What are Cloud Service Models?
Cloud computing services come mainly in three types of service models: SaaS (Software as a Service), IaaS (Infrastructure as a Service), and PaaS (Platform as a Service). Each of the cloud models has its own set of benefits that could serve the needs of various businesses.
Choosing between them requires an understanding of these cloud models, evaluating your requirements, and finding out how the chosen model can deliver your intended set of workflows.
The following is a brief description of the three types of cloud models and their benefits.
1. SaaS
SaaS or Software as a Service is a model that gives quick access to cloud-based web applications. The vendor controls the entire computing stack, which you can access using a web browser. These applications run on the cloud and you can use them by a paid licensed subscription or for free with limited access.
SaaS does not require any installations or downloads in your existing computing infrastructure. This eliminates the need for installing applications on each of your computers with the maintenance and support taken over by the vendor. Some known examples of SaaS include Google G Suite, Microsoft Office 365, Dropbox, etc.
2. IaaS
IaaS or Infrastructure as a Service is basically a virtual provision of computing resources over the cloud. An IaaS cloud provider can give you the entire range of computing infrastructures such as storage, servers, networking hardware alongside maintenance and support.
Businesses can opt for computing resources of their requirement without the need to install hardware on their premises. Amazon Web Services, Microsoft Azure, and Google Compute Engine are some of the leading IaaS cloud service providers.
3. PaaS
Platform as a Service or PaaS is essentially a cloud base where you can develop, test, and organize the different applications for your business. Implementing PaaS simplifies the process of enterprise software development. The virtual runtime environment provided by PaaS gives a favorable space for developing and testing applications.
The entire resources offered in the form of servers, storage, and networking are manageable either by the company or a platform provider. Google App Engine and AWS Elastic Beanstalk are two typical examples of PaaS. PaaS is also subscription-based and gives you flexible pricing options depending on your business requirements.
Adopting Cloud – Choosing Between SaaS, IaaS, and PaaS
Going through the details of what SaaS, PaaS, and IaaS may have given you a general understanding of these three cloud models. Each of them differs and has a range of advantages and disadvantages that may or may not fit in with your business model.
By correlating each of these cloud models side by side, you could derive a conclusion on whether it suits your business requirements.
SaaS
Benefits:
- Affordable – SaaS is affordable as it eliminates the costs involved in the purchase, installation, maintenance, and upgrades of computing hardware.
- Anywhere Accessibility – With SaaS, you can access the services from anywhere using any device such as smartphones, which eliminates the constraints set by on-premise software.
- Ready to Use – You can quickly set up SaaS services so that they become functional in no time. All it takes is that you sign up for the service to get access to fast and powerful computing resources.
Why Should One Opt SaaS?
With SaaS, communication, transferring of content, and scheduling meetings are made easy. SaaS is the ideal choice for small-scale businesses that do not have the necessary budget and resources to deploy on on-premise hardware. Besides, companies that require frequent collaboration on their projects will find SaaS platforms useful.
Studies reveal that Supply Chain Management, Business Intelligence, Enterprise Resource Planning (ERP), and Project and Portfolio Management will see the fastest growth in end-user spending on SaaS applications, through 2022.
Things to Consider Before SaaS Implementation
- Opt for configuration over customization within a SaaS-based delivery model. The configuration will allow you to tailor without changing the core product, whereas, customization will make it challenging to scale with the constant updates and documentation.
- Understand the adoption and usage rates carefully, and set clear objectives to be achieved with the SaaS adoption.
- Compliment your SaaS solution with integrations, and security options to make it more user-initiated.

IaaS
Benefits:
- Minimize Costs – Deploying an IaaS cloud model eliminates the need to deploy on-premise hardware that reduces the costs.
- Enhanced Scalability – As the most flexible cloud computing model, IaaS allows you to scale the computing resources up or down based on demand.
- Simple Deployment – IaaS lets you easily deploy the servers, processing, storage, and networking to make it up and running in no time.
Why Should One Opt IaaS?
IaaS being the most flexible of cloud models gives the best option when it comes to IT hardware infrastructure. IaaS is the right option if you need control over the hardware infrastructure such as managing and customizing according to your requirements.
Whether you are running a startup or a large enterprise, IaaS gives access to computing resources without the need to invest in them separately. However, the only downside with IaaS is that it is much costlier than SaaS or PaaS cloud models.
According to Gartner’s latest report, the worldwide infrastructure-as-a-service (IaaS) market grew 31.3% in 2018 to total $32.4 billion, and in 2019 it’s projected to be worth $38.9 billion. This growth will continue well into 2022, where it’s expected to be worth $76.6 billion.
