As we all know that Cloud computing is demanding technology which is provides the computing resources such as servers, storage, databases, software, Infrastructure, on demand services and networking over the internet. Instead of having on-premises infrastructure to purchase and maintain physical Server or Data centre , users can use these cloud services & resources on-demand based and pay only for what they use.
How does cloud computing work?
Cloud computing divided in multiple layer or services and all requirement and demand will be part of any of these services:
- Infrastructure as a Service : IaaS
- Platform as a Service : PaaS
- Software as a Service : SaaS
- Network as a Service: NaaS
Infrastructure as a Service (IaaS):
As It’s name says Infrastructure, so what we understand that this services is related to some infra related services. So, with this service user can access third party hosted servers and compute resources like Server, Storage, network and OS and user no need to purchase or maintain any hardware on their end. User only need to access and pay as usage of those Infrastructure.
Some of the key benefits of IaaS include:
- Flexibility: With IaaS user, user had flexible to access cloud infra as per their requirement and he can scale up or add the resources as per their requirement without procuring any physical hardware, once requirement is fulfill user can release them.
- Cost savings: By outsourcing IT infrastructure management, businesses can save on the cost of hardware, maintenance, and personnel.
- Reliability: In Cloud services Reliability is one of the factor which makes it very popular and demanding. User will get high level of Availability and uptime , so user can access the services whenever he need.
- Security: Security is always a major concern for ICT and servers and IaaS providers provides high level of security to protect user’s data including Cyber attack, unauthorized access with encryption, firewalls, and IPS/IDS without investing any cost in Infrastructure.
- Ease of use: With IaaS customer can access their infra easily from anytime and anywhere
Platform as a Service (PaaS):
It is cloud compute model in which third party Provides a platform on which user can develop, run, test and manage their applications without having on-prim infrastructure. User need to share their requirement and they will get their platform and need to pay as per usage.
Key benefits of PaaS include :
Including Cost Saving, Reliability and Scalability it will provides
- Pre-configured Platform: offer Pre-configured platforms or environments that allow developers to quickly build and deploy applications without the need for extensive setup or configuration. It will make the development little faster.
- Collaboration: Some time we need to work with other developers on some requirement and PaaS allow developers to work together on projects and share resources, improving collaboration and productivity.
- Software as a Service (SaaS): Under this service user will get required software to work, test without install any software on their laptop or servers and can access to software applications over the internet. Also SaaS will provide Security and automatic Software updates.
Benefits of Cloud Computing
Cloud computing offers many benefits over traditional IT infrastructure, including:
- Cost-effectiveness: Cloud computing allows users to pay based on thy use and it reduced users cost of procuring IT Hardware. It is huge saving.
- Scalability: User doesn’t have that much option to scale their on-perm data centre once it was setup but with Cloud computing use can scale their resources as their usage and demand.
- Flexibility: User are flexible to access their Cloud Computing services from anytime, anywhere and from any devices over internet and it also provide option to use and release the resource. Such kind of flexibility is not possible with On-perm setup.
- Disaster recovery and business continuity: Cloud computing provides built-in redundancy and disaster recovery capabilities to ensure business continuity.
- Collaboration and accessibility: Cloud computing allows users to easily share resources and collaborate on projects from anywhere.
- Security: Cloud computing provides advanced security features to protect against Cyber threats and data breaches.
Common mis–conceptions about cloud computing
Although Cloud Computing is popular and have multiple benefits, but still there are some common misconceptions:
- Security concerns: Cloud Computing is not much secure as On-Premises.
- Loss of control: User will not have control on their data and privacy. But private cloud one of the option for sensitive data.
- Cloud Computing Is Only for Large Enterprises: Another misconception is that cloud is only for big project or big organizations, but an single user also using Gmail account as cloud service.
- Cloud Computing is very Expensive: Some User believes that Cloud computing is very expensive than On-Premises, but it not the truth. In reality cloud services are more cost efficient.
