Cloud computing may be a reasonably outsourcing of computer code, knowledge storage, and process. Users access applications and files by work in from any device that has an online affiliation. Data and programs are hosted by outside parties and reside on a world network of secure knowledge centers rather than on the user’s Winchester drive. This frees up process power, facilitates sharing and collaboration, and permits secure mobile access no matter wherever the user is or what device is being employed. Cloud computing is term of everything that involves delivering hosted services over the internet, the services are broadly divided into three categories like:

  1. SaaS (Software as a Service): SaaS is the most common type of cloud computing, which delivers complete user friendly applications over the internet.
  2. PaaS (Platform as a Service):  It is the category of cloud computing. PaaS provide the building block for the software creation, including development tools, code libraries, servers, programming environments and many more.
  3. IaaS (Infrastructure as a Service): It is the part of infrastructure services. This is self-services model for accessing, monitoring and managing remote infrastructure, such as compute, storage, networking and networking services.

Cloud computing is much better for delivering computing resources. With cloud computing, software and service environments are subscription based so users can pay a monthly fees instead of buying the licenses. All the software and platforms are managed by the providers and updates continuously for better performance and security. The computing power is remote so users can tap into extra capacity if business spikes. Multiple people can access a shared program or file in real time from different locations.

Cloud computing deployment model:

  1. Private Model- Private Cloud is also known as internal cloud or corporate cloud. Private Model deliver from a business’s data center to internal users. This model offers the elastic and comfort of the cloud, while preserving the management, control and security common to local data centers. A private cloud is dedicated to the requirements and goals of a single organization.
  2. Public Model- Public model a third party cloud services provider delivers the cloud services over the internet. Public cloud services are on demand now a days, typically by the minute or hour, though long-term commitments are available for many services. Leading public cloud service providers include Amazon Web Services, Microsoft, and IBM and google cloud platform.
  3. Hybrid Model- Hybrid cloud is a Cloud computing that uses both of private and public cloud services with orchestration between the two platforms. Hybrid cloud gives businesses better mouldability and more deployment options.

 

Benefits of cloud computing-

Here are some common benefits or we can say the reasons organizations are turning to cloud computing services:

  1. Cost- By using cloud computing, you don’t need to spend huge amount of money on purchasing and maintain equipment. You don’t have to invest in hardware, facilities, utilities or building out a large data center to boosts up your business. You don’t even require large IT teams to handle your cloud data center operations, as you can enjoy the expertise of your cloud provider’s staff.
  2. Speed- Most cloud computing services are provided self-service and on demand, so even large amount of computing resources can be equipped in minutes, with just a few mouse clicks, giving business a lot of mouldability and the capacity.
  3. Security- Security of data is the major concerns for every business. Cloud offers many advanced security features that guarantee that the data is securely stored, safe and handled.
  4. Scalability- Different companies have different requirements. A large company of 500+ employee won’t be the same requirements as a start-up company. Cloud is a great solution because it enables enterprise to systematically and quickly scale up/down their IT departments, according to business demands. If your business demands increase, you can easily increase your cloud capacity easily. This scalability minimizes the risks associated with the business. Scalability is probably the best advantage of the cloud.
  5. Productivity- Businesses requires a lot of hardware setup, software patching and other time consuming IT management tasks, so the cloud computing removes the requirements for many of these tasks, so IT teams can spend more time on achieving more important business goals.
  6. Performance- The biggest benefit of cloud computing is its performance. The biggest cloud computing services run on a worldwide network of secure data centers that are unit frequently upgraded to the latest generation.
  7. Reliability– Cloud computing makes data backup, data recovery and business continuity easier and fewer overpriced as a result of data can be reflected at multiple redundant sites on the cloud provider’s network.
  8. Control- Having control over delicate data is important to any company. Cloud enables you complete transparency and control over your data. You decide that which users have what level of access to what data.
Use of cloud computing

Cloud computing is very useful now a days. Here are a few examples of what is possible today with cloud services from a cloud provider:

  • Create cloud-native applications – Quickly build, deploy and scale web and mobile applications and API. Take benefits of cloud-native technologies.
  • Test and build applications – Minimize application development cost and time by using cloud infrastructure that can easily be scale up or down.
  • Store, backup and recover data – Protect your data at a massive scale by transferring your data over the internet with any device from any location with cloud computing.
  • Analyse Data – Use cloud services for better analyzing your data. Use machine learning and artificial intelligence to uncover insights for more informed decisions.
  • Stream audio and video – By using cloud computing services you can connect with your audience anytime, anywhere, on any device with high definition video and audio with all over the world.
  • Deliver Software on Demand – SaaS (software as a service) is a cloud computing service, and also an on-demand service. So by using this service you can take benefit at anytime, anywhere.
