What Is Cloud Computing? Things Need To Known From Basics

What is Cloud Computing?

Cloud computing is an innovation that uses the internet, web, and central remote servers to take care of data information and applications. cloud computing permits buyers and organizations to utilize applications without establishment and access their documents on any PC with internet access. This technology allows efficient computing by memory handling and data transmission.

cloud computing comprises of shared processing assets that are virtualized and accessed as a service, through an API. The cloud empowers clients in an association to run applications by conveying them to the cloud, a virtual datacenter. The physical assets may reside in various areas inside and outside of an association: on local hardware, in an undertaking server farm, or at remote or managed service providers on a pay-to-use basis. cloud computing assets are offered as service dependent upon the situation, and conveyed by IP-based network, giving profoundly adaptable, solid on-request benefits with agile administration abilities.

Advantages of Cloud Computing:

• Cost Savings – Reduce the cost of managing your IT systems
• Scalability – Take care of all IT hosting and infrastructure
• Security- Cloud host’s carefully monitor security
• Automatic Software Updates- It automatically refresh and update software themselves
• Mobility – Allows access to corporate data via smartphones
• Loss Prevention – The information you’ve uploaded to the cloud remains safe 
• Insight – Offer integrated cloud analytics to view you data
• Disaster Recovery – Provide quick data recovery for all kinds of emergency scenarios
• Increased Collaboration – Members can view and share information across the cloud platform
• Quality Control – Maintain’s consistency in data and avoid human error

Types of cloud computing

Platform as a Service (PaaS)

PaaS its all about giving the devices and support required for the successful development of uses utilizing the cloud as a platform. As a matter of fact, the PaaS merchants focus on the provisioning of framework to the designers who are not having access to the resources required for making applications. Example: Google App Engine, AWS Elastic Beanstalk,Windows Azure.

Infrastructure as a Service (IaaS)

IaaS seller gives an exceptionally adaptable and computerized foundation in which you can store your information, figure out how to host, and work on all the capacities identified with processing and systems administration 

Example: Digital Ocean, AWS, Microsoft Azure, Cisco Metapod, Rackspace, Linode

Software as a Service (SaaS)

software as a Service could be characterized as a shared Software that is claimed by third-party service provider. SaaS empowers various elements to utilize the product for business purposes by buying a membership of the equivalent. 

Examples:Google Apps, Salesforce, Hubspot, Zendesk

Types of SaaS

Business Utility SaaS – Applications like Salesforce automation are used by businesses and individuals for managing and collecting data, streamlining collaborative processes and providing actionable analysis. Most popular uses are respectively: Customer Relationship Management (CRM), Human Resources and Accounting.

Social Networking SaaS – Applications like Facebook are used by individuals for networking and sharing information, photos, videos, etc.

Types of PaaS

Platform-as-a-Service (PaaS) solutions are created equal. Choose the platform which suits your needs carefully:

Social Application Platforms – Platforms like Facebook provide APIs so third parties can write new application functionality that is made available to all users.

Computing Platforms – Platforms like Amazon Web services, Rackspace, Opsource and others provide storage, processor, and bandwidth as a service. As a developer you can upload traditional software stack and run applications on their computing infrastructure.

Web Application Platforms – Google Apps provide APIs and functionality for developers to build Web applications that leverage its mapping, calendar, and spreadsheets plus YouTube and other services. More ideal for light weight web applications!

Business Application Platforms – Platforms like WOLF provide a higher layer of abstraction from technical complexities and is specifically geared toward transactional business applications such as database, integration, workflow, and user interface services. Developers & business analyst can develop complex and robust business applications and also create customized user interface – providing higher freedom with lesser efforts.

Types of IaaS There are also different types of cloud IaaS providers, depending on what you looking for:

• Computing, Storage, and Bandwidth
• Development and Test
• High-Performance Computing
• Resource Sharing

Classification of the Cloud Deployment Model

Private cloud. Private cloud arrangements are devoted to one association or business, and frequently have considerably more explicit security controls than a public cloud. Numerous clinical workplaces, banking foundations, and different associations who are needed to meet government and state rules for information controls utilize a private cloud. 

Public cloud. Public cloud is made from third-party  assets, which get shared between numerous associations. This makes the public cloud supplier a merchant which is giving virtual PC assets to the association.

Hybrid cloud. Hybrid cloud solutions are a blend of public and private clouds. This is a more complex cloud solution in that the organization must manage multiple platforms and determine where data is stored. An example of a hybrid cloud solution is an organization that wants to keep confidential information secured on their private cloud, but make more general, customer-facing content on a public cloud

According to CIO In particular, it listed three deployment models for cloud computing

1. Public clouds. These deliver the best economies of scale, but their shared infrastructure model can limit configuration, security, and SLA specificity, making them a less-than-ideal fit for services using sensitive data that is subject to compliance or safe harbor regulations.
2. Internal clouds. These sit within your data center and behind company-built protections, but they typically have modest economies of scale due to funding limitations and tend to be less automated.
3. Hosted clouds. Hosted clouds run at a service provider on resources that are walled off with enterprise-class protections but managed as a pool. These fall between the first two options, providing more custom protections like an internal cloud but with greater economies of scale of being a service from a cloud provider.
