Prior to the introduction of cloud hosting systems, there were two ways to provide web hosting services — using a physical or virtual private server or a cluster type pfc computer (server) pf. The most common is to use a separate physical server to host the website as a virtual hosting account. Virtual hosting is a method of hosting multiple websites and domain names on private servers. Web accounts are divided into separate directories and are all divided into CPU, memory, and resources on the physical core server.
Most shared hosting accounts are “name-based” accounts. “Name-based” means that the host domain uses multiple names and/or domain names running on IP addresses. For example, a server can receive domain requests, domain1.com, domain2.com, domain3.com, domain4.com, domain5.com, etc. Everyone has their own IP address. But, for example, if the server receives an HTTP request for domain1.com, it will send it to an HTML file in the / var / www / user / domain1 / site / directory, etc.
The disadvantage of virtual hosting is always the burden of the server, and different accounts are created when they need a lot of resources. Before the cloud comes out, there is only one way to solve the load problem. It is the creation of a kind of physical server cluster to distribute the computing number. Although it is technically feasible, it is not a common way to optimize a virtual hosting system because of the way automated server software (control panel) works.
They often lock one of the physical hosts to the CPU and physical hardware, so they cannot run normally in a multi-server environment. Therefore, those who developed shared hosting before cloud deployment have no choice but to view it as a virtual technology that can work in a multi-server environment. They have to handle the daily load and can’t share the load in other cases, and can’t maximize the CPU and RAM resources of the physical or virtual servers hosting the virtual accounts.
How Is Cloud Computing Changing?
In every service area, cloud computing has improved web hosting. For example, cloud infrastructure in the VPS marketplace allows remote virtual servers to go up and down immediately. Cloud systems in the virtual hosting market (shared hosting) do not allow the expansion of cloud-based virtual hosting. It allows failover and a multi-user interface.
High accessibility (HA) is a strategy to quickly drive an online system after an operating system (OS) failure or a physical server using certain virtual hosts, in order to prevent computer system failures and the provision of sharing management services. HA is often a function of overload control, operating system failure, or overload in computing cases.
If something happens, it will either revert to the same physical server or start again when another physical host (found in the cloud hosting system section) shuts down the cloud-computing here. The main purpose of high gain is to reduce service downtime rather than avoid outages. The virtual server used to provide online computing services is back fast.
Failover refers to the ability of a cloud management system to continue to provide uninterrupted service when an operating system or device fails. There are various technologies and solutions for failover. Importantly, in the event of a failure, failover (or error tolerance) can transfer the load from the failed computing node (server) to the new computing node (server).
Web hosting service providers should take care of the server load before deploying to the cloud, shutting down overused virtual accounts with software, migrating to a new host, or setting up a separate VPS. or a dedicated server. Today, cloud computing systems allow providers to expand the resources of the servers used to deliver web hosting services in real-time.
