What are the Different Types of Cloud Computing Services?
Table of Contents
With the global popularity of cloud computing and services in the business world, almost every organization is moving away from the traditional on-premise services they have come to rely on to cloud-based services. Cloud is though “as-a-service” types are increasing every day, there are four crucial models of cloud services to compare:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
IaaS is focused mainly on data centers, networks, firewalls, servers, and storage, while PaaS adds various developer tools and operating systems.
However, SaaS is the most comprehensive of the three, incorporating aspects of IaaS and PaaS. FaaS is in a different league of its own. Before we understand the types of cloud computing services, let’s understand what cloud computing is.
What is Cloud Computing?
Cloud solutions is an abstraction of computation, storage, and network infrastructure put together as a platform that allows for speedy application deployment and dynamic scaling. In addition, self-service is crucial to cloud computing since it allows users to quickly and easily get started by filling out a web form.
It’s located someplace at the other end of your internet connection, where you may access apps and services and safely store your data. Small company owners must be able to access data and apps from their PCs, tablets, or mobile phones, whether in the office, out in the field, or on the road in today’s dynamic business environment.
This access is made possible via cloud computing and an internet connection. So even if you’re unaware, you already use cloud computing. In addition, cloud computing solutions makes it possible behind the scenes for you to exchange emails, collaborate on documents, save files, and stream videos using online services like Gmail or Outlook 365.
Cloud backup services are failsafe answers if your business loses data due to a server disaster, a cyberattack, or another event. The top cloud service providers offer services which include storage, synchronization, and restoration of lost or deleted data, real-time backups, archiving, and high levels of security.
Numerous cloud service providers offer cloud backup capabilities as well. Email services, application hosting, web-based phone systems, and data storage are just a few of the information exchange methods made possible by cloud hosting services. Your company website can be hosted by cloud service providers, which can also handle databases and store domain names. Cloud hosting services are remote, making it simple to scale up to handle peak traffic.
What are the Different Types of Cloud Computing Services?
As you explore moving your business to the cloud, whether for application or infrastructure deployment – it’s more critical than ever to understand the differences and benefits of cloud computing solutions. Surveys say that there are three leading cloud service platforms available today – SaaS, PaaS, and IaaS – that have grown significantly worldwide. Their revenue increased from around $90 billion in 2016 to more than $312 billion in 2020.
Cloud solutions replace on-premises infrastructure with cloud computing infrastructure and has become a new business norm. Our team at Veritis has given a very detailed description of each delivery option. The insights in the article will get you an answer to the most pressing question today – which is the exemplary cloud service for your business among cloud solutions?
Not so long ago, most companies used to run their systems on-site, when clouds were just the white fluffy things in the sky. Today, any business can rely on cloud computing infrastructure for almost all its systems and processes. However, each cloud service model has its benefits; thus, it is crucial to recognize which model is the right fit for you.
SaaS, sometimes referred to as cloud application services, is one of the most well-liked types of cloud computing services and is frequently utilized by individuals and businesses regularly. SaaS is the most straightforward approach to keep up with the three.
The best part about SaaS is that anyone can utilize it without needing to be an IT pro or developer. It is very scalable and straightforward to use and operate. With SaaS, the program or application is ready in a few hours after you provision a server, for instance, in cloud solutions.
SaaS is at the top of the IT stack and has the highest level of abstraction, providing all the layers in the stack, in contrast to other cloud computing service models. In summary, SaaS is a revolutionary means of providing software and apps over the internet through a subscription model. Some well-known SaaS tools are Google Apps, MailChimp, and Hubspot.
The widespread use of SaaS apps can be attributed to benefits of cloud computing. First, they may be accessed from any computer or mobile device with an internet connection, which is the first advantage. Second, SaaS companies provide a variety of readily available, simple to set up and use off-the-shelf solutions. Therefore, whether it’s a simple bundle or a more involved solution, there’s something for everyone.
As vendors handle technological challenges like data, servers, and storage, cost reduction and time savings are interconnected. Businesses can use this to reduce costs and give their technical personnel more time to work on significant projects.
There are certain drawbacks to SaaS, though. Applications that rely on the internet may occasionally experience performance issues when they are run from distant data centers. Apps already installed on your staff members’ PCs might work considerably better in this scenario. You should spend money on a dependable and quick internet connection to avoid these problems. The performance of SaaS apps should also be monitored over time by the cloud computing service providers.
Insufficient data protection is One of the main reasons some businesses are hesitant to transition to the software-as-a-service cloud computing service model. Think twice before outsourcing access control to a third-party service provider because it now becomes your top priority.
A cloud computing architecture known as Platform as a Service (PaaS) allows customers to build, develop, run, and manage their applications using the environment of a different cloud provider.
