Types of Cloud Services: IaaS vs. SaaS vs. PaaS

IaaS, PaaS, and SaaS are the types of cloud services that help businesses transform their digital experience while reducing the infrastructural costs in turn. All these cloud services differ primarily in what they offer to the end user. Each cloud service has its benefits depending upon the business and functional requirements.

Here is a breakdown of cloud services: Iaas vs. PaaS vs. SaaS.

1. Software as a Service (SaaS)

SaaS/ software as a service refers to cloud-based applications, often developed by a SaaS development company. These applications are hosted online by a company that makes them available for purchase on a pay-as-you-go pricing model.

The global SaaS market will be worth $186 billion by 2022 and is expected to reach $344.3 billion by 2028 with a CAGR of 11.0%. Grand View Research

Key Reasons Businesses Should Adopt SaaS Business Model

Adopting a SaaS Business model provides many benefits over traditional on-premise software installations. Some of them are as follows:

  • Speed of Innovation
  • Reduced Marketing Efforts
  • Faster Time to Market
  • Reduced Churn Rates
  • The Anytime, Anywhere Model

2. Platform as a Service (PaaS)

PaaS/ platform as a service refers to a cloud-based platform that offers a robust framework for developers to build, test, and manage new custom applications. Unlike SaaS, it does not provide software over the Internet; instead, it offers the platform to businesses where the software is being built. Google App Engine and OpenShift are common PaaS examples.

The global PaaS market will be worth $74.5 billion in 2022 and is expected to reach $206.30 billion by 2028 with a CAGR of 19.0%. – Grand View Research

Why should I adopt the PaaS business model?

With PaaS, businesses can quickly deploy, run, and manage custom cloud applications without building and maintaining their own servers and infrastructure.

3. Infrastructure as a Service (IaaS)

IaaS/ infrastructure as a service refers to a cloud-based infrastructure service that offers virtual data centers to businesses, which help them build and manage their operating systems, servers, data storage, and network infrastructure. The common IaaS examples are Microsoft Azure and Amazon Web Services (AWS).

The global IaaS market is worth $115.74 billion in 2022 and is expected to reach $150.25 billion by 2023. Grand View Research

Why should I adopt the IaaS business model?

  • IaaS is easy to access and can be customized to meet your business needs.
  • You get the storage, backup, and recovery of all essential data. It means you don’t have to worry about finding a storage space or investing in data management or maintenance. This significantly reduces costs.

Types of Cloud Deployment: Public vs Private vs Hybrid Cloud

A single type of cloud computing is not fit for every business requirement. There are different cloud deployment models and services, which have evolved with time to offer the right solution for every disparate business needs. Thus, before going into the process of cloud migration, it is essential to determine the types of cloud deployment — Public Cloud, Private Cloud, and Hybrid Cloud.
types of cloud

1. Public Cloud

Public clouds are operated and owned by third-party providers. In the case of a public cloud, the services offered by cloud providers are over a network that is open for public use, implying that an organization shares the same hardware and network devices with other companies of the same cloud service provider. Microsoft Azure is an example of a public cloud.

2. Private Cloud

A private cloud is a deployment model exclusively used by a single organization. In the case of a private cloud, the services and infrastructure are maintained on a private network, either located physically at the organization’s on-site data center or hosted by third-party service providers.

3. Hybrid Cloud

The combination of private and public clouds gives rise to a hybrid cloud, allowing the sharing of data and applications between both of them. Using a hybrid cloud deployment model enables businesses to move applications and data between public and private clouds, leading to an agile, secure, and flexible digital business model.

Benefits of Cloud Computing

The rate at which data is exploding has pushed digital businesses to embrace cloud computing as the platform for innovation. Enterprises across all industries are leveraging cloud solutions for various use cases, like digital security, disaster recovery, big data analytics, and data backup.

Difference between cloud strategy and cloud migration

Cloud Strategy

Cloud is a buzzword, but 37% of cloud migrations fail. Big brands like Twitter and Pinterest have experienced a cloud migration failure. TSB witnessed a cloud migration fiasco, forcing them to increase interest payments to cover customer losses. Why?

“Good tactics can save even the worst strategy. Bad tactics will destroy even the best strategy.”
– General George S. Patton Jr.

One of the key reasons for cloud migration failure is the business’s inability to frame out a cloud strategy before embarking on a cloud migration journey. There are a few necessary steps that every enterprise cloud strategy should follow.

  • Creating an Enterprise Cloud Strategy Team
  • Analyzing Applications Thoroughly
  • Building A Hybrid Cloud Strategy Roadmap
  • Reskilling and Upskilling
  • Implementation

Cloud Migration

On their road to digital transformation, organizations face various challenges — digital security, digital vision & strategy, and organization readiness. To navigate these digital transformation challenges, businesses are turning towards cloud solutions.

