Unlock the Value of Cloud Computing
A model for enabling ubiquitous, practical, on-demand network access to a pool of configurable computing resources (such as networks, servers, storage, applications, and services) that can be quickly provisioned and released with little administration work or service provider interaction is known as cloud computing. Cloud computing is a term used to describe massive data centers that are accessible to a large number of users and organizations and offer significant economies of scale, scalability, and engineering redundancy. Furthermore, the word cloud computing refers to the utilization of computer resources delivered through the Internet. This article provides an overview of emerging cloud computing technologies and key essential characteristics of the cloud.
In 2020, the market for cloud computing was valued at $ 371.4 billion, and by 2025, it is anticipated to reach $ 832.1 billion.
Essential Characteristics of Cloud Computing
The essential characteristics of cloud computing help define what a cloud environment is. Many IT applications and services are hosted in offsite data centres. But that doesn't make the computing environment a true cloud environment. The environment should have the following five main characteristics: on-demand self-service, broad network access, resource pooling / multi-tenant access, rapid elasticity, and measured service.
Types of Cloud Deployments
The cloud deployment model is determined by the location of the deployment infrastructure and who has control over that infrastructure. There are three basic deployment methods to consider: private, public, and hybrid.
𝐏𝐫𝐢𝐯𝐚𝐭𝐞 𝐜𝐥𝐨𝐮𝐝: Computing resources, hardware, software, and network devices are used exclusively by a single organization, with no resources shared between organizations. Computing resources are provided to users through a private network. A private cloud can be co-located with another company's facilities or physically located at a company's headquarters (i.e., on-premises or off-premises). Private clouds can be managed and maintained by a third party or by the company itself.
𝐏𝐮𝐛𝐥𝐢𝐜 𝐜𝐥𝐨𝐮𝐝: Computing resources, hardware, software, and networking devices are owned and managed by third-party vendors, and therefore the use of hardware, storage, and networking devices is shared across multiple consumer organizations. Computing resources are made available to consumers over the public Internet. Public cloud services may be provided to consumers free of charge or through various subscription or on-demand pricing models, including pay-as-per-usage models.
𝐇𝐲𝐛𝐫𝐢𝐝 𝐜𝐥𝐨𝐮𝐝: It combines on-premises data centers and private clouds with public clouds, allowing organizations to combine aspects of any type of data center deployment. In addition, there is an orchestration between the two environments. Cloud orchestration is the use of programming techniques to manage connections and interactions between workloads in public and private clouds. A Hybrid cloud allows organizations to use a private cloud to host sensitive or critical applications and a public cloud to host non-critical applications.
Cloud Computing service models
Three main cloud service models represent unique ways to deliver computing, development, and application functionality to consumers over the Internet: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞-𝐚𝐬-𝐚-𝐒𝐞𝐫𝐯𝐢𝐜𝐞 (𝐈𝐚𝐚𝐒): With the help of laaS, the customer can access the fundamental resources of the cloud infrastructure. IaaS provides virtual machines and other hardware and abstract operating systems. IaaS provides the customer with processing, storage, networking, and other fundamental computing resources so that the customer can deploy and run the software of their choice, including operating systems and applications. IaaS allows customers to combine core computing services, such as network processing and data storage, to create highly interoperable computing systems. Typically, customers can build this infrastructure using a web-based GUI that acts as an IT operations management console for the overall environment. Access to the application programming interface (API) infrastructure can also be offered as an option. Examples of laaS include Amazon Elastic Compute Cloud (Amazon EC2), Microsoft Windows Azure, Google Compute Engine, and Rackspace.
𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦-𝐚𝐬-𝐚-𝐒𝐞𝐫𝐯𝐢𝐜𝐞 (𝐏𝐚𝐚𝐒): A PaaS cloud provides services to customers in the form of a platform on which customer applications can run. PaaS allows customers to deploy applications on the cloud infrastructure. A PaaS cloud provides software building blocks as well as several development tools, such as programming language tools, runtime environments, and other tools that help deploy new applications. In Fact, PaaS is an operating system in the cloud. PaaS is helpful for an organization that wants to develop new or customize applications and pay for computing resources only for as long as is necessary. App Engine, Engine Yard, Heroku, Microsoft Azure, Force.com, and Apache Stratos are examples of PaaS.
𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞-𝐚𝐬-𝐚-𝐒𝐞𝐫𝐯𝐢𝐜𝐞 (𝐒𝐚𝐚𝐒): As the name implies, cloud SaaS provides services to customers in the form of software, especially application software, that runs and accesses in the cloud. SaaS follows the familiar web service model in the case of cloud resources. SaaS allows customers to use CP applications running on the provider's cloud infrastructure. Applications are accessible from different client devices through a simple interface like a web browser. Instead of getting desktop and server licenses for the software products they use, a business gets the same functionality from a cloud service. Using SaaS avoids the hassles of software installation, maintenance, upgrades, and patches. Examples of services at this level are Google Gmail, Microsoft 365, Salesforce, Citrix GoToMeeting, and Cisco WebEx.
In general, all three cloud service models minimize the hardware and software investments an organization must make to implement an on-premises data center. In each cloud service model, an external organization manages a shared data center and provides virtual computing resources, development environments, or hosted applications to consumers over the Internet
Conclusion
Cloud computing delivers sophisticated computing resources that are available when required, extensible as needed, updated regularly, and do not need the purchase and maintenance of on-premises infrastructure. Because cloud computing allows organizations to instantly acquire and expand services without the significant overhead of operating traditional on-premises infrastructure, companies become more efficient and reduce time to market.
