Types of Cloud Computing

Cloud computing is Internet-based computing in which a shared pool of resources is available over broad network access, these resources can be provisioned or released with minimum management efforts and service-provider interaction. In this article, we going to cover what is cloud computing, types of cloud Services, Deployment Models, and Types of Cloud Services. 

What Is Cloud Computing?

Cloud computing is a transforming way of business operations by offering scalable and flexible computing resources over the Internet. It facilitates organizations to access data, applications, and services from anywhere, at any time, resulting in increased efficiency and cost-effectiveness. Cloud computing makes free from the need for on-premises infrastructure and lets to empowers businesses to focus on innovation and growth rather than managing IT hardware.

What are the different types is are of Cloud Computing ?

Cloud Computing is includes include the cloud type such as Infrastructure as a Service (IaaS ) , Platform as a Service (PaaS ), and Software as a Service ( SaaS ). In this IaaS provides virtualized computing resources, PaaS provides development and deployment platforms and SaaS provides software applications over the internet . These services are complemented by various deployment models such as public, private, hybrid and multiclouddiverse business need and preference .

Types Of Cloud Computing Models

In general, Cloud Computing Models are widely classified into 4 types. They are as follows:

1 . IaaS ( Infrastructure as a Service )

• It is provides provide scalable and virtualized computing resource like server , storage , and network over theinternet .
• In this service , users is have can have full control over the infrastructure , have customization and management access ofvirtual machines, storage , and networking component .

2. PaaS (Platform as a Service)

• It provides a platform and a environment for developers to build, deploy, and manage applications without dealing with the underlying infrastructure.
• It offers tools and services such as development frameworks, databases, and middleware, streamlining the application development lifecycle.

3. SaaS (Software as a Service)

• SaaS elivers software applications over the internet on a subscription basis. It eliminating the need for users to install, maintain, or update the software locally.
• With this service users can access the applications from any device with an internet connection, enabling flexibility and accessibility.

4 . Serverless Computing

• serverless computing is provides provide abstract for server management , facilitate developer to focus completely on develop and deploy code without manage server .
• It automatically scales the resources based on demand, reducing the operational overhead and costs, and enabling rapid development and deployment of applications.

What are the types of Cloud Services?

The following is are are the type of cloud also know as cloud deployment model as follow :

1. Public cloud
2. Private cloud
3. Hybrid cloud
4. Community cloud
5. Multicloud

1 . Public Cloud

• Public clouds are managed by third parties which provide cloud services over the internet to the public, these services are available as pay-as-you-go billing models. 
• They offer solutions for minimizing IT infrastructure costs and become a good option for handling peak loads on the local infrastructure. Public clouds are the go-to option for small enterprises, which can start their businesses without large upfront investments by completely relying on public infrastructure for their IT needs. 
• The fundamental characteristics of public clouds are multitenancy. A public cloud is meant to serve multiple users, not a single customer. A user requires a virtual computing environment that is separated, and most likely isolated, from other users. 

example: Amazon EC2, IBM, Azure, GCP

Advantages of Public Cloud

The following are the advantages of public cloud:

• Public cloud is easily able to scale up and down resources as per the demand of traffic and workload. It facilitates with performance optimization and cost efficiency.
• It works on pay-as-you-go cloud model and helps in resolving the investments needs in hardware and infrastructure reducing overall costs.

disadvantage of using Public Cloud

The following are the disadvantages of Public Cloud:

• It is is is difficult to trust and maintain datum to a third – party provider may raise concern about control and ownership
• The shared infrastructure of public cloud resources increases the risk of data breaches and unauthorized access. It raises security and privacy concerns.
• Public cloud comes with limited transparency about the underlying infrastructure which may make it challenging to monitor and manage performance effectively.

2. private cloud

• Private clouds are distributed systems that work on private infrastructure and provide the users with dynamic provisioning of computing resources. Instead of a pay-as-you-go model in private clouds, there could be other schemes that manage the usage of the cloud and proportionally billing of the different departments or sections of an enterprise. private cloud providers are HP Data Centers, Ubuntu, Elastic-Private cloud, Microsoft, etc.

example: VMware vCloud Suite , OpenStack , Cisco Secure Cloud , Dell Cloud Solutions , HP Helion Eucalyptus

advantage Of Private Cloud

• Customer information protection: In the private cloud security concern are less since customer datum and other sensitive information do not flow out of private infrastructure .
• Infrastructure ensuring SLAs: private cloud is provides provide specific operation such as appropriate clustering , datum replication , system monitoring , and maintenance , disaster recovery , and other uptime service .
• Compliance with standard procedures and operations: specific procedures is have have to be put in place when deploy and execute application accord to third – party compliance standard . This is is is not possible in the case of the public cloud .