Things to Consider Before IaaS Implementation
- Clearly define your access needs and the bandwidth of your network to facilitate smooth implementation and function.
- Plan out thorough data storage and security strategy to streamline the process.
- Ensure a disaster recovery plan so that your data remains safe and accessible at all means.
PaaS
Benefits:
- Minimal Development Time – PaaS reduces the development time since the vendor provides all computing resources like server-side components, which simplifies the process and improves the focus of the development team.
- Multiple Programming Language Support – PaaS offers support for multiple programming languages, which a software development company can utilize to build applications for different projects.
- Enhanced Collaboration – With PaaS, your business can benefit from having enhanced collaboration, which will help integrate your team dispersed across various locations.
Why Should One Opt PaaS?
PaaS is the preferred option if your project involves multiple developers and vendors. With PaaS, it is easy to create customized applications as it leases all the essential computing and networking resources. Being a different model, PaaS simplifies the app development process that minimizes your organizational costs.
Besides, it is flexible and delivers the necessary speed in the process, which will rapidly improve your development times. A typical disadvantage with PaaS is that since it is built on virtualized technology, you will have less control over the data processing. In addition, it is also less flexible compared to the IaaS cloud model.
A study by Market Reports World estimates that the global PaaS market will grow at a CAGR of 24.17% during 2019-2023 and will get valued at 28.4 billion USD by the end of 2023.
Things to Consider Before PaaS Implementation
- Crucially analyzing your business needs, decide the automation levels, if it needs to be self-service or fully automated.
- Clearly determine whether to deploy on a private or public cloud.
- Plan through the customization, and efficiency levels.
What Should You Know About DaaS?
Desktop as a Service or DaaS is desktop virtualization provided through the cloud. DaaS is similar to the server deployment done in IaaS. However, it strictly specializes to offer desktop operating systems. As mentioned earlier in this blog, according to Gartner, DaaS is expected to have the most significant growth in the coming years, analyzing the 95.4% increase in Worldwide Public Cloud Service Revenue in 2020.
Providing device accessibility from anywhere and at any time, DaaS enables workforce mobility and enhances flexibility. Its offerings are mostly simple pay-as-a-go subscription models which makes it easy to scale up. With DaaS, an organization can rely on data security, disaster recovery, optimum performance, cost savings, and mobility. Enabling an easy to manage and simplified IT environment for desktop solutions, DaaS is now widely adopted amongst small businesses.
Benefits:
- Security – Along with easy accessibility and simplified management of desktops and applications, DaaS ensures enhanced security of data.
- Flexibility – As mentioned earlier, DaaS enables easy accessibility from anywhere allowing maximum flexibility. Seasonal or remote workers and contract employees can stay productive at all times with streamlined access to applications, remote desktops, and data on any cost-effective device.
- Cost savings – Providing easy monthly and yearly subscription plans, DaaS reduces the capital expense and makes operational expenses more predictable.
- Business continuity – Providing disaster recovery support, and easy access to apps and desktops to the workforce, DaaS helps running a business at all times, even during natural disasters and pandemics.

Businesses, especially small businesses, these days are increasingly adopting cloud service technologies. Why?
It’s the flexibility, scalability and value features of the cloud that are apparently driving this growth in its adoption. The basic aim is to allow employees to work better and promote an efficient work environment, with their offices available everywhere, now that telecommuting is becoming more prevalent as a trend.
Here are some facts that prove how rapidly telecommuting is becoming mainstream:
- By 2020, cloud spending in terms of IT and services is likely to exceed half a trillion dollars.
- 70% of software revenues are based on cloud code – SaaS, PaaS or on-premise as ISV’s base on-premise on cloud platforms.
- Tweet: Almost 50% of large enterprises are looking to double up software and services development staff for cloud projects.
But, as a general fact,
do all businesses stand to gain from using cloud services?
Will all businesses reap equal and extensive benefits from using the cloud?
Is it beneficial for you to use the cloud?
The answer to all these questions depends on the size of the business as well as preferences in terms of data, storage, security and the like.
Before you jump on the bandwagon, you need to analyse your business scenario and your preferences to make an intelligent decision.
Is cloud migration the right way to go for you?
Cloud migration (or moving your apps and services to the cloud), is more of a long term trend. While it may have several benefits of its own, there are several factors that you need to consider before going for it.
When should you consider moving to the cloud?
- If your applications are experiencing an explosive increase in traffic and it is practically difficult for you to scale and arrange resources on the fly, in order to meet the rising demand.