In a PaaS approach, the vendor typically provides developers with complete infrastructure, including hardware and software. As a result, customers can avoid spending money on expensive cloud computing infrastructure, software licensing, and development tools.
You can save time and money using PaaS solutions rather than creating cloud solutions from scratch. Thanks to the prebuilt back-end cloud computing infrastructure, your cloud solution can be quickly prototyped and developed. In addition, you can access a variety of libraries, frameworks, templates, and other tools from PaaS vendors, which shortens the time needed for development. All of these tools contribute to the development process’s acceleration and simplification.
PaaS also comes along with its drawbacks, like SaaS. When employing PaaS solutions, runtime problems might be a significant problem in cloud computing applications. You can experience issues if the programming languages and frameworks you intend to use are incompatible with the PaaS or if a specific version of a framework is not accessible. Additionally, you can run into cloud computing solutions problems if the PaaS provider makes modifications to their design that conflict with your efforts.
For legacy systems, customization is lacking. As a result, you might find that your previous apps or services don’t function well with PaaS solutions. Unfortunately, you’ll have to spend money on customizing and setup modifications to fix this issue.
Along with SaaS and PaaS, IaaS is one of the three primary cloud computing services that offer computer resources via the internet. With IaaS, a third party makes infrastructure resources—like storage, servers, and networking resources—typically located in on-premises data centers available on a pay-per-use basis. As a result, IaaS requires the most expenditure and reliance on the cloud service providers compared to the other two types. Therefore, it is better to adopt this platform when you are running aground on funds and relying on big data.
IaaS houses various benefits of cloud computing. Saving money is a significant advantage of adopting IaaS. You can save money on cloud computing infrastructure management by outsourcing to a third party that will take care of hardware and software upgrades, maintenance, and repairs. IaaS offers companies a dependable service unaffected by outages or hardware breakdowns. As a result, businesses can concentrate on their core competencies without worrying about their infrastructure. IaaS is renowned for its scalability; providers may alter the size of their cloud service infrastructure by demand.
However, IaaS has its disadvantages. Despite being easily expandable, you should expect unpredictably high expenses, mostly because instances are not shut down promptly. In addition, it’s possible for cloud service providers to be rigid and neglect to update their software often. As a result, the firm, not the cloud service provider, is in charge of performing software upgrades. Additionally, security is a worry when utilizing third-party services; it is crucial to review the service level agreement of cloud service providers to learn about the security precautions in place.
A cloud service model called “Function-as-a-Service,” or “FaaS,” enables developers to create, compute, operate, and manage application packages as functions without keeping up with their infrastructure.
These functions use a FaaS provider’s services to handle server-side logic and state in an event-driven execution architecture that operates in stateless containers. FaaS solutions are accessible on popular public clouds and may be installed on-premise, giving business IT for app development critical new features. To get ready to adopt a serverless strategy with FaaS, get the cloud-native strategy guide. Then, developers create a business logic run in Linux containers entirely controlled by a platform as part of a serverless cloud computing solutions called FaaS.
While the concept is typically a cloud computing platform leveraging cloud computing services, it is increasingly used for on-premises and cloud deployment models. One option to create an app with a serverless architecture is using a FaaS model; however, as the serverless paradigm gains popularity, developers are searching for solutions that enable the creation of serverless microservices and stateless containers.
Developers are provided with an abstraction by FaaS to launch web applications in response to events without having to manage servers. For instance, uploading a file may cause custom code to transcode it into several formats.
What are the Types of Deployment Models in Cloud Computing?
Private, public, hybrid, and multi-clouds are the four primary sub types of cloud computing services. In addition, infrastructure-as-a-Service (IaaS), platforms-as-a-Service (PaaS), and software-as-a-service are the three primary categories of cloud computing services (SaaS).
A unique choice is making a cloud type or cloud service. Even though they are similar, no two clouds are alike, and no two cloud services are employed to address the same issue. But by recognizing the parallels, you can better understand how the limitations of each type of cloud computing and cloud service could affect your company.
Public clouds are cloud computing environments that are frequently built using IT infrastructure that is not the end user’s. Alibaba Cloud, Amazon Web Services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure are a few of the most significant public cloud service providers.
Public cloud Services in the past have always operated off-site, but today’s public cloud providers have begun to deliver cloud services to clients’ on-site data centers. Locational and ownership distinctions are now irrelevant as a result.
When the environments are divided and dispersed to several tenants, all clouds become public clouds. In addition, since some cloud providers permit tenants to utilize their clouds for free, fee structures are no longer necessary for public clouds.
Private cloud computing is a cloud environment wholly dedicated to one end user or group, often running behind that user’s or group’s firewall. When the underlying IT infrastructure is devoted to a single client with totally segregated access, all clouds become private clouds.
