What is a Cloud service?
A Cloud service is the collection of a wide range of resources that are provided/delivered to the user over the Internet at any time across the world. It includes services such as registration on the cloud, access, management of data, modification & transfer of files, process & analysis network, etc.
E.g., Data is uploaded to the cloud to scan the malicious files and filter out the clean files by cloud security check.
Different Types of Cloud
Types of Services
IaaS – Infrastructure as a Service
Infrastructure as a Service (IaaS) provides the basic building blocks for cloud IT, such as computing, storage, and networking. IaaS gives you the most control over your cloud environment, but it also requires the most technical expertise to manage.

PaaS – Platform as a Service
Platform as a Service (PaaS) provides a platform for developing, deploying, and managing applications. PaaS takes care of the underlying infrastructure, so you can focus on developing your applications.
SaaS – Software as a Service
Software as a Service (SaaS) provides access to software applications that are hosted in the cloud. SaaS is the most popular type of cloud service, and it is used by businesses of all sizes.
Different Types of Cloud
FaaS – Function as a service
Function as a Service (FaaS) provides a way to run small, isolated pieces of code in the cloud. FaaS is a good choice for event-driven applications and for tasks that need to be executed quickly.
Types of Cloud
Private Cloud: A Private Cloud is a personal cloud of the organization. It is installed in the organization’s server and can be used within the organization’s premises. It is not shared with any other organizations.
E.g., Amazon Virtual Private Cloud, Microsoft Azure, OpenStack, etc.
Public Cloud: A public cloud is a cloud computing environment that multiple organizations share. A third-party provider hosts it, and it is accessible over the Internet.
E.g., Amazon AWS, Microsoft Azure, IBM Cloud, etc.,
Different Types of Cloud
Hybrid Cloud: A hybrid cloud is a cloud computing environment that combines both public cloud and private cloud resources. This allows organizations to take advantage of the benefits of both public and private cloud resources. Organizations share resources privately with a few people from the organization as well as publicly with other organizations.
E.g., AWS Outposts, Azure Stack, Azure Arc, Google Anthos, etc.
Advantages & Disadvantages of Clouds
Private Cloud
Advantages
Security: Private clouds are more secure than public clouds because they are not shared with any other organizations. This makes them a good choice for organizations that need to protect sensitive data.
Compliance: Private clouds can be more compliant with regulations than public clouds. This is because organizations have more control over the security and configuration of their private clouds.
Performance: Private clouds can offer better performance than public clouds because they are not shared with any other organizations. This is important for organizations that need to run demanding applications or that need to guarantee a certain level of performance.
Control: Private clouds give organizations more control over their IT infrastructure. This is important for organizations that want to be able to customize their cloud environment to meet their specific needs.
Different Types of Cloud
Disadvantages
Cost: Private clouds can be more expensive than public clouds. This is because organizations have to pay for the hardware, software, and infrastructure that is used to host their private cloud.
Complexity: Private clouds can be more complex to manage than public clouds. This is because organizations have to manage the entire cloud environment, including the hardware, software, and networking.
Risk: Private clouds can be more risky than public clouds. This is because organizations have more control over their private clouds, which means that they are also responsible for any security or compliance issues that arise.
Public Cloud
Advantages
Cost-effectiveness: Public clouds can be more cost-effective than on-premises IT infrastructure. This is because cloud providers can take advantage of economies of scale and pass on the savings to their customers.
Scalability: Public clouds can be scaled up or down as needed, which makes them a good choice for organizations with fluctuating workloads.
Flexibility: Public clouds offer a wide range of services, which gives organizations the flexibility to choose the services that they need.
Security: Public cloud providers invest heavily in security, and they have a team of experts who are constantly working to protect their customers’ data.
Innovation: Public cloud providers are constantly innovating, and they offer a wide range of new services that can help organizations improve their operations.
Disadvantages
Security: Public clouds are not as secure as private clouds because they are shared with multiple organizations. This means that there is a risk of data breaches and other security incidents.
Compliance: Public clouds can be complex to manage from a compliance perspective. Organizations need to ensure that they are compliant with all applicable laws and regulations, including those related to data privacy, security, and intellectual property.
Vendor lock-in: Organizations that rely on a single public cloud provider may be at risk of vendor lock-in. This means that they may be unable to switch to a different provider if they are not happy with the service or if the provider goes out of business.
Performance: Public clouds can be affected by factors such as network latency and the availability of resources. Organizations need to ensure that their cloud applications are designed to be scalable and resilient to performance issues.
