CLOUD INFRASTRUCTURE MANAGEMENT
Article | October 13, 2021
With the growth of modern technologies, businesses are harnessing the power of cloud computing. Cloud computing is a strategic approach that allows on-demand data computing services over the internet on a pay-as-per-use basis. The storing and accessing of data in the cloud is done from a remote data center. As a result, it regulates the investment in costly hardware for an on-premise setup.
“Cloud computing is an innovative way to run your business.”
- Marc Benioff, Founder, CEO and Chairman, Salesforce.
According to the analysis report by the market intelligence firm ResearchandReport, the global cloud computing market size is projected to reach USD 1,251.09 billion by 2028, recording a CAGR of 19.1%. Amongst the different cloud computing models, the three most vital variants are SaaS, PaaS, and IaaS. This article describes the SaaS vs. PaaS vs. IaaS strategies, their comparison to help you determine the best fit for your business.
The Three Most Vital Cloud Strategies for 2022
But before we begin, let us quickly look upon the interesting statistics on SaaS, PaaS, and IaaS in cloud computing by Statista. It states that the global market size for SaaS is expected to reach 172 billion USD, whereas PaaS and IaaS will reach 101 billion USD and 122 billion USD, respectively, in 2022. Several small-scale, medium-sized, or large-scale enterprises are adopting cloud service models to meet digital transformation. As you plan your workload migration to the cloud, it is vital to understand the ideal strategic model for your business by knowing the details and the difference between SaaS, PaaS, and IaaS.
SaaS (Software as a Service)
SaaS offers on-demand, ready-to-use cloud-based applications to the end-users. It is hosted by a provider and is delivered via the internet on a pay-as-you-go subscription. SaaS applications integrate data from diverse storage locations of an enterprise. SaaS providers keep enhancing their products and ensure that their customers use its latest version every time. Some examples of SaaS platforms are Google Workspace, Dropbox, Salesforce, Cisco WebEx, etc.
Benefits of SaaS
Let us consider a real scenario to explain the advantages of adopting a SaaS computing strategy.
How the University of Sydney Leveraged SaaS (Dropbox) to integrate the processes?
The University of Sydney was facing challenges due to disintegration among its multi-data storage platforms. They needed a unified application that is scalable, user-friendly, and easily accessible across their ecosystem for accelerating their research process.The University of Sydney could securely store and connect data to accelerate the research process by leveraging Dropbox. After implementing Dropbox, the university could significantly establish collaboration between their staff and students and external alliances across the globe. Further, they could control the overhead training and infrastructure cost. Governance also became easy with Dropbox, allowing IT teams to utilize their productive time in other crucial tasks. The scalability and user-friendliness were the primary factors that motivated the university to adopt Dropbox.Referring to the above instance, we can infer that a SaaS model can regulate cost, save time, be user-friendly, and scale as per demand. Further, this model is easy to deploy and maintain that needs minimum focus by the company's technical department.
Drawbacks of SaaS
Every pro comes with a con, and SaaS models are no exceptions.
Performance Reliability: SaaS applications are dependent on the internet, and as a result, they might become inconsistent at times. The only way to avoid this is by investing in a stable and high-speed internet connection. Additionally, you can also use software performance management tools to check the performance of SaaS applications at regular intervals.
Data Security: Data Security is one of the crucial aspects of any organization. SaaS apps lack transparency and the ability to protect business-critical data. As a result, some enterprises dealing with confidential information are in two minds to switch to the software-as-a-service model.
PaaS (Platform as a Service)
PaaS model provides a ready-to-use cloud environment for creating, testing, and maintaining software applications. With the PaaS model, you don’t have to build and maintain the infrastructure required for your application. Examples of PaaS models are Windows Azure, LoadSpring, Google App Engine, Apache Stratos, OpenShift, etc.
Benefits of PaaS
“LoadSpring Cloud Platform is more agile and flexible than other available solutions. We provide cloud solutions to our vendors and partners who want their applications to be SaaS-enabled. Our speed, performance, and seamless integration make it the ideal platform to deploy their apps.”