However, private cloud computing is no longer required to be powered by on-site IT equipment. Now that businesses are constructing private cloud solutions in off-site, rented data centers operated by vendors, all standards governing location and ownership are irrelevant.
A private cloud is a third-party provider that deploys, configures, and manages a private cloud that customers build and utilize. Enterprises with understaffed or underqualified IT teams can improve the quality of their private cloud computing solutions and infrastructure by using managed private cloud computing solutions as a cloud deployment option.
A hybrid cloud is an IT environment comprising several environments that appear to be linked through local area networks, wide area networks, VPNs, and APIs to form a single, unified environment.
Depending on who you ask, the criteria for hybrid clouds might vary, and their features can be complicated. When programs may enter and exit several distinct—yet connected—environments, every IT system turns into a hybrid cloud. These environments must be derived from centralized IT resources that can grow as needed, at the very least. And a platform for integrated management and orchestration must be used to manage each of those environments as a single.
Data is moved between highly secure private cloud networks and less secure public cloud networks in a hybrid cloud computing environment. Unfortunately, this frequently puts data and compliance at risk. As a result, regulations for data security, such as GDPR, have been introduced, making people more conscious of the need to abide by the law.
Therefore, businesses must take extra measures to ensure compliance standards are satisfied. Ensure the data transmission mechanism complies with all relevant legal requirements and that the public and private cloud networks follow industry standards like GDPR. If a data center’s capabilities are constrained, it is crucial to have a well-defined data redundancy strategy to assure timely backup of crucial data. Hosting numerous data centers from one or more cloud service providers can do this. This will be beneficial in the event of data center disruptions.
Multi-cloud has recently generated a lot of attention in the cloud solutions arena. Despite several similarities that lead to frequent confusion with hybrid clouds, there are still some critical differences between the two.
While multi-cloud is a mix-and-match arrangement of cloud services from several service providers tailored to specific workload requirements, a hybrid cloud is an amalgamation of on-premises private and external public clouds. In other terms, multi-cloud is a hybrid cloud technology that utilizes many public cloud infrastructures. According to recent studies, private cloud computing usage among businesses has dropped from 77% to 72% over the previous year as the commercial cloud computing focus switches to the public cloud.
Multiple strategic advantages are possible with a multi-cloud approach. Businesses relying only on one cloud service provider may experience challenges like cloud data center outages or bandwidth problems, which might hurt their operations and even cause them to lose clients. This is especially true when some of their essential apps are involved. Utilizing a variety of cloud services guarantees that the risk of downtime and data loss is minimized even if one or more software, hardware, network, etc., components fail.
A multi-cloud approach also gives businesses the adaptability to particularly meet the varying needs of the many business operations, teams, and departments. These can include the cloud’s security, privacy, performance, or geographic reach.
Companies’ IT decision-makers are reviewing their cloud plans due to the increasing reliance on multi-cloud environments. The main element affecting an organization’s cloud investment is cost optimization. Two-fifths of IT executives don’t know how much money their organizations spend on the cloud, though.
According to a recent global poll, 45 percent of respondents saw cost reduction as the main benefit of using services from several cloud service providers. Similarly, 40% of respondents support risk minimization, while 44% are motivated by the need to preserve agility in their firms.
The main issues with managing multi-cloud settings are implementing security and governance regulations, automation, cloud consumption prices, and resource usage optimization. Over the next two to three years, security will continue to be the top investment priority for IT decision-makers due to the demand for distributed and virtual infrastructure. Organizations may take the first step toward managing their multi-cloud systems by evaluating their cloud assets and clearly understanding their cloud expenses.
IT executives are advised by experts to modify their management strategy using new technological solutions that make use of AI and machine learning to lessen the complexity caused by multi-cloud.

Cloud Disaster Recovery Services
Cloud disaster recovery (CDR) is a managed cloud solution that gives you remote access to your systems in a secure virtual environment and aids in the speedy recovery of your organization’s essential systems following a disaster.
Managing a backup data center may be time-consuming and expensive with standard DR. Cloud disaster recovery services has completely revolutionized traditional DR. IT teams may now use the cloud’s instant spin-up and fail-over capabilities by removing the requirement for conventional infrastructure and drastically lowering downtime. As a result, recuperation times are shortened, and costs are reduced.
Disaster recovery in the cloud follows a very different methodology than traditional DR. Cloud disaster recovery encapsulates the entire server, including the operating system, applications, patches, and data, into a single software bundle or a virtual server rather than loading the servers with the OS and application software and patching the most recent configuration used in production. The virtual server is then quickly started on a virtual host, cloned, or backed up to an offshore data center. The operating system, programs, patches, and data may be moved from one data center to another considerably quicker than typical DR strategies since the virtual server is not dependent on hardware.