- If you are a software solutions provider and your clients are increasingly demanding faster application development and deployment, and you want to facilitate that while cutting down on infrastructure overheads.
- If your clients are looking to expand their business and diversify geographically and you think it might be a challenge for you to accommodate a multi-region infrastructure system, including its due maintenance, time and human resources.
- If you are looking to reduce your operational costs and increase the effectiveness of your IT.
- If you are looking to set up a disaster recovery system for an entire data center, while still having adequate control over resources and keeping costs under check.
- If you are planning to expand your development team and make it widely distributed so as to allow even remotely located employees to work easily.
These are just some common situations where you could consider cloud migration. There may be more. If you can relate to at least some these, then you can probably start planning.
Small and medium businesses are more likely to be experiencing one or more of the above scenarios. They are the ones who are constantly undergoing rapid and drastic changes in terms of scale, profits and business size. Hence, the obvious features of the cloud like scalability and accessibility can come in very useful.
Large enterprises may have more sustained developments in their business, in which case, they may not necessarily need the cloud. There are other options for them which we’ll be getting into, in a while.
The flipside
Now let’s see some possible consequences that follow cloud migration. You might want to consider the flip side of things as well, before getting into it.
- If your application uses, stores and sends back a lot of sensitive data, then you might not be able to use the cloud. Even compliance regulations restrict you from maintaining such data, in sources like the cloud.
- If you are using proprietary software or technology, and you are looking to move to the cloud, then you have a problem. It might not be legally possible for you to move or deploy such software into the cloud.
- You might have to deal with transparency and control issues, as your hardware is being controlled by someone else.
- You might encounter latency or dormancy issues with certain operations when using the cloud.
- If you want to retain ownership of certain data in your application, then cloud might not be the thing for you. When you migrate your data to the cloud, you have no control of where your data gets stored.
- Shared resources can lead to occasional disturbances in terms of performance and efficiency.
- Your application’s design or architecture might not be suitable as such to fit the cloud architecture. Hence you might need to make certain modifications.
Again, these are only some limitations of cloud migration to get you started on the thinking process. The most common ones are listed above. You may have to deal with other minor issues as and when you migrate.
To make a judgment…
On a normal case, where you already have a setup, which is satisfactory to your employees as well as customers, and you don’t really need much scaling and maintenance at the moment, then you could very well continue as such. It would not be worth these limitations for you to disturb the existing smooth process.
If you are a startup company in the manufacturing industry, it might not be feasible to maintain in-house servers and applications for internal uses. You also might not encounter a lot of the above-mentioned issues as you don’t use the cloud to serve customers directly. In such cases, opting for cloud services might be the best way to go.
For those of you who own large business enterprises in the software industry, it might be better to go for a hybrid model – one which combines the best of cloud services as well as in-house servers or private servers. For applications that involve a lot of sensitive data, or for proprietary software, you could use your own servers, and for other applications, you could use cloud services. That way, you don’t have to compromise on security or data ownership issues while at the same time, attain the flexibility and scalability of the cloud.
You also have the option of private clouds. More on that soon.
The cloud computing model
From a broad perspective, you could go for one out of three cloud computing models – Iaas (Infrastructure as a Service), SaaS (Software as a Service) and PaaS (Platform as a Service).
In case of IaaS models, you don’t have to take care of storage, networking, CDN and virtualization. They can all be left to the IaaS provider.
In PaaS, the application platform, the development, and the database are all handled by the providers.
SaaS models take care of business management, CRM, security as well as tools.
It is important to choose the model once you have decided to for the cloud.
The cloud options
Large enterprises also have the option of choosing a private or a hybrid cloud model.
Private cloud is where you can create your own cloud using specific platforms like Openstack. That way you can access the benefits of the cloud, while still retaining data security and ownership. It is apt for businesses using secure and confidential information and core systems.
A public cloud is where all of your resources are hosted by a separate cloud service provider. It supports more number of customers and is better suited for companies having lesser confidential information, as all the resources are publicly shared and virtualized.
A hybrid cloud model is one in which your resources are spread over private and public clouds. Specific resources can be used in the private cloud, whereas those which do not need a high level of security can be hosted by the public servers. Large software enterprises can benefit from using this model as they can have the best of both worlds. It is a perfect blend of reliability, availability, security and reduced operations costs.
It is extremely important for business enterprises, whether large, medium or small to analyze their business and choose the appropriate cloud solution. If your business scenario demands cloud migration, then your next steps should be in choosing the right model. Once you know exactly what kind of cloud services you need, you can be sure you are doing the right thing.