However, organizations face many complications when they begin their cloud migration journey. One of the common questions regarding cloud migration is, “How do we even start?”
the roadblock to successful cloud migration

Following are the 5 R in cloud migration strategy that helps businesses embark on a successful journey.

  • Rehost
  • Refactor
  • Revise
  • Rebuild
  • Replace

Cloud computing use cases

1. Serverless computing

The serverless computing approach takes the complete worry of setting up, managing, and maintaining resources off users’ shoulders. Vendors take care of everything, such as bandwidth allocation, software updates, and scalability. AWS, GCP, and Microsoft Azure are typical examples of serverless computing.

2. AI-as-a-Service (AIaaS)

Earlier artificial intelligence was accessible only to cash-rich businesses. The machines were expensive, AI programmers were in short supply, and companies didn’t have enough budget for hiring specialized talent and building AI capabilities into their infrastructure.

However, the AI-as-a-service (AIaaS) approach is completely changing the game. You can easily access fully managed AI and machine learning frameworks by paying a fee. It means you can access advanced infrastructure at a fraction of the cost or even scale them based on your business requirements.

3. Fault-tolerant systems

Even the most successful businesses took a hit at some point. However, Cloud computing can help you create fault-tolerant systems that withstand the test of time and ensure your operations never go down.

Netflix is a famous example. In 2008, it suffered a massive setback when database corruption affected its DVD shipments. Learning from the experience, the media streaming platform switched to cloud servers. These cloud servers duplicate data through multiple clusters to ensure it keeps operating even if one server goes down for some reason.

4. Scalable applications

Scaling a mobile application was a big challenge before. But with cloud computing, you can quickly build high-performance applications that you can easily host and scale on the cloud. This reduces the turnaround time for startups looking to raise funds and offers them the advantage of being first over their competitors.

What are the limitations of Cloud Computing?

Like other technologies in the IT industry, Cloud Computing isn’t picture-perfect. It has some limitations, despite the compelling benefits. As a newbie cloud computing enthusiast, you must be aware of them:

  • Cloud computing has limited customization options. You will get repurposable templates that make your life easier, but you can only go this far. You need to depend upon your cloud provider to want anything specific.
  • Cloud providers have complete control over the moderation policies of the platform. Without a regulatory understanding, you’ll have little control over the terms and conditions of the SLA. It may also hamper productivity or limit you in areas like data privacy, confidentiality, or technical limitations of the cloud provider.
  • Even if you have developed and hosted applications on the cloud, you’ll only have partial control over them. Cloud providers will still control the app as they own the platform that hosts them.

What is the future of Cloud Computing?

We learned what Cloud computing looks like today and how businesses can benefit from it. But what does it have in store for the future?

1. Data will be processed much faster with edge computing

With a sudden spike in devices interconnected with the Internet of Things (IoT), there’s immense pressure on cloud service providers to process it faster. These providers are tackling it with edge computing, a new yet high-efficient cloud computing technique in which we process data locally as close as possible to the source of the network.

Since data doesn’t have to travel faster, processing it will be faster and easier. As a result, edge computing has become a mainstream trend, with a market worth $40.84 million.

2. Security becomes a priority with DevSecOps

Given the insane number of cloud computing risks like data theft, man-in-the-middle attacks, and denial of service attacks – data security is a significant concern for businesses hosting their assets on the cloud.

To overcome this, they use the DevSecOps approach to build security into the data pipeline right from the beginning. Many businesses see it as a game changer that can improve security levels in the cloud.

3. Using service mesh to foster secure communication between security layers

As businesses are creating robust enterprise applications using radical approaches like the microservice architecture, it is essential to ensure that individual services can securely communicate. Businesses are providing this by implementing service mesh, a platform layer on top of the infrastructure layer that aims to secure the communication channels between security layers. It plays a critical role in provisioning access to cloud tenants.

4. Cloud computing will lead to widespread AI adoption

Cloud computing is a key enabler for widespread AI adoption. – IBM

Every business looking to improve must include AI in its business processes. It is because some operations require 24×7 monitoring, and humans can never match the perfection of AI.

Cloud-centric ecosystems are integral to implementing these AI solutions because their cognitive abilities thrive on a large volume of data, which you can easily access on cloud computing ecosystems.

5. Open-source cloud ecosystems will come into prominence

While private cloud networks make up a large share of the cloud computing ecosystem, they’re often restrictive regarding features. That’s why most businesses are now moving towards open-source clouds built with free-to-access toolkits. The best part about these ecosystems is that you can easily customize them based on your business needs and use them without predefined limitations.
