With the rise in cloud usage by both professionals as well as regular users, the need for servers has increased rapidly. Earlier, the entire computing process was created and managed by the organization, or else they cannot run their software applications. Not only was it a tedious task but consumed a lot of money as well. However, the improving technology came up with a solution called Cloud Computing. This article will talk all about cloud computing, its types, languages, and other numerous things.
What is Cloud Computing?
Cloud computing is providing the entire package of computing services to the user over the internet. This mode of software delivery has created a new model that is used by organizations. In the traditional method, the company plans to provide software to the user. Not only has to bear the cost of developing the software but the hardware aspects as well. In cloud computing, the organization does not have to obtain or manage any physical servers as these are done by a third-party provider.
Furthermore, the biggest limitation in the traditional method was that in most of the cases, the physical servers held by the organization were not utilized up to their potential, making these resources go in vain. This factor made computing solutions expensive for small-scale enterprises. However, cloud computing has solved this issue by providing the companies only what they need. Cloud computing solutions are customizable and the users can determine how much cloud storage or services they need depending on their requirements. Doing so ensures that they only get sufficient server space for their task, allowing them to cut unnecessary expenses.
Models of Cloud Computing
As mentioned above, cloud computing has given organizations the option to customize the services as per their requirements. With that in mind, there are four different models of cloud computing that organizations can choose from.
- Software-as-a-Service (SaaS): Software-as-a-Service is among the most widely used cloud computing models in the present time. Here the software service or the application is provided through the internet by using a web browser. In the majority of cases, the services are delivered on a subscription basis, but it entirely varies with the software and the organization providing it. The biggest benefit of using SaaS for an organization is the eradication of hosting and managing the software application and the infrastructure. Be it software upgrades, maintaining the physical server, or adding a security layer to the program, everything is handled by the cloud computing service provider. Microsoft 365, Salesforce, Slack, and MailChimp are some of the biggest examples of SaaS programs.
- Function-as-a-Service (Faas): Also referred to as serverless computing, this cloud computing model segregates the code into smaller components that are triggered upon a certain action and will only be used when needed. Akin to other models, they also run on servers, but the user does not have to manage any server for building or using the software. One key factor about the FaaS model is that even though it is similar to the IaaS model, it does not use its resources until an event triggers it. Due to this reason, the pay-per-use fee is only charged only when it is actually used. Top cloud providers including Microsoft Azure Functions, IBM OpenWhisk, and AWS Lambda provide FaaS.
- Infrastructure-as-a-Service (IaaS): Providers like Amazon Web Services (AWS) offer Infrastructure-as-a-Service where they offer a virtual server and storage along with an application programming interface where the users can migrate their workload to a virtual machine. Depending on the requirements of the users, these providers can offer large, medium, and small storage capacity where they have the ability to start, stop, access, and modify the virtual machines. In other words, IaaS lets users create a data center virtually without the need to bear the expenses of acquiring or maintaining physical servers or data centers. Apart from AWS, Google Compute Engine, and DigitalOcean are some other IaaS providers.
- Platform-as-a-Service (PaaS): When it comes to building an application, resources like operating systems, development tools, and infrastructure are necessary. In the Platform-as-a-Service model, the vendors provide all these resources to the organization over the internet to build their applications and they do not have to pay for any hosted application. Rather than getting all the resources available, the companies only get the resources they truly need to build the applications, hence saving a lot of their expenses for completing this action. The vendor will be the one maintaining the resources as well as the infrastructure. Google App Engine and AWS Elastic Beanstalk are some of the biggest examples of PaaS products.
Types of Cloud Deployments
The models of cloud computing showcase the way how services are provided in cloud computing. However, there are several types of cloud deployments that vary with their nature, management, and other numerous factors.
- Public Cloud: As the name suggests, Public clouds are cloud environments that are not owned by direct users. The location of most of the public clouds is not on the premises of the user. Rather they are located in different areas of the globe and a certain amount of the cloud is given to the user. Providers like Google Cloud, Amazon Web Services, and Microsoft Azure offer public clouds to tons of organizations. Even though the cloud is public, the access to the specific data owned by the end-user is restricted, and only authorized subscribers can use the resources.
- Private Cloud: Every cloud environment made solely for an individual user or a group is a private cloud. Only the owner uses and maintains the cloud and it mostly runs behind their firewall as well. In other words, a private cloud is any cloud whose IT infrastructure is dedicated to a single entity. In most cases, the private cloud is located on the user’s premises and only they are authorized to access it. However, with the changing trends, the need of having a private cloud on-premises is changing. Private clouds can now be rented on off-premises data centers, making the ownership of the cloud easier for the end-user.
- Hybrid Clouds: Hybrid cloud is the perfect blend between public and private cloud that has an orchestration between them. In this cloud computing, the organizations may get a public or a private cloud and switch between the two whenever necessary or when requirements change. One of the best things about hybrid cloud is that they provide the utmost flexibility and better deployment options to the user including network and hosting. Furthermore, by choosing the right environment for the set purpose, hybrid clouds are proven to be better at cost management than the other two.
- Multi-Cloud: When it comes to using cloud services, a single cloud provider is preferred to support one or more applications by an organization. Multi-cloud deployment is where several cloud services are used from multiple providers. The reason why multi-cloud setup is used by legions of organizations is that they reduce the dependency of the organization on any single cloud service provider. Even though it is rare with reliable cloud providers, downtime still persists that can hamper the overall functioning of the organization. Multi-cloud deployment saves such organizations by minimizing the effect of downtime or data loss by a provider.