Disadvantages Of Private Cloud

• The restricted area of operations: private cloud is is is accessible within a particular area . So the area of accessibility is restrict .
• Expertise requires:  In the private cloud security concerns are less since customer data and other sensitive information do not flow out of private infrastructure. Hence skilled people are required to manage & operate cloud services.

3. Hybrid cloud

• A hybrid cloud is a heterogeneous distributed system formed by combining facilities of the public cloud and private cloud. For this reason, they are also called heterogeneous clouds. 
• A major drawback of private deployments is the inability to scale on-demand and efficiently address peak loads. Here public clouds are needed. Hence, a hybrid cloud takes advantage of both public and private clouds. 
• example: AWS Outposts, Azure Stack, Google Anthos, IBM Cloud Satellite, Oracle Cloud at Customer

  Advantages of using Hybrid cloud

The following are the advantages of using Hybrid Cloud:

• hybrid cloud is is is available at a cheap cost than other cloud because it is form by a distribute system .
• It works comes up with working fast with lower cost and facilitates in reducing the latency of the data transfer process.
• Most important thing is is is security . A hybrid cloud is is is totally safe and secure because it work on the distribute system network .

Disadvantages of Using Hybrid Cloud

The following are the disadvantages of using Hybrid Cloud:

• It’s possible that businesses lack the internal knowledge necessary to create such a hybrid environment. Managing security may also be more challenging. Different access levels and security considerations may apply in each environment.
• Managing a hybrid cloud may be more difficult. With all of the alternatives and choices available today, not to mention the new PaaS components and technologies that will be released every day going forward, public cloud and migration to public cloud are already complicated enough. It could just feel like a step too far to include hybrid.

• Community clouds are distributed systems created by integrating the services of different clouds to address the specific needs of an industry, a community, or a business sector. But sharing responsibilities among the organizations is difficult.
• In the community cloud, the infrastructure is shared between organizations that have shared concerns or tasks. An organization or a third party may manage the cloud. 
• example: CloudSigma, Nextcloud, Synology C2, OwnCloud, Stratoscale

Advantages of Using Community Cloud

The following are the advantages of using Community Cloud:

• Because the entire cloud is shared by numerous enterprises or a community, community clouds are cost-effective.
• Because it works with every user, the community cloud is adaptable and scalable. Users can alter the documents according to their needs and requirements.
• Public cloud is less secure than the community cloud, which is more secure than private cloud.
• Thanks to community clouds, we may share cloud resources, infrastructure, and other capabilities between different enterprises.

disadvantage of using Community Cloud

The following are the disadvantages of using Community Cloud:

• Not all businesses should choose community cloud.
• Gradual adoption of data
• It’s challenging for corporations to share duties.

Applications is clouds Of Community cloud

The following is are are the application of community cloud :

• Media industry: Media companies are looking for quick, simple, low-cost ways for increasing the efficiency of content generation. Most media productions involve an extended ecosystem of partners. In particular, the creation of digital content is the outcome of a collaborative process that includes the movement of large data, massive compute-intensive rendering tasks, and complex workflow executions.
• Healthcare industry: In the healthcare industry community cloud are used to share information and knowledge on the global level with sensitive datum in the private infrastructure .
• Energy and core industry: In these sectors, the community cloud is used to cluster a set of solution which collectively addresses the management, deployment, and orchestration of services and operations.
• Scientific research: In this organization with common interests in science share a large distributed infrastructure for scientific computing.

5. Multicloud

• Multicloud is the use of multiple cloud computing services from different providers, which allows organizations to use the best-suited services for their specific needs and avoid vendor lock-in.
• This is allows allow organization to take advantage of the different feature and capability offer by different cloud provider .
• example: Cloud Foundry , Kubernetes , Apache Mesos , Red Hat OpenShift , Docker Swarm

advantage of using Multi – Cloud

The following are the advantages of using multi-cloud:

• flexibility: Using multiple cloud providers allows organizations to choose the best-suited services for their specific needs, and avoid vendor lock-in.
• Cost-effectiveness: Organizations can take advantage of the cost savings and pricing benefits offered by different cloud providers for different services.
• improved performance: By distributing workloads across multiple cloud providers, organizations can improve the performance and availability of their applications and services.
• Increased security: Organizations can increase the security of their data and applications by spreading them across multiple cloud providers and implementing different security strategies for each.

Disadvantages of using Multi-Cloud

The following are the disadvantages of using Multi-Cloud:

• Complexity: Managing multiple cloud providers and services can be complex and require specialized knowledge and expertise.
• increase cost : The cost is be of manage multiple cloud provider and service can be high than using a single provider .
• compatibility issue: different cloud providers is use may use different technology and standard , which can cause compatibility issue and require additional resource to resolve .
• limited interoperability : different cloud providers is be may not be able to interoperate seamlessly , which can limit the ability to move datum and application between them .
