What is Cloud Hosting? Features and Types
What is Hosting?
When a customer or user wants to host a website or web application that can be accessed via the Internet, the hosting service is provided by a server. A server is a system that offers users data storage, resources, software tools, and interfaces, and when the web page is hosted on the Internet, people can interact with it.
What is Cloud Hosting?
Cloud hosting is the process of hosting web pages or websites by dividing the data across multiple machines instead of storing it on a single server. This hosting service uses interconnected servers connected to the larger network, allowing data to be shared among the distributed virtual servers.
How Cloud Servers Work?
Cloud servers operate on multiple servers within a different network, and if any server experiences a major issue and fails, the data can be transferred or moved to another server on the cloud. This improves efficiency and enhances the redundancy of the website, ensuring continuous data access to customers without delay.
Features of Cloud Hosting
The following are the features of cloud hosting −
- Cloud − Applications and solutions are hosted on a cloud network instead of a single on-premises server.
- Scalability − Resources adjust to meet user requirements.
- Pay-as-you-go − Organizations are charged solely for the resources they consume.
- Language support − Cloud hosting can accommodate SQL databases like MySQL, as well as NoSQL databases.
- Automation − Solutions are automated and managed through APIs, web portals, and mobile apps.
Types of Cloud Hosting
All major cloud providers, such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud, and IBM Cloud®, offer cloud hosting, which includes the following cloud-based deployment models −
Public cloud − A public cloud is a cloud computing model where a third-party provider delivers computing resources to users through the public internet. These resources may include software applications ready for use, individual virtual machines (VMs), full enterprise-grade infrastructures, and development platforms.
Private cloud − A private cloud refers to a cloud computing environment where all hardware and software resources are solely dedicated to and accessible only by one customer.
Hybrid cloud − The hybrid cloud merges public cloud, private cloud, and on-premises infrastructure into a single, adaptable, cost-effective IT infrastructure. Today, many enterprises rely on a hybrid multicloud strategy, which combines public cloud, private cloud, and on-premises infrastructure with cloud services from at least two cloud providers.
Why is Cloud Hosting Popular?
The cloud platform includes all necessary hardware and software tools or applications and can function as an independent server system. Cloud services allow users to scale resources on demand across multiple servers connected to the host server, ensuring better performance even during traffic spikes. For this reason, this type of hosting is preferred for websites with high daily traffic. Cloud hosting systems have gained popularity recently, especially among large organizations with extensive networks, where cloud services from well-known providers like Amazon, Microsoft, Google, etc., are used.
Benefits of Cloud Hosting
The following are the benefits of cloud hosting −
- Flexibility − You can rapidly adjust your applications to scale up or down.
- Reliability − Cloud hosting involves multiple servers, reducing the risk of failure.
- Cost − You only pay for the resources you use, avoiding the need to overprovision.
- Performance − Cloud hosting helps enhance page load speed and customer interaction.
Cloud Hosting Security
Security in cloud hosting is a shared responsibility between the client and the provider. It includes a variety of policies, procedures, and technologies that deal with both external and internal threats to business security. Cloud hosting providers offer strong security features to protect against malicious threats, such as firewalls, identity management tools, SSL, data loss prevention, regular updates, and 24/7 monitoring. Cloud data centers also have physical security measures like surveillance and guards to prevent unauthorized access.
Managed cloud services
Managed cloud services refer to the full or partial oversight and management of a client's cloud resources. The goal of managed cloud services is to delegate cloud management tasks to an "as a service" provider. This allows businesses to ensure that cloud resources are functioning optimally without the need to invest in hiring a dedicated team for management. Depending on the business and technical requirements, the managed service provider may handle tasks such as cloud migration, optimization, security, configuration, system updates, and more.
Here are some leading managed cloud services −
Infrastructure as a service (IaaS)
IaaS provides on-demand access to IT resources, including cloud-hosted physical and virtual servers, virtual machines, cloud storage, and networking. It essentially offers all the back-end IT infrastructure required to run applications and workloads in the cloud.
Platform as a service (PaaS)
PaaS is a cloud computing framework that delivers a comprehensive cloud platform, including hardware, software, and infrastructure. It enables the development, execution, and management of applications without the costs and complexities tied to building and maintaining an on-premises platform. Red Hat® Open Shift® is a widely-used PaaS built on Docker containers and Kubernetes, which is an open-source orchestration tool that automates deployment, scaling, load balancing, and more for containerized applications.
Software as a service (SaaS)
SaaS is cloud-hosted application software that is ready to use and is offered on a subscription basis. Presently, SaaS is the most prevalent public cloud service and the main software delivery method. A Statista report estimated the SaaS market to be worth about 197 billion US dollars in 2023, with projections to grow to 247 billion US dollars in 2024.
Serverless
Serverless is a model for developing and running applications where developers can create and execute code without the need to provision or manage servers or back-end infrastructure.
