS allows you to bypass the complexity and cost of managing application infrastructure, middleware, software licenses, and container orchestrators. With PaaS, you manage the applications you develop, and the PaaS provider takes care of everything else.
The result is a level playing field where agile, cloud-based companies compete with the largest incumbent solutions.
Software as a Service (SaaS) is software without licenses and without the maintenance hassle. Companies subscribe to the software on a monthly or annual subscription basis. Some are also free – in exchange for access to your usage data. Enterprises opting for SaaS may go through an independent software vendor (ISV), who utilizes a third-party cloud provider to host the application, or through a larger company such as Microsoft, in which the cloud provider is also be the software vendor.
The SaaS provider then manages application access, as well as the security and performance. This solution means your enterprise’s SaaS applications—whether that’s Salesforce or Slack—run on the providers’ servers, with no need to install or maintain software on-premises.
SaaS is recommended for everyone. Organizations big and small benefit from not having to worry about lengthy implementation or being locked-in to years of maintenance, upgrades, and support contracts.
Also, from an organizational perspective, SaaS gives companies flexibility as they grow and reduces the technical debt of IT teams to support and update the latest releases.
Infrastructure as a Service (or IaaS) is the new name for what used to be called “enterprise cloud.” Rather than ordering servers, waiting for them to be configured and connected, users simply rent or lease servers in the cloud.
As a full-service offering, IaaS combines storage, compute, and networking on demand, priced on a pay-as-you-go basis. Amazon Web Services (AWS), Microsoft Azure, and Google Cloud are the most well-known IaaS providers.
IaaS solutions are popular because they allow companies to scale network resources up or down, depending on bandwidth and usage needs. They also enable quick provisioning of applications and allow companies to save money on hardware and avoid the costs traditionally associated with on-premises networking.
IaaS is recommended for companies that have dynamic networking needs. Companies in retail, entertainment, and sports, for example, often have network needs that can change rapidly and whose IT teams would benefit from a solution that consolidates all networking into a single, extensible offering.
According to Gartner VP Analyst Sid Nag, “Emerging technologies that can help businesses bring experiences closer to their customers, such as the metaverse, chatbots and digital twins, will require hyperscale infrastructure to meet growing demands for compute and storage power.”
These needs include AI and any other business functions that leverage data in an intelligent way and are driven by customer experience.
The bottom line here is that no matter which business you’re in, IaaS enables you to cut right through the complexity and cost of managing networks and network infrastructure. Each solution is managed as a separate service, and the company only pays for when it needs the service.
Network as a Service (NaaS) is a solution that combines IaaS with network and security services like unified threat management (UTM) and load balancing. For anyone who might already be confused, NaaS is simply IaaS minus compute and storage. As its name suggests, it is for networking only, and networking functionality is delivered via the cloud.
Companies can benefit from NaaS because it enables them to avoid the complex headaches that can come from networking, as well as reduce the operating expenses (OpEx) for network licenses, hardware, software, and management tools.
NaaS is recommended for companies struggling with recurring capital costs, skill shortages, and the increased complexity of remote access for employees and managing multiple cloud environments. It also provides a secure and reliable private network for protected transfer of data and reduced latency and bottlenecks, something that the public internet cannot guarantee.
NaaS leaves networking hassle to the professionals, and gives you immediate access to reduced network costs, proactive maintenance, enhanced security, optimized systems, and improved quality of service.
Selecting the right cloud service model depends on your business needs, budget, and IT resources. Each “as a Service” model—whether IaaS, NaaS, PaaS, or SaaS—offers specific benefits and is suited to different use cases.
To choose the best solution for your organization:
Assess Your Business Needs:
Consider Scalability and Flexibility:
Focus on Integration:
Evaluate Long-Term Costs:
Security and Compliance:
Ultimately, most companies opt for a multicloud or hybrid approach. By combining different cloud services, businesses can create a custom solution that leverages the strengths of IaaS, PaaS, NaaS, and SaaS, aligning with their goals while optimizing cost and performance.