Different Types of Cloud
Hybrid Cloud
Advantages
Cost-effectiveness: Hybrid clouds can be more cost-effective than public clouds or private clouds alone. This is because organizations can use the public cloud for resources that are not critical, and they can use the private cloud for resources that need to be more secure or compliant.
Scalability: Hybrid clouds can be scaled up or down as needed, which makes them a good choice for organizations with fluctuating workloads.
Flexibility: Hybrid clouds offer a wide range of services, which gives organizations the flexibility to choose the services that they need.
Security: Hybrid clouds can be more secure than public clouds or private clouds alone. This is because organizations can use the security features of both public and private clouds.
Compliance: Hybrid clouds can be more compliant with regulations than public clouds or private clouds alone. This is because organizations can choose the cloud services that are most compliant with their specific regulations.
Different Types of Cloud
Disadvantages
Complexity: Hybrid clouds can be more complex to manage than public clouds or private clouds alone. This is because organizations need to manage both the public and private cloud environments.
Cost: Hybrid clouds can be more expensive than public clouds or private clouds alone. This is because organizations need to pay for the resources that they use in both the public and private cloud environments.
Vendor lock-in: Organizations that use multiple cloud providers may be at risk of vendor lock-in. This means that they may be unable to switch to a different provider if they are not happy with the service or if the provider goes out of business. This end-up the organization stuck in the business’s regular activities.
Benefits of Cloud Computing
Lower-cost Computers for Users
Since the Cloud is a server based on the Internet, the data stored by the user in the Cloud is online on the Internet. Therefore, to run the Cloud, users do not need any high-specification desktop PC, because everything runs on a web-based Cloud. Hence the user computers in cloud computing can be lower priced, with smaller hard disks, less memory; more efficient processors, and the like.
Improved Performance
A desktop PC does not have to store and run a ton of software-based applications. (The apps are run from the cloud, instead.) With fewer bloated programs hogging the computer’s memory, users will see better performance from their PCs. Put simply computers in a cloud computing system will boot up faster and run faster because they will have fewer programs and processes loaded into memory.
Lower IT Infrastructure Costs
In a larger organization, the IT department could also see lower costs from the adoption of cloud computing. Instead of investing in larger numbers of more powerful servers, the organization can use the computing power of the cloud to supplement or replace internal computing resources.
Fewer Maintenance Issues
Cloud computing greatly reduces both hardware and software maintenance for organizations of all sizes. First, with the hardware with fewer servers necessary in the organization, maintenance costs are immediately lowered. As to software maintenance, remember that all cloud apps are based elsewhere, so there’s no software on the organization’s computers for the IT employees to maintain.
Instant Software Updates
The users are no longer faced with the choice between obsolete software and high upgrade costs. When the app is web-based, updates happen automatically and are available the next time the user logs in to the cloud. Whenever one accesses a web-based application, one is getting the latest version without needing to pay for or download an upgrade.

Challenges of Cloud Computing
Requires a Constant Internet Connection
Cloud computing is, quite simply, impossible if one cannot connect to the Internet. Because one uses the Internet to connect to both applications and documents, if one does not have an Internet connection, one cannot access anything. A dead Internet connection means no work or is inherently unreliable, this could be a deal breaker. When one is offline, cloud computing just does not work.
Low-Speed Connections
Similarly, a low-speed Internet connection makes cloud computing painful at best and often impossible. Web-based apps often require a lot of speed to download, as do large documents. If one is fighting with a low speed, it might take seemingly forever just to change from page to page in a document, let alone launch a feature-rich cloud service.
Futures Might Be Limited
This particular disadvantage is bound to change, but today many web-based applications simply are not as full-featured as their desktop-based version. For example, the feature set of Google Presentations with that of Microsoft PowerPoint; there is just a lot more one can do with PowerPoint than one can with Google’s web-based offering. The basics are similar, but the cloud application lacks many of PowerPoint’s advanced features.
Data is not Secured
Cloud means an online server on the Internet. The user stores data on the cloud means, on an online server on the Internet. What is the guarantee of not accessing the data stored on the cloud by any unauthorized person or third party? This is a worthy question since anything on the internet means is not been secured for a long time.
Cloud Loses Data
The data stored in the Cloud can be accessed from anywhere with any device. Cloud provides the fastest delivery of stored data to the user at the earliest. Since the Cloud is safe and secure for different devices but what could be the loss of data, if there is no physical backup (Pendrive, HDD) found.