- Stacey Witt, Chief Marketing Officer at LoadSpring (During an interview with Media 7)
With Stacy’s statement, we can sense how a PaaS model can be helpful for your organization. PaaS is ideal for many medium or large-scale businesses because it provides a ready-to-go solution. All you need is an IT support team to handle the data usage and software. However, with the PaaS model, you have control over the performance of your platform.
Let us explain with an instance.
How Atos Used PaaS (LoadSpring) to Solve the Challenges Faced by Siemens?
At the Gas and Power division of globally recognized brand Siemens, the leaders started experiencing a sloth in their locally hosted P6 and wanted to improve the performance.As an IT support provider for Siemens, Atos assisted them in overcoming the scenario. It referred LoadSpring to assess their P6 cloud-hosting. After sequences of operations, the LoadSpring platform enabled P6 to run 10 times faster than the locally hosted version. This enhanced performance saved an hour per user per week. As a result, Siemens considered their workload migration to LoadSpring that helped them increase their project efficiency.
Drawbacks of PaaS
Here are some of the loopholes to consider while adopting PaaS.
Dependent on Third-Party Vendor: PaaS solutions are vendor-dependent. If you wish to change your existing PaaS model, you may face compatibility issues. It is primarily because all the vendors might not support the same framework to develop and run the applications.
Security Concerns: A potential risk for your application’s back-end data and hosting code may arise because it is stored at the vendors’ site. You should cross-check and verify the security and compliance protocols with your vendor beforehand.
IaaS (Infrastructure as a Service)
IaaS is one of the cloud computing models that provides virtual data centers to medium or large-scale enterprises. It includes the entire infrastructure to research and develop advanced technologies on the cloud. IaaS is a self-service model that hosts website and software solutions and performs data mining and analysis. Examples of popular IaaS models are Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), Cisco Metacloud, etc.
Benefits of IaaS
To understand the advantages of IaaS, let us consider a situation faced by the globally acclaimed OTT platform- Netflix.
How Netflix Depended on IaaS (AWS) For a Scalable and Reliable Infrastructure?
Netflix experienced a momentary surge in viewers and subscribers due to the extreme changes across the world. To accommodate this demand, it needed an infrastructure that could scale simultaneously. As a result, Netflix trusted AWS to help it modernize improved computation, storage, and infrastructure that allow the company to scale rapidly, function steadily, and match up to the capacity needs across the world.
Taking cues from the above example, we can deduce the benefits of using IaaS. IaaS cloud service model is highly scalable, easy to automate and deploy, flexible, and reliable. It also comes under the pay-as-you-go model and hence proves to be cost-efficient as well.
Drawbacks of IaaS
Here are some of the limitations of IaaS that you need to consider.
Train Your People: IaaS model will provide the complete infrastructure for your business, and you need to ensure the smooth running of all the operations. Hence, it becomes inevitable for your team to have thorough knowledge about the deployed model. Otherwise, you might have to face unnecessary hindrances.
Managing Downtime: Enterprises might encounter downtime with IaaS, restricting their access to operational data and applications. As a result, it might affect their process- efficiency for some time.

A technology that has more misinformation around it than anything I have seen before. Much of this bad data is focused on cloud computing.The reality is that it will take a while to roll out 5G. We need to upgrade our phones, cell towers, network devices, and more, and that will not happen overnight. Moreover, the dollars it will require will not be easily extracted from most enterprises.Of course, there are many predictions about how cloud computing will change in a 5G world, most of which are dead wrong. Tech pundits are calling for 5G to light edge computing on fire and take share away from the public clouds. Both will grow rapidly.Any technology change, including 5G, will transform the use of other technologies along with cloud computing. However, what is likely to change is not as disruptive as most 5G fanboys think. Here are two ways 5G will change cloud computing.First, cloud access will spread everywhere. We have bandwidth deserts out there in mostly rural, less populated areas, where access to the Internet is non-existent or sub-10Gb/s down, with 1Gb/s up. You cannot do much with that as a business connected to an IaaS cloud provider; data transfer latency will just be too high. 5G holds the promise of eliminating bandwidth deserts and freeing business now in rural, underserved areas to leverage cloud computing, and thus expand the cloud computing market with 5G.
